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.

4K is not yet 8K has risen 2018 television market brewing new changes
According to market research firm IHS Markit, the adoption of 4K organic light-emitting diode (OLED) TVs has been steadily growing in the premium TV segment, priced at over $1,000. This upward trend is largely driven by major players like Sony and LG Display. By 2019, IHS Markit predicts that 4K OLED TV shipments could account for as much as 60% of the high-end TV market.
However, the agency also forecasts that 8K LCD TVs will hit the market in 2018, with 65-inch and 75-inch models leading the charge. These new models are expected to carry a price tag that’s about 35% higher than their 4K counterparts.
Despite this, as production capacities for larger LCD panels expand, particularly those above 65 inches, the cost difference between 4K and 8K TVs is likely to narrow. This shift could temper the growth rate of 4K OLED TV sales in the coming years.
For those interested in smart TVs or TV boxes, there are numerous resources available online. China’s Sofa Butler (http://) is a popular destination for news, reviews, and discussions on smart TVs and TV boxes. Whether you're looking for advice on smart TV software, hardware recommendations, or just want to engage with fellow enthusiasts, this platform offers a wealth of information to help you stay informed and connected.
In summary, while 4K OLED TVs continue to dominate the premium TV space, the emergence of 8K technology presents an interesting challenge. As production scales up and prices adjust, the dynamics of the TV market will undoubtedly evolve, offering consumers more choices and potentially reshaping consumer preferences.
