摘要： Provided are a source driver and a source line driving method using a gamma driving scheme for a liquid crystal display (LCD) device. The source driver for driving the LCD device encodes serially input red (R), green (G), and blue (B) digital image data during a horizontal scan period, stores the encoded values of the R, G, and B digital image data in a first memory, and turns on or off grayscale voltage amplifiers included in a gamma voltage amplifying unit according to the encoded values stored in the first memory. Accordingly, when an output selecting unit selects a corresponding grayscale voltage output from the gamma voltage amplifying unit, and outputs the selected voltage to each source line, only the amplifiers necessary for driving a liquid crystal panel are turned on.

摘要： A source driver control device and method. The source driver control device includes a memory, a first write controller, a second write controller and a write clock signal generator. The memory receives display data corresponding to an image and stores the display data in response to a write clock signal. The first write controller generates a first write enable signal in response to a vertical back porch and a horizontal back porch. The second write controller generates a second write enable signal, which is enabled for each write cycle of storing the display data in the memory, in response to the first write enable signal. The write clock signal generator generates the write clock signal in a period in which the second write enable signal is enabled. The write cycle corresponds to a multiple of a reference write cycle. The source driver control device and method can reduce power consumed when the display data is written in the memory.

摘要： In a gamma correction digital-to-analog converter, one of first gamma correction reference voltage signals is selected as a first corresponding gray scale signal based on lower m+n bits of a k bit digital input signal when upper l bits of the k bit input signal correspond to an upper or lower code set, where k=l+m+n, and where k, l, m and n are integers. A pair of adjacent second gamma correction reference voltage signals is selected from second gamma correction reference voltage signals based on upper l+m bits when the upper l bits correspond to a middle code set, and one is selected from the pair of second gamma correction reference voltage signals and 2n−1 divided signals as a second corresponding gray scale signal, the divided signals being obtained by dividing an interval between the selected pair into 2n levels. The first or second gray scale signal is selected to be output.
