Currently, manufacturers are increasingly adopting OLED technology in their electronic devices. Compared to other technologies like LCD, Amoled, or Super Amoled, OLED technology has its own distinct advantages. But why do we often see smartphones or iPhones utilizing OLED screens more frequently? Let's delve into this article with Mytour and find out!
The trend of smartphones using OLED screens is gradually becoming widespread
Exploring OLED Technology
Unraveling OLED Technology
OLED (Organic Light Emitting Diode) technology represents a cornerstone in modern electronic devices, from smartphones to tablets and televisions. Unlike conventional displays, OLED harnesses self-emitting pixels, eliminating the need for a backlight.
Samsung integrates OLED technology in its mobile products.
Each pixel in an OLED display consists of an organic light-emitting layer sandwiched between two electrodes. When electricity passes through the display, the organic layer emits light. This technology yields superior contrast, vibrant colors, and enhanced power efficiency compared to traditional LCD screens.
Some smartphone models equipped with OLED screens include the latest iPhone model at the current moment, the iPhone 14 Series, and other models such as the Samsung S8, S8+,...
What is the structure of an OLED screen?
OLED screens are composed of various layers including: First, the electrode layer, followed by the organic light-emitting layer, and finally another electrode layer. The light-emitting material is the most crucial layer as it's where the light is generated.
The structure of the layers on OLED screens
When electric current passes through the electrodes, molecules within the luminescent material become activated. Subsequently, these molecules emit light in primary colors (red, green, and blue), forming the displayed image on the screen. Upon cessation of use, the molecules cease emitting light, and the screen automatically turns off to conserve energy.
An illustrative comparison between LG's LCD/LED technology and OLED technology
Due to the absence of a backlight like LCD panels, OLED screens are engineered to be thin, lightweight, and consume less power. Additionally, OLED technology offers superior contrast and brightness compared to LCD screens, while also providing wider viewing angles and more accurate color reproduction.
Why are modern smartphones opting for OLED displays?
Experience the brilliance of stunning image display
It is known that OLED screen designs incorporate separate color filters, resulting in deeper blacks and a wider color gamut. Unlike other technologies, OLED does not use backlighting, resulting in higher contrast. Therefore, OLED displays offer exceptional quality with sharp images and vibrant colors.
Presently, premium iPhones are equipped with OLED technology
Significantly conserve energy
One of the remarkable aspects of OLED technology is its ability to emit light without any need for electrical circuits or current flow to LED lights. Consequently, employing such screens contributes significantly to power efficiency, a prime reason why smartphone manufacturers are eager to integrate OLED technology into their mobile products to maximize battery life, thus providing users with prolonged usage.
OLED display technology contributes significantly to saving battery power in smartphones.
A prominent feature of OLED displays greatly favored by users is their wider viewing angles. This means users can view the screen from various perspectives while maintaining image quality without distortion. Viewing angles can extend up to nearly 90 degrees across various display panels.
OLED technology delivers a wider viewing angle
Moreover, OLED technology maintains better sharpness and image stability compared to traditional LED displays.
More durable and lighter
OLED panel eliminates backlight and shutter layers, replacing heavy backlight glass layers with a lighter, more durable plastic panel. Additionally, OLED film panels are curved to create a uniquely versatile device that can operate at much higher temperatures than traditional LED displays, while providing wide viewing angles and stable sharpness.
Samsung unveils bendable OLED display
Overall, OLED technology is considered the future of the smartphone market due to its standout features in delivering display excellence such as vibrant color reproduction, high contrast ratio, deep blacks,... Additionally, this panel is thinner than LCD and significantly energy-efficient.
That's why OLED screens are featured in premium smartphones, although currently they are predominantly found in high-end models like iPhone 13 Pro 512GB due to the relatively expensive manufacturing costs. Hopefully, through this article, you've gained insights into OLED technology. Stay tuned to Mytour for more updates!
