Can anybody help with datasheets downloading from panelook.com?

[Роман Хуснутдинов]

Hello, everyone.

Does anybody have an account with spare P-coins on panelook.co to download pdf datasheets. Or, maybe, there is an option to bypass the P-coins system (wich is java-plugin as I see) on this resourse?

I have an account and tried to earn some coins for being able to download few files in the future. But missing datasheets, that I've found in the internet and pics, which I've taken from LCDs I had, were not approved to give me any possibility to earn their damn coins/ download pdfs. For some panels, I'm interested in, I can't find datasheets elsewhere but panelook.com, where it only teases me with its impossibility to get it for free.

Big thanks in advance!

What do you need?  If your google-fu is strong, you don't need panelook usually.

Edit: Also, if you're looking for me to support something new, the answer is no.

I'm looking for a LC490EQL-SHA2 datasheet.

Actually, the whole story is, that I'm working in framing workshop and have experience and access to aluminium mouldings and stands to do the frame and mountings for diy monitors.

I've made a 2k monitor 144hz from controller RT66 from Aliexpress and a spare cheap LCD panel M270DAN02.3. I had to overwhelm some difficulties in finding wires and proper connection of LVDS lines to the controller. But I actually managed to get full operational 144hz jn this panel, though I used only M270DAN02.6 datasheet with frc support.

I'm very interested in this theme, cause I want to offer an option for clients to build their own TV's or monitors using our frames and diy boards from China.

So, basically, the whole magic is about TCON and a separate WLED controller on Innolux panels of this serie. (correct me if I'm wrong). As far as I know, if controller have enough power and bandwith of full 4k 60hz, it also is able to achieve 3440x1440 100hz (115-117 due to advertised bandwidth), 2560x1440 165hz and so on... The only problem, that TCONs can't do this overclock or the panel itself. But as I saw, there are some default TCONs, that actually not so silly in their capabilities. For example, one guy wth AMH a409u, which has V400DK1 ( as forum.level1techs.com says) managed to get 1080p 240 hz and 2k 144hz overclocks: https://youtu.be/W0TBZf90VBI Although, the video doesn't show blurbusters or any other tests.

The whole question for me is:

How to understand whether the stock TCON of panel (for example 6871L-4050A for LC490EQL-SHA2 with 41pin and 51pin (like in stock TCON for M280DGJ-L30) VbyOne connections) is able to actually do 120hz 4k, and this is only the controller problem, which only has 1.4 hdmi interface. By the way, I'm talking about  SONY XBR-49X830C, which can do 120hz 1080p and 4k 60hz (but as far as I know, in UHD mode the controller somehow combines two parts of the screen with a decent postprocessing. The port is definetely hdmi 1.4, cause it's limited in 340 mhz/pixel clock, but somehow the panel can run UHD 60 hz in full RGB, which is meant to be impossible on 1.4 hdmi). Can I wait for the future, where I'd be able to buy controller board with hdmi 2.1 (or DisplPort 1.4) with 4k 120 hz support, with this panel hoping that I'll be able to swith for the new era? By the way, there is an interpolation option in TV, which has to give fake 120hz on 4k, inserting third pics between two rendered. Isn't it a proof, that stock TCON is able to push 4k 120hz, even its not so great in responce time.

Sorry for such a long essay, but this topic really ticles my pickle.

Thank you for your answer!

I actually bought an RT66 as well, but was unable to modify the firmware to go beyond 600MHz pxclk using any input source. 

16L panels can certainly be 4k120 native, but as you've seen, inputs are an issue.  The stock tcons won't support the misaligned halves which is one of the reasons why I had to DIY the tcon.

[Роман Хуснутдинов]

So, It basically means, that I'll have to sell this TV. Unless someone will recompile and produce another TCON, which isn't gonna happen (((

Some last questions to you:

- Some of these Korean monitors, reviewed Wendel from level1tech, (especially Microboard, AMH and Wasabi) have same firmware and OSD menues, which makes me conclude, that they use same controllers. Many of them can be overcloked to higher refresh rates, as far as DP 1.2 allows, but as Wendel showed all of them do a lot of frame skipping presenting an incompability of panels or stock TCONs. Have you met these controller boards? I can't find any info about them, cause there arn't any teardowns of these Korean monitors. They have interesting menu and crosshair option. Are they worth considering and where can they be bought, if you actually know this info?

- I'm pretty sure, that you've tested capabilities of stock M280DGJ-L30 TCON. When I had U28E590D, I wasn't able to get past 70hz on any resolutions. Was that the main board bn91-14986s resrictions, or the stock TCON v390dk1-cls1 is a complete garbage in term of overclocking? I'm considering buying new 28inch kit (especially without mounting plate and, maybe, without second DPtoLVDS board due to insufficient funds recently). How much is it possible to squeeze out of stock v390dk1-cls1 and V390DJ1-CS1 in lower resolutions (considering to pair them with Chinese controller boards)?

Again, thaks a lot. You're the great pioneer and enthusiast. Wish you best luck and new successful projects.

Also, I wanted to ask: I have spare RT66, M280DGj-L30 and tcon from v390dk1-ls1. According your blog "the whole line, 28” TN, 39”/40”/42”/50”/58”MVA all used removable TCONs which appeared to be compatible with each other" I can swap TCONs. Can I use tcon from v390dk1-ls1 on m280dgj-l30 to pair it with RT66 and get fair 120hz in lower resolutions? Can anybody tell me, what these pins on RT66 mean and what are they used for: PWM, ECT, GPIO. Also, I'm planning to leave these pins on V390dk1 TCON free:

7 - SELLVDS - Input signal for LVDS Data Format Selection

26 - 2D/3D - Input signal for 2D/3D Mode Selection

42 - Input signal for Local Dimming Enable

According datasheet, they are odd and can be skipped. Am I right?

Did anybody ordered Wasabi UHD430 i20 with 4k 120hz? Does it mean, that somewhere in Korea or China there already boards with 16lanes 5by1 support and dp1.4 (as it's being used in this one). I only know SVX-4096-120 (https://www.digitalview.com/controllers/svx-4096-120-lcd-controller.html) Is it possible to buy it? If there is anybody, who is waitnig on this monitor, I'd like to ask him to disassemble the monitor and take pictures of panel, Tcon, controllers and all other stuff. I can offer 50 bucks for this information.

Thanks!

I was unable to get more than 70Hz or so out of stock m280 tcon and zero support for 1080p at any speed. Thats why i made my own.

Stock v390 tcon with 4ch lvds could do 37Hz at 4k or 133Hz at 1080.

RT66 can work with either.

Tcons in the innolux family are only partially interchangeable, some things like bit mapping, gamma table, and bias levels are different between them.

I havent seen the insides of those mangos, but i suspect that there are two synchronized scalers, possibly both feeding into a third scaler(or even one of the android based solutions). They also seem to have two frames of latency. Inputs are not meaningfully dp1.4 either, they dont support dsc or hbr3. I'd be interested in pics too if you get them, but only for curiosity.

[ZisWorks]

If you take v390 tcon and put it on m280 you will have inverted image with red/blue swapped and wrong gamma curve.

[Роман Хуснутдинов]

Thanks a lot for your answer. That's a shame that stock tcons are such a crap... But I'll try anyway. What kind of minimal kit can I buy to power M280Dgj-L30 from RT66? I'm running out of budget, so have to choose wisely.
Can I buy just another TCON to get 1080p in 120-240hz and 4k in 60? Or I would need all other stuff aswell to drive your TCON (backlight, dp2lvds and button board with all wires)?

[Роман Хуснутдинов]

Also, I wanted to ask you to upload firmware for rt66 to launch v390dk. I sold my monitor recently and want to use the panel, until the kit will arrive. Can I ask you to give me that firmware or binary code to flash it on bios chip via programmer. I got all the hardware but I'm not able to launch it. Also, I'd like to order the tcon only for this M280DGJ-L30 to upgrade it later (if it would be possible to use it with rt66 and a standard backlight). If it's to complicate, can I ask you to send/sell me the main board from Seiki, which gotta get worthless after the upgrade.
Thank you.
