A Journey Through Display Technologies

-
Welcome to the world of display technology, where screens are more than just visual platforms. They are a blend of science and art, bringing images to life in vibrant colours and sharp contrasts. 
From the sandwich-like structure of LCDs and LEDs to the firefly-like pixels of OLEDs and AMOLEDs, each screen type has its own unique story and characteristics. Whether it’s the affordability of LCD/LED screens, the stunning colour and contrast of OLEDs, the brightness of QLEDs, or the flexibility and speed of AMOLEDs, there’s a display for every need and budget. So, let’s dive in and explore these fascinating technologies together.

  1. LCD (Liquid Crystal Display): Think of LCD as a sandwich. The “bread” is two layers of glass and the “filling” is a layer of special liquid crystals. These crystals can either let light through or block it, which helps create the picture on the screen.

  2. LED (Light Emitting Diode): LED is just a fancy version of LCD. It’s still a sandwich, but instead of using a lamp for light (like in LCD), it uses tiny little lights called LEDs. This makes the picture look better and the screen thinner.

  3. OLED (Organic Light Emitting Diode): OLED screens are like millions of tiny fireflies inside your screen. Each pixel (or “firefly”) emits its own light, so you get really vibrant colours and true blacks because a black pixel is simply a pixel that’s switched off.

  4. QLED (Quantum Dot LED): QLED screens are like LED screens but with an added layer of tiny particles called quantum dots. These quantum dots make the colours on the screen even more vibrant and bright.

  5. AMOLED (Active Matrix OLED): AMOLED is similar to OLED but a bit smarter. Each pixel (or “firefly”) can be controlled individually, so you get even better colours and faster response times. AMOLED can be used in flexible screen technology.


In summary:

  • LCD/LED screens are widely used, affordable, and offer good picture quality with a backlight.
  • OLED screens have excellent colour and contrast with self-lit pixels, making them great for dark scenes.
  • QLED screens are brighter and have more vibrant colours than OLEDs.
  • AMOLED screens combine OLED’s benefits with added flexibility and speed, often used in smartphones.

Each type has its own advantages, and the best choice depends on your needs and budget. OLED is generally considered the best in terms of picture quality, but QLED and LED are more affordable and still offer a great viewing experience.

Bouncing into the Vibes of General Relativity

Tech Rumination by Anirudh Bouncing into the Vibes of General Relativity Imagine you're at a park, and there's a big trampoline there. Now, think of this trampoline as the fabric of space-time, a concept from Einstein's theory of general relativity. Space-time is like a huge blanket that stretches across the universe. When something with mass, like a planet or a star, sits on this blanket, it creates a dip or a curve. This is similar to standing in the middle of a trampoline causing it to sag. So, when a smaller object, like a marble, is rolled across the trampoline, it will move towards the heavier ball at the center, not because there's a mysterious force pulling it, but because the shape of the trampoline is curved. So, in simple terms, according to Einstein’s General Theory of Relativity, gravity is not a for
