#100mw laser pointer

TV screen experienced from CRT to plasma and then to the LCD era after the change, the recent long period of time seems to be some stagnation, subject to the LCD itself, the principle of light restrictions, size, power consumption, technology and other aspects are close to The IFA exhibition held in early September seems to give us the answer, many TV manufacturers to market blue laser pointer TV, which Hisense is released the world's first DLP ultra-short focal length 4K Laser theater TV, caused a sensation in the industry is not small. The other domestic brands such as Changhong, TCL is also synchronized to force the laser TV, laser television market in 2016 can be lively exception.

Hisense as a leading domestic appliance enterprises, this year began to force the high-end large-screen market, especially in this year, with ULED's strong performance, Hisense 55-inch and above the high-end TV market share has exceeded Samsung to become the big screen high-end new king ; According to the data in July, Hisense laser TV has occupied more than 85-inch large screen 49.64% market share, it can be said is the undisputed industry NO.1! Hisense laser TV has been developed to the third generation, New addition to the appearance and performance to further strengthen, the resolution is raised to the 4K level, bringing the ultimate viewing experience. In addition, the latest 4K laser TV What are the different? Today, this new product came to our evaluation room, the following to send you a detailed evaluation.

I believe most people still do not understand the concept of laser television, so here I first briefly, laser TV simply and the principle of the projector is similar to this technology to first image signal after digital processing, and then again Projecting light through a series of complex lenses. It is based on TI (United States Texas Instruments) developed digital micromirror device - DMD (Digital Micromirror Device) to complete the visual digital information display technology. Specifically, the DLP projection technology uses a digital micromirror (DMD) chip as a key processing element to achieve digital optical processing. So in the light-emitting principle, the 20000mw laser pointer TV and traditional TV there is essentially the difference between the traditional LCD TV is illuminated by the backlight, and liquid crystal molecules to achieve image deflection display, and laser TV is the light projected onto the media (such as walls, Curtains, etc.), through the reflection of light to the image transmission to the human eye, and in a very short physical distance of 100-inch large screen projection.

Now that we know the principle of work, we can generally outline it compared to traditional TV some of the advantages of the first laser light source life is much longer, the brightness dropped to 80% of the previous almost 50,000 hours; followed by brightness High color gamut, Hisense 4K laser TV official nominal brightness up to 3000 lumens, color gamut coverage of 116% of the NTSC, compared to OLED and quantum dot TV is even better. Many people will say that the current price of LCD TVs have been so low, why Hisense also adhere to push the laser TV? In fact, most people's needs are only 60 inches in the following specifications, this is not the laser TV to target the market. More than 80-inch large-screen TV, the price has been high, and the success of laser TV on the picture quality comparable to LCD TVs, more importantly, the price is only the same size LCD TV 1/3, for the big screen display with To a new cost-effective solution.

At the same time Hisense 4K laser TV also broke through its three major technical difficulties: First, the use of high processing power optical engine, its processing power than 2K laser TV products increased by 300%, so that 8.3 million beam of fine control, to achieve 830 4K laser TV need high-resolution lens design, Hisense 4K lens to achieve the optical resolution of 186 per millimeter beam; third, 4K laser TV manufacturing to achieve micron-level material control accuracy and the lens Installation precision, Hisense 4K 10000mw laser pointer theater TV using a high-precision manufacturing process, machining reached a limit of close to 10 micron accuracy, the lens mounted precision of 5 microns, the error is less than a hair diameter of 1 / These together have contributed to the Hisense laser TV is different from other products of the unique advantages.

Hisense 4K laser TV, including the screen, host, stereo three parts, which is part of the screen is 100 inches large imported Fresnel passive bionic screen, rare earth technology integration of rare metals, such a large screen also has a very narrow border , Really brings the immense shock of the presence and immersion. Of course, the biggest feature of this bionic screen is its soft viewing effect, it overcame the problem of traditional TV stroboscopic, natural and comfortable, but also shield the ambient light, and projection is different in the bright light can also watch, And the color performance better. Hisense 4K laser TV is equipped with two remote control, one is to operate the video playback smart remote control, the other is to control the audio remote control, they do not interfere with each other, holding is quite comfortable. Intelligent remote control and Hisense TV's consistent, mellow, full of pebble shape, fine skin touch, can let you put it down. It also comes with a fast-switching button, but also can be customized in the system a key direct function, speed, minimalist control experience to meet all family members entertainment needs.

Due to the different light principle, we can not use the test of ordinary television test equipment for testing. So we specifically use the projector test standards for testing this product, the test link, including objective data and subjective perception of two parts, including the objective test part of the maximum brightness of the product we tested, that is, the projector in the brightest mode Brightness, contrast, light bulb mode are adjusted to the highest) of the average brightness of the screen. From our actual test results, Hisense 4K laser TV's maximum brightness reached 6400 lumens, has greatly exceeded the nominal value. In order to better display the quality of the product, we will put it together with a common LCD TV to do a comparison, you can see Hisense 4K 3000mw laser pointer TV color reproduction better treatment, the color is more true nature, and LCD TV clear image The treatment is too rich and gaudy, the color has been distorted. At the same time because of the 4K resolution, so before being criticized for more details of the part also did not strive.

For the laser TV, there is no light leakage occurs, light control is its inherent advantages. In the display of all black, the host is not projected light. Of course, contrast performance is significantly better than ordinary LCD TV, Hisense 4K laser TV also supports HDR technology, we see the following chart in the HDR format video playback, bright and dark contrast is very obvious, Guan Ying artifact title can be well deserved . Dynamic picture clarity is also one of the advantages of laser television, the following test film real shot you can see, the edge of the house is very clear, through the window, you can clearly see the branches of the peripheral branches and the passengers inside, and there is no Smear or virtual phenomenon, significantly better than the ordinary LCD TV. Test process, the power of the 100mw laser pointer TV is maintained at 400w or so, is significantly lower than the same specifications of the LCD TV, the performance of energy-saving fairly well. We can see the true color of nature, has been comparable to Japan and South Korea high-end LCD.

Beautiful, simple, easy to use has been a sign of Hisense VIDAA system, Hisense 4K laser TV also equipped with Android5.1 based on the development of VIDAA intelligent system to poster-like picture-based, plate classification is rich, clear hierarchy, operational logic Simple and clear, and there is no repetitive content of the complex, the number of films and television equipped with ultra-genuine Chinese video content. More poly good use, together fun, together to enjoy home, poly good school, poly-purchase and other precise positioning of the plate. Hisense VIDAA Internet TV and China, Fantastic Art, Tencent video industry-leading video platform to reach a strategic cooperation, with 15,000 film resources, 150000 sets of TV drama resources, TV drama average daily update volume of 10 or more. It can be said, VIDAA film and television resources and update the number of resources has been far more than the industry's flagship content of the Internet TV brand.

Just click on the remote control to see the movie icon to enter the player interface, which is not only a story, there are related recommendations, people, tags and other useful features, easy to use. According to the source quality, divided into SD, HD, ultra-clear, blue, 4K categories, the user can choose according to their own network and display device corresponding source. It should be noted that the current part of the latest video is paid to watch, 49 yuan per month, you can watch all the paid content. But even if the user does not buy members, still ensure that 92% of free HD content to watch, and 1080P HD video resources accounted for more than 90%.

Through the test can see Hisense 4K 50mw laser pointer TV in all respects is the top, first of all simple and elegant design, installation and transportation are more convenient, while compared to traditional LCD TV more space-saving; in terms of quality, has been significantly better than ordinary Of the LCD TV, while many LCD TV can not match the advantages, such as just less than 0.5 meters away from the wall space can be projected more than 100-inch display screen, shocking sound unity, with a theater-rated Viewing experience. And in the content, equipped with Hisense VIDAA system is simple and easy to use, with the content and film and television drama resources have gone beyond most other brands, 4K high-quality large want to see.

Speaking of mobile phone wireless charging, everyone's first reaction is likely to do not believe the attitude. Indeed, wireless charging current, just stay in the use of specific wireless charging plate, although mobile phone manufacturers have adopted the fast charging technology in a new generation of wireless charging plate, speed than before to improve a lot, but think of your mobile phone plugged into the charger, or on the wireless charging plate, the difference is not large, so the wireless charging at the present stage, the use of the scene is not particularly attractive. But just a few days ago, a Russian called "energy" rocket Aerospace Corp made a special experiment, they use blue laser pointer for 1.5 kilometers to the mobile phone charging 1 hours, which makes the impression of the mobile phone charging added more imagination. The experiment was completed in two buildings that are 1.5 kilometers apart. In one of the roof mounted laser transmitter, a roof mounted on the plate, and the plate with the conventional mobile phone charging port, charging for mobile phone. Because the laser energy is concentrated and is very strong, so the use of the receiver plate, can be transformed into the laser power transmission to the mobile phone. In this process, although the plate length is only 10cm, but still accurately received laser, accuracy is amazing.

In fact, Microsoft Asia Research Institute in 2015 had done on the use of light charging prototype, then known as AutoCharge. The difference is that when the sun is used to gather burning laser pointer light beams, and then a special charger can lock your phone on the table, and converted into electricity for mobile phone charging. Because the beam is more concentrated, so the whole charging effect, theoretically to achieve the speed of socket charging. Some people would say, this is not and now the wireless charging similar to it, or to put in a specific place. In fact, the core idea of AutoCharge is to allow users to readily put smart phones on the table, through the identification of the charger to determine the location of the device to charge, this process does not require the user to deliberately placed. When charging is complete, charger can be identified by the sensor mobile phone battery has been full and automatically turn off the charging switch beam, this means that you can keep the mobile phone placed at random, charging at the same time, it will automatically charge well closed, fully automated charging operation. However, in order to achieve it, Microsoft researchers said, this technology requires more mature solar technology, but also be restricted in the indoor space. So this prototype experiment is still far away from the actual product, need to be further improved in many ways.

First of all, is to charge the uav. As we all know, short life time has been one of the main shortcomings of the uav. Increase the battery will allow the UAV to increase the weight and weight increase will undoubtedly lead to increases the burden on the UAV, flight time is not effectively enhanced, so in the present, no major breakthrough in the battery industry, so that the UAV flight time increase will become a vicious spiral. And in order to improve their life, scientists have no less effort. Some time ago the Imperial College London in London in the laboratory successfully created a wireless charging device, the charging base through a double circuit board (above etched with a radio transmitter) is also equipped with 13.56MHz inverter, can continue power supply for the circuit board. Let an unmanned aerial vehicle (four axis) in the case of no battery can fly to the height of 12.7cm, it can be said that we have a lot of imagination. But the wireless charging base by power supply mode, the problem is very low, the first is the charging efficiency of the base, it needs very strong power conversion to make UAV Flight High enough. Since the "wireless charging" is not a way, the 100mw laser pointer charge may become another new way to try. Through laser charging, first solve the distance problem is, as previously described, in fact we have been able to 1-2 km distance charging for mobile phone, it means that this process does not need to build large charging base.

this 100mW 532nm Focus Green Beam Light Laser Pointer Pen with 18650 Rechargeable Battery aims at providing you with high-performance light effect. Equipped with high-grade circuit, this laser pointer pen can work regularly. The focus design enables better light effect. So this laser pointer pen is perfect for teaching, guiding and so on.
