Optical Bonding: The next frontier in display technology

Do you want to know about Optical Bonding?

Using optically clear glue, the cover glass of a display is joined directly to its light-emitting components in the process known as optical bonding. The effectiveness of the display is increased by this bonding, which reduces reflections, boosts contrast, enhances viewing angles, and uses less power by sealing the air spaces between the cover window and the display with glue.

Why is optical bonding necessary for displays?

In addition to offering environmental protection for the display, this procedure can enhance the optical performance of the display by lowering reflections off the display surface. Consider the environment and usage requirements the glass cover will be subjected to before selecting a screen for any project. Without having to enhance the glass glare, this bonding reduces reflection inside these components, improving contrast and improving the panel’s ability to be seen outside or in very bright environments.

What sectors are ideal candidates for optical bonding?

A higher-performance display is needed in these industries because of the severe surroundings, which is why optical bonding is standard in medicinal, transport, and trade areas. This bonding is a good option for companies that frequently utilize displays in high-reliability settings or where shows must be viewed in bright situations. Devices that operate outside or in brightly lit situations are particularly well suited for and significantly more successful when using the optical bonding technique. Standard viewing contexts don’t create a problem, but under specific circumstances, such as outdoor installation, the slight space between the two layers may reduce viewing quality.

Why is optical bonding advantageous?

The LCD’s light reflects off the outside glass and through the gap in a non-optically bonded monitor to produce the image seen on the screen. Refraction is the term for how light is affected when it is stopped and bent as it travels through the crystal of the display’s gap, and a number of the light is returned. As a result of this refraction across the layers, the final image loses clarity and intensity, which reduces brightness and readability. The glass module are bonded and organized to eliminate any gaps and the possibility of light reflection. The screen’s surface receives more light, which results in a brighter image.

• Decrease refraction:

The same theory is in effect when light from an outside source illuminates the screen. An unbounded screen has a cavity between the crystal and other unit that allows for refraction, which reflects incoming light onto the panel and the observer as glare. Light flows through the attached sheets and is slightly immersed into the display when they are joined together. To make screens sunlight viewable, optical bonding is crucial.

• Screens are made more physically robust through optical bonding:

Shock is absorbed by the extra resin layer used in optical bonding. This offers exceptional endurance for usage in industries, public access areas, or other severe situations. Adding a resin bonding layer physically inhibits liquid, and dust intrusion in the glass module is the layer’s most visible advantage. Because of the high production quality, screens in typical conditions don’t have much trouble with water and dust. However, condensation forming amongst the crystal board in settings with considerable temperature variations or varying moisture levels could be a concern.

• Optical bonding prevents condensation:

Screens may fog up due to condensation as a result of moisture entering the midair cavity. Once more, the actual filling of the space stops this issue from occurring. Therefore, optical bonding must be taken into account for any outdoor use as well as for any inside application where stable temperatures aren’t maintained.

• Increased accuracy:

Because the density is preserved via the substrate reasonably rather than being postponed by a cavity, a touch screen with bonding retains a more precise touch response. Bonding increases durability by up to 800%, sunlight readability by up to 400%, and resistance to impacts, vibrations, wetness, heat, and humidity by a factor of five.

• Parallax:

A displacement or difference in an object’s apparent position when seen from two separate lines of sight is known as parallax. Calculating the inclination angle or semi-inclination angle between those two lines is used. The degree of parallax on displays with an air gap is perceptible and gets worse when mounting tape thickness or cover lens specifications change. Parallax is eliminated when light travels through an optical link with a single index of refraction. Another advantage of a touch display product is that the overall stack height is lower as compared to using foam mounting adhesives.

• Vibration Resistance:

This product’s integrity is compromised by the vibrations experienced in aerospace, transportation, and other industrial environments and applications. Its internal components may prematurely fail as a result of vibrations. The cover glass, any additional optical filters, the lens are all secured in place by optical bonding.

Is optical bonding improved the viewing and touch experience for users?

• The internal reflection in glass is eliminated with an optically bonded display. As a result, the contrast is increased, making it easier to see the display in brighter settings. Additionally, by removing internal reflection, a broader viewing angle is created, improving the clarity of the display in larger spaces.
• Everyone will be able to see the glass clearly and without reflection, regardless of whether you have student desks in the front corners of the classroom or have to cram seats up the front edges of the meeting room.
• It lessens parallax, the refraction angle of light that, depending on your line of sight, causes a pen or finger’s actual location on the glass to seem different from the equivalent place.
• Optical bonding reduces the air gap and removes parallax, giving you the most accurate and the most trustworthy and natural experience.

Why is Micron a top leading manufacturer of providing optical bonding?

• The cover glass can be thinner thanks to this procedure because it is held in place by a layer of firm glue. This considerably reduces the display’s weight, making it much lighter and simpler to handle and move. The only proper bonding is optical. Despite claims to the contrary, only an optically bonded display can legitimately be said to be bonded.
• Other techniques are identical to the air bonding procedure in that they use tape to secure the LED cell to the glass, which inevitably results in an air gap. Only an optically bonded can eliminate the air gap and offer these advantages.
• Although optical bonding is frequently used in high-end smartphones, using this technology on larger panels, such as interactive displays, is more challenging. The most cutting-edge optical bonding technology is used and provide optically bonded glass cover.
• We proudly use this bonding technology to create interactive displays with the finest user experience possible. They are more robust, and simpler to handle and move.
• This bonding procedure is no exception to the excellent standard of service we take great pride in providing here at Micron. Applying this bonding to devices internally is a skill our professionals have mastered over time.
