A display driver includes first interface circuitry, a graphic memory, image processing circuitry, and drive circuitry. The first interface circuitry is configured to receive an edge illumination command from a controller external to the display driver. The graphic memory is configured to store image data. The image processing circuitry is configured to render an edge-illuminated image by overlaying an edge illumination graphic on a first image corresponding to the image data in response to the edge illumination command. The edge illumination graphic extends along an edge of a display region of a display panel. The drive circuitry is configured to drive the display panel based on the edge-illuminated image.

Aspects of the present invention relate to methods and systems for measuring and managing the brightness of digital content in a field of view of a head-worn computer.

According to an aspect, a display device includes a pixel including a first sub-pixel configured to emit light having a peak in a spectrum of red, a second sub-pixel configured to emit light having a peak in a spectrum of green, and a third sub-pixel configured to emit light having a peak in a spectrum of blue. The first sub-pixel, the second sub-pixel, and the third sub-pixel are inorganic light-emitting diodes. A light emission intensity of the second sub-pixel is increased at a predetermined ratio with respect to a light emission intensity of the first sub-pixel when the first sub-pixel emits light at a light emission intensity within a low-luminance range equal to or lower than a predetermined level of luminance.

A computing device includes an image sensor, an IMU, a display, and a processor coupled to the image sensor, the IMU, and the display. The processor is configured to generate a GUI current screen on the display. The GUI current screen includes a background, and foreground GUI elements overlaying the background. The processor is configured to when the IMU generates motion data indicative of movement, render the background to comprise a video image from the image sensor.

A video input interface receives input video data in a normal state. A control input interface receives character data for On Screen Display (OSD) in a setup state. An encoder encodes the character data and stores encoded compressed data in a memory in the setup state. A decoder receives an instruction signal designating the character data to be displayed, reads and decodes one piece of compressed data corresponding to the instruction signal from the memory, and reproduces the original character data in the normal state. A multiplexer superimposes character data on frame data and outputs the data.

Displays and eyewear devices incorporating displays are disclosed. One display includes a light source, a first display region, and a second display region. The first display region includes a first contiguous array of pixels. The first contiguous array of pixels includes a first group of pixels and a second group of pixels interspersed with the first group of pixels. The first group of pixels is adapted to emit light from the light source in only a first wavelength band and the second group of pixels is adapted to emit light from the light source in only a second wavelength band different from the first wavelength band. The second display region consists essentially of a second contiguous array of pixels. The second contiguous array of pixels is adapted to emit light from the light source in a predetermined wavelength band.

A color calibration module applied to an electronic device is provided. The electronic device includes a screen. The screen includes an edge. The color calibration module includes a base and a body. The base is detachably disposed on the edge. The body includes a first end and a second end. The first end is rotatably connected to the base through a rotating shaft, and the second end includes a color calibration detecting head. An electronic device including the color calibration module is further provided.

A subtractive color change system for displaying a selected color to a viewer and a method of changing color. The system includes a layered assembly having transparent panels of primary and key colors, with a fixed-color background behind the layered assembly. The subtractive color change system may have a control unit to individually control the intensities and values of the primary color panels to render a color and to control the intensities and values of the panels in the layered assembly to reduce differences between the color rendered and the selected color and to display the selected color to a viewer.

A display system comprising a foveal display having a monocular field of view of at least 1 degree is positioned within a scannable field of view of at least 20 degrees, the foveal display positioned for a user. In one embodiment, the foveal display is positioned for the user's fovea.

A display system including a tracking subsystem configured to track one of a pose of a head of a viewer or a pose of an eye of the viewer. The display system further includes an image correction module configured to, for each pixel of at least a subset of pixels of an input image, determine a pixel view angle for the pixel based on the pose of the head or the pose of the eye, determine a corrected pixel value based on an input pixel value of the pixel in the input image and based on the pixel view angle; and provide the corrected pixel value for the pixel in an angle-corrected image corresponding to the input image. The display system further includes a display panel to display the angle-corrected image.
