1. A display device with sensing element, comprising:
a substrate having a disposing surface;
a plurality of display elements, disposed above the disposing surface to present an image;
at least one sensing element disposed above the disposing surface to sense light brightness of light projected toward either side of the substrate; and
at least one light adjustment element in signal-transmittable connection with the display elements and the at least one sensing element, with the at least one light adjustment element calculating an image compensation value according to the light brightness to adjust a plurality of control signals inputted into the display elements for matching a value calculated from equation (1) to a default ratio, to determine a contrast of the image,

OG Complex Work Unit Math
wherein LENV is the light brightness sensed by the at least one sensing element; LDIS1 is a first brightness corresponding to the control signals; LDIS2 is a second brightness corresponding to the control signals; LDISR is a brightness corresponding to the light of the light brightness reflected from the display device, wherein the first brightness is higher than the second brightness.
