Common problems with LED display screen, You must have some understanding

Whether it's your first encounter with LED displays or choosing the right LED display product for a project, you are likely to encounter many problems and not know how to choose the right LED display for yourself; In order to solve your confusion about LED displays, help you choose a suitable LED display factory to cooperate with, and quickly understand the key issues of LED displays, we have specially compiled the following 7 common questions.

Next, we will answer your core questions about LED display technology, selection, installation, and use in a concise and practical way, so that you can have a clear judgment of the product before entering the procurement process.

1,How does an LED display screen work?

LED display screens are composed of a large number of tiny light emitting diodes (LEDs), which are typically assembled into larger display areas in the form of modules and enclosures. Each pixel is composed of three LEDs (RGB): red, green, and blue, and different colors are displayed by controlling the brightness combination of each LED.

The core operating mechanism of LED display screen includes:

Driver IC needs to allocate current and control brightness

The control system is responsible for image transmission and processing

Splicing the box and module to achieve the final visible area

Because LED is self luminous, with high brightness, color saturation, and long lifespan, it is particularly suitable for applications such as outdoor advertising, commercial displays, stage activities, and control centers.

2,What is the dot pitch of an LED display screen?

The dot pitch of an LED screen refers to the distance between the centers of two adjacent pixels, measured in millimeters (mm), usually labeled as P1.5, P2.5, P3.9......

It directly affects the following three aspects:

Viewing distance

Clarity and detail representation

Overall cost of LED screen

Choose the appropriate point spacing, generally following the principle of: the closer the viewing distance, the smaller the point spacing. Choose the LED display screen that suits you based on the viewing distance.

For example:

P1.2-P2.5: Suitable for close range scenarios such as conference rooms and monitoring centers

P2.5-P4: Suitable for shopping malls, stage LED screens, corporate halls, and street LED displays

P5-P10: Suitable for large outdoor advertising LED screens

Dot spacing is one of the most fundamental and critical parameters when purchasing LED display screens.

3,How to choose the brightness of LED screen?

The brightness of LED screens is usually measured in nits.

Recommended brightness for different usage scenarios. In the practical application of LED display screens, we can refer to the following selection suggestions:

Indoor led display : 600-1200 nits

Semi outdoor/storefront: 2500-5000 nits

Outdoor strong light environment: 5000-10000+nits

The higher the brightness, the higher the cost. Therefore, when choosing, one should choose according to the specific environment and not blindly pursue high brightness.

4,What is the difference between LED display screen and LCD creen?How should we choose?

LED screen and LCD screen are the two most common visual options on the market. What are the differences and how to choose them? It also depends on factors such as project, brightness, size, and lifespan

Project: LED display screen has a wider range of advertising applications, suitable for both indoor and outdoor use; LCD displays are commonly used indoors.

Brightness: LED displays have higher brightness, higher grayscale levels, and brighter colors.

Size: Whether it is an indoor LED display screen or an outdoor LED large screen, it can be customized according to the required size and can be infinitely spliced; The size of the LCD unit is fixed.

Seamless: The LED display screen is completely seamless; LCD has seams (narrow borders)

Lifespan: LED displays have a longer lifespan, reaching over 100000 hours; Compared to LED screens, LCD screens have a relatively shorter lifespan.

Cost: Due to its advantages in usage scenarios and color, LED displays have a higher cost for LCDs (depending on dot pitch and usage scenario)

LED displays have more advantages in commercial displays, stages, outdoor advertising, control centers, and other scenarios, while LCDs are more suitable for budget limited or small-sized display scenarios.

5, Optimal viewing distance for LED display screens,How to judge?

LED display screens usually choose models based on viewing distance, with the number after P representing the dot pitch and viewing distance.

Example:

Indoor LED display screen:

Indoor P1.2 LED display screen → approximately 1.2-50 meters

Indoor P1.5 LED display screen → approximately 1.5-50 meters

Indoor P1.8 LED display screen → approximately 1.8-50 meters

Indoor P2LED display screen → approximately 2-50 meters

Indoor P2.5 screen → approximately 2.5-50 meters

Outdoor LED advertising display screen:

Outdoor P2.5 LED display screen → approximately 2.5-200 meters

Outdoor P3 LED display screen → approximately 3-200 meters

Outdoor P4 LED display screen → approximately 4-200 meters

Outdoor P5 LED display screen → approximately 5-200 meters

Outdoor P6 LED display screen → approximately 6-200 meters

P8 Outdoor Advertising LED Screen - Approximately 8-200 meters

This method can help you quickly confirm whether the LED screen is suitable for your space.

Of course, the selection of LED display screen models also depends on the screen size, such as outdoor lamp post screens. Due to their small size, outdoor LED displays with smaller spacing should be chosen to achieve better viewing effects. If you don't know how to choose your LED display screen, you can consult HSCXLED.

6,What is the difference between indoor and outdoor LED display screens?

The main difference between the two is that:

1, Brightness

Outdoor display screens require 5000-10000 nits

Indoor display screens typically range from 600 to 1200 nits

2, Protection level

Outdoor LED display screens must be waterproof and dustproof (IP65+)

Indoor does not require complex protection

3,Structure and heat dissipation

The outdoor LED advertising large screen box is more sturdy and adaptable to wind, rain, and temperature differences.

The indoor LED display box is thinner and thinner, with a more exquisite appearance.

When making a purchase, it is essential to choose the corresponding model based on the scenario.

7,Is it difficult to maintain LED display screens? Is the cost high in the later stage?

LED display screens can choose from:

Front maintenance (disassembly from the front of the screen)

Rear maintenance (remove from the back of the screen)

Pre maintenance products are the most mainstream in modern applications, especially suitable for wall mounted and embedded installations. The maintenance content usually includes:

Replace module

Replace power supply

Replace the receiving card or cable

Adjust brightness and color consistency

The post production cost of LED displays is not high, but it is recommended to choose a reliable supply chain to avoid frequent maintenance due to poor quality.

summary:

The above 7 questions cover the core questions that the vast majority of users encounter when understanding LED displays, and are also the most critical decision-making factors in procurement.

Understanding the dot pitch, brightness, display technology differences, viewing distance, and maintenance methods of LED displays can help you quickly screen suppliers and determine whether products are suitable for your project.
