Abstract: A display driver comprises drive circuitry and emission control circuitry. The display driver is configured to drive a display panel. The display panel may be a self-luminous display panel. The emission control circuitry is configured to generate a control signal to control the display panel during a first frame period to successively move a plurality of non-light-emitting areas successively inserted at an end of a display area of the display panel in a predetermined direction, the plurality of non-light-emitting areas having gradually changing widths in the predetermined direction.

Abstract: A display driver comprises gamma processing circuitry, compensation circuitry, and driver circuitry. The gamma processing circuitry is configured to process the image data to generate gamma processed image data. The compensation circuitry is configured to process the gamma-processed image data, based on a ratio of a number of display elements that emit light to a total number of display elements of a display panel, to generate compensated image data. The driver circuitry is configured to drive the display panel based on the compensated image data.

Abstract: A method comprises acquiring measured luminance levels at a measurement point of a display area for a plurality of test images displayed in the display area, and estimating one or more luminance levels at one or more corresponding luminance estimation points of the display area using the measured luminance levels. The method further comprises determining, based on the one or more estimated luminance levels, a correction parameter using the estimated one or more luminance levels.

Abstract: A display driver that drives a display panel comprises storage circuitry, color addition processing circuitry, and drive circuitry. The storage circuitry stores F subpixel data acquired from color coordinate data indicating color coordinates of a displayed color in a predetermined color space displayed on the display panel when an R subpixel, a G subpixel, and a B subpixel in each of a plurality of pixels of the display panel are driven with drive signals corresponding to a minimum grayscale value and an F subpixel in each of the plurality of pixels which displays an additional color other than a primary color R, a primary color G, and a primary color B is driven with a drive signal corresponding to a maximum grayscale value. The color addition processing circuitry generates output FRGB data from input RGB data, in response to the F subpixel data stored in the storage circuitry.

Abstract: A display driver comprises signal supply circuitry and control circuitry. The control circuitry is configured to generate a first luminance value using a DBV. The signal supply circuitry is configured to supply to a display panel at least one signal using the first luminance value. The first luminance value has a one-to-one correlation with the display brightness level. The DBV does not have a one-to-one correlation with the display brightness level.
