Display module enhancement solutions

When it comes to selecting a specific display to use with your product, it is important to realize that there is no one-size-fits-all solution. Whether you’re designing a user interface for the automotive, medical, appliance, or any other industry, GM Nameplate (GMN) has several different ways of enhancing display modules to suit your unique needs. While display enhancements usually bring to mind a myriad of visual upgrades, these enhancements are also often used to improve the functionality of the device.

Display enhancement and protection solutions 

Some of the most common types of display module enhancement include:

  1. AF or AS coating: Anti-fingerprint (AF) coating and anti-smudge (AS) coating are two of the most common front surface display enhancements utilized today. They help protect the surface from situations where visibility may be hindered with repeated use. Applied via a spray coating, these enhancements are popular in industries where the front surface may be subject to smudging or be repeatedly interacted with and operated by the user.

  2. AR or AG coating: Anti-reflective (AR) coating and anti-glare (AG) coating are both frequently used in industries where visibility is critical. Both can be applied to the front surface of the display module to allow for better visibility in direct sunlight or any other harsh lighting conditions. The coatings boost the apparent luminance and contrast of a display by mitigating the loss of light via reflection or glare.

  3. Decorative cover lens or glass: The front surface of a display module is the first thing a user sees and interacts with, making it an ideal place to have information about the function of the device. Decorating the cover lens or glass is essentially the process of printing colored graphics, logos, or other product information directly onto the rear surface of the lens or glass. It can not only highlight selective parts of the display, but also enhance the look of the module and improve user experience by providing helpful information. This can be employed in a wide range of applications as it can add style and function to any device.

  4. Enhancing the backlight assembly: Inside most display modules is a small strip of LEDs that surround the LCD to illuminate the display. These LEDs are typically housed in a thin metal railing called a light rail and can be enhanced in various ways. The LEDs can be replaced by brighter or dimer LEDs depending on the visibility requirements. Alternatively, a dual-mode light rail can be employed where different forms of lighting, such as night vision, can be implemented by alternating the different kinds of LEDs along the light rail. This kind of enhancement is particularly suited for the military or other outdoor environments where readability is crucial regardless of the ambient lighting.

  5. Tempering cover glass: Tempering glass is a popular enhancement to add strength to the cover glass. It can be done chemically or via heat, allowing the display structure to withstand more force and improve impact resistance. There are also other kinds of material with varying levels of strength that can be used for covering displays, such as Gorilla Glass or PMMA (acrylic). Even bonding the display glass through an optical bonding process can significantly improve impact resistance. This display enhancement technique is particularly suited for devices that may be exposed to a rugged environment or repeated impact.

The different display enhancements and protection solutions are often be mixed and matched depending on the product and performance requirements. Learn more about a few of the different display module enhancements offered by GMN in our video below.
