摘要:
A driving method of a liquid crystal display is provided for improving an echo phenomenon in the screen and improving crosstalk in a 3D display device. The liquid crystal display includes a liquid crystal panel and a light source unit divided into a plurality of blocks and that irradiates light by a light source unit of the corresponding block being driven at a response time of liquid crystals of the liquid crystal panel. Data of a liquid crystal panel corresponding to the plurality of blocks is analyzed to determine an n-th block corresponding to a portion having the highest visibility. Driving periods of light source units of the n-th block, an (n−1)-th block, and an (n+1)-th block are synchronized.

A data processing method compensates a color of input data for a present frame of a display panel of a display apparatus to generate color compensating data. Dimming levels of a plurality of light emitting blocks included in a light source module for the display panel are determined using the color compensating data. Compensating data of the present frame is generated using the color compensating data and compensating coefficient data including the dimming levels.

A method of driving a light source comprises gradually decreasing a luminance of a light emitted from an upper light emitting module disposed along a first side of a display panel during a frame where the first side corresponds to a start point of a scanning direction; and gradually increasing a luminance of a light emitted from a lower light emitting module disposed along a second side of the display panel during the frame where the second side corresponds to an end point of the scanning direction.

A method of displaying an image, the method includes providing a source data frame and at least one copy data frame repeating the source data frame to a display panel and, selectively providing boosted light of a first luminance level to the display panel during a first period and normal light of a second luminance level to the display panel during a second period, based on the source data frame and the copy data frame, the second luminance level being smaller than the first luminance level, the second period being longer than the first period.
摘要:
A liquid crystal display includes a liquid crystal display panel which displays an image in response to a gate signal and a data signal, a panel driving circuit which provides the gate signal and the data signal to the liquid crystal display panel in response to a control signal, a backlight unit including n light generating blocks which provide light to the liquid crystal display panel, and a backlight control unit which turns each of the n light generating blocks on and off i times during one frame period. Each of the n light generating blocks has a different duty ratio for each of i turn-on periods when the n light generating blocks are turned on in the one frame period, and ‘n’ and ‘i’ are integers greater than or equal to two (2).
