Tech InDepth: Everything you need to know about OLED TVs


OLED TVs like the new Xiaomi OLED Vision TV are becoming increasingly popular in India. These large, expensive and often feature-rich TVs boast lifelike picture quality unlike anything you’ve seen before due to super deep blacks and vivid colors. However, what are OLED TVs, how do they work and how are they different from regular LCD/LED TVs?

Here are some of the questions we’ll be answering in today’s edition of Tech InDepth.

What are OLED TVs?

The regular TVs that most people have been using for a decade are LCD or LED TVs. These are televisions with a fixed light source, a dedicated LCD diffuser panel and finally, a layer made up of many small pixels.

On an LCD TV, a common light source at the back illuminates all of the pixels, and it’s the LCD panel in the middle that dictates which pixels display which color. Multiple colors across multiple pixels then make up the image we see.

A similar operation powers LED TVs (which, contrary to popular belief, are not made up of multiple individual LEDs). These are actually LCD TVs powered by LED backlights. These backlights can be grouped into zones and can therefore darken or lighten certain parts of the whole screen, which the ordinary LCD TV cannot do.

However, none of these TVs come close to the picture quality of OLED TVs and that’s largely down to one reason, or one color to be precise – black. To produce true black, a light-emitting source must be completely turned off. However, this is not possible on LCD and LED TVs where the backlight is common to a group of pixels or the whole TV. This is why black areas are considered grayish shades on LCD and LED TVs.

This inability to show true black affects not just one color, but most of them. Blacks decide how dark a particular shade of red, blue, or pink is on screen, but with the limitations of LCD and LED, the color inaccuracy of blacks also carries over to the most other shades, which doesn’t give you the best output image. in terms of color accuracy.

That’s where OLEV TVs come in. On OLED display panels, each pixel creates its own light, instead of relying on a backlight. This is done using organic compounds that glow in a particular hue when current is applied.

No common backlight means that each pixel in the TV is independent not only in color, but also in brightness. Every pixel in an OLED TV can reproduce true black by simply lowering its intensity (or turning it off completely) and as a result, all shades of various other colors also appear much more accurate and realistic.

OLED TVs to consider under Rs 2,00,000

Now you know how OLED TVs work, but which ones should you choose? The technology that goes into creating the OLED panel makes these TVs very expensive compared to regular TVs. If you don’t want to spend too much, here are some OLED TVs that you can find under Rs 2,00,000.
