发明名称 Liquid crystal display device for display with gray levels
摘要 A liquid crystal display device has an arrangement of a plurality of pixel display regions each including a plurality of divided pixels, and is capable of effecting display with a large number of gray levels. Each of the divided pixels is displayed individually and selectively with at least two gray levels. The liquid crystal device further includes pixel electrodes for individually and selectively enabling the divided pixels, and a gray level setting circuit for controlling the sum of the areas of the enabled divided pixels, thereby setting the gray levels of the pixels. In this device, one pixel display region includes n divided pixels and if each pixel can be displayed with m gray levels, the areas of the pixels are set to form a geometric progression using m as a common ratio, whereby display with mn gray levels for one display region can be effected with high precision.
