摘要:
An active display can have an increased color gamut and include a group of LED packets that each form a sub-pixel and that together form a pixel for the display. Each LED packet includes at least a red primary color LED, a greed primary color LED, and a blue primary color LED. Each LED can be associated with an intensity value to control the intensity of primary light outputted by the LED. The group of LED packets can output light in a color gamut of a color space for the active display. Each LED packet of the group of LED packets, individually, is configured to output light in the color gamut of a subset of the color space. The active display can display a visual media presentation to an audience. An increased fraction of LEDs from a production batch can be used in the active display.

Disclosed is a method and apparatus for power saving techniques. The method may include identifying at least one portion of the display, associated with an application, that may be adjusted, wherein the at least one portion of the display is less than an entire area of the application. Furthermore, the method may include, determining one or more parameters for the identified at least one portion of the display. Additionally, the method may include adjusting the identified at least one portion of the display based on the one or more parameters.

Implementations of the present disclosure are directed to a method, a system, and an article for deriving images of different colors from an original image in an original color. An example computer-implemented method can include: (a) receiving at a client device a first image comprising a first color; (b) shifting the first color of the first image on the client device to create a derived image comprising a new color not present in the first image; (c) presenting the derived image as an element of a graphical user interface on the client device; and (d) repeating steps (b) and (c) to create and present a plurality of derived images comprising a plurality of new colors.

In some examples, an electronic device includes a display panel comprising a plurality of pixels; and a controller to, for achieving power saving at the electronic device, select a theme from a plurality of themes that specify respective different display characteristics of displayed content, the different display characteristics including different colors, and based on the selected theme, change a display characteristic of the displayed content, the changing of the display characteristic including changing a color displayed by a portion of the plurality of pixels from a first color to a second, different color.
摘要:
A user interface adaptation module identifies a dominant color of a frame of a video and, based on the dominant color, generates colors for components of a user interface in which the video is displayed. The colors of the user interface components are set based upon the generated colors and upon context information such as a playing state of the video. The setting of the component colors in this way allows the user interface to adjust to complement both the played content of the video and the video's context. In one embodiment, the dominant color is identified by partitioning individual pixels of the frame based on their respective colors. In one embodiment, a set of primary color variants is generated based on the dominant color, and different colors are generated for each type of user interface component based on the different primary color variants.

Examples of a light field metrology system for use with a display are disclosed. The light field metrology may capture images of a projected light field, and determine focus depths (or lateral focus positions) for various regions of the light field using the captured images. The determined focus depths (or lateral positions) may then be compared with intended focus depths (or lateral positions), to quantify the imperfections of the display. Based on the measured imperfections, an appropriate error correction may be performed on the light field to correct for the measured imperfections. The display can be an optical display element in a head mounted display, for example, an optical display element capable of generating multiple depth planes or a light field display.
