Micro LED: The Future of TV Displays?

Micro LED is a self-emissive technology like the OLED display. Under this technology, each pixel generates its own light which allows you to control the brightness and color at the pixel level. Instead of using organic light emitting diodes, the Micro LED display uses non-organic LEDs- 3 per pixel. This enables each pixel to be turned on or off individually and display a different color or brightness to the pixel next to it. This leads to exceptional contrast and color control. Micro LED displays can reach much higher brightness levels compared to OLED and are more energy-efficient also.

Benefits of Using Micro LED Display

The first advantage of using Micro LED over OLED is increased brightness. Brightness levels of Micro LED can go up to 10,000 knits, compared to a peak brightness of 1000 knits on OLED. Micro LED is not organic like OLED which gives them a longer lifespan. OLED displays will deteriorate and fade over time while Micro LED displays can last up to 100,000 hours which is essentially 11 years of non-stop playing. Another advantage of using Micro LED display in TVs is their energy efficiency as there is no need of using a color filter for optimizing the brightness levels. Micro LED display in TVs will also lead to near bezel less screens and excellent viewing angles.

Challenges in Developing Micro LED Display

Developing Micro LED displays involves its own challenges. When the LEDs are shrunk, the light they produce also reduces. You will need to either drive them harder or increase their efficiency or do both. Driving harder may lead to more heat dissipation and energy consumption. Shrinking the pitch size (the gap between the pixels) is also difficult as the circuitry can only be reduced up to size. Manufacturing these displays is expensive too as there are 3 time more pixels than in a normal display.

Commercial Viability

Micro LED display in TVs is not commercially viable at the moment. Samsung launched a 219-inch massive Micro LED Display in their TV at the CES 2019, which they named as “The Wall”. Such large displays will have very few buyers and unless manufacturers can come up with normal sized displays, this technology cannot go mainstream. Manufacturing a 40-inch Micro LED display will be very costly currently. However, with technological advancement, the cost of manufacturing these displays can be reduced over time. It is estimated that by 2026, 16 million units on Micro LED display TVs will be shipped globally.
