D256 16*16 pixel display panel Product Overview D25616*16 Pixel display panel is a LED dot matrix display product witch is specially designed for the field of LED-Clothing, it has many advantages as follow: Small size, light weight, arbitrary curved, easy to carry, Low-voltage drive, green energy, high brightness, low power, long life. D256 use our Company’s advance Intelligent LED driver IC, WS2812 as the basic unit. 16 Pixels are placed each line, and there are 16 lines on each panel. The space between each pixel is 1cm. This product is totally able to meet the basic requirement of Chinese character displaying. When used it with a controller additionally, it can also display numbers, English, video and so on. The Main Application areas ● LED-Clothing products ● Stage Lighting，decorating ● Require frequently disassembly.
