Abstract
An image display system includes a light pen to generate light to input data, and a display panel to display images in response to the light provided from the light pen. The display panel includes a first substrate on which pixel electrodes are formed, a second substrate on which a common electrode are formed, and a photo-sensor formed on the first substrate. The photo-sensor detects the light provided from the light pen to generate a light detect signal. The image display system also includes a driving module to provide new image data to the display panel to display new images in response to the light detect signal from the photo-sensor.
