Patent ID: 7837376

Claim:
An image display apparatus, comprising: a light guide plate having a first light emitting surface, a second light emitting surface opposite to the first light emitting surface, and an edge; a light-emitting diode (LED) disposed adjacent to the edge of the light guide plate for projecting light towards the light guide plate; a first transparent substrate disposed adjacent to the first light emitting surface of the light guide plate; a second transparent substrate disposed adjacent to the second light emitting surface of the light guide plate; a transparent film, disposed outside the first transparent substrate or the second transparent substrate, wherein a pattern is formed on the transparent film; and a frame, defining a receiving space where the light guide plate, the LED, the first transparent substrate and the second transparent substrate are disposed therein, the frame comprising a replacement structure, in which the transparent film is adapted to be disposed on or removed from the image display apparatus through the replacement structure; wherein the light is adapted to be guided into the light guide plate from the edge thereof, and outwardly projected through the first light emitting surface and the second light emitting surface; thereby the pattern presented in front of one of the first transparent substrate and the second transparent substrate is capable of being lighted up.
