When it comes to display quality, there are distinct differences between CRT, LCD, and plasma screens. Each technology has its own strengths and weaknesses in terms of visual performance. In this article we will look at the differences between Plasma CRT and LCD displays.

CRT Displays

CRT screens, also known as cathode ray tube screens, were once the dominant display technology. They were known for their deep blacks and high contrast ratios. However, CRT screens tend to have lower resolution and colour accuracy compared to modern display technologies.

CRT utilize a cathode-ray tube to produce images. These tubes shoot electrons onto a phosphorescent screen, creating the vibrant colors we associate with older TVs and monitors.


  1. Contrast Ratio: CRTs are renowned for their exceptional contrast ratios, providing deep blacks and vivid colors.
  2. Viewing Angles: Superior viewing angles compared to early LCDs.


  1. Bulkiness: CRT displays tend to be bulky and heavy, occupying more space than modern alternatives.
  2. Energy Consumption: They consume more energy than LCD and Plasma displays.

LCD Displays

LCD screens, or liquid crystal displays, have become the standard in most electronic devices today. They offer higher resolutions and improved color accuracy compared to CRT screens.The display work on the principle of liquid crystals manipulated by an electric current. Each pixel is controlled individually, allowing for precise image reproduction. LCDs also have better energy efficiency and thinner profiles. However, they may struggle with achieving deep blacks and can suffer from limited viewing angles.


  1. Slim Design: LCDs are slim and lightweight, making them ideal for modern aesthetics.
  2. Energy Efficiency: Lower energy consumption compared to CRTs.


  1. Limited Viewing Angles: Viewing angles may be restricted, affecting the overall viewing experience.
  2. Black Levels: Historically, LCDs struggled with achieving deep blacks.

Plasma Displays

Plasma screens are another type of display technology that was popular for a period of time. Plasma displays use tiny gas cells sandwiched between glass panels. When an electrical charge is applied, the cells emit ultraviolet light, stimulating phosphors to produce visible light. Plasma displays excel in areas such as color reproduction and contrast ratios. They offer deeper blacks than LCDs and wider viewing angles. However, plasma screens tend to be more power-hungry than other technologies and are less commonly found in modern devices.


  1. Wide Viewing Angles: Plasma displays excel in providing wide viewing angles, ensuring a consistent image from various positions.
  2. High Refresh Rates: Well-suited for fast-moving content like sports or action-packed movies.


  1. Susceptible to Burn-In: Plasma screens can experience burn-in issues, where static images may leave a lasting impression.
  2. Energy Consumption: Plasma displays generally consume more energy than LCDs.

In the CRT vs. LCD vs. Plasma showdown, the best choice depends on your specific needs. If your wish is to experience past technology and vibrant colours with a compromise on space, CRT might be your choice. For sleek designs and energy efficiency, LCDs are the way forward. Meanwhile, plasma displays offer dynamic visuals with wide viewing angles, but may not be suitable for prolonged static content.

In summary, while CRT screens were known for their deep blacks but lower resolution and color accuracy compared to LCDs or plasmas; LCDs offer higher resolutions but may struggle with achieving deep blacks; plasma displays excel in areas such as color reproduction but consume more power. The choice of display technology ultimately depends on individual preferences and specific use cases.

Consider your priorities, whether it’s space, energy efficiency, or specific visual requirements, to make an informed decision in the world of display technologies.

F. A. Q

Which display technology is best for gaming?

For gaming enthusiasts, LCD and Plasma displays are generally preferable. LCDs provide low input lag, while Plasma displays boast high refresh rates, making them suitable for fast-paced gaming.

Are CRT displays still worth considering in the modern era?

While CRT displays have nostalgic value, their bulkiness and higher energy consumption make them less practical for today’s needs. Modern alternatives like LCD and Plasma offer sleek designs and better energy efficiency.

Do LCDs still have issues with limited viewing angles?

Although early LCDs struggled with viewing angles, advancements in technology have significantly improved this aspect. However, for applications requiring extremely wide viewing angles, Plasma displays may still have an edge.

Can Plasma displays suffer from burn-in issues?

Yes, Plasma displays are susceptible to burn-in, where static images can leave a lasting impression. This makes them less suitable for applications involving prolonged static content, such as continuous display of logos or tickers.

Which display type is more environmentally friendly?

In terms of energy efficiency, LCDs are generally more environmentally friendly due to their lower power consumption. However, it’s essential to consider the entire lifecycle of the product, including manufacturing and disposal.

Are CRT displays completely obsolete?

While CRT displays are no longer mainstream, they may still find niche applications or appeal to individuals seeking a vintage aesthetic. However, the practicality of CRTs is limited compared to the sleeker and more energy-efficient options available today
