The successful development of Qipu Optoelectronic LED outdoor advertising machine makes the high-tech display equipment that can only be used in government agencies and high-end places. Now it can be seen in regular shopping malls and even in general stores. It is really a group of "old time Wang Xietang Qianyan The trend of flying into the homes of ordinary people. 
Qipu Optoelectronics' advertising machine has the following unique advantages compared with its peers:
First, the size of the advertising machine is 2460mm*1360mm*135mm, and the display size is 1920mm*1280mm.
The display body is made up of 3*2 boxes. The size of the unit box is 640*640mm, and the module is 320mm*320mm. The advertising machine can be matched with any of the spacing type products of Qipu Optoelectronics. As long as a sleek and structurally waterproof cover is added to the finished module, the protection level of the product can reach IP65. This realizes that this advertising machine can be compatible with all the modules of the company and realizes the universal design of the product. The module uses a 4.2V power input design, which is more energy efficient and stable than the conventional 5V power supply.
Second, the screen body adopts the design method of the box body and the box body, and each box body is equipped with a tension lock on the upper and lower sides, and the module surface is on the same horizontal surface by the high-precision positioning mechanism, and the flatness is ≤0.2. Mm, so that the module does not see the bright line or black line between the module and the module when it is completely white. The rear line of the screen adopts a hidden wiring method, and the disorder of the usual display screen is too small, too long, and overlapped. The box is made of 5052 series aluminum plate. The alloy has high strength and has certain fatigue strength. Compared with the general cold rolled plate (SPCC), the weight is 1/4 lighter and the structural performance is not affected. It can be easily lifted, assembled with the left hand, and locked with the right hand, making the assembly easy, fast, safe and secure.
Third, the control box is the receiving control center of the whole screen body. The thickened cold-rolled plate SPCC material design is adopted to reduce the center of gravity and make the whole ground firmly on the ground. Wired, 3G, WIFI control technology enables remote, close-range, manual control. You can easily control the display text, pictures or videos on the display screen without leaving the house, or as far away as you can.
Fourth, the base is made of 5mm thick steel plate, which further reduces the center of gravity of the whole screen. Four adjustable foot cups are provided under the base to allow fine adjustment of the product on uneven ground.
Fifth, the screen body is surrounded by high-end fashion aluminum profiles, so that the screen has a unique decoration. The profile is quick to install, the shape is high-end fashion, and it has a finishing touch in the screen. Colors can be changed arbitrarily according to different environmental decoration effects or customer preferences. The weight of the whole screen is about 150KG, and the longest length is only 1280mm. The back box of the private car can easily load all the materials needed for one screen. It can quickly and conveniently install and debug a whole machine advertising machine in 30 minutes.
Qipu Optoelectronics' advertising machine is the best digital display device application for exhibitions, hotels, large shopping malls, shopping centers, schools, banks, 4S shops and other places. 
With the rapid development of society, the informationization process has gradually become regionalized, and a new technology has emerged as the times require - LED outdoor advertising machine. The newly developed LED outdoor advertising machine of Qipu Optoelectronics has the dual guarantee of high reliability and high energy saving, and has the advantages of simple structure and good display performance.
