Problems solved by technology

[0003] In the prior art, the fingerprint recognition function in the display area is realized by placing the fingerprint recognition sensor between the touch sensor units. The disadvantages of this technology are: 1. The wiring of the fingerprint recognition sensor cannot be connected from the touch sensor to the Controller; 2. The fingerprint recognition sensor increases the load of the touch sensor, which affects the touch function; 3. The fingerprint recognition sensor has high process requirements, and the current touch sensor process cannot meet the requirements; 4. Due to the fingerprint sensor The addition of will reduce the transmittance of the display

Abstract

The invention provides a display panel. The display panel comprises a fingerprint identification sensor, a fingerprint identification controller, a substrate, a switch control layer, a display signal routing layer and an electrode layer which are orderly formed at one side of the substrate; the fingerprint identification sensor is integrated in the electrode layer to form a fingerprint identification and electrode common layer; and switch routing of the switch control layer and display signal routing of the display signal routing layer are respectively electrically connected with the fingerprint identification controller. According to the display panel provided by the invention, the fingerprint identification function can be integrated into the display panel, so that the fingerprint identification function in a display area can be realized. The invention further provides a mobile terminal.

Description

technical field [0001] The invention relates to fingerprint identification technology, in particular to a display panel and a mobile terminal. Background technique [0002] At present, the fingerprint identification device has gradually become a standard device for mobile terminals, and even some other terminals. The position of the fingerprint identification device on the terminal and the convenience of use have attracted more and more attention. The fingerprint identification function is integrated into the display area to improve User experience has become the goal of the industry. [0003] In the prior art, the fingerprint recognition function in the display area is realized by placing the fingerprint recognition sensor between the touch sensor units. The disadvantages of this technology are: 1. The wiring of the fingerprint recognition sensor cannot be connected from the touch sensor to the Controller; 2. The fingerprint recognition sensor increases the load of the tou...
