Introduction to OLED technology

OLED stands for Organic Light Emitting Diode. Unlike traditional LEDs that are based on silicon, OLEDs are made from organic materials. The basic principle of operation involves the recombination of electrons, similar to any LED or laser diode. In OLEDs, various materials can be used to generate different colors. Unlike TFT displays, which block light from a backlight to produce colors, OLEDs emit light themselves. This means that OLEDs don’t require a backlight, allowing them to produce true black colors and achieve high contrast ratios.

Comparison with TFT Displays

A significant difference between TFT and OLED displays is their construction. TFT displays require multiple layers, including a backlight, diffusers, polarizers, and color filters. In contrast, OLED displays have a simpler construction with fewer layers, making them thinner and potentially cheaper to produce in large quantities.

What Is An AMOLED Screen?

AMOLED screens work using organic light-emitting diodes (OLEDs), which are made from thin films of organic material that emit light when electricity is applied.

What does AMOLED mean

AMOLED stands for active-matrix organic light-emitting diode. The active-matrix design uses thin-film transistors (TFTs) to precisely control each individual pixel.

How AMOLED Works

Unlike LCD displays which require a backlight, each pixel in an AMOLED screen lights up independently. This active-matrix design means each pixel can be precisely controlled for brightness and color.

The OLED material is deposited on a substrate between two conductors – a cathode and an anode. When current flows from the cathode to the anode through the organic material, it emits light. No backlight is required, resulting in thinner, more energy-efficient displays.

Key Components

• Organic materials: OLEDs use thin films of organic compounds that emit light when electricity is applied. Common materials include polyfluorene and anthracene.
• Substrate: The OLED material is deposited on a substrate, usually glass. The substrate provides mechanical support.
• Encapsulation: OLED materials degrade quickly with exposure to air and moisture. A barrier encapsulates the OLEDs, protecting them.
• Thin-film transistors (TFTs): Each subpixel in an AMOLED screen has a TFT that controls the current flowing to it. The TFT substrate is typically silicon.
• Conductive layers: Electrodes sandwich the organic layers, providing current. A transparent anode is used on the viewing side.

AMOLED vs OLED

Is AMOLED better than OLED? The key difference between AMOLED and OLED is the incorporation of TFTs. OLED uses a simple passive-matrix structure, while AMOLED has an active-matrix of TFTs integrated into the display.

The TFT backplane in AMOLED displays provides precise control over each individual pixel. This enables higher resolution, faster refresh rates and larger panel sizes compared to passive OLEDs.

AMOLED’s active-matrix design avoids issues with crosstalk or ghosting, providing sharper, higher-quality imaging. The fast refresh rates also make AMOLED well-suited for video applications.

AMOLED Display Benefits

What makes AMOLED so appealing for smartphones, televisions, and industrial uses? Here are some of the key advantages of AMOLED technology:

Vibrant Colors and Contrast

AMOLED displays can reproduce incredibly rich, saturated colors and deep blacks. With no backlight, pixels can be fully switched off to produce perfect black. The contrast ratio can be 100,000:1 or higher.

This vibrant contrast makes images and video really pop. It’s ideal for entertainment applications and can also provide crisp, readable text and graphics for industrial HMIs and displays.

Better Viewing Angles

As each pixel emits its own light, the viewing angle is far wider on AMOLED screens compared to LCDs. Colors and brightness remain consistent even at wide angles of up to 160 degrees.

This allows flexibility in mounting AMOLED displays and makes them well-suited for collaborative applications where content needs to be viewed from various angles.

Faster Refresh Rates

AMOLED’s response time is extremely fast, with refresh rates reaching 120Hz or higher. This enables smooth, sharp motion for video, animation, and gaming uses.

The fast response also allows for touch sampling rates up to 240Hz, meaning smoother and more responsive touch interactions. This is advantageous for industrial touchscreens and HMIs.

Display technology for use in mobile devices and televisions

AMOLED (active-matrix organic light-emitting diode; ) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.

Since , AMOLED technology has been used among mobile phones, media players, TVs and digital cameras,[1] and the current progress over this technology is in lower power usage, lower cost, better resolution and specifically for larger screen (e.g. 8k screens).[2][3][4]

Design

[edit]

An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.[5]

Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for passive-matrix OLED operation.[6]

TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies, polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays.[7]

History

[edit]

AMOLED display research was initiated by Steven Van Slyke and Ching Wan Tang, who pioneered the organic light-emitting diode (OLED) technology at Eastman Kodak Co. in .[8] The first AMOLED displays were introduced in the early s, with Samsung being the first company to commercialize AMOLED displays. One of the earliest consumer electronics products with an AMOLED display was the mobile handset, BenQ-Siemens S88. [9]In , the iriver Clix 2 portable media player.[10] In it appeared on the Nokia N85 followed by the Samsung i - both Nokia and Samsung Electronics were early adopters of this technology on their smartphones.[11]

Future development

[edit]

Manufacturers have developed in-cell touch panels, integrating the production of capacitive sensor arrays in the AMOLED module fabrication process. Researchers at DuPont used computational fluid dynamics (CFD) software to optimize coating processes for a new solution-coated AMOLED display technology that is competitive in cost and performance with existing chemical vapor deposition (CVD) technology. Using custom modeling and analytic approaches, Samsung has developed short and long-range film-thickness control and uniformity that is commercially viable at large glass sizes.[12]

Comparison to other display technologies

[edit]

AMOLED displays are proved to be better at providing higher refresh rates than those of passive-matrix,[13][14]often have response times less than a millisecond,[15] and they consume significantly less power.[16] This advantage makes active-matrix OLEDs well-suited for portable electronics due to its high productivity for everyday use. AMOLED also stands higher in the field of less power consumer than OLED, because "each pixel have their own light and can be controlled leading to better power control and amplification", where power consumption is critical to battery life.[17]

The amount of power the display consumes varies significantly depending on the color and brightness shown. As an example, one old OLED display consumes 0.3 watts while showing white text on a black background, but more than 0.7 watts showing black text on a white background, while an LCD may consume only a constant 0.35 watts regardless of what is being shown on screen. A new FHD+ or WQHD+ display will consume much more.[18] Because the black pixels turn completely off, AMOLED also has contrast ratios that are significantly higher than LCDs.[19]

AMOLED displays are often difficult to see in direct sunlight compared with LCDs because of their reduced maximum brightness.[20]Super AMOLED, a modern technology, addresses this issue by reducing the size of gaps between layers of the screen.[21][22] Additionally, PenTile technology is often used for a higher resolution display while requiring fewer subpixels than needed otherwise, sometimes resulting in a display less sharp and more grainy than a non-PenTile display with the same resolution.[23] The organic materials used in AMOLED displays are very prone to degradation over a relatively short period of time, resulting in color shifts as one color fades faster than another, image persistence, or burn-in.[24][25]

Marketing terms

[edit]

Super AMOLED

[edit]

Super AMOLED is a marketing term created by Samsung for an AMOLED display with an integrated touch screen digitizer, the layer that detects touch is integrated into the display, rather than overlaid on top of it and cannot be separated from the display itself. When compared with a regular LCD display an AMOLED display consumes less power, provides more vivid picture quality, and renders faster motion response as compared to other display technologies such as LCD.[26] However, Such type of AMOLED is even better at this with 20% brighter screen, 20% lower power consumption and 80% less sunlight reflection. According to the Samsung, Super AMOLED reflects one-fifth as much sunlight as the first generation AMOLED.[27][28] The generic term for this technology is One Glass Solution (OGS), a touchscreen technology that combines the touch sensor and cover glass into a single layer, reducing overall thickness and improving optical clarity. This is achieved by coating and etching the ITO (Indium Tin Oxide) layer directly onto the cover glass, eliminating the need for a separate sensor glass and an air gap.[29]

Super AMOLED displays, while known for their vivid colors and deep blacks, also have some drawbacks, including higher manufacturing costs, potential for screen burn-in, and shorter lifespan compared to some other technologies.[30]
