As technology advances, so does the quality of the displays we use in our devices. Most of the smartphones we often see use a LCD, OLED or AMOLED display. This article delves into the specifics of LCD, OLED and AMOLED technologies, comparing their advantages and disadvantages to help you decide which might be the better option for your needs.
What is LCD Display?
LCD stands for Liquid Crystal Display. It is a common display tech seen on many electronic devices like smartphones. LCDs work by using a backlight to illuminate pixels on the screen. The backlight shines through the liquid crystals, and the arrangement of these crystals determines the amount of light that passes through each pixel, creating the images you see on the screeLCD displays are generally cheaper for smartphone companies. However, LCDs have a limited viewing angle and don’t produce true blacks because the backlight is always on. In simpler terms, even when your smartphone screen is displaying dark content, the backlight remains on, unlike OLED. This makes it less efficient in saving power compared to AMOLED displays.

What is OLED Display?
The acronym ‘OLED’ stands for Organic Light-Emitting Diode, a technology that uses LEDs where the light is produced by organic molecules. These organic LEDs are considered to be among the best display panels available today. OLEDs enable emissive displays, meaning each pixel is controlled individually and emits its own light. This results in displays with bright colors, fast motion, and very high contrast. When a pixel is off, it produces true black because no light is emitted from it.

What is AMOLED Display?
AMOLED stands for active-matrix organic light-emitting diodes. It is special for the inclusion of thin strips of thin-film transistors (TFT) behind each pixel in AMOLED displays. These transistors help electricity move more quickly across the display, allowing each pixel to be activated faster. AMOLED displays typically have faster refresh rates than other display types, making graphics smoother and more lifelike, particularly for gaming and watching movies. They also offer great viewing angles due to the TFT, enhancing the overall visibility of the image from various angles.

Conclusion
OLEDs generally consume less power than LCDs, but the AMOLED display type consumes even less power. That’s why AMOLED panels are widely used in low-power devices such as smartphones.
AMOLED has the ability to turn on or off individual pixels and switch them quickly, which enables precise and rapid control over the display’s output. The OLED panel controls a number of pixels row-wise. So, pixels for the darker content in a colorful image are off for a display of true blacks, and the brighter ones are well-lit with a great level of colour contrast.
