Patent ID: 7773078

Claim:
An information detection display device comprising: light sensing units disposed in areas defined by image scanning lines and image data lines on a first substrate and being disposed under pixel electrodes, the light sensing units being operative to generate a current in an amount which is a function of an amount of light impacting the light sensing units and output sensor data signals based on the current; a sensor scanning driver providing sensor scanning signals; sensor scanning line disposed on the first substrate, and coupled to the sensor scanning driver for receiving sensor scanning signals from the sensor scanning driver and controlling the output of the sensor data signals from the light sensing units; a sensing signal processor; at least three sensor data line disposed on the first substrate, each of the at least three sensor data lines coupled to one of the light sensing units so as to form a set of at lest three light sensing units, and the at lest three sensor data lines being coupled to each other, wherein the at lest three light sensing unit comprise a first light sensing unit disposed under at least one red color filter stripe, a second light sensing unit disposed under at least one green color filter stripe, and a third light sensing unit disposed under at least one blue color filter stripe to receive sensor data signals and transmit the sensor data signals to the sensing signal processor.
