Network era P29 portable projection phone comprehensive evaluation

Evaluation preface: Portable projection of mobile phones and projection dual function Speaking of micro projection, may be a lot of friends will be "warned", that is purely a tasteless work, in addition to the generation of carrying smart phones other add-ons at the same time can not bring The color is very vivid and saturated, so there is almost no feeling of such products as micro projection. Although, compared with fixed commercial projectors or laser projectors, the microprojection is limited by the original body, resulting in the integrated projection module cannot be used for a more powerful projection display, so the comparison will appear weak, but we It is undeniable that the portability of the miniature projection is beyond the scope of the former large projector.
Yes, it is precisely based on this portability that the micro-projection has opened up in the emerging form of the market. Of course, due to the limitations of the aforementioned projector module's airframe, the growth rate at the present stage is indeed somewhat unsatisfactory, but with the advancement of technology and the improvement of the projection module, it is believed that the future use And directions will be more extensive. Actually, when we look back at the development history of mobile phones, we can verify whether one or two, from the functional machine to the smart machine, from the flip keyboard to the touch screen on the candy bar, can be said to be a progressive process, So projection is the same - when the technology comes to micro When projection is sufficient to eliminate large-scale projections, the advantage of portability can be easily won, and it will gradually nibble around the entire market.
Perhaps the size of the miniature projection is already very small, even if it is small enough to put the pockets, it is irrelevant, but there are still friends who complain that it is an extra one. After all, judging from the current carrying habits, in addition to the smart phones in the hands, the others are burden. If you really want to think so, then there is nothing wrong with it, and this has led to the use of two-in-one applications, such as from the Shenzhen City, Pratt & Whitney Communication Technology Co., Ltd., a mobile projector and projection dual-function portable projection - Net Age P29 .
The era of P29 portable projector, the biggest advantage is that it is compatible with the strengths of both the smart phone and the miniature projection. It is truly unique in maintaining the configuration of the mainstream communication terminal while also giving more cool projection function. So, what exactly does this two-in-one portable projection look like? Take a look at the following comprehensive facts.
Appearance design: It's no different from a smart phone. The body feels quite good. The P29 portable projector has a similar appearance to an ordinary smartphone. It doesn't look like a different kind of feeling. After actually getting started, I discovered that there is a sense of presence of a three-phone, and of course, if it compares to an ordinary smartphone, it is slightly thicker in thickness. However, if you think of the ability to integrate a large-scale projector with such a complex projection module into such a small mobile phone body, it would be a good product.
It adopts a 5.5-inch 1280*720 resolution screen, and the screen color is acceptable, which will not affect the end-user's daily use experience. Body measurements size is: 159mm * 85.7mm * 25.3mm, weight is 388g, whether it is the thickness of the fuselage or body weight is basically between the ordinary ultra-thin mobile phone and the micro-projection, which just happens to support its own intelligence Dual functions of mobile phone and large screen projection.
The left side of the fuselage has a manual knob focusing, projection light bulb and outlet, the right side has a volume key, DC charging hole, card slot and hidden dual speakers, the front side has a projection button, power button and headphone jack At the rear, there is only one OTG external interface (for U disk and other external expansion).
As for the bottom of the fuselage, in addition to the bracket outside the general screw (demolition assembly is extremely convenient), also has a 13 million pixel rear camera (front 500 million pixel camera). In addition, the net era P29 portable projection of the entire body to get started feel quite good, both extraordinary smooth feel and fine matte texture, good technology.
Projection module: Easily light up 150-inch large-screen visual effects with one touch Compatible with smart phone and large-screen projection dual-function Netcom P29 portable projection, as mentioned before, although you see the product form of the smart phone, The more powerful still is the cool projection function, and this function is further amplified based on the advantage of higher portability. Or, at this time you came up with the phrase "All in one's hand and I have everything in the world." I may have believed that showing off all aspects of the smartphone and describing the sight of the audience.
Based on the application of the 0.3DLP projection module in Texas, the P29 Portable Projector in the Internet era can project a more optimized visual image brightness/contrast/power consumption while maintaining “concentration”, so it can be seen on this portable projector. A dramatic increase in brightness. RGB LED light source display technology, projection ratio of 1.47, the resolution is equivalent to the phone screen 1280 * 720, can carry out a maximum size projection of 150 inches, of course, this process requires the user to actively focus clear or not.
As for brightness, it must be something that everyone cares about most. Its brightness of 600 lumens is superior to most other brands of portable projection products, so even in the daytime indoor environment can get a good projection effect, without white or a layer of white light. This time with the inherent 720P resolution, equivalent to the viewing effect of high-definition movies, making it even more superior.
Hardware test: Terminal configuration is relatively OK. The running speed is smooth and reliable. A portable projection product, not to mention excellent projection modules, it will eventually rely on hardware to maintain, so the strengths and weaknesses of the hardware configuration are used in various ways. At the time of experience, it will be affected. Hardware cannot be ignored.
Network era P29 portable projector, running Android6.0 system, equipped with MediaTek MTK6755 eight-core processor, A53 architecture, integrated LTE CAT.6 Modem full-mode solution, support for 4G network; and integrated Mali-T860 graphics processor, support 1080P display and 1080P video playback recording; In addition, on the storage, it is configured with 4G memory + 64G capacity combination, support for 128G card slot expansion capacity, users do not have to worry about the problem of insufficient storage.
Come and run a delivery!
In the security Bunny comprehensive run points, the final score was 57,025 points, playing a normal level. Although it can not compete with the current second-tier squadron 660 processor, but also to ensure the normal smooth running of the system, in fact, OK.
Contrast between day and night: Under the bright environment, the whitish color is weakened. Optimized for excellent performance in the dark environment For projection products, especially portable projection, in most cases it is “seeing dead”, that is, there will be whitening under bright conditions. This is also a common problem that most portable projectors cannot avoid. At the same time, it is also possible to see the actual skill of a certain projection product.
Relatively speaking, the portable era of the P29 portable projector will be slightly stronger, and the dark environment will not have to say any more. The advantages of its own color saturation will be reflected, and the general white fever problem in the bright environment is also greatly reduced and optimized. So day and night projections are obvious and good.
When we see such a set of day and night projections contrasting, it can clearly distinguish the actual projection situation of the portable projection of the net era P29.
Day and night projection evaluation: The following set of pictures contrasting day and night bright environment, very clear and straightforward description of the projection gap between the two, so the dark environment of the Internet era P29 portable projection is a matter of course the effect of winning; and bright environment projection Although there is still a whitish situation, if it compares with portable projectors of the same grade, then it will be slightly better - the bright environment projection after optimization will get the maximum improvement; at a glance, you may think why the white light in the bright environment There will be discoloration, but in fact it is caused by the backlighting of the camera and direct projection on the white wall. Another thing is different; as for the dark environment, the color is excellent, it also proves that the era of P29 portable projector 100% NTSC color gamut, 100% color The ability to restore.
Color contrast: Saturation has room for improvement For color testing, it is obviously a test item that projection products often go through, aiming to make indirect comparisons between proofs and actual projections, and then to obtain the color reproduction of the projection device. The rendering ability on the display is to show whether the saturation color, the degree of coldness or warmth, and the like are offset when the large-screen projection visual effect is displayed.
For the color contrast, the simplest and most crude method is to look at the color transition test, and this is the most direct and effective! After the projection of the color transition is presented, the main explanation is given for the red, blue, and green: the transition between the most intermediate local color and color is already established. No; the green part appears whitish, the slightly brighter area expands; the red part appears the saturation is not enough, the pink area enlarges; the blue part has the partial purple existence.
Relatively speaking, the P29 portable projector in the Internet era has a phenomenon of “not in place” under such a subdivided color transition test, but this is a comparison that has been presented by the camera equipment, so this difference is still normal. Of course, there is still room for improvement in terms of saturation.
Finally, I would like to feel the contrast between the three groups of blue, red, and green images. The left is the prototype original image, and the right is the real shot projection (no adjustment, only the size of the cropped image). After the actual comparison, the comparison results of these three groups are similar to the results presented in the previous color transition comparison, and there is not much difference between them.
Experience: The portable projection of business office/entertainment and entertainment solution may not reach the top match on the smart phone or the ideal projection on the professional projector, but it is the core function of both parties, and it is also unique The portability of force is actually a big step forward. In other words, the P29 Portable Projector in the Internet Age is a solution that combines business office, living entertainment, and a good one, filling the gap in the portable projection function of the smart terminal.
With such a high degree of portability, the P29 portable projector in the Internet era is extremely useful for smartphones and large-screen projectors, and such dual functions are more prominent in outdoor travel, business negotiations, good friends, and large-screen movies. It also exerts its inherent product advantages.
In view of the Internet era P29 prototype is a smart phone, so it is inevitable that in the era of pats and pats. Through the shooting of several pictures, we can draw the performance of the P29 portable projection 13 million-pixel rear camera in the Internet era – the overall contrast is good, the saturation needs to be improved, and the ability to restore resolution in a cloudy environment is still OK.
Evaluation summary: The smart phone and large-screen projection dual-function projection is seen in the network era P29 portable projection, a technology based on smart phones and additional projection features!
The Netcom P29 portable projector, which integrates smart phones and large-screen projections, can bring about projection functions in a combined form while bringing smart phones into regular use. This is in itself a difficult task. Although the saturation and other aspects of the test process are somewhat lacking, but it does not hinder its projection (0.3 DLP projection module), 600 brightness lumens, 720P resolution, 150-inch screen effect, general screw disassembly assembly Convenient, one-button lighting projection, even highlights such as the large-capacity battery of 6700mAh, these are significant advantages in large-screen sharing, efficient operation, camping entertainment, etc. This is actually sufficient.
Of course, relatively speaking, it also needs to be improved, such as the hardware configuration can be better with the top point, the projection module can be stronger, the body thickness can be thinner and even better.
