A display panel includes an array substrate, an opposite substrate and a liquid crystal layer disposed between the array substrate and the opposite substrate. A sensing array outputs an initial voltage in response to an initial thickness of the liquid crystal layer during an initializing time and a sensing voltage in response to a varied thickness of the liquid crystal layer due to external force during a sensing time. A control part compares the sensing voltage with the initial voltage, determines whether the external force is applied to the display panel, and generates information indicating a position to which the external force is applied. Thus, the display apparatus may improve sensing ability to an external signal inputted through the display panel thereof.

A display device includes: a plurality of sensing data lines; a plurality of sensing units that output sensing signals through the plurality of sensing data lines; a signal selector that selects one sensing signal among the plurality of sensing signals; an automatic voltage adjusting unit that, when one sensing signal is selected by the signal selector, performs a controlling operation so as to allow a magnitude of the selected sensing signal to be in a predetermined range; and a voltage generator that adjusts the magnitude of the voltage applied to the sensing data lines based on a control signal output from the automatic voltage adjusting unit. According to the voltage adjusting operation, the sensing signal output through the sensing data line is always in an appropriate range. As a result, the touch determining operation on the sensing units can be accurately performed, so that it is possible to improve reliability of the sensing units.

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.
