P‐50: Principle and Improvement of Shaking Stripe

Abstract

Shaking Stripe is a complicated issue in TFT-LCD which has a significant impact on product development because of the lack of design rules. According to this article, the phenomenon is systematically described from two dimensions including spatial frequency and time frequency. Then, it is demonstrated that the different brightness of pixels in a same frame is the immediate reason for this issue, which cannot be homogenized by human eyes. The phenomenon will be more obvious when the difference comes to six gray levels for the gray picture of L127. Furthermore, we investigate three design rules in TN product with the design of Dual Gate and Z-inversion which has a high risk in this issue.
