Abstract: The technical field of liquid crystal display panels is related to, and an in-cell touch panel is provided. The in-cell touch panel includes a first substrate, a conductive line, an alignment film, a spacer, and a second substrate sequentially from bottom to top, and further includes a black matrix covering the conductive line. Without changing a total contact area between a first contact surface of the spacer and the conductive line, the spacer can be arranged to completely stand on the conductive line by changing a shape of the first contact surface. When the panel is made thinner or is pressed, contact and friction between the spacer and the alignment film around the conductive line can be avoided, and large-area non-uniform liquid crystal alignment can be avoided. An area of the black matrix arranged around the spacer can be greatly reduced, and accordingly an aperture ratio of pixels can be improved.

Abstract: A GOA circuit includes GOA circuit units. Each GOA circuit has a holding module A first transistor and a second transistor in the holding module holds the voltage imposed on the first control node to be at high voltage level. Also, the transistors form a direct current passage between the first control node and a first fixed voltage at high voltage level so the voltage imposed on the first control node is not lowered due to electricity leakage. The GOA circuit unit can resolve the problem of easy leakage of electricity. When the scanning signals are output by the GOA circuit unit, the stability is highly ensured.

Abstract: The present invention proposes a TFT, an array substrate, and a method of forming a TFT. The TFT includes a substrate, a buffer layer, a patterned poly-si layer, an isolation layer, a gate layer, and a source/drain pattern layer. The poly-si layer includes a heavily doped source and a heavily doped drain, and a channel. The gate layer includes a first gate area and a second gate area. The source/drain pattern layer includes a source pattern, a drain pattern and a bridge pattern, with the source pattern electrically connecting the heavily doped source, the drain pattern electrically connecting the heavily doped drain, and one end of the bridge pattern connecting the first gate area and the second gate area. The driving ability of the present inventive TFT is enhanced without affecting the leakage current.
