If you are not familiar with new television technologies, the effort to understand and select all available options can be overwhelming. What is the best for you to watch TV? LCD, LED, or 3D? If the answer was so easy! Unfortunately, there are many types in each of the above categories.
This means that long comparisons with many titles and subtitles will definitely follow, but is it really more useful than reading the details (mostly unfamiliar) of the various models offered? I do not think so! Now let’s make it easy to compare these technologies for those of us who aren’t tech gurus but are looking for a solid foundation for buying the perfect TV.
Liquid crystal television
LCD TVs are televisions that use LCD display technology and LED screens from LED suppliers to generate images. Energy-efficient technology uses a cell filled with liquid crystal between two glass plates and a fluorescent backlight. Light is emitted through thin film transistors that transmit different amounts of light to cells filled with liquid crystal displays.
LCDs are sensitive to light-the lighter they receive, the darker they are. Images are displayed on the screen in black and white or in color, thanks to color filters that capture the light intensity of the LCD.
- Thin and light available in larger sizes.
- Low consumption.
- Widely created and available.
- Low contrast ratio: Less detail in dark areas of the image.
LED TVs are technically part of the LCD TV family. The LED from the LED screen supplier is an LCD screen like any other LCD TV. The main difference between the two is the difference in backlight technology, which can significantly change image quality characteristics.
LCD TVs use some form of fluorescent lighting, while LED TVs use light-emitting diodes to illuminate the LCD panel. Just as traditional LCD TVs have different styles of fluorescent lights, so do LED backlights. Some LED TVs have a panel of LED lights behind the LCD panel. These LEDs are three colors and can be bank driven for an effect called “local dimming”.
This darkens the backlight in the dark areas of the image, improving contrast and black level. Other LED TVs work like traditional LCD TVs. On these TVs, LED lights wrap around the edges of the panel, allowing for very shallow depths, but without the possibility of local dimming.
- Thin and light available in larger sizes.
- Higher Contrast Ratio-Good image detail.
- 3-color LED makes screen colors more realistic.
- LEDTVs around the edge consume less power than LCD TVs.
- Local dimming LED TVs to consume more power than LCD TVs.
Asking the value of an LED screen is like asking the value of a car. There is only one answer to such questions. Dependent. For the five variables:
1-Size: Do you need a smart car or a BMW X5 (i.e. what sizes of LED screens do you want to install?)
2-Power: Do you want to drive it on a circuit or just need it to get things done? (I mean what is the resolution of the LED screen?) Note for beginners: Resolution = distance between pixels: The closer the pixels, the better the image with the shorter display distance.
3-Reliability: Luxury car brands use luxury materials, which can provide greater warranty (i.e. LED screen supplier).
4-Entry: How much value do you place on Toyota’s world-class service? (I mean, watch out for Asian start-ups with proven technology and no history)
5-Training: BMW offers a two-day safe driving seminar to all customers purchasing the new sport line. (i.e., know which LED screen supplier either doesn’t provide training on how to use the screen effectively or provides minimal training).
Before buying an LED screen, ask yourself these questions and rank them according to the importance of each element. This way you can easily determine the perfect screen and manufacturer details and profile you are looking for.

Well, here are some actual numbers if you need exact numbers:
1-Size: The lowest LED screen supplier size I recommend is 2 x 1.5 meters: this of course depends on the pixel size, but it is generally the lowest size I recommend.
2-Power: The best value I would suggest is 10mm: again, the resolution depends on the viewer’s average viewing distance, but 10mm is generally safe.
3-Reliability: The warranty must be at least 2 years. Some entry-level products may have a one-year warranty. If this is the product you are looking for, make sure there is a maintenance contract. If so, beware of companies that charge 25% of their screen costs for maintenance starting in the second year, which may mean they think they are putting their products at risk.
