Back in the days of the old arc, when televisions looked like boxes full of surprises, TVs were essentially built on the same technology: CRT. These were rudimentary times, when much was still analog, but it was certainly an important step to get to where we are today.

It was not until the turn of the century that Liquid Crystal Display (LCD) technology, long established in notebooks, became a trend for home screens. The revolution was surprising, as the change in pattern was impacted by both the capability of this novelty and the arrival of digital content.

However, as usual, while some manufacturers were right, others have always chosen to develop parallel technologies to pursue innovation and win over consumers with unique differentials. This was the case with Plasma technology (which for years has fought with the LCD) and the latest OLED.

This battle for the “best standard” has never been more intense than in recent years, when brands like Samsung and LG fight to get consumer attention for both quality and design. On the one hand, Samsung bets on QLED (quantum dot LEDs) technology, on the other, LG claims that OLED (organic LEDs) is unbeatable in quality.

Admittedly, OLED is a unique technology that works with OLEDs (one OLED for each pixel) that emit their own colors and lights without the need for a light source. QLED technology, on the other hand, features light-emitting LEDs that reach the quantum dots that will be displayed on the LCD panel.

The definitions already make it clear that OLED technology can be superior just by dispensing with a light source, but the fact that this change in operating mode generates a number of benefits noticeable only in these panels. Let’s see what are the advantages of OLED, which now comes as a fantastic solution, but also very expensive.

Unbeatable Contrast

As commented, OLED technology (present in televisions of brands like LG, Sony and Panasonic) has OLEDs that do not require a light source. Basically, OLEDs can control the brightness level on a scale ranging from 0% to 100% with high accuracy – and that’s true for all OLEDs with any color displayed.

This unique feature of OLED TVs allows specific pixels to be completely erased, or rather turned off. This means that if there is a particular image with many shadow areas and some are totally dark, the TV will simply erase the dots hidden by the shadow and create a composition with different levels of black color.

In practice, this brightness control implies a much better contrast level, because OLED technology reaches the maximum black level, thus reinforcing: if a pixel is off, it simply does not emit any hue. This is even more striking with the HDR image standard, which generates high dynamic contrast.

QLED and similar technologies suffer in this regard as there is an LED light source that is projected onto the panel. In this type of panel, it is impossible to reach full black level, since the LED at its minimum brightness still emits light, not to mention that other LEDs around a specific point may have some light leakage.

Tiny Response Time

Again, thinking about the root of OLED technology, we can highlight another advantage: the reduced response time in image reproduction. Basically, the range for an OLED to change its state from on to off is almost nil, so the response time is clearly shorter.

LCD panels, including QLED, require extra time to control the different playback layers and illuminate the LEDs, which may cause some delay in content display. OLED technology, on the other hand, does not need to control light separately. Its basic feature enables OLEDs to glow instantly or be deleted without any delay. Although the reduction in time is minimal, the result can be noticeable in many cases.

It’s also important not to confuse the issue of response time with input lag (which is the delay between receiving, processing and displaying the video signal), which is even more important in games when you need to have images processed in fractions. tiny seconds.

OLED may be faster in response time, but this is not true for all situations, as input lag will affect the overall user experience. Not to mention that there are numerous models of OLED and QLED, so it would take detailed analysis with comparison of various parameters to see who wins in this part of input lag.
