The embodiment of the invention provides a display module. Fig. 1 is a schematic structural diagram of a display module according to an embodiment of the present invention. As shown in fig. 1, the display module includes: a substrate 10 and a plurality of pixels 20.
The substrate 10 comprises at least one first edge 11; the pixels 20 are arranged on the substrate 10, and a plurality of pixels 20 are arranged in an array; each pixel 20 includes a red wafer 21, a green wafer 22, and a blue wafer 23.
In a column of pixels 20 adjacent to the first edge 11 of the substrate 10, the red wafer 21 is arranged closer to the first edge 11 of the substrate 10 than the green wafer 22 and the blue wafer 23.
Specifically, the substrate 10 in the display module is used for carrying each pixel 20 and providing a control signal, and the control signal is transmitted to the corresponding pixel 20 to control each pixel 20 to emit light according to a certain rule, thereby implementing image display of the display panel. A plurality of pixels 20 are disposed on the substrate 10, and the plurality of pixels 20 are arranged in an array on the substrate 10. As the size of the pixels 20 is gradually reduced, the number of the pixels 20 disposed on the substrate 10 per unit area is increased, thereby improving the display effect of the display panel and making the image display clearer.
The substrate 10 includes at least one first edge 11, and illustratively, the substrate 10 may include two first edges 11, i.e., both a left side edge and a right side edge of the substrate 10 may be the first edges 11, and fig. 1 shows a case where the right side edge of the substrate 10 is the first edge 11. Each pixel 20 may include a plurality of chips with different light colors, and fig. 1 shows that the pixel 20 includes a red chip 21, a green chip 22, and a blue chip 23, and after red light emitted from the red chip 21, green light emitted from the green chip 22, and blue light emitted from the blue chip 23 are mixed, white light can be emitted from the light emitting surface facing the pixel 20.
In a column of pixels 20 adjacent to the first edge 11, the red wafer 21 is disposed closer to the first edge 11 than the green wafer 22 and the blue wafer 23 so that more red light is emitted from the first edge 11 by the red wafer 21 than green light is emitted from the first edge 11 by the green wafer 22 and more blue light is emitted from the first edge 11 by the blue wafer 23. Therefore, the light extraction efficiency of the red light emitted by the red light wafer 21 at the first edge 11 is improved, and the red light brightness in each pixel 20 adjacent to the first edge 11 is increased, so that the color shift phenomenon at the first edge 11 of the substrate 10 in the display module is improved, the light color consistency of the display panel is improved, and the display effect is improved.
In the display module provided in the technical solution of this embodiment, the substrate includes at least one first edge. By arranging a plurality of pixels arranged in an array on a substrate, each pixel comprises a red light wafer, a green light wafer and a blue light wafer. In a column of pixels adjacent to the first edge of the substrate, the red light wafers are arranged closer to the first edge than the green light wafers and the blue light wafers, so that more red light is emitted by the red light wafers than green light emitted by the green light wafers and blue light emitted by the blue light wafers. The display module assembly that this embodiment provided can effectively improve the colour cast phenomenon of the first edge concatenation department of display module assembly, improves the first edge concatenation department of display module assembly and whole display panel's light color uniformity, reaches good display effect.
Optionally, fig. 2 is a schematic structural diagram of another display module according to an embodiment of the present invention, fig. 3 is a schematic wafer layout diagram inside a pixel according to an embodiment of the present invention, and fig. 4 is a schematic wafer layout diagram inside another pixel according to an embodiment of the present invention. On the basis of the above embodiment, with reference to fig. 1 to 4, in a column of pixels 20 adjacent to the first edge 11: the red light wafer 21, the green light wafer 22 and the blue light wafer 23 in each pixel 20 are sequentially arranged in the order of the red light wafer 21-the green light wafer 22-the blue light wafer 23 or the order of the red light wafer 21-the blue light wafer 23-the green light wafer 22 along the direction parallel to the first edge 11; alternatively, the red wafer 21 in each pixel 20 is disposed between the green wafer 22 and the blue wafer 23.
Specifically, taking the right edge of the display module substrate 10 shown in fig. 2 as the first edge 11 as an example, except for a row of pixels 20 adjacent to the first edge 11, among the other pixels 20 disposed on the substrate 10, the red light wafer 21, the green light wafer 22 and the blue light wafer 23 are sequentially arranged in a direction parallel to the first edge 11, and the distances from the first edge 11 are the same. The light rays emitted from each wafer are mixed to form white light, and the white light is emitted from the light emitting surface on the front side.
The divergence angle of the outgoing light is larger for the row of pixels 20 adjacent to the first edge 11, and due to the different material systems of the wafers, when the red light wafer 21 is outgoing at a large angle, the light outgoing efficiency is lower than that of the green light wafer 22 and the blue light wafer 23, so that the row of pixels 20 adjacent to the first edge 11 is prone to color shift. As shown in fig. 1, the distance between the red wafer 21 and the first edge 11 is reduced, and the red wafer 21 is disposed closer to the first edge 11 than the green wafer 22 and the blue wafer 23, so that the emergent light of the red wafer 21 is increased, thereby improving the light-emitting efficiency of the red wafer 21 and the color shift phenomenon at the joint of the first edge 11. With reference to fig. 1 and 3, the arrangement sequence of the green light wafer 22 and the blue light wafer 23 is not limited herein, and the side light overflow phenomenon at the joint of the first edge 11 can be improved according to the sequence of the red light wafer 21-the green light wafer 22-the blue light wafer 23 or the sequence of the red light wafer 21-the blue light wafer 23-the green light wafer 22, so that the light emitted from the joint is also white light. And according to any one of the two arrangement sequences, the red light wafer 21 can be close to the edge perpendicular to the first edge 11, so that the light color consistency of the edge splicing part perpendicular to the first edge 11 can be ensured.
With reference to fig. 2 and 4, the red wafer 21 may also be disposed between the green wafer 22 and the blue wafer 23, and the red wafer 21 is disposed closer to the first edge 11 than the green wafer 22 and the blue wafer 23. With this 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 by each pixel 20 is white light, and the color shift phenomenon at the joint of the first edge 11 is better improved. As shown in fig. 2 and 4, the arrangement positions of the green chip 22 and the blue chip 23 can be exchanged, that is, the chips in each pixel 20 can be arranged in the order of the green chip 22-the red chip 21-the blue chip 23, or in the order of the blue chip 23-the red chip 21-the green chip 22, and the arrangement order of the two chips can make each pixel 20 achieve the light color consistency.
It should be noted that, if the left edge of the substrate 10 is taken as the first edge 11, the red light emitting chips 21 are arranged at a position close to the left first edge 11 in the same manner as the right edge is taken as the first edge 11, which is not described herein again.
Optionally, on the basis of the above embodiments, each pixel 20 further includes: a white light chip 24.
Specifically, the white wafer 24 is used to adjust the white balance for each pixel 20, which is advantageous for reducing the influence of side spill light. And the addition of the white chip 24 in each pixel 20 can improve the overall brightness of the display panel.
Alternatively, on the basis of the above embodiments, in each pixel 20, the red wafer 21 and the white wafer 24 are arranged adjacently, and in the same pixel 20, the red wafer 21 and the white wafer 24 are closer to the first edge 11 than the green wafer 22 and the blue wafer 23.
Specifically, in each pixel 20, the red wafer 21 is disposed at a position close to the first edge 11, and the green wafer 22 and the blue wafer 23 are disposed at a position relatively far from the first edge 11, so that the divergence angle of the light emitted from the red wafer 21 can be reduced, thereby improving the light extraction efficiency of the red wafer 21. In addition, the white light wafer 24 is disposed adjacent to the red light wafer 21, so that the color shift phenomenon of the side edge of the display module is improved by adjusting the white balance, and the brightness of the whole display panel is improved. 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 cast phenomenon of the display module at the splicing position of the first edge 11, and is not limited herein.
When the pixels 20 include red light chips 21, green light chips 22, blue light chips 23, and white light chips 24, there are various arrangements and orders of the chips in each pixel 20, and the following embodiments will specifically describe the arrangement and order of the chips that can be selected.
Optionally, fig. 5 is a schematic structural diagram of another display module according to an embodiment of the present invention. Based on the above embodiments, as shown in fig. 5, 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 shape of a Chinese character 'hui'.
Specifically, taking the right edge of the substrate 10 in the display module shown in fig. 5 as the first edge 11 as an example, the four light-colored chips may be arranged in a "loop" shape, and the red light chip 21 and the white light chip 24 are arranged on two sides of the "loop" shape close to the first edge 11, so as to effectively improve the color shift phenomenon at the joint of the first edge 11 of the display module.
Exemplarily, fig. 6 is a schematic diagram of a wafer arrangement in another pixel provided by the embodiment of the present invention. Referring to fig. 5 and 6, the arrangement order of the wafers in the pixel 20 may be white light wafer 24-green light wafer 22-blue light wafer 23-red light wafer 21, or red light wafer 21-green light wafer 22-blue light wafer 23-white light wafer 24, from a wafer parallel to the first edge 11 in the "return" shape in a clockwise direction. That is, it is only necessary to arrange the red wafer 21 and the white wafer 24 at both sides of the "return" shape near the first edge 11, and the green wafer 22 and the blue wafer 23 may be arranged at arbitrary positions outside the red wafer 21 and the white wafer 24. The arrangement of the wafers with different light colors is not limited to the arrangement provided in this embodiment, and other wafer arrangements satisfying the conditions are also included in this embodiment.
It should be noted that, if the left edge of the substrate 10 is taken as the first edge 11, the red light chip 21 and the white light chip 24 are arranged at positions close to the left first edge 11 in the same manner as the right edge is taken as the first edge 11, which is not described herein again.
Optionally, fig. 7 is a schematic structural diagram of another display module according to an embodiment of the present invention. On the basis of the above-described embodiments, as shown in fig. 7, in each pixel 20, the red wafer 21, the green wafer 22, the blue wafer 23, and the white wafer 24 are arranged in a 2 × 2 array, and the red wafer 21 and the white wafer 24 are sequentially arranged in a direction parallel to the extending direction of the first edge 11.
Specifically, taking the right edge of the display module substrate 10 shown in fig. 7 as the first edge 11 as an example, in the pixel 20 including four wafers, the wafers may be further arranged in a 2 × 2 array. In a 2 × 2 array, the red light chips 21 and the white light chips 24 are required to be arranged in a row close to the first edge 11, and the green light chips 22 and the blue light chips 23 are arranged in a row far from the first edge 11, so that the divergence angle of the emergent light of the red light chips 21 is reduced, the light-emitting efficiency of the red light chips 21 is improved, the white balance is adjusted through the white light chips 24, the side light overflow phenomenon at the splicing position of the first edge 11 of the display module is improved, and the display brightness of the display module is improved.
Alternatively, on the basis of the above embodiment, with continued reference to fig. 7, the extending directions of the red light wafer 21, the green light wafer 22, the blue light wafer 23 and the white light wafer 24 have the same preset angle θ with the extending direction of the first edge 11; wherein the preset angle theta is smaller than 90 deg.
Specifically, a certain preset angle theta is set between the extending direction of each wafer along the extending direction of the wafer and the extending direction of the first edge 11, and 0 degrees < theta <90 degrees, so that light superposition or shielding generated between the wafers along the direction perpendicular to the first edge 11 can be reduced to a certain extent, a user can observe the wafers in the direction perpendicular to the first edge 11 by the display module without black lines, and the display effect is improved. Preferably, as shown in fig. 7, the predetermined angle θ is 45 °, so as to obtain a better display effect.
For the arrangement sequence of the wafers in each pixel 20, in a row close to the first edge 11, the arrangement sequence of the red light wafer 21 and the white light wafer 24 can be interchanged, and the arrangement sequence of the green light wafer 22 and the blue light wafer 23 can be interchanged, so that the color cast phenomenon at the splicing position of the first edge 11 can be improved, and the light color consistency can be improved. Exemplarily, fig. 8 is a schematic diagram of a wafer arrangement in another pixel provided by an embodiment of the present invention, and fig. 9 is a schematic diagram of a wafer arrangement in another pixel provided by an embodiment of the present invention. As shown in fig. 7-9, the wafers in each pixel 20 may be arranged in a clockwise or counterclockwise order from near the first edge 11 to far from the first edge 11. For example, the red light wafer 21, the white light wafer 24, the green light wafer 22 and the blue light wafer 23 may be arranged in sequence, the white light wafer 24, the red light wafer 21, the blue light wafer 23 and the green light wafer 22 may be arranged in sequence, or the red light wafer 21, the white light wafer 24, the blue light wafer 23 and the green light wafer 22 may be arranged in sequence. The arrangement of the different photochromic wafers is not limited to the arrangement provided in the embodiment, and other wafer arrangements satisfying the conditions are also included in the embodiment.
It should be noted that, if the left edge of the substrate 10 is taken as the first edge 11, the red light chip 21 and the white light chip 24 are arranged at positions close to the left first edge 11 in the same manner as the right edge is taken as the first edge 11, which is not described herein again.
Optionally, fig. 10 is a schematic structural diagram of another display module according to an embodiment of the present invention. On the basis of the above-described embodiments, as shown in fig. 10, in each pixel 20, the red wafer 21 and the white wafer 24 are sequentially arranged in a direction perpendicular to the extending direction of the first edge 11, and the red wafer 21 is closer to the first edge 11 than the white wafer 24.
The green and blue wafers 22 and 23 are positioned at both sides of the red and white wafers 21 and 24 in the extending direction of the first edge 11.
Specifically, taking the right edge of the display module substrate 10 shown in fig. 10 as the first edge 11 as an example, in the pixel 20 including four chips, the chips may be further arranged in a 1-2-1 manner, that is, the red chip 21 and the white chip 24 are sequentially arranged in a direction perpendicular to the first edge 11, and the green chip 22 and the blue chip 23 are respectively arranged on both sides of the red chip 21 and the white chip 24 in the extending direction of the first edge 11. Therefore, the red wafer 21 is closer to the first edge 11 than the green wafer 22 and the blue wafer 23, so that the color shift phenomenon at the junction of the first edges 11 of the substrates 10 is improved, and the light color consistency within each pixel 20 can be improved. Illustratively, the green chip 22 and the blue chip 23 may be located on a midperpendicular of a line connecting the geometric centers of the red chip 21 and the white chip 24.
Alternatively, on the basis of the above embodiment, with continued reference to fig. 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.
Specifically, the red light chip 21 and the white light chip 24 are sequentially arranged along a direction perpendicular to the first edge 11, and the extending direction of the red light chip 21 and the extending direction of the white light chip 24 are perpendicular to the extending direction of the first edge 11, but the white light chip 24 is used for adjusting white balance, so that the overall brightness of the display module is improved, and the influence on the color is small. 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 no black line appears when a user observes from the display module in the direction perpendicular to the first edge 11, thereby improving the display effect.
In each pixel 20, fig. 11 is a schematic diagram of a wafer arrangement in another pixel provided by the embodiment of the present invention. As shown in fig. 10 and 11, the positions of the green chip 22 and the blue chip 23 may be interchanged, which is not limited herein.
Fig. 12 is a schematic structural diagram of another display module according to an embodiment of the present invention. If the left edge of the substrate 10 is used as the first edge 11, as shown in fig. 12, the red light chip 21 is disposed at a position close to the left first edge 11, and the white light chip 24 is disposed at a position adjacent to the red light chip 21 along a direction perpendicular to the first edge 11, so that the color shift phenomenon of the left first edge 11 can be improved, and the light color consistency of the display module can be improved.
The embodiment of the invention also provides a display panel. Fig. 13 is a schematic structural diagram of a display panel according to an embodiment of the present invention.
