Frequently Asked Questions
Your Questions Answered
How do you recommend the right LED display configuration for my project?
A: Our technical team creates customized LED‑display configurations based on key project details you share with us. We do not recommend specifications blindly.

Please provide the following core project information so we can match the optimal pixel pitch, brightness, cabinet type, protection grade and maintenance solution for you:
  1. Installation environment: Indoor, outdoor, semi‑outdoor, glass facade / shop‑window; note whether there is direct sunlight exposure.
  2. Project application type: Permanent fixed installation, short‑term rental & stage events, vehicle‑mounted advertising, or custom creative‑shape screen (curved, spherical, transparent, interactive dance‑floor etc.).
  3. Physical dimension: Expected screen width × height, or total display area in square meters. If space is limited, also tell us weight or depth restrictions.
  4. Minimum viewing distance: The closest distance between audiences and the screen. This is critical for selecting suitable pixel pitch.
  5. Special requirements: Front‑only maintenance, curved splicing requirement, transparency rate target, interactive function, power‑supply condition, local certification requirements (CE / ETL / FCC), and your budget range.
Once we receive these details, our team will evaluate and deliver a complete proposal including recommended model list, main technical parameters, estimated power consumption, cabinet size, weight and preliminary quotation within 24 working hours.
If you are unsure about some technical terms, just describe your real‑world scenario in plain language, we will handle the parameter matching work for you.


What is pixel pitch (P) for LED display? How does pixel pitch affect image quality and cost?

A: Pixel pitch is the centre‑to‑centre distance between two adjacent LED lamp beads, measured in millimetres (mm). Smaller pixel pitch means higher pixel density, sharper image details, yet higher overall project cost.


You should select pixel pitch primarily according to your minimum viewing distance, not simply pick the smallest available P‑value. For general reference: optimal viewing distance ≈ pixel pitch ×3 meters. If viewers stand closer than recommended distance, individual lamp dots become visible and ruin visual experience. Cheer offers full pixel‑pitch portfolio from P0.78 fine‑pixel indoor panels up to P10 large‑pitch outdoor advertising screens.

Q2: How to select the correct pixel pitch according to viewing distance?

A: General industry matching rule: minimum viewing distance = pixel pitch × 1000;
  • Close viewing (1–3m): COB P0.78~P1.56, AIO P1.56, TF/HT high-density transparent P2.5;
  • Medium viewing (3–10m): IF indoor P1.95~P2.97, RP rental P1.9~P3.9, CZ creative P2.5;
  • Long-distance outdoor (10m+): FC/FM outdoor P4.44~P10, OM mesh P10.4/P15.6, TT taxi roof P2~P5.

Q3: How to configure screen brightness for indoor, semi-outdoor and fully outdoor environments?

A: 1. Indoor conference/office: 100–600cd adjustable low brightness, avoid eye glare;

2. Semi-outdoor shop transparent window (TF/HT): 2000–5000cd balance light transmission and display effect;

3. All-weather outdoor building wall, taxi roof, stadium: ≥4500cd high brightness anti-sunlight washout, FM outdoor series up to 7000cd for strong light plaza environment.
