OLED displays offer a wider range of colours, deeper blacks and brighter whites than LCD displays

OLED displays offer a range of benefits over LCD screens, including a wider range of colours, deeper blacks, and brighter whites.

OLED displays offer a wider range of colours than LCD screens. OLED screens are capable of displaying over 60 times more colours than most LCD screens. They offer a full range of colours, with true-to-life hues that pop out of the screen. OLED displays also have better colour accuracy than LCD screens, resulting in a more vibrant and lifelike picture.

OLED displays also offer deeper blacks and brighter whites than LCD screens. This is due to the different technologies used. LCD screens use a backlight, which can cause an unwanted "aura" effect, making black levels appear more like dark grey. In contrast, when black is displayed on an OLED screen, the pixels are simply turned off, providing a true black colour and an impressive contrast ratio of 1:1,000,000.

Additionally, OLED displays provide much better colour performance at low brightness levels. When the brightness is lowered on an LCD screen, the amount of light reaching the pixels is reduced, resulting in a washed-out image. On the other hand, OLED pixels produce their own light, so they can still display accurate colours even at lower brightness levels.

The superior colour performance of OLED displays results in a more immersive viewing experience, with vibrant, lifelike colours, deeper blacks, and brighter whites.

OLED displays are made up of 6 components: a substrate, an anode, organic layers, a conducting layer, an emissive layer, and a cathode

The substrate is the foundation of the OLED and can be made of plastic, glass, or metal foil. The anode, which may or may not be transparent, is positively charged and injects holes (the absence of electrons) into the organic layers. The organic layers are made of organic molecules or polymers and include the hole injection layer (HIL) and the hole transport layer (HTL). The conducting layer is made of organic plastic molecules that transport holes from the anode, and one conducting polymer used in OLEDs is polyaniline. The emissive layer is the heart of the device and where light is made. It consists of a color-defining emitter doped into a host. The cathode, which may or may not be transparent, is negatively charged and injects electrons into the organic layers.

OLEDs can have either two or three layers of organic material. In the three-layer design, the third layer helps transport electrons from the cathode to the emissive layer. The process of manufacturing OLEDs mainly involves applying the organic layers to the substrate, which can be done through vacuum deposition, organic vapor phase deposition, or inkjet printing.

OLED displays emit up to 70% less harmful blue light than LCD displays

ASUS offers a range of monitors and laptops with different display technologies, including LED and OLED. OLED displays have gained popularity in recent years and are known for their superior image quality and eye-care features.

OLED displays, such as those found in ASUS laptops and monitors, emit up to 70% less harmful blue light than standard LCD displays. Blue light is a type of high-energy visible light that can have several harmful effects on the eyes and overall health. Reducing exposure to blue light is crucial for maintaining eye health and overall well-being.

• Pixel Illumination: In an OLED display, each pixel acts as its own light source and can be turned on or off independently. This allows for true black levels and higher contrast ratios. LCD displays, on the other hand, use a backlight that illuminates all pixels simultaneously, making it difficult to achieve true blacks.
• Colour Accuracy: OLED displays offer a full range of colours with higher colour gamut coverage compared to LCD screens. This means that OLED screens can display a broader spectrum of colours with greater accuracy, reducing the need for blue light filters that can compromise colour accuracy.
• Eye Comfort: The reduced blue light emission in OLED displays contributes to eye comfort. Blue light is known to cause eye strain and visual discomfort. By emitting less blue light, OLED displays help reduce eye fatigue, especially during extended usage.
• Sleep Quality: Exposure to blue light in the evening hours can disrupt the body's circadian rhythm and negatively impact sleep quality. OLED displays, with their lower blue light emission, are less likely to interfere with your sleep schedule, making it easier to browse or watch shows before bedtime.
• Energy Efficiency: OLED displays are more energy-efficient than LCD screens. This not only improves battery life but also reduces the overall energy consumption of the device, making OLED a more environmentally friendly option.

In summary, OLED displays, such as those found in ASUS devices, offer a more eye-friendly viewing experience by emitting up to 70% less harmful blue light compared to standard LCD displays. This reduction in blue light exposure provides benefits for eye health, sleep quality, colour accuracy, and energy efficiency, contributing to a more comfortable and enjoyable viewing experience for users.

OLED displays have a faster response time than LCD displays, reducing motion blur

OLED displays offer a faster response time than LCD displays, reducing motion blur and providing a smoother viewing experience. This is because OLED displays utilise organic light-emitting diodes, where each pixel is composed of three self-illuminated sub-pixels (red, green, and blue) that are separately lit. This allows for a faster transition from one colour to another, improving the overall motion clarity of the display.

The faster response time of OLED displays offers a more fluid viewing experience, particularly for fast-paced content such as action movies, sports, and video games. The reduced motion blur results in sharper and clearer images, with less ghosting and stuttering. This is especially noticeable when compared to LCD displays with slower response times, where motion blur can be more apparent, even at higher refresh rates.

The superior motion handling of OLED displays is further enhanced by their ability to produce true-to-life colours and deeper blacks. The individual control of each sub-pixel enables OLED displays to achieve a higher contrast ratio, providing a more immersive viewing experience. Additionally, the wider colour gamut coverage of OLED displays contributes to the overall improvement in image quality.

While OLED displays excel in motion handling, it is important to consider the content being displayed. At lower frame rates, OLED displays may exhibit more noticeable stuttering due to their faster response times. In such cases, motion interpolation or black frame insertion techniques can be employed to reduce stuttering and improve the viewing experience.

ASUS, a leading technology company, has recognised the advantages of OLED displays and has incorporated them into their product lines. The ASUS Lumina OLED displays, for example, offer a 0.2 ms response time, providing exceptional motion clarity and a smoother viewing experience compared to traditional LCD displays.

OLED displays are more expensive than LCD displays

OLED displays are generally more expensive than LCD displays due to several factors, including manufacturing processes, materials used, and performance advantages.

The manufacturing process of OLED displays is more complex and involves the use of rare materials, making them harder to produce and thus, more costly. The organic materials used in OLED displays are challenging to manufacture and have a shorter lifespan than the materials used in LCD displays. This contributes to the higher price of OLED screens.

Additionally, OLED displays offer superior performance in terms of colour accuracy, deep black levels, and faster refresh rates. OLED screens can display over 60 times more colours than most LCD screens, providing true-to-life and vibrant visuals. The ability to control lighting at the pixel level in OLED displays allows for precise colour accuracy and deeper blacks, enhancing the overall viewing experience, especially in low-light conditions.

The advantages of OLED displays extend beyond just visuals. They are more energy-efficient, as they only light up the pixels needed for an image, making them more environmentally friendly and potentially extending battery life. The wider viewing angles of OLED displays also allow for a clear view of the screen from various angles, making them ideal for collaborative work or entertainment.

While LCD displays are more affordable and offer advantages in certain use cases, such as better visibility in direct sunlight and lower power consumption for brighter images, OLED displays provide a more immersive and accurate visual experience, justifying the higher price tag for many consumers.
