4 teach you how to choose high-quality LCD splicing screen

The government, enterprises and institutions pay special attention to the public image. They often use indoor high-definition LED screens or LCD large-screen video wall splicing screens to meet the needs of raising public image and efficiency.

Whether it is an indoor high-definition LED screen, Meitu as a small-pitch LED screen, LCD large-screen video wall splicing screen is an expensive project, more than ten million, hundreds of thousands or even millions of dollars.

Therefore, for such an important project, it is very important to select a high-quality, high-quality LCD splicing screen with high efficiency.

So how to choose a good quality LCD splicing screen?

1, see the brand

At present, everyone in the LCD industry knows that the most important part of the LCD splicing screen is the LCD panel, and the best LCD panel manufacturers are Samsung, LG, Sharp, AUO, and Chi Mei.

In particular, the Samsung LCD splicing screen is the most widely used 46-inch LCD splicing screen due to its advanced process manufacturing technology, quality control, color rendering and practical application effects. Most of the 55-inch LCD splicing screens are produced by Samsung. In the entire LCD industry, the security industry, business was how the industry as a hurricane dragged nearly 10 years, from Samsung in the introduction of 46-inch 6.7mm LCD splicing screen, LCD splicing screen constantly updated, there are currently 1.7mm fight Slit LCD splicing screen, this very narrow stitching LCD splicing screen has less and less influence on the visual effect. On the basis of 3.5mm and 1.3mm LCD splicing screens, there are now several companies such as Shenzhen Mitovision, Wellcome vision, and Birdie through optical technology, LED lamp bead embedding technology, enabling ultra-narrow edges, extremely narrow edges The LCD splicing screen achieves a seamless visual experience. A company only pays attention to product technology innovation, product quality and after-sales service can win the favor of customers in the market competition, but also because the company wants to win the customer, he will continue to introduce new products, do a good job of product innovation, quality control and after-sales service.

The LG LCD panel produced by LG has the strong technical support. The IPS technology applied to the LCD panel is superior to the Samsung S-PVA panel in terms of color, clarity, contrast, and saturation. The technical advantage of LG-IPS lies in its hard-screen characteristics and its wide viewing angle of up to 178°, which has also won many manufacturers and engineering customers.

Sharp's supply of LCD panel panels is very small, and its size is very small, mainly 60-inch. Other sizes do not see Sharp's panel in the market, and Sharp's LCD panel prices are also very expensive.

AUO and Chi Mei Qun Chuang are Taiwan's panel makers. Their panel technology is mainly derived from the introduction of Japanese panel makers. Samsung is relatively technically the leader in the industry. LG and Sharp are slightly lacking, but their prices are low and their output is also low. Not bad.

Several large LCD panel manufacturers

Samsung: South Korea

LG: South Korea

Sharp: Japan

AUO: Taiwan

Chi Mei Qun Chuang: Taiwan

2, see patchwork

LCD screen splicing screen is the most important and most difficult to break through the technical indicators lies in the size of its patchwork, LCD seam patch size size from 6.7mm patch to 5.5mm patch to 4.9mm patch to 3.5mm patch to the current pole Narrow seams 1.7mm seams have been developed and technologically advanced over the years. The liquid crystal splicing screen is filled with liquid crystal molecules between two glass bases due to the properties of the liquid crystal itself, and then the light source is added behind the middle polarizer, the reflector or both sides to achieve the purpose of display. Because of this property, the liquid crystal splicing screen must have a frame to fix the glass substrate, polarizer, reflector, etc., and must have a certain degree of strength so that the display components inside the liquid crystal panel will not be clearly damaged or deformed and overflowed. The engineering technicians and installers who have contacted the LCD splicing screen all know that because of the large display area of ​​the LCD splicing panel, the relative bearing strength of the glass is relatively weak, so it is easy to be damaged due to excessive handling or installation force or uneven force. , Leakage, Huaping, white screen and other issues, so be careful in the installation process, not due to overs and forced excessive liquid crystal panel glass caused by cracking or leakage.

When the frame of the LCD splicing screen becomes narrower and narrower due to the higher and higher visual requirements of the market, the outer frame of the fixed liquid crystal glass substrate, the polarizer, the reflective plate and the like must also be thinner and thinner and surround the liquid crystal display. The border around the screen component is also getting lighter and shallower. As a result, the liquid crystal display panel and the display panel of the liquid crystal panel are more prone to overflow, leakage, or breakage of the liquid crystal glass due to mistakes in transportation and installation. Due to the high price of the liquid crystal splicing panel, it often results in a large loss, so in the pursuit of high visual enjoyment, we must also pay attention to this issue.

In the practical application of LCD splicing screens, people often feel sorry for the LCD splicing screens because of the ultra-high resolution, extreme clarity, saturation, contrast, brightness and wide viewing angle of the LCD splicing screen. The division of a thin black line leads to incompleteness of the picture and characters. Even if the technology is used to hide the black border display area, it is imperfect in the perfect display effect. It is precisely because of this constant demand for a more perfect and better visual experience. The market has also introduced Mito 0 seam LCD splicing screens, LED lamp bead mosaic seamless LCD splicing screen, optical seamless LCD splicing screen, etc. New era products. The biggest highlight of this product is through the optical principle or LED display technology to hide the seam of the LCD splicing screen from the visual invisible, although its physical patchwork still exists, but in the visual experience effect is much better than the traditional The effects of the seamed LCD splicing screen.

3, see the brightness

LCD splicing screen brightness is usually measured with cd (candela), nit (nit), lumens, the brightness of the LCD splicing screen will directly affect the clarity of the LCD splicing screen, permeability experience, if you put a 700cd and A 450cd LCD splicing panel, you can easily identify the difference between them, 700cd highlight splicing screen effect than the 450cd low-light splicing screen in the visual experience to be clear, clear, transparent sense is much stronger . However, unfortunately, this kind of indicator that affects the visual effect of the LCD splicing screen except the patchwork often lacks the corresponding instrument measurement. Since the instrument for measuring the brightness of the LCD splicing screen is relatively expensive, it is usually very rare. In a large number of cases of LCD splicing screens in these years, many friends of Party A and the engineering company were secretly using the illegal means of filling the screen with a bright screen to make a huge profit because of the highlight LCD splicing screen and low-brightness LCD splicing screen. In the market price difference of nearly 2 times, so this profit has greatly stimulated the profit-making psychology of some illegal manufacturers. Shenzhen Mito has solemnly promised its customers that it will never use the low-light LCD splicing screen as a dastardly means of highlighting the LCD splicing screen to illegally capture the interests of its clients.

4, see work

Good LCD splicing screen products must be attention to detail, LCD splicing screen machine in the production process, excellent manufacturers must pay attention to every detail, through the control of each component to ensure the quality of LCD splicing screen, such as LCD Whether the alignment of the panel is neat and orderly during the installation, whether the heat tape is effective to fix the screen line, the backlight line, and whether the cable tie is tightly fastened or not, the LCD splicing screen driver board and the power board are selected by the industry's optimization scheme. , LCD splicing screen key board, key line, screen line, backlight line, control line, remote control quality is reliable, whether the quality of liquid crystal splicing screen back cover sheet metal quality, paint quality is high quality, LCD splicing screen machine in the assembly After the completion of a rigorous process and length of aging tests. In addition, whether the important small parts of the LCD splicing screen and the cooling fan have undergone rigorous testing and aging tests. In the installation application project of LCD splicing screen, whether the fixed bracket of the LCD splicing screen is firm and reliable, and whether the hook behind the splicing screen of the liquid crystal stencil is rationally designed to facilitate adjustment and installation and fixation.

In summary, we have a basic understanding of how to choose a high-quality LCD splicing screen. I believe that the LCD industry is not very understanding of the friends, through this article, will certainly be able to choose a high-quality LCD splicing screen products.
