Problems solved by technology

However, as the resolution increases, the area occupied by the GOA circuits fabricated in the peripheral area must also increase, so that the frame of the flat display panel cannot be further reduced, which affects the development of the narrow frame flat display panel.

Abstract

The present invention provides a thin-film transistor component, a pixel structure and a driving circuit of a display panel. The thin-film transistor component is equipped on a substrate and comprises the following components: a grid, a semiconductor channel layer, a grid insulation layer which is provided between the grid and the semiconductor channel layer, a source and a drain which are respectively provided at two opposite sides of the semiconductor channel layer and are overlapped with the semiconductor channel layer partially, a capacitor electrode which is at least partially overlapped with the grid part, and a capacitive dielectric layer which is provided between the capacitor electrode and the grid. The capacitor electrode, the grid and the capacitive dielectric layer form a capacitor component.

Description

technical field [0001] The present invention relates to a thin film transistor element and a pixel structure and a driving circuit of a display panel, in particular to a thin film transistor element having a gate vertically overlapped with a capacitor electrode to form a capacitive element, and a display panel provided with the above thin film transistor element The pixel structure and driving circuit. Background technique [0002] Flat display panels, such as liquid crystal display panels, have replaced traditional cathode ray tube displays and become mainstream products in the display market due to their thin, light, small, low radiation, and low power consumption characteristics. In the development of flat panel display panels, narrow bezel design and high-resolution specifications are the two major development trends. In the current flat panel display panel, in order to reduce the number of driving chips, a method of integrating the gate driving circuit on the array sub...
