L-6: Late-News Paper: Development of the Novel Transflective LCD Module Using Super-Fine-TFT Technology

Adopting the new structure of planarization layer on the rough reflector and designing the new optical compensation with large cell gap margin, we developed the wide viewing angle transflective LCD module with our proprietary IPS technology (Super-Fine-TFT technology). After measuring the viewing-angle characteristics, the developed transflective IPS-LCD is shown to surpass the VA mode in the transmissive performance.

Transflective IPS‐LCD with improved reflective contrast ratio

— In order to improve the reflective contrast ratio of transflective IPS-LCDs, a novel pixel design for a normally white reflective IPS has been proposed. In this design, the large-inter-electrode-spacing layout using a novel driving method and a double-layered electrode have effectively reduced the light leakage. By applying these two technologies, a transflective IPS-LCD has been successfully demonstrated with a high contrast ratio (15:1) in the reflective mode and a wide-viewing-angle characteristic in the transmissive mode.

69.3: Transflective IPS‐LCD with Improved Reflective Contrast Ratio

We devised the novel driving method for large inter-electrode spaces and the double layer electrode of the transflective IPS-LCD. Applying these two technologies, we developed the transflective IPS-LCD which had a high contrast ratio (15:1) in the reflective mode and wide viewing-angle characteristics in the transmissive mode. This reflective contrast ratio is well-improved in transfective IPS-LCDs.
