In this blog post, we’ll look at what LIBS is and why Curiosity uses it to analyse Martian soil.   What is LIBS? LIBS stands for Laser-Induced Breakdown Spectroscopy. Put simply, it is a method of identifying the constituent elements by firing a strong laser pulse at a sample to instantly turn it into a plasma state, and then analysing the spectrum of light emitted as the plasma cools. The...

In this blog post, we’ll focus on temperature and thermal management systems—particularly the role of thermal interface material (TIM)—which significantly impact the lifespan of LEDs.   LEDs and Heat: Why Temperature Matters An LED (Light Emitting Diode) is a device that emits light when an electric current flows through a compound semiconductor junction, causing electrons and holes to...

In this blog post, I will provide an easy-to-understand overview of the basic principles and structures of LCD and OLED, as well as the pros and cons of each technology.   Basic Concepts of Displays Displays are core components that serve as the “face” of most electronic devices, such as TVs, computers, and smartphones. As electronic devices have become more sophisticated, the demand for...

In this blog post, I will summarize the current state of K League broadcasts and related programs, as well as the reasons why they need to be improved.   Current Situation: Broadcasts Focus on European Soccer, K League Takes a Back Seat Currently, soccer-related programming in Korea is overly biased toward European leagues, while K League-related broadcasts are relatively scarce.
