Display Technology: How They Work
To understand the pros and cons of CRT and LCD, it’s essential to know how they work.
CRT: The Cathode Ray Tube
A CRT display consists of a large glass tube containing three guns that emit electron beams, which are focused onto a phosphor coating on the inside of the tube. The electron beams excite the phosphor, producing red, green, and blue light, which are then combined to create the final image. The beam is scanned horizontally and vertically across the tube to create the image.
LCD: The Liquid Crystal Display
An LCD display uses a layer of liquid crystals to block or allow light to pass through a matrix of pixels. The liquid crystals are controlled by an electric current, which aligns them to either block or allow light to pass through. A backlight is used to illuminate the liquid crystals, producing the final image.

What is the main difference between CRT and LCD monitors?
CRT (Cathode Ray Tube) monitors use an electron gun to shoot electrons at a phosphorescent coating on the inside of the screen, creating images. On the other hand, LCD (Liquid Crystal Display) monitors use a layer of liquid crystals to block or allow light to pass through, creating images. This fundamental difference in technology affects various aspects of the monitors’ performance, including image quality, power consumption, and durability.
While CRTs are known for their excellent color accuracy and fast response time, they are generally heavier, bulkier, and consume more power than LCDs. LCDs, on the other hand, are thinner, lighter, and more energy-efficient, but they can suffer from limited viewing angles and slower response times.
Which type of monitor is better for gaming?
When it comes to gaming, CRTs are often considered the better choice due to their fast response time and low input lag. This means that CRTs can display fast-paced games with minimal blurring or ghosting, providing a more immersive gaming experience. Additionally, CRTs can handle high refresh rates and display fast motion more smoothly, making them ideal for first-person shooters and other fast-paced games.
However, LCDs have made significant improvements in recent years, and some high-end gaming LCDs can rival CRTs in terms of response time and input lag. These LCDs often use advanced technologies like G-Sync or FreeSync to reduce screen tearing and provide a smoother gaming experience. Ultimately, the choice between CRT and LCD for gaming depends on personal preference and specific gaming needs.
Do CRTs produce better color accuracy than LCDs?
CRTs are generally considered to have better color accuracy than LCDs due to their ability to produce a wider range of colors and more subtle color gradations. This is because CRTs use a combination of red, green, and blue phosphors to create colors, which can result in a more nuanced and lifelike color representation. Additionally, CRTs tend to have better color consistency across different viewing angles, which means that colors remain accurate even when viewed from the side.
However, some high-end LCDs have improved significantly in terms of color accuracy, and some can even rival CRTs in this regard. These LCDs often use advanced technologies like IPS or OLED panels, which can produce a wider color gamut and more accurate color representation.
