Abstrakt: Compared with cholesteric display technology, which is mainly a passive driver under 5inch, this paper report one 7.5inch actively driven bistable display device. We use cyan cholesteric liquid crystal reflecting 528nm light and red ink to achieve red & white dual color display. In order to enrich the display information, one red (660nm) cell and one cyan (528nm) cell are fitted with pixel precision, and black ink is printed on the bottom, control the status of the two cells respectively, so as to achieve red, cyan, black, and white four color display. In addition, we optimized drive mode, and update traditional two‐stage drive to three‐stage drive, which improved the stability of the LCD FC state and the image quality of the display device, especially at high and low temperatures. In this paper, red&white dual color and four color display technologies are the first in the LCD industry. [ABSTRACT FROM AUTHOR]
