From tube television to oled, a technological history of television

Since the American inventor Philo Taylor Farnsworth introduced in 1927 a technology that broke down an image into 60 lines of light and transmitted it in the form of electrons and recomposed it in a TV with OLED screens with definition UHD 4K, many are the milestones the evolution of the device that occupies a special place in all homes and that fascinates us so much.

With the development of the first vacuum tube, Farnsworth gave birth to the era of electronic television, which would soon be nurtured by other important innovations. The color, for example, appeared in the 1960s, the remote in the mid-1980s and the flat screen in the late 1990s. Technological advances have become more common: tube TVs have made their way Plasma and this immediately succumbed to the LCD screen at the beginning of the new millennium. But far from slowing down, the evolution of the last two decades has further increased, especially in terms of connectivity and image quality, to the point of forever transforming the experience of the television.

In 2005, the 720-pixel high definition television, two years later the Full HD with 1080 pixels and in 2009 the first LED TV. But it is at the end of 2010 that Smart TV comes into play and television changes forever. And it's that this technology has not only completely revolutionized the way we watch TV, but has completely transformed the television content industry itself.

OLED: the last revolution of the screen

With the emergence in 2011 of 4K TVs, screens began to be the protagonists of the most recent technological revolution in television. The 2160 pixels delivered by these devices, also called Ultra HD (UHD), have taken the picture quality almost to the limit of the definition that can be perceived by the human eye.

And as if that were not enough, we are now starting to take advantage of OLED technology, which is perfectly complemented by the UHD 4K definition to found a new paradigm in TVs. The new displays have what is called "organic lighting", ie pixels capable of turning on and off independently (no need for LED panels). ), which allows the reproduction of absolute blacks, with an infinite contrast between lights and shadows, and many more vivid colors. But in addition, to the three colors green red and blue (RGB) of the previous technology, OLED adds a fourth color, white, expanding the chromatic scale by 30%. With this technology, it is possible to say that these new TVs offer for the first time in the history of perfect colors. Images without any distortion at any angle, sharpness and depth never seen before thanks to HDR technology, which gives a greater dynamic range of colors. In addition, it is considerably faster than LED TVs, ultra-thin screens and energy savings are the combined advantages of these new OLED TVs.

Parallel to this remarkable technological evolution, consumption over the years, especially Smart TV. Far from being the moment we waited for a day of the week to sit down to watch our favorite show. Today, he controls the culture of demand and streaming. But despite this, television has not lost popularity among older generations. According to a study by LG Electronics Argentina around the world, 90% of people over 65 consume television content. And in Argentina, the segment that spends the most time on television is that of adults over 50, who watch the content for 3.3 hours each day. This type of users has been able to adapt to each innovation and continue to enjoy the content through the commitment to inclusion and accessibility of companies such as LG, which develop very user-friendly visualization and control systems for less digitized generations.

Models available in Argentina

If before the latest technology in televisions took a long time to arrive in Argentina (we think it was only possible to see the colors in 1978), today this gap does not practically exist not. OLED technology with 4K UHD resolution is already available in our country through the LG B7P 4K 55 "Smart TV models and the LG B7P 4K 65" Smart TV. LG's OLEDs use an advanced panel with 33 million autonomous subpixels and a relationship that generates the revolutionary "infinite contrast". And all this in an ultra-thin display that does not exceed 6 mm in thickness. To see things as they are
