The maximum brightness under certain environmental illumination, LED display brightness for each color in the highest gray level, the highest brightness. In a nutshell is the use of software to set the brightness of the display using a light gun in the normal direction when measured as 255 white. For the outdoor LED display according to the environment used to maximum brightness have different requirements, because in case of strong ambient light Tianjin led display, LED display brightness requires higher, to let people see on the screen what is displayed. Under normal circumstances, the display look northward for maximum brightness requirements low, long reach 4000CD / m2 will be able to meet the requirements, and ride south of display brightness of the entire screen is required to achieve 7000CD / m2, east and west and south of the requirements are the same led display production, because most of the time there will be a direct exposure to sunlight will the LED display. Theoretically require more than 5500CD square meter brightness brightness is sufficient. The method is simple: look at the power behind the number of housing, multiplied by the maximum power of each power supply, according to the size of the box you can calculate the maximum power meters, power general use, there are two, 200W and 300W power supply. Usually refers to the use of power is to play advertising video, text, pictures power led display manufacturers, the use of power and broadcast content directly related to led display, it is difficult to have a precise value, but according to Our experience, usually 1/3 of the maximum power consumption. Lower power consumption on behalf of lower cost and smaller heat which depends on the current size, a direct impact on the life and stability of the display.
