High Speed Serial Interface for Mobile LCD Driver IC

摘要

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 800Mbps for two data channels.
