Abstract
A display device and an operating method of the display device are disclosed. The display device includes a display element having a front side and a back side; an optical filter through which a light signal having a wavelength greater than 800 nm travels from the front side to the back side of the display element; an optical detector receiving a portion of the light signal traveling from the front side to the back side of the display element, the optical detector including a first substrate formed of a first material; a detection region supported by the first substrate, wherein the detection region is formed of a second material different from the first material; and a detector control circuit electrically coupled to the optical detector, wherein the optical detector is positioned such that the portion of the light signal traveling from the front side to the back side of the display element passes through (i) the first substrate of the optical detector; or (ii) the detector control circuit before entering the detection region of the optical detector.
