- Abstract
We fabricated two types of 6.05-in. active matrix reflective liquid crystal displays (LCD) using a c-axis-aligned crystalline oxide semiconductor (CAAC-OS) for the driver circuit and field-effect transistors in pixels: one is of the high-reflectance type, and the other is of the wide-gamut type. Because of the small off-state current of the CAAC-OS and the improved liquid crystal material, low-frequency driving at 1/60 fps or lower was achieved without memory in a pixel. Consequently, the still image display does not require data writing, except in turning pages; thus, it is flicker-free in still image display. We also examined the page-turning operation for less eye strain. The study shows that a reflective color LCD using a CAAC-OS results in eye-friendly still image display without flicker similar to an electrophoretic display (EPD); however, it is capable of moving image display, color display, and eye-friendly page-turning operation, which are difficult to achieve with an EPD.
