Abstract: The present disclosure provides a display device and a driving method thereof. A plurality of backlight partitions and a plurality of display partitions are arranged in a one-to-one correspondence, each backlight partition independently provides backlight for a corresponding display partition, and the backlight partition corresponding to each display partition is turned off in a scanning phase and a liquid crystal deflection phase, and is turned on in a light-emitting phase. While brightness requirements of a display device with high-resolution are met, a display effect of the display device is better.

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: The present invention provides a touch panel, comprising an array substrate, a touch receiving layer, a touch transmitting layer, a separation layer and a cover plate; the array substrate and the cover plate oppositely located; the touch receiving layer formed at one side of cover plate facing the array substrate, and the separation layer formed at one side of the touch receiving layer away from the cover plate, and the touch transmitting layer formed between the array substrate and the separation layer; a mutual capacitance formed between the touch receiving layer and the touch transmitting layer so that the separation layer can be compressed to change a capacitance value of the mutual capacitance to achieve recognition of a touch position. Embedded 3D touch sensors can be realized and the external pressure touch sensors are not required to be connected to decrease the complexity of the system.
