Title
(EN) LIQUID CRYSTAL PANEL AND DRIVING METHOD THEREOF
Abstract
(EN)

A driving method of liquid crystal panel includes: providing a liquid crystal panel including multiple pixel units, each pixel unit at least including a green sub-pixel and a blue sub-pixel; dividing the liquid crystal panel into multiple display units, each display nit including neighboring first pixel unit and second pixel unit; and for grayscale values B and G of blue sub-pixel and green sub-pixel required by the display unit, dividing the grayscale values B and G respectively into a combination of grayscale values BH, BL and a combination of grayscale values GH, GL for the first and second pixel units, so that brightnesses of the blue sub-pixels and the green sub-pixels of the display unit at an oblique viewing angle are approximate to a predetermined Gamma(γ) curve. γ=1.8˜2.4. Moreover, a liquid crystal panel being driven by the above driving method also is provided.
