摘要： A light emitting display device and a driving method thereof are provided to display a normal image even when a display panel is rotated by 180 degrees, and to reduce the number of transistors by reducing the number of shift resistor of a scan driver. Plural first scan lines(S11~S16) are formed in plural rows, respectively. Plural second scan lines(S21~S26) are formed in the rows, respectively. A bi-directional shift register(210) shifts a first signal by a first period in a first direction in response to a first signal and outputs plural shift signals. The bi-directional shift register shifts the first signal by the first period in a second direction in response to a second signal and outputs plural shift signals. A first driver generates first select signals for respective first scan lines based on two of the shift signals and a first sub-clock signal. A second driver generates second select signals for respective second scan lines based on two of the shift signals and a second sub-clock signal, which is shifted from the first sub-clock signal by a second period. A select signal applying unit(220) applies one of the first and second select signals to a first scan line in a first row and a second scan line in a second row in response to a third signal. The select signal applying unit applies one of the select signals to a second scan line on the first row and a first scan line on the second row in response to a fourth control signal.

摘要： A driving apparatus and method of a liquid crystal display are provided to prevent degradation of image quality due to noise by discriminating and eliminating the noise in the vertical and horizontal synchronization signals, using the number of clocks input to the liquid crystal display. A counter(210) counts the number of clocks input in a blank period of a vertical synchronization signal and a horizontal synchronization signal. The counter is reset by a reset unit(220). A latch unit(230) latches the counted number of the clocks and, at the same time, latches the vertical synchronization signal and the horizontal synchronization signal. A control unit(240) compares the latched number of the clocks with the number of reference clocks and controls the output of the latched vertical synchronization signal and horizontal synchronization signal in accordance with the comparison result. The latch unit is reset by a latch reset unit(260).

摘要： An after image preventing circuit and method of a liquid crystal display are provided to enable a user to feel like a fixed image being displayed, while moving a part of the image in upper, lower, right and left directions at a predetermined time interval. A frame memory(121) stores image data of the previous frame. A comparator(122) compares the image data of the previous frame with image data of the present frame, and outputs a count signal if the data are identical with each other and a reset signal if not. A counter(123) starts counting in response to the count signal and generates a shift signal when the present count value reaches a predetermined reference value. An image shifting unit(124) shifts the image displayed at a liquid crystal panel in accordance with the shift signal.
