  • Patent number: 8879042
    Abstract: An exemplary embodiment relates to a cooling system and a method for cooling an electronic display. A preferred embodiment includes a transparent gas cooling chamber. The transparent gas cooling chamber may have a linear polarizer. The components in the system are preferably housed within the electronic display housing. The cooling chamber defines a gas compartment that is anterior to and coextensive with the electronic display surface. Fans may be used to propel the isolated gas through the cooling chamber. The circulating gas removes heat directly from the electronic display surface by convection. The isolated gas is transparent or at least semi-transparent. The image quality of an exemplary embodiment remains essentially unchanged, even though the gas is flowing through a narrow channel over the visible face of the electronic display surface.

  • Patent number: 8854593
    Abstract: In an active matrix semiconductor display device in which pixel TFTs and driver circuit TFT are formed on the same substrate in an integral manner, the cell gap is controlled by gap retaining members that are disposed between a pixel area and driver circuit areas. This makes it possible to provide a uniform cell thickness profile over the entire semiconductor display device. Further, since conventional grainy spacers are not used, stress is not imposed on the driver circuit TFTs when a TFT substrate and an opposed substrate are bonded together. This prevents the driver circuit TFTs from being damaged.
