In this paper, we propose a new data coding method and its circuits for minimizing data transition in text image. The proposed circuits can solve the synchronization problem between input data and output data in the modified LVDS algorithm. And the proposed algorithm is allowed to transmit two data signals through additional serial data coding method in order to minimize the data transition in text image and can reduce the operating frequency to a half. Thus, we can solve EMI(Electro-Magnetic Interface) problem and reduce the power consumption. The simulation results show that the proposed algorithm and circuits can provide an enhanced data transition minimization in text image and solve the synchronization problem between input data and output data.

In this paper, we propose a new signaling method and circuits for interface between the host and LCD (Liquid Crystal Display) controller in the LCD system. The proposed circuits are allowed to transmit two data signals through modified-LVDS circuits and can reduce the operating frequency to a half. Then, we can solve EMI(Electro Magnetic Interference) problem and the power consumption by using differential signaling method. We have compared and analyzed the proposed method and the conventional methods in the power consumption and data rate. In addition, the proposed methods reduce hardware complexity significantly.
