Thin film transistor driving backplane, manufacturing method thereof and display panel

Abstract

The invention relates to the technical field of display, in particular to a thin film transistor driving backplane, a manufacturing method and a display panel. The manufacturing method of the thin film transistor driving backplane comprises the following steps that a backplane substrate provided with a plurality of active device structures is manufactured; an electrode layer is arranged on the backplane substrate; the electrode layer is made into source electrodes, drain electrodes and pixel electrodes by the adoption of the one-time picture composition technology, wherein the pixel electrodes and the drain electrodes are arranged in an integrated mode. According to the manufacturing method, the electrode layer is made into the source electrodes, the drain electrodes and the pixel electrodes by the adoption of the one-time picture composition technology, wherein the pixel electrodes and the drain electrodes are arranged in the integrated mode; therefore, the source electrodes, the drain electrodes and the pixel electrodes are located on the same electrode layer; the prior art that the source electrodes, the drain electrodes and the pixel electrodes are formed through two-time picture composition technology is simplified into the manufacturing method that the source electrodes, the drain electrodes and the pixel electrodes can be formed only through the one-time picture composition technology; the thickness of the thin film transistor driving backplane is greatly reduced, the manufacturing steps are simplified, and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor driving backplane, a manufacturing method thereof, and a display panel. Background technique [0002] With the improvement of people's living standards, people's requirements for display quality are getting higher and higher. Liquid crystal displays (LCDs) have become very mature, and LCDs can be seen in mobile phones, cameras, computers, and televisions. People's large demand for display products objectively promotes the development of display technology, and new display technologies continue to emerge. Active matrix organic light-emitting diode panel (AMOLED) is called the next generation display technology, including Samsung Electronics, LG, Philips all attach great importance to this new display technology. At present, apart from Samsung Electronics, LG, and Philips, whose main direction is to develop large-sized active matrix organic light-emitting d...

Problems solved by technology

However, the existing active matrix organic light-emitting diode panels, especially the thin-film transistor drive backplane used to drive the panel display, its manufacturing process is mainly to form thin-film transistors such as thin-film transistors on each thin-film layer through a patterning process. The graphics required by the device, which requires multiple patterning processes, usually requires more than seven patterning processes to complete, and the capital required for each patterning process is very expensive; therefore, for the production of thin film transistor drive backplanes, Reducing the number of patterning processes is a difficult problem restricting its development
