1 LG screen lcd controller
I have an LCD display, model LM215WF3-SDD3 by LG, that comes from a 2014 iMac. The screen data connector is a 30 pin eDP (embedded DisplayPort) and the backlight power cable has a 10 pin particular connector. According to SDD1 datasheet (can’t find the SDD3 one, hope displays are identical) pin 1 and 10 are not connected, pin 5 and 6 are common anodes and pin 2-4 and 7-9 are the six cathodes for the six LED channels.
Looking around I found controllers with and without inverters and it seems that LED backlight needs inverters too (is it right? thougth only CCFL lights needed them).
The funny thing is that there are no specific controllers for this display model: controllers with inverters have only LVDS connector, controllers with eDP connector don’t have backlight connector and inverters.
After some researchs I found out that LVDS connector has backlight power pins, so can I connect these backlight pins to the screen backlight power? If so, I can buy a generic LCD controller for LED backlights with LVDS connector and buy or build my own cables and use the display, right?
Es esta una buena pregunta?
