Viewing angle switching module and display device |
| abstract |
A viewing angle switching module includes a viewing angle limiter, a first electrically controlled viewing angle switch, a second electrically controlled viewing angle switch, a first polarizer and a second polarizer. The viewing angle limiter has an absorption axis, and the axial direction of the absorption axis is parallel to the thickness direction of the viewing angle limiter. The viewing angle limiter, the first electrically controlled viewing angle switch, the first polarizer, the second electrically controlled viewing angle switch and the second polarizer are arranged overlappingly. The axial direction of the first absorption axis of the first polarizer is parallel to the axial direction of the second absorption axis of the second polarizer. A display device using a viewing angle switching module is also proposed. The viewing angle switching module and the display device proposed by the utility model have better utilization rate of light energy. |
