Abstract

The invention discloses a display module and a display device, the display module comprises a fingerprint identification module and a display panel which are stacked, and the display panel comprises an array substrate, a light-emitting function layer and a light resistance layer which are sequentially stacked in the direction away from the fingerprint identification module; the array substrate comprises a thin film transistor, the light-emitting functional layer comprises a pixel definition layer and light-emitting units electrically connected with the thin film transistor, and the light resistance layer comprises a black matrix; the black matrix comprises pixel openings corresponding to the light-emitting units, color stop blocks are arranged in the pixel openings, and a first through hole is formed in the area, corresponding to the fingerprint recognition module, of the black matrix. According to the display module, the first through hole is formed in the black matrix, light reflected by a finger can reach the fingerprint identification module through the first through hole, the situation that the light flux reaching the fingerprint identification module is reduced due to the fact that the black matrix shields the light is avoided, and normal operation of the fingerprint identification function in the display module is guaranteed.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] AMOLED (Active-Matrix Organic Light Emitting Diode, Active-Matrix Organic Light Emitting Diode) display devices have the advantages of wide color gamut, fast color change reflection rate, and low energy consumption, and have been more and more widely used in recent years. In order to reduce the thickness of the AMOLED display panel, the existing AMOLED display panels generally use photoresist materials such as color filters and black matrixes to replace polarizers for light filtering. [0003] The under-display optical fingerprint recognition technology can realize functions such as fingerprint unlocking and fingerprint password payment, etc., and is currently widely used in AMOLED display devices. [0004] However, although the use of photoresist material reduces the thickness of the AMOLED display ...
