Abstract:
The present invention provides a compound capable of forming an irregular wrinkled structure, a composition containing the compound, a film having the irregular wrinkled structure, a method of forming the film, and an organic light emitting diode comprising the film. The film can be formed with the irregular wrinkled structure by simply coating the compound of the present invention, and curing using UV rays or heat. By applying the formed film to the organic light emitting diode, light emitted from the organic light emitting diode is scattered on the surface of irregular wrinkles and is extracted to the outside after controlling the optical wave or total reflection. A random structure located on the outside of the diode functions as a light extraction unit for improving the light efficiency of the organic light emitting diode.

PURPOSE: A display device is provided to be installed in a wall or column of a curved surface as being able to be kept or displayed in a roll type. CONSTITUTION: A display device comprises a plurality of channels to form a specific pattern. Each channel includes a light source module, a driver module, an optical waveguide and a scattering pattern. The light source module includes a light source generating an optical signal with different wavelengths. The driver module adjusts on/off or intensity of the optical signal generated in the light source module. The optical waveguide delivers the optical signal generated in the light source module without external loss. The scattering pattern scatters the optical signal delivered through the optical waveguide to display externally.

PURPOSE: An optical film produced from a polymer substance is provided to minimize trapped mode light by containing high refractive material with a refractive index same as an organic light emitting layer. CONSTITUTION: A polymer substance contains a polymer matrix (110); a high refractive material which is chemically combined to the polymer matrix; and a low refractive material with lower refractive index than that of the high refractive material being chemically combined to the high refractive material. The high refractive material and the low refractive material are chemically combined together in the polymer matrix. The low refractive material leaves from the polymer matrix at lower temperature than that of the high refractive material. The organic light emitting diode contains a light emitting layer; and a film layer which increases light extracting efficiency of light irradiated from the organic light emitting layer.

PURPOSE: An optical touch screen panel is provided to sense a touch location by using an optical detection array and a beam deflector. CONSTITUTION: An optical source unit(203,204) generates a parallel ray which is parallel to a horizontal axis or a vertical axis of a touch screen. A first beam deflection unit increases width of the horizontal axis according to the width of a horizontal-axis touch screen. A second beam deflection unit reduces the width of the parallel ray. An optical detection unit detects a touch location of an object about touch screen.

Abstract:
An apparatus for controlling dispersion of optical signals is provided to variably control or correct color dispersion and polarizing mode dispersion generated in an optical fiber transmission path of a high speed optical transmission system. An apparatus for controlling dispersion of optical signals includes a color dispersion control part(200) and a polarizing conversion part(100). The color dispersion control part indicates different color dispersion control properties about optical signals of two polarizing modes. The polarizing conversion part receives the optical signals inputted from outside, and transmits the optical signals to the color dispersion control part after converting a polarizing state of the optical signals into a polarizing state corresponding to one of the polarizing modes.
