Any national government, enterprises and institutions pay special attention to the public image, they often due to the need to improve public image and efficiency, thus using indoor high-definition LED screen or LCD large screen TV walls or videowall. Whether it is indoor HD LED screen, MitoVision small pitch LED screen, LCD large screen TV wall is a pricey project, often more than 100,000, hundreds of thousands or even millions of dollars.
Therefore, such an important project, efficient choice of good quality, high quality LCD videowall is very important. So how to choose a high-quality LCD videowall?
1. Focus on the brand
Everyone in the LCD industry knows that the most important component of the LCD videowall is the LCD panel, and the best LCD panel manufacturers belong to Samsung, LG, Sharp, AUO, Chi Mei Qun Chuang.
Samsung LCD videowall due to its advanced technology manufacturing technology, quality control, color rendering and practical application effect, the market's most widely used 46-inch LCD videowall, 55-inch LCD videowall are the vast majority of Samsung's products, in the entire LCD industry, security industry, commercial display industry how the wind in full swing for nearly 10 years, from Samsung in the zero years since the launch of the 46-inch 6.7mm LCD videowall LCD videowall, LCD videowall constantly updated, there is already 1.7mm videowall, this very narrow videowall on the visual impact of the LCD videowall is getting smaller and smaller.
In 3.5mm, 1.3mm LCD videowall based on, now there have been several companies such as Shenzhen Wellcome Vision, Shenzhen CY Digital Signage Smart Display Technology through optical technology, LED lamp beads embedded technology, so that ultra-narrow edge, very narrow edge of the LCD videowall to achieve a seamless visual experience. A company only focus on good product technology innovation, product quality and after-sales service to win the favor of customers in the market competition, but also because the company wants to win customers, he will continue to push the new, good product technology innovation, quality control and after-sales service.
LG company production of LCD panels due to LG's strong technical support, its application in the LCD splicing panel IPS technology compared to Samsung S-PVA panel color good, clarity, contrast, saturation and other advantages. LG-IPS technical advantage is its hard screen characteristics and up to 178°ultra-wide viewing angle, so also won a lot of manufacturers and engineering customers.
Sharp in the LCD videowall panel this piece of supply is very little, and the size is very little, mainly 60 inches, other sizes do not see the circulation of Sharp's panels in the market, and Sharp's LCD panel prices are also very expensive.
AUO and CMO is a panel manufacturer in Taiwan, its panel technology is mainly introduced by Japanese panel manufacturers to develop, in technology relative to the industry leader Samsung, LG, Sharp is slightly inadequate, but the price is lower, the output is also good.
Several large LCD videowall panel manufacturers origin:
Samsung: South Korea
LG: South Korea
Sharp: Japan
AUO: Taiwan
Chi Mei Qun Chuang: Taiwan
2. Focus on the spacing
LCD videowall is the most important and most difficult to break through the technical indicators is the size of its spacing, LCD videowall size from 6.7mm spacing to 5.5mm spacing, 4.9mm spacing to 3.5mm spacing, and then to the current very narrow spacing 1.7mm spacing. After several years of development and technological breakthroughs, LCD videowall due to the properties of the liquid crystal itself, between the two-glass basic filling liquid crystal molecules, and then in the middle of the polarizer, behind the reflector or both sides to add light to achieve the purpose of display. Because of this property, make the LCD videowall must have a frame to the glass substrate, polarizer, reflector, etc. fixed up, and must have a certain strength to make the LCD panel inside the display components will not be clear breakage or deformation spill.
Contact with the LCD videowall engineers and technicians, installers know that the LCD videowall panel due to the large display area, the glass is basically relatively weak pressure strength, so it is easy due to handling, installation of excessive force or uneven force breakage, liquid leakage, flower screen, white screen and other problems, so in the installation process must be careful, do not due to carelessness and excessive force caused by the LCD panel glass rupture or liquid leakage.
When the LCD videowall bezel due to the increasing visual requirements of the market needs to become narrower and narrower, fixed LCD glass substrate, polarizer, reflector and other components of the outer bezel must also become thinner and thinner, surrounding the LCD display components around the bezel is also becoming shallower and shallower. This leads to the LCD screen, LCD panel display components more easily due to transportation, installation errors and lead to liquid crystal glass overflow, leakage or breakage. And due to the high price of the LCD splicing panel, often resulting in larger losses, so in the pursuit of ultra-high visual enjoyment at the same time also pay attention to this aspect of the problem.
In the actual application of the LCD videowall, people because of the LCD videowall ultra-high resolution, extreme clarity, saturation, contrast, brightness, wide viewing angle of the visual experience and cheer, often also regret the LCD videowall that a thin black line segmentation, and lead to the picture, the characters have a little incomplete, even though technical means, the black edge of the non-display area image hidden, but also ultimately perfect The imperfection of the display effect. It is due to this constant pursuit of a more perfect and better visual experience of the demand, the market and launched a new era of products such as MitoVision 0 splicing LCD videowall, LED lamp bead inlay seamless LCD videowall, optical seamless LCD videowall. The biggest highlight of this product is through the optical principle or LED display technology will be invisible from the visual LCD videowall, although its physical splicing still exists, but in the visual experience effect is much better than the effect of the traditional seam LCD videowall.
3. Focus on the brightness
LCD videowall brightness is usually used cd (candela), nit (nits), lumens to measure, LCD videowall brightness will directly affect the LCD videowall sense of clarity, permeability feeling, if at the same time put out a 700cd and a 450cd LCD splicing panel, it is easy to identify the difference between them, 700cd high bright videowall effect than 450cd low bright videowall effect in the visual experience to clear, bright, permeable sense of much stronger.
But unfortunately, this in addition to the stitching outside the main impact on the visual effect of the LCD videowall indicators but often lack of corresponding instruments to measure, due to test the brightness of the LCD videowall instruments are more expensive, so usually very rare. In these years, a large number of cases of LCD videowall, there are a lot of A and engineering friends were secretly using low bright screen filled with high bright screen illegal means to earn a huge profit, because the high bright LCD videowall and low bright LCD videowall in the market price difference of nearly 2 times, so such profits greatly stimulate the profit-making mentality of some unscrupulous manufacturers.
Shenzhen CY Digital Signage to customers solemnly promise never, never use low bright LCD videowall pretending to be high bright LCD videowall such despicable means to illegally profit from customers.
4. Focus on the workmanship
Good LCD videowall products must be focused on details, LCD videowall machine in the production process, excellent manufacturers must be focused on every detail, through the control of each component to ensure the quality of the LCD videowall.
For example, the LCD panel in the installation of the alignment is neat and orderly, whether the thermal tape is effective in fixing the screen line, backlight, whether the tie is tied to the need to tighten the place, LCD videowall driver board, power supply board is to choose the industry's most optimal program configuration, LCD videowall keypad, key line, screen line, backlight, control line, remote control quality is reliable, LCD videowall machine back cover sheet metal quality is high quality, whether the quality of baking paint, LCD videowall. Baking paint quality is high quality, LCD videowall machine in the assembly is completed after a strict process and the length of the aging test.
In addition, the LCD videowall important small parts, whether the cooling fan after strict testing and aging test. In the LCD videowall installation application engineering, LCD videowall fixed bracket is solid and reliable, LCD videowall whole machine behind the hook is after reasonable design, easy to adjust and install fixed.
In summary, we have a basic understanding of how to choose a high-quality LCD videowall, I believe that the LCD industry is not very well-informed friends, through this article, will be able to choose a high-quality satisfactory LCD videowall products. We would love to brainstorm with you on building your next experience! Looking to buy or learn more about our videowalls Contact us.
