Abstract: An image display device includes a display panel having a plurality of pixels, and a photoresistor pattern formed in a non-light emitting area between the plurality of pixels; a panel driving controller to drive light-emission control lines of the display panel; and a bio-signal detector that detects an output voltage of the photoresistor pattern which resistance is variable based on light reflected from the target object, and detects a bio-signal of the target object based on the detected output voltage, thereby, detecting the bio-signal of the target object using the image display light from the display panel may allow efficiently detecting the bio-signal without a separate light source or light source operation circuit for detecting the bio-signal.

Abstract: A touch screen driver and method for driving the same are disclosed. The touch screen driver includes a Tx driving circuit which sequentially supplies a pair of out-of-phase composed of a first driving signal and a second driving signal which has a phase difference of 180° with respect to the first driving signal and the second driving signal driving signals to Tx lines, wherein the first signal and the second signal are simultaneously supplied to the adjacent Tx lines, respectively; and an Rx driving circuit which samples a charge of the touch sensor received through the Rx lines coupled with the Tx lines and converts the sampled charge into digital data.
