Clarify the large-screen display effect and budget
The current large{{0}}screen display systems mainly include LCD splicing screens and small-pitch LEDs. The obvious difference between the two is the price and the seam. The LCD splicing screen has 0.88-3.5mm seams, while the small pitch does not. As for the price, the small pitch is calculated in square, and the price of a single square small pitch can range from thousands to tens of thousands, which is relatively higher than the cost of splicing screens. Therefore, users need to consider the display effect and budget when considering the purchase of large-screen splicing.
Screen size and renderings
When users purchase LCD splicing screens, they need to clear the size of the construction site, and then give the size and size of the site to the splicing screen manufacturer, and ask the manufacturer to provide installation effect pictures of 46-inch, 55-inch, and 65-inch LCD splicing screens.
Ultra-narrow splicing screen panel quality
The quality of the ultra-narrow splicing screen connection panel directly affects the working time of the product. However, at present, except for the A plus panel, the LCD splicing screen manufacturers will basically leave the factory with A specification, that is, 80 percent color point rate. Color separation point and dead point of LCD splicing screen panel. The color point refers to the pixel that still emits light when the screen displays black, and the dead point refers to the pixel that does not display color. Since their existence will affect the display effect of the picture, the fewer dead pixels, the better. Consumers are difficult to detect with the naked eye, but users can use the Nokia Monitor Test software to test. Of course, you can also request factory testing.
Generally speaking, in addition to the panel itself, the current purchase of splicing screen projects also includes the purchase of splicing cards and splicing brackets. We will not say more here. We will introduce the two to customers in a single article. The purchase standard.
