Abstract
Description
Splicing self-powered display devices and display equipment Technical Field
[0001] This disclosure relates to a display device and display apparatus, and more particularly to a self-powered display device and display apparatus composed of multiple display modules spliced together. Background Technology
[0002] To meet the market demand for commercial display billboards, many manufacturers are dedicated to developing ultra-large display devices. However, when the size requirement exceeds the limitation of a single display (e.g., large advertising billboards), it is necessary to combine multiple small displays into a larger display screen. Therefore, splicing technology must be relied upon to overcome the limitations of a single display size.
[0003] Currently, liquid crystal displays (LCDs) are the most common type of splicing display unit. However, LCDs require a backlight module to provide a light source. Due to the structural design of the backlight module, each LCD must have a mechanical bezel. This mechanical bezel is difficult to shrink, resulting in it remaining clearly visible at the splicing point. Consequently, the spliced image is not easily integrated, affecting the display effect of the splicing device. Furthermore, if self-powered displays are used as splicing units, the solar modules behind each self-powered display need to be connected in series or parallel during splicing, increasing the complexity of the entire display device and reducing its flexibility and convenience.
[0004] In view of this, developing a splicing display device that improves the display quality and reduces the complexity of splicing has become the goal of relevant companies.

Detailed Implementation
[0031] The various embodiments of this disclosure will be discussed in more detail below. However, this embodiment can be an application of various disclosed concepts and can be implemented in various different specific scopes. The specific embodiments are for illustrative purposes only and are not limited to the scope of disclosure. Furthermore, for the sake of simplicity in the drawings, some conventional structures and elements will be shown in a simple schematic manner in the drawings, and repeated elements may be represented by the same or similar numbers.
[0032] Please refer to Figure 1, which is a perspective view of a self-powered splicing display device according to one embodiment of the present disclosure. The self-powered splicing display device 100 includes a power generation module 110, at least two display modules 120, and at least two connectors 130.
[0033] Please refer to Figure 2, which is an exploded view of the self-powered splicing display device shown in Figure 1. Specifically, the power generation module 110 has a first surface 110a. The display modules 120 are arranged adjacent to each other on the first surface 110a, and each display module 120 is electrically connected to the power generation module 110. Therefore, in addition to providing power, the power generation module 110 can also serve as a splicing carrier for multiple display modules 120. This simplifies the existing method of splicing multiple self-powered displays, which requires connecting the power generation modules on their backs in series or parallel, reducing the complexity of the manufacturing process. Furthermore, the stacked structural design reduces the overall volume of the self-powered splicing display device 100. Moreover, multiple display modules 120 can share the same power generation module 110, thus reducing the cost of installing the power generation module 110.
[0034] The power generation module 110 may be a silicon crystal solar power generation module, a thin film solar power generation module, an organic solar power generation module, a perovskite solar power generation module, or a dye-sensitized solar power generation module, or other photoelectric conversion modules that can convert external light into electrical energy.
[0035] Please refer to Figure 3, which is a front view of the power generation module and display module in Figure 1. Each display module 120 may have a non-transparent portion 121 and a transparent portion 122, and the non-transparent portion 121 may be disposed around the transparent portion 122. For example, each display module 120 may be generally rectangular, so the non-transparent portion 121 may be generally rectangular and surround the transparent portion 122. The non-transparent portion 121 of the display module 120 may be provided with wiring for electrical connection between the display module 120 and external components and for signal transmission.
[0036] The power generation module 110 may include multiple power generation units 111, which can be electrically connected to each other. The power generation units 111 can be located in a projection area of the light-transmitting portion 122 projected onto the power generation module 110, thereby preventing the power generation units 111 from being blocked by the non-light-transmitting portion 121 and affecting their power generation efficiency. Furthermore, the power generation units 111 can be arranged in an array in the projection area, and the power generation units 111 can be electrically connected to the circuitry within the non-light-transmitting portion 121 to uniformly absorb external light for photoelectric conversion and directly provide power to the display module 120, thus simplifying the circuit configuration. However, this disclosure is not limited to the arrangement or number of the power generation units 111 or the way they are electrically connected to the display module 120.
[0037] Each of the display modules 120 has at least one adjacent edge and at least one non-adjacent edge. The adjacent edge of any display module 120 is arranged adjacent to the adjacent edge of another display module 120, and the non-adjacent edge of any display module 120 is not adjacent to another display module 120. Taking Figure 1 as an example, the display module 120 in the upper left corner has four edges, of which the edges adjacent to the display modules 120 in the upper right corner and the lower left corner are adjacent edges, and the other two edges are non-adjacent edges.
[0038] Connectors 130 are electrically connected to each display module 120, and each connector 130 is connected to a non-adjacent edge of the display module 120. Taking Figure 1 as an example, connector 130 connects two non-adjacent edges of the display module 120 and extends away from the display module 120. With the above structural configuration, there is no need to set connectors 130 between adjacent display modules 120, so the spacing D between adjacent display modules 120 can be less than 3mm, and there are no other frame structures between display modules 120, which can reduce the splicing gap and improve the display effect. In addition, each connector 130 can be a flexible circuit board, but this disclosure is not limited to this.
[0039] Different numbers of display modules 120 can be disposed on the first surface 110a of the self-powered splicing display device 100, and when the number of display modules 120 increases, the display modules 120 can be arranged in an array. The number of display modules 120 can be two, and the two display modules 120 can be arranged in a 1×2 or 2×1 manner on the first surface 110a. Alternatively, the number of display modules 120 can be four, and the four display modules 120 can be arranged in a 2×2 manner on the first surface 110a, so as to adjust the number and arrangement of display modules 120 according to the usage requirements and achieve the effect of dual-sided driving.
[0040] It should be noted that in the self-powered splicing display device 100 disclosed herein, each display module 120 only requires one edge connecting member 130 to be driven. Therefore, in other embodiments, the number of display modules can be N (N is a positive integer), and the N display modules can be arranged in a 1×N or N×1 manner and disposed on the first surface of the power generation module; or, the number of display modules can be 2M (M is a positive integer), and the 2M display modules can be arranged in a 2×M or M×2 manner and disposed on the first surface of the power generation module. In the above arrangement, each display module has one edge that is not adjacent to other display modules, so as to provide a connecting member for connection and achieve the effect of single-sided driving.
[0041] Each display module 120 can be a cholesteric liquid crystal display module. The difference in optical reflectance between any two display modules 120 can be less than or equal to 10%, the difference in contrast ratio between any two display modules 120 can be less than or equal to 20%, and the color difference between any two display modules 120 can be less than 5. This reduces the display differences between different display modules 120, thereby making the brightness and color of the displayed image more uniform.
[0042] Furthermore, the self-powered splicing display device 100 may include a frame (not shown), and the frame may surround the power generation module 110 and the display module 120. That is, the frame may cover the edges of the power generation module 110 and the display module 120 that are not spliced, so as to provide appropriate protection. On the other hand, although the display module 120 still has a line area that does not display images, the width of the line area is significantly reduced compared to the width of the existing mechanical frame. Therefore, the spliced image is more aesthetically pleasing. Moreover, the present disclosure does not require a mechanical frame to be set around each display module 120. Only a single frame needs to be set around the spliced self-powered display device 100 to achieve a good protection effect.
[0043] Furthermore, the splicing self-powered display device 100 may also include an adhesive layer (not shown), and the adhesive layer may be bonded between the power generation module 110 and the display module 120. The adhesive layer may be an optical adhesive layer to provide a good fixing effect.
[0044] Please refer to Figures 4 and 5. Figure 4 is an exploded view of a self-powered splicing display device according to another embodiment of this disclosure, and Figure 5 is a side view of the power generation module and display module of Figure 4. The self-powered splicing display device 200 includes a power generation module 210, at least two first display modules 220, at least two second display modules 240, and at least four connectors 230.
[0045] In detail, the power generation module 210 has a first surface 210a and a second surface 210b opposite to each other. The first display modules 220 are arranged adjacent to each other and disposed on the first surface 210a, and the second display modules 240 are arranged adjacent to each other and disposed on the second surface 210b. The remaining structural features of the power generation module 210, the first display module 220, the second display module 240 and the connector 230 are the same as or similar to those of the power generation module 110, the display module 120 and the connector 130 of the previous embodiment, and will not be described again here.
[0046] A first spacing D1 between adjacent first display modules 220 is less than 3mm, and a second spacing D2 between adjacent second display modules 240 is less than 3mm. Therefore, the self-powered splicing display device 200 can have the capability of double-sided display, and both display modules have tiny splicing gaps, thus increasing the applicability and aesthetic appeal of the self-powered splicing display device 200.
[0047] Furthermore, since external light can enter the power generation module 210 through the first display module 220 or the second display module 240, external light on one side of the self-powered display device 200 may affect the display effect on the other side. Therefore, the power generation module 210 may include multiple light-shielding parts (not shown) to block external light from penetrating. The light-shielding parts can be disposed between the power generation units. For example, light-shielding parts can be disposed on the parts of the power generation module 210 that do not have power generation units, and the light-shielding parts can also overlap with the power generation units to prevent light from passing through the spaces between the power generation units. In this way, the double-sided display effect of the self-powered display device 200 can be further improved.
[0048] Please refer to Figure 6, which is a front view schematic diagram of a display device according to another embodiment of the present disclosure. The display device 300 includes a plurality of the aforementioned self-powered splicing display devices 100 and 200, wherein the self-powered splicing display devices 100 and 200 are arranged adjacent to each other on a plane. Here, we take the self-powered splicing display device 100 as an example. As shown in Figure 6, the display device 300 may have a border F only at the connection points of different self-powered splicing display devices 100, thereby reducing the splicing gaps on the screen of the display device 300 and making the displayed image more complete.
[0049] In summary, the self-powered splicing display device disclosed herein simplifies the circuit connections between the power generation modules of existing self-powered splicing displays by arranging the display modules adjacent to each other and placing them on the power generation module. This also reduces the overall size of the self-powered splicing display device, achieving the effects of simplified manufacturing, reduced costs, and miniaturization. Furthermore, this structural configuration reduces the gaps between the display modules, decreasing the area of the gaps on the display screen and thus increasing the aesthetic appeal of the self-powered splicing display device.
[0050] Although the present disclosure has been presented above with reference to embodiments, it is not intended to limit the present disclosure. Any person 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.
