Dual block truncation coding for overdriving of full HD LCD driver

This paper presents an image coding method for overdriving of 10bit Full HD LCD display considering the chip size of TCON (Timing Controller) and real-time operation. The proposed method is an adaptive scheme of AM-BTC (Absolute Moment Block Truncation Coding). It splits a sample block into two sub blocks considering the color level distribution of the sample block and applies AM-BTC to each sub blocks. Experimental results show that the proposed method is superior to the conventional method in both objective and subjective visual quality.
