Description

Technical Field

[0001] The utility model relates to the field of display technology, and in particular to a pixel arrangement structure, a display panel and a display device. Background Art

[0002] Micro LED display technology is a technology that integrates traditional LEDs into micron-level spacing LED arrays to achieve ultra-high resolution display effects. Micro-LED has the characteristics of self-luminescence. Compared with OLED and LCD displays, Micro-LED colors are easier to accurately adjust, have longer luminous life, higher brightness and contrast, and are thinner and more energy-saving. Due to its high density, small size, and ultra-high pixel characteristics, Micro-LED will become the most promising new generation of revolutionary display technology in the future. However, the existing Micro LED red light quantum efficiency (EQE) is lower than that of blue and green light, resulting in the red light chip emitting light intensity about 1 / 3 to 2 / 3 lower than that of blue and green light, making the white screen blue-green after the Micro LED three-color transfer, and the pure white display effect is not good. Utility Model Content

[0003] The purpose of the utility model is to provide a pixel arrangement structure, a display panel and a display device to realize compensation for the brightness of red light.

[0004] The utility model is achieved in this way:

[0005] In a first aspect, the present scheme provides a pixel arrangement structure, comprising: a plurality of LED pixel groups arranged in an array, wherein each of the LED pixel groups comprises at least two LED pixel units and a compensation pixel; the at least two LED pixel units are arranged longitudinally at a predetermined distance and each of the LED pixel units comprises at least one red sub-pixel, one green sub-pixel and one blue sub-pixel; the light emitting color of the compensation pixel is red, and the compensation pixel is arranged adjacent to the red sub-pixel in the LED pixel unit, and is located on the central symmetry axis of the red sub-pixel in the at least two LED pixel units.

[0006] By arranging a compensation pixel with a red light output color next to the red sub-pixel of the LED pixel unit, compensation for the red light emission brightness is achieved.

[0007] Furthermore, the area of ​​the compensation pixel is larger than the area of ​​the red sub-pixel.

[0008] By increasing the area of ​​the compensation pixel, a better red light compensation effect can be achieved.

[0009] Furthermore, the area of ​​the compensation pixel is twice the area of ​​the red sub-pixel.

[0010] By setting the area of ​​the compensation pixel to twice the area of ​​the red sub-pixel, a better compensation effect can be achieved.

[0011] Furthermore, at least one red sub-pixel, one green sub-pixel and one blue sub-pixel included in the LED pixel unit are all platform-type flip-chip structures.

[0012] By choosing a platform flip-chip structure, sub-pixels are easy to bond and arrange.

[0013] Furthermore, the light-emitting surfaces of at least one red sub-pixel, one green sub-pixel and one blue sub-pixel included in the adjacent longitudinally arranged LED pixel units are arranged at a first distance, and the non-light-emitting surfaces are arranged at a second distance, and the first distance is twice the second distance.

[0014] Since the sub-pixel is a platform flip-chip structure, it has a light-emitting surface and a non-light-emitting surface. The light-emitting surfaces are spaced apart by a larger first distance, and the non-light-emitting surfaces are spaced apart by a smaller second distance, so that the overall pixel arrangement structure emits light more uniformly and the visual effect is better.

[0015] Further, when only one red sub-pixel in the at least two LED pixel units is powered on and emits light, the compensation pixel is powered on and emits light to compensate for the light emission of the red sub-pixel; when each of the red sub-pixels in the at least two LED pixel units is powered on and emits light, the compensation pixel is not powered on and emits light to stop compensating for the light emission of the red sub-pixel.

[0016] When only one red sub-pixel in adjacent vertically arranged LED pixel units is powered on and emits light, in order to compensate for its light brightness, the compensation pixel is turned on and emitted light. However, if multiple red sub-pixels are powered on and emit light, no compensation pixel is required for compensation.

[0017] Furthermore, each of the LED pixel groups further includes a driver IC, and the driver IC is used to drive and control each sub-pixel included in the LED pixel unit.

[0018] By providing a separate driving IC for each LED pixel group, each LED pixel group can be driven and controlled independently.

[0019] Furthermore, when only one red sub-pixel in the at least two LED pixel units is powered on and emits light, the compensation pixel is powered on and emits light to compensate for the light output of the red sub-pixel; when each of the red sub-pixels in the at least two LED pixel units is powered on and emits light, the compensation pixel is powered on and emits light, and the driver IC controls the brightness of the compensation pixel.

[0020] The brightness of the compensation pixel is adjusted by the driver IC, and the brightness of the red sub-pixel in the LED pixel unit can be compensated as needed.

[0021] In a second aspect, the present solution provides a display panel, comprising a display backplane and a packaging panel, the display backplane being provided with the pixel arrangement structure, and the packaging panel being used to package the display backplane.

[0022] By arranging the pixels on the display panel according to the above pixel arrangement structure, a display panel with better display effect can be obtained.

[0023] In a third aspect, the present solution provides a display device, comprising a controller and the display panel, wherein the controller is used to drive the display panel for display.

[0024] The display device is a terminal electronic device equipped with a display panel. Since it is equipped with a display panel with better display effects, the overall user experience is better.

[0025] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a pixel arrangement structure, a display panel and a display device, the display device is equipped with a display panel, and a pixel arrangement structure is bonded to the display panel, the pixel arrangement structure includes: a plurality of LED pixel groups arranged in an array, each LED pixel group includes at least two LED pixel units and a compensation pixel, each LED pixel unit includes at least one red sub-pixel, one green sub-pixel and one blue sub-pixel; the compensation pixel has a red light output color, is arranged next to the red sub-pixel of the LED pixel unit and is located on the central symmetry axis of the red sub-pixel in the at least two LED pixel units, so as to perform brightness compensation for the red light output in real time according to the display state of the red sub-pixel in the LED pixel unit.

[0034] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0035] Please refer to Figure 1, is a schematic diagram of a pixel arrangement structure 100 provided by an embodiment of the present utility model, and the pixel arrangement structure 100 includes:

[0036] The plurality of LED pixel groups 110 arranged in an array are further configured as follows: Figure 2 , is a schematic diagram of the structure of an LED pixel group 110 provided by an embodiment of the utility model, each LED pixel group 110 includes at least two LED pixel units 111 and a compensation pixel 112. The at least two LED pixel units 111 are arranged at a predetermined distance in the longitudinal direction, and each LED pixel unit 111 includes at least one red sub-pixel (R), one green sub-pixel (G) and one blue sub-pixel (B). The light emitting color of the compensation pixel 112 is red, and it is arranged adjacent to the red sub-pixel in the LED pixel unit 111, and is located on the central symmetry axis of the red sub-pixels of at least two LED pixel units 111, so as to compensate the red light brightness of the red sub-pixel.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, the area of ​​the compensation pixel 112 is larger than the area of ​​any red sub-pixel in the LED pixel unit 111. The larger the area, the stronger the emitted light, so that the compensation pixel 112 can better compensate for the light emission effect of the red sub-pixel. Preferably, the area of ​​the compensation pixel 112 can be twice the area of ​​the red sub-pixel, so that the light emission intensity of the compensation pixel 112 is also twice the light emission brightness of a single red sub-pixel, thereby achieving a better red light compensation effect.

[0038] Please refer to Figure 3 As shown in the figure, it is a schematic diagram of a platform flip-chip structure provided by an embodiment of the utility model. It should be noted that at least one red sub-pixel, one green sub-pixel and one blue sub-pixel included in the LED pixel unit 111 are all of the platform flip-chip structure. That is to say, each sub-pixel includes at least an N-type semiconductor layer, a quantum well layer and a P-type semiconductor layer, wherein one side of the N-type semiconductor layer is arranged in a platform, and an N electrode is formed at the platform to be directly electrically connected to the N-type semiconductor layer, and a P electrode is formed at the P-type semiconductor layer. After power is turned on, the electrons and holes generated by the N-type semiconductor layer and the P-type semiconductor layer recombine at the quantum well layer to emit light of different colors, and then as shown in FIG. Figure 3 The left side shows the luminous surface. Figure 3 The right side is the non-luminous side.

[0039] For further information, please refer to Figure 1Based on the structural design of the above sub-pixels, in order to improve the visual effect and optimize the display effect, the present solution also improves the spacing distance and arrangement between the multiple LED pixel groups 110. Specifically, in the same LED pixel group 110, the light-emitting surfaces of at least one red sub-pixel, one green sub-pixel and one blue sub-pixel (i.e., the side where the P electrode is set, marked with P in the figure) of at least two adjacent LED pixel units 111 arranged vertically are arranged at a first distance, and the first distance is as follows: Figure 1 The non-luminous surfaces of adjacent LED pixel groups 110 are arranged at a second distance, and the second distance is as shown in FIG. Figure 1 The first distance 2X is twice the second distance X. Since the side where the N electrode is located is a non-luminous surface (marked with N in the figure), the spacing distance between the non-luminous surfaces of adjacent sub-pixels is the smaller second distance, and the spacing distance between the luminous surfaces is the larger first distance, so that the spacing distances of all sub-pixels on the panel can be balanced, so that the overall visual effect is better, and there will be no problem that the sub-pixels are arranged compactly in one place and sparsely in another place, making the overall visual effect too bright or too dark in part, or even causing color deviation and other problems.

[0040] In actual operation, when only one red sub-pixel in at least two LED pixel units 111 is powered on and emits light, the compensation pixel 112 will also be powered on and emit light to compensate for the light output of the red sub-pixel; when each red sub-pixel in at least two LED pixel units 111 is powered on and emits light, the compensation pixel 112 is not powered on and emits light. At this time, multiple red sub-pixels emit light at the same time, and their brightness is sufficient, so there is no need to turn on the compensation pixel 112 to compensate for the red light brightness.

[0041] Please refer to Figure 4 , is a schematic structural diagram of another pixel arrangement structure 200 provided in an embodiment of the present utility model. Compared with the pixel arrangement structure 100, the pixel arrangement structure 200 is additionally provided with a driver IC (ie, the Driver IC shown in the figure), and the other arrangement structures are arranged in the same manner.

[0042] That is, each LED pixel group 110 further includes a driver IC, and the driver IC is used to drive and control the LED pixel unit 111 provided in the LED pixel group 110 .

[0043] Specifically, when only one red sub-pixel in at least two LED pixel units 111 is powered on to emit light, the compensation pixel 112 is powered on to emit light to compensate for the light output of the red sub-pixel;

[0044] When each red sub-pixel in at least two LED pixel units 111 is powered on to emit light, the compensation pixel 112 in the pixel arrangement structure 100 does not need to be powered on to emit light for red light compensation. However, after adding a driver IC, that is, in the pixel arrangement structure 200, the compensation pixel 112 needs to be powered on to emit light. At this time, the driver IC will flexibly adjust the brightness of the compensation pixel 112 according to demand to match the current visual effect requirements. Compared with the control method in the pixel arrangement structure 100, adding a driver IC makes the control more flexible and more adaptable to the visual effect requirements in different environments.

[0045] Furthermore, the embodiment of the utility model also provides a display panel, which includes a display backplane and a packaging panel, and the display backplane is provided with the above-mentioned pixel arrangement structure 100 or pixel arrangement structure 200. After bonding is completed, the packaging panel is used to package the display backplane. The display panel can be a display screen of various sizes, such as a mobile phone display screen, a computer display screen, a TV display screen, etc., because it better compensates for the light emission effect of red light, so that the overall display panel has a better visual effect.

[0046] Furthermore, the embodiment of the utility model also provides a display device, which includes a controller and the above-mentioned display panel, and the controller is used to drive the display panel to display. The display device can be but is not limited to terminal electronic devices such as mobile phones, computers, and televisions.

[0047] In summary, the utility model provides a pixel arrangement structure, a display panel and a display device, the display device is equipped with a display panel, and a pixel arrangement structure is bonded to the display panel, the pixel arrangement structure includes: a plurality of LED pixel groups arranged in an array, each LED pixel group includes at least two LED pixel units and a compensation pixel, each LED pixel unit includes at least one red sub-pixel, one green sub-pixel and one blue sub-pixel; the compensation pixel has a red light output color, is arranged next to the red sub-pixel of the LED pixel unit and is located on the central symmetry axis of the red sub-pixel of the at least two LED pixel units, so as to perform brightness compensation for the red light in real time according to the display state of the red sub-pixel in the LED pixel unit.
