The Significance of OLED Technology

OLED stands for Organic Light Emitting Diode and is a type of display technology that makes it possible to reach the dark black levels from the ultra-thin screens while making displays more efficient and eco-friendly.

 How Does OLED Technology Work?

An organic, carbon-based film remains in between two conductors and when the electric current is passed through, it emits light. This place occurs in every single pixel in an OLED display.

OLED display differs from an LCD (Liquid Crystal Display) panel that requires a backlight – which is made of standard LEDs) for lighting up the liquid crystals and create a better quality images. This requires an ample amount of energy and you can’t get true blacks as the backlight affects the neighboring pixels.

Using an OLED panel, the organic pixels become self-emissive that means they generate their own light. Therefore, it can become pitch-black when turned off.

 Types

There are actually two different types of OLED technology – Active-Matrix (AMOLED) and Passive-Matrix (PMOLED). Active-Matrix needs electronics every pixel on or off individually. It’s ideal for displaying deep blacks and can be used in OLED TVs available today.

OLED features an additional white pixel along with the usual red, green, and blue sub-pixels. It aims to deliver different and accurate colors while increasing the lifespan of the display.

 OLED VS LCD – Which is Better?

·         OLED has plastic, organic layers that are lighter, thinner, and more flexible than the crystalline layers of LCD.

Though the light emitting layers of an OLED are lighter. Its substrate can be flexible instead of being rigid.The OLED substrates can be plastic while LCDs use glass substrates.

OLED has brighter displays than LCDs. The organic layers of an OLED are much thinner than the inorganic crystal layers of an LCD. In fact, the emissive and conductive layers of OLED can be multi-layered. Both LEDs and LCDs need glass for support and obviously glass absorbs some light while OLED don’t need glass.

OLED doesn’t require backlighting like LCDs. Usually, LCDs work by blocking areas of the backlight to create the images that you see while OLEDs generate light themselves. Though OLEDs don’t need backlighting, they consume much less power than LCDs. It’s important for batter-operated devices like cell phones.

OLED display modules are easy to produce and can be made to larger sizes. OLEDs can be made into large, thin sheets. It’s difficult to grow and lay down many liquid crystals.

 OLEDs offer large fields of view, around 170 degrees. LCDs work by blocking light and have inherent viewing obstacle from specific angles. They produce their own light and have a much wider viewing range.
