With the rapid development of micro projection chips, projection devices are no longer limited to the desktop market. Portable projection devices with built-in batteries are gradually emerging, including not only portable projectors with a single function, but also projection mobile phones with built-in smart phones and projection devices. Yingying is one of the earliest companies focusing on projection mobile phones, Last year, it launched its first projection mobile phone, and now this product line has iterated to the second generation product. In addition to its success in the market, the company is also actively developing a younger market, and VM3C is one of the representatives. Let's take a look at the changes of this new projection mobile phone.
Unpacking and appearance
Yingying VM3C projection mobile phone uses the usual soft PU leather packaging box of Yingying. This time, the black litchi grain PU leather is used. The leather often represents the business style. Such packaging also indicates the product positioning of the machine to a certain extent.
The inner packaging adopts drawer design, and the packaging interface is pasted with a shadow seal. The side packaging can be opened only after the seal is torn off. Accessories include charger, data cable, card pin, etc., and a velvet bag for carrying VM3C projection mobile phone.
When the fuselage comes into view, the first impression is that it inherits the consistent design style of the fuselage. The fuselage continues to use the combination of special leather plastic+metal materials, but this time it focuses on young and energetic color matching,.
The fuselage adopts the color contrast design, and the frame around the fuselage is consistent with the back, which makes the screen form a design surrounded by color, and the color is more abundant. Although the color matching is lively, there is still a certain business style on the whole, especially the customized system and the chin wrapped with special leather and plastic.
The design of the top of the fuselage is relatively rigid, angular, and quite tough. The fuselage is factory fitted with a protective film, which is very considerate. The machine is equipped with a 5 megapixel front camera, which is located in the upper right corner of the body. The LED indicator is hidden near the earpiece.
The back of the fuselage is also made of special leather plastic, which is used in photography. Although it is also leather texture, when encountering the warm red color matching, the business style turns into a passionate fashion. The red and black matching is also one of the most classic color matching.
The 13 million pixel rear camera is used, and the light below the camera is a fill lamp. The camera is also wrapped with special leather plastic material around the camera. The edge treatment is relatively meticulous, without unnecessary wrinkles.
The edges on both sides of the back are sewn with sewing lines. The sewing lines are in the same color as the back cover. The workmanship is solid and adds a sense of symmetry to the composure. The lower part of the fuselage is the loudspeaker opening, and the double opening can avoid the loudspeaker being covered to some extent.
If the back cover is both classic and fashionable, the aluminum alloy frame, plus the exposed screws on the body, is somewhat mechanical, giving a very durable feeling.
In addition to the common volume button on the left side of the frame, a special focusing wheel for projection is also added, which is responsible for manual precise focusing. At the same time, it is equipped with an automatic correction function. The official data is that the projection image is shifted 5 degrees up and down, and the correction range is plus or minus 40 degrees.
There are two rows of openings on both sides of the frame in a symmetrical position. These two rows of openings are designed to solve the heat dissipation problem of the projection module. They can not only serve as air intake, but also assist in heat dissipation. After all, unlike ordinary mobile phones, the projection module has always been a major heat generator.
The design of the right side of the frame is more complicated. Similar to the left side, there are two buttons, but their functions are quite different. The button at the bottom is the power button, and the button at the top is the exclusive "projection button" for one button to start the projection function, which is also its special feature. The bottom of the button is the SIM card slot, and the surface is black. The top of the frame also has an air inlet for auxiliary heat dissipation.
The bottom of the body is relatively simple, with only 3.5mm headphone jack, Micro USB interface and microphone opening.
The most attractive thing on the top of the fuselage is the projection lens, which is also the essence of the whole machine. Since the projection light source is relatively hot, a heat sink is also added at the top, from which the heat generated by the projection module is dissipated. In order to solve the problem of large heating of the projection module, many auxiliary cooling designs have been made in the heat dissipation of the shadow.
Speaking of projection mobile phones, the core competitiveness is of course the portable projection function. Although there are portable projectors with built-in batteries, the size is still high. In contrast, the projection mobile phone VM3C is also one of the smallest portable projection devices at present, and it is also a smart phone function, which can be operated by touching the screen, It is better than projector in ease of use.
Two color picture appreciation
In addition to the red VM3C, a blue color that can be combined with red to form a CP has also been introduced. If red is still calm, then the blue color is completely youthful.
Red and blue are also one of the most classic combination colors.
Red like fire, blue like ice, one warm, one cold.
VM3C has no lens cover and can be used immediately after opening projection.
The launch of VM3C in Cinema is obviously intended to enter a younger market, so it has also joined such a bright color combination. However, in terms of system UI, it still needs to be younger. The system UI carried by VM3C is still biased towards the luxury business style.
Projection effect
Compared with the portable projector, the VM3C projection mobile phone is smaller in size, but its small size does not affect its functionality. It uses the DLP projection module and OSRAM LED light source provided by Texas Instruments, which can provide 100 lumens of brightness, which is already at the same level as most portable projectors with built-in batteries. Most of the current smart projection mobile phones can only reach 60 lumens. In addition to its advantages in brightness, it can also provide a projection picture with a maximum diagonal of about 100 inches. Now let's take a look at the real projection effect.
In the test of color performance, it has a good performance in most scenes. The color expressiveness is fairly good. The color reversion is at the normal level, and the overall color is slightly blue, but the color tendency is more pleasing. In the normal conference room environment, the pressure of using it is not great, and only a white wall is needed. After all, it is a portable projection device, The brightness will be slightly difficult in strong light.
In this group of samples, compared with the original film, the projection color is still slightly blue, which may also be the tendency of the incoming film in terms of color blending orientation. Often highlighting red and blue will make the picture look brighter. For a projection mobile phone, it is good to do this. In terms of clarity, the performance of some details has also reached a sufficient level. Text and pictures can be clearly displayed, and the projection for business travel can be basically satisfied.
In the final high-resolution video test, the color saturation of the VM3C screen was good. Many test scenes provided more brilliant color performance. Although the red color still seemed a bit excessive, the overall flaws did not hide the flaws. It is certainly possible to achieve such a projection effect in such a small body.
summary
As a device that takes into account both mobile phones and projectors, VM3C is the second generation of projection mobile phone, which has improved in portability and ease of use. In particular, its body size is much smaller than the original product. Although it is not the smallest portable projection device, it has made a good trade-off between projection effect, heat dissipation, endurance and body size.
In terms of projection, the VM3C projection mobile phone is equipped with the DLP optical module solution provided by Texas Instruments, which can provide about 100 lumens of projection brightness, color saturation and picture definition are also good. Under normal conference room light, the pressure is not great, and the emergency projection for daily business trips is basically enough. After all, it is not too much for large projectors. In terms of projection experience, since VM3C is a smart phone itself, it is more intuitive in operation and can be operated directly on the screen, such as picture switching, PPT page turning, etc., which is simpler and more convenient than remote control operation.
VM3C projection mobile phones continue the brand's consistent design language, fashionable and colorful shapes, which are rare in today's stereotyped smart phones. In addition to the practical portable projection function, it has become a unique presence in the industry, which is why it can occupy a place in the fierce market competition. It is hoped that with the development of micro projection modules, InShadow can bring us more lightweight projection mobile phones in the future.
