FIG. 2 is a schematic view of a front side of a pixel array substrate according to an embodiment of the disclosure, and FIG. 3 is a schematic view of a rear side of a pixel array substrate according to an embodiment of the disclosure. Please refer to FIG. 2 and FIG. 3 at the same time. The pixel array substrate 100 includes a support plate 110, a pixel circuit array 120, multiple first transmission pillars 130, multiple second transmission pillars 140, multiple first transmission lines 150, and multiple second transmission lines 160. The first transmission pillars 130 and the second transmission pillars 140 may each penetrate the support plate 110 and be electrically connected to the pixel circuit array 120. In FIG. 3, the first transmission lines 150 may be each connected between one of the first transmission pillars 130 and the driving circuit 300, and the second transmission lines 160 may be each connected between one of the second transmission pillars 140 and the driving circuit 300. In other words, the first transmission lines 150 and the second transmission lines 160 are all electrically connected to the driving circuit 300, and the first transmission pillars 130, the second transmission pillars 140, the first transmission lines 150, and the 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 first transmission lines 150 and the second transmission lines 160 may overlap with a display area AA of the display device 10 (that is, overlap with the display layer 200), and a peripheral area PA of the display device 10 may be very narrow. Here, the display area AA may be an area defined by the outline of the display layer 200 (shown in FIG. 1), and the peripheral area PA may be edges of the display area AA to edges (a first edge E1, a second edge E2, a third edge E3, and a fourth edge E4) of the support plate 110, but not limited thereto.

The support plate 110 has a first surface 112 and a second surface 114 opposite to each other, wherein FIG. 2 shows the first surface 112 of the support plate 110 and components disposed thereon. FIG. 3 shows the second surface 114 of the support plate 110 and components disposed thereon. The support plate 110 is a plate having sufficient mechanical support. The support plate 110 is, for example, a glass plate, a plastic plate, etc. In some embodiments, the support plate 110 may be light transmissive, but may also be selectively a non-light-transmissive plate.

The support plate 110 has a rectangular shape and includes the first edge E1, the second edge E2, the third edge E3, and the fourth edge E4. The first edge E1 is opposite to the second edge E2 in a first direction D1, and the third edge E3 is opposite to the fourth edge E4 in a second direction D2. In the embodiment, the first direction D1 is substantially parallel to a direction from the first edge E1 of the support plate 110 to the second edge E2 of the support plate 110, and the second direction D2 is substantially parallel to a direction from the third edge E3 of the support plate 110 to the fourth edge E4 of the support plate 110.

The pixel circuit array 120 is disposed on the first surface 112 of the support plate 110. In FIG. 2, the pixel circuit array 120 may include multiple first signal lines 122, multiple second signal lines 124, multiple signal transmission lines 126, and multiple active elements 128. The first signal lines 122 each extends along the first direction D1 and are each connected to one of the first transmission pillars 130. The second signal lines 124 each extends along the second direction D2 and are each connected to a corresponding signal transmission line 126. The signal transmission lines 126 each extends along the first direction D1 and are each connected to a corresponding second transmission pillar 140. The active elements 128 are each connected to a corresponding one of the first signal lines 122 and a corresponding one of the second signal lines 124. The first direction D1 and the second direction D2 may intersect each other, such as being orthogonal, but not limited thereto.

In some embodiments, the first signal lines 122 transmit one of a scan signal and a data signal, and the second signal lines 124 transmit the other one 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 also include a capacitor connected to the individual active element 128. In some embodiments, the pixel circuit array 120 may further include a touch element, a sensing element, an image capturing element, a vibration element, or other elements for providing individual functions.

In the embodiment, the first signal line 122 extends along the first direction D1 to the corresponding first transmission pillar 130 and may be then electrically connected to the first transmission line 150 on the second surface 114 through the first transmission pillar 130. Therefore, the first signal line 122 need not 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 may be then electrically connected to the second transmission line 160 on the second surface 114 through the second transmission pillar 140. Therefore, the second signal line 124 need not extend beyond the second transmission pillar 140. As shown in FIG. 2, the first transmission pillar 130 and the second transmission pillar 140 may be roughly 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 support plate 110 and the peripheral area PA between the display area AA and the second edge E2 of the support plate 110 may be very narrow, which helps to achieve a narrow frame design in the first direction D1. In some embodiments, a width WD1 of the peripheral area PA between the display area AA and the first edge E1 (or the second edge E2) of the support plate 110 may be less than twice an individual horizontal dimension W140 of the first transmission pillar 130 and the second transmission pillar 140.

In the embodiment, the second signal line 124 extends along the second direction D2 and is connected to the active elements 128 arranged in the second direction D2. Meanwhile, each of the signal transmission lines 126 may be connected to one of the second signal lines 124 through a corresponding connection contact CT. Each signal transmission line 126 may extend between one of the connection contacts CT and one of the second transmission pillars 140. However, in some embodiments, the signal transmission line 126 may also selectively extend beyond the corresponding connection contact CT. In FIG. 1, two adjacent connection contacts CT are not on the same second signal line 124. The connection contacts CT are arranged along a diagonal path, but may be arranged along a V-shaped path or a zigzag path in other embodiments.

The second signal line 124 and the signal transmission line 126 connected through the connection contact CT may 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 may provide a narrow peripheral area PA in the second direction D2, thereby also implementing a narrow frame in the second direction D2. In some embodiments, a width WD2 of the peripheral area PA between the display area AA and the third edge E3 (or the fourth edge E4) of the support plate 110 in the second direction D2 may be less than the individual horizontal dimension W140 of the first transmission pillar 130 and the second transmission pillar 140.

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 staggered 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, 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 contact CT may penetrate the at least one insulating layer, so that the signal transmission line 126 may 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.

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.

In response to the dimensions 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.

The second end 154A and the second end 154B are respectively located on two opposite sides of the fourth end 164. In some embodiments, the numbers of the second end 154A and the second end 154B are the same, but not limited thereto.

In some embodiments, the wiring paths of the first transmission lines 150 and the second transmission lines 160 do not overlap or are not staggered. The first transmission line 150 and the second transmission line 160 may be composed of the same conductive layer. The first transmission line 150 and the second transmission line 160 are substantially disposed on the same plane.
