20100309107DISPLAY DEVICE - It is an object of the present invention to provide a liquid crystal display device with high color reproduction ability even when an area active backlight is driven. A liquid crystal display device (12-09-2010
20100321414DISPLAY DEVICE - It is an object of the present invention to provide a display device that can improve the color reproductivity on a displayed image and improve the display quality. A liquid crystal display device (12-23-2010
20110007104LIGHTING DEVICE AND DISPLAY DEVICE HAVING THE SAME - There is provided a lighting device that can reduce the occurrence of both color irregularity and brightness irregularity of light to be irradiated onto an irradiation surface even if one of a plurality of light-emitting elements included in light sources fails to light properly, and a display device using this lighting device. The lighting device includes a plurality of light sources (01-13-2011
20110090265IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD - There is provided an image display device capable of suppressing the occurrence of a color shift while ensuring a sufficient color reproduction range. An in-area maximum luminance obtaining unit (04-21-2011
20110115826IMAGE DISPLAY DEVICE - An area active drive processing unit (05-19-2011
20110181793LIGHT EMITTING DEVICE FOR IMAGE DISPLAY, DISPLAY DEVICE AND TELEVISION RECEIVER - A light emitting device for image display includes an LED current setting circuit and an LED voltage setting circuit. In at least one embodiment, the LED current setting circuit generates a current control signal to vary an element current flowing in the LED element depending on an image display mode. The LED voltage setting circuit generates a voltage control signal to vary driving voltage driving the LED element depending on the image display mode. The light emitting device further includes a voltage generation circuit that generates the driving voltage according to the voltage control signal and the driving voltage to the LED element.07-28-2011
20110193889Backlight unit, liquid crystal display device, data generating method, data generating program and recording medium - Provided are a backlight unit and a liquid crystal display device including the backlight unit mounted therein. In at least one embodiment of the backlight unit, a process control section performs correction processing to a light source red image signal of a red LED chip, by using an LUT, based on the relationship between the light source red image signal and luminance of the red LED chip. Furthermore, correction processing is performed by using an LUT, based on a light source green image signal of a green LED chip different from the red LED chip. The light source red image signal becomes a new light source red image signal. In the backlight unit, luminance nonuniformity and chromaticity nonuniformity due to the fact that one LED chip is affected by instantaneous heat generated by other LED chip are reduced.08-11-2011
