Resolution LCD splicing screen brightness difference

Currently large-screen LCD display area is a popular product , I believe most users of Samsung's latest 7.3mm Ultra Narrow splicing screen is not strange, but it comes to the mosaic screen 7.3mm ultra-slim bezel there 700cd/m2 with 450cd / m2 of the points, most people would likely confused .
The brightness of the LCD screen is determined by the LCD panel , and currently in the country, can not produce LCD splicing screen panel that last year the first domestic production of LCD panel production line ,20x2 oled display BOE 6.5 generation line can only cut 37 inches below the LCD panel for small-size LCD TV and computer monitor. So that no matter which one you choose manufacturers of LCD splicing screen , as long as the other is Samsung 's LCD panel , brightness, contrast and other parameters are hard we can not change . So before you choose , be sure to choose according to their needs different brightness LCD splicing screen .
For now, using Samsung LTI460AA04 (700cd/m2) lcd module with LTI460AA05 (450 cd/m2) LCD panel LCD splicing screen, in the direction of the main application and the two products are not essentially different . However, due to different application environments require different brightness for large screen leaving the two products in specific applications generated on nuances.
Generally, people's eyes for the brightness tolerance is limited , if the light is poor small space, if brightness of 700cd/m2, the human eye is likely to be burned ; However, if the majority in bright outdoor space such as square , street , display brightness if 450 cd/m2, then the image will be blurred for people in terms of . Therefore, I propose that users buy products should be based on their actual application environment , but also in the light somewhat less space is more limited range of places LTI460AA05 applicable , by contrast , the vast space lit LTI460AA04 become preferred .
In addition, Ultra Narrow LCD splicing screen , its optimum operating temperature is 39 degrees Celsius and a relative humidity of 90% in the control area of ​​the largest of its best working condition . The higher the brightness of the LCD splicing wall they emit more heat , if the heat is not in place, causing light display greatly reduced , can also cause serious damage to the LCD video wall , affecting life. In terms of users , should be considered in the choice of products to their actual ability to operate .
