Exemplary embodiments disclosed herein provide a LCD assembly including an LED backlight, a liquid crystal display (LCD) placed in front of the LED backlight, a glass plate positioned between LED backlight and the LCD; and an optical film positioned between the glass plate and the LCD. In some embodiments, the glass plate is bonded to the rear side of the LCD, generally around the perimeter of the LCD. Preferred embodiments place a diffusing film within a cavity that is defined between the glass plate and the LCD. Some embodiments also bond the backlight cavity walls to the glass plate, on a side opposing the LCD.

The LCD assembly of claim 6 further comprising: a rear thermal plate positioned opposite to the front thermal plate where the space between the front and rear thermal plates defines a gap; anda fan positioned to force external air through said gap. 10. The LCD assembly of claim 9 further comprising: a corrugated layer placed within the gap. 11. The LCD assembly of claim 10 wherein: the corrugated layer contacts the front thermal plate and rear thermal plate in an alternating fashion throughout the gap. 12. A LCD assembly comprising: a liquid crystal display (LCD);a glass plate positioned behind the LCD such that a perimeter of the glass plate is secured to the LCD;backlight cavity walls attached to the glass plate by a layer of adhesive which traverses the majority of the perimeter of the glass plate; anda backlight placed within the backlight cavity walls. 13. The LCD assembly of claim 12 wherein: the backlight cavity walls have a U-shaped cross section. 14. The LCD assembly of claim 12 wherein: the backlight cavity walls comprise a top ledge which attaches to the plate with the layer of adhesive,a bottom ledge substantially parallel to the top ledge, anda sidewall which connects the top ledge with the bottom ledge. 15. The LCD assembly of claim 12 further comprising: a cavity defined between the LCD and glass plate; andan optical film placed within the cavity. 16. The LCD assembly of claim 15 wherein: the optical film comprises a diffusing film. 17. The LCD assembly of claim 15 wherein: the optical film is permitted to move within the cavity, in directions parallel to the film. 18. A LCD assembly comprising: a liquid crystal display (LCD) having a backside;a glass plate bonded to the backside of the LCD, defining a cavity in between the LCD and the glass plate;a diffusing film placed within the cavity; anda backlight positioned behind the glass plate. 19. The LCD assembly of claim 18 wherein: the diffusing film is permitted to move within the cavity. 20. The LCD assembly of claim 18 further comprising: backlight cavity walls which are bonded to the glass plate on a side which opposes the LCD.
