Description

Technical Field

[0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display module and a display panel. Background Art

[0002] With the development of LED display screens, people's requirements for the display effect of display screens are getting higher and higher. For LED display screens using the chip-on-board (COB) method, as the size of LED wafers gradually decreases, not only the upper surface where photons are emitted needs to be considered, but also the side surfaces where photons are emitted need to be considered. Among the pixels of each unit board on the LED display screen, since red wafers and blue / green wafers use different material systems. For example, red wafers use the AlGaInP-based system, and blue wafers and green wafers use the InGaN-based system. Therefore, when the light emission angle is relatively large, the light extraction efficiency of blue wafers and green wafers is greater than that of red wafers. This will cause color deviation after light mixing at the longitudinal edges of the unit board, resulting in side light leakage, and it is easy to cause abnormal light color at the longitudinal splicing positions between unit boards.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily need to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0039] An embodiment of the present invention provides a display module. Figure 1 It is a schematic diagram of the structure of a display module provided by an embodiment of the present invention. As Figure 1 shown, the display module includes: a substrate 10 and a plurality of pixels 20.

[0040] The substrate 10 includes at least one first edge 11; pixels 20 are disposed on the substrate 10, and a plurality of pixels 20 are arranged in an array; each pixel 20 includes a red light chip 21, a green light chip 22, and a blue light chip 23.

[0041] In a column of pixels 20 adjacent to the first edge 11 of the substrate 10, the red light chip 21 is arranged closer to the first edge 11 of the substrate 10 than the green light chip 22 and the blue light chip 23.

[0042] Specifically, the substrate 10 in the display module is used to carry each pixel 20 and provide a control signal. The control signal is transmitted to the corresponding pixel 20 to control each pixel 20 to emit light according to a certain rule, thereby realizing the image display of the display panel. A plurality of pixels 20 are arranged on the substrate 10 in an array. As the size of the pixel 20 gradually decreases, the number of pixels 20 arranged on the substrate 10 per unit area increases, thereby improving the display effect of the display panel and making the image display clearer.

[0043] The substrate 10 includes at least one first edge 11. Exemplarily, the substrate 10 may include two first edges 11, that is, both the left edge and the right edge of the substrate 10 can be used as the first edge 11. Figure 1 The case where the right edge of the substrate 10 is used as the first edge 11 is shown. Each pixel 20 may include wafers of multiple different light colors. Exemplarily, Figure 1 It is shown that the pixel 20 includes a red light chip 21, a green light chip 22, and a blue light chip 23. After the red light emitted by the red light chip 21, the green light emitted by the green light chip 22, and the blue light emitted by the blue light chip 23 are mixed, white light can be emitted from the light-emitting surface facing the pixel 20.

[0044] In a column of pixels 20 adjacent to the first edge 11, the red light chip 21 is arranged at a position closer to the first edge 11 than the green light chip 22 and the blue light chip 23, so that the red light emitted by the red light chip 21 from the first edge 11 is more than the green light emitted by the green light chip 22 from the first edge 11 and the blue light emitted by the blue light chip 23 from the first edge 11. Therefore, the light extraction efficiency of the red light emitted by the red light chip 21 at the first edge 11 is improved, the red light brightness in each pixel 20 adjacent to the first edge 11 is increased, thereby improving the color deviation phenomenon at the first edge 11 of the substrate 10 in the display module, improving the light color consistency of the display panel, and improving the display effect.

[0045] In the display module provided by the technical solution of this embodiment, the substrate includes at least one first edge. By arranging a plurality of pixels in an array on the substrate, each pixel includes a red light chip, a green light chip, and a blue light chip. In a column of pixels adjacent to the first edge of the substrate, the red light chip is arranged closer to the first edge than the green light chip and the blue light chip, so that the red light emitted by the red light chip is more than the green light emitted by the green light chip and the blue light emitted by the blue light chip. The display module provided by this embodiment can effectively improve the color deviation phenomenon at the splicing of the first edge of the display module, improve the light color consistency between the splicing of the first edge of the display module and the entire display panel, and achieve a good display effect.

[0046] Optionally, Figure 2 is a schematic structural diagram of another display module provided by an embodiment of the present invention, Figure 3 is a schematic diagram of the chip arrangement inside a pixel provided by an embodiment of the present invention, Figure 4 is another schematic diagram of the chip arrangement inside a pixel provided by an embodiment of the present invention. On the basis of the above embodiment, in combination with Figures 1 - 4 , in a column of pixels 20 adjacent to the first edge 11: the red light chip 21, the green light chip 22, and the blue light chip 23 in each pixel 20 are arranged in the order of red light chip 21 - green light chip 22 - blue light chip 23 or red light chip 21 - blue light chip 23 - green light chip 22 along the direction parallel to the first edge 11; or, the red light chip 21 in each pixel 20 is arranged between the green light chip 22 and the blue light chip 23.

[0047] Specifically, taking Figure 2 the right edge of the display module substrate 10 shown as the first edge 11 as an example, except for a column of pixels 20 adjacent to the first edge 11, in other pixels 20 arranged on the substrate 10, the red light chip 21, the green light chip 22, and the blue light chip 23 are arranged in sequence along the direction parallel to the first edge 11, and the distances from them to the first edge 11 are the same. The light emitted by each chip is mixed to form white light and is emitted from the front light-emitting surface.

[0048] For a column of pixels 20 adjacent to the first edge 11, the divergence angle of the emitted light is relatively large. Due to the different material systems of each chip, when the red light chip 21 emits light at a large angle, the light extraction efficiency is lower than that of the green light chip 22 and the blue light chip 23, resulting in a color deviation phenomenon in the column of pixels 20 adjacent to the first edge 11. As Figure 1 shown, by reducing the distance between the red light chip 21 and the first edge 11 and arranging the red light chip 21 closer to the first edge 11 than the green light chip 22 and the blue light chip 23, the emitted light of the red light chip 21 is increased, thereby improving the light extraction efficiency of the red light chip 21 and improving the color deviation phenomenon at the splicing of the first edge 11. In combination with Figure 1And Figure 3 For the arrangement order of the green light chip 22 and the blue light chip 23, there is no limitation here. According to the order of the red light chip 21 - green light chip 22 - blue light chip 23 or the order of the red light chip 21 - blue light chip 23 - green light chip 22, it is possible to improve the side light overflow phenomenon at the splicing position of the first edge 11, so that the light emitted from the splicing position is also white light. And according to any one of the above two arrangement orders, the red light chip 21 can be close to the edge perpendicular to the first edge 11, so as to ensure the light color consistency at the splicing position of the edge perpendicular to the first edge 11.

[0049] Combined with Figure 2 and Figure 4 It is also possible to arrange the red light chip 21 between the green light chip 22 and the blue light chip 23, and the red light chip 21 is arranged closer to the first edge 11 compared with the green light chip 22 and the blue light chip 23. With such an arrangement, the light color consistency of each pixel 20 in a column of pixels 20 adjacent to the first edge 11 can be improved, so that the light emitted from each pixel 20 is white light, thereby better improving the color deviation phenomenon at the splicing position of the first edge 11. As Figure 2 and Figure 4 For the green light chip 22 and the blue light chip 23, their arrangement positions can be interchanged, that is, the chips in each pixel 20 can be arranged in the order of green light chip 22 - red light chip 21 - blue light chip 23, or in the order of blue light chip 23 - red light chip 21 - green light chip 22. Both of the two chip arrangement orders can make each pixel 20 achieve light color consistency.

[0050] It should be noted that if the left edge of the substrate 10 is used as the first edge 11, the red light chip 21 is arranged close to the left first edge 11, and the arrangement method is the same as when the right edge is used as the first edge 11, which will not be elaborated here.

[0051] Optionally, on the basis of the above embodiments, each pixel 20 further includes: a white light chip 24.

[0052] Specifically, for each pixel 20, the white light chip 24 is used to adjust the white balance, which is beneficial to reducing the influence of side light overflow. And adding the white light chip 24 in each pixel 20 can improve the overall brightness of the display panel.

[0053] Optionally, on the basis of the above embodiments, in each pixel 20, the red light chip 21 and the white light chip 24 are arranged adjacent to each other, and in the same pixel 20, the red light chip 21 and the white light chip 24 are closer to the first edge 11 compared with the green light chip 22 and the blue light chip 23.

[0054] Specifically, in each pixel 20, the red light chip 21 is disposed at a position close to the first edge 11, and the green light chip 22 and the blue light chip 23 are disposed at positions relatively far from the first edge 11, which can reduce the divergence angle of the light emitted by the red light chip 21, thereby improving the light extraction efficiency of the red light chip 21. In addition, the white light chip 24 is disposed adjacent to the red light chip 21 to achieve the improvement of the color deviation phenomenon at the side edge of the display module by adjusting the white balance, and at the same time improve the brightness of the entire display panel. The arrangement positions of the green light chip 22 and the blue light chip 23 can be interchanged, which does not affect the improvement effect of the color deviation phenomenon at the splicing position of the first edge 11 of the display module, and is not limited herein.

[0055] When the pixel 20 includes wafers of four light colors, namely the red light chip 21, the green light chip 22, the blue light chip 23, and the white light chip 24, there are also various arrangement methods and arrangement orders of the wafers in each pixel 20. The following embodiments will specifically illustrate the selectable wafer arrangement methods and arrangement orders.

[0056] Optionally, Figure 5 is a schematic structural diagram of another display module provided by an embodiment of the present invention. On the basis of the above embodiments, as Figure 5 shown, in each pixel 20, the red light chip 21, the green light chip 22, the blue light chip 23, and the white light chip 24 are arranged in a "hui" shape.

[0057] Specifically, taking Figure 5 the right edge of the substrate 10 in the shown display module as the first edge 11 as an example, the wafers of the four light colors can be arranged in a "hui" shape, and the red light chip 21 and the white light chip 24 are arranged on both sides of the "hui" shape close to the first edge 11, which can effectively improve the color deviation phenomenon at the splicing position of the first edge 11 of the display module.

[0058] Exemplarily, Figure 6 is a schematic diagram of another wafer arrangement method in a pixel provided by an embodiment of the present invention. Combining Figure 5 and Figure 6 , starting from a wafer parallel to the first edge 11 in the "hui" shape in the clockwise direction, the arrangement order of the wafers in the pixel 20 can be the white light chip 24 - the green light chip 22 - the blue light chip 23 - the red light chip 21, or the red light chip 21 - the green light chip 22 - the blue light chip 23 - the white light chip 24. That is to say, it only needs to satisfy that the red light chip 21 and the white light chip 24 are arranged on two side edges of the "hui" shape close to the first edge 11, and the green light chip 22 and the blue light chip 23 can be arbitrarily arranged at positions other than the red light chip 21 and the white light chip 24. The arrangement methods of wafers of different light colors are not limited to the methods provided in this embodiment, and other wafer arrangement methods that meet the conditions are also included in this embodiment.

[0059] It should be noted that if the left edge of the substrate 10 is used as the first edge 11, the red light chips 21 and the white light chips 24 are arranged close to the left first edge 11, and the arrangement method is the same as that when the right edge is used as the first edge 11, which will not be elaborated here.

[0060] Optionally, Figure 7 is a schematic structural diagram of another display module provided by an embodiment of the present invention. On the basis of the above embodiments, as Figure 7 shown, in each pixel 20, the red light chips 21, the green light chips 22, the blue light chips 23, and the white light chips 24 are arranged in a 2×2 array, and the red light chips 21 and the white light chips 24 are arranged in sequence along a direction parallel to the extension direction of the first edge 11.

[0061] Specifically, taking Figure 7 the right edge in the display module substrate 10 shown as the first edge 11 as an example, in the pixel 20 including four chips, the chips can also be arranged in a 2×2 array. In the 2×2 array, the red light chips 21 and the white light chips 24 need to be arranged in a column close to the first edge 11, and the green light chips 22 and the blue light chips 23 are arranged in a column far from the first edge 11, so as to reduce the divergence angle of the light emitted by the red light chips 21, improve the light extraction efficiency of the red light chips 21, and adjust the white balance through the white light chips 24, improve the side light leakage phenomenon at the splicing position of the first edge 11 of the display module, and improve the display brightness of the display module.

[0062] Optionally, on the basis of the above embodiments, continue to refer to Figure 7 , there is the same preset angle θ between the extension directions of the red light chips 21, the green light chips 22, the blue light chips 23, and the white light chips 24 and the extension direction of the first edge 11; wherein, the preset angle θ is less than 90°.

[0063] Specifically, by setting a certain preset angle θ between the extension direction of each chip and the extension direction of the first edge 11, and 0° < θ < 90°, the light superposition or occlusion generated between the chips in the direction perpendicular to the first edge 11 can be reduced to a certain extent, so that no black lines will appear when the user observes from the direction perpendicular to the first edge 11 of the display module, and the display effect is improved. Preferably, as Figure 7 shown, the preset angle θ is selected as 45°, and a better display effect can be obtained.

[0064] For the arrangement order of the chips in each pixel 20, in a column close to the first edge 11, the arrangement orders of the red light chips 21 and the white light chips 24 can be interchanged with each other, and the arrangement orders of the green light chips 22 and the blue light chips 23 can also be interchanged with each other, and the color deviation phenomenon at the splicing position of the first edge 11 can be improved, and the effect of improving the light color consistency can be achieved. Exemplarily, Figure 8It is a schematic diagram of another arrangement of wafers in a pixel provided by an embodiment of the present invention. Figure 9 It is a schematic diagram of another arrangement of wafers in a pixel provided by an embodiment of the present invention. As Figures 7 - 9 shown, the wafers in each pixel 20 can be arranged in a clockwise or counterclockwise order from the direction close to the first edge 11 to the direction away from the first edge 11. For example, they can be arranged in the order of red light wafer 21 - white light wafer 24 - green light wafer 22 - blue light wafer 23, or in the order of white light wafer 24 - red light wafer 21 - green light wafer 22 - blue light wafer 23 or in the order of white light wafer 24 - red light wafer 21 - blue light wafer 23 - green light wafer 22, or also in the order of red light wafer 21 - white light wafer 24 - blue light wafer 23 - green light wafer 22. The arrangement methods of wafers of different light colors are not limited to the methods provided in this embodiment, and other wafer arrangement methods that meet the conditions are also included in this embodiment.

[0065] It should be noted that if the left edge of the substrate 10 is used as the first edge 11, the red light wafer 21 and the white light wafer 24 are arranged at positions close to the left first edge 11, and the arrangement method is the same as when the right edge is used as the first edge 11, which will not be elaborated here.

[0066] Optionally, Figure 10 It is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. On the basis of the above embodiments, as Figure 10 shown, in each pixel 20, the red light wafer 21 and the white light wafer 24 are arranged in sequence along a direction perpendicular to the extension direction of the first edge 11, and the red light wafer 21 is closer to the first edge 11 than the white light wafer 24.

[0067] Along the extension direction of the first edge 11, the green light wafer 22 and the blue light wafer 23 are located on both sides of the red light wafer 21 and the white light wafer 24.

[0068] Specifically, taking Figure 10 the right edge in the display module substrate 10 shown as the first edge 11 as an example, in a pixel 20 containing four wafers, the wafers can also be arranged in a 1 - 2 - 1 manner, that is, the red light wafer 21 and the white light wafer 24 are arranged in sequence along a direction perpendicular to the first edge 11, and the green light wafer 22 and the blue light wafer 23 are respectively arranged on both sides of the red light wafer 21 and the white light wafer 24 along the extension direction of the first edge 11. Therefore, the red light wafer 21 is closer to the first edge 11 than the green light wafer 22 and the blue light wafer 23, thereby improving the color deviation phenomenon at the splicing position of the first edge 11 of the substrate 10 and improving the light color consistency within each pixel 20. Exemplarily, the green light wafer 22 and the blue light wafer 23 can be located on the perpendicular bisector of the line connecting the geometric centers of the red light wafer 21 and the white light wafer 24.

[0069] Optionally, based on the above embodiments, continue to refer to Figure 10 , the extending directions of the red light chip 21, the green light chip 22, the blue light chip 23 and the white light chip 24 are all perpendicular to the extending direction of the first edge 11.

[0070] Specifically, since the red light chip 21 and the white light chip 24 are arranged in sequence along the direction perpendicular to the first edge 11, and the extending directions of the red light chip 21 and the white light chip 24 are perpendicular to the extending direction of the first edge 11, but the white light chip 24 is used to adjust the white balance and improve the overall brightness of the display module, and has a relatively small impact on the color. Therefore, arranging the red light chip 21 and the white light chip 24 in sequence along the direction perpendicular to the first edge 11 can make the red light chip 21 closer to the first edge 11, and there will be no black line when the user observes from the direction perpendicular to the first edge 11 of the display module, improving the display effect.

[0071] In each pixel 20, exemplarily, Figure 11 is a schematic diagram of another arrangement of chips in a pixel provided by an embodiment of the present invention. As Figure 10 and Figure 11 shown, the positions of the green light chip 22 and the blue light chip 23 can be interchanged, which is not limited herein.

[0072] It should be noted that Figure 12 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention. If the left edge of the substrate 10 is used as the first edge 11, then as Figure 12 shown, the red light chip 21 is arranged at a position close to the left first edge 11, and the white light chip 24 is arranged at a position adjacent to the red light chip 21 along the direction perpendicular to the first edge 11, and the effect of improving the color deviation phenomenon of the left first edge 11 can also be achieved, improving the light color consistency of the display module.

[0073] An embodiment of the present invention further provides a display panel. Figure 13 is a schematic diagram of the structure of a display panel provided by an embodiment of the present invention. As Figure 13As shown, the display panel 02 includes a plurality of display modules 01 as described in any of the above embodiments, and the plurality of display modules 01 are spliced together. The display panel can be a mobile phone panel, an LED display screen, etc. Exemplarily, taking the display module 01 included in the display panel 02 where each pixel includes wafers of three light colors as an example, the display panel 02 will be described. In the display module 01 included in the display panel 02, among a column of pixels adjacent to the first edge 11 of the substrate 10, the red light wafer 21 is arranged closer to the first edge 11 than the green light wafer 22 and the blue light wafer 23, so that the divergence angle of the emitted light of the red light wafer 21 is smaller than the divergence angles of the emitted lights of the green light wafer 22 and the blue light wafer 23, thereby improving the color deviation phenomenon at the splicing position between the display modules 01 on the display panel 02, improving the light color consistency of the entire display panel 02, and enabling the entire display panel to have a good display effect.

[0074] The above specific embodiments do not constitute a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
