Due to lights with different wavelengths having different indexes of refraction in a liquid crystal, a retardation between lights with different wavelengths occurs and causes the problem of viewing angle of the liquid crystal display. The present invention provides a manufacturing method of light-guiding apparatus of a liquid crystal display to form light-guiding pillars having a characteristic of total reflection as a fiber. The light from back light module through the light-guiding pillars enters the liquid crystal at an incident angle smaller than 150 for reducing the retardation between lights with different wavelengths.
A method for manufacturing a diffuser for a backlight module is disclosed. The method includes providing a transparent substrate; forming a first transparent photoresist layer on the transparent substrate; spreading a plurality of masking particles on the first transparent photoresist layer; exposing and developing the first transparent photoresist layer; removing the masking particles; etching the exposed region of the first transparent photoresist layer to form a first scattering array; and optionally forming a passivation layer on the first transparent photoresist layer.
An image matching apparatus includes a numerical analyzing unit that solves an equation of motion numerically. The equation of motion is formulated as an image matching state transition model representing a mapping relation between a source image and a destination image. The equation of motion represents a force applied on each lattice point of the destination image including potential energy force. The numerical analyzing unit calculates the potential energy force, and sets a convergence value of a solution of the equation of motion as a mapping relation between the lattice point of the source image and the lattice point of the destination image based on the numerical analysis.
