How to Improve Display Durability, Visibility, and User Experience

Why Should You Improve Display Durability?

Once a display design meets visual and user experience requirements, it is critical to ensure that it performs optimally throughout the device's life. Displays are frequently subjected to heavy use, drop shock, sudden impact, extreme weather, a variety of potential contaminants, and other hazards, all of which can damage essential components and cause malfunction.

There are many enhancements to help display weather impact and heavy use without impeding function, ranging from strengthening the housing to tempering the cover glass. This is especially true for devices used in eMobility, medical, aerospace, or defense applications, where malfunction or device failure can jeopardize user safety.

At Reshine Display, some of the most common types of display module durability enhancement include:

1. Optimizing Bezels and Enclosures:

The durability of housings and enclosed displays can be greatly influenced by different types of plastic and metal. Materials with high impact resistance and strength, such as acrylonitrile butadiene styrene (ABS) and engineered polymers like polyphenylsulfone (PPSU), make for long-lasting display enclosures. Our display design experts can guide new or existing housings and bezel designs that optimize material selection and display protection, even for bezel-less frames.

2. LOCA Bonding:

The method used to connect display module components can have a significant impact on durability. Liquid Optical Clear Adhesive (LOCA) bonding is the most durable and effective bonding technology available. Because the display layers are bonded together with a liquid adhesive rather than a framed air gap or adhesive tape, it resists extreme temperatures and condensation and improves overall impact strength significantly. This bonding technology is especially useful for devices that may be subjected to a harsh environment or heavy use regularly, such as consumer electronics.

3. Gasketing and Sealing:

Display gaskets are flexible and resilient, and they are frequently used to toughen screens and improve durability. Front frame gaskets and seals, foam adhesive tapes and seals, bezel bonding seals, foam spacers, cushions, or dampers, touch display mount tapes, housing seals, and other solutions are examples of these. They absorb shock and vibration to prevent screen cracking and dust ingress, as well as allow for heat dissipation and acoustic or mechanical energy damping. Gaskets also shield sensitive internal display electronics from dust, water, heat, oil, and other contaminants, ensuring long-term optical clarity. For greater efficiency, easier assembly, and even better durability, Reshine Display can integrate multiple engineered materials and thermal technologies into single, efficient display gasket solutions.

4. Cover Glass Tempering:

Tempering glass is a popular enhancement that uses heat or chemicals to increase the strength of the cover glass by changing the compression and tension of the glass. This allows display structures to withstand more force and improves impact resistance significantly. Gorilla GlassTM or DragontrailTM are both tempered aluminosilicate glass that is commonly used for consumer devices that require the highest level of impact protection, depending on the thickness and strength requirements for the cover glass.

5. Display Protection Films:

Display protection films provide an optically clear barrier to improve display resistance to scratches, impact, UV, and water while retaining maximum optical transmittance. Long-term or short-term use protective films are available. Long-term applications are designed to protect sensitive components such as cover glass, screens, and other surfaces from scratching or cracking during frequent and repeated use. Short-term applications protect screens during the manufacturing, build, and sales processes before being removed by the owner. Depending on the level of protection required, there are numerous options available, including anti-shatter and cover glass reinforcement solutions.

Reshine Display has decades of experience supplying various display technologies to OEMs and Tier 1 partners in a wide range of industries. We can streamline your supply chain and combine multiple display enhancements into a single integrated display solution thanks to our supplier relationships and access to advanced engineered materials.

Why should you improve display visibility and user experience?

By increasing sunlight readability, maximizing display vivacity and clarity, and optimizing power efficiency by minimizing display light leak loss, visual display enhancements improve user experience, customer satisfaction, and market adoption.

The following are some of the most common types of display module enhancements to improve visibility and user experience.

1. AF or AS Coating:

Two of the most common front surface display enhancements used today are anti-fingerprint (AF) coating and anti-smudge (AS) coating. These coatings protect surfaces whose visibility deteriorates over time. These enhancements, which are applied via spray coating, protect displays in applications where the front surface is subject to oil and contaminant deposits from repeated user touch, interaction, and operation.

2. Anti-reflective (AR) or anti-glare (AG) coating:

Anti-reflective (AR) coating and anti-glare (AG) coating are commonly used in outdoor applications or those with varying light exposure. Mitigating glare and reflection is critical in industries where visibility is critical and users are exposed to both natural and artificial light, such as the automotive or agricultural industries. Both are applied to the display's front surface to improve visibility in direct sunlight or other harsh lighting conditions. These coatings improve a display's apparent luminance and contrast by reducing light loss due to reflection or glare. Users notice more vibrant images in a variety of settings.

3. Decorative Cover Lens or Glass:

Because the front surface of a display module is the first thing a user sees, it is an excellent location for device information, instruction, and function. Printing colored graphics, logos, or other notes directly onto the back surface of the cover lens or glass is what decorating entails. These markings, which combine form and function, can be designed to highlight specific areas of the display, improve display aesthetics, indicate warnings, or promote brands. Because of its versatility, this process is suitable for a wide range of applications.

4. Improving the Backlight Assembly:

To illuminate the display, many display modules include a small strip of light-emitting diodes (LEDs) that surround the LCD. These LEDs are typically housed in a thin metal railing known as a light rail, which can be enhanced in a variety of ways. Depending on the visibility requirements, LEDs can be replaced with brighter or dimmer LEDs. Boyd can also install a dual-mode light rail, which switches between LED types to include multiple lighting forms along the same light rail. Brightness enhancement films improve the display's viewing angle and recycle backlighting light toward the user, improving vivacity, visibility, and backlight efficiency. A small strip of light-emitting diodes is included in many display modules.

5. Reflector Films:

Reflector films are integrated into displays to improve efficiency and brightness by reducing waste light directed to the display's sides or back. Reflector films reflect light through the display, directing all light generated by the display module toward the viewer. More light reaching the user improves energy efficiency, vibrancy, and color accuracy.

6. Optically Clear Adhesives:

Use refractive index-matched optically clear adhesives (OCAs) to bond display module components together while minimizing refractive loss. The optically clear adhesive ensures a consistent, thin bond across the display while maintaining maximum clarity. OCAs are optimized to match the refractive index of display module components, maximizing light transition to the user and resulting in improved display contrast, vibrancy, and vivacity.

Depending on the product's visual and performance requirements, different visual and user experience display enhancements can be mixed and matched.
