Enhancing the Contrast Ratio of Blue Phase LCDs
نویسندگان
چکیده
Experimental evidence proves that polymer-stabilized blue phase liquid crystal is not perfectly optically isotropic. The optical rotatory power (ORP) of double twist cylinders causes the polarization axis of the transmitted light to rotate a small angle, and leaks through the crossed polarizers. Rotating the analyzer by ~2 to correct this ORP can improve the contrast ratio by 3X. Author

P27-b: Optimization of Reflective LCDs with Phase Compensators
Using the optimization criteria, called “Polarization Transformation Efficiency” (PTE), we have obtained the optimum operating voltages that enable to realize perfect dark and bright states in RTN-LCDs with phase compensators between the polarizer and LC cell. The delicate analysis showed, that if the PTE parameter is close to 1 a 700:1 duty ratio of RSTN-LCD with phase compensators having an a...
متن کاملElectro-optics of polymer-stabilized blue phase liquid crystal displays
Electro-optics of polymer-stabilized blue phase liquid crystal displays BP LCDs is analyzed and validated experimentally. A numerical model for characterizing and optimizing the electro-optical and display properties of BP LCDs in in-plane switching and fringe field switching cells is developed. The simulated voltage-dependent transmittance curves agree well with the measured results. To lower ...
متن کاملLow voltage blue-phase liquid crystal displays
A protrusion electrode structure is proposed to dramatically lower the operation voltage of the emerging blue-phase liquid crystal displays BP-LCDs . Simulation results indicate that the generated horizontal electric field is not only strong but also penetrates deeply into the bulk LC layer. As a result, a low voltage 10 Vrms and reasonably high transmittance 70% BP-LCD can be achieved. This ap...
متن کاملAfter-effects of TFT-LCD display polarity and display colour on the detection of low-contrast objects.
Participants performed a word-non-word discrimination task within a car control display emulated on a thin film transistor liquid-crystal display (TFT-LCD). The task simulated an information read-out from a TFT-LCD-based instrument panel. Subsequently, participants performed a low-contrast object detection task that simulated the detection of objects during night-time driving. In experiment 1, ...
متن کاملExtended Kerr effect in a polymer-stabilized blue-phase liquid crystal composite
Abstract As the electric field increases, the induced birefringence of a polymer-stabilized blue-phase liquid crystal gradually deviates from the conventional Kerr effect and finally saturates. A new convergence model, named extended Kerr effect, is proposed to explain this saturation phenomenon. This model will give a more accurate account on the electro-optic effect of the emerging bluephase ...
