DISPLAY HAVING LIGHT SCATTERING ELECTRO-OPTICAL ELEMENT |
摘要 |
A display having a first electrode means; a second electrode means; and a display medium positioned between the first and second electrode means, which display medium contains a pleochroic dye, is switchable between a first state in which incident light is substantially absorbed by the pleochroic dye and a second state in which the amount of such absorption is substantially reduced, and is capable of scattering incident light with a scattering half angle between about 5 and about 40 degrees when the display medium is in its second state, while permitting at least 10% of the incident light to be transmitted. The absolute difference between the ordinary index of refraction of the liquid crystal and the refractive index of the containment medium is 0.10 to 0.20.
