On a sunny weekend, Xiao Lin bought several plastic storage boxes, planning to organize her wooden bookshelf properly. “I am—” A cheerful response suddenly appeared. Clearly, no one called, yet … Read more
Many students who are new to microcontrollers often have a question: With chip technology being so advanced now, and our boards operating at voltages of 5V and 3.3V, which are low-voltage DC circuits, do we still need to consider electrostatic issues like the old engineers did, with such caution? 1. What is Electrostatics? Electrostatics can … Read more
The chassis is made of metal, and there is a screw hole in the middle, which connects to the ground. Here, a 1M ohm resistor is connected in parallel with a 0.1uF capacitor to the ground of the circuit board. What are the benefits of this setup? If the chassis ground is unstable or has … Read more

TFT-LCD Display Module ESD Testing Diagram In the fields of electronics and optoelectronic displays, there exists a frequently overlooked but potentially serious “invisible killer”—static electricity (ESD). When static electricity is discharged onto a TFT-LCD display module, it can cause functional issues such as black screens, white screens, distorted screens, horizontal lines, vertical lines, flickering, and … Read more
