Abstract: Provided is a display panel, comprising a substrate, and a display area and a non-display area formed on the substrate; wherein metal traces are disposed on one side of the non-display area to electrically connect an integrated circuit in the non-display area with an external structure integrated with a driver integrated circuit (IC) for driving the integrated circuit in the non-display area by the external structure integrated with the driver IC to illuminate the display area. By bonding the driver IC to the external structure, the area ratio of the bonding area of the driver IC on the display panel is reduced to increase the screen occupation ratio of the display panel.

Abstract: A manufacturing method of a TFT substrate uses a top gate structure and the entire process can be completely done with seven masks. The number of masks used is reduced. The manufacturing process of a TFT substrate is simplified. Product yield can be increased to effectively improve productivity. Heavy and light ion doping can be simultaneously achieved with one single doping operation so that manufacturing cost can be reduced. By subjecting two ends of a semiconductor pattern to heavy ion doping to form a source electrode and a drain electrode, the manufacturing steps can be reduced and the source electrode and the drain electrode so formed do not need to extend through a via hole formed in an interlayer dielectric layer to contact the two ends of the active layer thereby effectively reducing contact resistance and improving product yield. Also provided is a TFT substrate manufactured with the method.

Abstract: The present disclosure provides a liquid crystal display and a display module thereof, the display module includes a lower polarizer, a TFT array substrate, a liquid crystal layer, a color filter and a upper polarizer. The display module further includes a metal electrode layer arranged between the color filter and the liquid crystal layer, the metal electrode layer includes a dielectric layer and a metal wire grid layer, and the metal wire grid layer is arranged on a surface of the dielectric layer facing the liquid crystal layer. The metal wire grid layer is used as a common electrode layer of the display module, thus replacing the traditional transparent electrode ITO and avoiding the problem that the transparent electrode ITO easily causes brittle fracture during bending resulting in electrical abnormality and at the same time can improve the contrast of the entire liquid crystal display.

Abstract: The present disclosure proposes a method of producing an LTPS TFT array substrate. The method is about stacking of a gate insulating layer and an interlayer insulating layer for providing conditions for formation of a gate trench. In addition, stacking of the gate insulating layer and the interlayer insulating layer is produced with some blocks of forming a hole on the gate insulating layer and the interlayer insulating layer to form a hole pattern, filling the gate trench, and producing gate lines. In this way, the formation of the gate lines and the formation of the hole pattern on the gate insulating layer and the interlayer insulating layer are done using the same mask. The method of the present disclosure reduces the number of masks required compared with the method of the related art, thereby reducing the production costs.

Abstract: The present invention provides a TFT substrate manufacturing method and a TFT substrate. In the TFT substrate manufacturing method of the present invention, a pattern of the gate metal layer has been designed such that reflective blocks are included in a gate metal layer at locations corresponding to areas in which connection holes are to be formed so that in a process of forming the connection holes, light is reflected by the reflective blocks to enhance intensity of exposure on locations where the connection holes are formed. Thus, even under the condition that limit exposure size of an existing exposure machine is constrained, it is still possible to ensure full exposure in forming the connection holes in a high PPI display panel device to thereby realize production of high display panel products.
