OLED Displays; Lighter, Thinner, Energy-Efficient, and Offers the Best Viewing Angle than LCD Displays

OLED displays are electronic visual panels that harness organic light-emitting diodes (OLED) for their core illumination power. OLED is a type of electroluminescent display technology, in which an organic material layer generates light when molecules in the diode are agitated by an electric current. An OLED display can produce significantly high contrast levels compared to LED display. The display can control its pixels, these pixels can completely turnoff themselves whenever they are required to produce absolutely dark blacks. The acronym ‘OLED’ stands for Organic Light-Emitting Diode, a technology that uses Light-Emitting Diodes (LEDs) in which the light is produced by organic molecules. 

OLEDs are used to create digital displays in devices such as televisions, computer monitors, smartphones, and handheld game consoles. The main component in OLED displays is OLED emitter, an organic (carbon-based) material that emits light when electricity is applied. It is a display, made by placing a series of organic thin films between two conductors. Moreover, OLED displays that do not require a backlight and so are more efficient and thinner compared to LCD displays (which do require a white backlight). OLED displays provide the best image quality ever and they can also be made foldable, flexible, transparent, and even stretchable and rollable in the future. OLEDs represent the future of display technology.

OLEDs are built differently from conventional LEDs. Some displays emit light from a glass seal at the top, while others come with a substrate on the bottom. The way pixels are constructed on a large OLED display is also different from the smaller displays. Some OLED displays are made up of red, green, and blue pixels arranged side by side. Other displays use stacked pixels. The latter type allows for higher pixel density and resolution. The OLED technology has the advantages of being thin and having a higher brightness than LCDs. Its advantages over LCDs include better colour reproduction and no screen flicker. In short, it is a versatile technology, which could eventually be used in many different places. 

Global OLED displays market was valued at US$ 26.4 million in 2021 and is expected to exhibit a CAGR of 10.4 % over the forecast period 2021-2028, Says Coherent Market Insights.

If the tech is developed, it could replace LCDs. The OLED uses pulse width modulation to display colour/brightness gradations. Changing the constant power applied to OLED display results in a noticeable change in colour balance. As the brightness decreases, the colour balance changes. The screen will not flicker anymore but it will be brighter. A higher contrast will make it easier for the user to read texts and images. It is a highly flexible technology. It is also more energy-efficient than LCDs. It only needs a small amount of electricity to run. OLED displays have excellent picture quality. They have bright colors, fast motion, and most importantly, very high contrast. Most of all, real blacks are the most important.

The simple design of OLED also makes it easy to create flexible or foldable displays that can bend and move. Flexible OLED panels are manufactured on a flexible foundation made from a durable material like plastic, metal or even flexible glass. While, foldable OLED display is a developing technology, which facilitates beautiful, lighting panels, and efficient displays. They can be used in TVs and smartphones, and these are both flexible and bendable. OLED displays have improved image quality, higher brightness, better contrast, fuller viewing angle, a wider color range, and much faster refresh rates compared to LCD displays.
