Extending the internal cables in TFT screens

**_dopehead_** · 02-13-2005, 05:41 PM

Has anyone attempted to make the ribbon and backlight wires longer from the LCD screen to the controller internally in the case ? I want to use the module about 3 inches from the controller itself.

Backlight cables can be extended without problems, only take care since the cables between inverter and CCFL use high voltages, so use proper cabling.

Extending the other cables is somewhat more difficult: Depending on the cables used you have to solder it yourself. There are some extensioncables available, or you can make one yourself, but it requires some soldering skills.

I did it once myself (to get an old TFT on a overhead projector, so it's now a beamer). A micro soldering iron is advised, since I had to solder 20 wires on a 1 cm width cable (0.5mm connectors.. so its small)

The regular FFC extensioncables can be found on some DIY-beamersites, like www.lumenlab.com and/or www.diybuildergroup.com

The connectors and cables itself can be ordered at Farnell. (dunno about USA shippings). My screen needed a 20pins 0.5mm dotpitch cable/connector, which my local electronics shop ordered for me at Farnell ( www.farnell.com ), productno 3078413 (connector) and 3295035 (cable)
