Transflective LCD technology can be applied to certain selected regular TFT LCD to provide the LCD with a reflective function. 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 lighting conditions including direct sunlight.
How does this technology work?=Transflective LCD modules hold both transmissive and reflective properties, and the method of image display depends upon the conditions of the ambient environment. The display uses a backlight with a transmissive property in dark environments, and uses external light with a reflective property in bright environments. Our improved transflective method allows for better colour performance, which provides excellent colour characteristics similar to the transmissive mode. The net Reflectance rate of our Transflective LCD solution is from 0.9% to 1.3% varied from panels selected. For example, with 1.3% net reflectance rate and under 10,000 ambient sunlight conditions, the brightness gain is around 130 nits added to original backlight brightness.
Handling Cautions=Keep temperature at 0~50XC (32-121XF) and Avoid direct sunlight on the display. Although transflective LCD is mainly used in outdoor environment and can increase the effective lights under sunlight, it is suggested that user should keep the LCD within suggested temperature peramiters for operation and storage.
Arrange proper contrast ratio to ambient light=Contrast ratio is a critical factor that can influence the readability. For example, if you put the LCD in very high ambient light environment; even if the brightness of display is pretty high; the contrast between the ambient light and the display is too low. Therefore, we might not be able to see the clear LCD screen image. In order to be sunlight readable, the contrast ratio to the ambient light need to be in proper range.
Use SAW/ IR touch or Low reflectance rate Glass=If you demand for built-in protection glass, it is needed to use the material whose reflectance rate is less than 1%. It should be careful when using protection glass. Generally, the reflectance rate of protection glass can be as high as 4~6%, but we can provide the reflectance ration glass which is less 0.6%, so that the sunlight readability performance can work very well
