摘要

介绍了一种应用于AM-OLED显示屏的MDDI数据处理芯片。在移动显示领域

MDDI(Mobile Display Digital Interface)因数据连接线少、功耗低、信号传输可靠性高、可有效降低噪声、降低硬件复杂度而得到越来越广泛的应用。所设计的芯片用于240 RGB320的AM-OLED显示屏

支持RGB模式和26万色分辨率。控制显示器的屏幕刷新频率为40~60 Hz。可完全支持MDDI协议。由于输入数据量较大而MDDI为串行接口

芯片的数字输入频率最高可达100 MHz。设计中综合考虑了芯片面积、速率与功耗等方面的限制。经过FPGA验证

该显示电路性能完全满足设计指标要求。

Abstract

A single chip Mobile Display Digital Interface (MDDI) data processing chip was developed for AM-OLED (Active Matrix Organic Light-Emitting Diode) display screen. MDDI is widely used in the mobile display area because of its low-power

small-area and high signal transmission reliability. The design of chip supports 240 RGB320 Dot

260k-color image data

and the refreshing rate of the display screen is 40~60 Hz. Because large amount of input data and the MDDI only support serial data

the working frequency of the circuit can achieve 100 MHz. So this design take all limit factors into consideration

such as the chip area

working frequency and power consumption. FPGA verification illustrates that the design accords with the specification.
