Factors to Consider When Choosing LED Display Technologies

Now that you know about the types of LED displays, you need to take note of some factors before you eventually choose the screen you want. 

Choosing the right LED display technology for your needs can take time and effort. It would be best if you considered these factors to avoid setting yourself up for trouble. These factors include

1. Pixel Pitch

Pixel pitch is the distance between two pixels on display and measures in millimeters. It greatly influences the resolution and image quality of the screen. The viewing distance available will be a pointer to the pixel pitch to opt for. 

A smaller pixel pitch indicates many pixels per unit area and will result in higher resolution and image quality. On the other hand, a higher pixel pitch indicates fewer pixels per unit area and will produce lower-quality images.

2. Viewing Angle

The maximum angle you can view the screen without losing an accurate display is the viewing angle. Wider viewing angles are suited for environments where many people view the screen simultaneously. 

The vertical viewing distance is as important as the horizontal viewing angle, so check it before completing the sale. Displays with wider viewing angles may be more expensive, but they will give you better display resolution and picture quality.

3. Brightness

The standard unit for measuring brightness is nits, which indicates the intensity of light the screen emits. Outdoor displays need a higher brightness to stay visible in different lighting conditions.

Excessive brightness levels can cause strain to the eyes. So before you choose a screen, ensure the brightness is adjustable to meet each viewing requirement. With the brightness level, your screen will remain legible and comfortable.

4. Contrast Ratio

The contrast ratio is the difference between the screen’s brightest and darkest parts. A higher contrast ratio will give top-notch picture quality while ensuring that black remains black and white remains white. Suppose the image quality is a key factor driving you to purchase a screen. In that case, you must confirm its contrast ratio early.
