In the early days buying television was easy as there was no variation in the technology. People were just concerned about the brand and the screen size of the television.
But over time, the technology of television has evolved greatly. Each television technology has a specific display method. HDTV and plasma technology are one of these technologies.
Key Takeaways
- HDTV is a high-definition television standard, while plasma refers to a specific type of flat-panel display technology.
- Plasma TVs offer superior color accuracy, contrast ratios, and motion handling compared to many other display types, including some HDTVs.
- Plasma technology is no longer in production, whereas HDTV standards continue to evolve with advancements in display technology.
HDTV vs Plasma
HDTV stands for High Definition Television and is a digital broadcasting standard that provides top quality picture and audio compared to a normal television. Plasma is a television display technology in which each pixel on the television screen is illuminated by a small amount of charged plasma.

HDTV or High-Definition Television is a digital broadcasting standard that provides superior quality of audio and picture compared to that of standard televisions.
One of the most significant features of HDTVs is its wide view screen which is measured 16:9. Research shows, wide-view TV screens enhance the experience of the viewers.
Plasma refers to a television display technology where each pixel on the television screen is illuminated by a small amount of charged gas or plasma.
Two thin glasses encased the plasma on the TV screen. Generally, plasma screens provide better wider viewing and dark-room viewing experience compared to LCD.

What is HDTV?
HDTV refers to High Definition of Television which is a new means of TV broadcasting. HDTV broadcasts video digitally and of a higher resolution of 720 P or 1080 I (P stands for pixel and I stands for interlaced scanning).
It provides superior quality of audio and picture compared to that of standard televisions. Generally, digital transmission is used in HDTV rather than analog signal transmission.
However, Japan introduced the first analog HDTV program in 1989.
One of the most significant features of HDTVs is its wide view screen which is measured 16:9. Research shows, wide-view TV screens enhance the experience of the viewers.
The pixel number of HDTV ranges from 2 million to 1 million. It also provides a high-quality audio signal compared to that of standard-definition television.
For watching HDTV an HDTV-compatible television is needed. HDTV comes in both 4:3 and 16:9 formats (for compatibility and backward).
Some of the High Definition Televisions include HDTV tuners to receive over-the-air broadcasts. The enhanced resolution is one of the advantages of HDTV. The image display technology of HDTV is progressive instead of interlaced.
It means instead of alternating between the partial display of the picture, the whole picture is continuously shown on HDTV.
What is Plasma?
Plasma refers to the television display technology that uses a small amount of charged gas or plasma in between two glasses of the television screen.
Plasma displays usually offer a wider viewing and better dark-room viewing experience compared to that of LCD TVs.
The plasma technology was invented in 1964 at the University of Illinois by H. Gene Slottow, Donald Bitzer, and a student named Robert Willson.
Plasma TVs cannot be made in small sizes. The smallest plasma television is 30 inches. The largest plasma television has a 150 inches screen.
Plasma TVs are vulnerable to burn-in which is an issue caused by a static image appearing on the television screen like a channel number or a logo.
When it remains on the television screen for a long time, there is a chance of burning the image into the television screen.
One of the main advantages of Plasma TVs is their wide viewing angles. The black-level performance sharpens the picture by compensating the ambient light. In higher-end models of plasma, the picture quality is excellent.
The high refresh rate makes the picture smoother and omits the motion blur.
But plasma televisions have some disadvantages too. It consumes more power compared to other LCD TV. It is also slightly heavy. The TV screen, made of glass, can reflect light which decreases the viewing experience.
Main Differences Between HDTV and Plasma
