What do you think of the initial launch price of the ultra-short throw projection JMGO O1S? What features and technologies are worth paying attention to?

JMGO Projector has launched its first new product since its investment, the JMGO O1S ultra-short throw projector. Compared with the JMGO Ultra Short Throw 01, the O1S projector brings major upgrades in several aspects. You deserve it. . The most beautiful feature is the 120% NTSC color gamut coverage, 1200ANSI brightness, and 85%+ uniformity. As an ultra-short-throw projector, the JMGO O1S has a self-developed LED ultra-short-throw optical engine with 1920*1080P FHD resolution. , making the image distortion rate of JMGO O1S reach <1%, far surpassing the ultra-short throw FHD optical engine of similar products in the industry, and once again refreshing the product image of ultra-short throw LED projection. A relatively good home projector can not only bring a good audio-visual experience to users, but also give people a sense of quality of life brought by smart homes.

I feel that this is an entry-level hexagonal warrior. The entry-level price is 3,499 yuan. The ultra-short throw, brightness, image quality, Dynaudio tuning, and system alone may not be outstanding, but comprehensively For this price, it's really awesome, master of balance. Especially the ultra-short-focus lens, image quality, and brightness are all related. Clicking on each skill point in the right position is really a test of the manufacturer's technology

You have to ask me about nuts. What impressed me most about the O1S? I would definitely say the optical engine design. The optical engine is the core of the projector. To a certain extent, it can be said that buying a projector means buying an optical engine. Although the 01S is an entry-level projector, it can do this. Balance shows that JMGO has outstanding optical and mechanical design capabilities. Today I will only talk about one point. Just being able to achieve 1200ANSI lumens with 0.23 DMD is amazing. Just like the CMOS of a camera and the engine of a car, the optical engine of the projector determines the level of the projector. 01S is a DLP projector.

The LED light source reflects the signal through the DMD (digital micromirror device) and then projects the image onto the screen through the lens. In between, the DMD chip and lens chip set need to be considered. The design and the heat conversion of the LED light source are the most testing aspects of the manufacturer's strength. Let's talk about it one by one.

Let’s talk about the DMD chip first. If the optical engine is the core of the projector, then the DMD chip is the core of the optical engine. We can regard the DMD chip as a "mirror". The more light the mirror reflects The brighter it is, the size of the mirror is the area of ??the DMD chip. Currently, there are three mainstream DMD chips on the market that support 1080P: DLP4710 (0.47DMD), DLP3310 (0.33DMD) and DLP23ONP (0.23DMD). Those using 0.47DMD are all high-end products, mainly 0.33DMD and 0.33DMD below 5,000 yuan.

0.23DMD, DMD determines the optical machine. overall design. Once the DMD chip determines the light source, the light source is basically determined. Let’s continue to return to the previous optical-mechanical structure diagram. In a DLP projector, the red, green, and blue LED light source array is the source of the projector’s brightness. Light and heat are a pair. The Lisheng brothers are therefore also the main source of heat.

I checked TI’s data and at 56°C, the maximum brightness that 0.33DMD can withstand is 800 lumens, while the maximum brightness that 0.23DMD can withstand is 500 lumens. The higher the lumen, the stronger the light. The more heat there is, the more heat dissipation space is required, or higher heat dissipation efficiency. This time, the JMGO O1S uses TEC semiconductor heat dissipation technology. How can I put it, it is like installing a mini air conditioner specifically for the LED beads of the light source. It dissipates heat in a targeted and precise manner and solves the biggest obstacle to the full power Q operation of the light source. It directly raises the ceiling of 0.23 DMD brightness. Basically, within 5,000 yuan, there is no ultra-short throw projector brighter than JMGO O1S. Some people may ask, since the 0.33 DMDM ??can achieve higher lumens, why do you need to force so many technologies on the 0.23 DMD?

Don’t forget that the Nut O1S has an ultra-short throw. An ultra-short throw lens is like a camera's wide-angle lens, which can produce larger-format images at the same distance. If you want to achieve this, you must first work on the lens. An ordinary projector lens only needs about 8 lenses, while an ultra-short focus lens requires a combination of more than 14 lenses, which also includes more difficulties. Larger aspherical lenses and freeform mirrors. To put it simply, the optical path design is more complex and the volume is larger. What is the difference in volume? The volume of an ultra-short throw lens at the same DMD size will be about 20-30 times that of an ordinary projection lens.

As a home appliance blogger, I have been following the Nut Smart Wall O1 since its launch. The Nut series, from O1 and O1Pro to the now launched O1S, shows targeted upgrades for different consumers. O1Pro is suitable for people who have higher requirements for picture effects, while O1S upgrades on the basis of O1 and improves the price/performance ratio. It is very suitable for those friends who repeatedly looked at the Nut O1 when it was launched and wanted to buy it but were hesitant.

The functions and technologies of this version of Nut O1S are remarkable.

The functions have been upgraded a lot, the lumens have been increased to 1200ANSI, the noise is lower, it is equipped with a new remote control and nut racket function, the new WiFi chip makes the connection more stable, supports full-time voice, the bass performance has been enhanced (minimum 55Hz), and the picture flattening algorithm has also been improved Upgraded to the Dewarping 2.0 algorithm, the success rate of eliminating screen ripples will be higher. Nut is worthy of being the leader in the domestic ultra-short throw projector industry. While the price is stable, the technology can also be praised.

Of course, the most noteworthy thing is Nut’s original companionship model. In addition to being able to watch movies for one or two hours a day, this series of projectors can also create a diverse home space. The Luna OS dual mode is its biggest highlight. And short throw distance and ultra-low noise. It makes this model more portable and perfect, and can be blended into the home environment silently.

In the previous version, after turning on the companion mode, the Nut Projector appeared. It can project pictures related to information, weather, and time, and it can also project dynamic pictures when playing music, materializing the beating of notes, and watching them in a daze while listening to music. It is also a special experience that Nut O1S adds. The four companion modes should be the highlight of this product upgrade. With the addition of the original companion mode, the functionality of the projector becomes much richer. Turn on the personalized wall or play music, then turn off the headlights, invite a group of friends to come to your home to sing karaoke for a few hours, and play a few wild songs. It will definitely be an unforgettable leisure time in the busy life.
