Abstract: A TFT array panel includes a primary display area and a slitting-edge display area. In the slitting-edge display area, a first metallic routing layer includes a first data line and a second metallic routing layer includes a first gate line. The first data line is connected to the second metallic routing layer through a hole in the interlayer dielectric layer so that the first data line overlaps the first gate line to form an overlapping capacitance to compensate for a gate line RC value.

Abstract: A flexible display panel is provided and defined with a special-shaped cutout area and a display area, including a substrate, and a plurality of pixel structures, a scan line layer, and a data line layer disposed above the substrate, wherein each of the plurality of the pixel structures includes three sub-pixels, and the scan line layer includes a plurality of scan lines, and the data line layer includes a plurality of data lines. The sub-pixels are arranged as an array over the substrate, and the scan lines and the data lines are disposed in the array of the sub-pixels. A scan line is disposed between every two rows of the sub-pixels and two data lines are disposed between every column of the sub-pixels in the special-shaped cutout area. Therefore, the frame of the special-shaped cutout area can be reduced to realize the narrow frame of the special-shaped cutout area.

Abstract: An array substrate includes a substrate, a buffer layer, a first shielding pattern, a passivation layer, a first semiconductor pattern, a gate insulating layer, a first gate pattern, an interlayer insulating layer, and two first source/drain electrode patterns. A first through hole and a second through hole are arranged on the array substrate. One of the first source/drain electrode patterns is electrically connected to the first semiconductor pattern and the first shielding pattern through the first through hole. The other one of the first source/drain electrode patterns is electrically connected to the first semiconductor pattern through the second through hole and is insulated from the first shielding pattern. The present invention where the array substrate and the method of forming the array substrate are proposed is related to a top-gate design. The driving ability of the TFT driving circuit still improves without increasing the original processes and production costs.

Abstract: A display panel and a method for testing for an occurrence of a crack in a display panel are provided. The display panel includes a panel body, a ground line, a first ground connecting portion, a first testing portion, a second ground connecting portion, a second testing portion, and a switch. By measuring a voltage, a resistance, or a current between the first testing portion and the second testing portion, an open circuit in the ground line and a crack in a non-display area can be detected. Therefore, difficulty of confirming if a crack occurs in the display panel is reduced.
