Dual-view liquid crystal display fabricated by patterned electrodes

Abstract

We design a dual-view liquid crystal display (DVLCD) which display two different images in the left and right viewing directions simultaneously. The main-pixel of the DVLCD comprises the right sub-pixels (RSPs) and the left sub-pixels (LSPs). The LCs in the RSPs and the LSPs have the opposite rotation directions, which are controlled by the inclined electric fields provided by the patterned electrodes. Addressing the RSPs and LSPs with the voltages having different polarities effectively decreases the maximum operation voltage of the DVLCD. The proposed DVLCD is free of the complicate multiple-step rubbing and shadow mask treatments, and hence has the advantages of low cost and easy fabrication.

Twisted Nematic Dual-View Liquid Crystal Display Based on Patterned Electrodes

“…The addressing principle of the patterned electrode DV LCD is explained in the previous literature. [14] Notably, in Fig. 3, the voltage difference between the electrodes on the same substrate, ex.…”

“…However, as shown in Fig. 6(a) of the ECB DV LCD, [14] a significant bright state light leakage (BSLL) appears at 70 in the un-intended viewing direction. This result indicates that ECB DV LCD can be used as a vehicle display on which the preferred viewing angles are 30 .…”

“…Recently, we have featured a DV LCD fabricated with an electrically controlled birefringence (ECB) LC cell combined with patterned electrode substrates. [14] LSP and RSP of the ECB DV LCD are discriminated by the inclined electric fields provided by the patterned electrodes. ECB DV LCD excludes the complicated two-step rubbing and the shadow mask treatments.…”

A tri-view integral imaging three-dimensional display

“…The multiple view display has been implemented by use of a lenticular lens array or a parallax barrier [2,3]. A dual-view liquid crystal display is also realized by using patterned electrodes [4]. Moreover, time-multiplexed is adopted in a blue phase liquid crystal to realize dual-view display [5].…”

“…Furthermore, the low voltage optical bounce at the unintended viewing direction as a result of LC rotation decreases the optical performance of the DV LCD. We have recently presented a DV LCD fabricated by using nematic LCs combined with the patterned electrode cell [12]. The patterned electrode structure provides an inclined electric field that defines the rotation direction of LCs in each pixel, thereby overcoming the need for the two-domain rubbing process in Chen's design.…”
