2006, Japan – TMD ( Toshiba Matsushita Display Technology, http://www.tmdisplay.com ) announced the development of a new TFT-LCD which realizes high transmittance, wide viewing angle and high speed response by combining two technologies, Optically Compensated Bend (OCB) and Field Sequential.
As Field Sequential technology does not require color filters differing from general color LCDs, this method can realize high transmittance without any absorption loss. In Color filter method, more than 70% of back light brightness is absorbed by color filters. It also maximums 3 times higher resolution without dividing 1 pixel when Color filter method use 3 sub-pixels which shows each RGB to make 1 pixel.
This technology has these great advantages but on the other hand, minimum 3 times higher speed driving to show RGBs is necessary, so high speed response LCD is indispensable to give its full performance.
