Liquid crystal display device having image sensing function |
摘要 |
A liquid crystal display device includes a gate line and a data line intersecting each other on a substrate. The liquid crystal display device further includes a photo sensing device and a first thin film transistor ("TFT") located at an intersection area of the gate line. The photo sensing device operates to sense an ambient light and includes a storage capacitor to store charge generated by light. The photo sensing device is drive by a driving voltage other than the data voltage.
