Abstract:
A manufacturing method of a thin film transistor array substrate incorporating the manufacture of a photo-sensor is provided. In the manufacturing method, a photo-sensing dielectric layer is formed between a transparent conductive layer and a metal electrode for detecting ambient light. Since the transparent conductive layer is adopted as an electrode, the ambient light can pass through the transparent conductive layer and get incident light into the photo-sensing dielectric layer. Therefore, the sensing area of the photo-sensor can be enlarged and the photo-sensing efficiency is improved. In addition, the other side of the photo sensitive dielectric layer may be a metal electrode. The metal electrode can block the backlight from getting incident into the photo-sensing dielectric layer and thus reduce the background noise. A manufacturing method of a liquid crystal display panel adopting the aforementioned thin film transistor array substrate is also provided.
Abstract:
A pixel structure including at least one thin-film transistor, at least one storage capacitor, a patterned first metal layer, an interlayer dielectric layer, a passivation layer, and a patterned pixel electrode is provided. The storage capacitor is electrically connected to the thin-film transistor. The patterned first metal layer is covered by the interlayer dielectric layer. The thin-film transistor and the interlayer dielectric layer are covered by the passivation layer, wherein an opening is formed in the passivation layer and a part of the interlayer dielectric layer. The patterned pixel electrode is formed on a part of the passivation layer and a part of the interlayer dielectric layer and contacted with a part of the passivation layer and a part of the interlayer dielectric layer. The storage capacitor includes the patterned first metal layer, a remained part of the interlayer dielectric layer located under the opening, and the patterned pixel electrode.
