AI Technical Summary

Problems solved by technology

Both liquid crystal displays and active organic light-emitting displays require thin-film transistors as driving devices. The traditional thin-film transistor structure includes multiple layers of inorganic thin films prepared by chemical vapor deposition. The general material is SiO 2 , SiON or SiNx, etc. These inorganic thin films are brittle materials. When the bending radius of the display screen gradually shrinks, it is easy to cause cracks, which will lead to the failure of the thin film transistor or the breakage of the metal wire, which will affect the performance of the display panel.

Abstract

The invention provides a display panel. The display panel comprises a flexible substrate, a buffer layer, a thin film transistor layer, a planarization layer, a first electrode and a pixel limiting layer, the thin film transistor structure and the inorganic film layer of the folding display area are moved out and filled with organic materials to form a first organic layer, and when the display panel is bent, the film layer of the folding display area cannot be broken; the thin film transistors, close to the folding display area, of the main display area serve as devices for driving image display of the folding display area, image display of the folding display area is not affected, and in the main display area, the first electrodes are connected with the adjacent thin film transistors, namely, the connection corresponding relation extends towards the periphery.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel. Background technique [0002] With the continuous evolution of display technology, flexible display screens have the advantages of lightness, thinness and shape variability compared with traditional rigid display screens, so the market share is increasing year by year. Folding display is one application mode of flexible screen. In order to minimize the thickness of the folding display, the smaller the bending radius of the folding area of ​​the screen, the more competitive it is. Both liquid crystal displays and active organic light-emitting displays require thin-film transistors as driving devices. The traditional thin-film transistor structure includes multiple layers of inorganic thin films prepared by chemical vapor deposition. The general material is SiO 2 , SiON or SiNx, etc. These inorganic thin films are brittle materials. When the bending radius of th...
