A mixture containing a catalyst and a resin is provided where either the catalyst or the resin (or both) are encapsulated. The mixture is applied to a glass component. The mixture may be exposed to ultraviolet light causing the capsules to release the portions contained therein and combine to form an adhesive (this may be done before or after applying the mixture to the glass component). A second glass component is then placed on the adhesive so that the adhesive is interposed between the glass components. Alternatively, the mixture may be exposed to UV light after the second glass component is placed. An exemplary method uses a frame to create a uniform thickness of adhesive. Barrier coats and skirting tape may also be used.
A system and method for controlling subsections of an LED backlight for a liquid crystal display (LCD). Exemplary embodiments analyze the histograms for each subsection of the LCD which corresponds with the subsections of the LED backlight in order to produce a proper luminance for the backlight subsection. The proper luminance may be less than the maximum or typical luminance that is produced by common LED backlights. By reducing the luminance the resulting display can have less power consumption, longer lifetime, and higher contrast ratios. The original subpixel voltages for the LCD are re-scaled based on the proper luminance for the backlight subsection. Virtual backlight data may be created to simulate the luminance at each subpixel and the virtual backlight data may be used to re-scale the original subpixel voltages. The virtual backlight data may be used to blend between adjacent subsections of the LED backlight which may be producing different levels of luminance.

The lights in the assembly may be any one of the following: light emitting diodes (LED), organic light emitting diodes (OLED), field emitting display (FED), light emitting polymer (LEP), and organic electro-luminescence (OEL). Embodiments also allow tiles to be removed from the rear of the display and dissipate heat from the lights to the rear of the backlight assembly.
Embodiments relate generally to various thermal control features for electronic displays. One feature comprises a closed loop isolated gas chamber, where a first chamber is in contact with the display surface and transfers heat between the isolated gas and the display surface. A second chamber is in gaseous communication with the first chamber and is adapted to heat or cool the isolated gas and reintroduce the isolated gas into the first chamber. Another feature uses constricted convection to facilitate the cooling of the backlight assembly for the electronic display. Another feature uses an air curtain to further heat or cool the exterior viewing surface of the display. Another feature uses a linear polarizer with an insulating gap to reduce the solar loading of the display stack and provide insulation from the ambient air temperature. Another feature uses a fluid system to contact fluid coolant with the display surface in order to cool the display. Each of the features may be used alone, or in combination to provide the proper operating temperature for the display depending on its desired operating environment.
