Top 11 LED Screen Suppliers & Helpful Advice ...

2.How much the grayscale? How many bits are allocated to process each color of the screen picture?

You can find more information on our web, so please take a look.

Grayscale is a range of monochromatic shades from black to white. Therefore, a grayscale image contains only shades of gray and no color. In a simple word, the higher the grayscale, the more colors you can choose to display on the screen.

LED display screen with grayscale up to 16-18 bits are made with 16-18 bit color processing and the maximum number of displayable colors up to 18,000 trillion. Besides, this index also influences the brightness of screen.

3.What refresh rate can be presented?

This indicator provides a stable perception of an image. High refresh rate means there is no distortion in dynamic horizontal and vertical stripes when your eyes rove over the screen. And high refresh rate LED display can show refresh rate up to 3,600Hz to 9,600 Hz. 

4.Does the screen have an automatic brightness adjustment system and an automatic system of brightness uniformity?

The automatic brightness adjustment system can provide viewers with comfortable image perception at any weather conditions. Moreover, it can save you a bunch of electricity costs and also prolong the service life to 20-30%.

And, the automatic system of brightness uniformity can ensures up to 99% illumination uniformity across the entire screen surface. 

To check this system availability, you have to demonstrate basic colors including red, green and blue one by one on different brightness levels on the screen.

5.Is there built-in system of color correction and color temperature adjustment?

High-quality LED display will equip with color correction and color temperature adjustment system to allow to adjust color temperature over a wide range from 2,000 to 9,000 K.

6.Can the screen retain a high-quality image with brightness reduction from 100% to 1-2%?

When working in TV studios or applied together with other projection devices LED screens, the LED screen should still perform its full capabilities starting with 1-2% illumination brightness.

7.How can you ensure safe operation in different operating conditions?

The built-in self-monitoring system allows real-time checking of operating temperature, voltage supply and many other characteristics within each LED modules. 

The system will improve safety of the whole screen greatly to prevent unexpected failures and fire.

8.Does the proposed outdoor LED display supplier have qualified production facilities?

The production facilities have direct relevance to the actual product quality. You can ask for whether the plant is equipped with robotics of world-leading brands, test-bench and other equipment as well as aging workshop.

You can also check some certifications such as CE, Rohs, ISO standards.

9.What can the LED screen management system do for you?

If you want to learn more, please visit our website Lucky.

The screen management system should do these things for you:

(1) Playback audio and video content;

(2) Achieve various special effects such as window sizes adjustment, transparency, rotation, and so on.

(3) Simultaneous display of several images.

(4) Can achieve full resolution, enables to display high resolution pictures and videos such as 4K resolution at a rate of 60Hz.

(5) Easy and simple interface for even a novice.

10.How about the fire-resistance ability of LED screen?

You can ask for the actual fire-resistance level of the screen. There will be some special technics such as using polycarbonate with UV stabilizers for resistance or using heat-resisting material for the cabinets.

11.Whether the LED cabinet thin and light-weight?

The thin and light-weight LED cabinet can save storage room and also transportation fees for you. Besides, it can facilitate the installation and maintenance a lot.

Moreover, thin cabinet will improve the heat dissipation to avoid risks of spontaneous combustion and over-heating thus prolonging service life.

12.What services can the outdoor led screen manufacturers provide?

The service you can expect including three parts: technical services, onsite services and post-service project plans.

First, the professional technical services can guide you to deal with all potential technical questions during the rent term. 

Second, on-site service. For example, if you want to rent LED display, there should special staff to set up, operate and disassemble the screen after project.

Third, post-sale services. This part includes reasonable quotation list, timely answers and mature project plans. 

In other word, you can consider this factor from post-sale services, during-sale services and also after-sale services.

In the previous article, we discussed the factors that must be considered when using LED screens, including: the screen area allowed by the user’s venue, the user’s need to achieve the expected playback effect, the environmental brightness requirements for screen brightness, the brightness requirements of red, green, and blue in terms of white composition, the use of pure green tubes for high-end full-color displays, and how to calculate the brightness of LED single tubes. Next, we will provide a detailed introduction to the use of LED electronic screens.

1. Why choose the DVI display interface standard?
(1) The DVI display card interface is a display interface that complies with international computer standards;
(2) Easy installation without opening the chassis;
(3) High graphics memory and strong dynamic image display capability;
(4) Strong software and hardware compatibility;
(5) Supports all operating systems and application software, with flexible and convenient display;
(6) Mass production, low cost, and easy maintenance.
2. Can LED screens be controlled with a laptop? Why?
Can. Laptops must have an independent graphics card and a DVI interface to connect to the control system. Currently, laptops with a DVI interface on the market can be connected to the control system.
3. What is the difference between indoor module full-color LED display screens and SMT full-color screens?
(1) Luminescent part: The display module of the module full-color LED display screen is generally yellow green, and pure green modules are more expensive; Full color SMT screens generally use pure green chips;
(2) Display effect: The module full-color LED display screen has thicker pixel visual perception, lower brightness, and is prone to mosaic phenomenon; The consistency of the full color SMT screen is good, and the brightness is high;
(3) Maintenance: Full color modules are difficult to maintain, and the cost of replacing the entire module is high; Full color SMT is easy to maintain and can be repaired or replaced with a single lamp;
4. The production cycle of outdoor screens is relatively long
(1) Raw material procurement: The procurement cycle for LED tubes is relatively long, especially for imported tube cores, which require an order cycle of 4-6 weeks;
(2) The production process is complex: it requires PCB design, shell making, gluing, and white balance adjustment;
(3) Strict structural requirements: Generally designed as a box, wind, rain, lightning protection, etc. need to be considered.
5. How to help users choose the appropriate LED screen
(1) The need to display content;
(2) Confirmation of visual distance and perspective;
(3) Requirements for screen resolution;
(4) Requirements for installation environment;
(5) Cost control;
6. What is the typical aspect ratio of a display screen?
(1) Image and text screen: determined based on the displayed content;
(2) Video screen: generally 4:3 or close to 4:3; The ideal ratio is 16:9.
(3) How many points can a control system control?
(4) Communication screen A card: single color, dual color 1024 × 64
(5) Communication screen B card: single color: 896 x 512, dual color: 896 x 256
(6) DVI dual color screen: 1280 x 768
