In the not-so-distant past, projection TVs were hailed as the future of home entertainment. With their ability to produce massive screens and immersive viewing experiences, they were the go-to choice for many consumers. However, in recent years, projection TVs have all but disappeared from the market. So, what happened to this once-promising technology?
The Early Days Of Projection TVs
To understand the rise and fall of projection TVs, it’s essential to look back at their early days. The first projection TVs were introduced in the 1970s, using CRT (cathode ray tube) technology. These early models were bulky, expensive, and prone to maintenance issues. However, they paved the way for future innovations.
In the 1990s, projection TVs started to gain popularity with the introduction of rear-projection TVs (RPTVs). RPTVs used a combination of CRTs and lenses to project images onto a screen. They were more affordable and compact than their predecessors, making them a viable option for home entertainment.
The Advent Of Digital Projection TVs
The early 2000s saw the introduction of digital projection TVs, which used digital light processing (DLP) technology. DLP TVs used a digital micromirror device (DMD) to project images onto a screen. They offered improved picture quality, higher contrast ratios, and faster response times.
Around the same time, liquid crystal on silicon (LCoS) technology emerged. LCoS TVs used a liquid crystal layer to block or allow light to pass through a silicon substrate. They offered excellent picture quality, high contrast ratios, and fast response times.
The Rise Of Flat-Panel Displays
As the 2000s progressed, flat-panel displays (FPDs) started to gain popularity. FPDs, including plasma TVs and LCD TVs, offered slim designs, low power consumption, and improved picture quality. They were also more affordable and widely available than projection TVs.
The rise of FPDs marked the beginning of the end for projection TVs. As FPDs improved in quality and decreased in price, consumers began to favor them over projection TVs. The market for projection TVs started to decline, and manufacturers began to shift their focus to FPDs.
The Impact Of 3D Technology
The introduction of 3D technology in the late 2000s and early 2010s further accelerated the decline of projection TVs. While some projection TVs supported 3D, they were not as effective as FPDs in delivering an immersive 3D experience.
FPDs, particularly LCD TVs, were better suited for 3D technology. They offered faster response times, higher refresh rates, and improved brightness, making them ideal for 3D viewing.
The Final Nail In The Coffin: LED And OLED TVs
The introduction of LED and OLED TVs in the late 2000s and early 2010s marked the final nail in the coffin for projection TVs. LED TVs, which used an array of LEDs to illuminate an LCD panel, offered improved picture quality, higher contrast ratios, and faster response times.
OLED (organic light-emitting diode) TVs, which used an emissive technology to produce images, offered even better picture quality, higher contrast ratios, and faster response times. OLED TVs were particularly effective in delivering true blacks, as each pixel could be turned on and off independently.
The Decline Of Projection TV Sales
As LED and OLED TVs gained popularity, projection TV sales continued to decline. According to a report by DisplaySearch, global projection TV sales peaked in 2007 at around 14.5 million units. By 2012, sales had declined to around 2.5 million units.
In 2013, major manufacturers such as Samsung, Sony, and Panasonic announced that they would be discontinuing their projection TV lines. This marked the end of an era for projection TVs, which had once been hailed as the future of home entertainment.
What Went Wrong?
So, what went wrong for projection TVs? Several factors contributed to their decline:
- Cost: Projection TVs were often more expensive than FPDs, particularly in the early days. As FPDs improved in quality and decreased in price, they became a more attractive option for consumers.
- Size and weight: Projection TVs were often bulky and heavy, making them difficult to move and install. FPDs, on the other hand, were slim and lightweight, making them easier to handle.
- Maintenance: Projection TVs required regular maintenance, including lamp replacements and filter cleaning. FPDs, on the other hand, required little to no maintenance.
- Picture quality: While projection TVs offered excellent picture quality, FPDs eventually caught up and surpassed them. LED and OLED TVs, in particular, offered better picture quality, higher contrast ratios, and faster response times.
Legacy Of Projection TVs
Although projection TVs are no longer a viable option for home entertainment, they left a lasting legacy. They paved the way for future innovations in display technology, including FPDs and 3D TVs.
Projection TVs also played a significant role in the development of home theaters. They enabled consumers to create immersive viewing experiences in the comfort of their own homes, which helped to drive the growth of the home theater market.
Conclusion
The rise and fall of projection TVs is a cautionary tale of how quickly technology can evolve and how important it is to adapt to changing market trends. While projection TVs were once hailed as the future of home entertainment, they ultimately failed to keep pace with the rapid advancements in FPDs.
Today, FPDs, including LED and OLED TVs, dominate the market. However, it’s essential to remember the role that projection TVs played in shaping the display technology landscape. As we look to the future, it will be interesting to see what new innovations emerge and how they will shape the world of home entertainment.

What Is A Projection TV And How Does It Work?
A projection TV is a type of television that uses a projector to display images on a screen. It works by using a lamp or laser to produce light, which is then directed through a digital micromirror device (DMD) or liquid crystal on silicon (LCoS) chip. The DMD or LCoS chip is made up of thousands of tiny mirrors or pixels that reflect the light to create the images on the screen.
The images are then magnified and projected onto the screen using a lens system. Projection TVs were popular in the 1990s and early 2000s because they offered a large screen size at a lower cost than traditional CRT TVs. However, they had some limitations, such as a lower contrast ratio and a limited viewing angle.
What Were The Advantages Of Projection TVs Over Traditional CRT TVs?
Projection TVs had several advantages over traditional CRT TVs. One of the main advantages was their larger screen size. Projection TVs could produce screens of up to 100 inches or more, while CRT TVs were typically limited to around 36 inches. Projection TVs were also thinner and lighter than CRT TVs, making them easier to move and install.
Another advantage of projection TVs was their lower cost. While high-end projection TVs could be expensive, entry-level models were often priced lower than CRT TVs of the same size. Additionally, projection TVs were often more energy-efficient than CRT TVs, which made them a more environmentally friendly option.
What Were Some Of The Limitations Of Projection TVs?
Despite their advantages, projection TVs had some significant limitations. One of the main limitations was their lower contrast ratio. Projection TVs struggled to produce true blacks, which made them less suitable for watching movies or other content that required a high level of contrast. They also had a limited viewing angle, which meant that the image would degrade if viewed from the side.
Another limitation of projection TVs was their lamp life. The lamps used in projection TVs had a limited lifespan and needed to be replaced every few thousand hours. This could be expensive and inconvenient. Additionally, projection TVs were often prone to dust buildup, which could affect the image quality.
What Role Did The Rise Of Flat-screen TVs Play In The Decline Of Projection TVs?
The rise of flat-screen TVs, such as plasma and LCD TVs, played a significant role in the decline of projection TVs. Flat-screen TVs offered a number of advantages over projection TVs, including a thinner and lighter design, a wider viewing angle, and a higher contrast ratio. They also eliminated the need for a lamp, which made them more energy-efficient and reduced maintenance costs.
As flat-screen TVs became more affordable and widely available, they began to gain popularity over projection TVs. Many consumers preferred the sleek and modern design of flat-screen TVs, as well as their improved image quality. As a result, sales of projection TVs began to decline, and manufacturers started to focus more on producing flat-screen TVs.
Did The Rise Of Home Theaters Contribute To The Decline Of Projection TVs?
The rise of home theaters did contribute to the decline of projection TVs, but not in the way you might think. While projection TVs were often used in home theaters, the rise of dedicated home theater projectors actually hurt the sales of projection TVs. Home theater projectors offered better image quality and more features than projection TVs, making them a more popular choice for home theater enthusiasts.
As a result, many consumers who were interested in a big-screen viewing experience opted for a dedicated home theater projector instead of a projection TV. This reduced demand for projection TVs and contributed to their decline. Additionally, the rise of home theaters also led to an increase in the popularity of other display technologies, such as LCD and plasma TVs.
Are Projection TVs Still Available For Purchase Today?
While projection TVs are no longer as widely available as they once were, they can still be purchased today. However, the selection is limited, and most projection TVs are now marketed as “home theater projectors” rather than traditional TVs. These projectors often have more features and better image quality than traditional projection TVs, but they may not have the same level of convenience or ease of use.
Some manufacturers, such as Epson and BenQ, still produce projection TVs, but they are often targeted at specific niches, such as home theaters or gaming. Additionally, some retailers may still carry older models of projection TVs, but these are often discontinued and may not have the same level of support or warranty as newer models.
What Can We Learn From The Rise And Fall Of Projection TVs?
The rise and fall of projection TVs teaches us the importance of innovation and adaptability in the technology industry. Projection TVs were once a promising technology, but they failed to keep pace with changing consumer demands and advances in other display technologies.
