In the actual purchase, users can follow the "human-readable brightness level, the better" principle, the so-called brightness level, meaning the human eye can distinguish the image from the black to the white brightness level, led, The brightness level is recognized more, led display control software, the display will show the larger color space, showing rich colors potential for greater natural. About dot pitch selection, full color led display, pay attention to balance the effect of technology 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 consumption, supply is generally used in two, 200W and 300W power supply. Usually refers to the use of power is to play advertising video, text, pictures power, because the use of power and broadcast content directly related to the difference between lcd and led, it is difficult to have an exact value, but according to my Division of 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. the difference between lcd and led, high-Jin Liang photovoltaic (online consultation), led by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd.
