等离子显示面板 第 2-6 部分：测量方法 APL 相关的伽马和颜色特性

[中文适用范围]： IEC 61988 的这一部分定义了 PDP 模块（等离子显示模块）的伽马和色域特性作为 APL 函数的测量方法。一般来说，PDP 模块的亮度水平取决于输入图像的 APL（平均图像水平）。改变输入电平会导致 RGB 原色的色度发生变化。该标准还规定了不同APL下的色调特性和色度特性的测量方法。该标准基于逆伽马电路位于模块内部的假设 [外文原描述]： IEC 61988-2-6:2015(E) defines the measuring methods for gamma and colour gamut characteristics as a function of the APL for a PDP module (plasma display module). Generally, the luminance level of a PDP module is dependent on the APL (average picture level) of input images. Varying the input levels causes a change of the chromaticity of RGB primary colours. This standard also defines the measuring methods of tone characteristics and chromaticity characteristics with varying APLs. This standard is based on the assumption that the inverse-gamma circuit is inside the module.
