Description

technical field [0001] The invention relates to an active element, a pixel structure and a display panel with the active element. Background technique [0002] Generally speaking, a pixel structure of a liquid crystal display includes an active element and a pixel electrode. The active element is used as the switching element of the liquid crystal display unit. In order to control individual pixel structures, a specific pixel is usually selected through corresponding scan lines and data lines, and an appropriate operating voltage is provided to display display data corresponding to the pixel. In addition, the pixel structure also includes a storage capacitor (storage capacitor), so that the pixel structure has a voltage holding function. That is, the storage capacitor can store the above-mentioned applied operating voltage to maintain the stability of the display picture of the pixel structure. [0003] In order to provide storage capacitors in the pixel structure, it is ...
