Color Bleeding Of Chinese Rgb Panels

Recommended Posts

Hi Dann, but between 1K or 2.2K there should be a difference ? in bright / speed or something else ? or is exactly the same ? If you have to choose now a value, would you choose 1K or 2.2K ? Thanks!

Ive only used 1K on all mine but i would think there would be no difference between 1K and 2.2k..

 

Before and after pics..

I have contacted one of the panel suppliers in China LinsLed and sent them a photo graph of the colour bleed. The one below

They responded actually knowing what the problem was.

This is their response.

 

This is  the RCG  problem. You can set it again by the software,and change the parameters.

Attached please find some documents of RCG Parameter Settings

 

They sent me some configuration files for their controller card.  *.RCG files specific to their card

Also on their web site http://www.sbright.net.cn/english/techinfo.asp?id=67 they have this comment about configurations.

Row Blanking time: value set between 10-200000. It is used to fix brightness leak. Set 3000 for double-color display; 200 for full color display. (Real pixel and virtual pixel). If high value is set for Row Blanking time, and with no effects, please check the connection of receiving card and led display, especially whether OE is reversed connected (settings for Led manufactory)

 

 

 

 

So they know about it and call it Brightness leak.

Maybe Lucky knows about these parameters or understands better than me but perhaps it is software fixable.

Hope this makes some sense to someone.

This info is not usable without knowledge how the controller is clocking the panels and how the settings affect

the signaling/timing. Btw they clock the panels with 600hz which is not possible with our controller.

Sorry im a noob but. i did a modifi commodore 64 tape deck to dump real tapes to a pc tap file on commodore 64 lol and load them on the original c64 real time would these resisters work as well http://m.ebay.co.uk/itm/50-x-2-2K-Ohm-0-25w-Carbon-Resistors-1-4w-Resistor-2K2-/230517200151?hash=item35abe55517%3Ag%3AuRUAAOxyXHpSQzU7&_trkparms=pageci%253A97def89f-6639-11e6-9c1f-74dbd1800198%257Cparentrq%253Aa4084db81560a2af57787d13ffff8bb7%257Ciid%253A1
