But it doesn't mean that projectors don't have good solutions. With the breaking of technical barriers and the reduction of cost, projectors based on tricolor laser technology began to enter the home market. Tricolor laser technology has the advantages of higher brightness and color saturation, and has now become the first choice for middle and high-end projectors.
When it comes to laser technology, we have to talk about the brand Hisense. In this field, Hisense has been settling for 16 years and has become the maker of international laser standards. It has 1 national R&D center and the world's first ambient light laboratory, and holds more than 2,030 patented laser display technologies, and won the CES award twice, which plays an important role in the industry.
Relying on the advantages of laser technology in parent brand, its brand Vidda launched the 4K three-color laser projection C 1S, with the vision of bringing young people a cinema-like viewing experience.
Why a tricolor laser?
As we all know, laser is the light source with the highest color purity at present, and tricolor laser is the best solution to maximize the true color of projector.
Because monochromatic laser has only one blue light source, different color states can be achieved through the fluorescent color wheel, so the color display will be worse. Three-color laser does not need fluorescent color wheel, and its color performance is closer to the real natural color seen by human eyes, and its imaging effect is better.
The Vidda C 1S sent for testing this time also adopts tricolor laser technology, which is believed to make people shine in overall performance. The author will show you this new product.
First of all, the shape of C 1S is very square, and the overall design concept is also based on simplicity. The front of the projection lens is surrounded by metal wire drawing technology, and there are ToF sensors and cameras on both sides of the lens, which can realize the functions of automatic image entry, automatic focusing and obstacle avoidance.
The upper part is the operation area, including start key, pause key, volume+/-key and indicator light. Four small round holes are microphone openings for sound.
JBL logo can be clearly seen in the lower right corner of c1s. I learned from official website that this product adopts JBL customized audio and is tuned by Harman Kardon's golden ear. I believe there will be a good performance in sound quality.
On the back of the product are power supply, two USB, two HDMI, optical fiber, earphone, network and other interfaces in turn, and there is an infrared receiving device above the circular decorative button.
Image quality measurement of three-color laser
C 1S adopts a new generation of three-color laser engine and is equipped with a 0.47-inch DMD micro-mirror chip of Texas Instruments, achieving 4K ultra-high definition resolution. Even on the giant screen of 100 inch, the image is very fine and clear.
At the same time, C 1S has been tested by the National Radio, Film and Television Inspection Center, and its brightness reaches 1600ANSI, which is more convincing than many products with nominal high brightness on the market, and the brightness is truly "not fake".
I was surprised by the performance of Vidda C 1S when I opened the curtains in the living room during the day. The outline of the whole space flight is clearly visible. Although the dark details are not well displayed, the bright parts are very well displayed. After closing the curtains, the picture effect has been improved, and the dark details have also been displayed, but it is still slightly different from the night scene effect.
It can be seen that the brightness of 1600ANSI of C 1S is still very strong, which solves the problem that you can't see the projection during the day, but it may be more suitable to use high brightness in combination with night.
In terms of picture definition, C 1S increases the number of laser chips to 18, and is equipped with a 0.47-inch DMD micro-mirror chip to make the picture definition better. As shown in the above picture, the local details of the picture are still delicate after being magnified twice, and the performance is still very good.
As mentioned earlier, C 1S is based on three-color laser technology, and the actual brightness is obviously improved. At the same time, the color gamut is also improved to110% bt.2020. Combined with the self-developed OPT achromatic technology and integral chain uniform light integration technology, the color control is more accurate. Let's put some actual 4K pictures and videos to see the effect.
Note: Due to the shooting reasons and the compression of pictures and video GIF pictures, the display effect does not represent the actual performance of C 1S, but the actual perception effect will be much better.
First of all, the performance of static pictures, we can clearly see that the color display is very strong, and it is true that under the three-color laser technology, the pure color effect can be truly restored. If it's not a projection, someone will definitely think it's the original.
In addition, we can also feel the high contrast of c 1600: 1 in the starry pictures. The dark details are deep and the bright parts are transparent, which shows the details of the starry sky incisively and vividly.
Next, let's enjoy some high-definition picture proofs and 4K video GIF pictures:
I have to say that the ultra-wide color gamut of 1 10% BT.2020, the high color depth of 10Bit 10.7+007 billion colors, and the high color brigadier of Δ e ≈ 0.9 of Vidda C 1S have brought us into high image quality.
In terms of speckle removal technology, Hisense has the largest number of 102 patents in the world, and this C 1S is a brand-new multi-dimensional dynamic speckle removal solution. After practical experience, from 2 or 3 meters away, basically no speckle can be felt. Vidda C 1S can be said to be doing very well.
Secondly, in order to reduce the image noise of the three-color laser projector, C 1S also developed a microcrystal anti-noise algorithm, which deeply optimized the flip timing of DLP micromirrors and achieved 99.9% noise suppression effect. After comparing various DLP projections, we also find that the noise suppression of Vidda C 1S is really first-class level.
Cinema-level immersion experience
We went to the cinema to watch movies. In addition to the high-definition giant screen quality, the overall sound effect of the cinema is also a highlight. In order to make C 1S have a cinematic immersive experience, JBL HiFi audio was specially customized and passed the training of Harman Kardon Golden Ear team. Equipped with two 10W high-power speakers, the maximum sound pressure can reach 90+dB.
In order to achieve the cinema-level effect, the product has also added a Vi-balance bass enhancement module, and the bass dive can reach 55Hz. The subwoofer was completely released when playing the footage launched by the interstellar Cooper rocket, and the volume was only a quarter. The whole living room is covered with surging sound, and the sound also feels coming from all directions, with a strong sense of immersion.
And C 1S also supports Dolby +DTS double decoding, DTS virtual X 360 surround sound, Dolby DAP cinema-level immersion sound and viper sound. Even if you don't watch movies and use C 1S as a Bluetooth stereo alone, the effect of listening to music is also very good, especially the sound is very round, and the sense of separation between sound and musical instruments is very strong, so you can feel a good sense of space.
Other characteristics and advantages of Vidda C 1S 4K three-color laser projector.
Compared with LCD TV, the projector does the least harm to users' eyes. And C 1S has passed the TUV low blue light eye protection certification, which reduces the harmful blue light band from the source, realizes "0" harmful blue light, and better protects viewers, especially developing children.
In addition, C 1S also provides global eye protection, which will automatically reduce the brightness when human activities are detected, reducing the stimulation of light sources to human eyes.
In addition, C 1S is more versatile than TV sets and can be moved at will. In order to reduce the debugging work of users changing scenes, it can also carry out high-precision autofocus and intelligent automatic keystone correction, and the correction and focusing speed is very fast. When the projection is blocked, it can also automatically identify and avoid objects such as switches and bookcases, so that the picture is always intact.
abstract
Although Vidda is a young fashion brand, it relies on Hisense's strong technical research and development strength to make its products have leap-forward performance, of which C 1S is the representative. In practical use, C 1S broke the ceiling of home projector with three-color laser technology, and improved the brightness to 1600 ANSI lumens, showing the image quality performance comparable to that of organic light-emitting diode technology, which really made users shine.
In addition, the blessing of black technology such as speckle elimination, achromatic color reduction and noise reduction also shows Hisense's technological advantages in the laser field. C 1S has also been upgraded to JBL HiFi audio. Through the adjustment of Harman Kartonkin's ear, the user realized his dream of owning a laser cinema at home.
Finally, I believe that after Vidda enters the intelligent projection industry, 4K+ trichromatic light technology will be more and more accepted by users, and it can play a leading role in various scenes such as home and office, and become a dark horse in this industry.
