通过改变对比度和亮度水平来研究彩色液晶显示器的图像质量。分辨率通过调制传递函数面积 (MTFA) 进行评估，该面积是在九种不同的亮度和对比度组合下测量的。在这些组合中，我们测量红-绿-蓝通道的色度坐标和亮度作为数模转换值的函数。我们分析了白色图案的 MTFA 值、恒定通道色度、色域和最大亮度之间的关系。从结果来看，发现级别的组合可提供高分辨率和良好的色彩再现。
The image quality of a color liquid-crystal display monitor is studied by changing the contrast and the luminance levels. The resolution is assessed with modulation transfer function area (MTFA) that is measured at nine different combinations of the luminance and contrast. At these combinations, we measure the chromaticity coordinates and luminance of red-green-blue channels as a function of the digital-analog convert value. We analyze the relations among MTFA value, constant-channel chromaticity, color gamut, and maximum luminance of a white pattern. From the results, the combination of levels is found that provides both high resolution and good color reproduction.
