OLED and QLED both of them are UHD

OLED stands for “organic light-emitting diode.” In an OLED display, each pixel is made up of a thin film of organic material that emits its own light when an electrical current is applied. This means that each pixel can be turned on and off independently, resulting in deep blacks and high contrast ratios. OLED displays are also very thin and flexible, and can be bent or even rolled up.

QLED stands for “quantum dot LED.” In a QLED display, a layer of quantum dots is placed behind the LED backlight. These quantum dots emit specific colors of light when excited by the LED backlight. This results in a wider color gamut and increased brightness compared to traditional LED displays. QLED displays are also known for their high color accuracy and long-lasting performance.

In summary, OLED displays have deeper blacks and higher contrast ratios because each pixel is self-emitting, while QLED displays have wider color gamut, increased brightness and color accuracy because of the quantum dot technology.
