TELEVISION man-ufacturers in the  Quantum Light-emitting Diode, QLED, a variation of LED/Liquid Crystal  Display, LCD, and the  Organic Light-emitting Diode, OLED, have intensified the quest to upstage each other with cutting–edge technology and digital features aimed at increasing product flexibility and improved consumer experience.

Some of the innovative features include their emissive display technology, thinness, lightness and viewing angle.

Other innovations include, Response time and lag (response time refers to the time it takes for each diode to change from “on” to “off”), with faster response time comes less motion (picture) blur; Low power consumption; and Black level technology, which is the ability of the TV to produce deep dark black colour which is an important factor in achieving excellent picture quality, higher contrast and richer colour and more realistic and dazzling image.

The technological innovations are also complemented with marketing strategies including celebrity endorsements and advertisements in various media platforms.

Driving these innovations are major brands namely: LG, Samsung  and  Sony. The fierce competition among them is reflected in the rapid introduction of new designs which come in different sizes and prices.


Vanguard Companies and Markets, C&M findings on the competitive differences of both TV technologies showed that when both TVs were pitched against each other on elements such as contrast, viewing angle, brightness and other performances, the following subsist:

Power consumption –  OLED TV panels are extremely thin and require no backlight and also require less power, making them more efficient.

Size –  OLED  TVS are lighter in weight than QLED.

Lifespan –  QLED/LED  or  LCD  TVs last longer than  OLED  TVs.

Viewing angle –  OLED  screens can be viewed with no luminance degradation at drastic viewing angles, up to 84 degrees compared to  QLED TVs, which have been tested to allow for a maximum viewing angle of 54 dgrees at best, so  OLED has a clear advantage.

In addition to promising stellar picture performance, QLED TVs are based on a modular system. They come in smaller screen size and not that costly like OLED.

For now, since this is a brand-new technology, the manufacturers are offering QLED TV in a huge, 146-inch package. But, as has always been with massive first-time introductions, the tech in the TV will trickle down to smaller and less expensive TVs over the next few years.

Distributors speak

A distributor, Managing Director of Jahbros Nigeria Enterprises in Agbara, Ogun State, Jamike Agbarakwu said: “When OLED TVs first arrived in 2013, they were lauded for their perfect black levels and excellent colour, but took a bit of a hit due to brightness levels that could not compete with  LED/LCD TVs. There were also a huge price gap between OLED TVs and LED/LCD. That has all changed. OLED TVs are much brighter than they used to be and the prices have come down, but LED TVs still have some distinct advantages.”

Another distributor, Ebube Nwigbo of Mazix and Brothers Enterprises, Ojota, Lagos, said:  “OLED TVs are thin, light and expensive at least when compared to QLED TVs of the same size. Both acronyms are only one letter apart. Can they really be that different? Yes, but it does not automatically mean that an  OLED will beat a  QLEDTV in every case.”

Companies’ reaction

Effort made to speak with Samsung country representative proved abortive as the calls were not picked, and the e-mail addresses kept bouncing back when their reaction was sought as regards the statement credited to the company’s President, Han Jong-hee, on Visual Display Business.

An expert who works in one of the competing brands who pleaded anonymity said: “Currently, LG is the only company that manufactures OLED panels for TVs. Sony  and LG had an agreement which allows Sony to put LG OLED panels into Sony TVs like the Bravia series.

“The difference in performance between LG’s OLED TVs and Sony’s result from different picture processors –  LG’s Alpha series and Sony’s X1 series. Top manufacturers, Samsung, Sony  and  LG  have better processors than other competitors, which is why two TVs with the same panel can look different. A good processor can reduce challenges like inaccurate colour presentation (banding) and errors that occur during signal transmission or interpretation (artifacting).”
