Any device with equivalent functionality resulting from the reconfiguration of the components is within the scope of the present invention. Furthermore, the drawings are for illustrative purposes only and are not drawn to scale.

[0051] The terms “first,” “second,” etc. used in this document do not particularly refer to an order or sequence, but are only used to distinguish elements or operations described with the same technical terms.

[0052] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a transparent display 100 according to an embodiment of the present invention is shown. The transparent display 100 includes a plurality of first transparent sub-displays 110 and a plurality of second transparent sub-displays 120. The first transparent sub-displays 110 and the second transparent sub-displays 120 are spliced ​​together to form a larger transparent display 100. The first transparent sub-displays 110 are spliced ​​together along a first direction D1 (i.e., the x-axis direction), the second transparent sub-displays 120 are spliced ​​together along the first direction D1, and the first transparent sub-displays 110 and the corresponding second transparent sub-displays 120 are spliced ​​together along a second direction D2 (i.e., the y-axis direction), thereby forming the transparent display 100. However, the embodiments of the present invention are not limited to this. In this embodiment, the transparent display 100 includes two rows of spliced ​​transparent sub-displays. However, in other embodiments of the present invention, the transparent display 100 may include only one row of spliced ​​transparent sub-displays, or may include more rows of spliced ​​transparent sub-displays.

[0053] The first transparent sub-display 110 includes a first display panel 111 and a plurality of first driving circuit chips 112. The first driving circuit chip 112 is arranged along the first direction D1 to be electrically connected to the first display panel 111 to drive the corresponding first display panel 111. In the present embodiment, the first driving circuit chip 112 is a chip on film (COF), but the embodiments of the present invention are not limited thereto. Similarly, the second transparent sub-display 120 includes a second display panel 121 and a plurality of second driving circuit chips 122. The second driving circuit chip 122 is arranged along the first direction D1 to be electrically connected to the second display panel 121 to drive the corresponding second display panel 121. In the present embodiment, the second driving circuit chip 122 is also a chip on film package, but the embodiments of the present invention are not limited thereto.

[0054] For convenience of representation, the x-axis direction is expressed in degrees. To express, and the y-axis direction, in degrees For example, the angle between the first direction D1 and the x-axis is is 0 degrees. Moreover, the angle between the second direction D2 and the x-axis is is 90 degrees.

[0055] Please refer to Figure 2 , which illustrates a schematic diagram of a pixel structure of the first display panel 111 according to an embodiment of the present invention. The first display panel 111 includes a plurality of pixel structures, and utilizes these pixel structures to display image data. The above-mentioned pixel structure includes a black matrix and a plurality of light-emitting elements. In this embodiment, as Figure 2 In the figure, only the first black matrix 210, the second black matrix 220, the third black matrix 230, the fourth black matrix 240 and the high-brightness light-emitting element GL among the light-emitting elements are shown. In an embodiment of the present invention, the light-emitting elements are red, blue and green light-emitting diodes, and the high-brightness light-emitting element GL is a green light-emitting diode.

[0056] The light-emitting elements of this embodiment, such as the high-brightness light-emitting element GL, are disposed in the bonding area RA. A first black matrix 210, a second black matrix 220, a third black matrix 230, and a fourth black matrix 240 surround the bonding area RA to shield the circuit traces on the first display panel 111 and provide a color separation effect.

[0057] The first black matrix 210 and the second black matrix 220 are located on the left and right sides of the bonding area RA and are opposite to each other. The first black matrix 210 and the second black matrix 220 extend along the second direction D2. In this embodiment, the second black matrix 220 corresponds to shielding the data lines of the first display panel 111. The third black matrix 230 and the fourth black matrix 240 are located on the upper and lower sides of the bonding area RA and are opposite to each other. The third black matrix 230 and the fourth black matrix 240 are located between the first black matrix 210 and the second black matrix 220 and extend along the first direction D1. In this embodiment, the second black matrix 220 corresponds to shielding the scan lines of the first display panel 111.

[0058] There is a first distance L1 between the high-brightness light-emitting element GL and the first black matrix 210. There is a second distance L2 between the high-brightness light-emitting element GL and the second black matrix 220. There is a third distance L3 between the high-brightness light-emitting element GL and the third black matrix 230. There is a fourth distance L4 between the high-brightness light-emitting element GL and the fourth black matrix 240. In this embodiment, in order to reduce back light leakage, this embodiment designs the above-mentioned first distance L1, second distance L2, third distance L3, and fourth distance L4 as follows: the sum of the first distance L1 and the second distance L2 is greater than the sum of the third distance L3 and the fourth distance L4; the values ​​of the third distance L3 and the fourth distance L4 are greater than or equal to 40 microns (um); the minimum of the first distance L1, the second distance L2, the third distance L3, and the fourth distance L4 is located at Upward, that is, extending along the second direction D2.

[0059] Through the above design, the light leakage from the back of the transparent display 100 according to the embodiment of the present invention can be reduced by, for example, approximately 4 times.

[0060] Please refer to Figure 3 In some embodiments, considering that the high-brightness light-emitting element GL may not be set in the expected main setting position (shown in a dotted box), but can only be moved upward and set in a spare maintenance position, in this case, there is a third distance L31 between the high-brightness light-emitting element GL and the third black matrix 230, and a fourth distance L41 between the high-brightness light-emitting element GL and the fourth black matrix 240. Taking into account the position change of the high-brightness light-emitting element GL, the above distances are designed as follows: the minimum of the third distance L3 / L31 and the fourth distance L4 / L41 is located at In this way, the light leakage phenomenon at the rear side of the transparent display 100 can be improved.

[0061] Please refer to Figure 4 In some embodiments, circuit traces on the transparent display 100, such as data lines, are arranged as closely together as possible, taking into account their potential impact on light diffraction. For example, these traces have a relatively small width LA. Furthermore, in this embodiment, the traces with the largest width (in this embodiment, the data lines) extend perpendicular to the first direction D1, i.e., the direction in which the COFs are arranged.

[0062] Furthermore, considering that the connecting area RA is rectangular, the longest side of the rectangular connecting area RA is designed to be parallel to the first direction D1 to further improve the rear light leakage phenomenon of the transparent display 100 .

[0063] Please refer to Figure 5, which illustrates a schematic diagram of splicing the first display panel 111 of the first transparent sub-display 110 and the second display panel 121 of the second transparent sub-display 120 according to another embodiment of the present invention. Figure 5 The first display panel 111 includes a plurality of pixel structures 510, each of which includes a plurality of first light-emitting elements 511, 512, and 513. Similarly, the second display panel 121 includes a plurality of pixel structures 520, each of which includes a plurality of second light-emitting elements 521, 522, and 523. In this embodiment, the first light-emitting elements 511, 512, and 513 include red, blue, and green LEDs, and the second light-emitting elements 521, 522, and 523 also include red, blue, and green LEDs, but the present invention is not limited thereto.

[0064] The pixel structure 510 of the first display panel 111 and the pixel structure 520 of the second display panel 121 are spliced ​​together at a splicing line, defining a splicing portion 530. In this embodiment, the splicing portion 530 includes the first light-emitting element 513 and the second light-emitting element 523 adjacent to each other in the pixel structure 510 and the pixel structure 520. In other words, the first light-emitting element 513 is the light-emitting element closest to the pixel structure 520 in the pixel structure 510, and the second light-emitting element 523 is the light-emitting element closest to the pixel structure 510 in the pixel structure 520. In this embodiment, if the first light-emitting element 513 and the second light-emitting element 523 are light-emitting elements of the same color, such as blue light-emitting elements, a noticeable blue line will appear at the splicing portion 530. Therefore, in this embodiment, the first light-emitting element 513 and the second light-emitting element 523 are designed to be light-emitting elements of different colors to avoid noticeable color stripes at the splicing portion 530.

[0065] Please refer to Figure 6 , which is a schematic diagram illustrating the splicing of the first display panel 111 of the first transparent sub-display and the second display panel 121 of the second transparent sub-display according to another embodiment of the present invention. Figure 6 The embodiment is similar to Figure 5 The embodiment of Figure 6In this embodiment, first light-emitting elements 511, 512, 513 and second light-emitting elements 521, 522, 523 are arranged horizontally. Thus, the joint 530 includes adjacent first light-emitting elements 511 and second light-emitting elements 521, adjacent first light-emitting elements 512 and second light-emitting elements 522, and adjacent second light-emitting elements 513 and second light-emitting elements 523 in the pixel structure 510 and the pixel structure 520. Because the light-emitting elements of this embodiment are arranged horizontally and have different colors (e.g., red, blue, and green), the appearance of obvious color stripes at the joint 530 can be avoided.

[0066] Please refer to Figure 7 , which shows a schematic diagram of two pixel structures 710 and 720 spliced ​​together according to another embodiment of the present invention, wherein the pixel structure 710 is located in the first display panel 111, and the pixel structure 720 is located in the second display panel 121. The pixel structure 710 includes a black matrix and a plurality of light-emitting elements. In this embodiment, as Figure 7 As shown, the pixel structure 710 includes a first black matrix 711, a second black matrix 712, a third black matrix 713, a fourth black matrix 714 and a first high-brightness light-emitting element GL1. Similarly, the pixel structure 720 also includes a black matrix and a plurality of light-emitting elements, such as Figure 7 As shown, the pixel structure 720 includes a fifth black matrix 721, a sixth black matrix 722, a seventh black matrix 723, an eighth black matrix 724 and a second high-brightness light-emitting element GL2. In this embodiment, the light-emitting elements in the pixel structures 710 and 720, such as red, blue and green light-emitting diodes, are arranged in a The plurality of layers extend upward, that is, are arranged along the second direction D2.

[0067] The first black matrix 711 and the second black matrix 712 are located on the left and right sides of the first high-brightness light-emitting element GL1 and are opposite to each other. The first black matrix 711 and the second black matrix 712 extend along the second direction D2. In this embodiment, the first black matrix 711 corresponds to shielding the data lines of the first display panel 111. The third black matrix 713 and the fourth black matrix 714 are located on the upper and lower sides of the first high-brightness light-emitting element GL1 and are opposite to each other.

In this embodiment, the fourth black matrix 714 corresponds to shielding the scan lines of the first display panel 111.

[0068] The fifth black matrix 721 and the sixth black matrix 722 are located on the left and right sides of the second high-brightness light-emitting element GL2 and are opposite to each other. The fifth black matrix 711 and the sixth black matrix 722 extend along the second direction D2. In this embodiment, the sixth black matrix 722 corresponds to shielding the data lines of the second display panel 121. The seventh black matrix 723 and the eighth black matrix 724 are located on the upper and lower sides of the second high-brightness light-emitting element GL2 and are opposite to each other. The seventh black matrix 723 and the eighth black matrix 724 extend along the first direction D1. In this embodiment, the seventh black matrix 723 corresponds to shielding the scan lines of the second display panel 121.

[0069] There is a first distance L11 between the first high-brightness light-emitting element GL1 and the first black matrix 711. There is a second distance L12 between the first high-brightness light-emitting element GL1 and the second black matrix 712. There is a third distance L13 between the first high-brightness light-emitting element GL1 and the third black matrix 713.

There is a fifth distance L21 between the second high-brightness light-emitting element GL2 and the fifth black matrix 721. There is a sixth distance L22 between the second high-brightness light-emitting element GL2 and the sixth black matrix 722. There is a seventh distance L23 between the second high-brightness light-emitting element GL2 and the seventh black matrix 723. There is an eighth distance L24 between the second high-brightness light-emitting element GL2 and the eighth black matrix 724. In this embodiment, in order to reduce back light leakage, the first distance L11, the second distance L12, the third distance L13, the fourth distance L14, the fifth distance L21, the sixth distance L22, the seventh distance L23 and the eighth distance L24 are designed as follows: the smallest of the first distance L11, the second distance L12, the third distance L13 and the fourth distance L14 is located at The smallest of the fifth distance L21, the sixth distance L22, the seventh distance L23 and the eighth distance L24 is located at In other words, in the two pixel structures 710 and 720, the smallest distance appears below the pixel structures 710 and 720.
