Abstract: A GOA circuit includes an output module in which a second TFT is arranged. The second TFT has a drain connected to a source of a first TFT, a gate receiving a first control signal, and a source receiving an Mth clock signal. The first control signal controls the second TFT to turn on and off. Alternatively, the drain of the second TFT is connected to the source of the first TFT, the gate receiving the Mth clock signal and the source connected to the first node to allow the second TFT to be conducted on only when the Mth clock signal is a high voltage and the first node is of a high voltage and is cut off at the remaining time. It is possible to prevent a voltage difference from being induced between the source and drain of the first TFT to reduce the electric current stress.

Abstract: The present invention provides a color conversion layer, a manufacturing method of the color conversion layer, and a display panel. The color conversion layer is used in a display panel having a direct surface light source. The color conversion layer includes a quantum dot film and a functional film. The functional film is arranged at one side of the quantum dot film facing the direct surface light source. A light wave emitted by the direct surface light source is transmitted through the functional film into the quantum dot film. A light wave excited by the quantum dot film is reflected into the quantum dot film through the functional film.

Abstract: A manufacturing method for a liquid crystal display panel is disclosed and includes a step forming a refractive index gradient layer, a step forming a gate electrode insulation layer, a step forming a first interlayer dielectric layer, and a step forming a second interlayer dielectric layer. The step forming a refractive index gradient layer includes depositing a silicon nitride layer on a glass substrate, depositing the refractive index gradient layer on the silicon nitride layer. The refractive index gradient layer is silicon oxide, and includes a lower refractive index decremental layer and a lower refractive index constant layer. A refractive index of the decremental layer gradually decreases along a direction away from the silicon nitride layer, the lower refractive index constant layer is on the lower refractive index decremental layer. A reflection rate between light in film layers can be lowered to improve light transmittance of the display panel.

Abstract: An array substrate and a touch display screen are disclosed in the present disclosure. The array substrate includes a plurality of touch cells, a plurality of touch lines, a first control unit, and a second control unit. Through this way, the present disclosure can solve the problem that touch lines fail to uniformly drive touch cells in each column due to the fact that the number of touch cells in the longitudinal direction is out of proportion with the number of pixel cells in the horizontal direction of each touch cell.

Abstract: A display device, a backlight module and a manufacturing method of a backlight module are provided. The backlight module may include a substrate, a backlight source arranged on the substrate, and a silicone film coated on a light emitting surface of the backlight source. A cross-section of the silicone film along a direction substantially perpendicular to the substrate is an arc to diffuse light emitted by the backlight source. By coating the surface of the backlight source with an arc silicone film, the light angle of the backlight source could be increased, so as to achieve the goal of mixing light with a smaller mixing light distance, which could reduce the thickness of backlight module.

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.
