For itb, design multi-directional non-alignment: micro lens The array light control film can receive ambient light from multiple directions, so the moon dagger greatly improves the brightness and quality of the display. "" Province-known light control film (LCF) such as the Republic of China Patent No. 5; [2 2 50's light distribution control element applied to reflective liquid crystal displays and the use of the two elements of said liquid crystal display display device ", is a kind of The light control element is a light control sheet, a light control film, or a surface change having such a light control function, which can change the light distribution of the image of the reverse LCD display. As in the conventional manufacturing method, the structure must be built on a light-transmitting plastic sheet or plastic knee film, and if the effect of the light control film (LCF) is obvious, the light film (LCF) must be attached to the upper polarizer. Below, at this time, in order to avoid the birefringence effect of the plastic sheet or plastic film from shifting the display color, it is necessary to use expensive low birefringence materials. The original design of the current light control film (LCF) was' the microlens array ( micr〇iens array) is based on a thin birefringence film such as a cycloolefin smoke copolymer (C yc 1 0 0 1 ef 丨 nc ο ρ ο 1 ymer; C〇C) film, but it has a low birefringence The rate of the film is expensive, and furthermore, due to the light transmission of the film and the reflection of the interface of the bonding surface, the intensity of the light will be attenuated after passing through the film.
