High-definition clear color images without a backlight and color filter
This Reflective STN Color LCD is based on a newly developed electrically controlled birefringence (ECB*) technology that delivers a high-brightness, high- definition display with low power consumption while eliminating the need for a backlight and color filter. It is capable of delivering a true black display more sharply defined than previously possible, and this new color LCD display achieves crisp, clear reproduction of both text and images.
1. A single pixel allows a continuous color display of white, black, blue, green and red:
The unit offers a true black display that makes it possible to deliver crisp and clear presentations of both text and images.
2. Bright background colors:
New phase differential plate, a new liquid crystal material system, as well as reflector with high reflectivity, make it possible to attain bright, vivid background colors.
3. Low power consumption:
Like the standard-type STN LCD unit, the ECB-method STN color LCD unit eliminates the need for a backlight and thus reduces the power consumption level.
* Electrically Controlled Birefringence (ECB) Changing the voltage applied to the liquid crystal layer modifies the tilt of the liquid crystal molecules. The resulting change in birefringence of the liquid crystal layer is detected by the two polarizers. This system is used for color displays.
