Understanding the Difference Between OLED and LCD Screens

In the aftermarket for phone screen replacements, display assemblies predominantly fall into two main categories: OLED and LCD. At NCC, we specialize in delivering high-quality, cost-effective display assembly solutions designed specifically for phone refurbishing and repair businesses.

Whether you require Incell LCD screen assemblies or advanced OLED replacements, NCC provides reliable wholesale options backed by rigorous performance testing to support your business needs.

How Display Technology Works: The Pixel Fundamentals

Before diving into the differences between OLED and LCD, it's crucial to understand how these technologies function at the pixel level.

Each display consists of millions of pixels, with each pixel comprising three subpixels—Red (R), Green (G), and Blue (B). By controlling the brightness and mix of these subpixels, a wide spectrum of colors and images can be rendered on the screen.

LCD: Backlight-Dependent Display Technology LCD (Liquid Crystal Display) screens require a white LED backlight layer. A color filter is placed over this backlight, and a liquid crystal layer acts as a valve, regulating how much light passes through each subpixel. This mechanism controls both color and brightness.

OLED: Self-Emissive Pixel Technology OLED (Organic Light-Emitting Diode) displays do not rely on backlighting. Instead, each pixel is an individual self-emissive diode that emits its own light and color. This allows OLED screens to be thinner, more flexible, and capable of delivering true blacks and superior contrast ratios.

Key Differences Between OLED and LCD Screens

Why LCD Still Holds a Strong Market Position?

Although OLED screens dominate flagship smartphones due to superior image quality, LCDs remain widely used in entry-level and budget devices for several reasons:

• Cost Efficiency: LCDs are more affordable to produce, ideal for large-scale repairs and refurbishments.

• Reduced Eye Strain: LCD displays have negligible flickering, making them better suited for extended screen time.

• Longer Durability: The inorganic materials in LCDs result in a longer functional lifespan, a significant advantage in refurbished phones.
