Researchers from Uppsala University and the University of Gothenburg have proposed a new type of anti-glare screen that can achieve extremely high pixel density. This technology is expected to overcome one of the main shortcomings of electronic ink technology, thereby promoting the widespread application of low-power, high-resolution displays. It is reported that this manufacturing process, … Read more
In today’s era of ubiquitous smart devices, screens serve as the bridge connecting the digital world with the physical one. From simple status indicators to complex graphical human-machine interfaces, their operation relies on the precise collaboration of various liquid crystal technologies. Understanding the core differences between different types of LCD screens is a crucial step … Read more
Ghosting is generally divided into two types: short-term ghosting (temporary ghosting) and long-term ghosting (permanent ghosting, also known as “burn-in”). They have different causes and properties, and understanding their differences helps us respond more scientifically. Short-term ghosting: a reversible ion accumulation phenomenon, is a normal physical occurrence that can happen on all LCD screens and … Read more
