Cement resistance: is the resistance wire wound on the alkali heat-resistant porcelain, coupled with heat resistant, resistant to wet outside fixed protection and corrosion resistance of the materials and the winding resistance into the square porcelain box body, using special incombustible cement packing seal.The outside of cement resistance is mainly made of ceramic materials (generally divided into high alumina porcelain and feldspar porcelain).

The beautiful 360-degree full-screen LED display of the 2012 Spring Festival Gala will let the audience feel the visual impact of the aerial photography and the beautiful scenery and the actors. From the current point of view, LED full-color display has become the mainstream, with the advancement of technology, lightweight, environmental protection, remote intelligent control, high-definition, 3D technology, interface optimization will become the main key words of future technology development.
Focus on new materials to make the display lighter and thinner
The traditional LED display is mainly made of iron. Due to the weight limitation of the iron itself, it brings great difficulty to the construction of some wall-mounted external installations with small load-bearing materials. The market puts ultra-thin and ultra-light on the LED display. The appearance requirements, especially after the rise of the rental market. Another new material, aluminum, is increasingly being used in LED display cabinets. According to the reporter's understanding, the aluminum box body adopts the overall watering molding technology, and the anti-corrosion performance is better than iron, which is being adopted by more and more enterprises. The all-plastic LED display exhibited by Panasonic provides new ideas in terms of materials. However, the industry generally believes that the technology of all plastic materials in terms of load bearing and support points is still not mature. “Based on the limited load-bearing capacity of plastics, there are currently some companies that replace aluminum with some non-load-bearing parts in order to achieve light weight. It is not excluded to develop new lightweight and anti-corrosive high-performance alloy materials to replace current iron, aluminum, plastic, etc. The possibility of traditional materials.†Mr. Wang Wenping, manager of R&D department of Shenzhen Decolor Optoelectronics Co., Ltd. said.
HD will become the new technology appeal point of the whole industry
“HD currently has no standard definition in the LED display industry. It is generally considered that the 1920*1080 standard is HD display. However, it is generally believed that the P4 and P6 displays have reached the HD level in the industry. However, it is related to the display size, according to the following. The formula is calculated, that is, 1080*6 mm = 6.48 m, which means that only a width of 6.48 m can be used to make a high-definition display."
Mr. Peng Dehua, Manager of Application Engineering Department of Shenzhen Lehman Optoelectronics Technology Co., Ltd. said. The market has already seen a real high-definition LED display. For example, the 1000 square meter P30 LED display released by Shenzhen Ruituo Display Technology Co., Ltd. has reached the absolute HD effect of 1920*2480.
