The organic light-emitting diode (OLED) is an advanced LED technology.

Organic light-emitting diodes make hydrocarbons from organic components and emit light when they get in contact with electric currents. oled panels manufacturer LEDs use backplanes to provide uniform light for all pixels.

Each pixel has an independent light source, so the image has a high contrast, and can be rendered in extremely deep black or extremely bright white.

It is for this reason that most displays, including mobile phones, flexible OLED smartwatches, TVs, desktop and laptop screens, and digital cameras, are made with OLED panels.

AMOLED (AMOLED) and PMOLED (Passive Matrix Organic Light-Emitting Semiconductor) organic light-emitting diodes are used in these devices.

The panel of the OLED screen is made up of three parts. First, the plate acts as one of the poles. The other electrode body acts as the inductive end. Between each polar body is an organic layer. In the organic layer, there are two additional layers, a light-emitting layer that creates photons and a binding layer that binds them together.

Colors of red, green, and blue are produced by combining currents and photons from different materials on the display. The black part of the display completely blocks the photons associated with the pixels.

In contrast to LED technology, this method produces a different kind of black. china oled With LED technology, a backlit panel provides a uniform light source. Although the pixels in the black part are turned off, the light source provided by the backplane is still present, so the black part that should be displayed will still glow.

OLED's advantages

OLED has the following advantages over LED:

Organic light-emitting diodes (LEDs) use less power to play the same movie than leds, which have a backplane that constantly emits light.

As each pixel light source is regulated by voltage rather than mask control, the frame rate is faster.

Due to the relatively simple internal components, the overall weight and volume are light.

There is no backplane to provide a reflecting light source to the pixels in the main part of the black screen, so the black screen shows deep and dark black. This increases color contrast.

Wide-angle images are possible with OLeds, unlike light-emitting diodes.

It has a simple internal structure, no excess laminate, and it can be curved.

OLED's drawbacks

The organic components in OLED screens cause the color to decay faster. As a result, OLED screens lose their brightness and color balance after long-term use. When blue light fades faster than red or green light, the screen quality declines dramatically.

Organic light-emitting diode screens have a higher manufacturing cost than traditional screens, and their prices are relatively high.

It is possible for both OLED and LED screens to burn, as if a specific pixel is used for too long, it will cause the screen to become branded after a while. A burning OLED screen will be more noticeable than a burning LED screen. The density of pixels in each inch also affects the burning of the screen.
