How does OLED work?

OLED technology operates on the principle of electroluminescence, where the organic compounds within the display emit light when an electric current is applied to them. The functioning of OLED can be simplified into four key steps: electrical current flow, electron-hole recombination, light emission, and color filtering.

First, an electrical current is passed through a layer of organic materials called the emissive layer. This current flow is controlled by the thin-film transistor (TFT) backplane, which determines which pixels should be lit up and at what intensity. The backplane acts as a switch, allowing the electrical current to pass through specific pixels and create the desired image.

Within the emissive layer, a process called electron-hole recombination occurs. When the current reaches the layer, it causes electrons (negatively charged particles) to move from the cathode side to the anode side, while “holes” (positively charged particles) move in the opposite direction. When an electron meets a hole, they recombine, releasing energy in the form of light photons.

The light emitted from these electron-hole recombinations is what creates the pixels on the screen. Each pixel in an OLED display is made up of sub-pixels consisting of red, green, and blue (RGB) organic compounds. By varying the intensity of the electrical current flowing through each sub-pixel, the display can create a wide range of colors and shades.

Furthermore, OLED displays often incorporate a color filtering process to ensure accurate color reproduction. This involves using filters to selectively transmit or absorb specific wavelengths of light to create the desired color. By combining the RGB sub-pixels and manipulating the filters, OLED displays can reproduce a vast color gamut and achieve precise color accuracy.

Overall, the working principle of OLED technology revolves around electrical current flow, electron-hole recombination, light emission, and color filtering. These processes work together seamlessly to produce the vibrant and lifelike images that OLED displays are known for. The ability to control each pixel individually and generate true blacks sets OLED apart from other display technologies, creating a visually stunning viewing experience for the audience.
