Have you ever encountered issues like color cast or screen flicking with your monitor? This issue could be caused by a poorly-made monitor, but there are also other reasons for this. So, what are they?
This is the Main Reason For These Issues
In terms of high-frequency and high-speed transmission, the quality of motherboards in displays mainly depends on impedance. For example, imagine you’re running at a certain speed on asphalt, sand, and gravel. It would be difficult to run at the same speed for all of the different types of roads. It’s the same logic for motherboards. When the transmission parameters and conditions are different, it’s hard to transmit high-speed signals. Unstable signals on a motherboard will affect the quality of the entire product.
The Various Effects of Impedance on Motherboards
What happens when the impedance isn’t controlled well? Minor issues could include decreased resolution, color shifting, screen flickering, or flashing. Major issues could include display failure, no signal detection, and more. Below are some factors that could lead to poor impedance.
Poor design
Issues such as improper corner routing, incorrect connector pad size, not considering Via, and others will cause uneven surfaces.
Board manufacturers
The quality of the equipment and their employees can have an impact on the product they are producing.
Product verification
Brands and manufacturers who specialize in product design but don’t fully understand testing and verification could affect their products. Lack of testing equipment is also a main obstacle for brands and manufacturers.
