A dual‐gap RGBW transflective TFT‐LCD with adjustable color gamut

— An adjustable-color-gamut dual-gap RGBW transflective liquid-crystal display that uses a four-color manufacturing process and a color-processing algorithm to achieve the appropriate color performance in both the transmissive and reflective modes is presented. Based on superior-color-transformation units, the total brightness and color gamut can be modified under different ambience. The highest NTSC color gamut in the reflective mode (reflectance, 4.4%) that has been fabricated successfully for a RGBW 1.5-in. dual-gap panel is 23% with a 7%, 17%, and 40% NTSC color gamut in the transmissive mode by using different algorithms. Compared to a typical RGB panel, it not only provides flexibility for any environment but also satisfies a variety of personal requirements. Based on personal preference, users have more choices to adjust the LCD settings such as color saturation, brightness, etc. The smart RGBW TRLCD will definitely become the developing trend towards sunlight-readable LCDs in the near future.
