passing the LCD cell and utilize the reflected light beams as its illumination. The
stronger the ambient light is, the brighter the LCD will appear. As a result, the modified
LCD is viewable under lighting conditions. The optimized angle of view is fourty-five
degree. And the optimized distance of view is 30cm.

increase the reflective lights under sunlight, it is suggested that you should keep
the LCD in appropriate temperature for operation and storage, and avoid direct
sunlight if possible. To ensure the transflective LCD work stably, 0~50°C
