Comparing OLED and LCD Screens: A Definitive Guide

Posted by Repair Media on

What are OLED and LCD Screens?

OLED (Organic Light Emitting Diode) and LCD (Liquid Crystal Display) are two popular types of display technologies used in electronic devices such as smartphones, televisions, and computer monitors. Both technologies have their own unique characteristics and advantages.

How do OLED Screens Work?

OLED screens are made up of organic compounds that emit light when an electric current is applied. Each pixel in an OLED display is self-emitting, meaning it can produce its own light. This allows for deep blacks, high contrast ratios, and vibrant colours. OLED screens also have faster response times and wider viewing angles compared to LCD screens.

How do LCD Screens Work?

LCD screens, on the other hand, use a backlighting system to illuminate the pixels. The liquid crystals in an LCD panel act as shutters, allowing or blocking the light from the backlight to create the desired image. LCD screens can produce bright and sharp images, but they may struggle with achieving true blacks and have limited viewing angles.

Image Quality

When it comes to image quality, OLED screens generally outperform LCD screens. The self-emitting pixels in OLED displays result in deeper blacks, higher contrast ratios, and more vibrant colours. LCD screens, although capable of producing bright and sharp images, may struggle with reproducing true blacks.

Power Consumption

OLED screens are known for their energy efficiency. Since each pixel in an OLED display emits its own light, it can be individually turned off when displaying black or dark content, resulting in lower power consumption. LCD screens, on the other hand, require a constant backlight, which consumes more power regardless of the content being displayed.

Screen Lifespan

One factor to consider is the lifespan of the screens. OLED screens have organic compounds that can degrade over time, leading to potential issues such as burn-in. LCD screens, on the other hand, do not suffer from burn-in and generally have a longer lifespan. However, advancements in OLED technology have significantly improved its lifespan in recent years.


When it comes to price, LCD screens are generally more affordable compared to OLED screens. The manufacturing process for OLED displays is more complex and expensive, which reflects in the final product price. However, as technology advances and economies of scale come into play, the price gap between the two technologies is gradually narrowing.


In conclusion, OLED and LCD screens have their own strengths and weaknesses. OLED screens offer superior image quality, energy efficiency, and wider viewing angles. LCD screens, on the other hand, are more affordable and have a longer lifespan. When choosing between the two, it ultimately depends on your specific needs and budget. Consider factors such as image quality, power consumption, screen lifespan, and price to make an informed decision.
