With the rapid development of wearable products and mobile products in the market, a class of products featuring compact appearance, exquisite design, and portable intelligence has quickly become the darling of the market. Smart micro investment products are one of them. . However, for many projection whites, how to choose a relatively high-quality smart micro-investment is still a difficult thing, especially in the case of a variety of brands and models, want to find a and its own The products that meet the demand need to be considered from multiple perspectives.
Many buyers choose the brightness of intelligent micro-projection as the only standard to measure the quality of products, which is actually a more general approach. Because the brightness of current smart micro-projectors is generally low, even laser light source-based smart micro-projections have been introduced. Constrained by the small size of the product, while the cooling function is weak, the brightness of smart micro-projection products is actually difficult to perfect in a short time.
The quality of intelligent micro-projection products directly affects the actual viewing effect
Most intelligent micro-projection products have a brightness value of between 300 and 500 lumens. From a naked eye point of view, the difference is not significant. Instead of using brightness as a measure to purchase intelligent micro-projects, it is better to distinguish them from the quality and intelligence of the product. Although the current resolution of intelligent micro-projection products has basically reached WXGA (1280╳800), the actual image quality will be affected by factors such as contrast and color saturation.
What is the effect of contrast on image quality?
Contrast is the measure of the different brightness levels between the lightest and darkest blacks in the light and dark areas of an image. Theoretically, the higher the contrast, the more contrast the brightness of the projected image from black to white is. The more gradation level is also richer, so the detail performance is more flexible; otherwise, the brightness dynamic range of the entire projection image is narrower, and the gray gradient level is less, so the detail expression effect is poor.
Contrast is an important performance parameter of all display devices. For smart micro-projection products, it will also directly affect the picture quality. In terms of color levels, high contrast has no significant effect on the image. Contrast has more influence on the dynamic video display effect. Because the light and shade conversion in the dynamic image is faster, the higher the contrast, the easier the human eye can distinguish the conversion process. The use of intelligent micro-projection products to watch video content is still a lot of time, so in the process of purchasing smart micro-investment, you should also pay attention to the level of product contrast.
However, it is worth noting that there are two different concepts depending on the measurement method: dynamic contrast and original contrast. Dynamic contrast is the ratio of the brightness of the projector output full white screen and full black screen, and the original contrast is measured using the ANSI 16-point standard (note: ANSI standards developed by the American National Standards Association, this standard is also recognized in the industry Standard) is the ratio of the average of the brightness of 8 white areas and the average of the brightness of 8 black areas in the 16-point black and white inter-color patches. From the reference point of view, the original contrast is more authoritative, but many manufacturers in the parameter specification is the dynamic contrast, in order to know the most realistic contrast information, it is best to view some of the product measured information.
Is the color saturation the better?
Although the contrast also affects the picture quality, the color saturation is the key to affect the color performance of the picture. Color saturation is a numerical expression of the purity of a single color, so in theory, the higher the color saturation, the higher the purity of a single color and the more beautiful the color. The color saturation of a projector product refers to the color depth or vividness of the light projected by the projector. This depends on the white light content in the color, the higher the white light content, the lower the color light content, and the lower the color saturation, which is a percentage, between 0 - 100%.
The color saturation of the projector is the ratio of the projector's color range to the numerator, and the NTSC's three primary color ranges are calculated by the denominator. In general, the color saturation of intelligent micro-projection products is not low, and the color purity is high. This is because lower brightness does not affect the color performance of the projected image, and on the other hand, it is a technical enhancement to meet user needs.
But is the color saturation really higher? This is not true from the perspective of practical application experience. Excessively high color saturation brings out bright color accumulation, which is more dazzling to the user, and long-term viewing can easily cause visual fatigue. From a practical point of view, it also depends on the user's individual preferences for color performance.
How to distinguish the ease of use of micro-projection products?
Smart micro investment products have their own smart operating systems. Users can connect to the network to perform autonomous application operations on the smart operating system. Resolving the ease of use of micro-projection products can start with smart operating systems. The operating system of smart micro investment products is generally composed of film and television dramas, interactive games, music, parent-child education, and so on. There are still many entertainment functions. The user needs to determine whether a smart micro investment product has the ease of use. In addition to viewing the software's practicality in the smart operating system, it is necessary to determine whether the operation process is convenient.
For example, if a micro-projection product has a virtual touch function, it depends on whether it is a direct-touch or remote-control touch, and the touch operation is not sensitive and so on. Some smart micro investment products are still trying to connect product functions with smartphone functions, and voice assistant is a relatively cutting-edge attempt.
Whether or not the battery is built-in is also a distinguishing criterion in the ease-of-use considerations. Bringing the battery means that the camera body can get rid of the connection control and achieve true free projection. At present, only some intelligent micro-injection batteries have been built, which is a bonus item compared to other micro-projection products.
Jingdong's Favorable Rate and Practicality
Now that online shopping is more popular, many people who purchase smart micro-investors are also preferred to use online shopping. However, although online shopping is good, there are no lack of fraudsters. At this time, the evaluation rate and practicality of the e-commerce platform are more important. In the process of reviewing user reviews, do not be brainwashed by previous reviews. It is best to look at the truth of the picture and avoid being run by the navy.
Sometimes when the consumer chooses a product, the merchant often lied that this model was out of stock and instead recommended other products of the same type. When recommending products, merchants are more willing to recommend hot products and newer products so that they can make more money. However, compared with new products, old products, after the full competition of old products, the price drops, the profit rate decreases; while the new products are priced higher, this should be regarded as a trap in online shopping, need to pay attention to the purchaser.
At present, the number of domestic smart micro investment product brands is also increasing, and the corresponding increase in micro investment product shipments, especially the rise of domestic smart micro investment brands, has brought more vitality to the market. At the same time, the overall performance of the product has also been improved, although the brightness can not yet reach the level of professional home projectors, but the entertainment function of the product is still growing.

Interpretation of the concept of contrast
Contrast is an important performance parameter of all display devices. For smart micro-projection products, it will also directly affect the picture quality. In terms of color levels, high contrast has no significant effect on the image. Contrast has more influence on the dynamic video display effect.

It can be seen from the comparison chart that the level of contrast has an effect on the image layering and color performance
The higher the original contrast, the more gray levels are displayed in the projection screen
However, it is worth noting that there are two different concepts depending on the measurement method: dynamic contrast and original contrast. Dynamic contrast is the ratio of the brightness of the projector output full white screen and full black screen, and the original contrast is measured using the ANSI 16-point standard (note: ANSI standards developed by the American National Standards Association, this standard is also recognized in the industry Standard) is the ratio of the average of the brightness of 8 white areas and the average of the brightness of 8 black areas in the 16-point black and white inter-color patches.

This is because lower brightness does not affect the color performance of the projected image, and on the other hand, it is a technical enhancement to meet user needs.
Color contrast test is usually used in projection test
High color saturation can easily cause visual fatigue

When viewing user reviews, it's best to choose to include pictures (real)
Sometimes when the consumer chooses a product, the merchant often lied that this model was out of stock and instead recommended other products of the same type. When recommending products, merchants are more willing to recommend hot products and newer products so that they can make more money. However, compared with new products, old products, after the full competition of old products, the price drops, the profit rate decreases; while the new products are priced higher, this should be regarded as a trap in online shopping, need to pay attention to the purchaser.
Poor reviews can sometimes see many problems
Online shopping needs anti-fraud
Summary: Choosing a high-quality intelligent micro-projection product depends not only on the brightness setting of the product, but also on the picture quality and basic performance parameters of the product. Contrast and color saturation all affect the projected picture quality, and the product is easy to use. Sex is also very important, which is directly linked to the user's sense of experience. It is worth noting that online shopping smart micro investment products, but also to prevent falling into the business trap.
