Abstract: A display panel and a display device thereof are provided. The display panel comprises a display module comprising a first substrate and a first polarizer, wherein a light-exiting surface of the display module is arranged on an outer side of the first polarizer; a fingerprint recognition module disposed on an outer side of the first substrate and comprising a fingerprint recognition layer and a second polarizer disposed on an inner side of the fingerprint recognition layer; and a light source disposed on an inner side of the first polarizer. The fingerprint recognition layer recognizes fingerprint based on fingerprint signal light. The first polarizer is engaged with the second polarizer, such that the fingerprint signal light is transmitted through the first polarizer and the second polarizer without a light intensity loss, and the second polarizer reduces the light intensity of fingerprint noise light.

Abstract: An array substrate and a method for fabricating the array substrate, a display device and a method for driving the display device are provided. The array substrate includes: a substrate having a first surface and a second surface; a touch control signal driving line disposed on the first surface; an isolation layer disposed on the first surface and covering the touch control signal driving line; a via hole formed in the isolation layer; and a gate line disposed on the isolation layer and electrically connected to the touch control signal driving line through the via hole. The scanning time of the array substrate is not reduced due to a touch control detection, and the undercharge of pixels is thus avoided.
