Abstract: A display panel is provided, comprising a backlight module, a first substrate, a liquid crystal layer, a second substrate, and a glass cover, wherein the second substrate comprises a fingerprint identification layer configured for identifying information from a fingerprint of a user. The second substrate provided with the fingerprint identification layer is disposed close to the glass cover, making the fingerprint identification layer closer to the fingerprint of the user, shortening a path of the light reflected by the fingerprint to the fingerprint identification sensors, and improving fingerprint identification effectiveness.

Abstract: A display method of a display panel, a display device, and a server are disclosed. The display method divides an initial image into a plurality of sub-frame images having a same frequency, and the frequency of the sub-frame images is a multiple of a frequency of the initial image. The sub-frame images are input into the display panel in sequence and are combined to obtain a target image. The target image is used to drive the display panel to display the initial image, thereby reducing a refresh rate of the display panel for inputting data. Therefore, the display panel can realize low frequency input and prevent frame loss.

Abstract: A method of recognizing a fingerprint is implemented by dividing a sensor matrix of a mobile terminal into a plurality of blocks by rows. Each of the blocks is under control of an independent switch terminal. When performing fingerprint unlocking, only an area covered by the fingerprint is being scanned, while an area not covered by the fingerprint is not to be scanned, thereby significantly reducing a scanning area, shortening a scanning time, improving unlocking efficiency, fulfilling fast fingerprint unlocking, and reducing power consumption. A mobile terminal is also provided and includes a multiplexer configured to divide the sensor matrix into a plurality of blocks. Each of the blocks can independently perform fingerprint recognition scanning. When fingerprint unlocking is carried out, there is no need to scan an entire area of the sensor matrix, thereby improving unlocking efficiency and saving electric energy.
