Described herein are systems and methods that reduce power consumption for an electronics device including a display. The systems and methods alter video information in a display area and reduce power for a display device when a graphics item is enlarged and the enlargement threatens to increase perceived luminance for the graphics item or increase aggregate luminance for the display area. Altering the video information reduces the luminance of video information in at least the graphics item when enlarged. This may offset perceived luminance gained by human visual processing when an item increases in size. If the graphics item is smaller than the display area after enlargement, then other video information in the display area may also be altered to conserve power.

Aspects of the present disclosure relate to display region filtering. A pixel priority value for each of a plurality of pixels on a display region are assigned in response to identifying portions of the display region for prioritization, wherein the pixel priority values indicate a relative importance of each of the pixels, respectively, for viewing based on a magnitude of the pixel priority values. The pixel priority value of each pixel is compared to a first pixel priority threshold to identify pixels of the plurality of pixels having pixel priority values which do not satisfy the first pixel priority threshold. The pixels of the plurality of pixels having pixel priority values which do not satisfy the first pixel priority threshold are deactivated, wherein a subset of pixels satisfies the first pixel priority threshold and remain active.

The disclosure relates to a method, an apparatus, a device for adjusting screen color, and a storage medium. The method includes obtaining target optical parameters for representing a color space of a screen; calculating a target set of R, G, B components of a target white point based on the target optical parameters; comparing the target set of R, G, B components with a current set of R, G, B components of a current white point of the screen; obtaining adjustment data for the current set of R, G, B components, respectively, based on the comparison; and when the screen is displaying, adjusting the current set of R, G, B components of the screen based on the adjustment data for the current set of R, G, B components.

A display method and a terminal device are provided, so as to resolve a prior-art problem that CPU power consumption of the terminal device is relatively high because a display system of the terminal device processes three procedures in parallel in a Vsync period. The method is: determining, by the display system of the terminal device, a start moment of a first procedure in an (M+1).sup.th Vsync period according to first processing duration of the first procedure in an M.sup.th Vsync period, so that the display system starts to execute a device display procedure before starting to execute the first procedure, the display system delays executing the first procedure in the (M+1).sup.th Vsync period, so that a time required for processing three procedures in parallel in the (M+1).sup.th Vsync period by the display system is reduced, and CPU power consumption of the terminal device is reduced.

A digital painting device and method. The digital painting device includes a generator to generate a color generation signal corresponding to color data in an electronic palette selected by an electronic brush, and a displayer to transmit the color generation signal to a light-emitting module that touches the electronic brush in a time period in which the color generation signal is maintained such that the color data is displayed on the light-emitting module.

A vehicle information display control device includes: an automatic driving information obtaining unit that obtains automatic driving information including information indicating whether each of actuators of a vehicle is in a manual control mode or an automatic control mode; and a display controller that causes a display to display an image based on the automatic driving information. The display controller simultaneously displays a first image and a second image representing the manual control mode and the automatic control mode, respectively, of each of the actuators, and displays (i) the first image of an actuator in the manual control mode closer than the second image of the actuator in the manual control mode and (ii) the second image of an actuator in the automatic control mode closer than the first image of the actuator in the automatic control mode.

A computer-implemented method is provided. The method includes obtaining a first value of a first color setting of an operating system; obtaining a second value of a second color setting of an application on the operating system; and resetting the second color setting of the application to a third color setting based on a combination of the first value and the second value. The third color setting is different from the first color setting, and the third color setting is different from the second color setting.

The present disclosure provides a color correction method, including: in response to original color data of a pixel, converting the original color data into original color coordinates in an original color space; mapping the original color coordinates to a sampling point space to obtain a mapped point corresponding to the original color coordinates in the sampling point space, and determining, according to mapped coordinates of the mapped point, a plurality of reference point coordinates corresponding to the mapped coordinates; obtaining reference point addresses of the reference point coordinates, and simultaneously reading color data of the reference point coordinates according to the reference point addresses; and obtaining corrected color data of the pixel through an interpolation algorithm according to the color data of the reference point coordinates. The present disclosure further provides a Field Programmable Gate Array, a chip and a display device.

A passively and nonintrusively monitoring liquid crystal display (LCD) system includes a graphics controller configured to generate alternating sets of drive instructions and forward the drive instructions for execution by drive electronics to activate display elements of a display surface. An initial set of drive instructions corresponding to a first frame causes the drive electronics to draw an initial pattern such as a solid red fill to selected regions of the display surface. An alternating set of drive instructions causes the drive electronics to draw a contrasting pattern such as a solid cyan fill to the selected regions. Given a sufficiently high refresh rate between the initial and alternating sets, a human operator perceives only the integration of the two patterns unless the display system is in a stuck or frozen state, when the frozen initial and contrasting patterns clearly and quickly indicate the stuck/frozen failure condition.

A method for improving image quality is provided. The method includes: receiving an image data and sensing information; dividing the image data into areas corresponding to different resolutions according to first parameter information, wherein the different resolutions correspond to different frequencies; rendering the areas in a single pass according to the sensing information and the different frequencies and outputting a rendered image data; and resolving the rendered image data into a final output image data with a first resolution according to second parameter information.
