What Is Stacked OLED?
As the demand for electronic products continues to grow, advances in display technology are driving constant innovation. Stacked OLED (Organic Light Emitting Diode) has emerged as an innovative display technology with great potential in improving image quality, brightness, and efficiency. Particularly in the fields of smartphones, televisions, and wearable devices, stacked OLED is becoming the mainstream choice for high-end displays. This article will explore the definition, working principles, features, advantages, and applications of stacked OLED technology.
I. What is Stacked OLED?
Stacked OLED is a display technology that stacks multiple OLED layers vertically to enhance display performance. The core idea behind this structure is to use multiple emitting layers within a single display panel, with each layer having its own independent current-driving circuit. This allows for improved brightness and display quality without increasing the thickness of the panel. Stacked OLED represents a significant breakthrough in OLED technology, offering improved efficiency and image quality.
II. Working Principles
The working principle of stacked OLED is similar to traditional OLED but achieves performance improvements by stacking multiple emitting layers. In traditional OLED, each pixel consists of a single organic light-emitting material layer. In stacked OLED, several layers of organic materials are added and arranged vertically. Each OLED layer is responsible for outputting different colors or brightness levels, and through precise control of current and voltage, the layers work together seamlessly.
Special conductive layers separate each stacked layer, ensuring uniform current distribution and preventing display distortion caused by uneven currents. Additionally, stacked OLED optimizes materials and packaging technologies to ensure each layer operates stably under the same temperature and current conditions, preventing heat damage and brightness degradation.
