Common LED Screen Terminologies Every Client Should Know
When clients are planning to install an LED screen, they often hear many technical terms that can feel confusing or overwhelming. Understanding these terms makes decision-making easier and helps clients choose the right solution for their space. This guide explains common LED screen terminologies in clear and simple language, so you know exactly what you’re paying for and why it matters.

Pixel Pitch
Pixel pitch refers to the distance between individual LED pixels on a screen, usually measured in millimeters.
The smaller the pixel pitch, the sharper and clearer the image especially when viewed from a close distance.
Smaller pixel pitch is ideal for indoor spaces, while larger pixel pitch works well for outdoor viewing from far away.
Brightness (Nits)
Brightness is measured in nits and determines how visible the screen is under different lighting conditions.
Indoor LED screens require moderate brightness
Outdoor LED screens need very high brightness to remain clear under sunlight
Choosing the right brightness level ensures comfort and visibility without eye strain.
Resolution
Resolution refers to the total number of pixels that make up the display. Higher resolution means better image quality.
LED screens support advanced resolutions such as HD, 4K, and even 8K, depending on pixel pitch and screen size.
Viewing Angle
Viewing angle describes how clearly content can be seen from the side. A wide viewing angle means viewers can see clear images even when standing off-center.
This is especially important in churches, halls, lounges, and large venues.
Refresh Rate
Refresh rate determines how smoothly motion appears on the screen. A higher refresh rate prevents flickering, especially when filming or displaying fast-moving content.
Professional LED screens always use high refresh rates for comfort and clarity.
Cabinet
A cabinet is the physical panel that houses LED modules. Cabinets are joined together to form the full screen.
High-quality cabinets ensure:
- Structural stability
- Seamless appearance
- Easy maintenance
- Control System
The control system manages what appears on the screen. It allows users to upload, schedule, and control content efficiently.
A reliable control system ensures smooth performance and easy updates.
Understanding LED screen terminologies helps clients make informed choices and avoid unnecessary mistakes. With the right knowledge, investing in an LED screen becomes simpler and more rewarding.
