An OLED display, short for Organic Light-Emitting Diode, is a cutting-edge technology that has revolutionized the way we view and interact with electronic devices. As the screen technology of choice for high-end smartphones, televisions, and wearable devices, OLED displays offer excellent image quality, vibrant colors, and remarkable flexibility. Unlike traditional LCD screens, OLEDs are composed of organic compounds that emit light when an electric current is applied, eliminating the need for a separate backlight. In this article, we will explore the structure of an OLED screen and delve into its outstanding features that have made it such a popular choice among manufacturers and consumers alike.
Different types of monitors will give you different pros and cons when using them. Let’s find out with Tnhelearning.edu.vn the screen technology on the phone today to have the best choice for your needs!
AMOLED screen
AMOLED stands for “Active Matrix Organic Light Emitting Diode”, which roughly translates as “dynamic matrix organic light-emitting diode”. This technology is one of the new screen technologies with many advantages and is expected to replace TFT screens. AMOLED screens display more vividly than TFT screens and consume less power.
Compared to TFT, AMOLED screens have clearer and more vivid color reproduction, higher definition, darker blacks (higher contrast) and wider viewing angles. In addition, AMOLED is also lighter than TFT screens, which helps reduce the weight of the phone.
But this screen also has the weakness of displaying images quite poorly in sunlight. AMOLED screens now appear on high-end smartphones from Samsung, HTC and Nokia.

IPS Quantum display (quantum IPS display)
IPS Quantum is applied by LG to the G4 super product for the first time, simply put, IPS Quantum helps to reproduce colors accurately and 25% brighter than conventional IPS screens but does not consume much battery.
This technology focuses on displaying the colors that are easiest for the human eye to grasp, red and blue, creating the best display ratio.
LED-backlit IPS LCD display
LED-backlit IPS LCD was born based on a combination of LCD, LED-Backlit and IPS panel technology. Simply put, it is a technology that uses more compressed pixels on LED-Blacklit screens and has a larger viewing angle thanks to the IPS panel. Famous representatives using this technology can be mentioned as iPad mini 1,2,3, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus…
ClearBlack Screen
This screen technology belongs to Nokia. It has the ability to combine reactions in the display and touch panels that reduce light reflections and provide much better performance when viewed outdoors.
This screen has better viewing angles and better blacks. Currently, it is widely used in Nokia Lumia devices.
IPS LCD screen
IPS monitors display images with a wider color gamut, commonly used in high-end devices, well suited for graphic design that requires a high level of display quality, in addition, IPS monitors also provide offers a viewing angle of up to 178 degrees from the horizontal, which means that users don’t have to sit directly to experience the full quality of the image.
Super LCD Display (S-LCD)
Super LCD is a special upgraded version of TFT-LCD, known as the rival of AMOLED screens, Super LCD has better contrast, more vivid colors and easy-to-see sunlight display. than AMOLED screens. However, this screen drains more battery than AMOLED screens and has lower brightness.
Super LCD screen is used quite a lot on HTC phones.
TFT-LCD . display
TFT (Thin Film Transistor) technology, which began to be introduced into smartphones in 2005, has better color reproduction and higher image resolution than previous generation LCDs. there.
As the production cost of TFT screens has dropped significantly since 2005, this display technology has become popular on basic phones and low-cost smartphones.
However, the weakness of the TFT-LCD screen is that the viewing angle is not wide. This means you have to look directly at the screen to see a clear image. Besides, the battery consumption of TFT-LCD screens is quite high when compared to recent new screen technologies.
LCD screen
LCD (Liquid Crystal Display – liquid crystal display) is a screen technology commonly used on many devices, especially phones. LCD screens do not create their own light, but rely on a backlight to glow.
The pixel density of LCD screens is very low so in sunlight colors appear very poor. The quality of LCD screens varies depending on the manufacturing process and use, most screens on low-cost phones today are made from LCD screens that provide colors and very narrow viewing angles.
LTPS LCD screen
LTPS is a technology using low-temperature polycrystalline silicon, which stands for Low Temperature Poly-silicon. This is currently one of the highest standard technologies in the display panel industry.
LTPS technology supports the LCD screen to help the phone device to be more efficient, save a lot of energy during use when the screen takes up a lot of power of the device.
Moreover, LTPS also helps devices that own it with thinner screen borders, extremely high resolution and pixel density, up to 1920 x 1080 pixels or more with a 30% wider color range than previous generations. .
TN screen
The TN screen is abbreviated as Twisted Nematic, this is a type of screen that uses a crystal structure and has been on the market for quite a while.
This type of screen has a low production cost, so it appears a lot on low-cost phone devices, or electronic devices, laptops, televisions, …
Advantages : Up to now, TN screens can be considered outdated, but there are still some advantages over popular IPS screens such as:
– Very fast response speed.
– Display images with a high refresh rate, up to 240 Hz.
– More power saving.
Cons :
– Narrow viewing angle.
– The image is easily discolored, becomes pale when not sitting opposite the screen.
PLS LCD screen
PLS screen (also known as PLS TFT or PLS LCD, full name PLS TFT LCD) is considered a rival to IPS LCD screens.
PLS is abbreviated as Plane to Line Switching, which was officially introduced at the end of 2010. This type of display is developed from the traditional TFT.
This PLS panel gives a much better display than TFT about 10% and the display quality is equivalent to IPS.
PLS is similar to IPS in that both use liquid crystals lying along the plane, but the difference is that PLS uses both vertical and horizontal electric fields to drive liquid crystals, while IPS is only a horizontal electric field. .
PLS has an affordable production cost, in addition, this type of monitor also has the advantage of displaying realistic images and a very low chromatic aberration rate.
In conclusion, an OLED display, also known as Organic Light Emitting Diode display, is a type of screen technology that has gained immense popularity in recent years. The structure of an OLED screen consists of organic compounds that emit light when an electric current is passed through them. This enables each individual pixel on the display to emit light, resulting in vibrant colors and deep blacks.
One of the outstanding features of OLED screens is their superior picture quality. The self-emissive nature of OLED allows for perfect black levels, infinite contrast ratios, and exceptional color accuracy. This results in stunning visual experiences with vibrant and lifelike images.
Additionally, OLED displays offer a faster response time, making them ideal for fast-moving content such as action-packed movies and gaming. The technology also provides a wide viewing angle, ensuring that the screen remains clear and vivid from various positions.
Furthermore, OLED screens are incredibly thin and lightweight, making them adaptable to a wide range of devices, including smartphones, tablets, televisions, and even wearable technology. The flexibility of OLED allows for curved or even rollable screens, pushing the boundaries of display design and enabling innovative form factors.
However, it is important to note that OLED displays have their limitations. They are susceptible to image retention or burn-in, especially if static images are displayed for long periods. This issue, although less prevalent in modern OLED panels, should still be considered when using the technology.
In conclusion, OLED displays revolutionize visual experiences with their exceptional picture quality, fast response times, wide viewing angles, and adaptability. As the technology continues to evolve, OLED screens are becoming increasingly popular and widely adopted in the consumer electronics industry. Undoubtedly, the future holds exciting possibilities for OLED, as it continues to push the boundaries of display technology.
