I’m using the second option, because LCD’s boot up time is about 8 sec.

But you have to hook up ground, as i updated your schema. Otherwise the PIR will have zero ground.

Hi guys,

after 6 months I finally completed my mirror. I used IKEA LILLÅNGEN mirror.

Components:

• 14’’ LCD panel LP154W02 (from old HP notebook)
• LVDS controler http://www.ebay.com/itm/LP154W02-LP154WE2-LTN154MT02-B154SW01-V-0-screen-TV-HDMI-controller-board-KIT-/221989744241
• Raspberry pi 3
• HC-SR501 Infrared PIR Motion Sensor Module for Raspberry pi

Because LCDs high consumption I’d like to switching on/off LCD panel, but the boot up time is almost 8 sec, so the PIR is controling only backlight.

Here some photos. If you have any question, feel free to ask :)

Hi Sero,

your inventor has 6 cables, so one of this should be backlight controller. I can’t help you more, you have to measure it by voltmeter or oscilloscope.
