Driver/Control ICs for Mobile Application

The colorful and large size display continues to challenge the designer, who researches in on-chip Display Data RAM (DDRAM) in the LCD/OLED driver/control ICs, especially for mobile application. In this aIiicle we analyze the special systematic requirement and characteristic of on-chip DDRAM tirstly, and then provide detail ed design considerations from circuit to layout. The DDRAM used in one of our LCD driver/control ICs is shown as example. Index Telms RAM, Display, LCD, OLED
