Chunghwa Picture Tubes LTD. has successfully developed the 4 inches TN‐type Color‐Sequential TFT‐LCD module with LPAD (Low Power Array Design) structure and novel driving method named Black Data Rehashed Driving (BRD) schema. LPAD structure is designed specially for Color‐Sequential TFT‐LCD, where a pixel consists of only one dot and each pixel are rearranged according to the output polarity of source drivers to obey the dot inversion policy. Hence, the power consumption is reduced directly. We also invent the novel driving method BRD to drive the TN‐type Color‐Sequential display by black field insertion without extra cost. The main features of our TN‐type Color‐Sequential display module include 480 × 272 resolution, TN Type Liquid Crystal (Response Time is less than 8ms by high speed TN LC and low cell gap), wider color gamut and high color expression characteristic (NTSC 96%), and the power consumption of panel is similar to commercial 4 inches TFT‐LCD.
