摘要： 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.

摘要： 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.

摘要： A gate driving circuit includes a shift resister having stages cascade-connected to one another. Each stage includes a pull-up part, a first pull-up driving part, a first pull-down part and a first ripple prevention part. The pull-up part outputs a high value of a first clock signal to a first output terminal. The first pull-up driving part applies a low value to a control electrode of the pull-up part to turn off the pull-up part. The first pull-down part applies the low value to the signal outputted to the first output terminal. The first ripple prevention part applies the low value of the first input signal to the control electrode of the pull-up part to turn off the pull-up part, and prevents ripple from occurring at the control electrode of the pull-up part. Thus, an abnormal gate-on signal is prevented, to reduce driving malfunction of a display apparatus.
