Hello, everyone. I haven't been here fore long time.
Maybe many people are interested in making retina wacom tablet.
But as you know there was a big problem to tear down the LCD panel, since the back side of the retina panel is all aluminium..
Anyway I succeed to make it, so i wanna share it.
Let me start.
This shows the difficulty of tearing down. The aluminium covers all area of the back side..
As a first step, let's unflip the pcb board. It can be done easily by knife.
BUT, I got a problem... maybe my hand is a big problem
As you can see the picture, I cut the one FPC line (LED) by mistake!!!!!!!!
Always, the starting point is very important..
Anyway, One of my friend fixed this by soldering Pb on FPC lines.
And this panel has 2 lanes of LED one is near the PCB board, another is on the opposite.
At first time, I did not know how to cut the aluminium. I decided to clean all the tapes first.
I forgot to take picture, sorry.
Anyway, after removing all tapes on the panel, you can take the back aluminium plate.
From the bottom side ( the opposite of the PCB board), with knife or something sharp, you can detach the LED on that side.
And then with careful concern, you can take the plate out.
Once you take the plate, we can cut it by dremel or something. (you should have something to cut the aluminium.)
So, just leave the minimum area to protect LED backlight and attach it again.
After then, it is straightforward.
First I need to buy vga controller.
I bought this vga controller from "http://abusemark.com/store/
Since it is based on eDP with low power consumption, the board is very tiny. Looks cute.
If you have a graphic card that has DP port, you can run the panel. It is retina!! 2048x1536 resolution in 9.7" !!
Now, to block the light emission, I did taping.
Let's look at cute PTZ630. I cut the cover by laser.
Before cutting the cover, let me test the panel with tablet.
It works perfect. No jitter at all at 57Hz.
There are two main reasons for no jitter, i think.
First is that the panel is quite thin, so the signal of pen can reach to the wacom tablet board easily.
Second is that the PCB board of LCD is well insulated(?) from EMS. Look at the photo with beautiful tiny metal box.
Let me move to cut the cover. With careful concern, mark the point to cut.
And with laser cutting, you can easily cut the cover. (I do not know the price in other countries, but in korea laser cutting is very cheap.)
Since the panel is too thin, I added some thick material.
To hold LCD tight, i used little screw.
Here is the vga controller. I drilled on the bottom of tablet so the FPC eDP cable coming from the bottom.
And I folded the eDP cable to have nice(?) shape.
And the board is run by USB charger with microUSB connector.
And then, I bought 1.65T tempered glass, and painted with black on inactive area.
And attached to LCD with 3M tape which is strong enough at high temperature.
Here is the one more shot of the bottom.
Can you feel the high resolution?
Test with pen. I wrote down something.
