Samsung TV Diffusers backlight assembly

Hi,

I disassembly the TV (model Samsung ua40j5500) screen and diffusers in order to access the LED strips.

I didn't unfortunately marked the diffusers (there are x2) and have no idea which side of each is upward (face to the screen)

The rigid diffuser got crispy side and smooth side (which side is up please) and the flexy diffuser got glossy side and non glossy side (who should side is up please)

Highly appreciate your support

Thank you, Roni
