• The 0.2-inch DMD optical machine of Texas Instruments, which is actually used by the United States Ti DLP, uses the German Osram LED light source. After the brightness is overlapped, it reaches the real international standard of 120ANSI lumens. Stereo box appearance, creating better sound Hi-Fi 3W. Drop freely between 0.5-5M distance, and the maximum drop can reach 100 inches
• All the main control chips are from the United States, Japan, South Korea, and Taiwan, and the performance is very stable. This machine uses a 6-layer blind-buried-hole technology PCB motherboard, built-in brand fan, excellent heat dissipation effect, continuous work without high temperature, and extremely stable high
• The CPU used is a 64-bit 4-core RK A7 architecture, and the picture quality is super clear and smooth without lag
• All-round clear picture, support 4K viewing. Unlike TVs, projectors use diffuse reflection instead of direct light, which reduces light damage to the eyes. More protection for children, more suitable for the elderly to watch
• This machine has a delicate appearance and a built-in lithium battery. It can watch movies for 1-1.5 hours without charging. It can be used freely for family leisure, education, business office, and small conferences
