Abstract: A touch panel metal grid structure with augmented mutual capacitance includes a substrate, a driver layer, a detection layer, and a capacitance detection device. The driver layer is disposed on the substrate. The driver layer includes a plurality of circular patterns and each two said circular patterns are connected together by using a bridge wire. The detection layer is disposed on the substrate. The detection layer includes a plurality of polarized quadrilateral patterns. Each of the polarized quadrilateral patterns is disposed correspondingly to each of the circular patterns to form a touch-sensing pattern. The capacitance detection device is electrically connected to the detection layer and the driver layer. Therefore, the present invention can enhance touch control signals and can effectively prevent a cathode and other electric fields from interfering in the signals.

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.
