A technique for masking a non-functioning pixel in a display screen includes receiving pixel values for driving pixels on the display screen with an image, identifying a sub-set of the pixel values associated with surrounding pixels that are adjacent to the non-functioning pixel in the display screen, and adjusting the pixel values of the sub-set to increase brightness of the surrounding pixels to compensate for lost brightness due to the non-functioning pixel to thereby mask visual perception of the non-functioning pixel.

Masking non-functioning pixels in a display

A display panel includes an array of display pixels to output an image. The array of display pixels includes a central pixel region and a perimeter pixel region. The central pixel region includes central pixel units each having three different colored sub-pixels. The different colored sub-pixels of the central pixel units are organized according to a central layout pattern that repeats across the central pixel region. The perimeter pixel region is disposed along a perimeter of the central pixel region and includes perimeter pixel units that increase a brightness of the image along edges of the central pixel region to mask gaps around the array of display pixels when tiling the array of display pixels with other arrays of display pixels.

Bright edge display for seamless tileable display panels

Techniques and mechanisms for displaying an image with structures of a pixel array. In an embodiment, pixels of the pixel array each include three chrominance elements and a fourth luminance element. Of the four elements of a given pixel, a first subset of the elements are aligned along a first line, a second subset of the elements are aligned along a second line offset from the first line, and a third subset of the elements are aligned along a third line extending athwart the first line and the second line, wherein two of the elements are located on opposite sides of the third subset. In another embodiment, image data processing, for displaying an image with the pixel array, includes updating luminance parameters of a plurality of pixel data sets independent of any evaluation to update one or more types of chrominance parameters of the plurality of pixel data sets.

Display pixel structures and method of operating same

Embodiments of a process including determining a position of an observer relative to a pixel array positioned on a diffuse surface, the pixel array comprising a plurality of individual display pixels, determining the observer's viewing angle relative to the pixel array based on the position of the observer relative to the pixel array, and adjusting the brightness of the pixel array so that the brightness of the pixel array when viewed at the observer's viewing angle substantially matches the brightness of the diffuse surface when viewed at the observer's viewing angle. Other embodiments are disclosed and claimed.

Simulation of diffusive surfaces using directionally-biased displays

A display tile for arranging with other display tiles to form a multi-tile display includes display pixels in an active display area, pixel tape sections, and a transparent layer. The pixel tape sections surround the display pixels. Each pixel tape section overlaps an adjacent pixel tape section and is overlapped by another adjacent pixel tape section disposed opposite the adjacent pixel tape section. Each pixel tape section includes a pixel array. The transparent layer is disposed over the display pixels and the pixel arrays of the pixel tape sections. The display pixels and the pixel arrays are arranged to display an overall image of the display tile.

Tileable display with pixel-tape

A display panel includes a carrier substrate, a system interconnect, and a plurality of display modules disposed across the carrier substrate. The display modules are each communicatively coupled to the system interconnect to each output a different portion of an overall image communicated via the system interconnect. Each of the display modules includes an array of direct emission display pixels and a module interconnect to couple the array of direct emission display pixels to the system interconnect. The array of direct emission display pixels of a given display module of the plurality of display modules is distinct and separate from the array of direct emission display pixels of other display modules of the plurality of display modules.

Display panel using direct emission pixel arrays

A tileable display panel includes an array of display pixels including central display pixels near a center of the array having a center pixel pitch and perimeter display pixels along a perimeter of the array. A perimeter region surrounds the array. The perimeter region includes a first side that is joinable to a second side of another instance of the tileable display panel to form a multi-panel display. The perimeter region has a width that is greater than at least half the center pixel pitch such that a gap between adjacent perimeter display pixels of the tileable display panel and the other instance of the tileable display panel when forming the multi-panel display is greater than the center pixel pitch. The gap is visually masked by increasing a characteristic of the perimeter display pixels adjacent to the gap relative to the same characteristic of the central display pixels.

Masking mechanical separations between tiled display panels

A rear projection screen includes an array of pin-hole apertures to pass display light incident from a first side of the rear projection screen through to a viewing side of the rear projection screen opposite the first side. An array of concentrator structures surrounds the pin-hole apertures and defines concentrating optical pathways. The concentrating optical pathways each have an input aperture for collecting the display light and an output defined by a corresponding one of the pin-hole apertures to emit the display light. The input apertures are larger than the pin-hole apertures.
