It was actively promoted by Qingdao Merchants Bureau. On the morning of April 8, the sapphire wafer processing project with a total investment of 2.5 billion yuan was held in Qingdao High-tech Zone. This is the first enterprise to start production after the completion of Qingdao High-tech Zone.
This project combines the advanced sapphire wafer processing technology of Silicon Valley in the United States with China's manufacturing cost advantage to form a competitive advantage of excellent cost performance. The long-term goal is to build a LED industry chain with sapphire wafer processing as the entry point. The initial investment of the project is 140 million yuan. After the completion of the project, it will produce 150,000 pieces of sapphire wafers per month, which will fill the gap in the domestic market, replace imports, and gradually expand production capacity.
Substrate wafers are the key basic materials for the semiconductor lighting industry. Among them, sapphire substrate wafers are the most widely used substrate wafers for blue and white LEDs due to their mature technology, good quality and excellent cost performance. They account for global blue and white light. 90% of the amount of LED chips.
After the project's entire industrial chain matures, the project will generate 10 billion yuan in sales revenue and tax revenue of more than 1.5 billion yuan, making Qingdao one of the national semiconductor wafer processing centers and the national semiconductor lighting industrialization base.
We are professional manufacturor more than 10 years providing high brightness, waterproof, dustyproof Outdoor Full color Led Display , which is widely is used in the outdoor environment such as outdoor advertisement, Stadium, Airport, Traffic system, Hopspital, Hotel, Market, etc. The application environment of Outdoor LED Display is normally much worse than the Indoor LED Display. The material & quality standard is also higher than the Indoor Led Display . We provide all series of Outdoor Fixed LED Display models: P3.91mm, P4mm, P4.81mm, P5mm, P6mm, P8mm, P10mm, P15mm, P16mm, P20mm. Since more and more customers prefer higher resolution to improve the video quality, outdoor HD series of P3.91mm, P4mm, P4.81mm, P5mm, P6mm become popular models. In any case, the use of digital video outdoor LED screens from JOYLED LED Screens signifies a brand new stage of development in the area of outdoor advertising. A number of articles have already discussed the strengths of presenting information on LED (Light Emitting Diode) monitors versus the static outdoor stands. The size of the Outdoor Led Screen displays and LED signs are very important to know to determine the resolution per square meter we have to set for the screen. This is to avoid low quality video with very little detail or a very high quality video that is not necessary (in some cases it depends on the customer´s project type). The variable that decides the LED screen resolution per square meter is called the pixel pitch, which tells us the distance between the LED´s in millimeters. The shorter the distance of the LED´s, the higher the screen resolution per square meter, and a greater distance, the resolution will be less. Our full color outdoor LED screens can be divided into two types of groups, which are: Integrated 3in1 SMD LED chips based outdoor LED screens & Dip LED Chips (Oval LED Chips) based outdoor LED screens
