亮室对比度是评价平板显示器视觉质量的重要参数。尤其是对于移动显示屏,亮室对比度的测定应该考虑各种光照明条件,例如应该在不同照度水平和不同光谱分布的光照下进行测定。本文介绍了首先介绍了荧光灯照明方法和球内积分球照明方法,之后详细介绍了一种新的基于球外积分球漫射照明的测试方法。此外,为了克服标准照明条件中标准光源(CIE A, D65)难以实现的难题,本文提出了光谱辐亮度系数法。
Brightroom contrast is an important parameter for evaluating the visual quality of flat panel displays. Especially for mobile displays, bright room contrast measurements should take into account a variety of lighting conditions, for example, should be measured at different illumination levels and different spectral distributions. This paper introduces the fluorescent lighting method and the ball integrating sphere illumination method first, and then introduces a new test method based on the diffuse illumination of the integrating sphere ball. In addition, in order to overcome the difficulty of standard light source (CIE A, D65) which is difficult to be achieved in the standard lighting conditions, the spectral radiance coefficient method is proposed in this paper.
