Constant humidity and heat test of flexible display devices

At present, the main technologies for realizing flexible display include organic light-emitting diode (OLED), electronic paper (e-Paper), liquid crystal display (LCD) and other technologies, as well as quantum dot light-emitting diode (QLED), Micro-LED, perovskite light-emitting display (PeLED) and other technologies.
The constant humidity and heat test of flexible display devices can evaluate the performance of flexible display devices when operating under humidity conditions. Zhongke Testing Reliability Experiment Center has the reliable performance of various flexible display devices and provides professional constant humidity and heat test services for flexible display devices.

flexible displays include flexible display modules using technologies such as liquid crystal display (LCD), electronic paper (EPD), and organic light-emitting diode display (OLED).
