У наш час, LED displays are not only widely used outdoors, but also increasingly applied indoors, with screen areas exceeding 3 квадратных метраў. Таму, in this situation, there are three options to choose from: LCD splicing screen, DLP (digital LCD rear projection), and LED display screen.
So what aspects should we pay attention to when choosing indoor LED display screens?
1、 Encapsulation form. The LED surface forms of indoor LED display screens include single light, sub surface mount, three in one surface mount, and three in one surface mount, and the appearance is also different. The advantages of surface mount packaging are large viewing angle and good consistency of light emission. Easy to automatically weld and process, it is the mainstream product of full-color LED screens, but now the price is relatively high; The single lamp has a relatively small viewing angle, slightly higher brightness, and lower price. Yabiao stickers are actually a type of single lamp. Single lamps and sub surface stickers are relatively cheap and are transitional products.
2、 Шчыльнасць. Due to the high heat generation of indoor full-color LED chips and the high density of control circuits, the dot density of commercially available full-color screens cannot be made very high.
3、 Рэальныя пікселі і віртуальныя пікселі. Like outdoor full-color screens, indoor full-color screens are also divided into two types of pixels: real pixels and virtual pixels.
4、 Tube core. Good chip can ensure the quality of LED
5、 Метад кіравання. The driving method for indoor full-color LED displays is constant current driving, using dynamic scanning methods (галоўным чынам 1/4, 1/8, і г.д.). In the case of the same chip, more circuits and higher brightness are required for 1/4 сканаванне.
Other factors include the brand, manufacturer, пасляпродажным абслугоўванне, and price of the LED display screen.
