Extra info about OLED;

OLED, which stands for Organic Light Emitting Diode, is a display technology that creates images by emitting light directly from individual organic compounds. Unlike traditional LCD (Liquid Crystal Display) technology that requires a backlight, each pixel in an OLED display emits its own light, allowing for greater control over color, contrast, and energy efficiency. Here’s how OLED works:

  1. Organic Compounds: OLED displays are made up of organic compounds that emit light when an electric current passes through them. These compounds consist of carbon-based materials, which is why they are called “organic.”
  2. Pixel Structure: An OLED display is composed of millions of tiny pixels. Each pixel is made up of several layers of organic materials, including an emissive layer that emits light when stimulated.
  3. Emission of Light: When an electric current is applied to a pixel, it excites the organic materials in the emissive layer. This excitement causes the organic compounds to release energy in the form of photons, which are the particles of light.
  4. Color Creation: The colors produced by OLED displays are created by using different types of organic materials that emit light at specific wavelengths. By combining red, green, and blue (RGB) pixels, the display can create a wide range of colors.
  5. Pixel Control: One of the key advantages of OLED technology is its ability to individually control each pixel’s brightness. This enables the display to produce true blacks by simply not applying any current to a pixel, resulting in no light emission from that pixel.
  6. Thin and Flexible: OLED displays are inherently thin and flexible due to their self-emissive nature. This has led to innovations in design, including curved and foldable displays.
  7. Energy Efficiency: OLED displays are energy-efficient because they only emit light when needed. Unlike LCD displays that require a continuous backlight, OLED panels consume power only for the pixels that are active.
  8. Response Time: OLED pixels can switch on and off much faster than traditional LCD pixels. This rapid response time contributes to smoother motion and better performance, especially in applications like gaming.
  9. Challenges: Despite their benefits, OLED displays have challenges like image burn-in, where static images displayed for long periods can cause permanent damage to pixels. Manufacturers implement techniques to mitigate these issues, such as pixel shifting and brightness balancing.

In summary, OLED technology revolutionizes display technology by allowing each pixel to emit light individually, resulting in vibrant colors, true blacks, and energy efficiency. Its unique properties have led to its widespread use in modern smartphones, TVs, monitors, and other electronic devices.

Extra info about OLED common issues;

Image burn-in refers to a phenomenon that can occur on OLED panels where persistent images or patterns can become “burned” into the screen over time. This happens when a static image is displayed on the screen for an extended period, causing certain pixels to age differently than others. As a result, these pixels may degrade and become less capable of emitting light at the same intensity as surrounding pixels. The consequence of image burn-in is that the ghost or shadow of the static image remains visible on the screen, even when new content is being displayed. This is most commonly observed when elements like logos, buttons, or navigation bars are consistently present on the screen, such as with video game HUDs or news tickers.

OLED panels are particularly susceptible to burn-in compared to other display technologies like LCD, because each pixel in an OLED panel emits its own light and deteriorates over time. Manufacturers employ various techniques to mitigate the risk of burn-in, including pixel shifting and screen savers, but the potential for burn-in remains a concern for devices with OLED screens.

It’s worth noting that modern OLED panels and devices often incorporate technologies and strategies to reduce the likelihood of burn-in, and most users won’t experience significant issues under normal usage patterns. However, image burn-in can still occur if static images are displayed for prolonged periods, especially at high brightness levels.

Vertical banding is a visual artifact that can occur on OLED displays. It refers to the appearance of faint, often subtle, vertical lines or bands on the screen that can be seen during certain display conditions, particularly when showing uniform colors or gradients. These bands may appear slightly darker or lighter than the surrounding areas and can create an uneven or non-uniform appearance on the screen.

The bands typically run from the top to the bottom of the display and can be more noticeable on certain colors or shades. The issue is more pronounced in some OLED panels than others due to manufacturing variations. Vertical banding is a type of non-uniformity issue that can be caused by variations in the OLED material properties or in the manufacturing process. It can be more apparent on certain brightness levels, viewing angles, or content types.
