Advantages of OLED:
- True Black Representation:
- LCD has a flaw where the liquid crystal layer cannot fully close, resulting in a grayish color when displaying black. OLED, on the other hand, achieves genuine black.
- No Light Leakage:
- LCDs have a backlight layer, and light can escape through gaps between the screen and the frame, causing light leakage.
- Slim Design:
- OLED screens are significantly thinner compared to LCD screens due to the absence of a backlight layer and liquid crystal layer.
- Flexibility:
- OLED screens can be curved to a greater extent as they lack the rigid backlight and liquid crystal layers. Hence, most curved smartphone screens in the market are OLED.
- Vivid Colors:
- Higher contrast ratios in OLED result in clearer, more vibrant images with bright and vivid colors.
- Individual Pixel Illumination:
- OLED allows for individual pixels to emit light in specific areas, enabling features like always-on display for showing time even when the screen is locked.
- Low Power Consumption:
- OLED pixels light up or turn off independently, consuming less power compared to LCD, where all pixels are constantly active.
- Fast Screen Response Time:
- OLED pixels transition between colors rapidly, resulting in a short response time and minimal motion blur, providing a better visual experience compared to LCD.
Disadvantages of OLED:
- Screen Lifespan:
- OLED screens have a shorter lifespan due to the organic materials used, compared to the inorganic materials in LCD.
- Screen Flicker:
- OLED screens exhibit noticeable flickering at low brightness levels, which can cause discomfort and visual strain for some individuals.
- Burn-In:
- Over time, OLED pixels may age differently due to prolonged illumination, leading to noticeable burn-in. However, maintaining brightness below 60% and avoiding prolonged display of static images can delay this effect for several years.
