Abstract

Disclosed is an image display device using the field sequential method and capable of more efficiently suppressing occurrence of color breakup. One frame period is configured from single-color lighting subframes and an extended subframe in which a multicolor light source can assume arbitrary states. A color breakup intensity calculation unit (462) calculates for each mixed color component a color breakup intensity representing susceptibility to color breakup. A light source control signal generation / output unit (464) controls the light sources such that the greater the color breakup intensity of the mixed color component with the greatest color breakup intensity, the greater the amount of said mixed-color component is included in the light emitted from a light source unit in the extended subframe. Here, when an arbitrary mixed color component is set as a target component, if there is a first pixel region to be displayed which contains the target component, then the greater the size of the target component in the first pixel region, the greater the color breakup intensity for that target component.

Description

technical field

[0001] The present invention relates to an image display device and an image display method, and more specifically, to a technique for suppressing occurrence of color breakup in an image display device using a field sequential method. Background technique

[0002] Many liquid crystal display devices that perform color display include color filters that transmit red (R), green (G), and blue (B) light for each sub-pixel obtained by dividing one pixel into three. However, about 2 / 3 of the light irradiated to the backlight of the liquid crystal panel is absorbed by the color filter, so the liquid crystal display device of the color filter method has a problem of low light utilization efficiency. Therefore, a field sequential liquid crystal display device that performs color display without using a color filter has attracted attention.

[0003] In the field sequential method, a display period of one screen (one frame period) is divided into three subframes. In a...
