Transflective LCD (TRLCD) panel enhancement. (Sunlight viewable LCD's)

It is obvious that the market demand for outdoor LCD applications are expanding, such as mobile navigator/video systems, Tablet PC, Kiosk displays, ATM and PDA, etc. However, a regular transmissive LCD has poor readability in outdoor environments. To provide a suitable solution, Advanced Photonics devoted years of R&D efforts in developing convenient, affordable, and efficient solutions for outdoor LCD applications. TRLCD® technology is a patented LCD enhancement technology, which is developed based on our knowledge in optics in addition to the learning and understanding of the optical properties of a transmissive LCD. The overall optical performances of a TRLCD® are properly summarized in its name - Transmissive and Reflective optimized LCD, which implies that we put our effort to optimize the LCD passively.

The enhancement is designed to equip a LCD with sufficient reflective function without compromising its original transmissive functions and features. 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, Figs. 1 and 2. A TRLCD® also comes with improved optical characteristics, such as brightness, contrast ratio, viewing angle and color saturation for both indoor and outdoor viewing, Figs 3 and 4. The superb optical quality of a TRLCD® in an outdoor environment is achieved without extra power consumption and excessive heat generation with no mechanical alteration necessary, Fig. 5. Its unique transflectivity under direct
sunlight has won over many customers who are power and heat conscious. TRLCD® offers a truly convenient and affordable solution for your various outdoor LCD applications.
