11508322 · 2022-11-22 · ·

A system, method, and computer-readable medium are disclosed for reducing halo artifacts of static images on a computer display. A multimedia stream is received that includes graphical images which are moving and static images as displayed on the computer display. A determination is performed if a graphical image in the multimedia stream is a static image. Additional LED zones of LEDs are turned on to provide backlighting to a computer display panel. A diming algorithm is enabled to adjust LEDs to reduce halo artifacts in the static image. Luminance correction is performed at the pixel level for the static image.

SYSTEM AND METHOD FOR A MULTI-PRIMARY WIDE GAMUT COLOR SYSTEM

Systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

BRIGHTNESS CONTROLS FOR DUAL-SIDED DISPLAYS

In example implementations, a display is provided. The display includes a backlight unit (BLU), a first display panel, a second display panel, and a controller. The BLU includes a first side and a second side. The first display panel includes a first layer of liquid crystals and is coupled to the first side of the BLU. The second display panel includes a second layer of liquid crystals and is coupled to the second side of the BLU. The controller is to set the BLU to a brightness level associated with a first brightness setting of the first display panel and to control the second layer of liquid crystals to set a second brightness setting of the second display panel.

20230055746 · 2023-02-23 ·

A dual-pixel-driver display includes pixels distributed in an array of rows and columns defining a display area and a dual-pixel driver disposed within the display area. Ones of the pixels are grouped in mutually exclusive first and second pixel clusters. The dual-pixel driver comprises a driver input, a first driver output, and a second driver output. The first driver output and the second driver output are both commonly responsive to the driver input. The first driver output drives the pixels in the first pixel cluster and the second driver output drives the pixels in the second pixel cluster.
