Abstract

The invention provides an encoding method based on an LVDS (low-voltage differential signaling) interface and a device utilizing the method. The encoding and decoding method based on the LVDS interface includes: acquiring a gray scale of RGB (red, green and blue) image data in to-be-coded data, determining the gray scale as a preset specific gray scale; setting indication marks so that a decoding side can acquire that to-be-decoded data are data corresponding to the preset specific gray scale; changing positions of specific digits of binary numbers corresponding to the RGB image data so that transmission frequency of the RGB image data is reduced after positions are changed. The invention further provides a decoding device based on the LVDS interface.

Description

Technical field [0001] The present invention generally relates to the field of signal processing, and more specifically, to an encoding and decoding method and device 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 to transmit data at high speed, which can realize point-to-point or point-to-multipoint connection , It 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 LCD panels. In the LCD panel, the LVDS interface circuit includes two parts, namely the LVDS output interface circuit (LVDS transmitter) on the driver board side and the LVDS input interface circuit (LVDS receiver) on the LCD panel side. The LVDS transmitter controls the driver board. The RGB (r...
