Abstract
AbstractTemporal characteristics are crucial factors influencing display performance. For an active‐matrix display, signals are applied sequentially line‐by‐line, and the temporal response of each horizontal line changes depending on different timings. When recording the temporal response of a display, the probe of the measuring device must have the finite size and shutter time. As the finite‐size probe records the temporal responses of multiple lines with different timings, the number of lines covered by the finite‐size probe affects the obtained result. And the effects due to the timing difference of the sequential driving can be misinterpreted as the temporal response of the display. In this study, the contribution of the various factors, such as the camera shutter time, probe size of the measuring device, temporal transition time, and display frame rate was evaluated to separate the temporal characteristics of the display from the effect caused by these factors. A procedure to estimate only the temporal response of a display without such effects is devised. The effectiveness of the proposed procedure was verified based on the spatial temporal record obtained by a high‐speed camera of video frame rates of 9000 and 12,000 per second.
