Problems solved by technology

However, the driving TFTs of existing small-sized OLED display panels are generally made of LTPS brittle silicon-based materials, which have low bending strength. After bending, the characteristics of the TFT device in the folding area will drift or fail, resulting in abnormal display screens.

Abstract

The invention provides a foldable display panel and a manufacturing method thereof. The panel includes a foldable region and a non-foldable region on both sides of the foldable region, wherein the foldable region is internally provided with a substrate and at least one first film transistor layer on the substrate, the non-foldable region is internally provided with a substrate and at least one second film transistor layer on the substrate, and the bending strength of the first film transistor layer is greater than the bending strength of the second film transistor layer. The panel is advantaged in that the first film transistor in the foldable region is made of a material with higher bending strength, which makes bending resistance in the foldable region is better than the non-foldable region, failure of a driving circuit of the foldable display panel is avoided, and a technical problem of abnormal display frames of products is eliminated.

Description

technical field [0001] The present application relates to the field of display, and in particular, to a foldable display panel and a manufacturing method thereof. Background technique [0002] With the development of science and technology, the appearance of mobile electronic devices has undergone tremendous changes, among which, flexible screens have attracted much attention due to their unique characteristics and great potential. Compared with traditional screens, flexible screens have the characteristics of strong flexibility and bendability, which can reduce the degree of accidental damage to equipment, and are much more durable than other screens. [0003] The foldable display panel includes a folding area, so the film layer structure in the folding area needs to have certain bending resistance. However, the driving TFTs of the existing small-sized OLED display panels are generally LTPS brittle silicon-based materials with low bending strength. After bending, the chara...
