Abstract

A novel transflective LCD with micro-tube array structure is demonstrated to make most backlight be utilized effectively. By redistributing the area ratio of transmissive and reflective regions, high light efficiency in both transmissive and reflective sub-pixels can be yielded. Based on the principle of light collecting, a simulation model was established to characterize the features and optimize micro-tube array structure. Furthermore, a typical TFT-LCD process was utilized to fabricate the optimized structure. A prototype of micro-tube array was fabricated, and the measured enhancement of backlight utilization efficiency can be a factor of 1.81.
