Supporting plate and foldable display module

Abstract

The invention provides a supporting plate and a foldable display module, the supporting plate is provided with a bending area and a non-bending area, the bending area comprises a parting area and a semi-etching area, the part, corresponding to the parting area, of the supporting plate is provided with a plurality of hollow structures, and the part, corresponding to the semi-etching area, of the supporting plate is provided with a plurality of groove-shaped structures, by controlling at least one of the size of the hollow structure in the parting area, the distance between the hollow structure and the edge of the supporting plate and the distance between the adjacent hollow structures and arranging a groove-shaped structure which does not penetrate through the supporting plate, the bending modulus of the part, corresponding to the parting area and the semi-etching area, of the supporting plate is changed regionally, the transition of the supporting plate from the parting area to the non-bending area is smoother, and the radian is more continuous, so that the stress borne by the part, corresponding to the half-etching area, of the flexible display panel is reduced, and the risk that a film layer in the foldable display module is debonded in the half-etching area is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a support plate and a foldable display module. Background technique [0002] The organic light emitting diode (OLED) display technology can emit light independently without backlight, so that the overall thickness of the OLED display module stack is greatly reduced, and the screen becomes easier to bend. With continuous breakthroughs in OLED technologies, flexible displays have entered the stage of commercialization. In recent years, various terminal manufacturers have launched folding and roll-up display electronic products one after another, but the high price has caused the product sales to fall short of expectations, and the commercial market for folding mobile phones has not been released quickly. The main factor is that the production yield of flexible OLED display panels has been at a low level, which directly leads to the delay in reducing the price of folding...
