Title:
【発明の名称】フラットパネル液晶表示バックライト装置のプリズム屈折光学アレイ
Document Type and Number:
Japanese Patent JPH10510929
Kind Code:
A
Abstract:
A prismatic refracting array for a flat panel liquid crystal display (LCD) backlighting device matches a prismatic angle with the critical angle of the exit window and surrounding material, e.g., glass and air. By selecting the prism angle of the refracting array with reference to the critical angle of the exit window and surrounding air, light lost to total internal reflectance within the exit window is substantially eliminated while directing all light output within selected view angles. By better utilizing the available light output from the flat panel backlight device, overall efficiency of the LCD device is improved.
