Which one is better LCD Monitors or LED Screen?

When you think of buying a new monitor for your computer, are faced with various offers and models as the most common LCD and LED monitors , but it certainly causes some doubts regarding the differences of these models , so check out these tips .

The LCD monitor has completely changed the way of playing compared to the CRT. This monitor does not use a cathode ray tube, but films of liquid crystal, which when energized, produce the spectrum of colors on the screen.

The big advantage that LCD monitors have brought computer users are: low power consumption , beyond the dimensions that were reduced , it was thinner and lighter , the non-emission of harmful radiation and the ability to form an image almost perfect , stable , flicker- less tiring vision, i.e. , has many points in its favor . But as not all flowers , it has a disadvantage , the disadvantage of the LCD monitor is its LCD screen if the screen is damaged or exposed to air , may emit toxic compounds – which can be a problem for the middle – environment.

Have LED monitors are LCD monitors developments. Because they are made with light-emitting diodes (LEDs) have the characteristic of being brighter, besides having a much higher contrast and more vibrant colors than LCD monitors.

With it you can tell that displays the LED base will surely dominate the scene from now on, mainly because they spend less energy.

Advantages and Disadvantages of LCD TVS, LED and plasma
In the case of plasma TVs, the screen works with cells filled with noble gas (such as neon or xenon) suffering an electrical discharge and turns into plasma.

This whole process releases photons (light) and collide with a phosphor layer in front of those cells that do shine. Each image point is composed of three cells, and each coated with a different phosphor color (red, green and blue).

The combination of these three different colors at varying intensities generates the tones required to produce the image. And the simple fact that each cell producing its own light, there is no need of any light to illuminate our screen.

Advantages of Plasma TV

The plasma TVs are more suitable for dark environments due to the higher color fidelity and contrast, which is very good for those who love movies because they offer more vivid and does not depend on light for this to occur , i.e. , they have a quality very good picture .

Are also very good for those who like to watch sports and more modern games because they offer what is called “dynamic resolution ” , which gives us better quality motion scenes .

Furthermore, plasma TVs is super indicated for large environments, as they are much easier and cheaper to be produced in larger sizes. No wonder we see there a lot of giant plasma TV in the windows of shops.

It is worth noting that there are components that can be very useful regardless of what TV you buy devices like Blu – Ray when watching a movie, HDMI cable, which is a great help in image quality, a Home Theater to watch that concert and so on. There are several options for you to be very happy with your choice; the important thing is that you really need to know what is important for you to be satisfied.

– Increased rate of wear and defects due to sources to excite the cells
– Increased electromagnetic emission – ultra violet light
– Device with deeper and heavier
– Difficulty mounting screens smaller than 40
– High power consumption
– To get too close to the screen, it generates a flicker effect that tire the fastest views
– Static images and black bars on the sides of the screen burn
– To be used as PC monitor is less than the LCD because of the resolution in pixels.

– Have more reflective than LCD, leaving a “mirrored” screen if there is direct illumination (open window, for example), a phenomenon also known as CRT monitors.


The LCD TV works with the base being a liquid crystal material, which gives a more translucent or opaque image depending on the electric current applied to it.

Each point on the screen is made up of three sealed cells filled with this material and each cell corresponds to a primary color of light (green, red and blue).

A lamp that generates white light is installed behind the screen and illuminates the cells making up the image.
The colors are thereby formed and thus combine multiple intensities of each of the primary colors.

Advantages of LCD TVs

The LCD TVs are now more suitable for brightly lit rooms, this means you can watch your program with a window behind your TV you will not see any reflection in the image, apart from plasma.
Are also indicated for those who will turn the PC on it or play those games more standing, as of old, for still images used to stain the older plasma TVs. You can also find LCDs available in smaller sizes, which is hard to find in the plasma models, like watching a TV over 42 inches in a small room.
They also consume less energy , are more efficient comparing them with the old tube televisions ( CRT ) , have a lower cost of maintenance of the plasma and CRT and better aesthetics , being thin and lightweight.

– Low resolution especially in analog composite video (cable TV)
– Reduced viewing angle
– Minimum illumination of constant black parts, reducing contrast
– Lack of uniformity of the backlight causing distortion of the image


The process of transmission of LED TVs works much like an LCD TV that technology is only slightly different, i.e., instead of that white light in the backlight, the LED TVs you have a set of LEDs with colors primary (red, blue and green) and makes the job of filtering the liquid crystal light is much better done, getting more pure and with a much wider range colors.

This technology also causes light to be exactly the same throughout its usage time and without loss of brightness or color change , regardless of whether or not a burning light. The panel also allows a better adjustment of light intensity.


The screens of LED TVs are much brighter , with much better contrast and more vivid when compared to the model of the LCD , i.e. , have a much better picture , because they are made with light-emitting diode ( LED ) . These TVs can also be much thinner than the other (since there are up to 3 cm thickness).

These TVs meet the standards Eco -friendly because it does not require lamps CCFLs and are completely mercury-free. Do not use lead to fixation of components and makes the disposal and recycling of TVs can be made safely and without impacting the environment.

The LED televisions also meet Energy Star standards, as they have a very low level of power consumption up to 40 % less than the LCD TVs of the same size. What is very good for our pocket? Have more uniform backlight, better resolution on component and HDMI video and are extremely thin, because the LED occupy less space than the lamp (back light).


While a device Full HD 42-inch LCD can be found for prices starting from $ 3,000 , the price suggested by Samsung for a 40-inch model is salted Led R $ 6,999 , which may scare away some customers . According to Samsung, the high local value is justified by the device, which technology – as always – is expected to fall in the future. For now, those seeking a bargain without sacrificing LED technology should be content with the 32-inch model, which can be found by R $ 4,799. – Wikipedia
