Abstract :
A high speed serial interface is proposed for a mobile VGA-resolution TFT-LCD driver IC. This high speed serial interface is intended to replace the legacy RGB interface for the LCD driver IC´s. The transmission channel consists of one clock and two data differential lines, and thereby we can reduce the number of signal lines going through the hinge of a mobile phone from 28 down to 6. The simple synchronization encoding scheme facilitates the pixel synchronization. All channels conform to sub low-voltage differential signaling (SubLVDS) convention. The total data transfer rate can be up to 800 Mbps for two data channels.
