LCD splicing screen is currently a popular product in the display field. I believe most users are familiar with Samsung's latest 7.3mm ultra-narrow LCD splicing screen, but when it comes to 7.3mm ultra-narrow LCD splicing screen, there are 700cd / m2 and 450cd / m2 In terms of points, most people may be confused.
The brightness of the LCD splicing screen is determined by the LCD panel. At present, it is not possible to produce LCD splicing panel in China. The first LCD panel production line in China last year, the BOE 6.5 generation line can only cut liquid crystals under 37 inches. Panel for small LCD TVs and computer monitors. That is to say, no matter which manufacturer's LCD splicing screen you choose, as long as the other party uses Samsung's LCD panel, we can't change the hard parameters such as brightness and contrast. So before choosing, be sure to buy LCD splicing screens with different brightness according to your needs.
700cd / m2 LCD splicing screen VS 450 cd / m2 LCD splicing screen
For now, the LCD splicing screens using Samsung LTI460AA04 (700cd / m2) LCD panel and LTI460AA05 (450 cd / m2) LCD panel have no essential difference in the main application directions. However, due to the different requirements for the brightness of the large screen in different application environments, the two products have subtle differences in specific applications.
Generally speaking, the tolerance of human eyes for brightness is limited. If the brightness is 700cd / m2 in a small space with poor light, the human eye may be burned; however, if it is in a large outdoor space with bright light For example, if the brightness of the display screen is 450 cd / m2, such as a square or a street, the image will be blurred for people. Therefore, the author suggests that users should choose the product according to their actual application environment, LTI460AA05 is more suitable in places with poor lighting and limited space range, and on the contrary, LTI460AA04, a wide space with sufficient light, is preferred.
In addition, for the ultra-narrow LCD splicing screen, the suitable working temperature is within 39 degrees Celsius, and the maximum controllable area is 90% relative humidity, which is the best working state. The higher the brightness of the LCD splicing wall, the more heat it emits. If the heat dissipation is not in place, the display effect will be greatly reduced if the light is dissipated, and the LCD wall will be seriously damaged and affect the service life. As far as users are concerned, they should consider their actual operational capabilities when selecting products.
