The display device of an embodiment of the present invention includes a display section which includes a pixel having a plurality of sub pixels and displays an image whose luminance is based on a luminance gradation of an inputted display signal, wherein the display section is arranged so that an integral value obtained by carrying out the following steps (a) to (d) is not more than 0.0202, the step (a) of measuring surface luminance of the display section and oblique luminance of the display section viewed at 60&#xb0; from a front direction of the display section, the step (b) of standardizing the front luminance and the oblique luminance so as to calculate front standardized brightness x and oblique standardized brightness, the step (c) of determining n of x^(n/2.2) so that an integral value of a difference between x^(n/2.2) and the front standardized brightness x is equal to an integral value of a difference between the oblique standardized brightness and the front standardized brightness x, the step (d) of integrating an absolute value of a difference between x^(n/2.2) and the oblique standardized brightness, from minimum luminance to maximum luminance of the front standardized brightness x, so as to obtain an integral value.

In one embodiment of the present invention, to time-divide one frame of an input image signal into a first-half sub frame and a second-half sub frame, the grayscale of the signal in the second-half sub frame is set at a grayscale for dark display and the grayscale of the display signal of the first-half sub frame is adjusted, when the input image signal indicates low brightness. When an image with high brightness is displayed, the grayscale of the display signal of the first-half sub frame is set at a second predetermined value smaller than the maximum value and the grayscale of the display signal of the second-half sub frame is adjusted. Thereafter, in accordance with a combination of the input image signals of the (N-1)-th frame and the N-th frame, overshoot is performed with respect to the display signal of the first-half sub frame.

Driving control apparatus of display apparatus, display method, display apparatus, display monitor, and television receiver

A liquid crystal display system of the present invention includes: an operation processing apparatus having a digital-analog converter converting a digital video signal to an analog video signal based on predetermined time information and a synchronization combining circuit superimposing the predetermined time information on at least one of a horizontal synchronizing signal and a vertical synchronizing signal; and a liquid crystal display apparatus converting the analog video signal to a digital video signal based on the predetermined time information, thereby displaying an image based on the converted digital video signal.

Liquid crystal display system using a digital-to-analog converter

To display a more natural display screen without sense of strangeness, when displaying a video signal having a greater number of horizontal scanning lines than the number of horizontal display lines of the display means. The video signal is displayed by thinning at a rate of one out of every plurality of video signal groups. Accordingly, missing of only upper and lower portions of the video signals of the display screen is prevented, and when the video signal is compressed and displayed, a natural display screen without sense of strangeness is presented.
