The OLED field focuses on achieving ultra-high-precision patterning over large areas, while the perovskite field is committed to translating laboratory technology into large-scale, low-cost industrial applications.
Achieve Ultra-High Precision Pixel Definition: OLED screens require the precise deposition of red, green, and blue light-emitting materials at designated positions to form pixels. This demands that coating machines solve the challenge of micron-level alignment between large-size glass substrates and Fine Metal Masks (FMM). High-end equipment achieves precise micron-level self-alignment in high-vacuum environments through high-precision alignment systems, laying the foundation for producing high-resolution screens.
Ensure Extreme Uniformity of Nanometer-Scale Film Thickness: The thickness of the OLED light-emitting layer directly determines brightness and color, requiring minimal film thickness variation across the entire glass substrate. Through innovatively designed heating mechanisms and rate control systems, coating machines solve the problem of uniformity and repeatability in large-area film formation, controlling film thickness uniformity at an extremely high level, thus ensuring consistent light emission and yield of every pixel on the screen.
Overcome Process Stability of Complex Material Systems (Co-Evaporation): To improve luminous efficiency and lifespan, OLED functional layers often require the mixing of two or more materials (co-evaporation). Through precise evaporation source designs (such as linear sources), coating machines solve the challenge of stably mixing multiple organic materials in precise proportions for long-term continuous evaporation, while preventing material decomposition and denaturation caused by prolonged high-temperature evaporation.
