Testing system for vacuum ultraviolet fluorescence spectrum radiation in plasma display panel

A testing system for Vacuum Ultraviolet (VUV) fluorescence spectrum radiation in Plasma Display Panel (PDP) is designed for testing and evaluating the properties of PDP phosphor. Through an ingeniously designed test chamber and simulating the PDP discharge unit, it will provide a stronger vacuum ultraviolet needed for exciting PDP phosphors. When PDP phosphor is excited, the system can analyze the phosphors and obtain various optical features such as spectral power distribution, luminous brightness, bandwidth, peak wavelength of the emitting spectrum, color coordinate, color purity and dominant wavelength. The experimental data show that the system has a good testing repeatability and high-accuracy, this provides a basis for developing a high-quality plasma display panel.
