Usb-c opens a new era of portable projector
Currently,USB Type-C (usb-c for short) has become a popular interface, and the rapid charging of usbpd has also become popular. The input ports of many electronic devices have been converted to USB-C Interfaces, such as wireless charging base, intelligent speaker, massager, portable juicer, game console and UAV.
Due to the progress of science and technology and the maturity of 5g technology, the Internet of things and smart home have become the hottest topics today. Portable projector has been gradually integrated into our life, entertainment, study and work. The new portable projector has built-in intelligent system, WiFi and other wireless network functions, and supports the projection screen through voice control. The new portable projector is not limited to teaching and working meetings, and supports the connection to the Internet for viewing, entertainment and other purposes. It also supports wireless connection to iPhone, iPad, iMac, various Android phones, tablets and other portable terminals to realize wireless push display. The new portable projector has a built-in high-capacity lithium battery with strong endurance, and can continue to work for several hours even in case of power failure.
It integrates high-speed data transmission and up to 100W power transmission USB-C The interface has become the best choice for the power interface of the new portable projector. Projection technology is now divided into DLP and LCOS. Among them, the core technology of DLP is in the hands of Ti, and Texas Instruments (TI) can provide digital micromirror device (DMD) chip products. Its principle is to use the control of micro mirror to switch the light to complete the accurate control of color scale and gray scale. On a small DMD chip, there are nearly a million tiny mirrors thinner than hair. Compared with DLP technology, the specific imaging principle of LCOS (liquid crystal silicon) chip technology is similar to liquid crystal LCD. It also uses microcircuit to control the voltage to reverse the liquid crystal and control the polarized light to switch the light, so as to realize the color scale and gray scale. The two technologies have their own advantages and disadvantages. At present, the overall DLP technology occupies the mainstream position in the market. With the technological innovation, DLP technology has more advantages in image digital processing, seamless image without delay, long service life and so on.
If portable projector is used USB-C Interface, data and power are available through USB-C The interface transmits at the same time. The interface can completely replace the traditional usb-a, mirco-b, HDMI and DC, and the product is more concise and beautiful.
USB-C With the integration of this new interface, the portable projector will become more convenient, powered by usb-cpd fast charging adapter, and the charging speed will be faster. Even the portable projector without built-in battery can project at any time and anywhere for work or entertainment. With the improvement of display technology, portable projectors can really let every family enjoy private cinemas.
