LIQUID CRYSTAL DISPLAY DEVICE INJECTING LIQUID CRYSTAL WITH DIFFERENT CHARACTERISTIC TO AN UPPER REGION, A MIDDLE REGION, AND A LOWER REGION OF THE LIQUID CRYSTAL DISPLAY PANEL

摘要

PURPOSE: A liquid crystal display device is provided to improve display quality by improving motion blur locally generated in the upper and lower regions of the liquid crystal display panel.;CONSTITUTION: A data modulation unit matches the synchronization of a liquid crystal driving signal of the liquid crystal display panel and a backlight driving signal of the backlight unit. A frame memory(141) stores the data of a previous frame. A first lookup table(143) generates the compensated second data signal by comparing the first data signal of the current frame with the data signal of the previous frame stored in the frame memory. A second lookup table(145) generates the second data signal compensated with the larger gradation than the compensated data signal of the first lookup table. A multiplexer selects the first data signal, the second data signal, and the third data signal according to the regions of the liquid crystal display panel and supplies the selected signal to the data driver.;COPYRIGHT KIPO 2010
