Liquid Crystal Display Device for having OCB mode and method for driving the sme

摘要

OCB liquid crystal a reset voltage to a high voltage for a liquid crystal cell of a bend transition discloses a liquid crystal display device and a driving method having the OCB mode is applied to the common electrode of the liquid crystal of the OCB liquid crystal cell. A liquid crystal display device having the OCB mode according to the present invention each frame is the initial or before data of each pixel by applying a voltage of the DC-DC converter to the common electrode to reset the liquid crystal of the OCB liquid crystal cell. In the case of sequential driving by dividing one frame into a red, green, and blue field each field before beginning to apply the voltage of the DC-DC converter to the common electrode to reset the liquid crystal of the OCB liquid crystal cell. The DC-DC converter is applied to the 15V to 30V to the common electrode. Light transmittance of the liquid crystal during the reset is 0 (black state). Thus, blurring (Blurring) have the effect of improving the luminance due to the shortening of the reset period at the same time as the removal of the effect. ; A liquid crystal display, a reset voltage, OCB liquid crystal
