  • Patent number: 11930682
    Abstract: The present disclosure provides a display panel comprising multiple first, second and third sub-pixels having first, second and third effective light-emitting regions respectively. In a row direction, the first effective light-emitting regions form first rows of effective light-emitting regions, and the second and third effective light-emitting regions are alternately arranged to form second rows of effective light-emitting region. The first and second rows are alternately arranged in a column direction perpendicular to the row direction. A virtual quadrilateral is formed by lines connecting geometric centers of gravity of four first effective light-emitting regions in two adjacent rows and two adjacent columns. Geometric centers of gravity of the second and third effective light-emitting region are located in corresponding virtual quadrilaterals respectively.

  • Patent number: 11804187
    Abstract: An electronic device may include a display having an array of pixels and a backlight that provides backlight illumination for the array of pixels. The backlight may be a direct-lit backlight with a two-dimensional array of light-emitting diodes operable in a local dimming scheme. The electronic device may include control circuitry that provides pixel signals to the array of pixels and backlight signals to the backlight. The control circuitry may adjust the pixel signals and the backlight signals to compensate for brightness and color non-uniformity in the backlight. To compensate for image-dependent backlight non-uniformity, the control circuitry may simulate artificial backlight data based on the target image to be displayed and stored point spread information. To compensate for white-point-dependent backlight non-uniformity, the control circuitry may use measured actual backlight data that describes color variations across the backlight for a given target white point.

  • Publication number: 20220177713
    Abstract: Disclosed are an intumescent fire-retardant coating with ultra-high corrosion resistance and a preparation method thereof. The fire-retardant coating is composed by water, wetting and dispersing agent, defoaming agent, composite carbon-forming catalyst, composite blowing agent, pentaerythritol, titanium dioxide, Mg(OH)2, mica powder, kaolin, anti-rust pigment, aluminum tripolyphosphate, VAE emulsion, freeze-thaw agent, film-forming aid, and thickener. On the basis of the existing fire-retardant coatings, the present disclosure adds a series of anti-corrosion, heat insulation fillers and salt spray resistance additives to achieve a certain salt spray resistance effect. The fire-retardant coating of the present disclosure has both fire-retardant and anticorrosive functions, does not contain organic solvents, is low in price, has high construction tolerance, and has broad application prospects in the field of intumescent fire-retardant coatings.
