TrioLCD™: Sunlight Readable LCD Display with Transflective Appearance
A regular transmissive LCD has poor readability in outdoor environments. The common approach solving this problem has been active enhancement. There are some drawbacks associated with this approach, such as extra power consumption, excessive heat generation, and bulky housing. ALP developed a convenient, affordable, and efficient solution for outdoor LCD applications - the TrioLCD. TrioLCD technology is a patented LCD passive enhancement technology, which equips a LCD with ample reflectivity without compromising its original transmissive functions. With the imposed reflective function, the modified LCD can reflect the ambient light passing the LCD cell and use the reflected light beams as its source of illumination. Hence the stronger the ambient light, the greater the reflective luminance of the LCD and the brighter the LCD would appear (Fig. 1). In fact, a TrioLCD is visible under strong ambient light even without its backlight on, as shown in Fig. 2. Please contact us for further information.
