What is the model number of the 2880x1800 LCD?

What is the model number of the 2880x1800 LCD in the new mac book pro?

I am trying to purchase the LCD from Samsung (or whoever makes it)

Are you capable of examining the LCD's signals with an oscilloscope? I would like to know if it uses traditional LVDS or embedded display port signalling.

If I can get a panel and make it run, I have a friend that can sell you a 2880x1800 resolution projector.

Update

The LP154WT1 (SJ) (A1) GD has a 30 pin connector, and it looks like there isn't an extra connection for the LED back light. (back light must run through the 30 pin)

The cable looks very similar to the embedded display port cable used on the B131HW02 V0 panel. Since I believe that traditional LVDS signals would require more than 30 pins on this panel, I propose that this new panel must be using eDP.

I am already working on an adapter that could be used with this panel. If I can confirm that this is eDP I should be able to drive this LCD in the next few weeks if I can get my hands on one and the datasheet.

With eDP, this panel would only need 10 DP signal lanes, a hot plug detect, a power supply (probably 2.5V), then the rest of the pins can be used to power the LED backlight.

If anyone wants to experiment, if you can power the panel on (and receive the hot plug detect output) you only need to plug the AUX signal into a display port for it to be detected with the EDID.

Answer this question I have this problem too

Is this a good question?

I am close to getting an adapter into production for a different LG high resolution eDP panel. I have some custom manufactured IPEX cables for it so the signal quality should be very reliable through the adapter (unlike any potential DIY attempts). I will report back when I receive boards and get to test the LCDs.

I made a working adapter for the B131HW02 V0. You just route the DP signals to the correct lines on the eDP panel input and provide power where it needs to go and plug it in to a PC and it works.

I'm still working on getting better cabling though. (not ready to sell any yet) I might try to make an all in one adapter for the various AUO eDP panels. (but they are all different in pinout and voltages)

I am still trying to find info about the high res panels. It is very difficult trying to get information out of companies like LG on their newest LCD panels.

I'm planning on getting my own store setup soon for selling lcd boards.

If I find any new info on these 15.4" displays I will post it here.

But with the 30 pin connector they are most likely display port so once I get my hands on the datasheet and panels I should be able to get them running quickly.

Dear Bill Fleming and 'Bart Son',

Can you please have the great kindness to ping me by email as I want to query you about something about driving this display as an external monitor. Let's take it to this gmail.com address, mikael trash with a dot between the two words.

On what URL:s are the datasheets?

Are there graphics cards today that have Displayport outputs that can drive this display, or would you need a setup using 2x Displayport inputs?

Do you guys post on any other forum also?

Many thanks!

by

With the B131HW02 V0, the datasheet said it takes -0.3V to +3.0V signal logic drive voltage. But the Display Port spec on Wikipedia says the signal voltage is +3.3V. Did you hook them up directly from eDP to DP, or is there something to handle the voltage differences?

How did you drive the LED backlight, using power from the DisplayPort or an external source; if so what voltage and how many amps?

Is this your post over at http://laptopvideo2go.com by any chance?

You should definitely open up a store, that would be great!

It is a bummer that LG is so tight lipped on their newest LCD panels, any chance Samsung is more open? Did you find any info on the Samsung LSN154YL01001 model?

Have you checked out the 3rd Generation iPad LCD panel? I am curious if it is eDP perhaps?

Thanks!

That was my post. I am planning on opening up a store really soon. Hopefully with a proper website and professional email these LCD companies might actually give me information.

Right now all of my free time is spent moving my wife in to my apartment and packing/moving boxes. Also have a lot of parts organizing to do before I can build more circuit boards.

Anyway I will let you guys know when I get my store up.

One of the first things I might have is some kind of eDP board. Problem is right now I don't have any panels to test. I had the AUO but I sent it to a friend. I am also working on getting the newish LG 17" WUXGA 24bit color LED backlight LCDs working with some $30-$35 DVI controller boards. The panels are only around $65, I am trying to target a kit price of around $100. (when I bought my first WUXGA controller kit, the price of the panel and controller was almost $500) I found where to buy that IPAD 2048x1536 panel but it is LVDS probably and i haven't found the spec sheet yet.

It is difficult to find an LVDS board for that resolution or higher. I am trying to find some info on this athena chip that could run high res eDP and LVDS panels, but the chip isnt in production yet and they haven't responded to any inquiries about it. So I probably wont be able to build any really fancy boards until next year. I am hoping that next year I can build a board with 4K support. I think they will have an Athena controller for that by then.

The AUO the backlight requires somewhere around 31V. I used (lots) of AA batteries at first, then my printer's power supply. I have a design for a supply to put on a circuit board, but I haven't built it yet. The chip I had found (forget which exactly) had resistor divider output voltage control, so I should be able to make an adjustable backlight controller board with an analog adjustable nob. The display port signals go straight from the PC into the panel. But you have to hook the correct lanes on one side into the correct opposite lanes on the other side.

by

The LCD panel datasheets aren't very specific about it so you have to kinda guess and hope you get it correct. (the LCD could be labled with signals that aren't swapped or something)

The AUO only uses 2 lane display port though, so that makes it easier to use. The AUX is not swapped, it goes straight through, and is easy to connect since it runs slow on DP 1.1. The other 2 lanes you swap the 0/1 and P/N wires going across. The wires also cross over already on a DP male to male cable.

According to this article there are two LCD Panel models:

LG LP154WT1 and the Samsung LSN154YL01001

Some claim the LG version has a case of image retention, you can use the command found here in terminal to determine the LCD panel model.

Have you had any luck getting your hands on a panel? If so where and for how much, I would love one as well!

In addition, do you have any references for interfacing with the embedded DisplayPort and converting it to a DisplayPort connector? Has anyone managed it with the B131HW02 V0 panel?

This is very exciting!

That would hold true to how Apple has previously contracted LCDs, through 2 different providers. They have done that in the past to prevent lag during initial production and to prevent problems at 1 production facility from interfering with their deadlines.

Hey Bill,

What LG Panel are you using now? What resolution? IPS? Will you open up shop and sell the adapter? Very exciting!

I have a breakout board for the LP154WT1 (SJ) (A1) but still no data sheet to nail down the electrical signals.

I have an LG 12.85" 2560x1700 IPS panel running now.

It is an a-SI TFT AH-IPS.

I plan to start taking orders soon with some sort of store setup, or at least a webpage and a paypal account. (if I have issues installing the store)

I plan on getting some good pictures up later this weekend of the unit working. I even have a special photo-booth for the occasion so maybe I can get some professional looking pictures. (but I don't have a super good camera yet, circuit boards and LCDs cost too much lol)

I am also planning on testing 4k video and nvidia surround on these LCDs soon once I get three of them running.

3 of them in portrait mode = 5100x2560 resolution at about 24". So they can display 5k video from a RED camera, for example. The bezel is small on these in portrait mode so it shouldn't be very noticeable.

I also believe these are the highest resolution you can run at 60 Hz using a display port MST hub. (2 panels in one display port 1.2)

I plan to test one of these and if it works then you could run 3 LCD surround on 2 nvidia 600/700 series cards for example, or a single GPU with dual display ports.

http://www.club-3d.com/index.php/product...

If it works I will eventually be testing 3 of them on a GTX 760 4 GB SLI.

This setup might be too slow to run new games at this resolution though.

I just verified that these do work fine using 3FT, 6FT, and 10FT display port cables from Monoprice. I have verified that Monoprice cables do properly conform to display port specs (particularly power pin connection, IE it is disconnected) however the 10FT is supposed to be out of spec, but it does seem to work fine on this display. I have only tested one 10FT though.

I will be recommending the Monoprice 3FT and 6FT cables with the display kits I will be selling.
