 With the progress of social technology, outdoor advertising is rapidly transforming from traditional static billboards to dynamic digitization. The information transmitted by outdoor advertising machine will not be affected by the weather and can bring good visual and auditory enjoyment. It can be widely used in outdoor advertising, outdoor public information release, outdoor media communication, touch interactive query and other fields all day, greatly improving the sense of picture hierarchy and better displaying details. With the gradual expansion of the use scene of outdoor advertising machine from semi outdoor to all outdoor, its challenges are more diversified.  
 
The brightness standard of outdoor advertising machine industry is that it needs to reach 1500cd / m2 (hereinafter referred to as CD) in the open sky environment to be called outdoor display. Recently, a German professional digital signage consulting organization conducted a group of evaluations on outdoor displays. Through the contrast effect of a group of displays from 450 CD to 3000 CD, it can be intuitively felt that the display effect of only 1500 CD brightness under daylight conditions is not satisfactory. This means that the display brightness of only 1500 CD will cause the attenuation and loss of visual information transmission, which can not attract attention. However, the brightness of Samsung OHD series outdoor display can be as high as 3000cd, which is twice the industry standard. Even in the face of noon strong light, it can ensure a clear and bright display and make the image "backlight" shine.  
 
As a screen display technology, anti glare has been widely used in daily life such as mobile phone, flat panel and display. However, for outdoor advertising machines, if they do not want to become a "public dressing mirror", they need higher anti glare indicators. Especially in the information display scene used in the transportation industry, if the display is unclear or strong light refraction, it will bring great hidden dangers to the road safety. Through its unique technology, Samsung outdoor advertising machine can effectively enhance the picture visibility and reduce the specular reflection generated by the screen by enhancing the picture contrast and Samsung's exclusive patented reflection elimination film. At the same time, Samsung outdoor advertising machine is not only "anti glare", but also "anti polarization". Through the application of circular polarizing technology, the problem of "display blind area" caused by the traditional LCD when people wear polarizing sunglasses is solved, which provides a more comprehensive guarantee for road driving safety.  
 
Outdoor advertising machine is an important terminal in the information construction of smart city and an important element in building city business card. The development of outdoor advertising machines will provide a strong boost for the construction of smart cities in China.
