Substrate baseplate, display baseplate, manufacturing method of substrate baseplate and display device

Abstract

The invention relates to the technical field of display and discloses a substrate baseplate, a display baseplate, a manufacturing method of the substrate baseplate and a display device. The manufacturing method comprises the following steps: by forming an intermediate layer on an organic baseplate, setting a coefficient of thermal expansion of the intermediate layer to be smaller than that of the organic baseplate, setting the coefficient of thermal expansion of the intermediate layer to be greater than that of an inorganic thin film and forming the inorganic thin film on the intermediate layer, so that influence of thermal stress of the organic baseplate on the inorganic thin film is buffered, the problems that the inorganic thin film is easy to generate microcracks and is easy to fall down are improved and product yield and display quality of the display device are improved.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a base substrate and a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Traditional displays are flat panel displays and cannot be bent at will. The trend of future display is to realize the display of a large amount of information on a flexible body, that is, flexible display. Flexible display and flexible display modules can be mechanically bent in any step of substrate packaging, production, storage, use, operation, process connection, handling, and transportation. The key technologies for realizing flexible display can be divided into several aspects: display technology, substrate technology, array technology and packaging technology. At present, the substrates that can realize flexible display mainly include ultra-thin glass substrates, metal foil substrates, and plastic substrates. [0003] Among them, t...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a base substrate, a display substrate and a manufacturing method thereof, which are used to solve the problem that the organic substrate and the inorganic thin film have different thermal expansion coefficients, causing the inorganic thin film to easily produce microcracks and fall off.
