Abstract

A digital photo frame includes a frame, a light gathering lens, a reflector, and a transmissive LCD module. The frame includes a front side, a rear side, and a receiving hole through the front side and rear side. The light gathering lens array is pivotedly mounted on the rear side of the frame, the light gathering lens array being rotatable about two upper pivot pins. The reflector is pivotedly mounted on the rear side of the frame corresponding to the light gathering lens array, the reflector being rotatable about two lower pivot pins parallel to the upper pivot pins. The transmissive LCD module is received in the receiving hole adjacent to the front side.

Claims

1. A digital photo frame comprising:

a frame comprising a front side, a rear side, and a receiving hole through the front side and rear side;

a light gathering lens array pivotally mounted on the rear side of the frame, the light gathering lens array being rotatable about two upper pivot pins;

the light gathering lens array comprising a light emitting surface, the light gathering lens defining a locating groove in the light emitting surface;

a reflector pivotally mounted on the rear side of the frame corresponding to the light gathering lens array, the reflector being rotatable about two lower pivot pins parallel to the upper pivot pins;

the reflector comprising a flange for engagement in the locating groove; and

a transmissive LCD module received in the receiving hole adjacent to the front side;

wherein the reflector forms 45 degrees with the light gathering lens array and the transmissive LCD module respectively when the flange engages in the locating groove.

2. The digital photo frame in claim 1, further comprising an optical film layer array, the optical film layer array is received in the receiving hole adjacent to the rear side.

3. The digital photo frame in claim 2, further comprising a diffuser, the diffuser is received in the receiving hole, and is lay between the transmissive LCD module and the optical film layer array.

4. The digital photo frame in claim 1, further comprising a support member, the support member pivotally coupled to the reflector and configured for supporting the reflector.

5. The digital photo frame in claim 1, wherein the light gathering lens array is configured for condensing and directing light rays to the reflector.

6. The digital photo frame in claim 5, wherein the reflector is configured for reflecting the light rays from the light gathering lens array to the transmissive LCD module.
