A brief analysis of the difference between LCD splicing screen and small spacing LED screen

A. From the aspect of display effect: no matter what type of display device, display effect is the core selection criterion. Because the display effect is determined by the display technology in most cases, in many cases, users only need to have a clear purpose to select the appropriate splicing screen when choosing large screen splicing display. But as far as LCD splicing screen and LED splicing screen are concerned, their display effects are different and suitable for different fields.

B. From the aspect of brightness: as far as LCD splicing screen and LED splicing screen are concerned, users need not worry about the lack of brightness. On the contrary, small spacing LED screens, which are famous for their high brightness, are facing the problem of excessive brightness, which leads users to consider whether the display environment is satisfied when choosing LED spliced screens. The LCD splicing screen manufacturer has developed two kinds of brightness splicing screen, 500 cd/m2 and 700 cd/m2, according to the user's needs, which makes the application range of 55 inch LCD splicing screen far larger than that of LED splicing screen.

C. In terms of resolution, although LED splicing screen has been breaking through in recent years, it still can not compete with LCD splicing screen. At present, the general resolution of LCD splicing screen is 1920*1080p, while some LCD splicing screen can display 4K signal. But the higher resolution of LED display means that the difficulty of stability design presents the increase of geometric cardinality, the decrease of pixel spacing by 50% and the increase of backplane density by 4 times. This is why the small spacing LED has broken through the bottleneck of 1.0, 0.8 and 0.6, but only 3.0/2.5 products are widely used. Of course, it does not mean that the higher the resolution, the more users will cross over. In fact, many users will only use mosaic screens with general resolution. Because the higher the resolution, the more difficult the technology needed to overcome, which will be accompanied by increased equipment costs. This leads to not many users choosing high resolution.

D. Thickness of splicing unit: LCD splicing screen has congenital advantages in thickness, and has been constantly improving the optimization. At present, the small spacing LED splicing screen has achieved ultra-thin design, because of technical reasons, it will not have much room for improvement in thickness in the future.

E. In terms of optical pollution and visual comfort, LCD mainly refers to dazzling light and high frequency blue light, while small spacing LED is too bright and high frequency blue light.

F. Consumables and display life: the beads and backplane used in the LED display screen, the individual difference of the beads and the stability of the backplane determine that the life difference between single splices of this kind of product is significant, and individual units may need to be replaced soon. The life of LCD splicing screen is mainly determined by the LCD screen and backlight system. The overall life of LCD splicing screen can be known to be between 60,000 and 70,000 hours, and after a long period of use, its color, resolution, visual angle and so on will not change.

G. In terms of heat dissipation: Compared with other display devices, one of the advantages of LCD splicing screen is low power consumption. And the LCD splicing unit has an independent heat dissipation system, which ensures that the LCD splicing screen can be used stably for a long time. Although the small spacing LED has the characteristics of low power density, the overall power consumption is still higher. At the same time, the small spacing LED display products with high heat dissipation requirements also mean that the system noise is higher.

In a word, LCD splicing screen and LED display screen have their own advantages in the field of display, and only in the appropriate use environment can they give full play to their unique advantages. But at present, in many monitoring fields, LCD splicing screen is used to form LCD splicing large screen display system, while in open places such as shopping malls, where there is a large flow of people, the use of LED splicing screen to form large screen advertising screen.
