A true black can be created by an OLED or plasma display, which emits its own light. Grayscale is the result of LCD backlights, which make black appear gray. Plasma TVs no longer exist today, but LED-backlit LCD screens have replaced CCFL screens.
Many of the display technologies available today make modern understanding terminology difficult. The purpose of this article is to clarify these differences. The production of plasma TVs has ceased, as previously stated.
A major reason for the popularity of plasmas is their exceptional picture quality, true blacks, and quick response times. The reflective screen was also too bright and caused the color to fade. LCD TVs lack the same level of black as plasma TVs, but they are gradually replacing them due to their cheaper prices and thinner design.

LCD vs OLED vs PLASMA Difference
OLED (Organic Light Emitting Diode)
True black can be reproduced by OLED monitors and TVs similar to plasma displays. Furthermore, their excellent viewing angles guarantee that the picture does not change color or contrast when viewed from a skewed angle. A number of issues plagued OLED displays at first, including input lag, bad image burn-in, and high prices. Modern displays, however, have been able to resolve these problems. OLED TVs nowadays come with a variety of software, such as pixel refreshers and screen savers, to help with image retention. With a dedicated Game Mode, responsive gameplay is assured, as well as minimal input lag. In addition, they have dramatically reduced their prices. Despite being quite expensive, they are extremely valuable. There are only a handful of OLED monitors available at the time of this writing.
LCD (Liquid Crystal Display)
Generally, LCDs are categorized into two types. In older models, cold cathode fluorescent lamps (CCFL) provided backlighting. The LED backlight in modern LCDs consumes less power and allows the display to be thinner; however, LCDs of the past lacked this feature. A LED TV can be equipped with either an IPS or a VA panel. LCD monitors can have TN panels or IPS panels. Images of different types have different qualities. A wide range of viewing angles and colors are available on an IPS display. In terms of contrast ratio, VA panels are the best choice. Gaming monitors often use TN panels since they respond quickly.
Quantum Dots
With their quantum dot technology, Samsung QLED TVs have become popular. Thus, the image quality on display is enhanced. Though the term “QLED” may seem misleading, these TVs do not employ OLED technology. Quantum dots are embedded in standard LED TVs. OLED also boasts the advantage of infinite contrast when compared to QLED. Both LED, and OLED TVs are high-end TVs, so OLED is also more affordable. The buying guide we have dedicated to televisions can help you compare models.
Local Dimming
There’s a feature called local dimming on some LED TVs that are designed to make them look better with grayish blacks and limited contrast. In dimming, the dark portions of the screen are not affected, while the brighter portions of the screen are dimmed. The effects of this in LCD TVs can be wonderful, especially if the results are well executed. On the other hand, if local dimming settings are not properly implemented, they can create undesirable defects, like bloom and halo. To receive the best results, you should opt for a TV with full-array local dimming rather than edge-lit local dimming.
4K Ultra HD & HDR
High-resolution LCD TVs with OLED and LED backlighting are currently available. A 4K ultra HD television delivers a sharper picture than a 1080p HDTV does. In high-end TVs, you’ll find HDR (High Dynamic Range) technology, which enhances the color, contrast, and brightness of compatible content.
Conclusion
There are no longer any plasma or CCFL LED TV options, which means that your only option will be an OLED or LED LCD TV. Buying OLED is worth the investment in case you have a budget for premium television. The backlight of LED monitors is almost universal. Other specifications, such as the refresh rate and the type of display, should also be considered.
