My current idea for my in-progress LCD-DSI 17 “ setup is like this :

TOP
------ protective layer (thin abrasion-resistant acrylic or glass)
------ EndLighten
------ LCD
BOTTOM

A few questions:
1. Would you rather use glass or acrylic to protect the EndLighten from scratches? I suppose I could get thinner acrylic (for a similar strength) but glass would be less expensive.
2. Would you leave some space (even very thin) between the protective layer and the EndLighten or not? According to an EndLighten brochure it would be better to leave space for the light to go out but what about the detection?
3. Same question for the EndLighten and the LCD? Someone recommended to use a neoprene layer but should they be as close as possible?

I have noticed there is an abrasion-resistant EndLighten also and it would of course solve the first problem. But is it available in Europe? Has anyone used it? Is it much more expansive than regular EndLighten?

Edit : I forgot this question : I’ll use a kind of u-channel to support the EndLighten and the IR leds. Would you also insert the LCD in a kind of similar channel or put it on the structure directly (will be wood probably) ?

Thank you in advance.

Well, according to some other threads I have read in between, it seems that thick protections are not good for the DSI detection.

I have found this supplier, specialized in protective films for displays of mobile devices: http://www.protectionfilms24.com/

Standard sizes for screens up to 22” are available, as well as custom sizes up to 300 x 550 mm.

Both the Vikuiti™ DQC-160 and Vikuiti™ ARMR200 are said to be compatible with touchscreens. The ARMR200 has a “double reflexive” characteristics. Would it improve or worsen the detection?
