At present, LCD large-screen splicing is a popular product in the display field. It is believed that most users are familiar with Samsung's latest 7.3mm ultra-narrow-edge splicing screen, but the 7.3mm ultra-narrow-edge splicing screen also has 700cd/m2 and 450cd/M2 points, which may be confusing for most people.
The brightness of the LCD screen is determined by the LCD panel. Currently, LCD splicing screen panels cannot be produced in China. Last year, China's first LCD panel production line, the BOE 6.5 line, could only cut LCD displays into 37 inches or less. The panel is suitable for small LCD TVs and computer monitors. In other words, no matter which manufacturer you choose to use the LCD splicing screen, as long as the other party uses Samsung's LCD panel, the hard parameters such as brightness and contrast cannot be changed. Therefore, before choosing, you must choose LCD splicing screens with different brightness according to your needs.
At present, the LCD splicing screen of Samsung LTI460AA04 (700cd/m2) LCD panel and LTI460AA05 (450 cd/m2) LCD panel has no essential difference in the main application direction of the two products. However, due to the different requirements for the brightness of the large screen in different application environments, these two products have subtle differences in specific applications.
Generally speaking, the human eye has a limited tolerance for brightness. If the brightness reaches 700 cd/m2 in a small space with weak light, the human eye may be burnt; but if it is in a bright outdoor space, for example, if the brightness of the display is 450 cd/m2 on a square or street , The image will be blurry for people. Therefore, the author suggests that users should choose LTI460AA05 in places with insufficient light and limited space according to the actual application environment. On the contrary, LTI460AA04 is a good space with plenty of light.
In addition, for ultra-narrow-edge LCD splicing screens, the appropriate working temperature is within 39 degrees Celsius, and the maximum controllable area is 90% relative humidity, which is the best working condition. The higher the brightness of the LCD splicing wall, the more heat it emits. If the heat dissipation is not in place, the light display will be greatly reduced, the LCD wall will be damaged, and the service life will be affected. As far as users are concerned, they should consider their actual operating capabilities when choosing products.
