Abstract: A Gamma curve correction method for an LCD sets a ground potential of the LCD as a common voltage, and adjusts at least one of a plurality of positive Gamma voltages and a plurality of negative Gamma voltages of the LCD such that the central value of a Gamma curve established by the positive Gamma voltages and the negative Gamma voltages becomes closer to the common voltage. As a result, flickers existing in the images of the LCD are improved.

Abstract translation: 用于LCD的伽马曲线校正方法将LCD的接地电位设置为公共电压，并且调整LCD的多个正伽马电压和多个负伽马电压中的至少一个，使得伽马的中心值 由正伽马电压和负伽马电压建立的曲线变得更接近于公共电压。 结果，存在于LCD的图像中的闪烁被改善。
