Smart projector purchase instructions Optical clarity is not enough

In recent years, smart micro-investment products have become more and more popular in the market, and the excellent price/performance ratio has made it an inevitable choice for entry-level projection enthusiasts. When people choose intelligent micro-projection, the most important reference for comparison is brightness and resolution. Just like buying a car, you must look at the engine. Luminance resolution does not represent all of the projection product's performance. It also requires many considerations when purchasing micro-projections. So in addition to the brightness resolution, what does a good smart micro projector need to have "self-cultivation"?

First look at the brightness of the resolution, these two points have been criticized by consumers, brightness and traditional projectors are still not a small gap, generally between 200-500ANSI lumens, only a very small number of micro-speculative models can break through 500 ANSI lumens, resolution is also difficult to achieve today's TV LCD screen easily 2K, 4K standards, generally only reach 720P. Fortunately, smart micro-investors are on the path of rapid development. Texas Instruments has released its 1080p Full HD chipset last year. This chip can enable intelligent micro-projection to achieve brighter, more efficient full-HD imaging. It can be expected that this year will be a year for the micro investment industry to fully enter the 1080P market, and with high-resolution and high-brightness comes inevitable price increase, but beyond the expected price will make consumers pay for everything? Need to wait for market inspection.


In fact, in addition to the brightness resolution, the micro projector has a lot of places that deserve attention, such as: color gamut, lens material, contrast, fixed zoom function, etc. These are all factors that directly affect the quality of the projected picture. In order to allow everyone to choose the right projector for their products, this article will give you a brief introduction to the few technologies and parameters that are rarely mentioned in the projector.

The gamut determines the vividness of the color

Not only for the projector, the color gamut is a very important parameter for all display devices, and the wider the color gamut, the more the display device can display a true color plot close to the natural world. Anyone who has experienced the use of a projector knows that because the projector can project a large screen size, the details of the screen can be reflected clearly and clearly. If the same color gamut is displayed on the LCD screen with little color distortion, it is reflected on the projector. This is particularly noticeable, which puts forward higher color technology requirements for micro-investment.


At present, the color gamut of ordinary LCD TVs, monitors, traditional TVs, and bulb projectors is generally 60-90% NTSC, and the RGB (timing) LED projector color gamut is generally 80--130% NTSC.色 The color gamut of several miniature projectors can reach the upper limit of the color gamut of LED projectors. Recently, cool music as the latest launch of the "color master" based on the two smart micro-cast cool music as S1 + / S2+ to reach 128% NTSC.

Lens material directly affects imaging quality

Many people are very concerned about the performance of light engines and display chips when selecting micro-projections, and ignore the crucial lens of the projector. For the importance of the lens, I believe photography enthusiasts have a deeper understanding. Lens material is mainly divided into three kinds: resin lens, resin glass hybrid lens, glass lens.


The market mainly circulates resin lenses and resin-glass hybrid lenses. Projection manufacturers usually carry out various kinds of packaging and publicity for such lenses, but no matter how they are packaged, they cannot avoid a congenital defect of the resin material lens: poor heat resistance, as long as the projection Opto-mechanical work will cause the body to heat so that the resin lens "heat expansion and contraction," causing the projector to blur the thermal defocus picture. The glass lens will not cause this problem, but due to the cost of more manufacturers choose the "resin, resin glass mixed lens."

Fixed focus and zoom control screen size

Compared with other display devices, the controllability of intelligent micro-projection on the screen is obviously undefeated, ranging from a few inches to several hundred inches. We can all freely change the size of the screen, but many people will have to change the screen size. The question is: why do you have to move the camera body when you change the screen size, and you can't do it by focusing like a traditional projector! What if you want to cast a bigger or smaller effect within a limited distance? ?



These are the actual problems, and only the zoom lens can solve, and most of the micro-projection products in the market are fixed-focus lenses, while the remaining models equipped with a zoom lens, the zoom ratio can only reach 1.1 Times, 1.1 times is not enough for consumers, consumers need 1.2X, 1.3X or even 1.5X or higher zoom ratio, need a better user experience, so that the use of smart micro-projection, installation has become Very convenient, flexible and simple;

Contrast determines picture detail

Contrast refers to the ratio between the brightest white and the darkest illuminance in an image. Its effect on visual effects is very critical and is directly related to the presentation of the details of the image. Generally speaking, the greater the contrast, the clearer the image. Eye-catching, the more bright and colorful the color; and a small contrast, it will make the entire screen gray. High contrast is very helpful for image clarity, detail performance, and grayscale performance.

According to relevant evaluation experience, if the original contrast ratio of the projector can reach 200:1 (actual non-virtual standard), it can achieve a better grayscale effect and can initially meet the needs of households. Of course, if you want to pursue the ultimate picture experience, of course, try to choose the higher.


In addition to the above factors, smart micro projectors are smart because they integrate the functions of smart TVs, and whether content is rich is also an important reason for selecting smart micro projectors. For many micro shots that are not rich enough, you can try to install them. Third-party app market sofa housekeeper to download more interesting useful app.


to sum up

I believe that through the detailed introduction and analysis of the brightness, resolution, contrast, lens material, fixed zoom function, etc. of the smart pico projector, we all have a certain understanding and understanding of micro-projection products, and hope that everyone will choose micro products in the future. When investing in a product, you should not forget to compare other important parameters when comparing the brightness resolutions, and buy products that are truly suitable for you.
