Connecting a Resistor and Capacitor Between PCB GND and Chassis GND for Better Performance

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

Key Materials for ESD Control in TFT-LCD Display Modules: A Practical Guide (Part 1)

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
