LTD133EQ1B LCD control board

nicman

I just tore in to a old Lenovo X301 with a LTD133EQ1B LCD Panel in it hoping to build a Magic Mirror.

I just cant find a LCB to it, am i just too much of an amateur or did that device have a funky LCD?

@nicman Hello there!

Have a look at this. I gave quite some information there which I don’t feel like repeating here.
Make sure to check out the links I posted in that thread.

Your screen is a 1-CH, 6-bit, 40 Pin LVDS panel with a 1440x900 resolution. AFAIK the 40 pin connectors include the LED backlight but I have never dealt with one. This site will help you gathering the information you need.

Or google for “LTD133EQ1B controller board” and buy one that tailored to your panel. They cost quite a lot more, though. You most likely find them on eBay, Amazon, or AliExpress.

If you want it dirt cheap there are two possible routes you can go:

Get the cheapest universal LCD controller board you can find, e.g. MT6820-B. It has only VGA input but a HDMI-VGA adapter is like 2-3€.
It need a bit of “frickle” to power the controller and the LED backlight because it dosn’t come barrel jack connector. So wiring/soldering is required. Additional to that you need an extra step-up converter to power the backlight driver. The board runs on 5V while the LED backlight drivers run on 9-30V. The Board uses jumpers to configure it to your panel.
The advantage is you can easily power on/off the screen with a PIR sensor without the need of extra hardware.
You can go for a V53 universal controller board. They cost around 10€ as a set and it is a simple TV controller board. The advantage here is that you simply change the firmware using a USB thumbdrive. The disadvantage is that you need an extra relay with scripts to use it with a PIR sensor. (This is the route I went with)

Both can be found eBay, Amazon, and AliExpress. I generally order from Ali because it is just so much cheaper but that fully denepds on where you live.

There are also some other MT6820 boards with HDMI and DVI but they need the correct firmaware flashed by the seller which raises the price easily to 30€.
