The use of display devices such as smartphones, tablets, laptops is now massive and continuous in everyday life. It, therefore, becomes increasingly important to be aware of the performance of these devices, not only in terms of the tasks to be performed but also in terms of interaction with humans and therefore knows any possible effect on the ergonomics of vision. Following previous research activities conducted by the authors on the assessment of the visual ergonomics at video display terminal workstations, the aim of this study is to evaluate the ergonomics of human-system interaction of laptop displays. In details, a sample of 57 laptop displays is analyzed in accordance with the requirements of the EN ISO 9241-3xx series of international standards related to the display luminance, luminance ratio, contrast non-uniformity. An extensive luminance measurement campaign was carried out using a special pattern that allowed to measure the luminance in 13 different areas of the displays. The results obtained with this activity showed a great luminance variability between different displays. Almost all the displays are able to emit high levels of display luminance, and almost all the displays meet the requirement of contrast non-uniformity. However, several devices did not meet the recommended values of luminance ratio. Furthermore, the authors created a simplified graph to allow a rapid evaluation of the performance of the displays. This method could be periodically used in practice in order to evaluate the residual performance level.

笔记本电脑的显示器性能:符合视觉人体工程学要求的符合性评估

现在,在日常生活中,诸如智能手机,平板电脑,笔记本电脑之类的显示设备的使用非常广泛且持续不断。因此,不仅要在要执行的任务方面而且在与人的互动方面,了解这些设备的性能变得越来越重要,因此知道对视觉人体工程学的任何可能影响。在作者先前进行的有关在视频显示终端工作站上对视觉人体工程学进行评估的研究活动之后,本研究的目的是评估笔记本电脑显示器的人机交互作用的人体工程学。详细地,根据与显示器亮度,亮度比,对比度不均匀有关的国际标准EN ISO 9241-3xx系列的要求,分析了57台笔记本电脑显示器的样本。使用一种特殊的图案进行了广泛的亮度测量活动,该图案允许在显示器的13个不同区域中测量亮度。通过这种活动获得的结果显示出不同显示器之间的亮度差异很大。几乎所有的显示器都能够发出高水平的显示亮度,并且几乎所有的显示器都满足对比度不均匀的要求。但是,有些设备不符合推荐的亮度比值。此外,作者创建了一个简化的图形,以便快速评估显示器的性能。该方法可以在实践中定期使用,以评估剩余性能水平。通过这种活动获得的结果显示出不同显示器之间的亮度差异很大。几乎所有的显示器都能够发出高水平的显示亮度,并且几乎所有的显示器都满足对比度不均匀的要求。但是,有些设备不符合推荐的亮度比值。此外,作者创建了一个简化的图形,以便快速评估显示器的性能。该方法可以在实践中定期使用,以评估剩余性能水平。通过这种活动获得的结果显示出不同显示器之间的亮度差异很大。几乎所有的显示器都能够发出高水平的显示亮度,并且几乎所有的显示器都满足对比度不均匀的要求。但是,有些设备不符合推荐的亮度比值。此外,作者创建了一个简化的图形,以便快速评估显示器的性能。该方法可以在实践中定期使用,以评估剩余性能水平。某些设备不符合建议的亮度比值。此外,作者创建了一个简化的图形,以便快速评估显示器的性能。该方法可以在实践中定期使用,以评估剩余性能水平。某些设备不符合建议的亮度比值。此外,作者创建了一个简化的图形,可以快速评估显示器的性能。该方法可以在实践中定期使用,以评估剩余性能水平。
