Abstract

The invention provides an active element, a pixel structure, a driving circuit and a display panel. The pixel structure comprises a scanning cable, a data cable, the active element, a first insulation layer, a pixel electrode, a capacitor electrode and a second insulation layer. The active element comprises a grid, a gully, a source and a drain, wherein the scanning cable is electrically connected with the grid, and the source is electrically connected with the data cable. The first insulation layer is arranged between the grid and the gully. The pixel electrode is electrically connected with the drain. The capacitor electrode is arranged on the first insulation layer. The second insulation layer covers the first insulation layer and the capacitor electrode, and is arranged between the capacitor electrode and the drain.

Description

technical field [0001] The invention relates to an active element, a pixel structure, a driving circuit 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 display data corresponding to the pixel is displayed by providing an appropriate operating voltage. In addition, the pixel structure also includes a 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 a storage capacitor in the pixel structure, it ...
