Let's make a "video case"

Postby bluuu » Fri Mar 10, 2017 2:56 pm

Long time ago i found cool thing on aliexpress - very cheap lcd/led screen driver with many features.
called v56
https://www.aliexpress.com/wholesale?ca ... t=tsum+v56

We can connect to it wide range of lcd screens.
I got this:

Brightiness is quite ok 300cd/m2 and a mat panel so will be ok for outdoor use.

more soon ...

good description "how to" connect it together is here:
https://sites.google.com/site/lcd4hobby/

Additional parts:
1. dedicated keypad and IR/Status LED

2. Inverter for powering a backlight of screen (2 outputs in this cause)

3. LVDS cable - 30pin to LCD (2channel, 8 bit in this cause)

4. power supply
We can use 12V Pb aku or a LiPo or other 12V supplier BUT for this 22" screen with backlight we need 3A

How to connect LVDS from lcd side to board, we have to use pinout description from screen manual and board manual and set a valid logic level by jumper:

The last thing - firmware. We must choose correct for screen.

And after that:

You plan a Groundstation in this luggage?
How big is your screen?
