Posted on: August 17, 2022

What Is an OLED Display?

An OLED (organic light-emitting diodes) display produces an array of OLED pixels that emit light when current is passed through them. This makes OLED displays thinner and more efficient, compared to traditional LCD displays. Additionally, OLED displays can be made transparent, flexible, foldable, and even rollable and stretchable in the future.

What Is an AMOLED Display?

An AMOLED (active-matrix organic light-emitting diode) is a display technology used in smartwatches, mobile devices, laptops, and televisions. AMOLED displays are made by placing a grid of thin-film transistors (TFTs) on top of an OLED film. AMOLED displays are typically brighter and contrast better than LCDs. They also consume less power, which can help to extend their battery life.

Difference Between AMOLED and OLED Displays

AMOLED vs OLED Displays

OLED and AMOLED displays are very similar, but there are a few key differences.

  • Technology Used:

    The fundamental structure of OLED and AMOLED is different. OLED has numerous thin layers of organic compounds, whereas AMOLED includes a thin layer of transistors on top of the layers of organic compounds. OLEDs display an image by using thin-film organic light-emitting diodes, while AMOLED displays use an extra active-matrix layer to control the current running through each pixel.

  • Power Consumption:

    AMOLED displays typically consume less power than OLED displays. This is due to the fact that each pixel in an AMOLED has its own transistor and capacitor, allowing for more efficient power usage. By using an AMOLED, the user saves money on device operating costs.

  • Display:

    Unlike LCD panels which have a backlight that is always on, OLED displays are “off” by default unless each pixel is electrified. This enables much deeper blacks. AMOLED displays do not perform as well in direct sunlight when compared to other types of displays. The exceptional picture quality of AMOLED displays is due to the TFT backplane technology.

  • Contrast Ratio:

    The contrast ratio of an OLED display is excellent since it has a high degree of pixel control. AMOLEDs have faster refresh rates than regular OLEDs, providing a great artificial contrast ratio. This is because each pixel on an AMOLED display emits light, resulting in a crisper image.

  • Sunlight Readability:

    AMOLED displays cannot be read as quickly in direct sunlight when compared to LCDs and OLEDs.

  • Viewing Angle:

    The viewing angle of an AMOLED display is slightly better than that of an OLED display.

  • Display Size:

    Both OLED and AMOLED provide more efficient and bright displays as these are comparatively thinner compared to the LCDs. AMOLED displays are not restricted to certain display sizes like OLEDs, so they can be fitted into any size. AMOLED panels, on the other hand, can support any display size and can produce a faster refresh rate even at a large size.

  • Display Cost:

    AMOLED displays are more expensive to manufacture compared to OLED displays.

  • Water Resistance:

    OLED panels are more water resistant since there is no risk of damaging the backlight.

  • Eye Safety:

    Because OLED panels do not use a backlight, they are considered to be safer for your eyes compared to AMOLEDs.

Which Display Is Better for You?

Now that we know the key differences between OLED and AMOLED displays, it’s time to decide which one is better for you.

While both OLED and AMOLED technologies have many similarities, AMOLED has several significant advantages over its OLED counterpart. Many of the top smartphone companies use AMOLEDs in their products because they are more flexible than other types of OLED devices. While AMOLED devices cost more to produce than OLED displays, but the image quality is generally better, and they consume less power.

That said, if you’re looking to buy a monitor that will last you longer, an OLED display would be a better choice since it won’t wear down as quickly.

Both OLED and AMOLED displays have their unique advantages and disadvantages. It really depends on your needs as to which display is better for you.

Optical Bonding Options for Rugged Touchscreen LCD Displays

Posted on: August 10, 2022

Digital SignageTouchscreen displays are becoming more and more common in both personal and business settings. They offer a level of convenience and interactivity that is hard to beat. However, touchscreen displays can be fragile and are susceptible to damage from drops or scratches.

One way to protect against this type of damage is to use an optical bonding process to attach the touchscreen LCD to a protective glass panel. This article will explore the different options for optical bonding and discuss the benefits and drawbacks of each option.

What Is LCD Optical Bonding?

LCD optical bonding is a process in which the LCD and a protective glass panel are bonded together using an optically clear adhesive. This process can be used to protect the LCD display from damage due to drops, scratches, or other types of impacts. 

When a regular display is utilized in an outdoor setting, several variables influence its readability. The most typical is condensation, or fog, which forms on the inner surface of the display’s shield. The reflection of sunlight also plays a factor, often resulting in a mirror image on the display. However, both these problems can be eliminated by using optical bonding.

Types of Optical Bonding

There are a few different types of optical bonding for LCD displays, including:

  • Optical Clear Adhesive (OCA) Lamination:

    Optical clear adhesive is a type of UV-curable glue that is used to bond the LCD and the glass panel together. Once the adhesive cures, it is optically clear and allows light to pass through it without distortion. This type of optical bonding is typically used in displays that will be exposed to harsh environments, as it provides the highest level of protection against damage.

  • Air Gap Bonding:

    The air gap filling or bonding process is accomplished by first cleaning the inside surfaces of the LCD and the glass panel. A UV-curable adhesive is then dispensed onto one of the surfaces, and the two surfaces are brought together. The adhesive is cured using UV light, and the air gap is filled with an optically clear resin. This type of optical bonding provides a medium level of protection against damage.

  • Liquid Optical Bonding:

    The liquid bonding process is similar to the air gap bonding process, but instead of using a UV-curable adhesive, a liquid optically clear adhesive is used. This adhesive is dispensed onto one of the surfaces, and the two surfaces are brought together. The adhesive cures over time, and the liquid optically clear adhesive helps to fill any air gaps. This type of optical bonding provides a lower level of protection against damage, as the liquid adhesive is not as durable as a UV-curable adhesive.

  • Optical Clear Film Lamination:

    Optical clear film lamination is a process in which an optically clear film is used to bond the LCD and the glass panel together. This type of optical bonding provides a medium level of protection against damage, as the optically clear film helps to absorb shock.

  • Liquid Optical Clear Adhesive (LOCA) Bonding:

    The LOCA bonding process is similar to the liquid bonding process, but instead of using a liquid optically clear adhesive, a UV-curable adhesive is used. LOCA is utilized in touch panels and display devices.

  • Dry Optical Bonding:

    Dry Optical Bonding uses heat and pressure to attach the touch panel directly to the LCD. This process makes for a more durable and scratch-resistant product. However, it is important to note that this type of optical bonding can only be done if the materials being bonded have a similar coefficient of thermal expansion.

Which Industries Is Optical Bonding Best Suited?

Optical bonding is suitable for a wide range of industries, including:

Advantages of Optical Bonding for Touchscreen LCD Displays

There are many advantages to using optical bonding, including:

  • Improved durability
  • Improved readability
  • Reduced reflection
  • Reduced condensation
  • Increased sunlight-readable display performance
  • Improved touchscreen sensitivity
  • Protection from environmental damage
  • Increased contrast ratio
