Description

Technical Field

[0001] This disclosure relates to a display device, and more particularly to a display device that can eliminate color leakage at the seams between display panels. Background Technology

[0002] In the current display technology field, Micro LED display devices have become an important development trend due to their advantages of high pixel density (PPI) and modular splicing. To effectively improve pixel area utilization, these display panels typically use a Delta arrangement (or staggered arrangement) where the center points of red, green, and blue light-emitting elements are arranged in a triangle for their sub-pixels. Although panel splicing usually uses a left-right symmetrical arrangement to ensure the continuity of the sub-pixel arrangement, due to limitations in product structure (such as the location of the drive flexible flat cable), there are still situations in practical applications where a non-standard top-side symmetrical arrangement is required.

[0003] However, when using a single-design panel for top-side splicing, the existing subpixel arrangement will cause problems at the splicing seam. Specifically, on both sides of the seam, light-emitting elements of the same color will appear adjacent to each other. This adjacent arrangement of monochromatic light-emitting elements will cause a noticeable monochromatic color shift in the splicing area, affecting the overall visual uniformity, white balance, and color fidelity of the image. An easy way to eliminate this problem is to design and manufacture two panels with mirror-image pixel arrangements for splicing, but this method not only increases the complexity of the product design but also increases the cost of the photomask and the overall manufacturing process.

[0004] Therefore, how to propose a display device that can effectively solve the above problems is one of the issues that the industry is currently eager to invest research and development resources to address. Summary of the Invention

[0005] In view of this, one of the purposes of this disclosure is to provide a display device that can effectively solve the above-mentioned problems.

[0006] To achieve the above objectives, according to one embodiment of this disclosure, a display device includes a first display panel, a second display panel, and a signal source. The first and second display panels each have a first side and include a plurality of pixels arranged in an alternating pattern. The pixels are arranged sequentially in multiple pixel rows away from the first side. Each pixel includes a first color light-emitting element. A pixel row includes a first pixel row adjacent to the first side. The first and second display panels are spliced ​​together such that the first color light-emitting elements in the first pixel rows of the first and second display panels are adjacent to each other at the splicing seam between the first and second display panels. The signal source is configured such that the first color light-emitting elements in the first pixel rows of the second display panel are in a substantially non-light-emitting state.

[0007] In one or more embodiments disclosed herein, each pixel further includes a second color light-emitting element and a third color light-emitting element. The first color light-emitting element, the second color light-emitting element, and the third color light-emitting element in each pixel are arranged in a triangle.

[0008] In one or more embodiments disclosed herein, the signal source is further configured to increase the brightness of pixels in the first pixel row of the first display panel and the second display panel.

[0009] In one or more embodiments disclosed herein, the pixel row further includes a second pixel row adjacent to the first pixel row. The signal source is further configured to: cause the pixels in the first pixel row to operate in an intermittent light-emitting mode; cause the second pixel row of the first display panel to be substantially non-light-emitting; cause the first color light-emitting element in the second pixel row of the second display panel to operate in the intermittent light-emitting mode; and cause the other color light-emitting elements in the second pixel row of the second display panel to be substantially non-light-emitting.

[0010] In one or more embodiments disclosed herein, the pixel row further includes a third pixel row adjacent to the second pixel row. The signal source is further configured such that the first color light-emitting element in the third pixel row of the second display panel is in a substantially non-light-emitting state.

[0011] In one or more embodiments disclosed herein, the pixel arrangement pattern of the first display panel is the same as that of the second display panel.

[0012] In one or more embodiments disclosed herein, the pixel arrangement patterns of the first display panel and the second display panel are horizontally mirror images of each other.

[0013] In one or more embodiments disclosed herein, each pixel further includes a second color light-emitting element and a third color light-emitting element. The second color light-emitting elements of the first display panel and the second color light-emitting elements of the second display panel are collinearly arranged in a direction perpendicular to the first side to form a plurality of first straight lines crossing the seam. The third color light-emitting elements of the first display panel and the third color light-emitting elements of the second display panel are collinearly arranged in this direction to form a plurality of second straight lines crossing the seam.

[0014] In one or more embodiments disclosed herein, each pixel further includes a second color light-emitting element and a third color light-emitting element. The back panel of the first display panel and the back panel of the second display panel have the same circuit layout. The second color light-emitting element and the third color light-emitting element are arranged in interchangeable positions on the back panel.

[0015] In one or more embodiments disclosed herein, the joint width of the splice seam is less than about 1 mm.

[0016] To achieve the above objectives, according to one embodiment of the present disclosure, a display device includes a first display panel, a second display panel, and a control circuit. The first and second display panels each have a first side and include a plurality of pixels arranged in an alternating pattern. The pixels are arranged sequentially in multiple pixel rows away from the first side. Each pixel includes a first color light-emitting element. A pixel row includes a first pixel row adjacent to the first side. The first and second display panels are spliced ​​together such that the first color light-emitting elements in the first pixel rows of the first and second display panels are adjacent to each other at the splicing seam between the first and second display panels. The control circuit is configured to keep the first color light-emitting elements in the first pixel rows of the second display panel substantially non-light-emitting.

[0017] In summary, in the display device disclosed herein, to solve the technical problem of adjacent monochrome light-emitting elements and significant color shift caused by the splicing seam of a display panel containing staggered pixels due to the first side splicing, this disclosure uses a signal source or control circuit to make the first color light-emitting element in the first pixel row adjacent to the splicing seam of one of the display panels substantially non-emitting. This transforms the originally identical light-emitting elements on both sides of the splicing seam into opposite light-emitting elements of different colors, achieving the technical effect of eliminating or reducing monochrome color leakage at the splicing seam, while avoiding the increased manufacturing costs caused by designing two completely different panels. Furthermore, by increasing the brightness of the pixels in the first pixel row adjacent to the splicing seam and combining the pixels to operate in an intermittent light-emitting mode, while turning off or adjusting the state of the light-emitting elements in the adjacent second pixel row, the technical effect of visually reducing or eliminating the seam width can be achieved by utilizing brightness overflow. This method addresses the monochrome adjacent problem that may occur in the outermost pixel rows after splicing seam compensation. In this case, the first color light-emitting elements in specific pixel rows can be further turned off to ensure color uniformity outside the splicing seam. Furthermore, this disclosure also provides a cost-saving solution: even if the pixel arrangement patterns of the panels are horizontally mirrored, two panels with similar structures can be produced by using a backplate with the same circuit layout and by interchanged positions of the second and third color light-emitting elements, thereby effectively saving photomask and manufacturing costs.

[0052] The following drawings disclose several embodiments of this disclosure. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this disclosure. That is, in some embodiments of this disclosure, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0053] Please refer to Figure 1 . Figure 1 A schematic diagram illustrating a display device 100 according to an embodiment of this disclosure is provided. Figure 1 As shown, in this embodiment, the display device 100 includes a first display panel 110, a second display panel 120, and a signal source 130 electrically connected to the first display panel 110 and the second display panel 120 (see Figure 130). Figure 2The first display panel 110 includes a back panel 111 and a plurality of pixels PX arranged in an alternating pattern. The back panel 111 has opposing first sides 111a and second sides 111b, and includes a flexible circuit board 111c disposed on the second side 111b. The pixels PX on the back panel 111 are arranged in a plurality of pixel rows away from the first side 111a. Each pixel row includes a first pixel row PR11 adjacent to the first side 111a. The second display panel 120 includes a back panel 121 and a plurality of pixels PX arranged in an alternating pattern. The back panel 121 has opposing first sides 121a and second sides 121b, and includes a flexible circuit board 121c disposed on the second side 121b. The pixels PX on the back panel 121 are arranged in a plurality of pixel rows away from the first side 121a. Each pixel row also includes a first pixel row PR21 adjacent to the first side 121a.

[0054] In some embodiments, the electronic components on the flexible circuit boards 111c and 121c are manufactured using flip chip bonding technology, but this disclosure is not limited thereto.

[0055] like Figure 1 As shown, in this embodiment, each pixel PX includes a first color light-emitting element E1, a second color light-emitting element E2, and a third color light-emitting element E3. The first color light-emitting element E1, the second color light-emitting element E2, and the third color light-emitting element E3 in each pixel PX are arranged in a triangle. This is one way in which the pixel PX is arranged in an alternating pattern, but this disclosure is not limited to this.

[0056] In some embodiments, the first color light-emitting element E1, the second color light-emitting element E2, and the third color light-emitting element E3 emit red light, green light, and blue light, respectively, but this disclosure is not limited thereto.

[0057] Please refer to Figure 2 as well as Figure 3 . Figure 2 For illustration Figure 1 Functional block diagram of the display device 100. Figure 3 This is a partially enlarged schematic diagram of the display device 100 at the splice seam G in a first embodiment. Figure 2 and Figure 3As shown, in this embodiment, the first display panel 110 and the second display panel 120 are spliced ​​together with their first side edges 111a and 121a adjacent to each other (also referred to as top-side splicing), causing the first color light-emitting element E1 in the first pixel row PR11 of the first display panel 110 and the first color light-emitting element E1 in the first pixel row PR21 of the second display panel 120 to be adjacent to the splicing seam G between the first display panel 110 and the second display panel 120. The first display panel 110 and the second display panel 120 further include independent first control circuit 112 and second control circuit 122, respectively. The signal source 130 controls the display of the first display panel 110 via the first control circuit 112 and controls the display of the second display panel 120 via the second control circuit 122. The signal source 130 is configured such that the first color light-emitting element E1 in the first pixel row PR21 of the second display panel 120 is in a substantially non-light-emitting state. In other words, the signal source 130 is configured to enable the other color light-emitting elements (i.e., the second color light-emitting element E2 and the third color light-emitting element E3) in the first pixel row PR21 of the second display panel 120 to be in a light-emitting state. This allows the originally identical first color light-emitting elements E1 on both sides of the splicing seam G to be aligned, transforming the first color light-emitting elements E1 in the first pixel row PR11 of the first display panel 110 to be aligned with the second color light-emitting elements E2 and the third color light-emitting elements E3 in the first pixel row PR21 of the second display panel 120, thereby achieving the technical effect of eliminating or reducing monochrome color leakage in the splicing seam G. In other embodiments, the aforementioned control function of the signal source 130 on the second display panel 120 can be performed by the second control circuit 122, that is, the second control circuit 122 is configured to enable the first color light-emitting elements E1 in the first pixel row PR21 of the second display panel 120 to be in a substantially non-light-emitting state.

[0058] It should be noted that the aforementioned non-luminous state can be a completely off state or an extremely low luminous state. The extremely low luminous state refers to the brightness of the light-emitting element being controlled to a level below the critical value below which the human eye cannot visually perceive monochrome color leakage at the splicing seam G.

[0059] like Figure 3 As shown, in this embodiment, the seam width W of the splicing seam G is less than approximately 1 mm. This limiting condition is used to highlight that the color shift problem caused by adjacent monochrome elements only becomes apparent when the seam width W is relatively small. For example, the technical field to be addressed in this disclosure is high pixel density (PPI) Micro LED display devices.

[0060] Please refer to Figure 4 This is a partially enlarged schematic diagram illustrating a second embodiment of the display device 100 at the splicing seam G. For example... Figure 2 and Figure 4As shown, in this embodiment, in addition to performing... Figure 3 In addition to the operation of the illustrated embodiment, it is further configured to increase the brightness of pixels PX in the first pixel row PR11 of the first display panel 110 and the brightness of pixels PX in the first pixel row PR21 of the second display panel 120. This allows the brightness to overflow to the seam G, visually reducing or eliminating the seam width W. The brightness increase factor can be, for example, nine times, but this disclosure is not limited to this. The selection of the factor can be equivalent to the visual brightness required to fill the seam G. In other embodiments, the aforementioned control functions of the signal source 130 on the first display panel 110 can be performed by the first control circuit 112, and the aforementioned control functions of the signal source 130 on the second display panel 120 can be performed by the second control circuit 122.

[0061] Furthermore, in this embodiment, the pixel row also includes a second pixel row PR12 adjacent to the first pixel row PR11 and a second pixel row PR22 adjacent to the first pixel row PR21. The source 130 is further configured to: operate the pixels PX in the first pixel rows PR11 and PR21 in an intermittent light-emitting mode; keep the second pixel row PR12 of the first display panel 110 substantially non-light-emitting; operate the first color light-emitting element E1 in the second pixel row PR22 of the second display panel 120 in an intermittent light-emitting mode; and keep the other color light-emitting elements (i.e., the second color light-emitting element E2 and the third color light-emitting element E3) in the second pixel row PR22 of the second display panel 120 substantially non-light-emitting. Thus, while increasing the brightness of the first pixel rows PR11 and PR21 to visually reduce or eliminate the seam width W, the aforementioned intermittent light-emitting mode can further prevent bright lines from forming at the seam G. Furthermore, the operation of the signal source 130 to make the second color light-emitting element E2 and the third color light-emitting element E3 in the first pixel row PR21 and the first color light-emitting element E1 in the second pixel row PR22 of the second display panel 120 operate with the same interval light emission mode can also maintain the white balance of the second display panel 120 at the first pixel row PR21 and the second pixel row PR22. In other embodiments, the aforementioned control function of the signal source 130 on the first display panel 110 can be performed by the first control circuit 112, and the aforementioned control function of the signal source 130 on the second display panel 120 can be performed by the second control circuit 122.

[0062] At Figure 4 In this context, the aforementioned intermittent light emission mode refers to a situation in which two adjacent pixels PX (or light-emitting elements) in a pixel row are in a light-emitting state, while two adjacent pixels PX in a substantially non-light-emitting state are spaced apart. However, this disclosure is not limited to this.

[0063] Please refer to Figure 5This is a partially enlarged schematic diagram of the third embodiment of the display device 100 at the splicing seam G. In this embodiment, the pixel row further includes a third pixel row PR23 adjacent to the second pixel row PR22. In addition to performing... Figure 4 In addition to the operation of the illustrated embodiment, the first color light-emitting element E1 in the third pixel row PR23 of the second display panel 120 is further configured to be in a substantially non-light-emitting state. This ensures color uniformity outside the seam G, particularly addressing issues on the outermost edges (e.g.,...). Figure 4 This addresses the monochrome adjacency issue between the second pixel row PR22 and the third pixel row PR23. In other embodiments, the aforementioned control functions of the signal source 130 on the second display panel 120 can be performed by the second control circuit 122.

[0064] like Figure 1 As shown, in this embodiment, the pixel PX of the first display panel 110 and the pixel PX of the second display panel 120 have the same arrangement pattern. Therefore, the color leakage problem at the top edge can be solved by operating the signal source 130 or the second control circuit 122 without increasing additional panel design or manufacturing costs (e.g., photomask costs).

[0065] Please refer to Figure 6 This is a schematic diagram illustrating a display device 200 according to another embodiment of this disclosure. Figure 6 As shown, in this embodiment, the display device 200 includes a first display panel 110, a second display panel 220, and a signal source 130 (see reference). Figure 2 ), wherein the first display panel 110 is the same as the signal source 130. Figure 1 and Figure 2 The embodiment shown is therefore described in detail above, and will not be repeated here. The second display panel 220 also includes a back panel 121. This embodiment is different from... Figure 1 and Figure 2 The difference between the embodiments shown is that the pixel PX arrangement pattern of the second display panel 220 in this embodiment is a horizontal mirror image of the pixel PX arrangement pattern of the first display panel 110.

[0066] Specifically, such as Figure 6 As shown, the second color light-emitting element E2 of the first display panel 110 and the second color light-emitting element E2 of the second display panel 220 are perpendicular to the first side edges 111a and 121a (see reference). Figure 1The third color light-emitting elements E3 of the first display panel 110 and the third color light-emitting elements E3 of the second display panel 220 are collinearly arranged in direction D to form multiple first straight lines L1 crossing the splicing seam G. Therefore, it can be seen that... Figure 6 The second color light-emitting element E2 and the third color light-emitting element E3 in the pixel PX of the second display panel 220 are compared with Figure 1 In the second display panel 120, the second color light-emitting element E2 and the third color light-emitting element E3 in the pixels PX are reversed. This collinear arrangement helps maintain the visual uniformity of the splicing seam G and ensures the continuity of the arrangement of the three color light-emitting elements. Furthermore, the second color light-emitting element E2 and the third color light-emitting element E3 are interchanged on the first display panel 110 and the second display panel 220, and the backplate 111 of the first display panel 110 and the backplate 121 of the second display panel 220 have the same circuit layout. This design, with the same circuit layout but interchanged light-emitting element positions, aims to create two display panels with a shared circuit structure design for the backplates 111 and 121, saving on photomask and manufacturing costs and avoiding the high costs required to manufacture two completely different display panels.

[0067] Please refer to Figure 7 , Figure 8 as well as Figure 9 . Figures 7 to 9 The diagrams are enlarged views of the fourth, fifth, and sixth embodiments of the display device 200 at the splice seam G.

[0068] At Figure 7 In the fourth embodiment shown, the signal source 130 adopts the following... Figure 3 The control method of the illustrated embodiment involves configuring the signal source 130 to keep the first color light-emitting element E1 in the first pixel row PR21 of the second display panel 220 substantially non-emitting. This solution is suitable for panel splicing where the pixel arrangement patterns are horizontally mirrored. By turning off the first color light-emitting element E1 on one side, the color balance of the splicing seam G is further ensured, and color leakage is eliminated. In other embodiments, the second display panel 220 may include, for example, Figure 2 The second control circuit 122 shown can also perform the aforementioned control function of the signal source 130 on the second display panel 220, that is, the second control circuit 122 is configured to make the first color light-emitting element E1 in the first pixel row PR21 of the second display panel 220 substantially non-light-emitting.

[0069] At Figure 8 In the fifth embodiment shown, the signal source 130 adopts the following... Figure 4The control method of the embodiment shown, that is, in addition to executing the signal source 130, is as follows: Figure 7 In addition to the operation of the illustrated embodiment, the configuration further includes: pixels PX in the first pixel rows PR11 and PR21 operating in an intermittent light-emitting mode; the second pixel row PR12 of the first display panel 110 being substantially non-light-emitting; the first color light-emitting element E1 in the second pixel row PR22 of the second display panel 220 operating in an intermittent light-emitting mode; and other color light-emitting elements in the second pixel row PR22 of the second display panel 220 being substantially non-light-emitting. This operation, combined with color leakage elimination and seam compensation mechanisms, can achieve the effects of visually reducing or eliminating the seam width W and maintaining white balance, even on horizontally mirrored panels. In other embodiments, the aforementioned control functions of the signal source 130 on the first display panel 110 can be performed by the first control circuit 112, and the aforementioned control functions of the signal source 130 on the second display panel 220 can be performed by the second control circuit 122.

[0070] At Figure 9 In the sixth embodiment shown, the signal source 130 adopts the following... Figure 5 The control method of the embodiment shown, that is, in addition to executing the signal source 130, is as follows: Figure 8 In addition to the operation of the illustrated embodiment, the first color light-emitting element E1 in the third pixel row PR23 of the second display panel 220 is further configured to be substantially non-light-emitting. This operation aims to solve the problem of adjacent monochrome colors that may occur outside the splice seam G (between the second pixel row PR22 and the third pixel row PR23) after brightness compensation (seam compensation), ensuring the color uniformity of the overall image. In other embodiments, the aforementioned control functions of the signal source 130 on the second display panel 220 may be performed by the second control circuit 122.

[0071] From the detailed description of the specific embodiments disclosed above, it is clear that in the display device disclosed herein, to solve the technical problem of adjacent monochrome light-emitting elements and obvious color shift caused by the splicing seam of a display panel containing staggered pixels due to the first side splicing, this disclosure uses a signal source or control circuit to make the first color light-emitting element in the first pixel row adjacent to the splicing seam of one of the display panels substantially non-emitting. This transforms the originally identical light-emitting elements on both sides of the splicing seam into opposite different color light-emitting elements, achieving the technical effect of eliminating or reducing monochrome color leakage in the splicing seam, while avoiding the increased manufacturing costs caused by designing two completely different panels. Furthermore, by increasing the brightness of the pixels in the first pixel row adjacent to the splicing seam and combining the pixels to operate in an intermittent light-emitting mode, while turning off or adjusting the state of the light-emitting elements in the adjacent second pixel row, the technical effect of visually reducing or eliminating the seam width can be achieved by utilizing brightness overflow. This method addresses the monochrome adjacent problem that may occur in the outermost pixel rows after splicing seam compensation. In this case, the first color light-emitting elements in a specific pixel row can be further turned off to ensure color uniformity outside the splicing seam. Furthermore, this disclosure also provides a cost-saving solution: even if the pixel arrangement patterns of the panels are horizontally mirrored, two panels with similar structures can be produced by using a backplate with the same circuit layout and by interchanged positions of the second and third color light-emitting elements, thereby effectively saving photomask and manufacturing costs.

[0072] Although the present disclosure has been described above with reference to embodiments, it is not intended to limit the present disclosure. Anyone skilled in the art may make various modifications and alterations without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the appended claims.
