OLED Displays

OLED displays represent an innovative image display technology that is gaining tremendous popularity across various applications, from smartphones and portable devices to televisions and monitors. These screens are known for their exceptional image quality, making them a preferred choice for both casual users and professionals. An OLED screen is constructed using OLEDs (Organic Light Emitting Diodes), and the primary feature distinguishing it from other display technologies like LED, LCD, and PDP is that it does not require additional backlighting. This is because the diode itself emits light, rather than merely filtering white light from behind as in other technologies.

Construction of an OLED Display

OLED displays consist of pixels that contain three (red, green, blue) or four (the three mentioned earlier plus an additional white) diodes, also known as subpixels. The diode layer is applied in a process similar to inkjet printing onto a base plate. Additionally, an intermediate layer is added between the plate and emitter to enhance the efficiency and brightness of the screen.

In more detail, the individual layers are as follows:

• Substrate – transparent, usually a film or glass,
• Two conductive electrodes – a transparent anode (which must allow the emitted light to pass through), also known as the emitter, and a cathode, not necessarily transparent, also known as the conductor,
• Two organic layers – a conductive layer (organic n-type semiconductor) and an emission layer, which is an organic p-type semiconductor. This layer is responsible for emitting electromagnetic radiation in the visible spectrum of light.

OLED – A Display for Top-Notch Image Quality Enthusiasts

OLED displays guarantee the best image quality currently available. Due to their construction, they offer infinite contrast (since each pixel generates its own light), unmatched response time (the time a pixel takes to change its state – either lighting up or turning off. While other screens have a response time of 2-12 milliseconds, OLED displays only require 0.01 milliseconds). Additionally, OLED displays do not suffer from color degradation that is common in other types of screens, regardless of the angle at which the image is viewed. OLED screens also have the widest color gamut coverage, making them ideal for graphic designers. Furthermore, OLED displays are exceptionally thin, lightweight, and consume less power due to the absence of the need for additional backlighting.
