iPad 3/4 RETINA LCD display interface board - by ROZSNYO

This is it - the true thing!
We have a DP (DisplayPort) to iPad3 LCD interface board - first time available for public orders!

Just connect a Retina display, power supply and feed some video using a DisplayPort input - What is a DisplayPort?
The interface board will present your display as a 2048 x 1536 fixed resolution, 60 Hz display device.

WHY TO RELEASE?
We are a new company focused on video equipment of professional quality and this is sort of a Kickstarter replacement for us - we are unfortunately not US nor UK based so our pitch will not be accepted there. The revenue from the sales of this simple interface will be used for development of a device with HDMI/SDI input which you can use for your camera to assist focusing and view playbacks in native resolution (see the picture below). For owners of the interface board we will make special discounts for that device.

WARNING!
We did reverse engineer the Retina screen last year and all our boards are driving the 12 channel backlit with constant current in each channel separately. Please do not fall for a cheap copy from unskilled designers who use a constant voltage and few resistors - they will not adjust to the thermal changes and will cause your screen to wear out faster.

PRICE & ORDERING
You can have a tested PCB just for $99 + shipping cost of $10 for Europe, $15 elsewhere.
Count-in shipping just once per order and send your payment via PayPal to paypal@rozsnyo.com, ideally with your phone number and any comments you have on shipping (different address, customs value limit, etc).

FAQ

What is the contents of the package?

1 tested interface PCB
2 power plug counterparts
5 power plug contacts
There is no cable included, you must get your own DP cable.
The LCD itself has a non-detachable flex which plugs directly into our interface board.
What voltage does the board need?

The board accepts 7V to 18V, though 12V is recommended.
Have your power supply rated for at least 8W.
What is the polarity of the power plug?

Positive is the top contact (near the plug's latch).
Negative is the bottom one (near the PCB).
Operation manual?

ON button switches between standby mode (red) and operating mode (green).
IN button switches between the two inputs, the number of flashes indicates the input number.
UP/DN button changes the intensity, while there is a change in intensity the LED is orange.
Holding longer speeds up the intensity change and short presses allow fine setting of the intensity.
The board always remembers its state (power state, backlight intensity) on power loss.
The backlit unit is superwised and if there is a fail condition, the LED goes red and the backlit is turned off and on again. In extreme cases it can also oscilate. If your LED does not stay green, there is something wrong with your setup or the PCB.
What is the USB plug for?

Currently for software update only. The toolchain which I use has no support for the ATxmega32A4U microcontroller, so I hacked up the firmware as it would be an ATxmega32A4. However, there was a binary USB bootloader from Atmel, so that got flashed into the processor too and my firmware can call it up.
Firmware update?

Press both IN and ON button to enter bootloader mode. The screen will be powered down and the LED will go orange. Connect via USB to your PC and use Atmel's FLIP utility.
How to use I2C ?

You need to write a firmware specific for your application, please contact us via email.
What screens are supported?

Only the iPad3/iPad4 retina LCD, model LP097QX1.
So far we have tested the SPA1, SPA2, SPC1, SPC2 suffixed models.
Support for other LCD's ?

We have working prototypes for a 2 lane eDP adapter (now with mounting holes and different buttons), which is suitable e.g. for a N116HSE-EA1 11.6" or N133HSE-EA1 13.3" FHD IPS panels.
Will it support MBP retina LCD's ?

We are working on a interface board for MacBook Pro Retina LCD's. Check that site for future updates.
