Embodiment Construction

[0021] The core idea of ​​the present invention is that after receiving the DP signal through the DisplayPort (referred to as DP) interface terminal, the DP signal is converted into a low voltage differential signal (Low Voltage Differential Signaling, LVDS), and the DP signal is realized through the LVDS signal transmission mode. interface function.

[0022] The present invention makes full use of the existing TV signal processing technology, and realizes the DP interface function through the LVDS signal transmission mode under the condition of keeping the existing TV signal processing system as little as possible. The improvement of the present invention includes two parts, one is to increase the side-end DP circuit board 100 for receiving DP signals and converting DP signals into LVDS signals, please refer to figure 1 shown; at the same time, appropriate improvements have been made to the existing TV signal processing system, please refer to figure 2 The structure schemat...

Abstract

The invention discloses a television which realizes the DisplayPort (DP for short) interface function and a realization method of the DP interface function, the television comprises a side end DP circuit board and a television main signal circuit board; the side end DP circuit board comprises a DP interface terminal for receiving DP signals; a first data format converter which is connected with the DP interface terminal and used for converting the DP signals to LVDS signals by carrying out the data format conversion; and one or two LVDS interfaces which are connected with output ends of the first data format converter and used for transmitting the LVDS signals; the television main signal circuit board comprises one or two LVDS interfaces for receiving the LVDS signals which are transmitted by the side end DP circuit board, input ends of the LVDS interfaces are connected with the output ends of the LVDS interfaces in the side end DP circuit board through AWG shielding connecting wires;and a second data format converter which is used for converting the LVDS signals to digital video signals or RGB signals by carrying out the data format conversion. The invention simply realizes the DP interface function, thereby having broad application prospects.

Description

technical field [0001] The invention relates to signal conversion and processing technology, in particular to a method for realizing DisplayPort (abbreviated as DP) interface function by using LVDS signal transmission, and a TV set using the method. Background technique [0002] The DisplayPort interface is an open interface standard for all display devices released by the Video Electronics Standard Association (VESA) in May 2006. Like the High-Definition Multimedia Interface (HDMI), DisplayPort supports audio and video signals to share a cable transmission, corresponding to a variety of high-quality digital audio, and the DisplayPort standard adopts a lower working voltage embedded clock structure, thereby reducing electromagnetic interference while improving compatibility. Due to the micro-packet architecture, DisplayPort can provide up to 10.8Gb / s bandwidth (in comparison, the latest HDMI1.3 specification only provides 10.2Gb / s bandwidth), and a DisplayPort cable can sup...
