Systems, methods, and computer readable media to improve the operation of a computer's display system are described. In general, techniques are disclosed for retaining glyph-mask information for text associated with a region that may be arbitrarily moved across a screen. More particularly, techniques disclosed herein utilize an additional off-screen buffer referred to as the glyph-mask buffer. The glyph-mask buffer coincides with an existing side buffer in extent, but is used only to retain anti-aliased glyph information (i.e., glyph-masks). When the side buffer's content is updated, the effect of that update on the region's text may be reflected in an update to the glyph-mask buffer. At display time, the region corresponding to the side buffer, and the text therein, may be properly rendered at any screen location by combining the screen's target display area (background), the side buffer and the glyph-mask buffer.

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.

An initial current ratio calculation unit obtains an initial current ratio for each pixel based on a current measurement result by a data line drive/current measurement circuit. A light emission current efficiency calculation unit obtains a light emission current efficiency for each pixel referring to an LUT, based on a measured operating temperature and the initial current ratio. A first correction unit corrects a video signal for each pixel in view of characteristics of each pixel, based on the current measurement result and the light emission current efficiency. A second correction unit obtains a correction term for each pixel in view of a difference in the light emission current efficiency compared to neighboring pixels, based on a two-dimensional distribution of the light emission current efficiency. The correction term obtained by the second correction unit is added to the video signal corrected to obtain a corrected video signal.

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.

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 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.

Disclosed are a page display method and apparatus, which relate to the display field. The method includes: rendering a current page to be displayed to obtain a page image; acquiring gray values of pixels in the page image; determining a display mode according to the acquired gray values, the display mode including a white mode and a black mode; judging whether the display mode matches a screen light-emitting type, the screen light-emitting type including backlight light-emitting and self light-emitting; and performing color inversion processing on the page image and displaying the processed page image when the display mode does not match the screen light-emitting type.

A graphics system interleaves a combination of graphics renderer operations and compute shader operations. A set of API calls is analyzed to determine dependencies and identify candidates for interleaving. A compute shader is adapted to have a tiled access pattern. The interleaving is scheduled to reduce a requirement to access an external memory to perform reads and writes of intermediate data.
