According to the "IDC 2020 Fourth Quarter China Projector Market Tracking Report", China's home projector sales in 2020 will be 3 million units, a year-on-year increase of 7.5%. IDC predicts that the five-year compound growth rate of China's projector market will still exceed 15% by 2025. The domestic brands XGIMI, JMGO, Xiaomi Group, Dangbei and Hisense ranked in the top five, breaking the monopoly of foreign brands in the Chinese projector market for more than ten years, and created a number of new technologies in the field of intelligent projection.

Recently, Tonghui Electronics has customized a set of automatic power supply test system TH300 for a domestic head projector brand. This power supply test system realizes 4-channel synchronous test, which can test 12 types of parameters such as low-voltage no-load start and low-voltage full-load ripple ( dozens of sub-projects), and generate customized data analysis reports. The power supply, load and other instruments in the system are independently developed and produced by Tonghui, adhering to Tonghui's more than 20 years of technical accumulation and craftsmanship, with quality as the guarantee, to provide users with a smooth testing experience.
