Not much to say first, we first come to the ten may be the consumer most concerned about the problem, after you finish your time you can go out, remember to like it.
Ten Questions
1. What is Papa Mobile Projection?
Mobile phone projectors, palm-size, are relatively small compared to traditional micro-projections, and emphasize wireless connectivity.
2. How much is the resolution and how much is the brightness?
Resolution 854480, I really can not find the brightness, visual inspection of 100 to 300 lumens, turn off the light anyway.
3. How big is the size?
Half iphone6+, two iphone6+ thick, 1.6cm overall, square overall, long 8.5cm
4. Standby time?
Wireless connection for about one hour, wired connection less than one and a half hours, can use an external charger or mobile power.
5. How to connect?
Apple Airplay, Android and Windows Miracast, DLNA, Cable mini HDMI.
6. Is Papa Mobile Projector and Papa Pocket Theater a thing?
No, Papa's pocket cinema is a product released by Papa in 2015. Its positioning is micro-projection. Papa mobile phone projection is a new product released in 2016, and is our protagonist this time, positioning is a mobile phone projector. The difference is that the phone projection is much smaller, much smaller, and much smaller.
7.480P resolution will not be very effective?
The DVD's resolution is 480P, don't overestimate your own eyes, watching video is still good.
8. Can adjust the projection angle?
No, but so small, it is recommended to buy a mobile phone holder and adjust it.
9. Can I adjust the color temperature, brightness, contrast, trapezoidal correction?
No, it's all preset.
10. Is it worth buying?
It is recommended to sleep-syndrome patients who must be in bed to watch a few episodes of TV cartoons every day before going to bed. There are better devices that can be done on other occasions. Buy it back and look at the film chase drama, emergency show more than a slide show more than enough, do not try to copy work and web browsing on the right.
Then, the text starts
Foreword
Thanks to Aunt Zhang and the factory elephant for running this opportunity to test. I am a person who likes tossing and also has a longing for the big screen. The projector is not a fresh instrument, but in the past more was used in business and enterprise-class occasions, with the cost-effective upgrade of home projectors, while more manufacturers involved in the micro-projection short-distance projection and other occasions, Projectors increasingly replace large-screen televisions as the home theater of choice.
(I own an old figure, 3000 lumens 1080p projection at night effect, the lower left is a 24-inch monitor)
On the other hand, in addition to the continuous development of full-size projector technology, manufacturers have also been trying to plug projection equipment into a variety of electronic products to act as a screen. Earlier, there was a cottage with a projection function, followed by a projection function. Flat panel, NUC with projection function, even our Sony Dafa has also introduced a mobile phone projection product resembling a mobile power source. It can be seen that everyone is quite eager for such portable projection equipment.
In the past year, I also purchased a full-size, high-brightness, full-size projector. I also dealt with numerous office projectors. In my opinion, there are still problems with the use of projectors. These ones:
1. Brightness. This is the most restrictive condition for projectors. It can be said that the darker scene projectors perform better. Under natural light or light, even if I have a projector with a nominal brightness of 3,000 lumens, the performance is far from satisfactory.
2. Heat and noise. The core device of a projector is a large light bulb, and the greater the brightness, the greater the heat generated by it, and the fans that are commonly used for cooling purposes will generally cause noise problems.
3. Requirements for the projection screen. Of course, if the projector works well, a white wall can provide good results, but better materials and reflective efficiency can provide better results, but once the screen is placed, it also invisible fixed the location of the projector .
Therefore, at present, the projector's effect and portability is still an irreconcilable contradiction, then we take a look at the performance of this Papa mobile phone projection.
Out of the box
Open the Chang Da Ma style packaging as usual, you can see our protagonist this time, the square box, and the current mobile phone packaging is similar.
After opening, you can see the composition of the content. In the middle of the square is our ontology - a mobile phone projector, in addition to a remote control, a data cable and a charger.
Take a look at the details of the mobile phone projector, the whole thickness of only 1.6cm, the overall square, long paragraph are 8.5cm
Compared with the size of prehistoric projectors in our office, I really feel the progress of science and technology.
On the front, on the right side is the projector's core structure - where the light bulb is located, and on the left is the heat vent.
On both sides, there are power buttons, focal length adjustment buttons, and cooling holes.
The rear is the interface of the collection, respectively, micro USB port (charge), standard USB port (can be inserted U disk), mini HDMI port (for wired connection), of course, is ultimately where the infrared receiver.
Looking at the top and bottom, the top is a silver matte PVC cover with the Papa logo printed in the middle, and the bottom is empty except for 4 foot pads. It would be better if there is a small bracket for adjusting the angle.
Let's take a look at the remote control, if you have used a variety of television boxes will not be unfamiliar, so the cost of learning to get started is also very low.
There is nothing special about chargers and data cable instructors. The charging head is huge, but the parameters are not exaggerated, but I have not seen much wrong with charging my own charger.
In summary, from the perspective of industrial design, the projector body is still very good workmanship is very small, but the work of packaging and accessories is indeed a little cheap, I hope you can more carefully.
connection
Since the main product of this product is the mobile phone projection, natural wireless connection is the key. Regarding the various ways of the current wireless connection, I wrote an article in Zhang Aunt before and extracted a few sections of popular science:
1.AirPlay
Airplay is Apple's dominant wireless video transmission protocol
airPlay is a playback technology added by Apple Inc. in iOS 4.2 and OS X Mountain Lion. It can transfer video images on iPhone, iPod touch, iPad and Mac (requires OS X Mountain Lion) to Airplay-enabled devices ( Such as: speakers, Apple TV) play. Using Airplay requires an iOS 4.2 version of the device or iTunes version 10.1 or higher on a Mac computer. Video mirroring requires iOS 5 and OS X Mountain Lion.
In other words, airplay only Apple's equipment can do the source, only Apple's own equipment and authorized equipment can be used as a terminal, the transmission technology is based on wifi, so the quality of the network directly affects the video quality, but because of Apple's policy, it has its limitation.
2.WIDI & Miracast
The full name of this technology is Intel WirelessDisplay, the Chinese name is wireless high-definition technology. It is dominated by Intel Corporation, and Intel Core and Wireless Network Cards are required for use. Terminals need to support this protocol or purchase additional equipment. The network uses wifi derect (wifi peer-to-peer) technology—that is, no LAN connection to the Internet.
Aside from the confusion of technology alliances and complex patent authorizations, Miracast can be seen as an upgraded version of WIDI technology, also using wifi derect technology, and adding various features, similar to Airplay. Added support for Android phones.
Both Miracast and WIDI are fully compatible with the transmitter and receiver. If there is a mobile phone that supports the Miracast protocol and the TV supports WIDI, the two are fully interoperable. If it is a WIDI ultrabook, and a TV that supports Miracast, the two can also communicate. Since WiDi/Miracast does not require Wi-Fi chips to make hardware changes, Wi-Fi chip makers can relatively easily add it, and the cost is relatively low, so this solution is the largest market share of wireless high-definition video technology.
It can be seen that the most popular wireless connection protocol currently used on ios and Android devices is Airplay and Miracast that are supported by our Papa mobile phone projection. In addition, support for mini HDMI connections is also compatible.
The measured text editors are somewhat different from the original ones. It may be that the typesetting is not very good-looking, and I am sorry to say that you are the spectator.
First boot, press and hold the only button on the body to open, and see I fire laser, biubiubiu~
First, let's demonstrate the effect of the Apple device. Immediately after the projector is powered on, it is the wireless connection guide page.
At this time, the mobile phone needs to connect with Papa's own wifi to match it. After a short wait, it can be found on the Airplay page of the mobile phone. After selecting the image, select the image, ok, and simply get it. It is that simple.
But this time we can't use wifi on mobile phones. How can this be so expensive? This is an advanced setting that we can use to enter the Papa phone projection by scanning code. After entering, find the LAN wifi you are talking about, connect the projector to wifi, connect the phone to the same wifi, and you can continue to use it.
Then try the mac connection, because Apple devices all support Airplay, so the connection is as simple, as long as your LAN segment Airplay device, the status bar will prompt the Airplay window, click on the link.
As for Android devices and Window devices, due to the inconsistency of hardware, the effect of wireless connection at present is still uncertain. In theory, Miracast can achieve the same effect as Airplay. After the equipment I tested, the possibility of windows computer connection is very low. In addition to the surface pro3 can be connected, I have failed other computers; the situation of the android device is better, But there are devices that cannot be found (such as my Nexus6). This is not a problem with this projector, but it is a deficiency of the miracast protocol. Therefore, if you want to buy this device, you should try out whether the mobile phone can be supported on devices that support Miracast technology such as the Xiaomi box. buy.
If you can connect, the connection will be very simple, without any settings, as long as the boot state, select the screen image in the connection, and click on the connection "PaPa-95C" to connect successfully, the connection process is very simple and convenient.
As for the wired connection, it is very simple, as long as the use of mini HDMI cable / MHL line /Lighting to HDMI line, connected to the playback device, you can provide stable and high frame rate projection images without delay. For example, when you are traveling with a PS4, this small projector is a very lightweight screen selection.
What is also mentioned is that the projector can still be used directly from the smart device. The official provides a minimal degree of system integration in the machine and can directly play videos and pictures in the U disk. However, it is worth mentioning that U disk does not support exFAT format.
display effect
How the display effect is undoubtedly the most important part of the readership of this article, the mini size of the projector does make people very worried about the quality of the projection display. As mentioned before, the effect of projection is nothing less than the size of light and projection. Let's test the effect separately.
Environment I chose to be on the wall of the first small office we normally meet. The projection size is about 60-70 inches. The time is in the afternoon. The environment is cloudy. If you don’t turn on the lights, it is very dark. Look at the display. effect.
Then turn on the fluorescent and look at the effect
It can be seen that if the interference of the light source, the projection quality will drop a lot, but if in the dark light environment, the projection quality is acceptable, whether it is brightness or color reproduction are more true.
Below to a few mobile phones to play the video of the b station
It can be seen that the sharpness of the image is acceptable, and the subtitles are somewhat blurred because of the reason that the wireless transmission refreshes the frame rate, and the effect of watching with the naked eye is much better than that of the picture.
Let’s take a look at the effect of the movie and choose a hot preview of the US team 3
It can be seen that the viewing effect is still very good, and the effect of watching movies is extraordinary.
Then we will test the projection distance again. The original reference is about 70 inches from a distance of two meters.
(projection distance 1.5 meters, size 40 inches)
(projection distance 2 meters, size 70 inches)
(projection distance 3 meters, size 100 inches)
As shown in the above figure, the brightness of the image sharply decreases as the distance increases, and the degree of color reproduction is also distorted. After 120 inches or more, it is almost unacceptable. Although the white wall has poor reflectivity, it should be able to achieve better results on the professional screen, but this deviates from the original intention of mobile phone projection. So I think the projector's recommended use distance is still about 2 meters is better. At a distance of two meters, the light off environment is not exactly what you put on the bed before going to bed.
By the way, the sound effects of official propaganda should be mentioned again. It is not easy to forget to integrate sound units in such a small body, but the effect is naturally the standard of mobile phones. Do not expect too much.
Use summary
For this device, I feel like a dessert in my life. It is not indispensable for it. It does not replace the status of dinner, but it always brings sweetness to life. Imagine a young man living in a rental house. Buying a big-screen TV is not a good choice in terms of economy or moving home. Watching video on a mobile phone is not only a sore arm, but also a cold in the winter. There is such a device in the bed. Head, watching a set of two episodes of animated drama or variety before going to bed is a way to improve happiness. Although there are many deficiencies in this product, we see the trend of creativity and the future. I believe that with the development of miniaturization of projection technology, we can bring a better experience. What? Do you speak VR devices? Wearing a movie theater? Buddy, you must be single.
Advantages: small and exquisite, rich connection
Disadvantages: low projection brightness and resolution, small adjustment of the focal length of the dial, not easy to adjust, no self-supporting bracket is not easy to adjust the angle
