Abstract

The invention provides a display apparatus having a fingerprint identification function, relating to the technical field of display and solving the problems that a finger and a fingerprint identification device are large in distance, and the identification precision is low. The fingerprint identification device includes a plurality of identification units that are arranged in an array, and a light-sensitive element is arranged in each identification unit. The light-sensitive elements perform the photoelectric conversion on the incident light. In addition, the fingerprint identification device further includes a collimating filter layer arranged in the light-receiving sides of the light-sensitive elements. The collimating filter layer includes a plurality of strip-like light guide portions spaced apart and arranged in parallel and irradiate the incident light to the light-sensitive elements in parallel. The display apparatus having the fingerprint identification function is used for fingerprint detection.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device with a fingerprint identification function. Background technique [0002] Human fingerprints are unique and invariant, so fingerprint recognition technology has the characteristics of good security, high reliability, and simple and convenient use, making fingerprint recognition technology widely used in various fields of personal information security protection, especially in display devices. , such as mobile phones, laptops, tablet computers, digital cameras, etc. [0003] In order to make the display device have a fingerprint identification function, such as figure 1 As shown, the fingerprint identification device 01 is usually set in the non-display area A of the display device. When the finger touches the cover glass 02 of the display device at the position corresponding to the fingerprint identification device 01 , the fingerprint identification device 01...
