Autostereoscopic display screen and autostereoscopic display device using the same

An autostereoscopic display device, comprising:

• an autostereoscopic display screen comprising:
• a light-deflecting component configured to allow a light beam to pass through it, thereby deflecting the light beam to travel towards multiple directions;
• and
• a double-sided lenticular lens disposed at a side of the micro-light-deflecting component, the double-sided lenticular lens comprising:
• a central portion;
• a first cylindrical lens array disposed on the central portion and located between the light-deflecting component and the central portion, wherein the first cylindrical lens array comprises a plurality of first cylindrical lenses, and each of the first cylindrical lenses has a first length in a first direction;
• and
• a second cylindrical lens array disposed on the central portion such that the central portion is located between the first cylindrical lens array and the second cylindrical lens array, the second cylindrical lens array comprising a plurality of second cylindrical lenses and each of the second cylindrical lenses having a second length in the first direction, wherein the first length of the first cylindrical lenses is greater than the second length of the second cylindrical lenses, and wherein the first cylindrical lens array, the central portion, and the second cylindrical lens array are arranged along an axis that is substantially perpendicular to the first axial direction, wherein the light-deflecting component comprises a light entry surface and a plurality of micro prisms, the micro prisms are located between the light entry surface and the double-sided lenticular lens and arranged along a second direction, the first direction is slanted at an angle relative to the second direction, and the angle is in a range from 30 degrees to 60 degrees;
• and the autostereoscopic display device further comprising an image emitter disposed at a side of the autostereoscopic display screen, wherein the light-deflecting component is optically coupled between the image emitter and the double-sided lenticular lens, and the image emitter is configured to emit towards the autostereoscopic display screen an image signal comprising a plurality of images provided in a time sequence.
