Abstract: A display device includes a lighting device, a display panel, a memory, and a correction circuit. The lighting device includes a light exit area defined into light exit sections corresponding to light sources. The display panel includes a display area disposed opposite the light exit area and including pixels. The memory stores data of pixel matrix linked to the display sections. The memory stores position data of the pixels that are not disposed opposite the corresponding light exit sections and deviation data when a position error is caused between the light exit area and the display area. The correction circuit is configured to determine whether the memory stores the position data of the pixels and link new pixel matrix units to the corresponding display sections based on the deviation data if a determination result is affirmative.

Abstract: A display device includes a control circuit. By setting an intermediate point between a start point and an end point of a lighting period as a start point of the lighting cycle, and setting an intermediate point between a start point and an end point of a lighting period of the next lighting period as an end point of the lighting cycle, the control circuit controls a backlight such that an absolute value of a difference value between a first ratio of a sum of a length of a first lighting period in the first lighting cycle and a length of the next second lighting period in the first lighting cycle to a length of the first lighting cycle and the target duty ratio is 0.1 or less.

Abstract: A display device includes a lighting device, a display panel, a memory, and a correction circuit. The lighting device includes a light exit area defined into light exit sections corresponding to light sources. The display panel includes a display area opposed to the light exit area and including pixels. The display area includes display sections to be opposed to the light exit sections. The memory stores data of pixel matrix linked to the display sections. The memory stores position data of the pixels that are not opposed to the corresponding light exit sections and deviation data when a position error is caused between the light exit area and the display area. The correction circuit is configured to determine whether the memory stores the position data of the pixels and link new pixel matrix units to the corresponding display sections based on the deviation data if determination result is affirmative.

Abstract: A liquid crystal display device including a display unit, a backlight including a plurality of light sources, an LED control circuit configured to output a PWM signal (LED control signal) based on a display synchronization signal, such that the light sources are intermittently lighted, and an LED driver configured to control a drive current that is supplied to the light sources, based on the PWM signal, is provided with a monitoring control unit that is configured to perform monitoring at least one of the PWM signal, the drive current, and the display synchronization signal, as a monitoring target. When an abnormality of the monitoring target is detected, the monitoring control unit controls a waveform of the PWM signal such that the drive current that is supplied to the light sources in the backlight becomes zero.

Abstract: In a liquid crystal display device performing an overdrive drive of a liquid crystal panel and an impulse drive of a backlight, the liquid crystal panel includes an overdrive unnecessary area including pixels of which gradations converge to target levels before a backlight turn-on period when an arbitrary video signal is written to the pixels, and an overdrive necessary area including remaining pixels. An overdrive processing circuit includes a previous frame memory for storing an input video signal of less than one frame, including the input video signal with respect to the pixels in the overdrive necessary area, and a processing section for performing a correction for emphasizing a temporal change of a gradation, at least on the input video signal with respect to the pixels in the overdrive necessary area. With this, a capacity of a frame memory for storing a video signal of a previous frame is reduced.
