Abstract

According to the display module and the display device provided by the invention, a flexible circuit board connecting the first circuit board and the second circuit board in the display module is improved, so that the length of the flexible circuit board is greater than the distance between a first connecting port and a second connecting port; therefore, the length required for changing a display panel from the flattened state to the folded state is reserved; the orthographic projection of the flexible circuit board on the first circuit board and the first circuit board have the first overlapping area, and the orthographic projection of the flexible circuit board on the second circuit board and the second circuit board have the second overlapping area, so that the two ends of the flexible circuit board are respectively bent inwards and reversely by a part and then are connected with the corresponding connecting ports; therefore, the flexible circuit board has enough extension space in the dynamic bending process of the display panel, poor microcracks generated during bending can be avoided, the service life of the flexible circuit board is prolonged, and the display performance of a product is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display module and a display device. Background technique [0002] Flexible organic light-emitting diode (OLED) display products are expected to become a new generation of display technology due to their advantages such as self-illumination, no backlight, foldable, wide viewing angle, and high color gamut. At present, OLED folding display products can be flexibly switched between flattened and folded forms, and the circuit boards on both sides of the folding area of ​​the folding display product need to be bridged by a flexible printed circuit (FPC). [0003] However, during the dynamic bending process of the whole machine of the folding display product, the problem of micro-breakage of the FPC wires will occur, which seriously affects the display performance of the product. Contents of the invention [0004] In view of the sho...
