Abstract

An autostereoscopic display includes a display panel, a lenticular lens assembly, a driver, a number of camera modules, and a controller. The lenticular lens assembly includes an array of cylindrical lenses and is rotatably hung above the display panel. The driver is configured for driving the lenticular lens assembly to rotate about an axis that is substantially parallel to the lengthwise direction of the cylindrical lenses. The camera modules are arranged beside the display panel and oriented at different angles. The controller is configured for controlling the camera modules to take images in sequence and controlling the driver to rotate the lenticular lens assembly to an orientation at the same angle as a corresponding camera module when the display panel plays an image taken by the camera module.

Claims

1. An autostereoscopic display, comprising:

a display panel;

a lenticular lens assembly comprising a lenticular lens composed of an array of cylindrical lenses and rotatably hung above the display panel;

a driver configured for driving the lenticular lens assembly to rotate about an axis that is substantially parallel to the lengthwise direction of the cylindrical lenses;

a plurality of camera modules arranged beside the display panel and oriented at different angles; and

a controller configured for controlling the camera modules to take images in sequence and controlling the driver to rotate the lenticular lens assembly to be oriented at the same angle as a corresponding camera module when the display panel plays an image taken by the corresponding camera module.

2. The autostereoscopic display of claim 1, further comprising a frame, the frame comprising a rectangular carrying plate, a pair of parallel first side plate and second side plates, and a pair of cantilever plates, the first plates and the second plates extending upward from four edges of the carrying plate, each cantilever plate extending from an edge of a corresponding second plate distant from the carrying plate and toward the other second side plate;

the display panel being positioned on the carrying plate and exposed by an opening defined between the cantilever plates;

the lenticular lens assembly being rotatably connected to the first side plates.

3. The autostereoscopic display of claim 2, wherein each first side plate defines a shaft hole, the two shaft holes are substantially aligned with each other, one of the shaft holes is slightly closer to the carrying plate than the other;

the lenticular lens array extends two shafts from two respective edges of the lenticulalr lens perpendicular to the lengthwise direction of the cylindrical lenses, the shafts are rotatably received in the respective shaft holes.

4. The autostereoscopic display of claim 2, wherein the lenticular lens assembly comprises two connecting plates, the connecting plates extend outward from two respective edges of the lenticular lens and are positioned parallel to the lengthwise direction of the cylindrical lenses;

the driver includes two electromagnetic actuators, each of which is configured for driving a corresponding connecting plate to move towards or away from the carrying plate, each actuator comprises a first magnet, a second magnet, an elastic member, and a winding, the first magnets are positioned on the carrying plate, beneath the respective connecting plates;

the second magnets are secured to the respective connecting plates, the elastic members connect the respective connecting plates to the carrying plate and are configured for balancing magnetic forces generated between the first magnets and the second magnets, the windings are secured to the respective cantilever plates and connect to an adjustable power source.
