Nowadays, young people still buy houses in small units, but in small apartments, there may not be a giant screen TV, but there is definitely a place to put a small smart projector. Compared with the TV, the home projector can be much more convenient to use, no need to install, only need a flat wall, you can also move at will, in the living room sofa, study, bedroom can be immersed in the home theater, not limited by time and space, want to move where you want to move. For the young people who rent a house, the projector is more indispensable, a small projector can not only improve the quality of life, but also be carried at any time to meet the needs of economics, more importantly, in the case of sharing can not leave the bedroom to have a large screen video, to bring more happiness to young people.
This also explains why the sales of home projectors have shown a stepwise growth in recent years, and the consumer demand space in the entire market is gradually increasing. In people's traditional impression of the projector, compared with the TV's various almost such as poor picture quality, low brightness, short life, adjustment trouble and other issues, with the rapid development of projector technology, have been solved, but the color reproduction of picture quality is more difficult technical.
Take the two new products released recently, nut J10S and Dangbei F5, the brightness data of these two projectors is excellent, Dangbei F5 is 2800 ANSI stream brightness, nut J10S is 2400 ANSI stream brightness. So from the perspective of picture quality and color reproduction, how do they perform? In particular, home projectors are limited to the working principle of projection, and products on the market often use three design goals: sacrificing brightness to preserve color, sacrificing color to maintain brightness, taking the median value to find a balance, different design concepts will lead to great differences in the actual performance of the product.
Portrait off the light contrast
Through the comparison of the actual projection effect, it was found that when the Bei F5 is actually a product that sacrifices the design concept of color brightness preservation, although high lumen data has been obtained, there are more prominent selling points in product promotion, but the actual picture effect will appear color cast and overexposed, the color is not accurate, the brightness is no longer useful, but it will always feel that the color is dim.
From the details, the overall color rendering of the nut J10S is relatively high, although the brightness is not as high as the shell, but the design goal of taking the middle value to find a balance is not excessively pursued. Here we have to mention the nut J10S Leica color grading, it is understood that this projector is the nut laboratory team and Leica vision technology experts jointly set up a technical expert group, optical technology communication, many times for image quality tuning, and finally ensure that the product in the reach of Leica color standards, in the picture quality at the same time, the color accuracy is more accurate.
In addition to the difference in picture quality color, in the process of booting, a big difference was also found, that is, the automatic keystone correction function. According to the calculation of the stopwatch, the nut J10S only takes less than 2 seconds to complete the sensorless trapezoidal correction, no screen flashing, no auxiliary diagram, and the adjustment is completed in one go.
When the Bei F5 is not so smart in terms of automatic keystone correction, the whole process takes up to 10 seconds, which includes black and white checkerboard reflections, screen flashing, grid-by-frame adjustments and other actions, that is to say, if you buy it, you need to be flashed several times every time you turn on the machine, waiting for more than ten seconds.
Fundamentally, the difference between the two is that in addition to the processor chip, the Nut J10S is also equipped with an independent display chip i-Chips, which can quickly process special images, realize the side projection 3D function and the side projection low latency function, and at the same time release a part of the pressure for the CPU, so that boot and adjustment are faster.
Finally, let's summarize:
1, when choosing a projector, do not pursue a single parameter of high value, to comprehensively measure;
2. When the brightness is too high, first of all, you need to pay attention to whether the heat dissipation performance can keep up, and then check whether the picture quality has color cast overexposure;
3. In terms of picture color, self-developed technology or joint technology will give the projector additional blessing;
4, the dual-chip design will make the projector run faster, with more intelligent functions;
5, timely product description, the same function, the performance in actual use will be different (such as automatic keystone correction).
Therefore, everyone should not be anxious and blind when purchasing, but should make more comparisons, it is best to find other product evaluations of the brand, such as nuts and the overall evaluation of the previous generation of products of the shellfish, have a certain understanding of the brand, and also improve the judgment and cognition of the new product. Finally, the author would like to say a word to the projector brand manufacturers, now consumers are not as "good as before", only come up with "real technology", so that the new product in the performance configuration "real upgrade", the market will recognize you, otherwise, even if there are short-term benefits, it is not a long-term solution. In this regard, looking at the various brands of mobile phones, it is a good example.
