Driver for samsung ATNA33TP11 OLED panel

I’ve bought an ATNA33TP11 display panel by samsung; here is the datasheet.
Any idea where i can source a driver (eDP) for it?

@nrp , any idea?

Why this panel?

stritcly for coding with the best fonts available to humanity.
there is enough market for this, people who use computers at office; the picture is stunning.

How i found it?

panelook

Criterias

panel_type_main: OLED (paint it black)
inch_low: 1000 (ignore very small panels, I could set it to 13000 I guess)
ppi_low: 325 (>= xhdpi)

Only thing missing there is refresh rate >= 120Hz; let me know if you find something that fits this.

What i have tried so far (hasn’t worked):

DP to EDP 4k 120HZ DIY4K driver board 4K 2K 1080 adapter board For Portable Display

@Arya, any help?

Was there any signs of life from the display?

Is that the correct link? You connected the driver board linked straight to the ATNA33TP11 OLED?

Perhaps I’m blind but the pinout given does not look to match.

“DP to EDP 4k 120HZ DIY4K driver board 4K 2K 1080 adapter board For Portable Display”

ATNA33TP11 datasheet pinout

i did! is it toasted?

can you tell you how i can read the pinouts please?

yes, the link is correct; i just double-checked.

i kinda of see actually.
. so there is no pin for DP_* on the board side which display has a bunch of.
. or NC (pin number 1?) matches on both sides.
. or there is no LCD_* pin on the panel side
so on and so forth… is that the way to read it. they have to match on both sides?

then my question is, how do i feed those pins to a machine (search engine or whatever) and get a match for it. does such thing exist? or do i read every eDP’s pinout, one-by-one?

no sign of life from display

hmm, on secod look; signal names kidda correlate.
3. DP_3NL3_N
4. DP_3PL3_P
… and so on. is that just a different naming? (i wish, lol)

I don’t know, I’m not experienced with working with raw display panels. But it looks like the pinouts do not match, in a way that could be quite bad.

For displays you just match number for number. Pin 1 on one side, to pin 1 on the other side, etc. Sometimes the abbreviations they use are slightly different. Examples are the eDP signal lane pins. You see the display datasheet, pin 3 discription “eDP negative signal lane3” which they abbreviate as “DP_3N”. On the adpater board there is “L3_N” at pin 3, and nothing like “DP_[anything]” on any pins. So that should be just a different abbreviation, “L3_N” meaning Lane3 negative, and the eDP part is assumed. So that would match.

The trouble comes with other pins. Datasheet pin 18 - 20 “Logic and driver ground”. Adapter board pin 18 - 21 “LCD_VDD”… VDD is positive voltage, not ground. wikipedia.org/wiki/VDD_(voltage). It pairs with pin 23 - 26 “LCD_GND” for the ground half of that voltage supply.

So yeah, looks like there is a ground pin going to what should be positive. Quite bad. And there are other pins mis-matched like that. If there isn’t protection against shorts, which, I don’t know, but I wouldn’t think there is. There would be no need to add even the tiniest additional cost or complexity for dead short protection here, since this is an internal connector only used when assembling devices. Accidents like that shouldn’t happen in assembly lines.

Potentially, I did this on my t480s and it blew the backlight fuses and part of the embedded controller. Plugging this into something with the lcd pinout basically shorts the 3.3v and backlight rails to ground. So if those don’t have over-current protection something likely broke.

The pinout is very much not compatible with the de-facto standard lcd ones, you also need different powering circuitry.

Edit: looks like this samsung screen is a little different to the one I got, at least this one has the power circuitry on board and you can just feed it vbat. Could still have some 1.8v instead of 3.3v IO pins but I did not look at it too deeply.

I don’t think there is a way to search like that. Maybe with AI someday.
What you could do is search for terms that might get you to compatable parts. It’s an samsung OLED display. You can try searching with “OLED” and / or “samsung”. Iirc, that’s the issue with OLED displays, they use different pinouts from the other quasi standard LCD pinouts. Samsung I think has their own pinout arrangement. The other, more annoying issue, OLEDs use different voltages Iirc. But if an adapter board similar to the one you linked was made for samsung OLEDs then I would expect it to provide the right voltage, otherwise what’s the point.


we’re rolling :slight_smile:
for anyone interested the eDP-board

now any ideas for how to case this badboy? in my head i’m thinking something akin to iMac G4; basically a very felixible (WLL-E level flexible) arm with a very very minimal casing.
i realise the board will need to be hidden behind the panel somehow so my thinking is to have a casing for the board with attachments to said arm.

obviously i have an idea but i’m having a hard time expressing it :slight_smile: any help?

Thanks mate for the eDp link.

The questions:
A. reagrding the eDp board link:
A1. it says free mini HDMI included
so the other end to the PC is (and can be a normal HDMI)?

A2. There are so many models of those eDp boards, what made you go for ATNA56WR14 ?

B. regarding the Samsung OLED panel:
B1. from where di you source it? (from Germany here)

B2. Does this 4K UHD OLED Display LCD Touchscreen ATNA33TP11 für ASUS ZenBook Flip S 13 UX371E | eBay look like the right panel?

  • As it is transparent (maybe that’s how led panels are?), also confuses with the following statement:
    “Lieferumfang: 1 x LCD Touchscreen Digitizer Assembly (ohne Rahmen)”
    translation:
    “Scope of delivery: 1 x LCD touchscreen digitizer assembly”
    That means, it is just a touchscreen frame and not a display frame?
  • The brand is also listed as FTDLCD and not Samsung
    Pretty confusing.

B3. From where did you buy it? and how does the warranty look like?

Thanks again

hdmi: yes, the gpu (or PC) end is a normal HDMI, at the board’s end it’s mini-HDMI. cable is too short though, you need to figure out an extension for it or if your gpu accepts mini-HDMI just get a longer mini ↔ mini cable.

i sourced everything, board and the panel, from aliexpress (linked in the OP).

i went for this board because it explicitly mentions the panel as supported.

i tried to avoid the touchscreen bits; board apparently does have a module for it but it’s not used; panel doesn’t support touch anyway.

i don’t about the eBay one to be honest but you can look it up on panelook

But on panelook, there is a minimum order quantity and also would require a business email (ie, the domain of the email id) right?

Both of which I cannot satisfy..

It also says: “ Sellers on this platform do not retail to individual” while trying to sign up.

Any suggestions?
