Wide color gamut PK solid color hard-press quantum dot liquid crystal

With the improvement of people’s living standards, the consumption upgrade boom has swept the entire color TV industry. Therefore, consumers have also put forward higher requirements for the color TV industry, and the picture quality is the main theme of the technology upgrading of the color TV industry. In today's "picture quality is king", the wide color gamut has become a very popular technical standard in the television field. Therefore, many TV manufacturers have introduced TV products adopting the wide color gamut technology to meet the needs of consumers. The most representative products in LCD TV products are solid color hard screen products and quantum dot liquid crystal products. So from a consumer perspective, which TV is better?

This topic also triggered great interest from imaging science expert Professor Xu Haisong of Zhejiang University. In order to conduct more in-depth research on the wide-gamut television, Professor Xu Haisong chose quantum dot LCD TV and solid color hard-screen TV Skyworth Q8. As a test sample, the color gamut television has a quantitative experiment under the premise that the sample screen size and resolution are the same. Test results show that solid-color hard-screen technology is not limited by the viewing angle, and is a true wide-gamut television technology; and solid-color hard screens use nano-materials to filter stray light, which is more realistic than quantum dot liquid crystals.

Solid color hard screen is not limited by the angle of view, is a real wide color television

Nowadays, under the wave of “returning to the family”, television has returned to the entertainment center and has become an important output window for emotional exchanges. Therefore, a wide-gamut TV that is truly not subject to viewing angles is the heart of consumers.

Professor Xu Haisong selected two broad color gamut products on the market - solid color hard screen Skyworth Q8 products and quantum dot liquid crystal products, and measured its wide color gamut maintenance rate with changeable viewing angles.

As we all know, the wide color gamut is a selling point that Quantum dot LCD TVs are proud of, but the results of the experiment are eye-popping. The test results show that with the increase of the viewing angle, the color gamut area of ​​the quantum dot LCD TV rapidly shrinks, and its white point also shifts greatly; while the color gamut area of ​​the solid color hard-screen TV Skyworth Q8 hardly follows the observation angle. Increasing and decreasing, the white point changes little. Taking the normal viewing angle of 40° as an example (as opposed to the frontal view), the solid color hard-screen TV Skyworth Q8 can still maintain 97.5% of the color gamut area relative to the frontal viewing, while the quantum dot LCD TV can only reach 73% color. The area of ​​the domain actually lost 27% of the color gamut area, and the quality of the image can be imagined. Even at an observation angle of 80°, a solid-color hard-screen TV still achieves a color gamut area of ​​96.3%, which is unmatched by quantum dot LCD TVs. In other words, when viewed from the side at 40° and 80°, the color gamut area of ​​a solid-color hard-screen TV has almost no loss, and almost the same effect as when viewed from the front; and the quantum dot LCD TV has a very large color deviation. From this point of view, a solid-color hard-screen TV can be regarded as a true wide-gamut TV that can watch the wide color gamut from any angle.

Nano-material filter stray light, solid color hard screen is more realistic than quantum dot liquid crystal

Over the years, color improvement technology has always been an important direction for the development of LCD TVs. Previously, quantum dot technology gained “short-term approval” with its “liquid crystal display improvement” solution, but it was unable to maintain a wide color gamut at the viewing angle, and it also made quantum dot LCD TVs vulnerable to criticism. Until the emergence of solid-color hard-screen technology, it broke the liquidity field with few substantive breakthroughs.

Solid color hard screen technology and quantum dot liquid crystal technology are both wide color gamut technologies. Different from quantum dots' emphasis on the enhancement of color brightness, solid color hard screen technology focuses on the improvement of the purity of the screen colors, and is a kind of “purification” technology for screen colors. The hard-colored solid-screen panel incorporates nano-materials, which specifically absorb the stray light emitted by the backlight to achieve the purpose of enhancing the purity of the three primary colors of red, green, and blue, so that more abundant colors can be more accurately and more realistically presented.

As the latest color improvement solution, solid-color hard-screen technology has been called a milestone breakthrough in the history of color, and some people even praised solid-color hard-screen technology with the term “stand on the shoulders of giants”. China Electronic Chamber of Commerce, a professional and authoritative organization, issued an authentication certificate for excellent solid-color hard-screen technology, arguing that "hard-color hard-screen technology is an excellent technology for maintaining the color gamut and color gamut, and its wide color gamut technology does not contain harmful substances. Pure-color hard screen Absorb the backlit stray light to make the color more pure.” In addition, Terui Te, deputy general manager Wu Hao also said that solid-color hard screen technology is expected to surpass the quantum dot technology to achieve a new leap in the field of display technology in the future, new horizons, new controversy .


TV screen structure using solid color hard screen technology

This year, the struggle between quantum dot liquid crystal technology and solid-color hard-screen technology, with LCD color improvement as the main battlefield, will surely be fierce. The solid-color hard-screen technology with excellent color gamut and color gamut retention rate is clearly superior, and overcomes the drawback that quantum dot LCD TVs will drastically decline if they exceed a certain viewing angle, which is more suitable for ordinary homes and offices. Watch the TV in the environment. In addition, in subjective tests conducted by Prof. Xu Haisong, the color retention of solid-color hard-screen TVs also beats quantum dot LCD TVs, and the peak brightness, darkness, contrast, vividness, authenticity, and detail reduction of solid-color hard-screen TVs are also restored. The seven core attributes, such as overall preference, are higher than quantum dot LCD TVs. This also shows that for consumers, solid-color hard-screen TVs are wide-gamut TVs that are better viewed and more popular.
