彩色等离子体显示板（PDP）是一种新型平板显示器件。发光效率是直接反映发光器件性能的重要指标。本文从理论上阐述AC型彩色PDP发光效率计算公式的物理意义，并针对器件特点，参照有关功耗和光通量的测试方法，用不同方法予以测试。分析结果表明，波形法和差值法测试功耗正确，且简便易行；测试光通量可采用光度球法和照度计法，对于亮度一致性较好的PDP，照度计法有测试数据可靠，方便简便，且仪器通用性强的优点。
Color plasma display panel (PDP) is a new type of flat panel display device. Luminous efficiency is a direct indicator of the performance of light-emitting devices an important indicator. In this paper, the physical meaning of the calculation formula of the luminous efficiency of AC-based color PDP is expatiated theoretically. In the light of the characteristics of the device, it is tested by different methods with reference to the test method of power consumption and luminous flux. The results show that the power consumption of the waveform method and the difference method are correct and easy to operate. The luminous flux can be measured by the photometric sphere method and the illuminometer method. For the PDP with good brightness uniformity, the illuminance meter method has reliable and convenient test data Simple, and the advantages of universal instrument.
