A display apparatus includes: a display; a display driver that drives the display such that the display displays in accordance with display data; and a host controller that transfers update display data of one screen to the display driver. The display driver includes a light-emission controller that causes a self-luminous elements to emit light, and a memory that stores the update display data of the one screen. The display driver reads the update display data on the memory after an elapse of a predetermined period of time from a drive end time at which the display controller finishes driving in accordance with the update display data and drives the screen by using the read update display data. The display driver drives the self-luminous elements once or more at a timing when the update display data from the host controller to the display driver is not updated.

Display apparatus

A display device includes: a display unit; a display driver configured to drive the display unit; and a display-data generator configured to transfer a screenful of update display data to the display driver. The display driver includes a light-emission controller configured to control self-luminous elements to emit light, and a memory storing a screenful of the update display data. After a lapse of a predetermined time period from a driving stop time, the display driver reads the update display data stored in the memory and then uses the update display data to drive a screen, the driving stop time being a time when the display unit is stopped from driving based on the update display data. The display driver causes the self-luminous elements of the display unit to emit light, even during a display update or no display update performed on the display driver by the display-data generator.

Display device, method of display driving, and non-transitory computer-readable medium

The present invention relates to a light emitting device and achieves either desirable color reproduction or improved image quality of a moving image according to the usage of an electronic device. The electronic device includes a first light emitting device and a second light emitting device having color reproducibility lower than that of the first light emitting device and having a response speed faster than that of the first light emitting device, and a control device includes a light emission control section configured to control light emission of the first light emitting device and light emission of the second light emitting device according to a usage of the electronic device such that a relation between luminance of the first light emitting device and luminance of the second light emitting device satisfies a predetermined condition.

Control device, electronic device, and control method

The present invention relates to a light emitting device and achieves either a high luminance with low power consumption or an increased image quality of a moving image according to the usage of an electronic device. The electronic device includes a first light emitting device and a second light emitting device, and a control device includes a light emission control section configured to control light emission of the first light emitting device and light emission of the second light emitting device according to a usage of the electronic device such that a relation between luminance of the first light emitting device and luminance of the second light emitting device satisfies a predetermined condition.

Light emission control device, electronic device, and light emission control method

A display device includes control electronics and a pixellated liquid crystal (LC) panel. The control electronics receives inputs of main image data for a main image and side image data for a side image. The control electronics outputs combined image data combining the main and side images such that an on-axis viewer perceives from the combined image the main image, and an off-axis viewer perceives from the combined image the side image. The output image data comprises data values chosen from a set of available output data values for the pixels selected from multiple sets of available data values depending on at least on the side image data. For a pixel currently being processed, the output data value is chosen from the selected set of available output data values for which a resulting luminance value is closest to a target luminance value for the current pixel.

Included are: an image analyzing section () which determines whether an image is a still image or a moving image; an image processing section () which, in a case where the image analyzing section () determines that the image is the moving image, increases pixel values of respective pixels of a display screen from those before the image analyzing section () determines that the image is the moving image; and a BL control section () which lowers brightness of a backlight () from that before the image analyzing section () determines that the image is the moving image.

Control device and control device controlling method

The present invention includes a write-in start position control section () that performs a process of shifting, by a given shifting amount, a start position of a write-in operation to the frame memory (), when the write-in operation is started, the given shifting amount being predetermined so as not to exceed a capacity reserved in advance in the frame memory.

Memory control device, mobile terminal, and computer-readable recording medium

A control device executes a program including the steps of: when an unintended black image is detected, notifying a target value of brightness of a backlight and a correction amount of brightness of an image immediately before the black image is detected, until a predetermined time elapses; correcting the image based on the notified correction amount of the brightness of the image; causing a liquid crystal panel to display the corrected image; and controlling the backlight based on the notified target value of the brightness of the backlight.

Image display device, control method for image display device, and recording medium recording control program

A display includes a backlight portion having at least one broad spectrum emitter (such as white) and at least one narrow spectrum emitter (such as red, green, and blue), a liquid crystal panel for displaying an image by spatial light modulation, and control electronics configured to receive input image data and output control signals to both the backlight portion and liquid crystal panel. The control electronics is configured to use color rendering capabilities of the liquid crystal panel under illumination from each of the emitter types individually to calculate a minimum power combination of emission from each emitter type required to display the input image data. The control electronics is further configured to modify the input image data according to the calculated minimum power combination of emitter powers so a resulting display of colors in the image data remains despite changing illumination conditions.
