Abstract

The invention discloses a method and a device for achieving dual-mode mobile industry processor interface (MIPI) signals through a bridge chip. The device comprises a low voltage differential signaling (LVDS) to red, green and blue (RGB) module, a mode switch, a video mode data processing module, a command mode data processing module and an interface switch. The device is used for converting an LVDS video signal to a RGB video signal of a data bus interface of the bridge chip in video or command modes according to user setting and for displaying by a liquid crystal module with a MIPI interface. According to the method and the device for achieving the dual-mode MIPI signals through the bridge chip, the achievement is based on the bridge chip, meanwhile, the video and command modes of the bridge chip are compatible, the two modes can be real-timely switched through configuration commands of an upper layer module, appropriate modes can be selected according to system real-time states, and thereby, power consumption and resource expenses can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of display and testing technology of liquid crystal modules, and specifically refers to a method and a device for realizing two-mode MIPI signals through a bridge chip. Background technique [0002] MIPI (Mobile Industry Processor Interface) is the abbreviation of Mobile Industry Processor Interface, an open standard for mobile application processors initiated by the MIPI Alliance including ARM, Samsung, Intel and other companies. In VIDEO mode or COMMAND mode, the bridge chip converts the input signal into MIPI timing interface signal through the internal conversion mechanism. VIDEO mode refers to the mode in which the host transmits to the LCD module using real-time pixel streams and high-speed signal transmission, while COMMAND mode refers to the mode in which commands and data are sent to the controller with display buffer. The VIDEO mode is mainly for the operation of the LCD module without frame buffer (buffer ...
