Embodiment Construction

[0029] The specific implementation manner of the display device provided by the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] The thickness of each film layer and the shape and size of the region in the drawings do not reflect the true proportion of the display device, and the purpose is only to illustrate the content of the present invention.

[0031] An embodiment of the present invention provides a display device, such as Figure 3a to Figure 3c As shown, it includes: a display panel with a plurality of pixel units 100, a protective cover 200 disposed on the light-emitting surface of the display panel, a plurality of photosensitive devices 300 disposed under the protective cover 200 for texture recognition, and disposed on A plurality of filter structures 400 between the protective cover 200 and the plurality of photosensitive devices 300; wherein,

Abstract

The invention discloses a display device. A filtering structure arranged between a protective cover plate and photosensitive devices is changed into filtering layers which are arranged in a laminated way, each filtering layer includes a light transmission area and a shielding area beyond the light transmission area, central positions of the light transmission areas of the different filtering layers are dislocated partially at least, orthographic projections of the light transmission areas of the different filtering layers in a display panel include an overlapped area, and the area of the overlapped area is the light transmission area of the filtering structure. The dislocation sizes of the central positions of the light transmission areas of the different filtering layers are adjusted to reduce the light transmission area of the filtering structure according to requirements, and thus, the filtering structure is not influenced by precision of manufacturing equipment, and the precision of optical fingerprint identification is improved. After that the light transmission area of the filtering structure is reduced according to requirements, a collimation effect can be ensured, and the filtering structure is prevented from being too thick and further influencing the thickness of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] At present, the devices that realize the texture recognition function installed on display devices such as mobile phones are all in non-display areas such as the home button or the back of the display device, and the future development direction of display devices is ultra-thin, high color gamut, wide viewing angle and integrated Various sensing functions. When the optical sensor (Sensor) that realizes texture recognition is integrated inside the display panel, the distance between the Sensor and the finger contact surface will increase, causing the distance for the reflected light from the finger to reach the Sensor to increase, and the light reflected by the finger will reach the Sensor. Scattering occurs before the Sensor, such as figure 1 As shown, a single optical sensor receives fingerprint information of multiple v...
