Introduction of OLED displays was a revolution in the field of advanced technology and image display. It was a response to the ever-increasing needs and expectations of users, who started to notice more and more disadvantages of LCD and LED displays. OLED displays are also called organic displays. Their design is based on semiconductor technology. Among the advantages of OLED displays users include a very clear and detailed image, so it is a proposal for fans of above-average graphics and very high visual experience. OLED technology has found its application mainly in modern TV sets and computer monitors. More and more often OLED displays are offered by manufacturers of smartphones and other mobile devices. Moreover, they work perfectly well in control panels and control panels in complex systems and measuring devices. Botland offers a wide range of displays with OLED technology with different screen diagonals, resolutions and types of interfaces.

How are OLED displays constructed?
Like LED displays, OLED displays are also based on semiconductor technology. The main display layer has a thickness of 100 nm to 500 nm, which is approximately 1/200 the thickness of a human hair. Most often, OLED displays are made of 2-3 layers of organic material, in which two conductive layers are responsible for transmitting electrons from the anode to the final third layer, which emits light. The display foundation is usually made of plastics, glass and foil, and the emissive layer is made of polymers. The anode is responsible for introducing electron holes during current flow, and the cathode is responsible for introducing electrons during current flow. The conductive layer is responsible for supplying electron holes from the cathode and is made of a conductive polymer - polyaniline. The emission layer is responsible for the emission of electrons from the cathode and is made of polyfluorene and provides the target image.
How do OLED displays work?
For the OLED display to work, it must be supplied with auxiliary power from a battery or a stabilized power supply. Electric current flows from the cathode to the anode through the conductive layers. The cathode introduces electrons into the emission layer, and the anode removes electrons from the conductive layer, i.e. introduces electron holes into it. Between the emission and conduction layers, when electrons encounter an electron hole, they fill it, resulting in the release of energy in the form of photons, i.e. light particles. In this way, the emissive layer of the OLED display emits the image. The color of the glowing image depends on the quantitative chemical composition of the display layers, and its brightness depends on the power consumption, with the higher the power consumption, the brighter the display will glow. The OLED display is a high-quality screen used in many projects.
OLED display - many practical advantages and applications
The popularity of OLED displays in many consumer and professional applications is based on their many advantages. The use of plastic materials increased the durability of the displays and reduced their weight . Moreover, due to the absorption of light by the glass foundation layer in LED and LCD displays, which is not used or is added in a small amount in OLED displays, the use of plastic and polymer elements resulted in a clearer image and eliminated the need to use an auxiliary backlight , which has a positive impact on reducing energy consumption from the power source. OLED displays are also very readable over a wide range of angles between the observer's line of sight and the normal to the display surface.
OLED displays - FAQ
The OLED display is based on the technology of organic light-emitting diodes, which are a variety of conventional LEDs , but based on materials of organic origin (unlike classic semiconductors, e.g. gallium arsenide).
AMOLED displays are a variation of OLED technology that use thin-film transistors located just below the actual display panel to switch pixels. A huge advantage of AMOLED technology is the ability to achieve higher resolutions and matrix sizes compared to OLED technology with a passive matrix (PMOLED).
The number of shades that can be displayed depends on the display model. In the case of small and inexpensive displays with diagonals of 1 inch, two-color solutions (e.g. yellow and blue) are common, while full-color graphic matrices can display 16 million colors (3 x 8 bit) and even more.
An OLED screen is based on the active generation of light points through independent, miniature LED structures "sewn" in the display matrix, while color LCD screens are based on the phenomenon of light polarization and require the use of additional backlight with a special matting screen. Technological differences mean that OLED screens can achieve better contrast and higher brightness compared to LCD matrices .
