In the world of display technology, OLED panels stand as a testament to innovation, blending organic materials with semiconductor brilliance. The contrast between OLED and LED technology is well documented, yet the myriad variations of OLED—each with its unique features—remain less understood. Here, we delve into the different types of OLED panels and their distinguishing characteristics, offering a comprehensive guide to this versatile technology.
OLED Basics
At its core, an OLED (Organic Light Emitting Diode) panel consists of an electroluminescent layer made from organic compounds that emit light in response to an electric current. Unlike conventional LEDs, these organic diodes are self-emissive, producing light without the need for a backlight. This fundamental trait results in thinner, more flexible displays and the coveted "pure black" effect, where black areas of the screen are entirely off, conserving energy.
AMOLED
Active-Matrix OLED (AMOLED) displays are ubiquitous in mobile devices. These screens arrange pixels in a matrix, controlled by thin-film transistors (TFTs) that regulate current flow to each pixel. This setup allows for high-resolution, power-efficient displays that have become the standard in smartphones.
SAMOLED
Samsung’s proprietary Super AMOLED (SAMOLED) technology integrates the touch sensor directly into the screen layers, enhancing display thinness and responsiveness. Variants include Super AMOLED Advanced and Super AMOLED Plus, which offer refined pixel arrangements for improved clarity and color accuracy. The latest Dynamic AMOLED screens, featured in the Galaxy S10 series, support HDR10+ and emit less blue light.
PMOLED
Passive-Matrix OLED (PMOLED) panels are simpler and cheaper to produce but lack the resolution and efficiency of AMOLED displays. They display rows of pixels rather than individual pixels, limiting their application in high-resolution devices.
G-OLED and P-OLED
Glass OLED (G-OLED) panels typically use glass substrates, while Plastic OLED (P-OLED) panels use plastic, providing greater flexibility and durability. LG’s use of P-OLED in devices like the G Flex and V30 highlights this flexibility, making these panels ideal for wearable tech where durability is crucial.
PLED
Polymer OLED (PLED) panels, despite their similar name to P-OLED, utilize large polymer molecules rather than small organic molecules. They offer ease of adaptation and printing but are less efficient. Cambridge Display Technology and Sumitomo Chemicals hold key patents and have licensed this technology to major brands like Philips and Seiko Epson.
SmOLED
Small Molecule OLED (SmOLED) technology, developed by Ching Tang and Steven Van Slyke in 1987, uses small molecules on glass substrates. These panels, though costlier to produce, offer superior quality and are foundational to modern OLED displays.
TOLED
Transparent OLED (TOLED) panels feature a transparent layer that allows images to be displayed on both sides of the panel. With transparency rates between 70-85%, these panels are used in innovative applications like LG’s transparent TVs, offering unique visual experiences.
SOLED
Stacked OLED (SOLED) panels place red, green, and blue subpixels on top of each other, rather than side by side. This arrangement, similar to that in LCDs, can enhance color quality and brightness.
PhOLED
Phosphorescent OLED (PhOLED) technology uses phosphorescent materials to achieve up to four times the efficiency of traditional fluorescent OLEDs. Initially implemented for mobile devices, PhOLEDs are now primarily used in large-scale lighting applications.
FOLED
Flexible OLED (FOLED) panels, built on substrates that allow bending and rolling, were pioneered by Princeton University. These panels are ideal for innovative applications such as rollable TVs and flexible smartphones.
MOLED
Microcavity OLED (MOLED) technology uses dielectric and metallic mirrors to control light resonance, significantly increasing light intensity. This innovation, developed by Shizuo Tokito in 1999, enhances the brightness and efficiency of OLED panels.
UHPD OLED
Ultra High Pixel Density OLED (UHPD OLED) panels, patented by INT, offer pixel densities up to 2,228 PPI. These high-resolution displays are ideal for VR headsets, providing unparalleled visual clarity.
WOLED
White OLED (WOLED) panels generate white light using a combination of red, green, and blue emitters. LG’s WOLED technology, which includes a color filter to produce vibrant displays, is a cost-effective solution for large-screen TVs. Despite reduced brightness due to the color filter, WOLED panels remain a popular choice for high-quality displays.
QD-OLED
Quantum Dot-OLED (QD-OLED) panels, a recent innovation by Samsung, replace color filters with quantum dots, enhancing brightness and color range. These panels utilize blue light to generate other colors, promising improved performance over traditional OLEDs.
In the realm of display technology, each type of OLED panel offers unique advantages, tailored to specific applications and preferences. Whether it’s the flexibility of FOLED, the efficiency of PhOLED, or the vibrant colors of QD-OLED, OLED technology continues to evolve, shaping the future of visual displays.
