OLED vs LED Backlit Screens in Laptops

OLED Display Panel Technology | LCD vs. OLED Technology | Corning


OLED Screens do not have a backlight in the same sense as a traditional LED or CCFL screen does. Traditional screens backlight the display with a Cathode ray tube or LED strip backlight that sits behind the display. OLED screens have pixels that are lit up individually. Each pixel is it's own backlight.

In the realm of laptop displays, the battle between OLED (Organic Light Emitting Diode) and LED (Light Emitting Diode) backlit screens is nothing short of a spectacle. Understanding the intricacies of these technologies can significantly influence your choice when selecting a laptop. In this article, we will delve into the backlighting mechanisms of OLED and LED screens, highlighting the key differences, advantages, and disadvantages.

  1. Backlighting Technology:

    • OLED Screens: OLED screens are a marvel of modern technology. Unlike LED backlit screens, OLED panels are self-emissive, meaning each individual pixel emits its own light. This is achieved through organic compounds that emit light when an electric current is applied. The absence of a separate backlight allows OLED displays to achieve true black levels and vibrant colours, creating stunning contrasts.

    • LED Screens: LED backlit screens, on the other hand, utilize a different approach. They employ a backlight source located behind the screen, which illuminates the pixels on the display. This backlight can be either edge-lit or directly behind the screen (full-array). LED screens often use additional layers, such as liquid crystal displays (LCDs), to modulate the light and produce the final image.

  2. Advantages of OLED Screens:

    • Perfect Blacks and Infinite Contrast: OLED screens are renowned for their ability to achieve true black levels. In areas where the image is black, the pixels simply turn off, resulting in an infinite contrast ratio. This feature enhances the overall viewing experience, especially when watching movies or playing games with dark scenes.

    • Wide Colour Gamut and Vibrancy: OLED displays have the ability to produce a wider range of colours, resulting in more vibrant and lifelike images. Each pixel emits its own light, contributing to a more accurate and dynamic colour representation.

    • Faster Response Times: OLED technology boasts faster response times compared to traditional LED screens. This can result in smoother motion handling, making OLED displays particularly appealing for gaming and multimedia consumption.

  3. Disadvantages of OLED Screens:

    • Limited Lifespan for Blue OLEDs: While OLED technology has improved significantly, the blue organic compounds in OLED screens tend to degrade faster than red and green. Manufacturers implement various technologies, such as pixel shifting, to mitigate this issue, but it remains a consideration for long-term usage.

    • Potential for Burn-In: OLED screens are susceptible to burn-in, a phenomenon where static images displayed for prolonged periods can leave a faint, persistent ghost image on the screen. However, modern OLED displays incorporate features like pixel refresh and screen savers to minimize this risk.

  4. LED Screens:

    • Cost-Effectiveness: LED backlit screens are generally more cost-effective to manufacture, making laptops with LED displays more budget-friendly.

    • Consistent Brightness: LED screens tend to maintain consistent brightness levels across the entire display, providing a reliable viewing experience.

    • Wider Range of Options: LED technology offers various configurations, such as edge-lit and full-array backlighting, providing manufacturers with flexibility in design and cost management.

  5. Conclusion:

    In the dynamic world of laptop displays, the choice between OLED and LED backlit screens ultimately depends on your priorities. OLED screens excel in providing unparalleled contrast, vibrant colours, and faster response times, while LED screens offer cost-effectiveness and consistent brightness. Consider your usage patterns, budget constraints, and personal preferences to make an informed decision that aligns with your needs. Whether you opt for the cinematic brilliance of OLED or the pragmatic reliability of LED, both technologies promise an immersive visual experience for your laptop journey.
