FULLLED TV re-engineering legend

Step into the TV sales area of ​​the appliance store, you will find that many prominently placed LCD LCD TVs are no longer purple, and replaced by the market new LED LCD TV. In 2010, LED TVs were fierce, and they have already shown a complete replacement for CCFL-backlit LCD TVs. The LED TV era is coming.

In the face of a large number of new LED TV models, how should consumers choose? Industry insiders told reporters that in addition to continuing to focus on panel, response time and other technical indicators, there is an important way to understand what kind of LED backlight technology is used in TV sets.

The new direct-type FULLLED backlight technology introduced by LG Electronics this year solves the above two shortcomings. On the one hand, it achieves the uniform distribution of LED backlights and accurate localized light control, resulting in beautiful image quality; on the other hand, Brought to the consumer with a thin body and ultra-narrow bezel. In the slim design of the fuselage, the straight down type is larger, the side entry type is second, and the FULLLED can make the thickness of the TV set to the extreme. In terms of image quality, the side-entry, direct-down and FULLLED TVs present a progressive upward relationship; in terms of cost, the high-end FULLLED TV is relatively high, but for high-end consumers. It is also completely affordable.

The Co-Al Co-doped Barium Titanate Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company through repeated experiments. By Researching the influence of Co-Al Co-doping on the structure and properties of Barium Titanate-based piezoelectric ceramics, the formulation and preparation technology of Barium Titanate-based piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N), dielectric loss tgδ≤0.5% and mechanical coupling coefficient  Kp≥0.34.

Barium titanate lead-free piezoelectric ceramics are important basic materials for the development of modern science and technology, which was widely used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscope and so on.

Application:  military, ocean, fishery, scientific research, mine detection, daily life and other fields.
