The present invention provides a display panel and its application, the display panel comprises a first substrate, a second substrate, a liquid crystal layer disposed between the first substrate and the second substrate, an image sensing module disposed on the second substrate facing to a side of the first substrate, a driving module disposed on the second substrate facing to the side of the first substrate for driving a plurality of liquid crystal molecules distributed in the liquid crystal layer. Wherein, the liquid crystal molecules disposing between the image sensing module and the first substrate is configured to form a liquid crystal lens in response to a vertical electric field between the first and second substrates. The image sensing module is configured for receiving the image light focused by the liquid crystal lens.
