Many friends think of home theater, and they think of the words high-end, atmosphere, and grade. The theater equipment must be high-end and high-grade, and the space must be atmospheric. In fact, small-sized home theaters do not have a twist, the small-sized home theater is simp ......
STM32 library function operation brings a lot of convenience to design developers. Developers do not need to fully understand the internal registers and hardware mechanisms of STM32. As long as they have C language foundation, they can complete the development of single-ch ......
LED foundation 1.1 LED working principle As the name implies, a light-emitting diode (LED) is a semiconductor device that emits light of a specific wavelength (color). Like other semiconductor chips, the semiconductor chip of the LED (the actual light-emitting unit of the LED) is also packaged in ......
Yesterday (20), Tongfeng Electronics (600237) announced that the company intends to sign a capital increase holding agreement with Anhui Jiangwei Precision Manufacturing Co., Ltd. (hereinafter referred to as Jiangwei Precision), to Anhui Weiwei Photoelectric Material Co., Ltd., a wholly-owned subsi ......

Nakamura Shuji, one of the three Japanese winners of the Nobel Prize in Physics this year, talked to a reporter in Tokyo on the 3rd about the development of the blue LED patent issue and the old Dongya Nichia Chemical Industry. He hopes to repair the relationship, but not Can do it. Nakamura, a pr ......
Since the winner of the Nobel Prize in physics on October 7th, despite the absence of Chinese people on the list, in the spirit of science without borders, the lighting industry in China has been jubilant, and the media in the industry have become more like explosions. Pots and large inks ......
In the card machine, the card separation gap formed by the card separation axis at the front end of the card in the forward direction of the card and the card separation flap is the key to the separation mechanism. Changes in the gap width and relative position affect the card separation effect ......
1. Brightness and viewing angle The brightness of the display mainly depends on the luminous intensity and LED density of the LED. In recent years, LEDs have emerged with new technologies in substrates, epitaxy, chips, and packaging. In particular, the stability and maturity of indium tin oxide ( ......
The Hall effect rotary position sensor uses a magnetic field instead of a mechanical brush or dial and is dedicated to measuring the angular position of moving parts. This product uses a magnetically biased Hall-effect integrated circuit (IC) to detect the rotational motion of the actuator shaft ......
