Abstract
Existing computer monitors do not provide sufficient thermo-mechanical and geometric stability required for hyper-realistic telepresence. This disclosure describes techniques to achieve nearly zero deformation through the thermal cycle of a display by adding reinforcements to the interior of the display backplate. The reinforcements are made of a material such as carbon fiber that has a coefficient of thermal expansion much lower than that of the metal backplate. To reduce stored elastic energy induced by thermal stress, reinforcements are attached to the display backplate at their ends. The reinforcements span areas of symmetric distortion on the display, such that sections of unwanted motion oppose each other. The reinforcements are covered with light reflective material such that they integrate well into the display backlight unit. To avoid dark areas in the display, the surface normal vectors to the exterior of reinforcement elements intersect the front of the display.
