Description

A display panel, a display panel driving method, and a display device

technical field

Embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel, a method for driving the display panel, and a display device.

Background technique

With the development of microdisplays, the requirements for the resolution of microdisplays are getting higher and higher. The traditional method of vapor deposition using a precision mask to achieve colorization will be limited by the precision of the mask and the size of the opening, and cannot meet the resolution requirements. Therefore, the existing micro-display mainly adopts the structure combining white light emitting device and color filter to realize colorization.

However, the combination of a white light-emitting device and a color filter to achieve colorization will sacrifice most of the brightness of the device, and a light-emitting structure with a single optical thickness cannot maximize the luminous intensity of pixels of different colors. In addition, in the structure combining the white light-emitting device and the color filter, there is a certain distance between the white light-emitting layer and the color filter, so that when the viewing angle changes, it is easy for the light emitted by the pixel to irradiate other elements. The light leakage phenomenon of the pixels makes the display effect of the microdisplay poor.

Based on this, it is an urgent problem to be solved in the industry to design a display panel to simultaneously solve the large brightness attenuation and the phenomenon of display light leakage when realizing colorization.

It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein can be practiced in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having", as well as any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or device comprising a sequence of steps or elements is not necessarily limited to the expressly listed instead, may include other steps or elements not explicitly listed or inherent to the process, method, product or apparatus.

An embodiment of the present invention provides a display panel. Fig. 1 is a schematic top view structure diagram of a display panel provided by an embodiment of the present invention, and Fig. 2 is a schematic cross-sectional structure diagram of a display panel cut along the direction A-A' in Fig. 1 provided by an embodiment of the present invention. Referring to FIG. 1 and FIG. 2 , the display panel includes: a substrate 10 , a plurality of first light emitting units 20 and a plurality of second light emitting units 30 .

Each first light emitting unit 20 includes a white light emitting structure 21 and a color filter layer 22 disposed on a side of the white light emitting structure 21 away from the substrate 10 , and the second light emitting unit 30 includes the white light emitting structure 21 .

The shape of the vertical projection of the first light emitting unit 20 on the substrate 10 is circular or elliptical, at least part of the first light emitting unit 20 is provided with the second light emitting unit 30, and the adjacent n first light emitting units 20 A second light emitting unit 30 is arranged between them; wherein, n is an integer greater than or equal to 3.

Specifically, the plurality of first light emitting units 20 and the plurality of second light emitting units 30 in the display panel are all disposed on the same side of the substrate 10 . The first light-emitting unit 20 includes a white light-emitting structure 21 and a color filter layer 22. The first light-emitting unit 20 relies on the combination of the white light-emitting structure 21 and the color filter layer 22 to make the white light emitted by the white light-emitting unit 21 pass through the color filter layer. After 22, it becomes colored light and emits, thereby realizing the colored display. Therefore, the first light emitting unit 20 is a color light emitting unit. The second light emitting unit 30 includes the white light emitting structure 21 , therefore, the second light emitting unit 30 is a white light emitting unit. The second light emitting unit 30 is used to emit light when the display panel displays a white image, so as to increase the display brightness of the display panel.

The first light-emitting units 20 are all set in a circular shape in vertical projection, or all the first light-emitting units 20 are set in a shape close to a circle, for example: the first light-emitting unit 20 can also be in the shape of an ellipse. Exemplarily, FIG. 1 shows a display panel structure in which the vertical projection of the first light emitting unit 20 is circular. A plurality of first light-emitting units 20 are arranged in a certain arrangement on the substrate 10 , and there are two tangent positions on opposite edges of two adjacent first light-emitting units 20 . At these two tangent point positions, the slopes of the tangent lines of the two first light emitting units 20 are the same. Therefore, the distance between two adjacent first light emitting units 20 is the shortest at the above two tangent points. At positions other than the closest position on two adjacent first light emitting units 20 , the distance between the two first light emitting units 20 gradually increases. Exemplarily, as shown in FIG. 1 , there are tangent points m and tangent points n on the opposite edges of two adjacent first light-emitting units 20 respectively. At the tangent point m and tangent point n, the two first light-emitting units 20 The slope is the same. Therefore, the distance d between the two adjacent first light-emitting units 20 at the tangent point m and the tangent point n is the smallest. The distance gradually increases. Setting the first light-emitting unit 20 in a circular or elliptical shape can realize that the distance between two adjacent first light-emitting units 20 gradually increases from the position of the tangent point with the same tangent slope to both sides. Therefore, the colored light emitted by the first light emitting unit 20 can be reduced from irradiating and emitting to the surrounding first light emitting units 20 , thereby effectively reducing the possibility of light leakage on the display panel.

The second light emitting unit 30 as a white light emitting unit is disposed in the gap between n adjacent first light emitting units 20 , where n may be an integer greater than or equal to three. Exemplarily, when n is equal to 3, three adjacent first light-emitting units 20 are arranged in a triangle, and the second light-emitting unit 30 can be disposed in the gap between the three adjacent first light-emitting units 20 . When n is equal to 4, four adjacent first light-emitting units 20 can be arranged in a rectangle, and the second light-emitting unit 30 can be disposed in the gap between the four adjacent first light-emitting units 20 arranged in a rectangle. When n is equal to 5, five adjacent first light-emitting units 20 can be arranged in a pentagon, and the second light-emitting unit 30 can be arranged in the middle of five adjacent first light-emitting units 20 arranged in a pentagon void. FIG. 1 shows the arrangement structure of the first light emitting unit 20 and the second light emitting unit 30 when n is equal to 4. When the display panel displays a white picture, the second light emitting unit 30 disposed in the gap between the adjacent n first light emitting units 20 can supplement the attenuated brightness of the white light emitted by the first light emitting unit 20 after passing through the color filter layer 22, Thereby, the overall display brightness of the display panel is improved.

It should be noted that, according to the precision of the manufacturing process of the display panel and the actual brightness requirement of the display panel, the number of the second light emitting units 30 can be adjusted. On the premise of meeting the brightness requirement of the display screen, the second light emitting unit 30 can be arranged between some adjacent n first light emitting units 20, thereby reducing the difficulty of manufacturing and improving the yield of the produced display panel.

In the display panel provided in this embodiment, a plurality of first light-emitting units and a plurality of second light-emitting units are arranged on one side of the substrate; wherein, the first light-emitting units include a white light-emitting structure and a color filter layer, and the first light-emitting units The unit is used as a color light-emitting unit; the second light-emitting unit includes a white light-emitting structure, so the second light-emitting unit is used as a white light-emitting unit. The vertical projection shape of the first light emitting unit is a circle or an ellipse, and the distance between two adjacent first light emitting units is the shortest at the tangent point where the slope of the tangent line of two adjacent first light emitting units is the same. From the position of the tangent point with the same slope of the tangent to both sides, the distance between two adjacent first light-emitting units gradually increases, so the colored light emitted by the first light-emitting units can be prevented from being emitted by the first light-emitting units arranged around , effectively reducing the possibility of light leakage on the display panel. In addition, in the display panel provided by this embodiment, the second light-emitting unit is arranged in the gap between n adjacent first light-emitting units, and when the display panel displays a white picture, the second light-emitting unit can increase the brightness of the display picture . Therefore, the display panel provided by this embodiment can effectively improve the display effect.

On the basis of the above-mentioned embodiments, referring to FIG. 1, FIG. 2 and FIG. In the light emitting unit 20 , each pixel column 201 is arranged along the second direction X; the second light emitting unit 30 is arranged between four adjacent first light emitting units 20 .

Specifically, on the substrate 10, a plurality of first light emitting units 20 may be arranged in an array. The first light emitting unit 20 arranged in an array includes a plurality of pixel columns 201 , and the plurality of pixel columns 201 are arranged in sequence along the second direction X. In each pixel column 201, a plurality of first light-emitting units 20 are arranged along the first direction Y, and the distance between two adjacent first light-emitting units 20 in the same pixel column 201 is the same as that of two adjacent pixel columns. The distances between two adjacent first light emitting units 20 in 201 are equal. Exemplarily, FIG. 3 shows a schematic structural diagram of a display panel in which the vertical projection shape of the first light emitting unit 20 is an ellipse. That is to say, the plurality of first light emitting units 20 are arranged in a p×q array.

In the p×q array of first light emitting units 20 , the second light emitting units 30 are disposed in the gaps between four adjacent first light emitting units 20 . Wherein, as shown in dotted line boxes in FIG. 1 and FIG. 3 , four adjacent first light emitting units 20 are arranged in a 2×2 array 200 . That is to say, a second light-emitting unit 30 is arranged in the middle of the 2×2 array 200 of each first light-emitting unit 20 to increase the brightness of the display picture when the display panel displays a white picture.

Optionally, FIG. 4 is a schematic top view structural diagram of another display panel provided by an embodiment of the present invention. Based on the above embodiments, as shown in FIG. 4 , the second light emitting unit 30 is cross-shaped; the second light emitting unit 30 includes four corners 31 , and each corner 31 faces a first light emitting unit 20 .

The corner portion 31 is arc-shaped, and the curvature of the corner portion 31 is the same as that of the edge of the first light-emitting unit 20 facing it.

Specifically, since the second light-emitting unit 30 is arranged in the middle gap of the 2×2 array 200 of the first light-emitting unit 20, the second light-emitting unit 30 can be arranged in a cross shape to make full use of the space between four adjacent first light-emitting units 20. The arrangement gap increases the area of the second light emitting unit 30, thereby improving the brightness of the white display screen.

Four corners 31 are provided at the included angles of the cross-shaped second light emitting unit 30 , and the corners 31 are arranged in an arc shape. Each corner portion 31 is directly opposite to one first light emitting unit 20 in the 2×2 array 200 , and there is a certain distance between the corner portion 31 and the first light emitting unit 20 . The curvature of the arc-shaped corner portion 31 is the same as the curvature of the edge of the first light-emitting unit 20 facing it. For example, as shown in FIG. The curvature of 31 is the same as that of the first light emitting unit 20 . If the first light emitting unit 20 is elliptical, the curvature of the corner portion 31 of the second light emitting unit 30 is the same as the curvature of the edge portion of the first light emitting unit 20 facing it. The corner portion 31 is set in an arc shape, which further increases the area of each second light-emitting unit 30 on the premise that the precision of the manufacturing process can be realized, thereby effectively improving the brightness of the display panel when displaying a white picture.

On the basis of the above embodiments, as shown in FIG. 5 , the plurality of first light emitting units 20 include a plurality of pixel rows 202, and in each pixel row 202, a plurality of first light emitting units 20 are arranged along the second direction X. , each pixel row 202 is arranged along the first direction Y, and each first light-emitting unit 20 is disposed between two adjacent first light-emitting units 20 in an adjacent pixel row 202; the second light-emitting unit 30 is disposed between adjacent between the three first light-emitting units 20.

Specifically, on the substrate 10, the plurality of first light emitting units 20 may also include a plurality of pixel rows 202, and the plurality of pixel rows 202 are arranged in sequence along the first direction Y. In each pixel row 202 , a plurality of first light emitting units 20 are arranged along the second direction X. As shown in FIG. The distance between the centers of two adjacent first light emitting units 20 in the same pixel row 202 is equal to the distance between the centers of circles of adjacent first light emitting units 20 in adjacent pixel rows 202, that is to say, in one pixel row 202 One first light emitting unit 20 and two adjacent first light emitting units 20 in an adjacent pixel row 202 are arranged to form an equilateral triangle. The second light-emitting unit 30 is arranged in the gap between three adjacent first light-emitting units 20 arranged in an equilateral triangle, making full use of the gap between the first light-emitting units 20 arranged in different arrangements, and additionally setting The white light emitting unit is used to increase the display brightness when the display panel displays a white picture.

Specifically, since the second light emitting unit 30 can also be arranged in the gap between three adjacent first light emitting units 20 arranged in an equilateral triangle, the second light emitting unit 30 can also be arranged in a triangular shape.

The second light emitting unit 30 has three sides 32 , and each side 32 is opposite to a first light emitting unit 20 . On the premise that the accuracy of the manufacturing process can be realized, in order to increase the area of the second light-emitting unit 30, the three sides 32 of the second light-emitting unit 30 are set in an arc shape, and the curvature of the arc-shaped sides 32 is the same as The edge curvatures of the facing first light emitting units 20 are the same. Designing the shape of the second light-emitting unit 30 in this way can increase the area of the second light-emitting unit 30 under the condition that the manufacturing process reaches the maximum precision, thereby improving the display brightness of the white screen.

The three first light emitting units 20 arranged in an equilateral triangle in two adjacent pixel rows 202 have different light emitting colors. For example, referring to FIG. 8 , the three adjacent first light emitting units 20 in the dotted line frame respectively include a first color light emitting unit 23 , a second color light emitting unit 24 and a third color light emitting unit 25 . That is to say, the light emitting colors of each first light emitting unit 20 adjacent to the same second light emitting unit 30 include the first color light emitting unit 23 , the second color light emitting unit 24 and the third color light emitting unit 25 .

The embodiment of the present invention also provides a display panel driving method. The display panel driving method is used to drive the display panels described in the above-mentioned embodiments. The display panel driving method includes:

When displaying a white picture, a driving signal is output to each of the first light emitting units and each of the second light emitting units to drive the first light emitting units and the second light emitting units to emit light.

Specifically, when the display panel displays a white picture, the first light emitting units of different light emitting colors are all driven to emit light, so that the display panel displays a white picture. At the same time, all the second light-emitting units are driven to emit light, so as to supplement the attenuated brightness of the white light emitted by the first light-emitting units after passing through the color filter layer, and improve the display brightness of the display panel.

When a non-white picture is displayed, a driving signal is output to the first light emitting unit, and only the first light emitting unit is driven to emit light.

Specifically, when the display panel displays a non-white solid-color image, a driving signal is sent to some of the first light emitting units to drive some of the first light emitting units to emit light without driving the second light emitting units to emit light. For example, when the display panel displays a red picture, only send a driving signal to the light emitting unit of the first color to drive the light emitting unit of the first color to emit red light; when the display panel displays a green picture, only send a driving signal to the light emitting unit of the second color signal to drive the light-emitting unit of the second color to emit green light; when the display panel displays a blue picture, it only sends a driving signal to the light-emitting unit of the third color to drive the light-emitting unit of the third color to emit blue light. Since the first light-emitting unit is set in a circular or elliptical shape, when displaying a non-white solid-color picture, the light emitted by the corresponding first light-emitting unit is not easy to be emitted by the color filter layer arranged directly above the other first light-emitting units, thereby effectively reducing the The possibility of light leakage is eliminated, and the display effect when the display panel is observed at a larger oblique viewing angle is improved.

The embodiment of the present invention also provides a display device. FIG. 9 is a schematic structural diagram of a display device provided by an embodiment of the present invention. As shown in FIG. 9 , the display device includes the display panel provided by the above-mentioned embodiments. The display device may include a panel of a mobile phone, a panel of a tablet, and the like. Wherein, the display panel included in the display device is provided with a plurality of first light emitting units and a plurality of second light emitting units on a substrate. Wherein, the first light-emitting unit includes a white light-emitting structure and a color filter layer, and the shape of the vertical projection of the first light-emitting unit is a circle or an ellipse to increase the distance between two adjacent first light-emitting units, thereby Reduces the possibility of light leakage from display panels. The second light-emitting unit includes a white light-emitting structure, and the second light-emitting unit is arranged in the gap between n adjacent first light-emitting units, so that when the display panel displays a white picture, each of the first light-emitting unit and the second light-emitting unit emits light , so as to effectively increase the brightness of the display screen and improve the display effect.

The above specific implementation methods do not constitute a limitation to the protection scope of the present invention. It should be apparent to those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made depending on design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
