    Abstract: A display panel includes a plurality of pixels; a plurality of detection units formed in row and column directions that generate an element output signal when the display panel is touched; a detection signal processor that generates detection data based on the element output signal; and a touch determination unit that classifies the detection data in a row or column direction, that converts a row or column coordinate of a touch position or sustains a previous coordinate by comparing a reference value of each direction with the detection data, and that determines whether the touch has occurred according to the conversion number of the row or column coordinate. When the screen is continuously touched along a row or column direction, the touch or lack thereof and its position can be accurately determined by using the previous touch position information as current touch position information.

    Abstract: In a light sensor test unit, a test circuit is built in a display panel and connected to an output node of a light sensor which senses an intensity of an external light. When external light having a predetermined intensity is provided to the light sensor, the test circuit outputs a driving signal in response to a sensing signal output from the output node. A test pixel part includes pixels selected from a plurality of pixels arranged in the display panel and receives the driving signal from the test circuit to display a gray-scale corresponding to the driving signal. A brightness measurer measures a brightness corresponding to the gray-scale displayed in the test pixel part to compare the measured brightness with a predetermined brightness, thereby testing whether the light sensor built in the display panel is normally operated.
