For years, OLED displays have been plagued by deficiencies. Samsung's QD-OLED technology addresses these issues. The following information will help you get started. Choosing a TV display technology can be a challenge if you have not already done so. There are two types of OLED and QLED displays used by Samsung and LG, the two most popular TV brands.
On the other hand, Sony will introduce a new top-of-the-line television utilizing Samsung's new quantum dot-OLED technology at CES 2022. QD-OLED technology differs from OLED and LCD TVs in several ways. What exactly does it do? Below, you'll learn all about those factors, but let's look at the current crop of TVs.
Introducing LCDs: The First Flat Screens
Despite its age, LCD technology has remained relevant since the 1960s. The first LCD TV was based upon the same principle as LED, QLED, and Mini-LED TVs. Displays like these use liquid crystal layers to control how much light reaches certain parts of the screen. A backlight (also known as a light source) is required for a clear image on the screen.

The difference between LCD, LED, QLED, and Mini-LED comes from this aspect. LEDs are increasingly being used as the backlight source for LCDs, replacing compact fluorescent lamps. In Mini-LEDs, light sources are smaller for more precise control, while QLEDs add quantum dots for improved color output.
LCD technology continues to improve
These TVs had problems that were addressed by each LCD technology development. In LCD screens, the light source is only from the top or bottom, so it comes from the edge of the screen. Moreover, they use only compact fluorescent lamps, which is a very inefficient form of lighting.
On the other hand, LED displays to provide illumination directly from behind the liquid crystal layer, allowing the entire screen to be lit. Using local dimming, the backlight in the black areas of the screen was lowered or turned off, resulting in brighter displays.
Between the backlight and the subpixel, QLED adds a quantum-dot layer. The layer shifts the frequency of the light source to transform the white backlight into either red, green, or blue. The TV produces more vibrant color output as a result.
By reducing backlight LED bulbs' size, Mini-LED improves TV contrast and allows granular dimming control. Sadly, sometimes, the LCD display TVs or monitors aren't able to properly play the 4K HDR videos, due to which OLED has a plus point over LCD. But, thankfully, Droidician has a guide on fixing 4K videos not playing issue.
TV Displays: OLED is the Gold Standard
As far as TV displays are concerned, OLED displays are the best. The reason for this is that this type of screen can deliver deeper blacks and higher contrast ratios than other types of screens.
In addition to having the best viewing angles, OLED screens also have the best contrast ratio. Users can enjoy superior image quality no matter where they are seated, including around the edges of the television. The last benefit of OLED screens is that they are much thinner than other types of screens.
A brief explanation of OLED displays
The organic light-emitting diodes (OLEDs) on these screens are activated when a current passes through them instead of a liquid crystal layer. As well as a red, green, and blue (and sometimes white) subpixel, each pixel also has a subpixel for color.
The display can control the luminance of each pixel directly to turn off the light with high precision because every pixel's luminance is directly controlled. This is why areas that appear black on the screen have no light. As a result, LCD/LED technology is unable to match the contrast ratios provided by this technology.
In addition, OLED displays require fewer layers since each pixel emits light directly, reducing the need for backlights. By doing this, the distance between the TV screen and the light source is reduced. It is possible to view from a wider angle and to make thinner forms because of these characteristics.
Compared to traditional LCDs, QD-OLEDs provide better color accuracy and a better viewing experience.
As a result of this development, OLED displays have an even better color quality than before. Moreover, it can compete with LCD/LED displays in terms of brightness while maintaining the ability to deliver true blacks that are as deep as possible.
The new OLED technology ensures HDR content can be consumed in its full glory thanks to its improved brightness and enhanced colors. By doing so, we will have the ability to view the films and videos in the way the creator wants us to.
