Detailed Implementation

[0017] The present invention can be understood by referring to the following detailed description in conjunction with the accompanying drawings. It should be noted that, for ease of understanding and for the sake of brevity, many of the accompanying drawings depict only a portion of the device, and specific elements in the drawings are not drawn to scale. Furthermore, the number and dimensions of the elements in the drawings are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0018] Throughout this specification and the appended claims, certain terms are used to refer to specific elements. Those skilled in the art will understand that electronic device manufacturers may use different names to refer to the same elements. This invention is not intended to distinguish between elements that have the same function but different names.

[0019] In the specification and claims of this invention, the words "containing" and "including" are open-ended terms, and therefore should be interpreted as "containing but not limited to...".

[0020] It should be understood that when an element or film is referred to as being "on" or "connected" to another element or film, it can be directly on or directly connected to the other element or film, or there may be an inserted element or film between them (indirect cases). Conversely, when an element is referred to as being "directly" on or "directly connected" to another element or film, there may be no inserted element or film between them. When an element or film is referred to as being "electrically connected" to another element or film, it can be interpreted as a direct electrical connection or a non-direct electrical connection. The electrical connection or coupling described in this invention can refer to a direct connection or an indirect connection. In the case of a direct connection, the endpoints of the two circuit components are directly connected or interconnected by a conductor segment, while in the case of an indirect connection, there may be a switch, diode, capacitor, inductor, resistor, other suitable components, or combinations of the above components between the endpoints of the two circuit components, but not limited to these.

[0021] Although the terms "first," "second," "third," etc., can be used to describe various constituent elements, the constituent elements are not limited by these terms. These terms are used only to distinguish a single constituent element from other constituent elements in the specification. The same terms may not be used in the claims, but rather replaced by "first," "second," "third," etc., according to the order of the elements declared in the claims. Therefore, in this specification, a first constituent element may be a second constituent element in a claim.

[0022] In this invention, the thickness, length and width can be measured by using an optical microscope, while the thickness or width can be measured by cross-sectional images from an electron microscope, but are not limited thereto.

[0023] Furthermore, there may be a certain degree of error between any two values ​​or directions used for comparison. The terms "approximately," "substantially," or "roughly" are generally interpreted as being within ±10% of the given value, or within ±5%, ±3%, ±2%, ±1%, or ±0.5% of the given value.

[0024] In addition, the terms "given range is from the first value to the second value" and "given range falls within the range of the first value to the second value" indicate that the given range includes the first value, the second value, and other values ​​in between.

[0025] If the first direction is perpendicular to the second direction, the angle between the first direction and the second direction can be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction can be between 0 degrees and 10 degrees.

[0026] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It is understood that these terms, for example, as defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant art and this invention, and should not be interpreted in an idealized or overly formal manner, unless specifically defined in the embodiments of this invention.

[0027] It should be understood that the technical features of several different embodiments can be replaced, reorganized, or mixed to complete other embodiments without departing from the spirit of the present invention.

The electronic device of the present invention may be various combinations of the above-mentioned devices, such as a combination of a display device and other devices, but is not limited thereto.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a top view schematic diagram of the display device according to the first embodiment of the present invention. Figure 2This is a top view schematic diagram of a spliced ​​display device assembled from the display devices of the first embodiment of the present invention. The display device DD may include a first display panel DP1. The first display panel DP1 may include a self-emissive display panel or a non-self-emissive display panel. The self-emissive display panel includes, for example, a light-emitting diode display panel, and the non-self-emissive display panel includes, for example, a liquid crystal display panel, but is not limited thereto. According to this embodiment, the first display panel DP1 includes a first display portion A1 and a first peripheral portion B1. The first peripheral portion B1 is disposed on at least one side of the first display portion A1, or in other words, the first peripheral portion B1 is disposed along at least one side of the first display portion A1. Furthermore, the first peripheral portion B1 does not correspond to at least one side of the first display portion A1, or in other words, at least one side of the first display portion A1 is not provided with the first peripheral portion B1. In other words, the first peripheral portion B1 is not adjacent to at least one side of the first display portion A1. For example, as Figure 1 As shown, the first display portion A1 may have a rectangular shape in the top view direction (i.e., direction Z) of the first display panel DP1 and includes side SL1, side SL2, side SL3, and side SL4. The first peripheral portion B1 may be disposed along side SL1, but does not correspond to side SL2, side SL3, and side SL4, but is not limited thereto. In some embodiments, the first peripheral portion B1 may be disposed along multiple sides of the first display portion A1, for example, along any one, two, or three of side SL1, side SL2, side SL3, and side SL4, and is not adjacent to at least one side of the first display portion A1. In some embodiments, the first display portion A1 may have any suitable shape in the top view direction of the first display panel DP1, and the first peripheral portion B1 may not be adjacent to at least a portion of the outer edge of the first display panel DP1. The first display portion A1 may be the portion of the first display panel DP1 used for the main display screen or that can be operated by the user, while the first peripheral portion B1 may be used to set peripheral elements.

[0030] In this embodiment, multiple display panels can be spliced ​​together to form a splicing display device. For example, Figure 2A splicing display device TD formed by splicing two display panels (first display panel DP1 and second display panel DP2) is shown, but is not limited thereto. According to this embodiment, in the manufacturing process of the splicing display device TD, the splicing display device TD can be formed by splicing at least one side of the display portion of a display panel that is not adjacent to (or corresponds to) its peripheral portion (or in other words, does not have a peripheral portion) with another display panel. Specifically, the two display panels can be spliced ​​by contacting one side of the display portion of a display panel that is not adjacent to its peripheral portion with another side of the display portion of a display panel that is not adjacent to its peripheral portion, or by bringing these two sides close to each other. In this case, the splicing requirement can be achieved by rotating the display panels during the splicing process. For example, as... Figure 2As shown, the splicing display device TD may include a first display panel DP1 and a second display panel DP2. The first display panel DP1 includes a first display portion A1 and a first peripheral portion B1, and the second display panel DP2 includes a second display portion A2 and a second peripheral portion B2. The splicing display device TD can be formed by splicing the first display panel DP1 and the second display panel DP2 together, but this is not a limitation. The positional characteristics of the second display portion A2 and the second peripheral portion B2 in the second display panel DP2 can be referred to the above description of the first display panel DP1, but are not limited thereto. In some embodiments, the size or position of the second peripheral portion B2 of the second display panel DP2 may differ from that of the first peripheral portion B1 of the first display panel DP1. For example, the second display portion A2 may have a rectangular shape in the top view (i.e., direction Z) of the second display panel DP2 and include side edges SL5, SL6, SL7, and SL8. The second peripheral portion B2 may be disposed along side edge SL5, but does not correspond to side edges SL6, SL7, and SL8, but is not limited thereto. In this case, there is a splicing edge TP between the first display panel DP1 and the second display panel DP2, and the first peripheral portion B1 and the second peripheral portion B2 are not disposed corresponding to the splicing edge TP. That is, in the top view (i.e., direction Z) of the splicing display device TD, the first peripheral portion B1 and the second peripheral portion B2 do not overlap with the splicing edge TP. The splicing edge TP may, for example, refer to the side edge of the first display panel DP1 used for splicing other display panels (i.e., side edge SL2) or the side edge of the second display panel DP2 used for splicing other display panels (i.e., side edge SL6). That is, the first display portion A1 of the first display panel DP1 may be adjacent to or in contact with the second display portion A2 of the second display panel DP2, and the first display portion A1 and the second display portion A2 do not include the surrounding portion. It should be noted that the splicing display device TD can be composed of more than two display panels spliced ​​together, and is not limited to... Figure 2 The structure shown is limited. Specifically, multiple sides of the display portion of a display panel that are not adjacent to its periphery can be used to splice with another display panel. For example, Figure 2 Sides SL3 and SL4 of the first display panel DP1 and side SL7 and SL8 of the second display panel DP2 can also be used for splicing with other display panels.

[0031] Return to reference Figure 1According to this embodiment, the first display panel DP1 further includes a plurality of first units E1 disposed in the first display portion A1. The first units E1 can be arranged in a matrix, for example... Figure 1 The first display portion A1 may have multiple first units E1 arranged in a 4x4 matrix along the X and Y directions, but this is not a limitation. Specifically, the first display portion A1 may consist of multiple first units E1 arranged in a matrix. The number of first units E1 in the first display portion A1 is not limited to... Figure 1 The area shown is for illustrative purposes only. In this case, the region of the first display portion A1 can be defined by the first unit E1. For example, the region of the first display portion A1 can be defined as the region enclosed by the outer edge of the outermost first unit E1, but is not limited thereto. A first unit E1 can be a pixel unit in the first display portion A1, or it can include a pixel area PR. In other words, the first display portion A1 is composed of multiple pixel units arranged in a matrix.

[0032] According to this embodiment, the pixel area PR in the first unit E1 may include six sub-pixel areas, namely sub-pixel area SPR1, sub-pixel area SPR2, sub-pixel area SPR3, sub-pixel area SPR4, sub-pixel area SPR5, and sub-pixel area SPR6. Sub-pixel area SPR1 is electrically connected to sub-pixel area SPR2, sub-pixel area SPR3 is electrically connected to sub-pixel area SPR4, and sub-pixel area SPR5 is electrically connected to sub-pixel area SPR6. Specifically, sub-pixel areas SPR1 and SPR2 can be connected in parallel, sub-pixel areas SPR3 and SPR4 can be connected in parallel, and sub-pixel areas SPR5 and SPR6 can be connected in parallel. Sub-pixel areas SPR1 and SPR2 can be sub-pixel areas of a first color, wherein one of sub-pixel areas SPR1 and SPR2 is a display sub-pixel area of ​​the first color, used to display light of the first color, and the other of sub-pixel areas SPR1 and SPR2 is a spare sub-pixel area of ​​the first color. Similarly, sub-pixel areas SPR3 and SPR4 can be sub-pixel areas of a second color, wherein one of sub-pixel areas SPR3 and SPR4 is a display sub-pixel area of ​​the second color, and the other of sub-pixel areas SPR3 and SPR4 is a spare sub-pixel area of ​​the second color; sub-pixel areas SPR5 and SPR6 can be sub-pixel areas of a third color, wherein one of sub-pixel areas SPR5 and SPR6 is a display sub-pixel area of ​​the third color, and the other of sub-pixel areas SPR5 and SPR6 is a spare sub-pixel area of ​​the third color. In this embodiment, the first color, the second color, and the third color can be red, green, and blue, respectively, but are not limited thereto. In other words, the pixel area PR of the first unit E1 can include sub-pixels of three colors, and each color sub-pixel can include two sub-pixel areas electrically connected (in parallel) to each other. For example, as Figure 1 As shown, sub-pixel areas SPR1, SPR3, and SPR5 in pixel area PR can be display sub-pixel areas, such as red display sub-pixel area, green display sub-pixel area, and blue display sub-pixel area, respectively. Sub-pixel areas SPR2, SPR4, and SPR6 in pixel area PR can be spare sub-pixel areas, such as red spare sub-pixel area, green spare sub-pixel area, and blue spare sub-pixel area, respectively, but are not limited to this.

[0033] In the above scenario, sub-pixel regions SPR1, SPR3, and SPR5 each have at least one light-emitting unit, or in other words, the light-emitting units can be configured corresponding to sub-pixel regions SPR1, SPR3, and SPR5. For example, ... Figure 1As shown, sub-pixel area SPR1 may have a light-emitting unit LU1, sub-pixel area SPR3 may have a light-emitting unit LU2, and sub-pixel area SPR5 may have a light-emitting unit LU3. The light-emitting unit may include, but is not limited to, light-emitting diodes (LEDs). LEDs may include organic light-emitting diodes (OLEDs) or in-organic light-emitting diodes (IN-OLEDs). Inorganic LEDs may include mini LEDs, micro LEDs, or quantum dot LEDs. The light-emitting units may not correspond to the spare sub-pixel areas (sub-pixel areas SPR2, SPR4, and SPR6). It should be noted that although the light-emitting units may not correspond to the spare sub-pixel areas, the color of the spare sub-pixel area can be determined by the display sub-pixel area to which it is electrically connected. In some embodiments, light-emitting units LU1, LU2, and LU3 can emit red, green, and blue light respectively, causing sub-pixel areas SPR1, SPR3, and SPR5 to display red, green, and blue light respectively. In other embodiments, light-emitting units LU1, LU2, and LU3 can emit light of the same color, such as blue light, and the first display panel DP1 may further include light conversion layers respectively corresponding to sub-pixel areas SPR1 and SPR3 for converting light into red and green light. It should be noted that the positions of the sub-pixel areas displayed in the pixel areas PR are not fixed. Figure 1 The examples shown are for illustrative purposes only. In some embodiments, such as Figure 2As shown in the second display panel DP2, sub-pixel areas SPR2, SPR4, and SPR6 can be display sub-pixel areas, for example, red display sub-pixel area, green display sub-pixel area, and blue display sub-pixel area, respectively, while sub-pixel areas SPR1, SPR3, and SPR5 can be spare sub-pixel areas, for example, red spare sub-pixel area, green spare sub-pixel area, and blue spare sub-pixel area, respectively. In some embodiments, any one of sub-pixel areas SPR1 and SPR2, any one of sub-pixel areas SPR3 and SPR4, and any one of sub-pixel areas SPR5 and SPR6 can be selected as display sub-pixel areas. In some embodiments, sub-pixel areas SPR1 and SPR2 can both be provided with light-emitting units, and the brightness of the light-emitting unit corresponding to sub-pixel area SPR1 can be the same as or different from the brightness of the light-emitting unit corresponding to sub-pixel area SPR2. Similarly, sub-pixel areas SPR3 and SPR4 can both be provided with light-emitting units, and the brightness of the light-emitting unit corresponding to sub-pixel area SPR3 can be the same as or different from the brightness of the light-emitting unit corresponding to sub-pixel area SPR4; sub-pixel areas SPR5 and SPR6 can both be provided with light-emitting units, and the brightness of the light-emitting unit corresponding to sub-pixel area SPR5 can be the same as or different from the brightness of the light-emitting unit corresponding to sub-pixel area SPR6. In this embodiment, the sizes of sub-pixel areas of different colors can be the same or different. For example, the sizes of sub-pixel areas SPR1 (or SPR2), SPR3 (or SPR4), and SPR5 (or SPR6) can be the same or different from each other. Furthermore, within a pixel area PR, the sizes of two sub-pixel areas of the same color can be the same. For example, the size of subpixel area SPR1 can be the same as the size of subpixel area SPR2, the size of subpixel area SPR3 can be the same as the size of subpixel area SPR4, and the size of subpixel area SPR5 can be the same as the size of subpixel area SPR6. The "size of subpixel area" mentioned above may refer to the area of ​​the subpixel area in the top view of the display panel (or splicing display device TD), but is not limited thereto.

[0034] According to this embodiment, sub-pixel areas SPR1, SPR3, and SPR5 are arranged in a certain manner along a first direction DR1, while sub-pixel areas SPR2, SPR4, and SPR6 are arranged in the same manner in a direction opposite to the first direction DR1. Here, "arrangement of sub-pixel areas" may refer, for example, to the order in which the sub-pixel areas are arranged. For example, such as... Figure 1As shown, sub-pixel areas SPR5, SPR3, and SPR1 are arranged sequentially along the first direction DR1, while sub-pixel areas SPR6, SPR4, and SPR2, which are electrically connected to sub-pixel areas SPR5, SPR3, and SPR1 respectively, are arranged sequentially along a direction opposite to the first direction DR1. In this embodiment, the first direction DR1 can be direction Y, that is, sub-pixel areas SPR5, SPR3, and SPR1 are arranged sequentially along direction Y, while sub-pixel areas SPR6, SPR4, and SPR2 are arranged sequentially along direction -Y. That is, the arrangement direction of sub-pixel areas SPR1, SPR3, and SPR5 is opposite to the arrangement direction of sub-pixel areas SPR2, SPR4, and SPR6. Furthermore, in a second direction DR2 (i.e., direction X) perpendicular to the first direction DR1, sub-pixel region SPR1 can be adjacent to sub-pixel region SPR6, sub-pixel region SPR2 can be adjacent to sub-pixel region SPR5, and sub-pixel region SPR3 can be adjacent to sub-pixel region SPR4, but this is not a limitation. It should be noted that although... Figure 1 The diagram illustrates the interconnected structure of sub-pixel regions within the pixel region PR, but this embodiment is not limited thereto. In some embodiments, the sub-pixel regions within the pixel region PR may be separated from each other. In some embodiments (e.g.) Figure 3 and Figure 4As shown), the first direction DR1 mentioned above can be direction X, that is, sub-pixel areas SPR5, SPR3, and SPR1 are arranged sequentially along direction X, while sub-pixel areas SPR6, SPR4, and SPR2 are arranged sequentially along direction -X. It should be noted that the "arrangement of sub-pixel areas" in this invention can be determined, for example, based on the arrangement of the colors of the light-emitting units in the sub-pixel areas and the design of the wiring in the sub-pixel areas (used to determine the spare sub-pixel areas corresponding to (or electrically connected to) each color's display sub-pixel area), and is not limited to the arrangement / distribution of the electrodes (e.g., p-electrode or n-electrode) of the light-emitting units or the bonding pads used to connect the electrodes. For example, the arrangement / distribution of the bonding pads used to connect with the electrodes of the light-emitting units in sub-pixel areas SPR5, SPR3, and SPR1 can be the same as or different from the arrangement / distribution of the bonding pads used to connect with the electrodes of the light-emitting units in sub-pixel areas SPR6, SPR4, and SPR2. In some embodiments, the bonding pads for bonding with the electrodes of the light-emitting unit in the electrically connected sub-pixel regions (e.g., sub-pixel regions SPR1 and SPR2, SPR3 and SPR4, or SPR5 and SPR6) are arranged in the same manner. In some embodiments, the bonding pads for bonding with the electrodes of the light-emitting unit in sub-pixel regions corresponding to different colors (e.g., sub-pixel regions SPR5, SPR3, and SPR1) may be arranged in the same or different manner.

[0035] According to this embodiment, through the above arrangement design, the arrangement of multiple sub-pixel regions in the pixel region PR has rotational symmetry. Specifically, the color distribution of the sub-pixel regions in the pixel region PR can have rotational symmetry. For example... Figure 1As shown, through the above arrangement design, a pixel area PR can include two rows of sub-pixel areas, namely, a first row of sub-pixel areas G1 on the left and a second row of sub-pixel areas G2 on the right. The sub-pixel areas in the first row G1 (i.e., sub-pixel areas SPR1, SPR3, and SPR5) have a color order in the first direction DR1 (in this embodiment, for example, blue, green, and red, but not limited thereto). The sub-pixel areas in the second row G2 (i.e., sub-pixel areas SPR2, SPR4, and SPR6) can also have this color order in a direction opposite to the first direction DR1. That is, when viewed in the same direction, the color order of the sub-pixel areas in the first row G1 is the reverse of the color order of the sub-pixel areas in the second row G2. In other words, in the first direction DR1, the sub-pixel areas in the first row of sub-pixel areas G1 are observed to be, in order, blue sub-pixel area (i.e., sub-pixel area SPR5), green sub-pixel area (i.e., sub-pixel area SPR3), and red sub-pixel area (i.e., sub-pixel area SPR1). Similarly, in the opposite direction of DR1, the sub-pixel areas in the second row of sub-pixel areas G2 are observed to be, in order, blue sub-pixel area (i.e., sub-pixel area SPR6), green sub-pixel area (i.e., sub-pixel area SPR4), and red sub-pixel area (i.e., sub-pixel area SPR2). In this case, Figure 1After the first display panel DP1 is rotated 180 degrees, the sub-pixel areas in the second row of sub-pixel areas G2 on the left side of pixel area PR are, in the first direction DR1, a blue sub-pixel area (i.e., sub-pixel area SPR6), a green sub-pixel area (i.e., sub-pixel area SPR4), and a red sub-pixel area (i.e., sub-pixel area SPR2). Meanwhile, the sub-pixel areas in the first row of sub-pixel areas G1 on the right side are, in the opposite direction to DR1, a blue sub-pixel area (i.e., sub-pixel area SPR5), a green sub-pixel area (i.e., sub-pixel area SPR3), and a red sub-pixel area (i.e., sub-pixel area SPR1), exhibiting the same color distribution as the sub-pixel areas of pixel area PR observed before the rotation of the first display panel DP1. In short, through the above sub-pixel area arrangement design, the color arrangement of the sub-pixel areas in pixel area PR observed when the first display panel DP1 is not rotated and after rotating the first display panel DP1 by 180 degrees can be the same. This situation can be referred to in this paper as the sub-pixel area arrangement exhibiting rotational symmetry at a rotation angle of 180 degrees. It should be noted that the arrangement of sub-pixel areas in this embodiment is not limited to rotational symmetry only at a rotation angle of 180 degrees. In some embodiments, the arrangement of sub-pixel areas may have rotational symmetry at a specific angle, wherein this specific angle may be greater than 0 degrees and less than 360 degrees, for example, 90 degrees, 180 degrees, or 270 degrees, depending on the rotation of the display panel when forming the splicing display device TD. Furthermore, the pixel area PR is not limited to including sub-pixels of three colors. In some embodiments, the pixel area PR may include sub-pixels of N colors (N>3), thereby including 2N sub-pixel areas, wherein the arrangement of these 2N sub-pixel areas has rotational symmetry. In some embodiments, as long as the arrangement of sub-pixel areas has rotational symmetry at a specific angle, the sub-pixel areas may have any suitable arrangement. The display panels in the splicing display device TD may all have the above-described sub-pixel area arrangement design.

[0036] Through the above-described sub-pixel arrangement design, even if the display panel is rotated during the process of forming the splicing display device TD (after rotation and splicing), the arrangement of the sub-pixel areas near the splicing edge TP can be approximately the same as the arrangement of the sub-pixel areas in other areas of the splicing display device TD (e.g., within each display panel). This reduces the possibility of uneven light source (mura) at the splicing edge TP, thereby improving the display quality of the splicing display device TD. Specifically, in this embodiment, multiple display panels can be provided first, and then these display panels can be rotated and spliced ​​to form the splicing display device TD, so that the display portions of different display panels can be spliced ​​on their sides that are not adjacent to the peripheral portions. The display panels used to form the splicing display device TD can all have the above-described sub-pixel area design, but their structures can be the same or different. The splicing display device TD formed in the above manner can, for example, include a transparent display device, whose front and back sides allow light to pass through so that users can observe the real environmental conditions. Since the splicing edge TP of the splicing display device TD does not have a peripheral portion, the display quality of the splicing display device TD can be improved. In existing display panels, if display panels are rotated and spliced ​​to form a splicing display device, the arrangement of sub-pixel areas in each display panel will differ due to rotation. This can cause the arrangement of sub-pixel areas near the splicing point of the splicing display device to differ from the arrangement of sub-pixel areas in other areas of the splicing display device. In this case, users may observe uneven brightness (mura) at the splicing point of the splicing display device, thereby affecting the display quality or visual effect of the splicing display device. In contrast, since the arrangement of sub-pixel areas in the display panels of this embodiment (e.g., the first display panel DP1 and the second display panel DP2) has rotational symmetry, the arrangement of sub-pixel areas in each area of ​​the splicing display device TD can be made approximately the same by setting the light-emitting units in suitable positions. For example, as Figure 2As shown, in the pixel region PR of the first display panel DP1, the light-emitting units may be respectively arranged corresponding to the sub-pixel regions SPR1, SPR3, and SPR5, while in the pixel region PR of the second display panel DP2, the light-emitting units may be respectively arranged corresponding to the sub-pixel regions SPR2, SPR4, and SPR6. Then, the second display panel DP2 can be rotated 180 degrees, and the first display panel DP1 and the second display panel DP2 can be spliced into a spliced display device TD in such a way that the side SL6 contacts the side SL2 or the side SL6 is adjacent to the side SL2. Thus, the first peripheral part B1 and the second peripheral part B2 are respectively located on opposite sides of the spliced display device TD. In this case, since the arrangement of the sub-pixel regions has rotational symmetry at a rotation angle of 180 degrees, the color order of the sub-pixel regions in the two pixel regions PR on both sides of the splicing edge TP of the spliced display device TD in the direction Y can be the same as that of the sub-pixel regions in other regions of the spliced display device TD (such as within each display panel), for example, in the order of blue, green, and red. That is, the sub-pixel regions located at various places in the spliced display device TD can be arranged in the same color order. In some embodiments, in the pixel region PR of the first display panel DP1, the light-emitting units may be respectively arranged corresponding to the sub-pixel regions SPR1, SPR4, and SPR5, while in the pixel region PR of the second display panel DP2, the light-emitting units may be respectively arranged corresponding to the sub-pixel regions SPR2, SPR3, and SPR6, that is, the red display sub-pixel regions, green display sub-pixel regions, and blue display sub-pixel regions in the pixel region PR may be arranged in a "pin" shape. Thus, the phenomenon of uneven brightness (mura) observed by the user at the splicing edge TP can be reduced, and further the display quality of the spliced display device TD can be improved. The rotation angle for making the arrangement of the sub-pixel regions have rotational symmetry in this embodiment can be determined according to the rotation angle of the display panel when the display panels are rotated and spliced into the spliced display device TD. For example, in this embodiment, the second display panel DP2 is rotated 180 degrees and then spliced with the first display panel DP1 to form the spliced display device TD. Therefore, the arrangement of the sub-pixel regions in the first display panel DP1 and the second display panel DP2 can be designed to have rotational symmetry at a rotation angle of 180 degrees, but this is not limited thereto.

[0037] Figure 2The splicing method shown is merely exemplary and is not limited to this embodiment. In some embodiments, the first display panel DP1 and the second display panel DP2 can be spliced ​​into a splicing display device TD by making side SL3 and side SL8 contact or adjacent to each other, or by making side SL4 and side SL7 contact or adjacent to each other. Thus, the first peripheral portion B1 and the second peripheral portion B2 are located on the same side of the splicing display device TD, that is, they are adjacent to each other. In this case, in the pixel area PR of the first display panel DP1 and the second display panel DP2, the light-emitting units can be respectively disposed corresponding to sub-pixel areas SPR1, SPR3, and SPR5, or respectively corresponding to sub-pixel areas SPR2, SPR4, and SPR6. In some embodiments, the first display panel DP1 and the second display panel DP2 can be spliced ​​into a splicing display device TD by making side SL3 and side SL7 contact or adjacent to each other, or by making side SL4 and side SL8 contact or adjacent to each other. In this case, the placement position of the light-emitting units in the sub-pixel areas can be referred to... Figure 2 As mentioned above, I will not repeat it here.

[0038] Please refer to Figures 3 to 5 , Figure 3 This is a partially enlarged top view of a display device according to a variation of the first embodiment of the present invention. Figure 4 This is a partially enlarged top view of a display device according to a variation of the first embodiment of the present invention. Figure 5 This is a cross-sectional schematic diagram of the wiring area according to the first embodiment of the present invention. Figure 3 and Figure 4 For example, a top view of a plurality of first units E1 of the first display panel DP1 is shown. According to this embodiment, as... Figure 3 , Figure 4As shown, the first unit E1 may include a trace area WR and a transparent area TR in addition to the pixel area PR described above. Specifically, the pixel area PR, trace area WR, and transparent area TR can be defined in the region of the first unit E1, or the region of the first unit E1 may be composed of the pixel area PR, trace area WR, and transparent area TR. The trace area WR may be the region corresponding to the signal lines, active elements, passive elements, or other conductive elements disposed in the first display portion A1 of the first display panel DP1. Signal lines may include scan lines, data lines, power lines, emission lines, or other signal lines applicable to the first display panel DP1. Active elements may include driving elements, switching elements, or other elements applicable to the first display panel DP1. Driving elements and switching elements include, for example, thin film transistors (TFTs), but are not limited thereto. Passive elements may include resistors, capacitors, inductors, etc., but are not limited thereto. Although not shown in the figure, in one embodiment, the first display panel DP1 may include a substrate and a circuit layer disposed on the substrate. The circuit layer may include a structure formed by stacking multiple conductive layers and multiple insulating layers, wherein the conductive layers may be used to form the signal lines, active components and passive components described above, but are not limited thereto. Figure 5 It shows Figure 3 The structure shown is a cross-sectional view along the tangent A-A', i.e. Figure 5 The cross-sectional structure of the routing area WR is shown. (See figure) Figure 5 As shown, in this embodiment, the trace area WR may include a first conductive layer C1, a second conductive layer C2, and a third conductive layer C3, wherein the second conductive layer C2 is disposed on the first conductive layer C1, and the third conductive layer C3 is disposed on the second conductive layer C2. The first conductive layer C1, the second conductive layer C2, and the third conductive layer C3 may be conductive layers in the aforementioned circuit layers, but are not limited thereto. Furthermore, although... Figure 5As not shown, insulating layers may be included between the conductive layers, and the first conductive layer C1 may be disposed on a substrate. The first conductive layer C1, the second conductive layer C2, and the third conductive layer C3 may comprise any suitable conductive material, such as a metallic material or a transparent conductive material. Metallic materials include, for example, titanium (Ti), aluminum (Al), molybdenum (Mo), copper (Cu), etc., but are not limited thereto. Transparent conductive materials include, for example, indium tin oxide (ITO), but are not limited thereto. The signal lines, active elements, and passive elements corresponding to the trace area WR described above may be formed by at least one layer of the first conductive layer C1, the second conductive layer C2, and the third conductive layer C3. For example, in one embodiment, the first conductive layer C1 may form a scan line or a transmit line, the second conductive layer C2 may form a data line, and the third conductive layer C3 may form a power line, but are not limited thereto. In one embodiment, the first conductive layer C1 may form the gate of a driving unit and / or a switching element (thin-film transistor), while the second conductive layer C2 may form the source and drain of the driving unit and / or the switching element. In some embodiments, the trace area WR may include more conductive layers, and not necessarily... Figure 5 The illustration is for illustrative purposes only. In this embodiment, the light-emitting unit disposed in the pixel region PR can be electrically connected to a component disposed in the trace region WR, such as a driving unit, to control the light emission of the light-emitting unit. For example, at least one signal line (e.g., a scan line) in the trace region WR can be electrically connected to the pixel region PR (or the light-emitting unit in the pixel region PR) and the driving unit (e.g., the drain of the driving unit) to electrically connect the light-emitting unit to the driving unit, but this is not a limitation. In this case, as shown... Figure 3 and Figure 4 As shown, from a top view, the trace area WR can be connected to the pixel area PR. Furthermore, in this embodiment, the drive unit can also be electrically connected, for example, to peripheral elements disposed in the peripheral portion. For example, such as... Figure 2As shown, the splicing display device TD may further include a first driving circuit board DC1 disposed in a first peripheral portion B1 of the first display panel DP1 and a second driving circuit board DC2 disposed in a second peripheral portion B2 of the second display panel DP2. The driving units in the first display panel DP1 may be electrically connected to the first driving circuit board DC1, and the driving units in the second display panel DP2 may be electrically connected to the second driving circuit board DC2, but this is not a limitation. The first driving circuit board DC1 and the second driving circuit board DC2 may, for example, include printed circuit boards (PCBs), but this is not a limitation. It should be noted that, although not shown in the figure, in some embodiments, the first display panel DP1 may include other opaque elements, which may correspond to the trace area WR. In this embodiment, the transmittance of the trace area WR may be less than 20%, but this is not a limitation. In some embodiments, the transmittance of the trace area WR may be less than 15%. In some embodiments, the transmittance of the trace area WR may be less than 10%.

[0039] According to this embodiment, the region of the first unit E1 corresponding to at least one of the conductive layers (e.g., the first conductive layer C1, the second conductive layer C2, and the third conductive layer C3) used to form the aforementioned signal lines, active components, and passive components can be defined as the trace area WR. In other words, at least one conductive layer can be observed at any position when viewing the trace area WR from above. Figure 5 Several examples of the stacking of conductive layers corresponding to the trace region WR are shown. In some embodiments, such as Figure 5 As shown in structure (I), the area of ​​the uppermost third conductive layer C3 in the conductive layer can substantially correspond to the area of ​​the trace region WR, or in other words, the size (e.g., area) of the third conductive layer C3 in the top view direction can be substantially the same as the size of the trace region WR in the top view direction. Furthermore, the first conductive layer C1 and the second conductive layer C2 can be patterned. In other words, the third conductive layer C3 can completely cover the first conductive layer C1 and the second conductive layer C2. In this case, the third conductive layer C3 can be observed at any position when viewing the trace region WR from above. In some embodiments, the uppermost third conductive layer C3 can be patterned and not correspond to a portion of the trace region WR, while at least one of the first conductive layer C1 and the second conductive layer C2 can correspond to that portion of the trace region WR. The first conductive layer C1 and the second conductive layer C2 can be patterned. In other words, the portion of the trace region WR that does not correspond to the third conductive layer C3 will still correspond to at least one of the first conductive layer C1 and the second conductive layer C2. For example, as... Figure 5As shown in structure (II), the third conductive layer C3 can be patterned without corresponding to a region R1 in the trace area WR, but the second conductive layer C2 can be corresponding to region R1. In this case, when viewing the trace area WR from above, the second conductive layer C2 (at the position corresponding to region R1) and the third conductive layer C3 (at the position not corresponding to region R1) can be observed. In some embodiments, as Figure 5 As shown in structure (III), the third conductive layer C3 can be patterned but does not correspond to a region R2 in the trace area WR. The second conductive layer C2 can be patterned and partially corresponds to region R2, such that a region R3 in the trace area WR does not correspond to the second conductive layer C2 and the third conductive layer C3, while the first conductive layer C2 can be patterned and corresponds to region R3. In this case, when viewing the trace area WR from above, the third conductive layer C3, the second conductive layer C2 (corresponding to region R2 but not to region R3), and the first conductive layer C1 (corresponding to region R3) can be observed. As can be seen from the above, the range of the trace area WR can be defined by the distribution area of ​​the conductive layers. Specifically, the region corresponding to the union of the orthographic projections of each conductive layer on the plane XY (or the substrate) can be the trace area WR, and the area of ​​this region can be the area of ​​the trace area WR.

[0040] As described above, the first conductive layer C1, the second conductive layer C2, and the third conductive layer C3 can be patterned, thereby including multiple conductive portions. For example, as... Figure 5 As shown in structure (III), the first conductive layer C1 can be patterned to include conductive portions P1 and P2 that are separated from each other and adjacent to each other. According to this embodiment, conductive portions P1 and P2 may have a distance D1 between them, wherein the distance D1 may be greater than or equal to 0.8 micrometers (μm) (i.e., D1 ≥ 0.8 μm), but is not limited thereto. The distance D1 can be defined as the minimum distance between conductive portions P1 and P2 in a cross-sectional view of the first display panel DP1 (or the splicing display device TD). In some embodiments, the distance D1 may be greater than or equal to 1 μm (i.e., D1 ≥ 1 μm). In some embodiments, the distance D1 may be greater than or equal to 1.2 μm (i.e., D1 ≥ 1.2 μm). By ensuring that the distance D1 falls within the above range, signal interference between different conductive portions in a conductive layer can be reduced, or the problem of short circuits between different conductive portions in a conductive layer due to dust or other objects during the manufacturing process can be reduced. It should be noted that the above features can be applied to any conductive layer, that is, the distance D1 can be the distance between two adjacent conductive parts of any conductive layer.

[0041] Furthermore, in the normal direction of the first display panel DP1 (or the splicing display device TD), a conductive layer may at least partially overlap another conductive layer adjacent to it. For example, as Figure 5As shown in structure (III), a portion P3 of the second conductive layer C2 may overlap with a third conductive layer C3 located on and adjacent to the second conductive layer C2. According to this embodiment, in a cross-sectional view of the first display panel DP1 (or splicing display device TD), the portion P3 may have a length L1, wherein the length L1 may be greater than or equal to 0.1 μm (i.e., L1 ≥ 0.1 μm). The length L1 can be considered as the length of the portion of two adjacent conductive layers overlapping each other. In some embodiments, the length L1 may be greater than or equal to 0.2 μm (i.e., L1 ≥ 0.2 μm). In some embodiments, the length L1 may be greater than or equal to 0.3 μm (i.e., L1 ≥ 0.3 μm). It should be noted that the above features can be applied to any two adjacent conductive layers. For example, in... Figure 5 In structure (III), a portion of the second conductive layer C2 may overlap the first conductive layer, and the length range of this portion may refer to the range of the length L1 mentioned above. By making the length L1 fall within the aforementioned range, the possibility of light leakage caused by light emanating in an oblique direction can be reduced, or the oblique light-blocking effect of the conductive layer can be improved.

[0042] It should be noted that the above descriptions of the characteristics of distance D1 and length L1 can also be applied to... Figure 5 The structures shown in structure (I) and structure (II) are as follows.

[0043] Return to reference Figure 3 and Figure 4 According to this embodiment, the transparent area TR can be defined as the area of ​​the first unit E1 other than the pixel area PR and the routing area WR. The transparent area TR can be adjacent to at least one of the pixel area PR and the routing area WR. Depending on the layout design of the components in the routing area WR, the transparent area TR can be divided into multiple separated parts, but is not limited thereto. For example, as Figure 3 As shown, the region of the first unit E1 may include multiple transparent portions, namely transparent portion T1 and transparent portion T2, and the combination of these transparent portions constitutes the region of the transparent region TR. Similarly, Figure 4The region of the first unit E1 may include transparent portions T1, T2, and T3, and the combination of these transparent portions constitutes the region of the transparent area TR. The transparent area TR may correspond to a portion of the first display panel DP1 that includes transparent or high-transmittance material. In this embodiment, the transmittance of the transparent area TR may be greater than or equal to 20%, but is not limited thereto. In some embodiments, the transmittance of the transparent area TR may be greater than or equal to 30%. In some embodiments, the transmittance of the transparent area TR may be greater than or equal to 40%. Furthermore, according to this embodiment, the area of ​​the transparent area TR may be greater than 33% of the area of ​​the first unit E1, but is not limited thereto. Here, "the area of ​​the transparent area TR and the area of ​​the first unit E1" may, for example, refer to the areas of the transparent area TR and the first unit E1 in the top-view direction, respectively. When the transparent area TR includes multiple transparent portions, the area of ​​the transparent area TR may be the sum of the areas of these transparent portions. For example, Figure 3 The area of ​​the transparent region TR can be the sum of the areas of the transparent portions T1 and T2. In some embodiments, the area of ​​the transparent region TR can be greater than 40% of the area of ​​the first unit E1. In some embodiments, the area of ​​the transparent region TR can be greater than 50% of the area of ​​the first unit E1. According to the above design, the light transmittance of the first unit E1 in this embodiment can be greater than or equal to 30%, but is not limited thereto. In some embodiments, the light transmittance of the first unit E1 can be greater than or equal to 40%, 60%, 70%, or 80%. In some embodiments, the light transmittance of the first unit E1 can be less than or equal to 90%.

[0044] In this embodiment, the shape of the first unit E1 in the top view direction may have rotational symmetry, but is not limited thereto. For example, Figure 3 The first unit E1 can be rectangular in shape when viewed from above. Or, Figure 4 The shape of the first unit E1 in the top view can be either windmill-shaped or dart-shaped. It should be noted that the shape of the first unit E1 in the top view is not limited to... Figure 3 and Figure 4 The shapes shown are limited to those described herein and may include other rotationally symmetrical shapes, such as circles, triangles, regular polygons, etc., but are not limited thereto. Furthermore, in this embodiment, the patterns of the wiring areas WR and / or transparent areas TR in different first units E1 may be identical or rotationally symmetrical in the top view, but are not limited thereto. Specifically, as shown... Figure 3 and Figure 4As shown, the pattern of the trace area WR in a first unit E1 can be identical to the pattern of the trace area WR in another first unit E1 adjacent to the first unit E1 in the X direction after being rotated 180 degrees. Furthermore, the pattern of the trace area WR in a first unit E1 can be identical to the pattern of the trace area WR in another first unit E1 adjacent to the first unit E1 in the Y direction. In some embodiments, the trace areas WR in different first units E1 may not have rotational symmetry due to different signal line layouts. Similarly, as... Figure 3 and Figure 4 As shown, the pattern of the transparent area TR in a first unit E1 can be identical to the pattern of the transparent area TR in another first unit E1 adjacent to the first unit E1 in the X direction after being rotated 180 degrees. Furthermore, the pattern of the transparent area TR in a first unit E1 can be identical to the pattern of the transparent area TR in another first unit E1 adjacent to the first unit E1 in the Y direction. In other words, the first display portion A1 of the first display panel DP1 in this embodiment can be composed of multiple first units E1 that are rotationally symmetrical to each other, but is not limited thereto. Through the above design, after the display panels are rotated and spliced ​​into a splicing display device TD, the structural consistency between the portion of the splicing display device TD near the splicing edge TP and other portions of the splicing display device TD can be improved, thereby improving the display quality of the splicing display device TD.

[0045] It should be noted that the structural features of the first display panel DP1 and its included first unit E1 described above can be applied to other display panels in the splicing display device TD (such as the second display panel DP2), and therefore will not be elaborated further. Furthermore, the above-mentioned... Figures 3 to 5 The structural and / or dimensional design of the first display panel DP1 shown can be applied to various embodiments and variations of the present invention.

[0046] Please refer to Figure 6 , Figure 6This is a top view schematic diagram of a splicing display device according to a second embodiment of the present invention. According to this embodiment, the pixel area PR of the first unit E1 of the first display portion A1 of the display panel (e.g., the first display panel DP1) in the splicing display device TD may include three sub-pixel areas, namely sub-pixel area SPR1, sub-pixel area SPR2, and sub-pixel area SPR3. Sub-pixel areas SPR1, SPR2, and SPR3 may be sub-pixel areas of three colors, for example, red, green, and blue sub-pixel areas respectively, but are not limited thereto. In some embodiments, the pixel area PR may include more than three sub-pixel areas. According to this embodiment, the sub-pixel areas in the first unit E1 of the first display panel DP1 may be arranged along a first direction DR1 (e.g., direction Y, but not limited thereto). According to this embodiment, in the first display panel DP1, the sub-pixel areas in each pixel area PR may have a first arrangement or a second arrangement. Specifically, as... Figure 6 As shown, the sub-pixel areas in pixel area PR of one of the first units E1 (e.g., first unit E11) can have a first arrangement in the first direction DR1 (e.g., direction Y, but not limited thereto). The first arrangement, for example, refers to the arrangement of three sub-pixel areas along the first direction DR1 (i.e., from bottom to top) as a blue sub-pixel area, a green sub-pixel area, and a red sub-pixel area. Furthermore, the sub-pixel areas in pixel area PR of another of the first units E1 (e.g., first unit E12) can have a second arrangement in the first direction DR1 (e.g., direction Y, but not limited thereto). The second arrangement, for example, refers to the arrangement of three sub-pixel areas along the first direction DR1 (i.e., from bottom to top) as a red sub-pixel area, a green sub-pixel area, and a blue sub-pixel area.

[0047] According to this embodiment, among the plurality of first units E1 arranged along the first direction DR1 in the first display panel DP1, the first arrangement and the second arrangement can appear alternately. For example, as Figure 6As shown, the sub-pixel areas in the pixel area PR of the first unit E11 may have a first arrangement, while the sub-pixel areas in the pixel area PR of the first unit E12 adjacent to the first unit E11 in the first direction DR1 may have a second arrangement. Furthermore, multiple first units E1 arranged in the first display panel DP1 along a second direction DR2 (e.g., direction X, but not limited thereto) perpendicular to the first direction DR1 may have the same arrangement. For example, the first units E1 located in the same row as the first unit E11 in the second direction DR2 may all have the first arrangement, while the first units E1 located in the same row as the first unit E12 in the second direction DR2 may all have the second arrangement. In this embodiment, the first arrangement and the second arrangement may be rotationally symmetrical to each other. "The first arrangement and the second arrangement are rotationally symmetrical to each other" here may include any suitable embodiment where the color order of the multiple sub-pixel areas with the first arrangement along a direction is the same as the color order of the multiple sub-pixel areas with the second arrangement along that direction after rotating these sub-pixel areas at a specific angle. For example, in this embodiment, after rotating the multiple sub-pixel areas with the first arrangement in the first unit E11 by 180 degrees, the color order of these sub-pixel areas along the first direction DR1 can be changed to red, green, and blue, which is the same as the color order of the multiple sub-pixel areas along the first direction DR1 in the second arrangement. That is, in this embodiment, the first arrangement and the second arrangement can be rotated symmetrically with each other when the rotation angle is 180 degrees. In other words, in this embodiment, the color order of the multiple sub-pixel areas along the first direction DR1 in the first arrangement can be the reverse of the color order of the multiple sub-pixel areas along the first direction DR1 in the second arrangement. At this time, the first arrangement and the second arrangement can be mirror-symmetrical with each other in the second direction DR2, and a surface parallel to the splicing edge TP can be used as a plane of symmetry. It should be noted that the rotation angle that makes the first arrangement and the second arrangement rotate symmetrical with each other can be determined according to the rotation angle of the display panel when the display panel is rotated and spliced ​​into a splicing display device TD. In addition, when the first arrangement and the second arrangement can be rotated symmetrical with each other, the first arrangement and the second arrangement can be any suitable arrangement, and are not limited to those described above. For structural details of the first unit E1 in this embodiment, please refer to [reference needed]. Figures 3 to 5 As mentioned above, the arrangement of sub-pixel areas in other display panels of the splicing display device TD (such as the second display panel DP2) can be the same as that of the first display panel DP1, so it will not be described again.

[0048] By arranging the sub-pixel areas as described above, and rotating and splicing the first display panel DP1 and the second display panel DP2 (for example, rotating the second display panel DP2 by 180 degrees, but not limited thereto) to form a splicing display device TD, the splicing display device TD may include a first display portion A1 and a first peripheral portion B1 of the first display panel DP1, and a second display portion A2 and a second peripheral portion B2 of the second display panel DP2. The first display portion A1 includes multiple first units E1, and the second display portion A2 includes multiple second units E2. The structure of the second unit E2 may be the same as that of the first unit E1, and its features can be referred to above, so they will not be repeated here. The splicing display device TD also includes a first driving circuit board DC1 disposed in the first peripheral portion B1 and a second driving circuit board DC2 disposed in the second peripheral portion B2. In addition, in the splicing display device TD, the multiple first units E1 may include a first repeating unit RU1, and the multiple second units E2 may include a second repeating unit RU2. The sub-pixel areas in the first repeating unit RU1 have the first arrangement described above, and the sub-pixel areas in the second repeating unit RU2 have the second arrangement described above. In other words, the first unit E1 and / or the second unit E2 with a first arrangement of subpixel areas can be regarded as the first repeating unit RU1, and the first unit E1 and / or the second unit E2 with a second arrangement of subpixel areas can be regarded as the second repeating unit RU2. Specifically, the first display portion A1 of the first display panel DP1 includes a plurality of first repeating units RU1 and second repeating units RU2, or the first display portion A1 is composed of a plurality of first repeating units RU1 and a plurality of second repeating units RU2, wherein one of the first repeating units RU1 (e.g., the first unit E11) is adjacent to a second repeating unit RU2 (e.g., the first unit E12) in the first direction DR1. Similarly, the second display portion A2 of the second display panel DP2 includes a plurality of first repeating units RU1 and a plurality of second repeating units RU2, or the second display portion A2 is composed of a plurality of first repeating units RU1 and a plurality of second repeating units RU2, wherein one of the first repeating units RU1 (e.g., the second unit E21) is adjacent to a second repeating unit RU2 (e.g., the second unit E22) in the first direction DR1. In this embodiment, the first repeating unit RU1 and the second repeating unit RU2 can be located on both sides of the splicing edge TP of the splicing display device TD, and the first repeating unit RU1 and the second repeating unit RU2 form at least a part of a repeating unit combination RB. For example, as Figure 6As shown, a first repeating unit RU1 (e.g., first unit E11) and a second repeating unit RU2 (e.g., second unit E22) located on both sides of the splicing edge TP of the splicing display device TD can form a repeating unit combination RB. The repeating unit combination RB can span the splicing edge TP, or in other words, the repeating unit combination RB can extend from the first display panel DP1 to the second display panel DP2. According to this embodiment, the repeating unit combination RB can repeatedly appear in the first display portion A1 and the second display portion A2. Specifically, the first display portion A1 and the second display portion A2 each include a plurality of repeating unit combinations RB ( Figure 6 (Example: Only one repeating unit combination RB is marked in the first display portion A1 and the second display portion A2). In some embodiments, the first display portion A1 and the second display portion A2 may each be composed of multiple repeating unit combinations RB. For example, these repeating unit combinations RB may be arranged in a matrix along the first direction DR1 and the second direction DR2 to form the first display portion A1 and the second display portion A2. In other words, through the above-described sub-pixel area arrangement design, the arrangement of the sub-pixel areas near the splicing edge TP can be the same as the arrangement of the sub-pixel areas in other areas (e.g., within each display panel). In this way, the possibility of light source unevenness (mura) at the splicing edge TP can be reduced, thereby improving the display quality of the splicing display device TD. It should be noted that the structural details of the first unit E1 and the second unit E2 in this embodiment can refer to the structure of the first unit E1 in the above embodiment, so they will not be repeated. The structure of the first repeating unit RU1 (or the second repeating unit RU2) is the same as the structure of the first unit E1 (or the second unit E2), so it can also be referred to Figures 3 to 5 And related content above.

[0049] Please refer to Figure 7 , Figure 7 This is a top view schematic diagram of the splicing display device according to the third embodiment of the present invention. The display panel of the splicing display device TD in this embodiment is... Figure 6 One of the main differences in the display panel of the TD splicing display device shown is the arrangement design of the sub-pixel areas. Compared to Figure 6 In the embodiment shown, in the first display panel DP1 of this embodiment, the first arrangement and the second arrangement can alternately appear in the plurality of first units E1 arranged along the second direction DR2. Details of the first arrangement and the second arrangement can be found above, and will not be repeated here. For example, as... Figure 7As shown, the sub-pixel areas in the pixel area PR of the first unit E11 can have a first arrangement, while the sub-pixel areas in the pixel area PR of the first unit E12 adjacent to the first unit E11 in the second direction DR2 can have a second arrangement. Furthermore, the multiple first units E1 arranged along the first direction DR1 in the first display panel DP1 can have the same arrangement. For example, the first units E1 located in the same row as the first unit E11 in the first direction DR1 can all have the first arrangement, while the first units E1 located in the same row as the first unit E12 in the first direction DR1 can all have the second arrangement. The arrangement design of the sub-pixel areas in other display panels of the splicing display device TD (e.g., the second display panel DP2) can be the same as that of the first display panel DP1, and therefore will not be described further.

[0050] Through the above-described sub-pixel arrangement design, after rotating and splicing the first display panel DP1 and the second display panel DP2 (for example, rotating the second display panel DP2 by 180 degrees, but not limited thereto) into a splicing display device TD, the plurality of first units E1 may include a first repeating unit RU1, and the plurality of second units E2 may include a second repeating unit RU2. The definition of the first repeating unit RU1 and the second repeating unit RU2 can be referred to above. Specifically, the first display portion A1 of the first display panel DP1 includes a plurality of first repeating units RU1 and second repeating units RU2, or in other words, the first display portion A1 is composed of a plurality of first repeating units RU1 and a plurality of second repeating units RU2, wherein one of the first repeating units RU1 (e.g., first unit E11) is adjacent to a second repeating unit RU2 (e.g., first unit E12) in the second direction DR2. Similarly, the second display portion A2 of the second display panel DP2 includes a plurality of first repeating units RU1 and a plurality of second repeating units RU2, or in other words, the second display portion A2 is composed of a plurality of first repeating units RU1 and a plurality of second repeating units RU2, wherein one of the first repeating units RU1 (e.g., second unit E21) is adjacent to a second repeating unit RU2 (e.g., second unit E22) in the second direction DR2. The first repeating units RU1 and the second repeating units RU2 may be located on opposite sides of the splicing edge TP of the splicing display device TD, and the first repeating units RU1 and the second repeating units RU2 form at least a part of a repeating unit combination RB. In detail, as shown below... Figure 7As shown, the repeating unit combination RB in this embodiment can be composed of two first repeating units RU1 and two second repeating units RU2. Specifically, the repeating unit combination RB can include two first repeating units RU1 and two second repeating units RU2 arranged in a 2*2 matrix. For example, first unit E11, first unit E12, second unit E21, and second unit E22 can form a repeating unit combination RB. In this case, one first repeating unit RU1 (e.g., first unit E11) and one second repeating unit RU2 (e.g., second unit E22) can be located on both sides of the splicing edge TP and are part of the repeating unit combination RB. The repeating unit combination RB can span the splicing edge TP, or in other words, the repeating unit combination RB can extend from the first display panel DP1 to the second display panel DP2. According to this embodiment, as Figure 7 As shown, the first display portion A1 and the second display portion A2 each include a plurality of repeating unit combinations RB (only one repeating unit combination RB is indicated for each of the first display portion A1 and the second display portion A2). In some embodiments, the first display portion A1 and the second display portion A2 may each be composed of a plurality of repeating unit combinations RB. For example, these repeating unit combinations RB may be arranged in a matrix along the first direction DR1 and the second direction DR2 to form the first display portion A1 and the second display portion A2.

[0051] Please refer to Figure 8 , Figure 8 This is a top view schematic diagram of the splicing display device according to the fourth embodiment of the present invention. The display panel of the splicing display device TD in this embodiment is... Figure 6 One of the main differences in the display panels of the splicing display device TD shown is the arrangement design of the sub-pixel areas. In this embodiment, the sub-pixel areas of the first unit E1 of the first display panel DP1 can be arranged along the second direction DR2 (e.g., direction X, but not limited thereto). Furthermore, the sub-pixel areas in the pixel area PR of the first unit E1 can each have a first arrangement or a second arrangement. For example, as... Figure 8 As shown, the first unit E11 in the first display panel DP1 may have a first arrangement, while the first unit E12 may have a second arrangement. In this embodiment, the first arrangement refers, for example, to the arrangement of three sub-pixel areas along the second direction DR2 (i.e., from left to right) in the order of blue sub-pixel area, green sub-pixel area, and red sub-pixel area, while the second arrangement refers, for example, to the arrangement of three sub-pixel areas along the second direction DR2 (i.e., from left to right) in the order of red sub-pixel area, green sub-pixel area, and blue sub-pixel area. The first and second arrangements can be rotationally symmetrical with each other; for example, the first and second arrangements can be rotationally symmetrical with each other when the rotation angle is 180 degrees. Furthermore, in this embodiment, the first and second arrangements can be mirror-symmetrical with each other along the first direction DR1.

[0052] According to this embodiment, among the plurality of first units E1 arranged along the second direction DR2 in the first display panel DP1, the first arrangement and the second arrangement can alternate. For example, as Figure 8 As shown, the sub-pixel areas in the pixel area PR of the first unit E11 can have a first arrangement, while the sub-pixel areas in the pixel area PR of the first unit E12 adjacent to the first unit E11 in the second direction DR2 can have a second arrangement. Furthermore, according to this embodiment, in the first display panel DP1, a first arrangement order and a second arrangement order can be defined among the arrangement methods of the plurality of first units E1 arranged along the first direction DR1 (i.e., the aforementioned first and second arrangement methods). Specifically, the first arrangement order can refer to the arrangement of the sub-pixel areas in two adjacent first units E1 arranged along the first direction DR1 being sequentially the first arrangement method and the second arrangement method, while the second arrangement order can refer to the arrangement of the sub-pixel areas in two adjacent first units E1 arranged along the first direction DR1 being sequentially the second arrangement method and the first arrangement method. For example, the sub-pixel areas in the first unit E13 and the first unit E11 arranged along the first direction DR1 can sequentially have the second arrangement method and the first arrangement method, in which case the arrangement of the sub-pixel areas in the first unit E13 and the first unit E11 can be defined as having a second arrangement order. Furthermore, the sub-pixel areas in the first units E15 and E14 arranged along the first direction DR1 can sequentially have a first arrangement and a second arrangement. In this case, the arrangement of the sub-pixel areas in the first units E15 and E14 can be defined as having a first arrangement order. According to this embodiment, the arrangement of the plurality of first units E1 arranged along the first direction DR1 can alternately have a first arrangement order and a second arrangement order. For example, such as... Figure 8 As shown, the sub-pixel areas of the four first units E1 located in the leftmost row of the first display panel DP1, arranged along the first direction DR1 (from bottom to top), can be arranged in a second arrangement order and a first arrangement order, respectively. It should be noted that... Figure 8The number of first units E1 in the first display panel DP1 is merely exemplary and is not limited to this embodiment. In some embodiments, the first display panel DP1 may include more first units E1, and the sub-pixel areas of the first units E1 may be arranged alternately in a second arrangement order and a first arrangement order, or alternately in a first arrangement order and a second arrangement order, along the first direction DR1. In short, in this embodiment, the sub-pixel areas in a plurality of first units E1 arranged along the second direction DR2 may be arranged alternately in a first arrangement order and a second arrangement order, while the sub-pixel areas in a plurality of first units E1 arranged along the first direction DR1 may alternately have a first arrangement order and a second arrangement order. In some embodiments, the sub-pixel areas in a plurality of first units E1 arranged along the first direction DR1 may alternately have a first arrangement order and a second arrangement order, while the sub-pixel areas in a plurality of first units E1 arranged along the second direction DR2 may alternately have a first arrangement order and a second arrangement order. The arrangement design of the sub-pixel areas in other display panels of the splicing display device TD (e.g., the second display panel DP2) may be the same as that of the first display panel DP1, and therefore will not be described in detail.

[0053] By arranging the sub-pixel areas as described above, after rotating and splicing the first display panel DP1 and the second display panel DP2 (for example, rotating the second display panel DP2 by 180 degrees, but not limited thereto) into a splicing display device TD, the plurality of first units E1 may include a first repeating unit RU1, and the plurality of second units E2 may include a second repeating unit RU2. The sub-pixel areas in the first repeating unit RU1 have the first arrangement described above, and the sub-pixel areas in the second repeating unit RU2 have the second arrangement described above. Specifically, the first display portion A1 of the first display panel DP1 includes a plurality of first repeating units RU1 and a plurality of second repeating units RU2, or in other words, the first display portion A1 is composed of a plurality of first repeating units RU1 and a plurality of second repeating units RU2. Similarly, the second display portion A2 of the second display panel DP2 includes a plurality of first repeating units RU1 and a plurality of second repeating units RU2, or in other words, the second display portion A2 is composed of a plurality of first repeating units RU1 and a plurality of second repeating units RU2. In the first display panel DP1 and the second display panel DP2, a first repeating unit RU1 may be adjacent to multiple second repeating units RU2 in the first direction DR1 and the second direction DR2. The first repeating unit RU1 and the second repeating units RU2 may be located on both sides of the splicing edge TP of the splicing display device TD, and the first repeating unit RU1 and the second repeating unit RU2 form at least a part of a repeating unit combination RB. In detail, as follows... Figure 8As shown, the repeating unit combination RB in this embodiment can be composed of two first repeating units RU1 and two second repeating units RU2. Specifically, the repeating unit combination RB can include two first repeating units RU1 and two second repeating units RU2 arranged in a 2*2 matrix. For example, first unit E11, first unit E12, second unit E21 and second unit E22 can form a repeating unit combination RB. In this case, one first repeating unit RU1 (e.g., first unit E11) and one second repeating unit RU2 (e.g., second unit E22) can be located on both sides of the splicing edge TP and are part of the repeating unit combination RB. The repeating unit combination RB can span the splicing edge TP, or in other words, the repeating unit combination RB can extend from the first display panel DP1 to the second display panel DP2. In addition, two first repeating units RU1 (or two second repeating units RU2) can be located on both sides of the splicing edge TP and correspond to each other. In this embodiment, the first display portion A1 and the second display portion A2 each include multiple repeating unit combination RBs (only one repeating unit combination RB is marked in each of the first display portion A1 and the second display portion A2 as an example). In some embodiments, the first display portion A1 and the second display portion A2 may each be composed of a plurality of repeating unit combinations RB. For example, these repeating unit combinations RB may be arranged in a matrix to form the first display portion A1 and the second display portion A2.

[0054] Please refer to Figure 9 , Figure 9 This is a top view schematic diagram of a splicing display device according to a fifth embodiment of the present invention. According to this embodiment, the pixel area PR of the first unit E1 of the first display portion A1 of the display panel (e.g., the first display panel DP1) in the splicing display device TD may include three sub-pixel areas, namely sub-pixel area SPR1, sub-pixel area SPR2, and sub-pixel area SPR3. Sub-pixel areas SPR1, SPR2, and SPR3 may be sub-pixel areas of three colors, for example, red, green, and blue sub-pixel areas respectively, but are not limited thereto. In some embodiments, the pixel area PR may include more than three sub-pixel areas. According to this embodiment, in the first display panel DP1, the sub-pixel areas in the four first units E1 arranged in a 2*2 matrix may respectively have a first arrangement, a second arrangement, a third arrangement, and a fourth arrangement. For example, as... Figure 9As shown, the arrangement of sub-pixel regions in the first unit E11 can be defined as the first arrangement, the arrangement of sub-pixel regions in the first unit E12 can be defined as the second arrangement, the arrangement of sub-pixel regions in the first unit E13 can be defined as the third arrangement, and the arrangement of sub-pixel regions in the first unit E14 can be defined as the fourth arrangement. The first arrangement may refer to that the sub-pixel regions SPR1,SPR2, and SPR3 are arranged in a "pin" shape, where the sub-pixel region SPR1 may be located at the top position of the "pin" shape, and the sub-pixel regions SPR2 and SPR3 may be located at the bottom positions of the "pin" shape, but not limited thereto. In some embodiments, the top position of the "pin" shape may correspond to the sub-pixel region SPR2 or the sub-pixel region SPR3. The second arrangement can be obtained by rotating the first arrangement clockwise by 90 degrees, the third arrangement can be obtained by rotating the first arrangement clockwise by 180 degrees, and the fourth arrangement can be obtained by rotating the first arrangement clockwise by 270 degrees. In this case, the first arrangement, the second arrangement, the third arrangement, and the fourth arrangement may be rotationally symmetric to each other. For example, the first arrangement is rotationally symmetric to the second arrangement, the third arrangement, and the fourth arrangement at rotation angles of 90 degrees, 180 degrees, and 270 degrees respectively. The above arrangements of sub-pixel regions may repeatedly appear in the first display panel DP1. In other words, for any four first units E1 arranged in a 2*2 matrix in the first display panel DP1, the sub-pixel regions in these four first units E1 may respectively have the first arrangement, the second arrangement, the third arrangement, and the fourth arrangement. It should be noted that although Figure 9 the sub-pixel regions SPR1, SPR2, and SPR3 may be connected to each other, this embodiment is not limited thereto. In some embodiments, the sub-pixel regions SPR1, SPR2, and SPR3 may be separated from each other. The arrangement design of sub-pixel regions in other display panels of the tiled display device TD (such as the second display panel DP2, the third display panel DP3, and the fourth display panel DP4) may be the same as that of the first display panel DP1, so details are not described herein again.

[0055] In this embodiment, the splicing display panel TD can be formed, for example, by splicing together a first display panel DP1, a second display panel DP2, a third display panel DP3, and a fourth display panel DP4. The third display panel DP3 may include a third display portion A3 and a third peripheral portion B3. The third display portion A3 includes multiple third units E3, and the third peripheral portion B3 includes a third driving circuit board DC3. The fourth display panel DP4 may include a fourth display portion A4 and a fourth peripheral portion B4. The fourth display portion A4 includes multiple fourth units E4, and the fourth peripheral portion B4 includes a fourth driving circuit board DC4. The structures of the third display panel DP3 and the fourth display panel DP4 can be the same as those of the first display panel DP1; their structural details can be found in [reference needed]. Figures 3 to 5 And the relevant content above. Specifically, in this embodiment, the first display panel DP1, the second display panel DP2, the third display panel DP3, and the fourth display panel DP4 can be spliced ​​together to form a splicing display device TD by rotation splicing, so that the display parts of each display panel can be spliced ​​along their sides that are not adjacent to the surrounding parts. For example, as Figure 9 As shown, the structure of the second display panel DP2 can be obtained by rotating the structure of the first display panel DP1 90 degrees clockwise. This can be considered as rotating one first display panel DP1 90 degrees clockwise and then splicing it with another first display panel DP1. Similarly, the structure of the third display panel DP3 can be obtained by rotating the structure of the first display panel DP1 180 degrees. Furthermore, the arrangement design of the sub-pixel areas in some display panels (e.g., the fourth display panel DP4) in the splicing display device TD is the same as that of the first display panel DP1, but its structure (e.g., the size and placement of the peripheral parts) can differ from that of the first display panel DP1, but this is not a limitation. It should be noted that... Figure 9 The splicing method of the splicing display device TD shown can be applied to the above embodiments and variations.

[0056] Through the above-described sub-pixel area arrangement design, in the splicing display device TD, the plurality of first units E1 of the first display panel DP1 may include a first repeating unit RU1, wherein the sub-pixel areas in the first repeating unit RU1 (e.g., first unit E11) have the above-described first arrangement; and the plurality of second units E2 may include a second repeating unit RU2, wherein the sub-pixel areas in the second repeating unit RU2 (e.g., second unit E22) have the above-described third arrangement. The first display portion A1 of the first display panel DP1, the second display portion A2 of the second display panel DP2, the third display portion A3 of the third display panel DP3, and the fourth display portion A4 of the fourth display panel DP4 each include a plurality of first repeating units RU1 and second repeating units RU2. The first repeating unit RU1 and the second repeating unit RU2 may be located on both sides of one of the splicing edges TP of the splicing display device TD, and the first repeating unit RU1 and the second repeating unit RU2 form at least a part of a repeating unit combination RB. In detail, as Figure 9 As shown, the repeating unit combination RB in this embodiment can, for example, be composed of first units E11, E12, E21, and E22 arranged in a 2*2 matrix, and includes first repeating units RU1 (i.e., first unit E11) and second repeating units RU2 (i.e., second unit E22) located on both sides of the splicing edge TP (the splicing edge between the first display panel DP1 and the second display panel DP2). The repeating unit combination RB can span the splicing edge TP, or in other words, the repeating unit combination RB can extend from the first display panel DP1 to the second display panel DP2. The sub-pixel areas in the four units (including two first units E1 and two second units E2) of the repeating combination unit RB have the aforementioned first arrangement, second arrangement, third arrangement, and fourth arrangement, respectively. According to this embodiment, as Figure 9 As shown, the first display portion A1, the second display portion A2, the third display portion A3, and the fourth display portion A4 each include multiple repeating unit combinations RB (only one repeating unit combination RB is shown in each display portion as an example). In some embodiments, the first display portion A1, the second display portion A2, the third display portion A3, and the fourth display portion A4 may each be composed of multiple repeating unit combinations RB. For example, these repeating unit combinations RB can be arranged in a matrix to form the first display portion A1, the second display portion A2, the third display portion A3, and the fourth display portion A4. Through the sub-pixel area arrangement design of this embodiment, the arrangement of the sub-pixel areas near the splicing edge TP can be the same as the arrangement of the sub-pixel areas in other areas (e.g., within each display panel). In this way, the possibility of light source unevenness (mura) at the splicing edge TP can be reduced, thereby improving the display quality of the splicing display device TD.

[0057] Please refer to Figure 10 , Figure 10 This is a top view schematic diagram of a splicing display device according to a sixth embodiment of the present invention. In this embodiment, the pixel area PR of the first unit E1 of the first display panel DP1 of the splicing display device TD may include three sub-pixel areas, namely sub-pixel area SPR1, sub-pixel area SPR2, and sub-pixel area SPR3. Sub-pixel areas SPR1, SPR2, and SPR3 may be sub-pixel areas of three colors, for example, red sub-pixel area, green sub-pixel area, and blue sub-pixel area, respectively, but are not limited thereto. In some embodiments, pixel area PR may include more than three sub-pixel areas. According to this embodiment, in the top view direction of the first display panel DP1, the pattern of the three sub-pixel areas in a pixel area PR can have rotational symmetry with the same point as the center. For example, as Figure 10 As shown, in the top view of the first display panel DP1, the pattern of sub-pixel area SPR3 can be windmill-shaped or dart-shaped, wherein the shape of sub-pixel area SPR3 is rotationally symmetrical with point PO1 as the center. Sub-pixel area SPR2 can be arranged around sub-pixel area SPR3. Specifically, sub-pixel areas SPR3 and SPR2 can be arranged in a rectangular (e.g., square) area, wherein the shape of the rectangular area is rotationally symmetrical with point PO1 as the center. Sub-pixel area SPR2 is arranged in other areas of this rectangular area besides sub-pixel area SPR3. In this case, the pattern of sub-pixel area SPR2 can also be rotationally symmetrical with point PO1 as the center. Sub-pixel area SPR1 can be arranged around sub-pixel areas SPR3 and SPR2, and the shape of the outer edge of sub-pixel area SPR1 can be a regular polygon (e.g., a regular octagon), wherein the pattern of sub-pixel area SPR1 is rotationally symmetrical with point PO1 as the center. In other words, the shapes of sub-pixel region SPR1, SPR2, and the pattern of sub-pixel region SPR3 all exhibit rotational symmetry around point PO1. It should be noted that, although... Figure 10 Sub-pixel regions SPR1, SPR2, and SPR3 may be connected to each other, but this embodiment is not limited thereto. In some embodiments, sub-pixel regions SPR1, SPR2, and SPR3 may be separated from each other. In this case, a region that is not a sub-pixel region may exist between sub-pixel regions SPR1 and SPR2, and between sub-pixel regions SPR2 and SPR3. Furthermore, Figure 10The arrangement and pattern of the sub-pixel areas shown are merely exemplary and are not intended to limit the invention. In other embodiments, sub-pixel areas SPR1, SPR2, and SPR3 may each include other suitable patterns, such that the patterns of sub-pixel areas SPR1, SPR2, and SPR3 can be rotationally symmetrical around the same point (e.g., point PO1). The pattern design of the sub-pixel areas in other display panels of the splicing display device TD (e.g., the second display panel DP2 and the third display panel DP3) can be the same as that of the first display panel DP1, and therefore will not be described further.

[0058] In this embodiment, the splicing display device TD can be formed by rotating and splicing a first display panel DP1, a second display panel DP2, and a third display panel DP3. For example, the structure of the second display panel DP2 can be obtained by rotating the structure of the first display panel DP1 90 degrees clockwise, which can be regarded as splicing a first display panel DP1 with another first display panel DP1 after rotating it 90 degrees clockwise. Similarly, the structure of the third display panel DP3 can be obtained by rotating the structure of the first display panel DP1 90 degrees counterclockwise. In addition, in this embodiment, one side of a display panel can be used to splice with multiple display panels. For example, as Figure 10 As shown, the side SL2 of the first display panel DP1 can be used simultaneously for splicing with the second display panel DP2 and the third display panel DP3, but is not limited thereto. The splicing method of the display panels in this embodiment can be applied to the above embodiments and variations.

[0059] By using the aforementioned sub-pixel pattern design, after rotating and splicing the first display panel DP1, the second display panel DP2, and the third display panel DP3 into a video wall display device TD, the sub-pixel area shapes can possess rotational symmetry. Therefore, the pattern of the sub-pixel area near the splicing edge TP can be approximately the same as the pattern of the sub-pixel area in other areas (e.g., within each display panel). This reduces the possibility of uneven light source distribution (mura) at the splicing edge TP, thereby improving the display quality of the video wall display device TD.

[0060] In summary, the present invention provides a display panel and a splicing display device formed using the display panel, wherein the arrangement or pattern design of the sub-pixel areas of the display panel can be designed, for example, to make the arrangement or pattern of the sub-pixel areas rotationally symmetrical, thereby reducing the possibility that users may observe uneven light source (mura) at the splicing edge of the splicing display device, thereby improving the display quality of the splicing display device.

[0061] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
