ABSTRACT:
A liquid crystal display unit includes a liquid crystal panel having a plurality of liquid crystal pixels and a plurality of switching elements provided in correspondence to the respective pixels. A back light disposed at the back of the liquid crystal panel and guides red, green, and blue light to the surface thereof; an image memory for storing pixel data PD to be displayed on the respective pixels; an inverted data generating circuit for generating inverted pixel data #PD of the respective pixel data PD; and a control signal generating circuit and a data driver wherein first scanning for writing the pixel data PD with respect to individual pixels of the liquid crystal panel during each period in which red, green, and blue light are emitted in time-sharing manner, and second scanning for writing the inverted pixel data #PD with respect thereto are carried out in this order. Such problems that crosstalk occurs easily, besides response speed thereof is comparatively slow, so that it is not suitable for display of moving picture despite manufacturing cost of STN type display unit is comparatively inexpensive, while because TFT-TN type display unit requires a highly luminous back light, its power consumption is high, viewing angle is narrow, adjustment is difficult in color balance and the like are solved.
