摘要： A light guide plate includes a light-emitting surface, a light-reflecting surface opposed to the light-emitting surface, and a light-incident surface including a protrusion formed continuously along an edge portion of the light-emitting surface. Accordingly, light that has entered the protrusion is transmitted through the protrusion and totally reflected on an inner surface of the light-emitting surface to thus propagate inside the light guide plate. As described above, since incident light components emitted toward an upper portion of the light-incident surface can be effectively blocked by the protrusion, luminance distribution characteristics as well as a light use efficiency can be improved. The light guide plate is produced by a punching press process.

摘要： In a display device and a display driver, when a grayscale of a display image is equal to or lower than a specific grayscale value obtained from a histogram of the display image, a display grayscale is extended with a linear function. On the other hand, when a grayscale of a display image is equal to or higher than the specific grayscale value, histogram equalization of a part higher than the specific grayscale value is performed, and the display grayscale is extended with a non-linear function obtained from the histogram equalization.

摘要： A processing portion for conversion from RGB to RGBW includes a W generating circuit, a sub-pixel rendering circuit, a W intensity calculating portion which transmits a W intensity setting value to a W generating circuit, and a low power backlight control circuit which expands data on the basis of the RGBW pixels generated by the sub-pixel rendering portion and lowers the backlight in accordance with the amount by which the data is expanded. The inputted RGB data is used as the RGBW data with the W intensity calculated by the W intensity calculating portion. A backlight control signal is generated based on the amount of data expansion in the sub-pixel rendering portion. Deterioration (darkness) of image quality due to a reduction in the brightness of a single color as a result of the conversion from RGB pixels to RGBW pixels is prevented and a reduction in the power is achieved.

The expansion coefficients of saturation data are decided based on the initial and user target color gamut apex coordinates, and saturations of display data are expanded according to the expansion coefficients. Thus, the degree of expanding the saturations can be controlled for each color gamut or each of R, G and B color properties of an LC display panel.
