What is Full Lamination Technology and Advantages of Full Lamination?

Full lamination is also known as non-air-gap technology. Compared with traditional lamination methods, full lamination can be clearly seen in the image reflected from the screen. Touch panel process and components may seem simple, but in fact the touch panel process is varied, in terms of technology, the front-end process and the back-end process are highly variable and growing.

Full-plane lamination technology is to directly glue the panel onto the outer glass (or touch panel), which eliminates the problem of light refraction due to the vacuum in the middle.

Full lamination means that the panel and the touch screen are fully bonded together in a seamless manner using a water-based or optical adhesive. This provides a better display than frame lamination.

The structure of the screen
In terms of the structure of the screen, we can roughly divide the screen into 3 parts, from top to bottom, the protective glass, the touch screen and the display. These three parts need to be laminated. Generally speaking, two laminations are required, one between the protective glass and the touch screen, and the other between the display and the touch screen. According to the way of lamination can be divided into full lamination and frame lamination.

Advantages of full lamination

Full lamination technology removes the air between the screen, which helps to reduce reflections between the display panel and the glass, allowing the screen to look more transparent and enhancing the display. Some phones such as the iPhone 4S, Mi 2, Nexus 7 and Ascend D1 quad-core currently use full lamination technology. Apple's latest iMac also uses full lamination technology.

Another advantage of full lamination technology is that the screen no longer gets dusty. In addition to the increased strength of the touch module due to its close proximity to the panel, full lamination is also more effective in reducing interference with touch signals caused by display panel noise.

Although the advantages of full lamination are huge, the yield rate is relatively low and the consumption and scrap of the surface glass and even the panel during the lamination process due to poor yields will inevitably cause costs to rise, so the control of debubbling and lamination yields will become a more important factor than material costs.

 As the full lamination technology allows the screen display effect to improve significantly, so it will be the next must-have place, and many manufacturers also help to reduce costs and accelerate the improvement of yield rate, I believe that soon the full lamination technology will be popular in most of our mobile phones.
