Support plate and foldable display module

Abstract

The application provides a support plate and a foldable display module, the support plate has a bending area and a non-bending area, the bending area includes a parting area and a half-etching area, and the part of the support plate corresponding to the parting area is provided with multiple A hollow structure, the part of the support plate corresponding to the half-etched area is provided with a plurality of groove structures, by controlling at least one of the size of the hollow structure in the parting area, the distance from the edge of the support plate, and the distance between adjacent hollow structures And the groove structure that does not penetrate the support plate is arranged, so that the bending modulus of the part of the support plate corresponding to the parting area and the half-etched area changes regionally, and the transition of the support plate from the parting area to the non-bending area is smoother. , and the radian is more continuous, so as to reduce the stress on the part of the flexible display panel corresponding to the half-etched area, thereby reducing the risk of debonding of the film layer in the foldable display module in the half-etched area.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a support plate and a foldable display module. Background technique [0002] The organic light emitting diode (OLED) display technology can independently emit light without the need for a backlight, so that the overall thickness of the OLED display module stack is greatly reduced, and the screen becomes easier to bend. With the continuous breakthrough of various OLED technologies, flexible displays have entered the stage of commercialization. In recent years, various terminal manufacturers have successively launched foldable and curly display electronic products, but the high selling price has led to lower-than-expected product sales, and the commercial market of 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 the price r...
