Enhanced View TFT Technology
Consistent high luminance and high reflectivity (R-EVT)
Transflective LCDs are comprised of a backlit transmissive field and a reflective field that utilizes ambient light. The distribution of pixels in the two zones largely determines the basic performance in the transmissive mode and the reflective mode. A larger transmissive field, for example, boosts brightness but reduces the reflection ratio due to a smaller reflective field. A larger reflective field, on the other hand, enhances visibility in bright environments while lowering the transmissive ratio due to a smaller transmissive field.
The R-EVT solves this dilemma through a proprietary optical design that boosts the transmissive ratio of the transmissive field and the efficiency of the backlight. An exclusive reflective plate also enables far more efficient use of ambient light. Thus, brightness in the transmissive mode and the reflection ratio in the reflective mode are significantly increased without affecting backlight power usage. The balance between brightness and reflection ratio can also be optimized to suit different purposes and environments.
EVT is an abbreviation for Enhanced View TFT.
