QLEDnäyttöinä

QLEDnäyttöinä (Finnish for QLED displays) refers to televisions and other display devices that utilize Quantum Dot Light Emitting Diode technology. Quantum dots are microscopic semiconductor particles that emit different colors of light when energized. In a QLED display, these quantum dots are placed in a layer between the LED backlight and the LCD panel.

When the LED backlight illuminates the quantum dot layer, the dots absorb this light and re-emit it at very specific wavelengths. By using different sizes of quantum dots, a precise and pure spectrum of red, green, and blue light can be produced. This highly controlled light then passes through the color filters of the LCD panel, resulting in a significantly wider color gamut and brighter images compared to traditional LED-backlit LCD TVs.

The primary advantage of QLED technology is its enhanced color reproduction and brightness. This leads to more vibrant and lifelike images, with better contrast and detail, especially in brightly lit rooms. QLED displays are a form of LCD technology, meaning they still rely on a backlight and liquid crystals to create the image. They are a step up from conventional LED-LCDs in terms of color performance but are distinct from OLED (Organic Light Emitting Diode) displays, which use self-emissive pixels.
