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.

Abstract: A display driver for driving a display panel includes a voltage data generator circuit calculating a voltage data value from an input grayscale value and a driver circuitry driving the display panel in response to the voltage data value. The voltage data generator circuit includes a basic control point data storage circuit storing therein basic control point data specifying a basic correspondence relationship between the input grayscale value and the voltage data value, a correction data memory storing correction data for each of the pixel circuits, a control point calculation circuit and a data correction circuit. When the voltage data value is calculated for a specific pixel circuit, the control point calculation circuit generates control point data associated with the specific pixel circuit by correcting the basic control point data on the basis of the correction data associated with the specific pixel circuit, and The data correction circuit calculates the voltage data value from the input grayscale value on the basis of the correspondence relationship specified by the control point data associated with the control point data.

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 system and method for encoding, transmitting and updating a display based on demura calibration information for a display device comprises generating demura correction coefficients based on display color information, separating coherent components from the demura correction coefficients to generate residual information, and encode the residual information using a first encoding technique. Further, the image data may be divided into data streams, compressed and transmitted to from a host device to a display driver of a display device. The display driver decompresses and drives subpixels of the pixels in based on the decompressed data. The display driver updates the subpixels of a display using corrected greyscale values for each subpixel are determined from the decompressed data.

Abstract: An example method of illuminating an optical fingerprint sensor integrated with a display, where the display includes a fingerprint (FP) pixel region and an outer pixel region exclusive of the FP pixel region, is described. The method includes: processing image data in display driver circuitry configured to drive the display to present an image; adjusting a first brightness setting, during the processing of the image data, corresponding to both the FP pixel region and the outer pixel region to provide illumination for the optical fingerprint sensor; and adjusting a second brightness setting, during the processing of the image data, corresponding to only the outer pixel region.

Abstract: A display driver comprises: subpixel rendering (SPR) circuitry configured to use, in SPR, predetermined regions which fall within two lines of input subpixels of an input image; buffer memory circuitry configured to store first subpixel data for a plurality of first subpixels of the input subpixels, wherein the plurality of the first subpixels each are encompassed in the predetermined regions; and a register configured to store coefficients, wherein the coefficients respectively correspond to shapes of the portions of the first subpixels encompassed in the predetermined regions. The SPR circuitry is configured to calculate second subpixel data for second subpixels of an output image, based on the first subpixel data stored in the buffer memory circuitry and the coefficients stored in the register.
