The earliest version of TV was CRT, known as the “Braun tube.” It accelerated and deflected electron beams onto the screen to create an image, and used one or more electron guns to view the image.
Though it was only broadcast in black and white, people were excited about this new invention that they had never seen before.
Colour TV came about with the addition of the colour filter. Since that time, TV has become an essential item in the living room. To enjoy programming with family and others, people began to demand larger screens.
However, colour TVs with large screens were problematic, because larger, wider screens, required a bigger tube and thicker glass to correct the angle of the image and present a clear picture.
The Plasma Display Panel (PDP) TV made larger TVs possible.
PDP TVs allow RGB pixels to edit light by means of electronical discharges. With the new technology, PDP TV could be a flat panel display – and larger.
However, PDP has disadvantages of more energy consumption, a buzzing noise and overheating.
LCD, or Liquid Crystal Display, is an electronic visual display in which a layer of liquid crystals is arrayed in front of a CCFL backlight to produce images. The LCD TV was able to overcome many of the PDP TV’s shortcomings.
However, due to the backlight, LCD TVs could not express pure black, which limited the image quality.
For better clarity on a large screen,
LCD TVs applied an LED backlight and raised the resolution.
The Quantum Dot produced today is one type of LED TV.
However, more pixels meant more energy consumption,
and the ever-present backlight caused a halo effect
so the picture quality was still lacking.
As TV has evolved, the main objective has been the representation of a true-to-life picture. And now, a truly realistic picture on a bigger screen has finally come to life with the OLED TV.
The difference in TV picture quality came from the pixel quality itself, not the number of pixels. To achieve that, the OLED TV utilizes a simple structure without a backlight.
With thousands of independently lighting pixels, the OLED TV can control the light and express black to perfection. And, with an infinite range of contrast, the OLED TV can represent previously unseen detail in every image. This is the promise of the OLED TV – superior picture quality on the thinnest display.
LCD/LED TVs create an image using a backlight and other devices.
Light shines through a filter to create different colours, but interference can cause distortion on the actual display.
However, the OLED TV creates a totally different experience.
Just like the firefly naturally emits light, the OLED TV utilizes organic compounds for its independently lighting pixels.
The OLED TV is the ultimate solution that eliminates the backlight,
creating perfect black and perfect colour with high contrast and no distortion.
Perfect Black brings out the marvelous wonders of Perfect Color,
presenting the inherent beauty and expressing in each scene to multiply the emotions.
LG OLED TV offers vivid colors over 1 billion generated by 10-bit panel.
Infinite contrast is also important in expressing HDR
and perfect control of the light is the key to infinite contrast.
The infinite contrast range of the OLED TV with Perfect Black is ideal for HDR contents.
As you can see in the image below, OLED TV’s infinite contrast is superior to LCD in representing the darker parts of an image.
OLED TVs can reproduce over 21 stops of brightness compared to just 14 for the best LCD TVs.
The wider Dynamic Range of the OLED TV makes it possible to see details that cannot be seen on an LCD TV,
and this ultimately makes a difference between HDR and Active HDR.
Aiming for excellence far greater than just a viewing experience.
Merged perfectly with the wall, LG SIGNATURE OLED TV W is like
a window to another world. Immerse yourself in a picturesque reality.
Hailed as “King of TV”, “Holy Grail of TV”,
LG OLED TV breaks new ground.
