Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0022] see figure 1 , figure 1 It is a display screen 100 provided by the embodiment of the present invention. The display screen 100 includes a display layer 110 and a blocking layer 120 . The display layer 110 is a part of the display screen 100 for displaying images. The display layer 110 has a display surface 111 facing the user, and the barrier layer 120 is stacked on the display surface 111 . The barrier layer 120 includes a fingerprint identification area 121, and the fingerprint identification area 121 includes at least one first through hole 122, and the first through hole 122 is used to transmit the fingerprints transmitted and received by the fingerprint module located below the display screen. induction signal.

Abstract

The invention provides a display screen. The display screen comprises a display layer and a blocking layer, wherein the display layer is provided with a displaying face facing a user, the blocking layer is arranged on the displaying face in a stacked mode, the blocking layer comprises a fingerprint recognition region, the fingerprint recognition region comprises at least one first through hole, and the first through holes are used for transmitting induction signals transmitted and received by a fingerprint module below a display screen. The invention provides a display device, the display device comprises a display screen and an optical fingerprint module, and the optical fingerprint module is arranged at the side, away from the blocking layer, of the display layer and is located at the position corresponding to the optical fingerprint recognition region. The fingerprint module comprises an optical transmitting device and an optical inductor, and light signals transmitted by the optical transmitting device are conveyed to the fingerprint lines through the first through holes and are received by the optical inductor through the first through holes after being reflected by the fingerprint lines. The invention further provides a mobile terminal, and the recognition efficiency of the optical fingerprint module is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a display screen, a display device and a mobile terminal. Background technique [0002] In the prior art, the fingerprint identification module is disposed outside the display area of ​​the display panel to avoid obstructing the display. However, such a structural design makes the screen-to-body ratio (the ratio of the display area to the entire display screen) of the display area smaller. The screen-to-body ratio can be increased by stacking the fingerprint module and the display screen. However, under this structure, the display screen will block the sensing signal of the fingerprint module, resulting in low efficiency for the fingerprint module to collect fingerprints. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a display screen, a display device and a mobile terminal to improve the fingerp...
