Understanding OLED Screens
An OLED screen, or Organic Light Emitting Diodes Screen, is a type of organic LED. This LED has a phosphorescent organic layer that emits light when current flows through it. It leverages the light-emitting mechanism of LEDs to display light.
The Structure of OLED Screens
An OLED screen consists of four components with different functions, namely:
- Anode: a bottom space, responsible for holding positive charge when current flows through the screen.
- Cathode: a top space, responsible for holding negative charge when current appears. This component functions opposite to Anode.
- Organic conductor layer: the layer between the two Anode and Cathode poles. This layer has two main parts, including the conductive layer (constructed from flexible organic molecules to transport 'electron holes' from Anode) and the light-emitting layer (transporting electrons from Cathode).
- Substrate: serves to support the aforementioned components and is typically made of plastic or glass.
Pros and Cons of OLED Screens
Compared to some products using LCD, AMOLED technology, OLED technology has its own pros and cons. Let's examine the following pros and cons to make a decision on whether to choose this technology product or not?
Most Outstanding Advantages of OLED Screens
Offering better image quality, with higher contrast and brightness. Consequently, this screen provides deeper black levels, more accurate colors, and higher contrast ratios. Especially, the color of pixels remains unchanged even when the viewing angle reaches 90% compared to normal.
Lighter and more flexible structure: as it does not use backlight to emit light but directly emits light from LED diodes. Eliminating the backlight makes the screen lighter when there are no unnecessary substrates. Additionally, this screen is made of plastic, thus having better resistance to breakage (compared to LCD glass screens).
Outstanding Advantages of OLED TechnologyFaster response time: According to LG, the response time of OLED screens is up to 1000 times faster than LCD. As a result, you will experience more lifelike viewing on this screen.
Energy saving: With an automatic emission mechanism based on organic light-emitting diodes, it provides higher energy efficiency compared to some other screens.
More energy-efficient and faster responseDrawbacks of Using OLED Screens
The lifespan of OLED screens is determined by the lifespan of organic materials. According to a 2008 technical report, blue OLED TVs have a lifespan of about 14,000 hours with half brightness reduction (after 5 years of use averaging 8 hours/day).
This lifespan figure is much lower compared to conventional screens using LCD or LED technology. Additionally, the lifespan of the screen further decreases in low humidity conditions.

Devices Utilizing OLED Screens Popular Today
With the benefits it brings, OLED is widely applied in many fields, especially in the electrical and electronic industry. Consequently, there are a plethora of computer monitors, TVs, phones, and other devices using this screen.
OLED Computer Monitors and OLED Laptops
The two most prominent brands specializing in OLED computer monitors are Dell and LG. These companies offer various monitor models with different sizes and prices. In addition to providing displays for PCs, they also produce laptops equipped with OLED technology. These products are favored by many consumers for their excellent display quality.
Computers and laptops are devices that utilize OLED technologyOLED Screens on Android and iPhone
Apart from computers, phones are also one of the most widely used devices employing OLED technology. OLED phone screens, particularly those from Samsung, are easily accessible. Specifically, these screens are found on models such as the S8 Plus, Note 8, and Galaxy S8.
Moreover, Apple has begun implementing OLED technology for its iPhone product lines, notably the iPhone X. Additionally, other companies like Google, OnePlus, Lenovo, etc., also offer products featuring this screen technology.
Many iPhone and Android phone brands utilize OLED technologyLarge OLED TVs from LG and Sony
OLED screens are best suited for TVs as they offer a wide color gamut and true-to-life colors. Many TVs feature this type of screen, with LG and Sony leading the way in OLED technology adoption.
For LG, you can find OLED TV models such as the LG OLED Evo 55C2PSA, LG OLED Gaming 4K 42 inch 42C2PSA, and LG Smart OLED 4K 97 inch 97G2PSA.
Numerous LG TV models utilize OLED technologyFor Sony, you can consider OLED TV models like the Sony 4K 55 inch XR-55A80K, Sony 4K 48 inch XR-48A90K, and Sony 4K 55 inch KD-55A8H.
