Interactive Flat Panels generally have two screens, the upper touch screen, the lower display; and the way to stick the upper and lower screens together is the bonding method. There are three types of  bonding methods: ：Optical bonding, Zero bonding and Air bonding.
 

Which screen bonding technology is good?

We can harshly compare the three bonding methods.

Cost: Optical bonding > Zero bonding > Air bonding;Experience: Optical bonding > Zero bonding > Air bonding
 

From the comparison, we can conclude that optical bonding has the best experience but the highest cost. High-end panels and LCD are all optical bonding. Although the air bonding is not as good as optical bonding, it has the lowest cost and is cost-effective. And zero bonding is between optical bonding and air bonding.Realistically, air bonding would be great. And only from the perspective of pursuing the extreme fever, those who are not bad money can choose optical bonding.
 

The following is a careful analysis of the three bonding methods using the basic principles of the process, as well as the pros and cons.

Process: Use double-sided tape to stick the touch screen and LCD screen on all four sides, the middle of the two screens is empty, there is air.

Pros: Simple process, mainly paste a circle of glue, not easy to paste bad, so the assembly cost is low. The two screens are separated, one bad does not affect the other, so the maintenance cost is also low.

Cons: There is air in between the two screens, so it is easy to reflect and may get into dust. Since the two screens are separated, the light from the display will be filtered one way, and the visual effect is poor.

Overall, if you are looking for a cheap option, you can choose a flat panel with this bonding process!
 

2. Zero bonding 

Process: Use glue to stick the touch pad and LCD screen on all sides, the middle of the two screens is transparent medium, not air.

Pros: Reflections are dramatically reduced, better display, thin body, no dust.
 

As a well-known display device manufacturer, in order to allow customers to operate the writing experience is more excellent, OKV's interactive flat panels are mostly used in this way of bonding, the use of "zero bonding process". On the one hand, greatly reduce the gap between the glass and the LCD screen, thus avoiding light refraction affecting the display effect, effectively improve the screen display effect, do not miss any details in the screen, visual more transparent; on the other hand, so that you can touch the touch writing more natural, can restore the real handwriting experience, pen more accurate, to effectively meet the needs of creative painting, calligraphy design and other scenarios in the field of application.

3. Optical bonding

Process: Use water glue or transparent optical glue to stick the touch screen and display together completely, just like a screen.

Pros: Reflections are greatly reduced, the display is bright and effective, the body is thin, does not enter the gray, and the bezel is narrower.

Cons: High defective rate, so high cost.

From the practicality and cost-effective point of view: in fact, the pursuit of practicality with zero bonding is enough. The pursuit of the ultimate experience, choose the optical bonding.And OKV also has a more skillful production line for the production of Optical bonding interactive flat panels, to provide you with high-end display equipment.
 

Comprehensive comparison and analysis of the above can be concluded : Optical bonding process is the most advanced!

At present, the Optical bonding technology is mainly in the small size products in a wide range of applications, including cell phones, flat panel is currently basically the use of the Optical bonding technology; in the field of large-size display, the application of the Optical bonding technology has not yet formed a scale, the main reason is that the process is complex, the production environment requirements are very high, the production yields are low, the cost of rework is high, which is a series of factors affecting the application of the Optical bonding technology in the large-size screen.But it can be predicted that, with the wide application of Optical bonding technology, Optical bonding will become the mainstream of technology in the future, and Optical bonding interactive flat panel will also become the main application of the product!
