Description

Technical Field

[0001] The invention relates to an electronic device, and in particular to a display device. Background Art

[0002] In recent years, with the popularization of display devices, users' requirements for the size of display devices and display screens have gradually increased. And spliced ​​displays are considered to be one of the solutions to meet the above requirements. For example, multiple smaller light-emitting units can be transferred to the target circuit board to form a large-sized spliced ​​display device to meet the user's demand for large-size displays. However, in a borderless spliced ​​display, the joints between the light-emitting units are prone to cause problems such as uneven color distribution, color cast or insufficient brightness, making it easy for the splicing of the spliced ​​display to form black lines or yellow lines on the display screen that are noticed by users, thereby affecting the viewing experience. Therefore, how to improve the above phenomenon has also become a topic for relevant manufacturers. Summary of the invention

[0003] The present invention provides a display device, which effectively improves the problem of color deviation caused by splicing of spliced ​​displays and has a good display effect.

[0004] In one embodiment of the present invention, a display device includes a plurality of light-emitting units arranged adjacent to each other, wherein the light-emitting units include a plurality of pixels. Each of the plurality of pixels includes a plurality of sub-pixels, and the plurality of sub-pixels are arranged in an L-shape, wherein two sides of the pixel are substantially parallel to two sides of the light-emitting unit. The plurality of light-emitting units include a first light-emitting unit and a second light-emitting unit adjacent to each other, wherein the first light-emitting unit has a plurality of first pixels, and the second light-emitting unit has a plurality of second pixels, wherein the plurality of first pixels and the plurality of second pixels are centrally symmetrical.

[0005] Based on the above, in the display device of the embodiment of the present invention, multiple pixels in the light-emitting unit are arranged in the shape of an English letter L, or it can also be understood as an array in which each sub-pixel is arranged in a right-angled triangle. Therefore, when the light-emitting unit needs to be cut during the packaging process, the L-shaped pixels at the edge of the light-emitting unit have a lower risk of breakage than the pixels arranged in a conventional rectangular shape. Not only that, on two adjacent light-emitting units, the pixels of each of the two light-emitting units are arranged in a centrally symmetrical manner. That is, the arrangement pattern of the pixels of one light-emitting unit and the arrangement pattern of the pixels of another adjacent light-emitting unit are substantially 180 degrees apart from each other. Therefore, the light beams of different colors emitted by the pixels on both sides of the splicing can be fully mixed. When the display device is lit, the problem of different colors of splicing lines or dark lines at the splicing can be effectively reduced, further improving the image quality of the display screen and improving the user's viewing experience.

[0006] In order to make the above features and advantages of the present invention more clearly understood, embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it may be directly on or connected to another element, or an intermediate element may also exist. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there is no intermediate element. As used herein, "connection" may refer to physical and / or electrical connection. Furthermore, "electrical connection" may be the presence of other elements between two elements.

[0028] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and description to refer to the same or like parts.

[0029] Figure 1 is a top view schematic diagram of a display device according to an embodiment of the present invention. Figure 1 The display device 10 may include a plurality of light emitting units 100 and a driving substrate 200, wherein the plurality of light emitting units 100 are disposed on the driving substrate 200 and overlap and are electrically connected to the driving substrate 200 in the direction Z. However, the present invention does not limit the electrical connection method of the plurality of light emitting units 100. In addition, Figure 1 Four light-emitting units are schematically drawn, namely, a first light-emitting unit 100A, a second light-emitting unit 100B, a third light-emitting unit 100C, and a fourth light-emitting unit 100D. A plurality of light-emitting units may be arranged in an array in direction X and direction Y, for example, in a 2*3 matrix array, a 3*3 matrix array, a 4*4 matrix array, or other number of arrays, and the present invention is not limited thereto. Direction X, direction Y, and direction Z may be substantially perpendicular to each other in this document, but the present invention is not limited thereto.

[0030] Further, the first light-emitting unit 100A, the second light-emitting unit 100B, the third light-emitting unit 100C, and the fourth light-emitting unit 100D may respectively include a plurality of pixels to provide a display light beam in the direction Z. For example, the first light-emitting unit 100A has a plurality of first pixels 110A, and the second light-emitting unit 100B has a plurality of second pixels 110B. The pixel may further include a plurality of sub-pixels. For example, the first pixel 110A may include a sub-pixel 111A that emits red light, a sub-pixel 112A that emits green light, and a sub-pixel 113A that emits blue light. Similarly, the second pixel 110B may include a sub-pixel 111B that emits red light, a sub-pixel 112B that emits green light, and a sub-pixel 113B that emits blue light. That is, sub-pixels 111A and 111B may be red sub-pixels, sub-pixels 112A and 112B may be green sub-pixels, and sub-pixels 113A and 113B may be blue sub-pixels. The third light-emitting unit 100C and the fourth light-emitting unit 100D may also have the above configuration, which is not repeated here. In addition, the above-mentioned sub-pixels of each color may be a single micro light-emitting diode (Micro LED), a single sub-millimeter light-emitting diode (Mini LED), or a single organic light-emitting diode (OLED). The present invention is not limited to this. The structure of each color sub-pixel may also be a front-mounted LED, a vertical LED, or a flip-chip LED, and the present invention is not limited to this. Among the first pixel 110A and the second pixel 110B, the number ratio of various light-emitting diodes can be adjusted accordingly as required. The present invention is not limited to this. The above-mentioned multiple sub-pixels can be electrically connected to each light-emitting unit 100 to provide a display screen in direction Z. In other embodiments, the multiple light-emitting units 100 may also be non-self-luminous light-emitting units. For example, each of the multiple light-emitting units 100 may include components such as a liquid crystal layer, a backlight module, and a color filter, so that the display device 10 may be a spliced ​​liquid crystal display, and the present invention is not limited to this.

[0031] On the other hand, each light-emitting unit 100 may include alternately stacked wire redistribution layers, including multiple metal layers (not shown) and multiple insulating layers (not shown). One of these metal layers is used to form multiple conductive patterns, another of them is used to form multiple pad patterns, and another of them is used to form multiple transfer patterns. These transfer patterns can be electrically connected to these conductive patterns and these pad patterns through multiple contact holes of these insulating layers. That is, these metal layers can form multiple conductive paths that are electrically insulated from each other in the light-emitting unit 100. The sub-pixels of multiple colors connected to these conductive patterns on the light-emitting unit 100 can be electrically connected to these pad patterns through these conductive paths. The light-emitting unit 100 can be electrically connected to the driving substrate 200 through these pad patterns. That is, the driving substrate 200 includes at least one driving circuit chip IC, which, for example, has transistors (transistors) or integrated circuits (integrated circuits (ICs)) that can be electrically connected to multiple sub-pixels to control the display signals of multiple sub-pixels, which is not limited here.

[0032] It is worth mentioning that the sub-pixels of each light-emitting unit 100 of the present embodiment can be arranged in the shape of the English letter "L", or in the arrangement of a right triangle. For example, in the first pixel 110A of the first light-emitting unit 100A, the sub-pixel 111A and the sub-pixel 112A can be arranged in the direction X, and the sub-pixel 112A and the sub-pixel 113A can be arranged in the direction Y. Similarly, in the second pixel 110B of the second light-emitting unit 100B, the sub-pixel 111B and the sub-pixel 112B can be arranged in the direction X, and the sub-pixel 112B and the sub-pixel 113B can be arranged in the direction Y. The first pixel 110A and the second pixel 110B both form L-type pixels, and taking the first pixel 110A as an example, one side of the L-type pixel is substantially parallel to the side 101 of the first light-emitting unit 100A, and the other side of the L-type pixel is substantially parallel to the side 102 of the first light-emitting unit 100A.

[0033] It is worth mentioning that, in addition to the L-shaped arrangement of the pixels of each light-emitting unit 100, the pixels on each adjacent light-emitting unit 100 can be arranged symmetrically with respect to each other. It should be noted that, in this article, there is no other light-emitting unit between the first light-emitting unit 100A and the second light-emitting unit 100B, that is, the first light-emitting unit 100A and the second light-emitting unit 100B are adjacent to each other, so the first light-emitting unit 100A and the third light-emitting unit 100C can also be called adjacent to each other.

[0034] Figure 2 for Figure 1Schematic diagram of an enlarged area A in a display device of FIG. Area A enlarges a portion of the area adjacent to the first light-emitting unit 100A and the second light-emitting unit 100B, and the portion of the driving substrate 200 exposed between the first light-emitting unit 100A and the second light-emitting unit 100B can be regarded as the splicing area SP of the display device 10. See FIG. Figure 1 and Figure 2 For the convenience of explanation, the first light-emitting unit 100A schematically depicts two first pixels 110A, namely, the first pixel 110A1 and the first pixel 110A2, and the second light-emitting unit 100B schematically depicts two second pixels 110B, namely, the second pixel 110B1 and the second pixel 110B2. In this embodiment, the arrangement of each pixel on each light-emitting unit 100 can be completely the same during the manufacturing process, but during the splicing process, the arrangement directions of the adjacent first light-emitting unit 100A and the third light-emitting unit 100C can all be arranged in the direction X, and the second light-emitting unit 100B and the fourth light-emitting unit 100D can all be arranged in the negative direction X, so that after the first light-emitting unit 100A and the second light-emitting unit 100B are spliced, the arrangement pattern of the first pixel 110A and the arrangement pattern of the second pixel 110B can be a centrally symmetrical arrangement relationship.

[0035] Reference Figure 2 For example, with the shape centers of the first pixel 110A1 and the first pixel 110A2 as the rotation point and the direction Z as the rotation axis, after rotating 180 degrees, the patterns and sub-pixels of the second pixel 110B1 and the second pixel 110B2 can be substantially completely consistent. In other words, the first pixel 110A1 and the second pixel 110B2 can form a centrally symmetrical pattern, and the first pixel 110A2 and the second pixel 110B1 can form a centrally symmetrical pattern.

[0036] Through the above configuration, the light beams of different colors emitted between the adjacent first pixel 110A1 and the second pixel 110B1 on the opposite sides of the splicing area SP in the direction Y can complement each other. For example, the sub-pixel 111A and the sub-pixel 112A of the first pixel 110A1 respectively emit a red light beam and a green light beam, which can be fully mixed with the blue light beam emitted by the sub-pixel 113B in the second pixel 110B1 adjacent to the other side of the splicing area SP, so that the display screen near the splicing area SP allows the viewer to observe the white display light beam, so that the color shift phenomenon of the splicing area SP can be reduced or eliminated. On the other hand, compared with the conventional rectangular arrangement of pixels, the L-shaped first pixels 110A1, 110A2 and the second pixels 110B1, 110B2 are respectively located at the edges of the first light-emitting unit 100A and the second light-emitting unit 100B, which can have a lower risk of breakage when cutting is required during the light-emitting unit manufacturing process, and also improve the yield rate during the product manufacturing process. It is particularly noted that “the first pixel 110A1 and the second pixel 110B1 are adjacent” here means that there are no other pixels at the pitch between the first pixel 110A1 and the second pixel 110B1. Similarly, “two sub-pixels are adjacent” means that there are no other sub-pixels at the pitch between the two sub-pixels.

[0037] It should be noted that the present invention is only described by taking the two sides of the splicing area SP in the region A in the direction Y as an example. Figure 1 The splicing area of ​​the first light-emitting unit 100A and the third light-emitting unit 100C in the embodiment can also have the above-mentioned effects. The relevant contents can be referred to the above paragraphs and will not be repeated here.

[0038] Please continue to refer to Figure 2 . On the other hand, in order to make the luminous intensity of the stitching area SP consistent with the luminous intensity at the center of the light-emitting unit 100, the pitch between the pixels of different light-emitting units 100 may be substantially the same as the pitch of the pixels on the same light-emitting unit 100. For example, the first pitch P1 between the first pixel 110A1 and the second pixel 110B1 may be defined as the distance from the center of the sub-pixel 112A of the first pixel 110A1 to the center of the sub-pixel 111B of the second pixel 110B1. The first pitch P1 may be substantially the same as the pitch between the first pixel 110A1 and the first pixel 110A2, or the same as the pitch between the second pixel 110B1 and the second pixel 110B2. For example, the pitch size between the sub-pixel 113B of the second pixel 110B1 and the sub-pixel 112B of the second pixel 110B2 may be substantially equal to the size of the first pitch P1. In addition, since each pixel in the embodiment of the present invention is an L-type pixel, in Figure 2In the example, no other sub-pixels may be present at the first pitch P1. Similarly, no other sub-pixels may be present at the pitch between the sub-pixel 111A of the first pixel 110A2 and the sub-pixel 112B of the second pixel 110B2.

[0039] On the other hand, the pitch between each sub-pixel in a single pixel can be smaller. For example, the pitch between each sub-pixel of the second pixel 110B1 can be defined as a second pitch P2, and the second pitch P2 can be defined as the pitch between sub-pixel 112B and sub-pixel 113B, and the second pitch P2 can also be the same as the pitch between sub-pixel 111B and sub-pixel 112B. Further, the ratio of the first pitch P1 to the second pitch P2 can be greater than or equal to 3. In some embodiments, the first pitch P1 can be approximately 744 microns, and the second pitch P2 can be approximately 248 microns. However, the present invention is not limited to this. Under the above configuration, since the first pitch P1 between each pixel on two adjacent light-emitting units 100 and the pitch between each pixel on the same light-emitting unit 100 can be substantially the same, when the display device 10 is in a lit state, the display brightness of the splicing area SP can be approximately the same as the display brightness of other areas in the light-emitting unit 100. Therefore, the problem of low display brightness and easy formation of dark lines at the joints in the spliced ​​display can be alleviated or avoided, and the display image quality of the display device 10 is effectively improved.

[0040] It is worth mentioning that the shapes of adjacent pixels on the same light-emitting unit 100 can be arranged in an alternating manner. For example, the first pixel 110A1 and the first pixel 110A2 on the first light-emitting unit 100A are adjacent to each other and arranged alternately. If the first pixel 110A1 forms a linear symmetrical pattern with a straight line extending in the direction X as the axis of symmetry, the shape of the linear symmetrical pattern can substantially overlap with the first pixel 110A2. Similarly, the second pixel 110B1 and the second pixel 110B2 on the second light-emitting unit 100B are adjacent to each other and arranged alternately. If the second pixel 110B1 forms a linear symmetrical pattern with a straight line extending in the direction X as the axis of symmetry, the shape of the linear symmetrical pattern can substantially overlap with the second pixel 110B2. However, the present invention is not limited to this.

[0041] Other modified embodiments will be listed below to illustrate the present invention in detail, wherein the same components will be marked with the same symbols, and the description of the same technical content will be omitted. For the omitted parts, please refer to the aforementioned embodiments and will not be repeated below.

[0042] Figures 3 to 25 It is a top view schematic diagram of various variant embodiments of the present invention. Figures 3 to 13 , and Figure 2 The pixel arrangement of the display device 10 is similar, and the difference is that the sub-pixels in each pixel are arranged in different directions. Figures 2 to 13 In the figure, the two sub-pixels of the first pixel 110A and the second pixel 110B are the two sub-pixels with the smallest distance in the direction Y, and the colors of the display light beams emitted by them are different.

[0043] by Figure 2 For example, in the direction Y, the sub-pixel 111A of the first pixel 110A1 and the sub-pixel 113B of the second pixel 110B1 are the two with the shortest distance in the direction Y (the shortest distance between the sub-pixel 111A and the sub-pixel 113B may be the difference between the first pitch P1 and the second pitch P2, for example, twice the second pitch P2. Subsequent variant embodiments may be analogized and will not be described in detail hereinafter). Moreover, one of the sub-pixel 111A and the sub-pixel 113B is a red sub-pixel that emits red light, and the other is a blue sub-pixel that emits blue light. Figure 5 , Figure 6 and Fig. 9 The above configuration is similar, and the arrangement order of the remaining sub-pixels can be replaced arbitrarily. Figure 2 and Figure 6 In the modified embodiment, the difference is that the positions of the red sub-pixel 111A and the blue sub-pixel 113A in the first pixels 110A1 and 110A2 are swapped, and the positions of the red sub-pixel 111B and the blue sub-pixel 113B in the second pixels 110B1 and 110B2 are swapped. The differences of other embodiments can refer to the corresponding configurations in the above paragraphs and figures, and will not be repeated here.

[0044] Similarly, Figure 3 For example, the sub-pixel 112A of the first pixel 110A1 and the sub-pixel 113B of the second pixel 110B1 are the two with the shortest distance in direction Y. One of the sub-pixel 112A and the sub-pixel 113B is a green sub-pixel emitting green light, and the other is a blue sub-pixel emitting blue light. Figure 4 , Fig.11 and Fig.12 The above configuration is similar, and the arrangement order of the remaining sub-pixels can be replaced arbitrarily. Figure 3 and Fig.11 In the modified embodiment, the difference is that the positions of the green sub-pixel 112A and the blue sub-pixel 113A in the first pixels 110A1 and 110A2 are swapped, and the positions of the green sub-pixel 112B and the blue sub-pixel 113B in the second pixels 110B1 and 110B2 are swapped. The differences of other embodiments can refer to the corresponding configurations in the above paragraphs and figures, and will not be repeated here.

[0045] Similarly, Figure 7For example, the sub-pixel 112A of the first pixel 110A1 and the sub-pixel 111B of the second pixel 110B1 are the two with the shortest distance in direction Y. One of the sub-pixel 112A and the sub-pixel 111B is a green sub-pixel emitting green light, and the other is a red sub-pixel emitting red light. Figure 8 , Fig.10 and Fig.13 The above configuration is similar, and the arrangement order of the remaining sub-pixels can be replaced arbitrarily. Figure 7 and Fig.13 In the variant embodiment, the difference is that the positions of the green sub-pixel 112A and the red sub-pixel 111A in the first pixels 110A1 and 110A2 are swapped, and the positions of the green sub-pixel 112B and the red sub-pixel 111B in the second pixels 110B1 and 110B2 are swapped. The differences of other embodiments can refer to the corresponding configurations in the above paragraphs and figures, and will not be repeated here.

[0046] On the other hand, the arrangement shapes of the pixels on the same light emitting unit 100 of the present invention may also be substantially the same. Fig.14 In a modified embodiment, the first pixel 110A1 and the first pixel 110A2 on the first light-emitting unit 100A can both be arranged in the outline of the English letter "L" rotated 180 degrees in the direction X; and the second pixel 110B1 and the second pixel 110B2 on the second light-emitting unit 100B can both be arranged in the outline of the English letter "L" in the direction X. Figures 15 to 25 The modified embodiments may also have a similar configuration as described above.

[0047] Furthermore, in Figures 14 to 25 In the embodiment of FIG. 1 , a light emitting unit 100 and another adjacent light emitting unit 100 , the two sub-pixels of which are closest to each other, can emit display light beams of the same color. Fig.14 For example, the sub-pixel 113A of the first pixel 110A1 and the sub-pixel 113B of the second pixel 110B1 are the two with the shortest distance in the direction Y, and the display light beams emitted by them can both be blue light. Figures 15 to 17 The embodiments of the present invention can also be configured in the same manner as above, and the arrangement order of the sub-pixels of other colors can be replaced with each other. Fig.14 and Fig.16 In the modified embodiment, the difference is that the positions of the red sub-pixel 111A and the green sub-pixel 112A in the first pixels 110A1 and 110A2 are swapped, and the positions of the green sub-pixel 112B and the red sub-pixel 111B in the second pixels 110B1 and 110B2 are swapped. The differences of other embodiments can refer to the corresponding configurations in the above paragraphs and figures, and will not be repeated here.

[0048] Similarly, Fig.18 For example, the sub-pixel 111A of the first pixel 110A1 and the sub-pixel 111B of the second pixel 110B1 are the two with the shortest distance in the direction Y, and the display light beams emitted by them can both be red light. Figures 19 to 21 The embodiments of the present invention can also be configured in the same manner as above, and the arrangement order of the sub-pixels of other colors can be replaced with each other. Fig.18 and Fig. 20 In the variant embodiment, the difference is that the positions of the green sub-pixel 112A and the blue sub-pixel 113A in the first pixels 110A1 and 110A2 are swapped, and the positions of the blue sub-pixel 113B and the green sub-pixel 112B in the second pixels 110B1 and 110B2 are swapped. The differences of other embodiments can refer to the corresponding configurations in the above paragraphs and figures, and will not be repeated here.

[0049] Similarly, Fig. 22 For example, the sub-pixel 112A of the first pixel 110A1 and the sub-pixel 112B of the second pixel 110B1 are the two with the shortest distance in the direction Y, and the display light beams emitted by them can both be green light. Figure 22 to Figure 25 The embodiments of the present invention can also be configured in the same manner as above, and the arrangement order of the sub-pixels of other colors can be replaced with each other. Fig. 22 and Fig.24 In the modified embodiment, the difference is that the positions of the red sub-pixel 111A and the blue sub-pixel 113A in the first pixels 110A1 and 110A2 are swapped, and the positions of the blue sub-pixel 113B and the red sub-pixel 111B in the second pixels 110B1 and 110B2 are swapped. The differences of other embodiments can refer to the corresponding configurations in the above paragraphs and figures, and will not be repeated here.

[0050] In summary, in the display device of the embodiment of the present invention, multiple pixels in the light-emitting unit are arranged in the shape of an English letter L, or it can also be understood as an array in which each sub-pixel is arranged in a right-angled triangle. Therefore, when the light-emitting unit needs to be cut during the packaging process, the L-shaped pixels at the edge of the light-emitting unit have a lower risk of breakage than the pixels arranged in a conventional rectangular shape. Not only that, on two adjacent light-emitting units, the pixels of each of the two light-emitting units are arranged in a centrally symmetrical manner. That is, the arrangement pattern of multiple pixels of a light-emitting unit and the arrangement pattern of multiple pixels of another adjacent light-emitting unit are substantially 180 degrees apart from each other. Therefore, the light beams of different colors emitted by the pixels on both sides of the splicing can be fully mixed. When the display device is lit, the problem of different colors of splicing lines or dark lines at the splicing can be effectively reduced, further improving the image quality of the display screen and improving the user's viewing experience.

[0051] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. Any person having ordinary knowledge in the technical field may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
