Image display apparatus with image entry function

摘要

An image display apparatus with image entry function capable of high-speed and high-accuracy direct screen entry without increasing the peripheral circuit scale or the number of circuit elements for each pixel that lower the pixel aperture ratio. A first pixel circuit and a second pixel circuit are alternately arrayed horizontally. First and second data lines are connected to a data driver and a sensor signal processor circuit. Selector switches are connected to the input terminal of the data driver. Gray scale voltages are sent from the data driver to the first and second data lines, and first and second photo sensor signals are sent to the sensor signal processor circuit.
