序章
の LED表示 has won wide recognition in the market for its excellent display effect, flexible application mode, and long service life.
However, in the face of a wide range of LED display products on the market, it is often difficult for consumers to judge their quality. Some low-quality products not only affect the viewing experience but also have potential safety hazards. Therefore, it is particularly important to know how to buy high-quality LED displays.
This article will tell you how to buy a high-quality LED display. Let’s take a look.
1. Clarify needs and budgets
Before purchasing high-quality LED displays, it is critical to clarify the demand and budget. This not only helps to narrow the selection but also ensures that the final product you choose fully meets your expectations and actual needs.
初めに, you need to clarify the main purpose of the LED display. Different usage scenarios have different requirements for the display. For example, commercial advertisements may need high-brightness and wide-angle displays to attract the attention of pedestrians.
Home theaters may pay more attention to color reproduction and viewing comfort, while stadiums may need oversized and high refresh rate displays to present clear and smooth game pictures.
第二に、 consider parameters such as screen size, resolution, and brightness. The screen size should be determined according to the actual use environment and viewing distance. The resolution determines the clarity of the picture, and the brightness is related to the performance of the display under different light conditions.
After clarifying the requirements, a reasonable budget needs to be set next. The budget not only determines the grade and brand of the products you can buy but also helps you stay rational in the actual purchase process and avoid exceeding the affordability.
When setting the budget, in addition to the price of the display screen itself, additional costs such as installation, transportation, and maintenance should also be considered. At the same time, we should understand the importance of cost performance. Don’t blindly pursue low-priced or high-priced products, but choose the most suitable products according to actual needs.
ついに, take into consideration the demand and budget to determine a general purchase direction and scope. This helps you to be more targeted in the subsequent product selection process and avoid being disturbed by irrelevant information.
2. Pay attention to product parameters and technical indicators
When purchasing high-quality LED displays, it is crucial to pay attention to product parameters and technical indicators. These parameters and indicators not only reflect the performance and quality of the display but also are directly related to your user experience and viewing effect.
The following are some key product parameters and technical indicators for your reference when purchasing:
Pixel density (PPI): This is like the clarity of our mobile phone screen. The higher the PPI, the more pixels on the screen, and the clearer the content displayed, just like it is more comfortable for us to watch high-definition movies than blurred movies.
輝度： Brightness is how bright the screen is. If the screen brightness is not enough, you can’t see the content clearly on the screen in a sunny place. Therefore, if you plan to use the display outdoors, you should choose high brightness.
Perspective: The perspective is that we can see the scope of the content from different angles. The larger the perspective, the more it means that no matter where we stand, we can see the content on the screen clearly.
Color reproduction: This parameter determines whether the color displayed on the screen is real. For example, if the red color displayed on a screen is too bright or too dim, its color reproduction is not good.
Refresh rate: The refresh rate determines how fast the picture on the screen is updated. For dynamic pictures, such as TV or games, a high refresh rate will make the picture look smoother and not prone to shadows.
3. Understand product quality control and certification
When it comes to high quality, we usually think of a series of rigorous certifications and certificates.
For LED displays, having these certifications not only represents the excellent quality of the product but also means that it meets strict international and industry standards. So, what certifications should a high-quality LED display have?
初めに、 international certification is an important basis for assessing whether the product meets the requirements of international standards and regulations. For example, CE (European Community) certification is a basic access requirement for the European market, which ensures that products meet European health, safety, and environmental protection standards.
RoHS (Restriction of Hazardous Substances) certification requires the content of harmful substances in products to meet EU restriction standards, which helps to protect the environment and human health. In addition, FCC (U.S. Federal Communications Commission) certification is aimed at electromagnetic compatibility to ensure that the product does not interfere with other devices when used.
第二に、 industry certification is the key to assessing whether the product meets the requirements of a specific industry. For example, China’s 3C certification is a mandatory certification system for electronic information products, which includes requirements for product safety, electromagnetic compatibility, and environmental protection. The 3C-certified product means that it meets the requirements of national standards in these aspects.
In addition to the certification itself, we also need to pay attention to the authority of the certification body. Authoritative certification bodies will conduct comprehensive and impartial testing and evaluation of products to ensure that products meet relevant standards and requirements.
Therefore, when choosing LED displays, we should choose those products certified by authoritative certification bodies.
加えて, you need to pay attention to the authenticity and validity of the certificate when purchasing. Manufacturers can be required to provide relevant quality certification certificates and verify the authenticity and validity of certificates through official channels. In this way, you can avoid buying fake and inferior products.
ついに、 even if the product passes strict quality control and certification, regular maintenance is the key to maintaining product performance and quality. Therefore, it is also very important to know whether the manufacturer provides perfect after-sales service and technical support. This can ensure that problems encountered in the process of use can be solved and repaired in a timely manner.
4. Field inspection and sample testing
Field inspection and sample testing are two important links in evaluating the quality of LED displays. They can give you a more comprehensive understanding of the actual performance and quality of the product so as to make more informed purchase decisions.
1). Make an on-the-spot investigation
An on-site inspection is an effective way to directly observe the product production process, quality control, and manufacturer strength. During the field trip, you can pay attention to the following aspects:
- Production environment and equipment: observe the cleanliness, advanced equipment, and maintenance of the production workshop. These factors can reflect the manufacturer’s production capacity and quality.
生産工程： Understand the production process of products, including the procurement, processing, assembly, and testing of raw materials. Observe whether there are strict quality control measures in each link.
Quality control system: Understand whether the manufacturer’s quality control system is perfect and whether there are professional quality inspection personnel and equipment. Ask the manufacturer how to carry out quality inspection and control of raw materials, semi-finished products, and finished products.
R&D ability: Understand the manufacturer’s R&D ability, including new product development, technological innovation, and other aspects. This can reflect the manufacturer’s technical strength and innovation ability.
After-sales service: Understand the manufacturer’s after-sales service system and service quality, including after-sales service response time, maintenance ability, etc. This ensures that you can get timely technical support and repair services after purchase.
2). Sample test
Sample testing is an important means to directly evaluate the performance and quality of actual products. When conducting sample testing, you can focus on the following aspects:
表示効果: Observe the display effect of the LED display, including brightness, color reproduction, viewing angle, etc. Ensure that the display screen can present clear and bright images under different light conditions.
安定性： Test the stability of the LED display, including performance changes, temperature control, and other aspects after long-term operation. Ensure that the display can maintain stable performance during long-term use.
