  • Patent number: 7956834
    Abstract: Provided are a method and apparatus for driving a liquid crystal display. The apparatus includes: a moving image detector which reads an input signal frame by frame and compares gray-scale data of a previous frame to gray-scale data of the current frame to detect a moving pattern; a gray-scale difference calculator which calculates a gray-scale difference in the detected pattern to discriminate the boundary of the pattern from the inside of the pattern; and an output processor that generates an over-driving voltage for over-driving pixels corresponding to the inside of the pattern and applies the over-driving voltage to pixels of liquid crystal.

  • Publication number: 20070109254
    Abstract: A liquid crystal display (LCD) and a method for driving the same are provided. The LCD includes a liquid crystal panel divided into a plurality of panel regions having data lines and gate lines arranged two-dimensionally; gate drivers that correspond to the panel regions, are independently driven, and alternately supply gate signals to the corresponding panel regions; a data driver supplying data signals to the data lines; and a backlight unit radiating light to the liquid crystal panel. Accordingly, color mixing can be substantially prevented by changing the transmission mode of gate signals.

  • Publication number: 20030201961
    Abstract: Disclosed are a projection system and method for a reflection-type liquid crystal display (LCD). The projection method of the reflection-type LCD includes the steps of selectively transmitting a beam in white light, sequentially converting the selectively transmitted beam into R/G/B light and dividing the converted light into an S-polarization beam and a P-polarization beam, a reflection-type LCD receiving the polarized beam and driving liquid crystal for each pixel to thus realize a screen and enlarging the thus realized image and projecting the enlarged image to the screen through a projection lens system, and applying a reset voltage to the reflection-type LCD and forcibly displaying an entire screen to be black before displaying the next screen when a screen is displayed.
