New fast response in‐plane switching liquid crystal mode

Abstract

This study aims to develop a novel in‐plane switching liquid crystal display with a fast response time, known as short‐range lurch control in‐plane switching (SLC‐IPS) mode. We found that the distance l, which is orthogonal to the liquid crystal layer thickness, affects the response properties of the liquid crystal display mode. The distance l was obtained using a simple electrode structure. The SLC‐IPS obtained by this structure exhibits a response that is approximately three times faster than that of a conventional IPS. We applied the SLC‐IPS to virtual reality head‐mounted displays and confirmed that its response properties satisfy the requirements for moving picture quality.

“…Although the experimental results showed a deviation from both the calculated results and the predictions based on the equation reported in ref. 16, the response time decreased, as expected, as the pitch of the interdigitated electrodes was decreased. These results indicate that shorter response times can be achieved by simply using a rubbing angle of zero, without requiring additional fabrication steps or complicated drive schemes.…”

“…Notably, the electro-optical performance of the FFS cells with α = 0 exhibits trends very similar to those reported in ref. 16, which were obtained using a new IPS cell structure. The details of this new device structure have not yet been reported.…”

“…Recently, rapid growth of the digital signage and vehicular display markets has caused short response times to become an essential requirement for LCD devices to operate well under all possible ambient conditions, especially in low temperature environments. To reduce the response time of an FFS cell, various methods have been proposed678910111213141516. However, these methods all have drawbacks, such as complicated drive schemes, low transmittance, high operating voltage, and low image quality resulting from a non-uniform distribution of the residual polymer materials.…”

“…3(a) shows, the conventional FFS mode (using a positive 'H LC) has a rubbing angle T, which is typically 5q ~ 10q. It has been demonstrated that the response time can be improved by setting the rubbing angle at zero [19,20,21]. Fig.…”
