LCD brightness is determined by the LCD panel, but at present in China, can not produce LCD splicing panel, last year's first domestic production of LCD panel production line, BOE 6.5 generation line can only cut 37-inch LCD below Panel for small-size LCD TVs and computer monitors. Therefore, no matter which manufacturer you use to produce the LCD splicing screen, as long as the other party uses the Samsung LCD panel, the hard parameters such as the brightness and contrast are all we cannot change. Therefore, before choosing, you must buy different brightness LCD splicing screen according to your own needs.
For the moment, the use of Samsung LTI460AA04 (700cd/m2) LCD panel and LTI460AA05 (450cd/m2) LCD panel LCD splicing screen, the two main products in the direction of the main application is not essential difference. However, due to the different requirements of different application environments on the large screen brightness, the two products have a slight difference in specific applications.
Generally speaking, the human eye's tolerance 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 the light is in a bright outdoor space Such as the square, street, if the brightness of the display at 450cd/m2, then the image will be blurred for people. Therefore, the author suggests that users should choose the LTI460AA05 in light of poor lighting and limited space when purchasing products. However, the LTI460AA04, with its well-lighted space, is preferred.
In addition, the ultra-narrow LCD splicing screen, the appropriate operating temperature is within 39 degrees Celsius, and the relative humidity of 90% controllable area to reach the maximum, is its best working condition. The higher the brightness of the LCD splicing wall, the more heat it dissipates, if the heat is not in place, the display effect will be greatly reduced by the light, and serious will also cause damage to the LCD wall, affecting the service life. As far as the user is concerned, his own practical ability should be taken into account when choosing a product.
