Embodiment Construction

[0040] In the display device, the light-emitting device, the adhesive layer and the fingerprint identification module are stacked. The adhesive layer includes an aperture area and a non-aperture area. The reflected light intensity of the non-aperture area is different, so that the light intensity received by the area corresponding to the open area in the TFT array layer of the light-emitting device is greater than the light intensity received by the area corresponding to the non-aperture area. The TFT array layer is different. The light-induced variables of the regions are different, thereby affecting the display effect of the display device.

[0041] In view of the above defects, the embodiment of the present invention provides an improved technical solution. In this technical solution, by setting the adjustment layer on the adhesive layer, the reflectivity and the reflectivity of the interface between the adjustment layer and the opening area of ​​the adhesive layer The refl...

Abstract

The invention provides a display device, relates to the technical field of display, and is used for solving the technical problem of uneven brightness of the display device. The display device comprises a light-emitting device, an adjusting layer, a first bonding layer and a fingerprint recognition module which are arranged in a stacked mode. The first bonding layer comprises an open pore area anda non-open pore area, and the open pore area is opposite to the fingerprint identification module; a first interface between the adjusting layer and the open pore area has a first reflectivity, a second interface between the adjusting layer and the non-open pore area has a second reflectivity, and a difference value between the first reflectivity and the second reflectivity is smaller than a setvalue, so that the first reflectivity is close to the second reflectivity, the intensity of the reflected light between the adjusting layer and the perforated area is close to the intensity of the reflected light between the adjusting layer and the non-perforated area, the intensity of the reflected light received in the light-emitting device is close, namely, the difference of light-induced variables of all areas in the TFT array layer of the light-emitting device is reduced, the brightness of the light-emitting device is uniform, and the display effect of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the development of display technology, a display device with a higher screen-to-body ratio can provide a better visual experience, and has gradually become a mainstream development direction, such as a display device with a full screen. [0003] The display screen of the display device is usually unlocked by using a Fingerprint on Display (FOD for short) technology. The under-screen fingerprint technology places the fingerprint identification module under the display screen, and realizes fingerprint identification by placing the finger on the display screen. The display device usually includes a display screen and a fingerprint recognition module arranged under the display screen. The display screen and the fingerprint recognition module are connected by an adhesive layer. The adhesive layer usually includes an apertu...
