What is a bezel?

April 25, 2022
This article aims to explain the purpose of a bezel, a term you'll often see concerning computer displays. We'll have a quick look at what a bezel is and why screens need them. Different manufacturers use various terminology, making choosing a new display challenging if you're unsure what they mean and how important it is. We hope this clears things up in a fascinating manner.
What is a Bezel?
The bezel around a screen acts in the same manner as a picture frame. As a result, it provides support and protection. In addition, the bezel provides structural integrity to fragile display components.
The derivation of the term bezel goes back to the old French term for the sloping edge of a cutting tool, though it's possible to trace the origins of the root of the word back to ancient names for gemstones with two faces.
The earliest displays that used bezels used cathode ray tubes (CRT). The fundamental physical feature of such displays was the curved display surface that bent around at the edges to form the characteristic bulbous shape. The purpose of the bezel was to obscure the highly curved edges of the tube where any image distortion is highest. The bezel ensured that only the part of the CRT display with a non-distorted image was visible to viewers. As screens became flatter, the manufacturers were able to reduce the size of the bezel.
With the introduction of flat thin screens using liquid crystal displays (LCD) and light-emitting diode (LED) based displays, the purpose of the bezel switched to protecting the screen and structural supporting strength to prevent the screen from twisting or bending.
What is a Bezel's Purpose?
The bezel protects both the display and the user in the case of mobile devices. The glass and plastic-based materials used to manufacture LCD and LED displays can easily chip or break, presenting a risk to anyone handling the display. The bezel provides the user with a safe and tactile handling surface.
The edge of screens is particularly suspectable to cracking and chipping, particularly when placing the device on a hard surface. However, the bezel protects the screen material in everyday use, cushioning gentle impacts and minor shocks.
Does Size Matter?
The shrinking size of mobile devices has led to the minimisation of bezels to maximise the visible screen area without making the devices unwieldy or too large for ergonomic use. This size reduction is particularly important for mobile devices intended to fit comfortably within an average user's hand and slip into the typical pocket.
We can see that reducing bezel size in handheld mobile devices has significant implications for the ergonomics of holding and using the device. For displays such as those found on laptop computers, computer displays, and televisions, the bezel size is more aesthetic as long as it provides the necessary structural strength.
The disadvantage of minimised bezel size is the reduced protection against knocks and shocks, a susceptibility that has given rise to the protective cases market. This protection is particularly important for smaller mobile devices used in rugged environments.
For larger bezel sizes, the bezel can house user controls in the form of buttons and indicator lights.
While the term bezel-less often appears in adverts and marketing materials, all displays require structural support to maintain their physical integrity and protect against knocks and scrapes. Bezel-less actually means minimising the bezel such that it is not noticeable when the screen is in use. At HP, the term Micro-Edge describes the minimised bezel size.
Manufacturers typically used plastics to construct bezels, which were popular due to the combination of low cost and weight that allowed the implementation of complex structural designs. However, the move to bezel-less designs has seen increasing use of metals such as aluminium to offer the required strength with the minimal bezel material.
Benefits for Multi-Monitor Set-ups
One advantage of a minimised bezel size is that it allows the positioning of multiple displays next to each other to provide a much larger display area without the need to invest in a single large display. A minimal bezel size means that the joins between the smaller displays can effectively disappear when viewed from a distance giving the illusion of a single display area. Multiple smaller displays can be more cost-effective and easier to handle than a single display of equivalent size.
