摘要： A liquid crystal data calculation section forms, on the basis of input image data, liquid crystal data to display an image on a liquid crystal panel. In at least one example embodiment, an LED data calculation section forms, on the basis of the input image data, LED data for adjusting an amount of light of an LED backlight. An LED control section controls an amount of an output current of an LED power source on the basis of the LED data, and includes a protection function of limiting the amount of the output current so that the amount of the output current does not exceed a predetermined upper limit. In a case where the amount of the output current of the LED power source is reduced to the upper limit by the LED control section, a liquid crystal transmittance correction section corrects the liquid crystal data and increases transmittance so as to compensate reduction in luminance of the backlight.

摘要： A multiple primary color display device (100) includes a plurality of pixels (P) located in a matrix including a plurality of rows and a plurality of columns. The plurality of pixels are each formed of a plurality of sub pixels including at least four sub pixel for displaying different primary colors from one another. The multiple primary color display device can sort the plurality of sub pixels which form each of the pixels into n number of virtual pixels (n is an integer of 2 or greater), each of which is formed of two or more sub pixels, and use each of the n number of virtual pixels as a minimum color display unit for providing display. The two or more sub pixels which form each of the n number of virtual pixels include a sub pixel common to another of the n number of virtual pixels. When a line having a width corresponding to the n number of virtual pixels is displayed, two sub pixels which are located at both of two ends, in a width direction, of the line and which display a certain identical primary color to each other have a luminance lower than the luminance that the two sub pixels originally have.
