1.3 Optimized Use of the Sunlight-Readable Touchscreen.
With the imposed reflective function, the modified LCD can reflect the ambient light
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 most lighting conditions. The optimized angle of view is
fourty-five degree. And the optimized distance of view is 30cm.
**Caution
Although the transflective LCD is made for outdoor environments, it is
suggested that you keep the LCD in appropriate temperature for operation and
storage, and avoid direct sunlight if possible. To ensure stable operations of the
transflective LCD, 0~50°C (32-121°F) operation and storage temperature is
suitable.
