June 9th, 2016 is China's traditional festival - Dragon Boat Festival, in this thick festive atmosphere, coincides with the annual Guangya Exhibition. Guangya Exhibition is the most large-scale LED international lighting exhibition in Asia. This year, it is still opening in Guangzhou Pazhou Exhibition Hall.
Shenzhen Mingwei Electronics Co., Ltd. (hereinafter referred to as “Mingwei Electronicsâ€) was established in 2003. For more than ten years, it has been focusing on power supply management, LED lighting and LED display driver chip development. At this year's Guangya Exhibition, Mingwei Electronics also brought a series of LED products to the exhibition.
LED display driver chip series
LED display driver chip is mainly divided into four series, which are LED single-color display driver chip series, LED full-color display driver chip series, LED display logic driver chip series, LED display MOSFET series.
A series of LED single- and dual-color display products, including 8-channel LED constant voltage driver chip. It has strong anti-interference ability and high ESD capability, and its market share is over 60%. Mainly used in LED single and double color display, set top box display panel, small appliance display panel.
LED full color display special series products are constant current source driver chips. The chip has a wide constant current range, high constant current consistency, reasonable response time setting, and meets high refresh rate and low EMI requirements. The market share has reached more than 30%. The series also has more choices in terms of energy saving, refresh rate, channel number, etc., to protect the high-quality display of LED display.
LED display dedicated logic control series, including multi-functional real-world logic devices. It has strong anti-interference ability and high ESD capability, and its market share is over 60%. Mainly used in LED single and double color display, LED full color display, system controller.
LED display dedicated MOSFET series, used as LED scanning screen line power switch tube.
AC-DC power supply series
AC-DC power supply series products adopt 730V hybrid single-chip integrated process technology and Mingwei's original high-voltage self-starting and power supply technology, quasi-resonant control and low standby processing technology, built-in soft start and output overload protection, output Various protection functions such as flow protection, VDD undervoltage protection, and VDD overvoltage protection. It can pass EFT, lightning strike, surge and other reliability tests, and can pass 3C, UL, CE and other certifications to meet the six energy efficiency requirements.
LED lighting drive series
LED lighting driver series, using 730V hybrid single-chip integrated process technology and Mingwei's original constant current control technology, high-voltage self-starting and power supply technology and high power factor control technology and other patented technologies, built-in soft start and output open / short circuit protection, etc. A variety of protection, through EFT, lightning strikes, surges and other reliability tests, can pass 3C, UL, CE and other certifications.
It is understood that after more than ten years of accumulation and precipitation, Mingwei Electronics has nearly 200 patents in IC design high-voltage ESD technology, high-precision constant current technology, high-voltage start-up technology, ultra-low standby power consumption technology, etc. The EMC of power supply, high-voltage EFT, UL, 3C, "Energy Star" and other certifications, and the reliability and stability of power supply have accumulated rich experience and won high praise and trust from customers.
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.
