Evolution of TV: why OLED screens are so cool
Technologies / / December 19, 2019
In my childhood, the very existence of the family color television was considered prestigious. Now electronics stores are crowded heaped widescreen panels, feed their images of incredible quality. And among them there are the category TV, the picture which looks especially beautiful and realistic. We will talk about the evolution of the modern TV and explain why OLED-screens - that's the best you can buy today and in the near future.
Previously, color picture on the screen itself causes pleasure. We did not notice the shortcomings of the old TV sets, because I do not see anything better. Everything changed with the advent of LCD-screens and plasma screens. The first LCD did not differ a good image quality, and small viewing angles even aggravate the situation more. But these screens are flat, light and compact are!
In order not to miscalculate with the purchase of a TV today, you need to know about how the industry will develop TV tomorrow. Think 4K resolution - this is the maximum of what can technology? Not. Generally, the resolution - this is an important but not the only option. For many years, manufacturers have competed in the race of quality, while she LCD technology does not put her in the ceiling of its capabilities.
All LCD TVs are now good, but not perfect. They boast and high resolution, and a decent picture, but they have one important quality - realism. Blinding sun that causes squinting. Dark scene is causing anxiety creeps. Future TV for ultra-realistic color reproduction and brightness ranges unimaginable.
This black color
For years, engineers have struggled to solve the problem of the color of confidence. It seemed that the maximum realism can be achieved by increasing the brightness and juiciness of the picture, but it did not work for black.
This black color - it's not the light, and its absence. Black objects are those of us that reflects the least light and hence the TV screen, applying for a realistic image, it must be able not only to shine brightly, but did not shine at all.
OLED-screen feature that each pixel in it operates independently. To transfer the black pixel is turned off, ie ceases to emit light. To understand the benefits of this technology is enough to remember what it looks like the night sky in the woods and in the big city.
In the city, we almost did not see the stars, and the whole sky seemed filled with monotonous dim light. This reflected the lights of lanterns, light from the windows, and other attributes of a megacity. And just to be away from civilization, you can enjoy the true beauty of the night sky. Every star, every celestial body visible and stand out from the vast blackness of space.
lights of the city - this is the backlight LCD-screen that reduces the contrast of the image and depriving many details.
To fully experience the superiority of OLED easier when put side by side for comparison, a conventional LCD-TV. You see the difference?
You might think that the need to reliably convey the black color is rare, but try one word to describe such masterpieces of cinema like "Interstellar", "Star Wars", "Batman" from Nolan (Christopher Nolan) and creativity Tim Burton (Tim Burton). Yes, all of these movies are dark, and, unfortunately, a few of us have had the pleasure to see them for real. OLED-TV can correct this omission.
