When it comes to deciding on the specific display to use with your product, it is important to realize that no one size fits all. Whether you’re designing a user interface for the automotive, medical, appliance or any other industry, GM Nameplate (GMN) has several different ways to enhance 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.

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, which makes 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 information about the product directly onto the rear surface of the lens or glass. It can not only help highlight parts of the display, but also enhance the look of the module and make for a better user interface 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 of many display modules, there 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 especially important in 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, which can allow 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 useful for devices that may be exposed to a rugged environment or repeated impact.

The different display enhancements can often be mixed and matched depending on the product and performance requirements.
