Display device with sensing element

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,
