For many people, the micro projector is still a new technology product. If you want to buy a mini projector, you need to understand the parameters, indicators, performance, function, brand, etc. of the mini projector before you can buy a satisfactory mini projector.
First, the characteristics of the micro projector
The so-called mini-projector is smaller than the traditional projector, and the remarkable feature is that the mini-projector that can be put in the pocket becomes a pocket-type mini-projector.
2. Types of micro projectors
Micro projectors currently have built-in Android system micro projectors, multimedia micro projectors, wireless connection micro projectors, dedicated micro projectors, and writing touch micro projectors.
Third, the brightness of the micro projector
The brightness of the micro projector is related to the size, bulb, optical machine, heat dissipation, etc. The small size of the micro projector has relatively low brightness, and the larger size will be higher; the brightness of the bulb will be higher when using Osram, and the use of domestic Ordinary bulbs will be low; using TI’s DLP chip will have high brightness, using LCD panels will be low; using 3-color LED lights will be high brightness, using a single color, the brightness of the software color will be low, users pay attention to buying brightness Practical micro-projectors, there are indeed some on the market that use ordinary LEDs, etc., use monochromatic light sources, and use ordinary liquid crystal panels to make the so-called micro-projector brightness that is not practical.
Fourth, the clarity of the micro projector
The definition of the micro projector is mainly composed of three parts: one is the DLP chip; the other is the system chip; the third is the optical system. At present, the resolutions of micro projectors on the market are 850*480; 1280*800; 1920*1080; 4096*2160. The small size of the mini projector is mostly 850*480, and the basic one used for home film and television is 1280*800; at higher resolutions, the resolution of 1980*1080 is high, and the higher is 4096*2160 ultra-clear 4K mini projector.
Five, the resolution of the micro projector
The resolution of the micro projector reflects the layering and fineness of the picture quality of the micro projector, and the usual range is 1:2000 to 1:150000.
Six, the function of the micro projector
At present, the micro-projector is not used as a large output screen in the traditional sense, but a multifunctional household appliance. In addition to projecting a large 300-inch screen, it can also be used as a TV, with more channels and resources than usual TVs; it can be used as a reading machine for early childhood education; it can be used as a drawing board for children’s graffiti painting; karaoke can be sung; The virtual fitness game can be used to build a home 5.1 music center; it can be used as a home monitoring device.
Seven, the quality of the mini projector
The quality of the micro projector is determined by the manufacturer’s design, craftsmanship, assembly, quality control, quality inspection, aging, environment, and the selection of key raw materials. Take Meigao as an example. In addition to the company’s own craftsmanship in design, process, assembly, quality control, quality inspection, aging, and environment, it also selects the best in the selection of raw materials. For example, the chip uses TI’s new DLP product, optical machine Choose Taiwan Yangming Optoelectronics; the light bulb chooses German Osram, which can guarantee the life of the product up to 30,000 hours.
