Abstract

A display driver panel device and a method therefor are disclosed. The device includes: an image sensor array consisting of pixel sensor elements arranged in M rows and N columns; and a display driver array consisting of display driver elements arranged in M rows and N columns. Each of the display driver elements corresponds to a respective one of the pixel sensor elements. As such, first display input signals generated by the pixel sensor elements from a received external imaging radiation can be sent to the respective corresponding display driver elements. As a result, the display driver elements respond at the same time, resulting in an increased response speed of the display driver panel device.
