Abstract

A flat panel has a plurality of pixel areas each having a light emitting area, a light transmitting area, and a light sensing area in the light emitting area. The flat panel includes a first support board; a sensing array on the first support board and having a light sensing element corresponding to the light sensing area of each of the pixel areas; a micro lens between the first support board and the light sensing element; a first light shielding wall between the first support board and the light sensing element to correspond to an edge of the light sensing area of each of pixel areas; a light emitting array on the sensing array and having a light emitting element corresponding to the light emitting area of each of the pixel areas; and a second support board on the light emitting array facing the first support board.
