Patent ID: 8264648

Claim:
An electro-optical module comprising: a chassis with an inner surface and defining an opening into the electro-optical module; an electro-optical panel having a first transparent panel and a second transparent panel, the first and second transparent panels disposed on opposite sides of the electro-optical panel, the electro-optical panel also including a first polarization film and a second polarization film, the first polarization film being disposed on and abutting an outer surface of the first transparent panel, the second polarization film being disposed on and abutting an outer surface of the second transparent panel; and a transparent protector disposed on and abutting the first polarization film of the electro-optical panel, the transparent protector abutting the inner surface of the chassis, the transparent protector extending across the opening of the chassis to be exposed externally via the opening, the transparent protector being disposed between the inner surface of the chassis and the first polarization film; wherein the transparent protector has a stack structure including only a first transparent protection layer and a second transparent protection layer, the first transparent protection layer abutting the first polarization film, the first transparent protective layer formed of an elastic material, the first transparent protection layer being disposed between the second transparent protection layer and the electro-optical panel, the first transparent protection layer being made of an adherent, gel-type material, the second transparent protection layer and the electro-optical panel adhering together via the first transparent protection layer, wherein a thickness of the first transparent protection layer is greater than a thickness of the second transparent protection layer by a ratio of the thickness of the first transparent protection layer to the thickness of the second transparent protection layer of at least 1.3, and wherein a dynamic elasticity value of the second transparent protection layer is at least ten times higher than a dynamic elasticity value of the first transparent protection layer within a frequency range of 1 to 10 Hz.
