"I got lucky that it worked "as is" with no driver.
I'm building a laptop around the lattepanda and purchased a screen with a control card. I tried to plug the screen directly 1st and it worked right away!
Samsung LTN156HL01-102 PLS is the reference for the screen
It's one of the 10 best 15 inches screen of the last 5 years. Great contrast !"

He also shared with us the datasheet of this display: http://www.panelook.com/LTN156HL01-102_ ... M6YejjaPk4

And some extra notes:
"There is only some very slight black & white flickering that I notice at startup. But not noticeable when working.
The brightness control works fine too (from linux and windows)
For the flickering, it occured also when using the control card, without the lattepanda“

Hope it will be helpful for everyone here, who is looking for a slightly bigger display for your desktop development environment!

2021-04-04 21:44:12 Wow. That's a surprise.
The eDP panel I have works for both models.
Since there is no detailed info on Alpha vs. Delta, I am afraid that I could not help on this.

That's a telltale sign that LP Delta is having trouble interfacing with your eDP panel.
I have no means to help troubleshooting all kinds of eDP panel issues.
They are not necessarily universally compatible. It may just a simple issue or could be a significant difference.

Pick known to be working is the safer path.

P.S., a nice trick is when ordering the eDP display, ask the selling to get the flex cable for you and ship at the same time. You might get a fairly good discount on the cable/shipping on that.

B173RTN02.2

I found ribbons on aliexpress. You need 30 pin, .5mm pitch, with the correct gold connector on one end (IPEX, I believe), and the bare plated ribbons on the other. I bought one “a” and one “b”. One version has the top side ribbon exposed, other version has the bottom side exposed (relative to the metal connector). So one type reverses the connection order. Not sure which is which and don’t know which one I actually used to get it working, but see the picture and you will know which you need to find. They both came in one package weeks after I ordered them, once again study the pics to get your bearings.
One thing that I do know now, is that pin 30 marked on the LCD must connect to the side of the connector on the latte panda that says “touch”. (See pics again)

So yeah it’s working, no bios changes or drivers etc, happy. My screen does have a few dead pixels curiously in the shape of letters “dB”, I’ll give that to the fact that yeah it’s China, these discount screens didn’t make prime time, so the factory owners brother sells them on Amazon. No big deal for me.
TipA? TipB?

2019-09-16 22:15:43 MISI-DSI is orange (older gen) while eDP is apple (newer gen.)
(Think DDR3 vs DDR4 analogy...)

For LPA, buying an eDP LCD panel is "the" way.

2019-09-16 21:06:31 hello,

how can I resolve the compatibility issue you mentioned below. I have the old generation 7 "LCD and I want to use it.
What can be the solution?

"MIPI display designed for LattePanda 1st genernation is not compatible with eDP display connector designed on Alpha and Delta. This compatibility issue is caused by different CPU architecture and positioning."

2019-07-10 14:48:11 I can not access the datasheet on panelook.
Can some upload the datasheet on these 2 display?

2019-06-30 23:15:40 Theoretically speaking, Alpha and Delta's Intel CPU/SoC eDP port can support up to 3840x2160 @ 60Hz resolution (note this is interface spec only, not actual real life, say gaming, performance.)
Naturally, one has to select the right type of eDP glass (at least, 30pin, eDP, etc. etc.) to achieve such high resolution (4K UHD.)

BTW, at 17.3 inch, the 4K resolution, in its finest details will be a challenge for bare eyes.

2019-03-12 22:58:17 LPA works fine without the monitor attached. Got to use it with hdmi just fine. (glad I averted it being completely dead. It really just took learning how to use the supplied PSU)

Does anyone else have this issue with a monitor attached? Do you just mainly use DC power vs USB-C?
userHeadPic john_mckale
2019-03-11 08:45:26 Try without that eDP LCD glass but just the regular external HDMI monitor and see if the symptom persists. userHeadPic anonymous
2019-03-11 04:32:19 I got my screen and the ribbon cable setup and working!

However after some use, I started getting the USB-C power issues, I finally(and luckily) have been getting it to boot again, but everytime it hits the LP splash screen It shuts off right away.

Any ideas? Probably just drawing too much power?

2019-02-09 23:24:34 I have been looking at this thread no stop for the past few weeks.

I ordered the Samsung 15.6 display from ebay. And still awaiting on the new ribbon cable. I bought one with the gold connector on one end. Not sure how to tell if I got the A or the B relative to the connector.

FOR FUTURE buyers: I originally bought a pack of plain cables without any connector and it will not work for the display. Make sure you get the ones with the gold connectors.

To OOP and revtor,
I am having a bit of a hard time figuring out which side of the ribbon is going to my my "gold finger" or which one is pin 1. Alternatively how did you figure out which one is pin one coming from the monitor? A bit scared to just hook up the display, hail mary, and fry my panda

Really appreciate the write ups and will be sharing my experiences as well.
