Display device with overlapping spacer and scan line
A recently granted patent (Publication Number: US11774804B2) describes a display device with improved design and functionality. The device includes a first substrate and a second substrate positioned opposite to each other. A scan line and a common electrode line are located between the two substrates and are part of the same layer. A spacer is placed between the scan line and the second substrate, overlapping the scan line. The spacer is separated from the scan line by a first insulating layer and a second insulating layer. Additionally, a dummy pad is positioned between the two insulating layers, overlapping the common electrode line.
In this display device, the common electrode line and the scan line extend in the same direction, enhancing their efficiency and performance. The spacer has different widths on each side, with the surface facing the second substrate having a greater width than the surface facing the first substrate. This design feature contributes to the overall stability and functionality of the device.
The display device also includes a thin film transistor that is electrically connected to the scan line. The thin film transistor features a source with a chamfer angle when viewed from the top of the first substrate. This angle enhances the electrical connection and performance of the device.
Furthermore, the display device incorporates another dummy pad adjacent to the scan line, positioned on the opposite side of the scan line from the first dummy pad. The scan line and the other dummy pad are formed from a first conductive layer, while the first dummy pad is made from a second conductive layer, which is different from the first conductive layer.
Overall, this patented display device offers improved design and functionality, with features such as aligned common electrode and scan lines, variable spacer widths, and additional dummy pads for enhanced performance. These advancements contribute to the overall efficiency and effectiveness of the display device.
