A dual-cell-gap transflective liquid-crystal display (TR-LCD) with identical response time in both the transmissive and reflective regions is demonstrated. In the transmissive region, strong anchoring energy is used to decrease the response time, while in the reflective region, weak anchoring energy is used to increase the response time. And overdrive voltage technology is adopted to make the response time identical in both the transmissive and reflective regions. The device structure and operating principle of the TR-LCD was analyzed, the anchoring energy in the transmissive and reflective regions was designed, and the response time and electro-optic characteristics of the TR-LCD was calculated. The simulated dual-cell-gap TR-LCD demonstrated good performances.

The parallax images captured by a toed-in camera have positive and negative horizontal parallax for stereoscopic displays, but they also have parallax distortions including horizontal and vertical distortions. The virtual toed-in camera method can eliminate the horizontal distortion and reduce the vertical distortion. The parallax formulae for the corrected-parallax images were deduced. The experiments were carried out and the results proved that the method was accurate. Good stereoscopic images without horizontal distortion and with little vertical distortion were presented on an autostereoscopic display.

We designed an edge-lighting light guide plate (LGP) based on a micro-prism structure for liquid crystal display. Its top and bottom surfaces have micro-prisms, and a layer of high reflection film is coated on the bottom surface. The principle of the LGP was analyzed. The optical simulation tool ASAP was used to calculate the apex angle and height of the micro-prism on the top of the LGP, the apex angle of the micro-prism on the bottom of the LGP and the emitting angle dependent luminous flux of the LGP. By adjusting the width of micro-prisms on the bottom, the LGP achieved uniform luminance. A 12-in LGP based on a micro-prism structure as an example was designed. The results proved that the LGP based on a micro-prism structure is thin and simple with uniform luminance and high efficiency.

This paper proposes a method called Jump method for optimization of optical thin films. The method is the combination of local search strategy using modified Coordinate-Wise Algorithm and global search strategy using modified Evolutionary Algorithm. Jump method can evolve the designs of optical thin films for good performances. The design of a dielectric beam splitter and an edge filter as examples is carried out and the results indicate that Jump method is a very robust algorithm for optical thin film designs.

The methods of pixel arrangement for autostereoscopic liquid crystal displays based on conventional vertical parallax barriers are summarized. A novel method of pixel arrangement for autostereoscopic liquid crystal displays based on step parallax barriers is proposed. The pixel arrangements are given for different 10 inclined angles of parallax barriers and different column numbers of images. A demo of the autostereoscopic liquid crystal display using the new method of pixel arrangement presents very good stereo images. The results help to solve the process, storage and transmission of stereo images of autostereoscopic liquid crystal displays based on parallax barriers.
