LIQUID CRYSTAL DISPLAY WITH SWITCHABLE VIEWING ANGLE AND METHOD OF VIEWING ANGLE CONTROL |
摘要 |
An LCD with switchable viewing angle includes a first substrate, second substrate, and a liquid crystal layer. The first substrate is provided with a first electrode and a first alignment film. The second substrate is provided with a second electrode, a third electrode and a second alignment film. The liquid crystal molecules adjacent to the first alignment film are tilted at a first pretilt angle. The liquid crystal molecules adjacent to the second alignment film are tilted at a second pretilt angle. The second pretilt angle is in the range of 30° to 50°, and the first pretilt angle is in the range of 0° to 5°. When no bias voltage is applied to the first electrode, the LCD is displayed with a narrow viewing angle; and when a bias voltage is applied to the first electrode, the LCD is displayed with a wide viewing angle. |

1. An LCD (liquid crystal display) with switchable viewing angle, comprising:
a first substrate being provided with a first electrode and a first alignment film thereon; a second substrate being provided with a second electrode, a third electrode and a second alignment film thereon, wherein one of the second electrode and the third electrode is a common electrode, and the other one of the second electrode and the third electrode is a pixel electrode; a liquid crystal layer being disposed between the first alignment film and the second alignment film, the liquid crystal layer comprising a plurality of liquid crystal molecules, wherein the liquid crystal molecules are negative liquid crystal molecules, the liquid crystal molecules adjacent to the first alignment film are tilted at a first pretilt angle, the liquid crystal molecules adjacent to the second alignment film are tilted at a second pretilt angle, the second pretilt angle is in the range of 30° to 50°, and the first pretilt angle is in the range of 0° to 5°; wherein when no bias voltage is applied to the first electrode, the LCD is displayed with a narrow viewing angle; and when a bias voltage is applied to the first electrode to generate a vertical electric field between the first substrate and the second substrate, the LCD is displayed with a wide viewing angle. |
