ADDITIVE FOR IMPROVING OPTICAL PERFORMANCE OF AN ELECTROPHORETIC DISPLAY |
摘要 |
The present invention is directed to an electrophoretic fluid which comprises uncharged or lightly charged neutral buoyancy particles. The resulting fluid can improve not only image stability but also contrast ratio of a display device, without significantly affecting the switching speed. The present invention is also directed to an electrophoretic display comprising display cells filled with the electrophoretic fluid. |
