Abstract

In a light sensing element having simplified structure, an array substrate having the light sensing element and an LCD apparatus having the light sensing element, the light sensing element includes a first electrode, a control electrode and a second electrode. An alternating bias voltage is applied to the first electrode. An off voltage is applied to the control electrode. The second electrode outputs a light-induced leakage current based on an externally provided light and the bias voltage. Therefore, the array substrate includes one light sensing switching element corresponding to one pixel so that structure of the array substrate is simplified and opening ratio is increased.
