Digital pathology (DP) has transformed the practice of pathology by digitizing pathology glass slides, thereby enhancing diagnostic capabilities. In contrast to radiology, studies comparing the efficiency of DP monitors are limited. This work used a stress test that simulated DP sign-out in practice to evaluate the performance of medical-grade (MG) and consumer off-the-shelf (COTS) displays. Four displays, including three MG and one COTS, were assessed for luminance, contrast ratio, accuracy, and image uniformity. Key metrics, such as luminance uniformity and maximum brightness, were evaluated during a 1-month period that simulated use to reflect an 8-h work day. MG displays outperformed COTS in critical parameters, even though consumer displays were satisfactory for diagnostic purposes. Image uniformity exhibited the most significant variations, with deterioration noted over 2.5% for all displays during the test period. This study compared different types of displays for DP and highlights the importance of regular calibration for maintaining display performance when using DP. Further research is recommended to define validation protocols, including the impact of display aging on DP accuracy.
数字病理学（DP）通过将病理玻片数字化改变了病理学实践，从而提高了诊断能力。与放射学不同，比较DP显示器效率的研究有限。这项工作使用了一种压力测试，模拟实际中的DP签出流程，以评估医用级（MG）和消费级现货（COTS）显示器的性能。对包括三台MG显示器和一台COTS显示器在内的四台显示器进行了亮度、对比度、准确性和图像均匀性评估。在模拟使用以反映8小时工作日的1个月期间，对亮度均匀性和最大亮度等关键指标进行了评估。尽管消费级显示器对于诊断目的而言令人满意，但MG显示器在关键参数方面表现优于COTS显示器。图像均匀性表现出最显著的变化，在测试期间所有显示器的图像均匀性恶化均超过2.5%。本研究比较了用于DP的不同类型显示器，并强调了在使用DP时定期校准以维持显示器性能的重要性。建议进一步开展研究以定义验证方案，包括显示器老化对DP准确性的影响。
