Distinguished.
In May 2008, at the Australian Open, there was Hisense. The Chinese players finally had a particularly stable home feeling. When you watched the F1 game, you saw the Red Bull Racing team has Hisense; when you watch the US NASCAR racing , go to Germany to see Shalt 04, you can see Hisense; in South Africa, go to North American TV stores, you can still see Hisense TV. For us Chinese people, there is such a world-class enterprise, of course, will be very excited. Last year, Hisense also entered the top European stadium in the name of the top sponsor of the European Cup. Chinese companies began to replace Japanese and South Korean companies as the vanguard of world competitions.
Internationalization is one of Hisense's strategies. At present, sales volume of Hisense TV has reached the third position in the world. But obviously Hisense is not satisfied with this. Although Hisense had more than US$3.2 billion in overseas revenue in 2015, there is a large gap between overseas business and overseas countries. To this end, following the European Cup sponsorship in 2016, on April 6, 2017, Hisense officially announced the official sponsorship of the 2018 FIFA World Cup, which means that Hisense’s “brand internationalization strategy” can be extended again, and the World Cup official will also Relying on Hisense, the company developed special technologies such as live show display.

Intelligent Sports Frame Measurement was born as a dedicated World Cup TV product for football fans around the world. It is particularly valued for the quality of the picture, the sound quality, and especially the performance of high-speed sports games such as football matches. Over the years, Hisense has continuously increased its investment in R&D, improved its R&D system, and devoted itself to technological innovation. It has continued to make breakthroughs in its core technologies and established its core competitive advantages. The Hisense series can be said to incorporate a number of core image quality technologies in order to meet the user's demand for core image quality.
We know that the colorful colors on the green field are very much a test of the television picture layering, detail processing and color performance. If not dealt with properly, it will greatly reduce the fans' viewing experience. Hisense TV continues to increase its UHD video quality technology, and has UIntel's proprietary intelligent ULED's fine dynamic backlight control. The details of light and darkness can be accurately controlled. Each backlight can achieve 4096-level fine dimming. With HDR quality technology, it can be further improved. Really restore the screen level, detail and color. Quantum dot four-dimensional color reproduction technology has been adopted to expand the color range, and quantum dot luminescent materials can ensure that color does not fade for a long time, and the color lasting stability can reach tens of thousands of hours.
The perception of color by the naked eye is inseparable from the light. Ambient light is an important factor affecting the picture quality of TV. The color performance reflected in the screen under different brightness is also different. For this reason, Hisense TV adds intelligent light technology, which can be adjusted according to the brightness of the ambient light, and it can also intelligently match the color of the image under the corresponding brightness. In other words, no matter how the ambient light and shade change, Hisense TV screen color will automatically adjust to achieve the best picture color.
When viewing a dynamic picture, the stability of the picture is affected by the signal source, transmission process, and display device. If the number of frames or the number of frames that can not be displayed stably is not available, the originally coherent screen will be shaken or blurred, and the details of the screen will be lost, which will seriously affect the viewing experience.
For the phenomena of smearing and jitter in high-speed motion pictures, Hisense TV specifically uses the Motion Flow intelligent motion frame measurement technology to enhance the intelligent frame measurement of motion pictures, which can clearly and smoothly restore the physical motion trajectory and is more suitable for viewing. Large-scale sports events like the World Cup.

Objective Instrument Test: NTSC color gamut up to 102.03%
For a more intuitive and fair demonstration, the author decided to skip other steps and directly perform objective instrument testing on the TV. The instrument used in this test was a BM-7A luminance colorimeter produced by Topcon to measure the color coordinates of Hisense ULED 65-inch TVs in different colors. According to the corresponding values, the contrast, color gamut, color temperature, color saturation, and corresponding color characteristics maps are calculated. Before conducting this test, we first allowed the machine to work normally for one hour and restore it to the factory mode. The entire test environment was performed in the darkroom.
Super-quality TV brings a whole new image quality system solution. Hisense ULED super-quality technology has been developed to ULED 4.0. At present, this technology is quite mature. ULED4.0 increases the brightness to 1000nit, and the dynamic range reaches HDR1000. Quantum dot four-dimensional color reproduction technology brings color expression to the four-dimensional era. The color gamut is raised to 140% BT.709, and the color range has been greatly expanded. The multi-dynamic backlight partition control technology can realize backlight exclusive control in any area, achieve high contrast and restore a better picture level.
After objective instrument testing, we calculated that the NTSC color gamut of the Hisense TV series 65-inch TV has exceeded 100%, reaching a staggering 102.03% in the industry. The color gamut coverage is far beyond the industry's standard color gamut coverage of 72% (NTSC1931) From the objective data, it perfectly embodies the ultimate advantage of the wide color gamut of this TV quantum dot.
From the actual display effect, the three red, green and blue colors used in the test are true and natural, and they are not overly saturated. At the same time the static contrast reaches 40896:1. So relying on such excellent objective values, this TV can achieve high-end image quality requirements in actual playback? Below we look through several sets of local 4K images and UHD videos.

Local 4K image test: The flagship image quality level in the local 4K image test, the author after shooting a large number of materials, according to the type of intentionally selected the following four representative pictures, from the color performance, dark details, light and dark contrast and more From the perspective of the analysis, the entire shooting process is in a darkroom environment, to see if this Hisense TV can match the objective data of the high color gamut.
In the first picture, the color is comfortable, although the color gamut is 102.03%, but it is not over-saturated while fully displaying the color. The second picture is to test the details of the dark parts of the TV. The entire waistline of the rear end of the screen is fully displayed. At the same time, the layering and three-dimensionality of the vehicle are obvious. The black death phenomenon that the author fears does not occur. The last two pictures test the brightness and darkness of the TV. The details of the shadows on the screen are not lost due to darkness, and the light and shadow effects of the highlights are put in place to fully reflect the sense of depth and depth of field.

UHD Video Test: Decoding Perfect Optical Control The perfect quantum dot is a solution nanocrystal, with unique electro-optic characteristics. It is stimulated by electricity or light and emits a very pure high-quality single color of various colors depending on the diameter of the quantum dot. Color light. At the end of 2014, Hisense first introduced TVs equipped with quantum dot technology in China, and QDTV became a representative of emerging display technologies. This Hisense TV combines ULED fine dynamic backlight control with the color performance of quantum dots, resulting in 1+1 greater than two.
Although the current quantum dot technology is in the light-to-light phase, it does not escape the shackles of the backlight, which means that light leakage is still inevitable. However, after the actual testing of local UHD video, the black field performance can even be compared with OLED TVs, but the lights are not dimmed, but brighter. The second paragraph of video color control in place, high accuracy, looks real and natural. The details of the face of the last video character can be displayed almost perfectly. At the same time, the light and shadow control is excellent.
Excellent audio and video integration with front-facing audio effects In fact, many people often ignore the sound quality when they experience TV products. Actually, as a high-end TV, the sound effects largely determine the subjective experience of the user experience. Hisense TV adopts a 3D style front stereo on the physical form of the TV. During the experience process, the sound is transparent and unobstructed, and the surround feeling is more intense. It is worth mentioning that WAVES audio supports multiple modes, such as super bass, vocal enhancement, clear treble, and stereo surround mode. When experience, it can be adjusted according to the environment and playback content, so that this TV does not need to connect other audio equipment. Both can have a stunning sound field experience.

HDR video test: HDR1000 is comparable to ambient light At present, quantum dots, OLEDs, and HDR have become one of the hot spots in the TV market. HDR is the only hot area in which all brands participate. With the development of HDR technology, HDR-free TVs are not available. It may not be possible to analyze or watch HDR sources in the future. TVs equipped with HDR technology can significantly enhance the screen display contrast and color range. The bright part of the screen will be clearer, the dark part will have more depth, and the layers will look more distinct. The increase in color accuracy will also make the color look more pure. And bright.
ULED peak brightness gives more levels of color, smart light technology allows color to feel time, space changes, showing realistic details and light effects. With HDR technology, greater contrast can be achieved because the brightness can be directly driven by the brightness and contrast performance under the backlight. Raising the contrast can make the bright part of the picture brighter, and the dark details can be clearly structured.
In the actual HDR video test, video screenshots show that the shadows are more profound and the colors are real and vivid. The advantages of high brightness make the performance of HDR video smooth and painless. The test duration is dazzling and the ambient light is comparable to the scene. In addition, even on tiny details such as the hair on a person's arm, they can be easily identified without careful observation.

Directional Antenna

Directional antennas are a vital component in wireless communication systems, renowned for their ability to transmit and receive signals with a high degree of directionality. These antennas are designed to focus their radiation pattern in a specific direction, enhancing the signal strength in that direction while minimizing interference and noise in other directions. Directional antennas come in various shapes, sizes, and configurations, each tailored to meet specific communication requirements. In this article, we will delve into the classification and key features of directional antennas.

Classification of Directional Antennas

1. Beamwidth and Gain
   • Narrow Beamwidth Antennas: These antennas have a narrow radiation pattern, resulting in a high gain in a specific direction. They are ideal for long-distance communication and applications requiring high directionality, such as satellite communication, point-to-point microwave links, and radar systems.
   • Medium Beamwidth Antennas: Offering a balance between gain and coverage, medium beamwidth antennas are commonly used in cellular networks, Wi-Fi access points, and other applications where a balance of range and coverage area is crucial.
   • Wide Beamwidth Antennas: With a wider radiation pattern, these antennas provide broader coverage but with lower gain. They are suitable for applications where wide-area coverage is essential, such as TV broadcasting, emergency communication systems, and some types of IoT networks.
2. Polarization
   • Linearly Polarized Antennas: These antennas radiate energy with a linear polarization, either horizontally or vertically. They are commonly used in terrestrial communication systems due to their compatibility with most transmitting and receiving equipment.
   • Circularly Polarized Antennas: Circular polarization occurs when the electric field vector rotates in a circular or elliptical path as the wave propagates. Circularly polarized antennas are ideal for satellite communication and applications involving moving receivers, as they maintain signal integrity even when the antenna's orientation changes.
3. Array Configuration
   • Yagi-Uda Antennas: A popular type of directional antenna, Yagi-Uda antennas consist of a driven element and multiple parasitic elements. They offer high gain and directionality, making them suitable for long-distance communication and television broadcasting.
   • Parabolic Dish Antennas: As discussed earlier, parabolic dish antennas use a parabolic reflector to focus the radio waves into a narrow beam. They are commonly used in satellite communication and radar systems due to their high gain and excellent directivity.
   • Panel Antennas: Sector panel antennas are flat, directional antennas designed to cover a specific sector of a circle. They are widely used in cellular networks, where multiple panel antennas are mounted on towers to provide coverage in various directions.
4. Frequency Range
   • Directional antennas are available in a wide range of frequency bands, from low-frequency (LF) and medium-frequency (MF) bands used for broadcasting and marine communication to high-frequency (HF), very high-frequency (VHF), ultra-high-frequency (UHF), and microwave bands used in cellular networks, Wi-Fi, and satellite communication.
