LVDS CABLE , EDP CABLE
I hope this has been useful to you and the main message here is that LVDS need not be confusing or expensive so long as you get the right advice from people who know this product type well and have your best interests in mind.
If you work with flat screens or integrate them into the products you manufacture you will have used low-voltage differential signalling (LVDS) cables.
LVDS was introduced in 1994, and has become popular in products such as LCD-TVs, automotive infotainment systems, industrial cameras and machine vision, notebook and tablet, communications systems
The cables supplied by monitor and touch screen manufacturers are (if you get one supplied) often unusable because of the PCB you need to connect to may have different headers, or simply they are the wrong length and/or pin-out you need.
Recently I have seen a great variation in price and configurations from simple to very complex assemblies. The following is a simple guide to explain the fundamentals of the cables used, and to help you understand what you need to know when asking for bespoke Cable Assemblies.
The LVDS connector is a bit of a confusing name, too, as LVDS really refers to the way the data is transferred rather than the connector itself. So, for example, the connector pitch can be anywhere from 0.5mm through to 1.25mm depending on the device connector.
Connector Type
The main connector manufactures mostly have a range to suit. However, I typically see Molex, Hirose, I-Pex and JAE & JST as the most used and copied.
Cable Type
The typical cable use is a twisted pair cable of around 28 – 32 AWG. However, FCC / FPC cable is very common especially in use with devices such as Laptops or devices where space is of a premium.
The connectors will be anywhere from 20W through to 80W circuits. However, typically you’ll see 20W as the most common.
Costs
With so many choices the cost will vary depending on the type and configuration you need. The good news is that if you have a requirement for a bespoke LVDS Cable then they are very easy to replicate and the costs should not be that high.
A word of warning: because so many people are confused and unsure about what they need (or who to go to for the cable they need manufactured) I have seen some very high prices. I’d urge you to speak directly to the companies, like ours, that will not take advantage of your situation. The costs should be in-line with most other similar assemblies.
