Abstract

The invention provides an encoding and decoding method, device and system based on an LVDS (Low Voltage Differential Signaling) interface, which relates to the field of liquid crystal displays and is invented to avoid electromagnetic interference problem. The encoding method comprises the following steps of obtaining gray scale of RGB (Red Green Blue) image data in data to be encoded; determiningthe gray scale as a preset specific gray scale; setting an indicating identifier so that an decoder can obtain that the data to be decoded is the data corresponding to the preset specific gray scale according to the indicating identifier; and carrying out transposition on specific digits of binary number corresponding to the RGB image data so that the transmission frequency of the RGB image data is reduced after the transposition. The encoding and decoding method, device and system based on the LVDS interface can be used for data transmission of the LVDS interface.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to an encoding and decoding method, device and system based on an LVDS interface. Background technique [0002] LVDS (Low Voltage Differential Signaling, Low Voltage Differential Signaling) interface is a data transmission and interface technology. The core of this technology is to use extremely low voltage swing high-speed differential transmission data, which can realize point-to-point or point-to-multipoint connection , has the characteristics of low power consumption, low bit error rate, low crosstalk and low radiation. [0003] The LVDS interface is a common interface standard for liquid crystal display panels. In the liquid crystal display panel, the LVDS interface circuit includes two parts, namely the LVDS output interface circuit (LVDS transmitter) on the side of the driver board and the LVDS input interface circuit (LVDS receiver) on the side of the LCD panel. The ...
