Abstract: An embodiment of the present application discloses a display panel and a display panel manufacturing method. The photosensitive element and the thin film transistor device are disposed on the same side of the substrate. Some components of the photosensitive element and some components of the thin film transistor device can be manufactured by the same step, and therefore can improve integration of the photosensitive element on the array substrate. Furthermore, the photosensitive element can be integrated in the display panel with reduced photomasks and a lowered cost.

Abstract: The present application provides a thin-film transistor having a vertical structure and an electronic device. In the thin-film transistor having the vertical structure, the thin-film transistor includes a first doped portion and a second portion, the second doped portion is connected to and partly in contact with a channel portion through a via hole by arranging the second doped portion in the via hole of an insulating layer, which can reduce a contact area between the second doped portion and the channel portion, thereby reducing ions diffusing into a channel region and improving device stability of the thin-film transistor. Also, in the thin-film transistor having the vertical structure, a projection area of the thin-film transistor can be reduced, improving an aperture ratio of a display panel.

Abstract: A gate driving circuit and a display panel are disclosed. A pull-up control module and a pull-down module of each stage gate driving unit are connected to a first node. A thin film transistor in the pull-up control module and/or pull-down module that is connected to the first node is an oxide thin film transistor, such that a leakage current of the first node is reduced due to the advantage of the small off-state leakage current of the oxide thin film transistor. Therefore, the voltage level of the first node can remain stable during a pull-up stage and a touch suspension stage.

Abstract: The present disclosure proposes a multiplex LCD driving circuit. By setting a new circuit structure, adjacent display pixels of the same color are opposite in polarity in the same row of subpixels. In this way, half of the data lines are applied with positive polarity voltage and half of the data line are applied with negative polarity voltage. Capacitance couplings between the data lines and the common electrodes are balanced off each other, which resolves the display picture abnormality caused by the coupling capacitance between the data line and the common electrode in the LTPS-LCD product.

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.
