Abstract

The invention provides a display module and an electronic device. The display module comprises a backlight source and a display panel. The backlight source comprises a first light source for providingvisible light and a second light source for providing invisible light. The display module further comprises a fingerprint sensing layer arranged on the side, away from the backlight source, of the display panel, and the fingerprint sensing layer is used for receiving reflected light reflected by a finger above the display panel. The reflected light is light which is emitted by the second light source, faces the display panel and is obtained after invisible light is reflected. According to the scheme, it can be guaranteed that the light used for sensing the fingerprint reaches the fingerprintsensing layer, so that it is guaranteed that the optical fingerprint module is applied to the display module, and the problem that in the prior art, a display module cannot achieve the optical fingerprint recognition function can be well solved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a display module and electronic equipment. Background technique [0002] In recent years, full-screen mobile phones have become more and more popular, but optical fingerprints, one of the full-screen implementation methods, can only be applied to OLED (organic light-emitting semiconductor) displays. The use of OLED displays has been plagued by supply and price. Therefore, there is a need for an optical fingerprint design scheme that can be applied to TFT (thin film transistor) display screens, so as to realize wider application of optical fingerprints and cost savings. [0003] That is to say, at present, optical fingerprint modules in the industry can only be applied to OLED display modules, but not to TFT display modules. OLED displays are costly and difficult to supply. [0004] Specifically, the reason why the TFT display module cannot apply the existing photoel...
