1. Display Structure and Basic Principles

 

Custom OLED panels operate on the self - emissive principle of organic materials. Each pixel within the panel consists of organic thin - film layers sandwiched between two electrodes. When an electric current passes through these layers, the organic materials emit light, eliminating the need for a backlight, a characteristic that sets OLEDs apart from traditional LCD panels. This self - emissive nature offers several advantages, including high contrast ratios, fast response times, and wide viewing angles.

  • Pixel Architecture: The pixel arrangement in custom OLED panels can be customized based on the application. For example, in high - resolution displays for professional graphic design, a fine - pitch pixel layout is crucial. Advanced manufacturing techniques such as shadow masking or inkjet printing are employed to ensure precise pixel placement, with a pixel pitch tolerance often controlled within ±0.003mm for high - end custom panels.
  • Substrate Selection: Custom OLED panels can utilize different substrate materials. Glass substrates are commonly chosen for applications that require high rigidity and flatness, such as large - format digital signage or industrial control panels. On the other hand, flexible plastic substrates, like polyimide, enable the creation of bendable or rollable OLED panels, opening up possibilities for wearable devices, curved displays, and flexible electronics. The choice of substrate impacts factors such as panel durability, weight, and form factor flexibility.
