Camping, take a 300-inch smart TV and walk together

Ninety years ago, a Scotsman named John Rocky Bird did not expect that a 300-inch big-screen TV could be trapped in a jacket pocket as people go out camping; nor did they think that TV opportunities did not have “screens” and A white wall or a piece of white cloth in your home can be the screen of your TV. Of course, he is less likely to think that TV can be so smart. However, we still have to give sincere respect to this super-geek! Because, in 1925, this electronic engineer invented a mechanical scanning television. From then on, television has changed human life. People entered the era of television, from black and white to color, from analog to digital, television has brought people a civilization era of information dissemination.
The appearance of no-screen TV has once again brought a revolution in television - TV can get out of the home, and as you go camping, relive the good old days of our childhood open-air movies. This is an extremely screenless TV Cc.
We have noticed that we have printed several LOGOs that are familiar to us on the outer packaging of this small box. This is JBL and Mango TV. Yes, this non-screen TV uses JBL's speakers internally to achieve such a good bass effect in such a small volume, but there are also drawbacks: the stereo effect is not obvious because the sound source has a "keyhole effect" if The "SRS (Sound Retrieval System)" processor is added to the audio circuit, and the effect will be better. Mango TV does not need much explanation. This is a smart TV application that can use the Internet to watch programs.
The bottom of the box also has a function description, this TV also supports 3D playback, but unfortunately does not come with 3D glasses, in addition, also has a sound mode, with Bluetooth audio decoding, if you do not see the screen, only play music is also possible.
Below the outside of the box, the words "300-inch Super TV" are indicated. In the case of a bright enough picture, it is easy to project a 300-inch large TV screen.
After opening the package, the square box that is like a large cube is seen as a non-screen TV host. There is a soft leather handle above it. This is the definition of "a TV that can be carried away."
The slide design on the front is both a power switch, a mode switch, and a lens dust cover.
Below is the speaker hole.
The overall volume is small and exquisite, built-in 20000mAh batteries, can also play 2-3 movies in the case of off the power, if it is re-audio mode, you can play 12 hours, go out camping, enough to use.
The so-called non-screen TV, in fact, is a projection + network set-top box aggregates, with the advent of Texas DMD microchip and high-brightness LED, especially the LED light source changes, so that the size of the projector is greatly reduced, Heat output can be effectively reduced. Of course, power consumption is also saved. The advancement of these technologies has made the popularity of screenless TVs a reality. There are two USB jacks on the back of the machine that can play video and audio on an external USB flash drive. There is also an HDMI interface that allows access to signals such as computers and video players. On the left is the power connector and on the right is the headphone connector. Below is a cooling hole.
The top has a touch-type operation button, the volume keys on both sides are touch type, and there are four white LED indicators for charging instructions.
The most notable is the screw holes on the bottom of the platform, so that we can use a tripod to mount the projector when camping in the wild or on special occasions. With the pan/tilt quick mount, you can use the tripod. Because the Cc TV uses an ultra-short focal length lens, when the conference room is used, it can project a big picture without using the far distance from the screen. Therefore, PTZ design is very necessary.
This is the effect on the tripod.
Now let's talk about other items in the package: one remote controller, one GP7 battery, one manual, and one warranty card.
The remote controller is similar to the remote controller of most network set-top boxes. The keys are concise and the menu keys are dual-function. Long press can call out shortcut settings such as brightness setting, focus, 3D settings, and projection settings.
At the bottom, there is also a toggle switch that uses the quick switch volume key as the focus key.
In the design of Cc, the most tedious setup of projectors in the past: focus and trapezoidal correction are all automatic. There is a distance sensor next to the lens. As long as the distance between the screens changes, the focus setting will be automatically activated and a clear picture will be obtained in the shortest possible time. There is also a level sensor inside the machine to detect the horizontal position of the machine so that automatic trapezoidal correction can be started and an undistorted picture can be obtained.
The power source is 17.5V. If you are using camping, you must be fully charged and then set off. Because in the wild, if there is no AC power source, there is no way to use a charging treasure to supplement the power supply after the battery is exhausted. Of course, the reverse is OK, we can use Cc's USB interface to charge the phone.
Internal with 16G of memory, after the system is occupied, there are about 10.5G available, for a few high-definition movies, but also enough to watch a few hours, if at home, as long as connected to WIFI, massive programs on the network, as you chosen.
The appearance is very exquisite. In use, after playing through the Internet, when it is fully charged, we play normal-definition programs and play it continuously for 4 hours, saving more than 40% of electricity (see icons).
In order to obtain the most intuitive experience, we use the other two projectors for comparison. One is the smallest mini-projector at the moment - the small magic cast, and the other is an ordinary SONY projector.
Of course, before using it, we have to do some settings on Cc's screenless TV.
After the power is turned on, the remote controller is suggested to be paired. The Cc TV uses a Bluetooth remote controller. In this way, we can control the non-screen TV in the bed in the winter. Of course, a few pages will be played using setup instructions.
After you log in to your account, you can use the built-in Mango TV.
Internally there is no built-in broadcast software. We tried to install it from a USB flash drive. We failed to succeed. However, there is a screenless assistant in the system. After installing the screenless assistant through the mobile phone, various applications can be installed. We installed Xiao Wei’s And Tencent video, so that the program is even more abundant.
After setting up, we will do a comparative test. First of all, we will describe the following environment. This is the afternoon time. In the bedroom, there is sunshine outside the window.
The three projections are all turned on. Since both LED projections use ultra-short focal lengths, about 3 meters, SONY projects a 90-inch screen, Xiaomotou throws a 120-inch screen, and Cc throws a nearly 200-inch screen. If the distance is further away, the picture can be large, but the brightness will be reduced.
Next we use these two instruments to test the brightness and noise. In order to obtain relatively objective data, the curtains need to be closed.
This is the test result of the small magic cast. In the brightest position of the screen, the measured illuminance is 8LUX. After all, the brightness of the little devil's head is only 60 lumens. In addition to 1 meter away from the machine, the fan noise is 39.6 db.
This is a screenless TV with a metre meter Cc. The illuminance is 45 Lux, and the noise at one meter is 35.5 db. In terms of feeling, in such a big picture, the environment should be darker. We have tried to project a 100-inch screen and the brightness will be much higher. It can be watched with indoor lighting.
The most powerful is still the traditional projection equipment, the SONY projection 248LUX illumination, fan noise is 45.1db, of course, the projector's lamp brightness is 2500 lumens. Of course, we can not use the ultra-thick rice screen TV and traditional projectors compared to traditional projectors using high-power high-pressure light source, destined to small size.
Now test the output through the computer with HDMI interface. The resolution of the notebook is 1920x1080. The resolution of the display screen is very good. The picture is very delicate, the characters are clear, and the color fidelity is also high. Demonstrate for the conference room. It is fully capable.
The characters are not jagged and the picture is clear. At this time, although the illuminance is only 38 LUX, it feels very bright, and the picture clarity is also very good.
This is to display EXCEL forms and WORD documents, as well as CAD graphics. However, the interior of the TV screen is actually an electronic circle test signal. This is a common graphic for us to test sharpness, grayscale, and resolution. It is called "TV. Machine's Mirror." By electronically testing the picture, you can see that both the color and clarity are satisfactory.
Of course, next we use the installed software to watch the show. The 300-inch big screen looks like a movie in your bedroom. Whether it's a ghost or a live show, of course there is also Song Bingjia. "I don't know the still picture of this uncle when he was young. How many people can recognize it?"
