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： A touch position detecting method, a device using the method, and a touch screen display device having the device are disclosed. A touch sensing unit senses a touch event and outputs a sensing data. A reference update unit updates a reference data with an n-th frame sensing data provided from the touch sensing unit, based on a predetermined update signal. A position detecting unit detects the touch position by using the reference data and an (n+i)-th frame sensing data from the touch sensing unit. Therefore, the touch position is easily detected by determining a difference between the reference data and the sensing data at a certain time.

摘要： A shift register includes a plurality of stages each generating an output signal in sequence and including a buffering section, a driving section, a first charging section, and a charging control section. The buffering section receives one of a scan start signal and an output signal of a previous stage so that the driving section generates the output signal of a present stage. The first charging section includes a first terminal electrically connected to the driving section and a second terminal electrically connected to a first source voltage. The charging control section applies the output signal of a next stage to the first charging section. Therefore, a gradual failure of TFT is reduced.
