In some embodiments, the display layer 200 can be regarded as being disposed on the front side of the pixel array substrate 100 and the driving circuit 300 can be regarded as being disposed on the back side of the pixel array substrate 100, wherein the user is located on the front side to view the picture. The driving circuit 300 and the display layer 200 are stacked on each other in the thickness direction, but the display picture provided by the display layer 200 will not be blocked or affected by the driving circuit 300.
[0028] Figure 2 is a schematic diagram of the front side of a pixel array substrate according to an embodiment of the present invention, and Figure 3 FIG. 1 is a schematic diagram of the back side of a pixel array substrate according to an embodiment of the present invention. Figure 2 and Figure 3 The pixel array substrate 100 includes a substrate 110, a pixel circuit array 120, a plurality of first transmission pillars 130, a plurality of second transmission pillars 140, a plurality of first transmission lines 150, and a plurality of second transmission lines 160. The plurality of first transmission pillars 130 and the plurality of second transmission pillars 140 can each penetrate the substrate 110 and be electrically connected to the pixel circuit array 120. Figure 3, each of the plurality of first transmission lines 150 may be connected between one of the plurality of first transmission pillars 130 and the driving circuit 300, and each of the plurality of second transmission lines 160 may be connected between one of the plurality of second transmission pillars 140 and the driving circuit 300. In other words, the plurality of first transmission lines 150 and the plurality of second transmission lines 160 are all electrically connected to the driving circuit 300, and the plurality of first transmission pillars 130, the plurality of second transmission pillars 140, the plurality of first transmission lines 150 and the plurality of second transmission lines 160 are used to establish electrical transmission between the pixel circuit array 120 and the driving circuit 300. In some embodiments, the driving circuit 300, the plurality of first transmission lines 150 and the plurality of second transmission lines 160 may overlap the display area AA of the display device 10 (also overlap the display layer 200), and the peripheral area PA of the display device 10 may be very narrow. Here, the display area AA may be the display layer 200 (shown in FIG. 2 ). Figure 1 ), and the peripheral area PA can be an area from the edge of the display area AA to the edge of the substrate 110 (the first edge E1, the second edge E2, the third edge E3 and the fourth edge E4), but is not limited thereto.
[0029] The substrate 110 has a first surface 112 and a second surface 114 opposite to each other. Figure 2 The first surface 112 of the substrate 110 and the components disposed thereon are presented. Figure 3 The second surface 114 of the substrate 110 and the components disposed thereon are presented. The substrate 110 is a plate-shaped object with sufficient mechanical support. The substrate 110 is, for example, a glass plate, a plastic plate, etc. In some embodiments, the substrate 110 may be light-transmissive, but may also be a light-opaque plate.
[0030] The substrate 110 has a rectangular shape and includes a first edge E1, a second edge E2, a third edge E3 and a fourth edge E4. The first edge E1 and the second edge E2 are opposite to each other in a first direction D1, and the third edge E3 and the fourth edge E4 are opposite to each other in a second direction D2. In the present embodiment, the first direction D1 is substantially parallel to a direction from the first edge E1 of the substrate 110 to the second edge E2 of the substrate 110, and the second direction D2 is substantially parallel to a direction from the third edge E3 of the substrate 110 to the fourth edge E4 of the substrate 110.
[0031] The pixel circuit array 120 is disposed on the first surface 112 of the substrate 110. Figure 2, the pixel circuit array 120 may include a plurality of first signal lines 122, a plurality of second signal lines 124, a plurality of signal transmission lines 126, and a plurality of active devices 128. The plurality of first signal lines 122 each extend along a first direction D1 and are connected to one of the plurality of first transmission pillars 130. The plurality of second signal lines 124 each extend along a second direction D2 and are each connected to a corresponding one of the signal transmission lines 126. The plurality of signal transmission lines 126 each extend along the first direction D1 and are each connected to a corresponding one of the second transmission pillars 140. The plurality of active devices 128 each connect to a corresponding one of the plurality of first signal lines 122 and a corresponding one of the plurality of second signal lines 124. The first direction D1 and the second direction D2 may intersect with each other, for example, be orthogonal, but are not limited thereto.
[0032] In some embodiments, the plurality of first signal lines 122 transmit one of a scan signal and a data signal, and the plurality of second signal lines 124 transmit the other of the scan signal and the data signal. For example, the first signal line 122 is a scan line and the second signal line 124 is a data line, or the first signal line 122 is a data line and the second signal line 124 is a scan line. In some embodiments, the pixel circuit array 120 may further include a capacitor connected to each active element 128. In some embodiments, the pixel circuit array 120 may further include a touch element, a sensing element, an image acquisition element, a vibration element, or other elements for providing individual functions.
[0033] In this embodiment, the first signal line 122 extends along the first direction D1 to the corresponding first transmission pillar 130 and can be electrically connected to the first transmission line 150 located on the second surface 114 through the first transmission pillar 130. Therefore, the first signal line 122 does not need to extend beyond the first transmission pillar 130. The signal transmission line 126 extends along the first direction D1 to the corresponding second transmission pillar 140 and can be electrically connected to the second transmission line 160 located on the second surface 114 through the second transmission pillar 140. Therefore, the second signal line 124 does not need to extend beyond the second transmission pillar 140. Figure 2 As shown, the first transmission column 130 and the second transmission column 140 may be substantially located at the edge of the display area AA. In this way, the peripheral area PA between the display area AA and the first edge E1 of the substrate 110 and the peripheral area PA between the display area AA and the second edge E2 of the substrate 110 may be very narrow, which helps to achieve a narrow frame design in the first direction D1. In some embodiments, the width WD1 of the peripheral area PA between the display area AA and the first edge E1 (or the second edge E2) of the substrate 110 may be less than twice the lateral dimension W140 of each of the first transmission column 130 and the second transmission column 140.
[0034] In this embodiment, the second signal line 124 extends along the second direction D2 and is connected to a plurality of active components 128 arranged in the second direction D2. At the same time, each of the plurality of signal transmission lines 126 can be connected to one of the second signal lines 124 through a corresponding connection point CT. Each signal transmission line 126 can extend between one of the connection points CT and one of the second transmission pillars 140, but in some embodiments, the signal transmission line 126 can also selectively extend beyond the corresponding connection point CT. Figure 1 In the embodiment, two adjacent connection points CT are not on the same second signal line 124. The connection points CT are arranged along a diagonal path, but in other embodiments, they may be arranged along a V-shaped path or a zigzag path.
[0035] A second signal line 124 and a signal transmission line 126 connected by the connection point CT can provide a T-shaped or L-shaped signal transmission path. Therefore, the second signal line 124 does not need to extend beyond the display area AA in the second direction D2 and can provide a narrow peripheral area PA in the second direction D2, so that a narrow frame can also be implemented in the second direction D2. In some embodiments, the width WD2 of the peripheral area PA between the display area AA and the third edge E3 (or the fourth edge E4) of the substrate 110 in the second direction D2 can be smaller than the respective lateral dimensions W140 of the first transmission column 130 and the second transmission column 140.
[0036] In some embodiments, the pixel circuit array 120 may be composed of multiple conductive layers, multiple insulating layers, and at least one semiconductor layer. The first signal line 122 and the second signal line 124 may be composed of different conductive layers, and at least one insulating layer is disposed between the conductive layer of the first signal line 122 and the conductive layer of the second signal line 124. In this way, the first signal line 122 and the second signal line 124 may be interlaced with each other without contact. In some embodiments, the signal transmission line 126 and the second signal line 124 may be composed of different conductive layers, and at least one insulating layer is disposed between the conductive layer of the signal transmission line 126 and the conductive layer of the second signal line 124, and the connection point CT may penetrate the at least one insulating layer so that the signal transmission line 126 can be in electrical contact with the second signal line 124. In some embodiments, the conductive layer of the signal transmission line 126 and the conductive layer of the first signal line 122 may be selected to be the same conductive layer or different conductive layers.
[0037] Figure 4 FIG. 1 is a schematic diagram of the layout of the transmission line disposed on the back side of a display device according to an embodiment of the present invention. Figure 3 and Figure 4, each of the first transmission lines 150 has a first end 152 and a second end 154. The first ends 152 of the first transmission lines 150 are respectively connected to the first transmission pillars 130, and the driving circuit 300 is connected to the second ends 154 of the first transmission lines 150. Similarly, each of the second transmission lines 160 has a third end 162 and a fourth end 164. The third ends 162 of the second transmission lines 160 are respectively connected to the second transmission pillars 140, and the driving circuit 300 is connected to the fourth ends 164 of the second transmission lines 160.
[0038] In response to the size of the driving circuit 300, the first ends 152 of the first transmission lines 150 are arranged at a first pitch P1, the second ends 154 of the first transmission lines 150 are arranged at a second pitch P2, and the first pitch P1 is greater than the second pitch P2. Similarly, the third ends 162 of the second transmission lines 160 are arranged at a third pitch P3, the fourth ends 164 of the second transmission lines 160 are arranged at a fourth pitch P4, and the third pitch P3 is greater than the fourth pitch P4.
[0039] In some embodiments, the plurality of fourth ends 164 of the plurality of second transmission lines 160 are disposed between the plurality of second ends 154 of the plurality of first transmission lines 150 to divide the plurality of second ends 154 of the plurality of first transmission lines 150 into two groups, namely, the second ends 154A and the second ends 154B. The second ends 154A and the second ends 154B are respectively located on opposite sides of the fourth end 164. In some embodiments, the number of the second ends 154A and the number of the second ends 154B are the same, but the present invention is not limited thereto.
[0040] In some embodiments, the wiring paths of the first transmission line 150 and the second transmission line 160 do not overlap or intersect. The first transmission line 150 and the second transmission line 160 may be formed of the same conductive layer. The first transmission line 150 and the second transmission line 160 are substantially arranged in the same plane. In some embodiments, the first transmission line 150 and the second transmission line 160 may be fabricated on the second surface 114 of the substrate 110 by deposition combined with lithography and etching. In some embodiments, the first transmission line 150 and the second transmission line 160 may be fabricated on the second surface 114 of the substrate 110 by printing.
[0041] Figure 5 FIG. 1 is a partial cross-sectional schematic diagram of a pixel array substrate in a display device according to an embodiment of the present invention. Figure 5 The cross-sectional diagram is used to understand the structure of the transmission element and can be used as Figure 2 A possible implementation of the first transmission member 130 and the second transmission member 140 is shown, and some components are omitted. Figure 5In the embodiment, the substrate 110 has a first surface 112 and a second surface 114 opposite to each other. The first signal line 122 of the pixel array 120 is disposed on the first surface 112, and the first transmission line 150 is disposed on the second surface 114. The substrate 110 has a through hole VA, and the through hole VA, for example, passes through the entire thickness of the substrate 110. The metal material filled in the through hole VA constitutes the first transmission column 130. Therefore, the first transmission column 130 is disposed in the through hole VA and extends continuously from the first surface 112 to the second surface 114. The first transmission column 130 has an end face width WT on the first surface 112 and an end face width WB on the second surface. The end face width WT may be greater than the end face width WB. In other embodiments, the end face width WT may be less than or equal to the end face width WB. Figure 2 The individual lateral dimension W140 of the first transmission pillar 130 (or the second transmission pillar 140 ) in FIG. 1 can be understood as the end surface width WT of the first transmission pillar 130 (or the second transmission pillar 140 ) on the first surface 112 .
[0042] In addition, the first transmission pillar 130 is separated from the first edge E1 of the substrate 110 by a distance and is not exposed at the first edge E1. Therefore, the first transmission pillar 130 is buried in the substrate 110 and is laterally surrounded by the substrate 110. In some embodiments, the first transmission pillar 130 may have a variable width, such as being wide at both ends and narrow in the middle, or vice versa.

Figure 6 and Figure 7 The pixel array substrate 100' includes a substrate 110, a pixel circuit array 120, a plurality of first transmission pillars 230, a plurality of second transmission pillars 240, a plurality of first transmission lines 250, and a plurality of second transmission lines 260, wherein the substrate 110 and the pixel circuit array 120 are substantially similar to the aforementioned embodiment, and therefore the substrate 110 and the pixel circuit array 120 can be understood with reference to the description of the aforementioned embodiment. The substrate 110 has a first surface 112 and a second surface 114 opposite to each other, wherein Figure 6 The first surface 112 of the substrate 110 and the components disposed thereon are presented. Figure 7 The second surface 114 of the substrate 110 and the components disposed thereon are presented.
[0044] Similar to the above-mentioned embodiment, the pixel circuit array 120 may include a plurality of first signal lines 122, a plurality of second signal lines 124, a plurality of signal transmission lines 126, and a plurality of active devices 128. The first signal lines 122 each extend along the first direction D1 and are connected to one of the plurality of first transmission pillars 230. The plurality of second signal lines 124 each extend along the second direction D2 and are each connected to a corresponding one of the signal transmission lines 126. The signal transmission lines 126 each extend along the first direction D1 and are each connected to a corresponding one of the second transmission pillars 240.
[0045] In the present embodiment, the substrate 110 has a first edge E1, a second edge E2, a third edge E3 and a fourth edge E4, and the pixel circuit array 120 disposed on the substrate 110 is located in the display area AA, and the area between the display area AA and the above edges can be regarded as the peripheral area PA. The plurality of first transmission columns 230 and the plurality of second transmission columns 240 can each penetrate the substrate 110 and be electrically connected to the pixel circuit array 120. In addition, the plurality of first transmission columns 230 and the plurality of second transmission columns 240 are all located between the pixel circuit array 120 and the same edge (e.g., the second edge E2) of the substrate 110, but not limited thereto. In addition, the plurality of first transmission columns 230 and the plurality of second transmission columns 240 can be arranged in an alternating manner, and need not be limited to being arranged on the same straight line track. One of the plurality of first transmission columns 230 and the plurality of second transmission columns 240 is closer to the edge of the substrate 110 than the other. For example, the plurality of first transmission columns 230 are closer to the second edge of the substrate 110 than the plurality of second transmission columns 240, but not limited thereto.
[0046] exist Figure 7 In the embodiment, each of the plurality of first transmission lines 250 can be connected between one of the plurality of first transmission pillars 230 and the driving circuit 300, and each of the plurality of second transmission lines 260 can be connected between one of the plurality of second transmission pillars 240 and the driving circuit 300. The plurality of first transmission pillars 230, the plurality of second transmission pillars 240, the plurality of first transmission lines 250 and the plurality of second transmission lines 260 are used to establish electrical transmission between the pixel circuit array 120 and the driving circuit 300. The first transmission lines 250 and the second transmission lines 260 are used to transmit different types of signals. In some embodiments, the driving circuit 300 can be designed to centrally arrange the contacts of the same type of signals. Figure 7 As shown, in order to connect to corresponding contacts of the driving circuit 300 , the second transmission line 260 extends, for example, toward a middle section of the driving circuit 300 , while the first transmission line 250 extends, for example, toward an outer section of the driving circuit 300 .
[0047] In the present embodiment, at least one of the first transmission lines 250 and at least one of the second transmission lines 260 may be interlaced with each other. Therefore, the plurality of first transmission lines 250 and the plurality of second transmission lines 260 may be different conductive layers. In other words, the present embodiment may form at least two conductive layers and an insulating layer sandwiched between the two conductive layers on the second surface 114, thereby realizing the required circuit connection layout. In summary, the display device and the display driving circuit device of the embodiment of the present invention are provided with transmission columns penetrating the substrate on the pixel array substrate and the transmission columns are provided on opposite sides of the display area to transmit signals of different signal lines. The display device may have a narrow frame width, and in particular, the frame width at each edge may be quite narrow, thereby realizing a structure with a full-circle narrow frame.
