In our newly released IQTouch HC900Pro all-in-one display，there is a new technology supported - Optical Bonding. The common bonding technology of interactive flat panel includes optical bonding, zero bonding and air bonding. Both air bonding and zero bonding have a gap which is full of air between LCD panel and touch screen. Along with dust entering the gap, it may cause blurred screen. However, optical bonding is the use of an optical-grade adhesive to glue a glass to the top surface of a display, which makes sure absolute vacuum and no air left between the LCD panel and the touch screen. It not only brings unparalleled readability, but also extreme smoothness of writing.
On the basic of 4K resolution, the screen with optical bonding has higher brightness, contrast and range, which presents you high quality video and gives you immersive visual experience than before. Besides, the content on the screen is still clear when viewed from the side with optical bonding. It supports real 178 view angle to deal with the users unable to see the content of screen when they are sitting at front sides or at the corner of meeting room. No matter where you sit in the classroom, you can clearly see the screen.
In terms of writing experience, optical bonding makes more accurate touch response with zero deviation. Almost like you are writing on the paper. With 0.5 mm accuracy, and 1.5mm touch height, brings writing experience smoother than ever. It also has intelligent gesture recognition such as single finger to drag and drop, two fingers to zoom, five fingers to roam and full palm to erase. What can't be ignored is that optical bonding has greater physical durability and impact resistance. It protects the screen from damage by rough transportation and violent damage, which avoid the situation of fragile screen.
What I mentioned above is all the benefits optical bonding brings to HC900Pro. However, the advantages of HC900Pro are not just these. For more details, please see the next article or view our website https://www.iqboard.net/.
