Method and apparatus for a liquid crystal display (LCD) having an input function |
摘要 |
A method and an appartus for a liquid crystal display (LCD) having an input function are provided. A first transistor is provided in each of the pixel cells of a pixel cell array of a LCD. This first transistor, or display transistor, is a thin film transistor (TFT) switch that is coupled to a transparent electrode that controls the display of pixels on the LCD. Moreover, a second transistor is provided in each of the pixel cells of the pixel cell array. This second transistor is a TFT switch that forms part of a metal-oxide semiconductor (MOS) image sensor array including a photo diode and a micro lens. The second transistor causes an input to be sensed by the LCD. The inputs sensed by the LCD include image inputs and inputs from a pen and a human touch. The first and second transistors are fabricated on the same side of the same substrate.
