Abstract:
1. A liquid crystal display device comprising: a liquid crystal display panel including a plurality of pixels and a plurality of sensing parts, each of the sensing parts having a light-sensitive switching device which is directly responsive to light and each of the sensing parts generating an analog signal including a location information in response to an incident light, the location information indicating a location where the light enters; and a control part receiving the analog signal and transforming the analog signal into a digital signal, the liquid crystal display device being controlled in response to the digital signal, wherein each of the pixels includes a first switching device and a pixel electrode electrically connected to the first switching device, wherein the first switching device includes a gate electrode electrically connected to a gate line, a source electrode electrically connected to a data line and a drain electrode electrically connected to the pixel electrode so that a data signal is provided to the pixel electrode through the data line and the source electrode, wherein the light-sensitive switching device is a second switching device electrically connected to receive a first analog signal from the data line and is turned on in response to the incident light to output the first analog signal to a third switching device outputting the first analog signal in response to a second analog signal applied to the gate line, and wherein each of the sensing parts further comprises a first sensor line receiving the first analog signal from the third switching device and transmitting the first analog signal to the control part, wherein the first sensor line is electrically insulated from the data line and directly connected to the third switching device.
