A comprehensive manual on Display Bonding Adhesives
Display bonding adhesives are used to make a wide range of consumer electronics and digital display units. Thanks to advancements in optical bonding, manufacturers can now produce improved displays and enhance the user experience. As our lives get increasingly digitalized, there is a need for more touch screens and display systems to be used. We have smartphones, televisions, tablets, watches, and personal computers that feature fine display systems. However, display technology has led to so many other home appliances like the coffee maker, soda water machines, washing machines, refrigerators, and dishwashers to come with a display unit.
Why we need quality display units
There are various reasons why we need quality display units. Through these display units, we get several information. In home appliances, the display units allow us to understand the working status of the machines. In phones and TVs that have bigger screens, they are used for movies, reading, working, gaming, and so many other purposes. This is why there is a need for display units to come with premium and remarkable quality. Some of the reasons why we need quality display units include:
- Reading should be comfortable.
- It should be able to resist impacts
- They should be able to produce clear visual quality throughout the lifespan of the product.
As there is a need for a display system to maintain its integrity throughout its lifespan, this can be challenging for camera, car, and smartphone displays. This is because these display units are expected to have a continuous non-yellowing appearance despite the presence of climate stresses and sunlight. The need for quality display units made it important for liquid optically clear adhesives (LOCA) to be used in the production of visual display systems in digital devices.
An overview of liquid optically clear adhesives (LOCA)
Liquid optically clear adhesives (LOCA) are needed to provide super high-quality displays that produce superior performances. LOCAs are sophisticated bonding agents that have a high level of flexibility to prevent the thermal stresses that exist between dissimilar bonding materials. This helps to reduce the Mura defects. These are special adhesives that can be adhered excellently to various types and qualities of glass. These adhesives can also be used to protect the liquid crystal display systems from external factors like dust, atmospheric humidity, and so on. The
The industrial importance of display bonding adhesives
Display bonding adhesives are used to create elaborate display bonds that reduce solar reflections by 66%. In ordinary display units, ambient light usually causes abnormal reflections. This natural phenomenon distorts the display unit and makes readability very difficult. This causes serious problems for the user. This technical challenge can be solved with the use of optical adhesives.
The role of display bonding adhesives
A typical display system comes in layers. Thanks to the availability of reliable display bonding adhesives, all of these layers can be held in place securely. The layer is made up of:
- Cover the glass with or without a black mask
- Display adhesive
- Touch panel
- Display adhesive
- Liquid Crystal Display (without or with a bezel)
The display system makes use of the bonding adhesive to fix the cover glass onto the surface (the LCD). The display bonding adhesive is used to prevent condensed water and dust from penetrating the cover glass. In addition, the adhesive also works to enhance the shock resistance factor of the display – this stabilizes the product when it is dropped or knocked to the ground. Additionally, this adhesive comes with a refractive index which has been engineered to minimize solar reflections by about 66%. Display bonding adhesives have revolutionized the consumer electronics market, thanks to their innovative display bonding technology. This display solution is now been used increasingly in both the automotive and the industrial sectors.
Special mechanical properties of display bonding adhesives
Display bonding adhesives help manufacturers of consumer electronics innovate with their monitors, screens, and displays. There are various types of industrial adhesives used in this regard. They are:
- Ambient temperature curable display adhesives
- UV-curable display adhesives
All of these are special display bonding adhesives that offer superior properties and are extremely durable. They can also be used to protect the product against the ingress of moisture while also increasing daily throughput in the facility. Display bonding adhesives are known to feature a wide range of mechanical properties. These properties include:
Low stress: The presence of high stress within the display may lead to cracks and damage. Display bonding adhesives help to minimize the amount of stress present in the display.
Fast curing: Fast curing is a special mechanical property that many industrial adhesives have to help manufacturing facilities increase the daily counts of product units.
Flexibility: Display bonding adhesives offer amazing flexibility functions which help to preserve the top-tier functionality of the display.
High bond strength: Display bonding adhesives are known to offer very strong bond strengths to various collections of substrates such as plastics and glass.
Non-yellowing: The non-yellowing feature of a display is a very important component that guarantees the durability of the product.
Light transmission: The display adhesive should come with an excellent light transmission feature. This superior mechanical property helps to improve the readability of the display unit.
Applications of display bonding adhesives
Display bonding adhesives are used for OLEDs, LCDs, plasma displays, and so on. The bonding agent is used to build these products to improve their performance. Some of the applications of the display bonding adhesives/sealants includes:
- Outdoor signage
- Laptops and PCs
- LCD monitors
- Mobile phones
- Navigation systems
Display bonding adhesives are deployed widely to create various products with displays. The manufacturers also have polymeric compositions. This way, special screens with bendable, rolled, folded, or curved displays and screens can be made. These curved screens and displays usually have superior properties to flat screen displays. The high performance of display bonding adhesives has led to the creation of special 3D display units in various industries such as gaming, medicine, media, advertising, marketing, and many more.
