视觉研究人员依靠视觉显示技术来向人类和非人类观察者呈现刺激。期望的和显示的视觉模式沿着诸如亮度、光谱、空间和时间频率等维度匹配是开发受控实验的重要部分。随着阴极射线管（CRT）在商业市场上变得几乎不可用，确定基于有机发光二极管（OLED）面板的新可用的显示器的特性以确定它们可用于产生视觉刺激的程度是有用的。这份报告描述了一系列的测量总结了两个市售的OLED显示器上显示的图像的属性：索尼Trimaster EL BVM-F250和PVM-2541。结果表明，OLED显示器具有大的对比度，宽的色域，和精确的，良好的时间响应。正确调整两种型号的设置会产生亮度非线性，这可以通过幂函数（“伽马校正”）很好地预测。两种显示器都具有可调节的像素独立性，并且可以设置为几乎没有空间像素交互。OLED显示器似乎是许多视觉研究应用的合适甚至优选的选择。
Vision researchers rely on visual display technology for the presentation of stimuli to human and nonhuman observers. Verifying that the desired and displayed visual patterns match along dimensions such as luminance, spectrum, and spatial and temporal frequency is an essential part of developing controlled experiments. With cathode-ray tubes (CRTs) becoming virtually unavailable on the commercial market, it is useful to determine the characteristics of newly available displays based on organic light emitting diode (OLED) panels to determine how well they may serve to produce visual stimuli. This report describes a series of measurements summarizing the properties of images displayed on two commercially available OLED displays: the Sony Trimaster EL BVM-F250 and PVM-2541. The results show that the OLED displays have large contrast ratios, wide color gamuts, and precise, well-behaved temporal responses. Correct adjustment of the settings on both models produced luminance nonlinearities that were well predicted by a power function ("gamma correction"). Both displays have adjustable pixel independence and can be set to have little to no spatial pixel interactions. OLED displays appear to be a suitable, or even preferable, option for many vision research applications.
