The world of television technology has undergone significant transformations over the years, with various types of displays vying for dominance. One of the most popular and widely used technologies is LCD (Liquid Crystal Display), which has been a staple in the TV industry for decades. However, with the advent of newer technologies like OLED and QLED, the question on many people’s minds is: are LCD TVs good?
The Basics of LCD TVs
Before diving into the pros and cons of LCD TVs, it’s essential to understand how they work. LCD TVs use a layer of liquid crystals to block or allow light to pass through a matrix of pixels. The liquid crystals are controlled by an electric current, which aligns them to create images on the screen. The backlight, typically an array of LEDs, provides the necessary illumination for the images to appear.
LCD TVs can be further categorized into different types, including:
Twisted Nematic (TN) Panels
TN panels are the most common type of LCD panel and are known for their fast response time and low cost. However, they often suffer from limited viewing angles and mediocre color reproduction.
Vertical Alignment (VA) Panels
VA panels offer better contrast ratios and deeper blacks compared to TN panels. However, they can exhibit slower response times and may suffer from backlight blooming.
In-Plane Switching (IPS) Panels
IPS panels are renowned for their excellent color accuracy, wide viewing angles, and good brightness. However, they can be more expensive than TN panels and may have slower response times.
Pros of LCD TVs
Despite the emergence of newer technologies, LCD TVs still have several advantages that make them a popular choice among consumers.

Backlight blooming is a common issue in LCD TVs, where the backlight can cause an uneven distribution of light, leading to a decrease in picture quality.
Comparison to Other Technologies
To better understand the strengths and weaknesses of LCD TVs, let’s compare them to other display technologies.
OLED TVs
OLED (Organic Light-Emitting Diode) TVs use a different technology to produce images. They don’t require a backlight, as the pixels emit their own light. This results in:
- Infinite contrast ratios, as true blacks are achievable
- Wider viewing angles, with minimal degradation in picture quality
However, OLED TVs can be more expensive than LCD TVs, and they may be prone to image retention (also known as burn-in).
QLED TVs
QLED (Quantum Dot Light Emitting Diode) TVs use tiny crystals to create colors, resulting in:
- Better color accuracy and a wider color gamut
- Higher brightness levels and improved contrast ratios
QLED TVs are also more expensive than LCD TVs, and they may not quite match the contrast ratios of OLED TVs.
Are LCD TVs Good?
So, are LCD TVs good? The answer is a resounding yes, but with some caveats. LCD TVs can offer excellent picture quality, low power consumption, and affordability, making them a great option for:

By considering the strengths and weaknesses of LCD TVs, you’ll be better equipped to make an informed decision when choosing your next TV.
What is an LCD TV and how does it work?
An LCD TV, or Liquid Crystal Display TV, is a type of flat-panel display that uses a layer of liquid crystals to block or allow light to pass through a matrix of pixels. This creates the images that are displayed on the screen. LCD TVs use a backlight to illuminate the liquid crystals, which are essentially tiny shutters that open and close to control the amount of light that passes through.
The liquid crystals are arranged in a grid, with each pixel made up of three sub-pixels, one for each primary color (red, green, and blue). The combination of these sub-pixels and the amount of light allowed to pass through determines the final color and brightness of each pixel. This technology allows LCD TVs to display a wide range of colors and contrast levels, making them suitable for a variety of viewing applications.
What are the advantages of LCD TVs?
One of the main advantages of LCD TVs is their energy efficiency. They use significantly less power than traditional CRT (cathode ray tube) TVs, making them a more environmentally friendly option. Additionally, LCD TVs are typically thinner and lighter than CRT TVs, making them easier to move and install. They also tend to be more affordable than other types of flat-panel displays, such as OLED (organic light-emitting diode) TVs.
Another advantage of LCD TVs is their wide viewing angle. This means that the picture remains clear and vibrant even when viewed from the side, making them a great option for families or groups of people who want to watch TV together. LCD TVs also tend to have lower glare and reflection than other types of displays, making them suitable for bright rooms or areas with lots of natural light.
What are the disadvantages of LCD TVs?
One of the main disadvantages of LCD TVs is their limited contrast ratio. This means that they can struggle to produce true blacks, which can result in a lower overall contrast and a less immersive viewing experience. Additionally, LCD TVs can suffer from limited viewing angles, which can cause the picture to degrade when viewed from the side. This is particularly noticeable in scenes with bright colors or high contrast.
Another disadvantage of LCD TVs is their potential for motion blur. This occurs when the liquid crystals take too long to switch on and off, resulting in a blurry or smeary effect during fast-moving scenes. This can be particularly noticeable in sports or action movies. However, it’s worth noting that many modern LCD TVs have features such as motion interpolation and black frame insertion to help mitigate this issue.
How do LCD TVs compare to other types of TVs?
LCD TVs are often compared to OLED TVs, which use a different technology to produce the images on the screen. OLED TVs use an emissive technology, where each pixel produces its own light, whereas LCD TVs use a transmissive technology, where a backlight illuminates the liquid crystals. OLED TVs tend to have better contrast and black levels than LCD TVs, as well as faster response times and wider viewing angles.
However, OLED TVs tend to be more expensive than LCD TVs, and can be more prone to image retention (also known as burn-in). Plasma TVs are another type of display that is often compared to LCD TVs. Plasma TVs use individual cells filled with a gas, such as neon or xenon, which are electrically charged to create the images on the screen. They tend to have better contrast and black levels than LCD TVs, but can be heavier and more power-hungry.
Are LCD TVs good for gaming?
LCD TVs can be a good option for gaming, depending on the specific model and features. Many modern LCD TVs have low input lag, which means that the time it takes for the TV to process the signal from the gaming console is minimized. This can result in a more responsive and immersive gaming experience. Additionally, many LCD TVs have features such as motion interpolation and black frame insertion, which can help reduce motion blur and improve the overall picture quality.
However, LCD TVs may not be the best option for gamers who require extremely fast response times and low input lag. OLED TVs, for example, tend to have faster response times and lower input lag than LCD TVs, making them a better option for serious gamers. Ultimately, the suitability of an LCD TV for gaming will depend on the individual’s specific needs and preferences.
Can LCD TVs be used outdoors?
LCD TVs can be used outdoors, but they may not be the best option for several reasons. Firstly, they can be sensitive to bright light, which can cause the screen to become washed out or difficult to see. Secondly, they can be prone to glare and reflection, which can further reduce the picture quality. Finally, LCD TVs are typically designed for indoor use and may not be weather-resistant or durable enough to withstand the elements.
However, if you still want to use an LCD TV outdoors, there are some models that are specifically designed for outdoor use. These TVs are typically more rugged and weather-resistant than standard LCD TVs, and may have features such as higher brightness and anti-glare coatings to help improve the picture quality in bright light.
What is the future of LCD TVs?
The future of LCD TVs is likely to be shaped by advances in technology and changing consumer preferences.
