DISPLAY WALL COMPRISING MULTIPLE DISPLAYS AND METHOD OF OPERATION THEREOF
The display wall comprises a plurality of display modules, each have a screen held in place with a plurality of pins at the screen's perimeter. A processor adjusts border brightness such that adjacent border areas of adjacent screens match brightness within about 5% of each other.
1 A display wall comprising:
a plurality of display modules, each module having a screen and a light engine capable of projecting an image onto a screen of the module; and
a fixture having ribs and pins; the pins holding the plurality of screens in place via the screens' perimeters.
2 . The display wall of claim 1 , wherein each module further comprises a camera that images a screen of the module and at least a portion of a screen of an adjacent module.
3 . The display wall of claim 2 , wherein each pin includes an identification feature visible to the camera.
4 . The display wall of claim 3 , wherein each module further comprises a processor communicatively coupled to the camera and light engine and is capable of aligning projected images using the identification feature of the pins.
5 . The display wall of claim 1 , wherein the pins are formed and placed outside of the path of the projected images.
6 . The display wall of claim 5 , wherein the pins are conical.
7 . The display wall of claim 1 , wherein each module comprises a mirror coupled to the fixture and wherein the light engine of each module projects an image that reflects off the mirror onto a screen of the module.
8 . A display wall comprising:
a plurality of display modules, each module having a screen and a light engine that projects an image onto the screen;
a camera capable of imaging a screen of a display module and at least a portion of a screen of an adjacent module; and
a processor, communicatively coupled to the camera and at least one light engine, capable of adjusting brightness of the at least one light engine such that a projected image from the at least one engine matches brightness of the at least a portion of a screen of an adjacent module within about 5%.
9 . The display wall of claim 8 , wherein the processor is further capable of adjusting brightness uniformity of the light engine.
10 . The display wall of claim 9 , further comprising a coefficient table and wherein the processor adjusts the brightness uniformity using the coefficient table.
11 . The display wall of claim 8 , wherein each module comprises a processor coupled to the camera and the light engine; wherein the display wall further comprises a video distributor capable of distributing video data of the imaged screens among the processors.
12 . The display wall of claim 8 , wherein the at least a portion of a screen of an adjacent module includes a border area.
13 . A method of adjusting brightness in a display wall, comprising:
displaying images on screens of the display wall;
imaging the screens;
determining brightness of border areas of the screens; and
matching brightness of border areas in a screen to within about 5% of border areas of an adjacent screen.
14 . The method of claim 13 , further comprising adjusting brightness uniformity of each of the images projected onto the screens.
15 . The method of claim 14 , wherein the adjusting the brightness uniformity uses a coefficient table.
16 . The method of claim 13 , wherein the imaging the screens uses a single camera and further comprising splitting video data from the camera to processors corresponding to each screen.
17 . A system for adjusting brightness in a display wall, comprising:
means for displaying images on screens of the display wall;
means for imaging the screens;
means for determining brightness of border areas of the screens; and
means for matching brightness of border areas in a screen to within about 5% of border areas of an adjacent screen.
