Do you remember “Plasma TV”? This TV technology has attracted attention because it can provide excellent picture quality. At the beginning, the author was also scratched by the exquisite display screen, but it was like a flash in the pan, and disappeared from the sight of consumers at once, just like Small stones into the water did not cause too much splash. What makes this TV technology disappear? If you still love the display of a plasma TV, what are the alternatives?
Do you remember “Plasma TV”? Why did it just disappear?
Before we get into the topic of the death of “plasma TV”, we must first understand it. So in this article, we not only want to mention why it disappeared, but also tell you how it works and all kinds of surrounding knowledge.
How Plasma TV Works
For the operation of plasma TV technology, we briefly explain. Plasma TV is a flat-panel display. Its basic working principle is similar to that of CRT and fluorescent lamps. Basically, plasma TV is composed of many small discharge units, and each small unit is responsible for one of the three colors of red, green and blue. The dissociated inert gas is used in the small unit. When the electricity passes through, the gas in it will ionize and emit ultraviolet rays, and then stimulate the red, green, and blue phosphors coated on the glass to emit corresponding colored light. The control of small units emits ultraviolet rays of different intensities, which can produce three primary colors with different brightness, and then form a variety of colors.
In essence, plasma TVs are self-illuminating and do not require a backlight, so they have excellent contrast, mainly because when deep blacks are required, individual small units can be turned off to obtain excellent image quality. In addition, plasma TV has the advantages of fast response time, high update rate, and wide viewing angle, so it was very popular among consumers when it was first launched.
What Caused the Demise of Plasma TV?
Although plasma TV has many advantages, there are also many disadvantages. For example, it cannot display brightly, so it is only suitable for viewing in a darker environment. Even the top-of-the-line plasma TVs peak at only 100 nits in the 10% window test, which is a far cry from the 1,000-plus nits peak brightness of modern top-of-the-line LED-backlit TVs. Although plasma TVs are also prone to temporary and permanent image burn-in or burn-in problems, improvements have been made as plasma technology has matured. Another point of plasma TV is the power consumption and waste heat produced. It must use a lot of power to drive it to operate, and it must install multiple fans inside to cool down. Therefore, although compared with CRT TVs, Light and thin, it is actually still a heavy thing.
Plasma TVs’ original competition with CCFL-backlit LCD TVs was disrupted with the advent of LED backlighting, which was thinner and required far less power to run. The original LED TVs lagged behind plasma TVs in terms of picture quality and viewing angle, but consumers knew that the disadvantages of plasma TVs obviously outweighed its advantages. The final straw that crushed plasma TVs was the introduction of OLED and 4K TVs. Plasma TV makers realized that trying to make a 4K plasma TV would require a huge investment that was not worth the effort, and that OLED TVs had most of the picture quality advantages of plasma TVs with few of the downsides.
By 2014, TV makers had effectively given up on plasma TVs and focused on LED-backlit LCD and OLED TVs, the types of mainstream TVs we’re now seeing flourish.
What Are the Best Alternatives to Plasma TVs?
In fact, OLED TV can be regarded as the spiritual successor of plasma TV, and it is also the best substitute for plasma TV. There are many common features between the two, and it is even better than plasma TV. For example, OLED TVs, like plasma TVs, have self-illuminating cells, so they can achieve near-infinite contrast ratios, which is not possible on plasma TVs. Although plasma TVs can produce deep blacks by turning off individual units, there will always be some charge in the plasma that has not completely disappeared so that there will be residual light when displayed, so plasma TVs cannot produce truly perfect blacks.
Like plasma TVs, OLED has excellent wide viewing angles and fast response time, and its screen display is brighter, and its volume is significantly thinner and lighter. Unfortunately, for OLED, aging is also an inescapable problem, but with the advancement of OLED technology and the protection mechanisms added by various brands in TVs, the problem of aging is no longer so easy for people watching various content Causing distress.
All in all, if you want to eliminate the plasma TV at home, OLED TV will be your best choice. OLED TVs are generally more expensive than their LED-backlit LCD counterparts, though, so if you’re on a tight budget, go for an LCD TV. Unlike plasma-era LCD TVs, many modern LCDs offer excellent contrast thanks to Mini-LED backlighting and full-array local dimming, and modern LCDs are fast.
write at the end…
Undoubtedly, plasma TV was the king of TV imaging technology before the turn of generations. Unfortunately, with the emergence of other competing TV technologies, plasma TV has too many fatal shortcomings that prevent it from surviving in the technological torrent. OLED is the successor and has even better performance. With more and more improved technologies, the current OLED is more friendly than the early price (compared with itself…), while also providing stunning display Effect.
