Customer is quite strict with anti-glare. And TUV Singapore ask all the points shall be below 19 at 8HX12H. After studying months,and trying several wave of samples,finally,we chose a kind of anti-glare film imported from USA to equip our LED panel to lower the UGR below 19. 

Weeks later,after certified & approved by TUV Singapore,we are very glad to get batch order from customer. Truly happy to solve problem & bring values to our customers.
