What are the differences, advantages and disadvantages between organic light-emitting diodes (OLED) and quantum light-emitting d

What are the differences between OLED and QLED? You will usually see these two panels when shopping for a TV, this article collates the advantages and disadvantages of each and which is better for your needs!

OLED, also known as organic light-emitting diodes, has the advantages of a wide Angle of view, high contrast, low power consumption and can achieve a darker screen, he can control their specific point light source switch, but also to develop can achieve a higher contrast between light and dark display effect.

Quantum light-emitting diodes (qLED) are similar to liquid crystal displays (LCD), although the name is similar to OLED, but basically the two are completely different, you can also think of quantum light-emitting diodes as liquid crystal displays using new technology, qLED stands for quantum dot LED quantum dot displays.

QLED has the advantages of high maximum brightness, large size and cheaper than OLED. The structure of each panel is then attached to a better explanation.

OLED structure

As you can see, OLED panels can be turned on or off for specific light sources, so there's a contrast between the details of brightness and darkness, but if it stays bright for too long, it can accelerate aging and branding issues.

QLED structure

The QLED is similar to the current LCD screen, with an LED backlight as the backlight, but the LCD uses a white LED as the backlight, and the QLED is a blue LED backlight.

The difference between the two is that the traditional LCD screen uses a white LED as a backlight layer, and then allows the eye to receive a variety of different cultural colors through various layers of different social functions of the film, that is, the light will pass through these functional layers and the brightness will decrease.

QLED is to improve the traditional LCD screen, with blue LED as the backlight layer, so that blue light through the quantum dot enhanced film can get higher brightness white light, that is to say, the brightness has been greatly improved.
