P‐50: Dynamic Gamma: Applications to Improve LCD Temporal Response using Overdrive

In our previous papers, we proposed a metric “dynamic gamma” to quantitatively evaluate the dynamic temporal response of an LC display device. Dynamic gamma, associated with 2-D plots, is arguably more suitable for quantitatively characterizing the dynamic characteristics of an LC panel. In this paper, we apply the dynamic gamma metric to improve the temporal response of LCD. From dynamic gamma data, overdrive table can be derived. It can also evaluate the quality of overdrive. With the second order dynamic, we can even assess the performance of different overdrive algorithms. Test result confirms that dynamic gamma is not only a good metric for LCD panel, but also for overdrive algorithm evaluation.
