It is not necessary to change the bulb. After the brightness is superimposed, it reaches the true international standard of 100 ANSI lumens), our optical machine With 100% off-axis function, it is more conducive to lifting, put 100 inches, only need 2.5m distance, 10 high temperature coated pure glass lens, transparent Motherboard: All the main control chips are from the United States, Japan, South Korea, Taiwan, and the performance is very stable. This machine uses a PCB mainboard with a 6-layer blind buried via technology, which has good heat dissipation and high stability. We have the real 3D function of DLP-LINK. The processor is a 64-bit 4 core of Taiwan Mstar A53 architecture, which can hard-decode 4K video sources without stuttering, and the image quality is super clear. into a 2*5W subwoofer. The focus motor is Nidec's focus motor, all-electric focus, no freezing, our radiator uses 60W margin of precision heat pipe + fin design, Taiwan-built standard fan, continuous use of highlights, fundamental Unable to feel the temperature. The machine has a built-in Android system. Software code can be written at will to achieve the desired functions. We have hardware design and Android software development capabilities. After more than two hundred days of debugging, the performance is very stable, no jams, no crashes, The operation is very smooth, the desktop UI is simple, and can be used by 3-year-old children and people. 60 years old. It is wireless on the same screen. As long as it's connected to a 5G router, there's virtually no lag.
