摘要： A display device includes a display panel, a source driving part, a gate driving part, a readout part and a pulse generating part. The display panel includes an array substrate on which a source line and a gate line are formed, and an opposite substrate on which a common electrode is formed. The readout part is electrically connected with at least one of the lines of the array substrate and the common electrode of the opposite substrate, and reads out a detection signal during an elimination period of a frame period. The pulse generating part outputs a control pulse for driving the readout part during the elimination period. Accordingly, a detection signal is read out through lines or a common electrode that are/is formed for displaying an image, so that an aperture ratio may be increased, and a manufacturing process thereof may be simplified.

摘要： An apparatus for setting a common voltage include a screen generator, a flicker measuring part, a main controller and a read-only memory (“ROM”) programming part. The screen generator generates image data of a test screen. The flicker measuring part measures flicker on the test screen displayed on a display panel to which a common voltage corresponding to an estimated setting value is applied. The main controller calculates a measured flicker index from the measured flicker and compares the measured flicker index with a predetermined threshold value to determine a setting value corresponding to a flicker index of a plurality of calculated flicker indexes that is less than the threshold value. The ROM programming part writes the determined setting value to a ROM of a display module. Therefore, a common voltage is reestablished by the setting value, thus preventing flicker due to process variations.

摘要： A display panel includes a lower substrate, an upper substrate and a liquid crystal layer interposed therebetween. The lower substrate is divided into a display region for displaying an image and an adjacent peripheral region, and includes a plurality of pixel parts, a plurality of photo sensing parts, and a reflection preventing layer. The pixel parts are disposed in the display region for forming an image. The photo sensing parts are disposed in the display region for detecting the location of an object placed on or immediately adjacent to a surface of the display panel. The upper substrate faces the lower substrate, and includes a black matrix corresponding to the peripheral region. The reflection preventing layer is disposed in the peripheral region to prevent the black matrix from reflecting light back onto the photo sensing parts and thereby adversely affecting their operation.

摘要： An apparatus for driving a display panel includes a timing control part, a line memory part, a frame memory part and an image compensation part. The timing control part receives a horizontal synchronizing signal from an external system via a CPU interface process. The line memory part stores an image signal of an n-th frame in a line unit, based on the horizontal synchronizing signal. The frame memory part stores an image signal of an (n-1)-th frame based on the horizontal synchronizing signal. The image compensation part generates a compensated image signal of the n-th frame using the image signals of the n-th and (n-1)-th frames, which are respectively outputted from the line memory part and the frame memory part, based on the horizontal synchronizing signal. Accordingly, display quality in a CPU interface mode may be enhanced.
