A display window allows communication, interaction, and feedback between end users and your product. By selecting the right display window, you ensure optimum conditions for this interaction throughout the lifecycle of your product, in the operating environment that it was developed for. The right solution maximizes usability, performance, and robustness. In addition, a well-designed display window is a key part of the product’s overall design and therefore supports your brand.
So how do you reap these benefits? By focusing on readability, protection, durability, and design. In the following, we will dive a little deeper into each of these key factors.
Enhancing and optimizing the readability of the display is a key priority. End users must be able to read the content (and possibly interact with it) in all lighting conditions that your product will be exposed to. If these conditions are not particularly challenging, a clear display window will often be sufficient. In other applications, you need to take external light sources into account – particularly outdoors, where varying sunlight or glaring streetlights can make it difficult to read and interact with the underlying display.
You can maximize readability by selecting the right base material and surface treatment:
In some operating environments, scratches on the display window are the least of your problems. Your product needs to withstand anything that the environment and your end users may throw at it, and the display window is no exception.
Get a complete overview of the design conditions, and then select a display window that matches them. Again, there are several factors to consider which influence your choice of display window material:

Adequately protecting your product helps you ensure its longevity. This is an important point since durability is another key factor in your selection process. The lifetime durability of your display window should match that of your entire product – and it must handle the same operating conditions as the entire product, so that you don’t have to reinstall a new display window to your device during its lifetime, causing excessive downtime and recurring maintenance costs.
In addition to the environmental factors mentioned above, you need to consider normal user interactions and regular cleaning and maintenance. Again, this has consequences for your choice of material and surface treatment:

In many applications, visual design is a key consideration. The look and feel of a display are often important to the final product, and your display window should be designed and mounted accordingly. If, for example, you need a black panel design or a specific combination of colors for the display content and background, this dictates the color of your display window.
There are also other considerations when designing and manufacturing a customized display window. Often, you might, for example, need to consider the thermal expansion of your chosen material. In extreme temperatures, many materials expand or shrink, and if your design leaves little space for expansion in the joints between components, this is something to be aware of – particularly with large displays.
Whether this (or the many other factors to consider) is relevant or not, of course, depends on the specific application, but you can be sure that we think of everything when designing the display window of your exact project.
