Abstract: A light collimating system, comprising a transparent substrate, a plurality of conic elements and a screen. Each of the conic elements has a relatively narrow light incident side to which the screen is attached and a relatively wide light emitting side attached to the transparent substrate. Each of the conic elements has several straight or curved segments which are arranged to form a truncated cone with an opening angle that decreases towards the light emitting side. The screen has a plurality of transmission areas covered by the light incident sides of the conic elements. Outside the transmission areas, incoming light is reflected from the screen. Diffuse light entering the conic elements through the transmission areas of the screen is collimated by refraction and total reflection at peripheral surfaces of the conic elements, resulting in a light bundle of narrow angular intensity distribution emanating from the transparent substrate.

Abstract: A process method of using excimer laser for forming micro spherical and non-spherical polymeric structure array includes a photomask which has a selected curved pattern formed thereon. The curved pattern has non-constant widths along a straight line direction. An excimer laser beam source is deployed to project through the photomask on a substrate coated with a polymeric material while the substrate is moving in a direction normal to the straight line direction for the polymeric material to receive laser beam projection with different time period. The polymeric material thus may be etched to different depth to form a three dimensional pattern desired. By projecting and etching the polymeric material two times at different directions or through different photomask patterns, a sphere like or non-sphere like surface of micro array structure may be obtained.

Abstract: A front lighting assembly light guide, comprising a light guide and a plurality of microstructures thereon. The light guide is laid on a front surface of a reflective LCD panel. A light source is placed at one end of the light guide. The plurality of microstructures are placed on a front surface of the light guide, deflecting light from the light source towards the LCD panel, illuminating the LCD panel. The plurality of microstructures are located isolated from each other, allowing to be distributed on the surface of the light guide at a spatial density according to the spatial intensity distribution of light from the light source, the density of microstructures increasing with lower light intensity. Thus uniform illumination of the LCD panel is achieved.

Abstract: A production method of a light guide and a stamper, combining anisotropic etching and isotropic etching. First a plurality of microstructures is formed on a back surface and a front surface of the substrate. By electroforming, rear and front stampers are made from the back and front surfaces of the substrate. Light guides are produced using the rear and front stampers. Anisotropic etching is performed on the front surface of the substrate, forming V-shaped, U-shaped or pyramid like microstructures. Isotropic etching is performed on the back surface of the substrate, forming quadratic, bowl like, oval or semicircular microstructures. If a transparent substrate is used, then after finishing the etching of microstructures, a light source, a reflector, a diffusion sheet and a prism sheet are added, simulating a back light module for performing a test of luminosity, uniformity of light intensity and light emission angle, so that optical properties are known before proceeding with inverse-forming of the stampers.
