Abstract: Optical compensation films based on polymer blends formed from particular compositions of a styrenic fluoropolymer and acrylic copolymers are provided. The optical compensation films have desirable mechanical and optical properties such as haze, elongation at break, Young's modulus, in-plane retardation, and out-of-plane retardation. The optical compensation films are suitable for use in display devices such as those in televisions, computers, automobiles, and mobile phones.

Abstract: A multi-region imaging device (1000?, 2000) and method (9000?). The multi-region imaging device (1000?, 2000) comprises: a picture light projection plate (1100?, 2100?), wherein the picture light projection plate (1100?, 2100?) comprises a first region (1110?, 2110?) and a second region (1120?, 2120?) that do not overlap each other, the first region (1110?, 2110?) and the second region (1120?, 2120?) emit picture light for imaging; and an optical path compensation section (1200?, 2200?), wherein the optical path compensation section (1200?, 2200?) is arranged on a propagation path of the picture light emitted by the second region (1120?, 2120?), and the picture light emitted by the second region (1120?, 2120?) is transmitted by the optical path compensation section (1200?, 2200?) and optical path compensation is carried out thereon.

Abstract: Disclosed is a process for making nitrated styrenic fluoropolymers having various degrees of substitution. The nitrated styrenic fluoropolymer is capable of providing an exceptionally high birefringence ranging from 0.02 to 0.036. Further, the birefringence can be tuned by varying the degree of substitution (DS) of the nitro group on the styrenic ring to meet the need for optical compensation film applications. More particularly, the optical compensation films of the present invention are for use in an in-plane switching LCD (IPS-LCD) and OLED display.

Abstract: Disclosed is an optical compensation film made of a solution cast of a polymer blend comprising a nitrated styrenic fluoropolymer and a polyimide. The compensation film is a positive-C plate having reversed wavelength dispersion that is capable of providing an achromatic (or broadband) retardation compensation. The optical film of the invention can be used in an optical device such as liquid crystal display (LCD) or organic light emitting diode (OLED) display.

Abstract: Disclosed is a multilayer optical compensation film comprising a first layer comprising a positive C-plate material and a second layer comprising a polyimide, as well as polymer compositions and resins and solutions containing said polymer compositions. The optical compensation film has a reversed wavelength dispersion that is capable of providing an achromatic (or broadband) retardation compensation. The optical film can be used in optical devices such as liquid crystal displays (LCD) or organic light emitting diode (OLED) displays.

Abstract: A polymer blend includes a combination of an acrylic polymer and a styrenic fluoropolymer. The polymer blend may be used to make polymer films having a single glass transition temperature, a polarizing plate, or a display device with enhanced optical properties.

Abstract: Disclosed are optical compensation films with exceptionally high positive out-of-plane birefringence. The optical compensation films are based on substituted styrenic fluoropolymers and have positive out-of-plane bireftingence greater than 0.02 throughout the wavelength range of 400 nm<?<800 nm. The optical compensation films of the invention are suitable for use in optical devices such as liquid crystal display (LCD) devices and organic light emitting diode (OLED) display devices.
