Thank you Parvo99 for posting your evaluation and photos of the film, I like that in the second photo the ambient light seems bright, washing out the dashboard. I'm glad this enhancement worked out for your application.
For those interested;
This enhancement consisted of adding a clear HEA2000 anti-reflection film to the front of the LCD (reducing total reflection at this layer from about 4% to <1%), adding a clear HEA2000 antireflection film to the back side of the touch panel (again from 4% to <1%), and adding a matte HEA2000 anti-reflection with a soft adhesive to the front side of the touch panel (again from 4% to <1% except with lower specular reflection and higher diffuse reflection due to the matte finish). Reflection of the 2 inner surface of the resistive touch panel remained at 4%.
Total improvement - there was about a 50% drop in total reflection for this display. A better touch panel or alternative could result in between 85% and 95% drop in reflection
To clarify;
1. These are HEA (High Efficiency Antireflection) thin films on PET film substrates, these are not just anti-glare or frosty coatings
2. The material used on the front of the touch panel has a soft adhesive and can be removed and replaced if needed. The other films should be considered permanent. The soft adhesive film potentially could be user installed (though the results would typically be better if I installed them in my filtered air room/class 100 flow bench).
3. If you really want a good looking display use a digitizer instead of a touch panel (you'll need a stylus), or use a NFI or acoustic wave touch panel (or anything without internal relfectance).
Unfortunately the advance sample of HEA2000-matte with soft adhesive has not become a commercial item and the supply of this film is very small and it is not being and may never be produced commercially. However I just ordered a sample run of the HEA2000-clear with soft adhesive which actually should work better for you purpose.
The price for enahncement of a 7" diagon wide screen will be between $100 and $200 depending on what you want to have done (for $200 we could also jack up the backlight brightness); we require a test set for your display that we can drive with either a VGA standard signal or NTSC. And sorry our policy is that our liability is only up to the amount that you pay us, we are not responsible for failure of your display. (We will handle your display with extreme care, but we can not accept liability for a failed display as we expect to recieve everything from new displays which may fail due to infant mortality to used displays which have been mis-handled, poorly packed, and already run for thousands of hours.)
Some screen defect and scratches will go away completely due to our enhancement, other will become more visible. Deep scratches will not go away and may look worse after enhanement.
When the clear soft adhesive HEA2000 material arrives from Asia I'll sell pre-cut 7" sheets for about $15 ea in packs of 3. (or buy a full 500mm x 1000mm sheet for $179.00 plus shipping and cut it yourself )
In addition I suggest you consider a Vikuiti DBEF film for backlight brightness enhancement. This film will give you a 35% to 60% increase in brightness by using an optical trick with polarization and reflection (no added power/passive enhancement).
I am still deciding how to sell these enhancements for your purpose, my company sells to other companies (primarily Marine Computer, In-Flight Entertainment, and recently Cockpit Application) and selling to end users is a new thing we are evaluating.
If you are interested in an enhancement of you LCD please send an e-mail to
MP3Car@FPDSolutions.com. I apolagize in advance if I am slow getting back to you, we are a busy small business with a core of customers we focus on; preference given for multiple displays of the same model or to companies interested in selling/marketing enhanced display from stock.
