Why is the TV as the quality of audio-visual equipment?

TV as an audio-visual equipment, although in recent years, various color TV manufacturers have made great efforts in intelligent functions, such as voice control, multi-screen interaction, installation and uninstallation applications, etc., but it can not help but create a sense of uniformity, although better, but Homogenization is very serious. The author believes that TV as an audio-visual equipment, picture quality is the key, after all, viewing is the first responsibility of the TV.
In the current color TV market, there are actually many outstanding image quality technologies. Display technologies such as OLEDs and quantum dots must have a little understanding of the consumers in the TV industry. In the ten years of liquid crystal dominance, these new panel technologies have become A breakthrough.
Among them, LG's OLED panel is known for its excellent color, and can be fabricated on substrates of different materials, and can even be made into a flexible display that can be bent. In the early part of this year, Sony also launched its first OLED TV, which makes people wonder about the possibility of OLED in the future.
TCL and Samsung's main quantum dot technology use liquid crystal as a breakthrough to use the most pure quantum dot source as the backlight. The revolutionary realization of full color gamut display, the most authentic color reduction, is more advantageous than OLED TV. As an emerging display technology, quantum dots have become the core technology of choice for more and more international leading TV manufacturers. Quantum dot TVs have an advanced experience in terms of color gamut, color, longevity and price, as evidenced by recent market sales data.
As a leading brand in the field of quantum dot technology, TCL is actively promoting the application of quantum dot technology and the promotion of quantum dot TV. As the first company in China to launch quantum dot TV, TCL launched QLED TV primary color quantum dot TV X2/X3 in the spring, with three advantages of high color gamut, pure color and long color.
In fact, not only OLEDs and quantum dots, but also ULEDs, laser TVs, etc. proposed by domestic manufacturers Hisense, all have strong image quality. Taking Hisense Laser TV as an example, Zhongyikang data shows that Hisense Laser TV increased 408.2% year-on-year in April this year, and its market share and market share in the 80-inch and 85-inch sizes are far ahead of other brands. Among them, Hisense's 80-inch laser TV has a 45.3% share, and Hisense's 80-inch laser TV has a 62.1% share.
In addition, Skyworth's solid color technology, unlike quantum dot technology, is a new generation of color enhancement technology. Simply put, it adds a layer of photo-nano material between the wide-gamut backlight and the liquid crystal module, that is, micro-particles with a diameter of about 1 nm, which specifically absorbs the stray light from the backlight, thereby enhancing the red, green and blue primary colors. The purity solves the problem that the red, green and blue primary colors emitted by the LCD TV backlight are not pure, and thus can display the picture color more accurately and more realistically.
The solid color technology enhances the color purity displayed on the screen by absorbing the remaining light waves, resulting in stunning image quality. For example, green on a regular TV can be mixed with other color wavelengths (such as yellow or blue), causing the color to fade and appear a yellow or cyan hue. Solid color technology minimizes fading, image instability, and other color discoloration problems, and reduces halo on the screen, ensuring high quality images even when the screen is surrounded by intense ambient light.
At the same time, the TV with solid color technology allows viewers to see consistent colors on the front and side of the TV, with almost no chromatic aberration, making it an ideal large-size, high-definition TV. The breakthrough achieved by solid color technology is another important milestone in the history of color display technology.
It can be said that the birth of OLED, quantum dots and solid color technology has not only become an irreversible trend of mainstream TV display technology in the future, but also fully promoted the accelerated upgrade of TV display technology. Therefore, the author believes that the future TV display will be more and more outstanding, consumers will also appreciate a clearer TV picture.

Piezoelectric Material

Yuhai piezo materials include : hard piezo material, soft piezo material and lead free piezo material

Soft piezo material exhibits: larger piezoelectric constants, higher permittivity, larger dielectric constants, higher dielectric losses, larger electromechanical coupling factors, low mechanical quality factors, a lower coercive field, poor linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.

Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.


Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
