摘要： A reflector structure in a liquid crystal display having light condensing effect comprises mainly an active device substrate, a condenser having diffraction or refraction effect being formed above the substrate, a spacing layer being formed above and covering the condenser, and a reflective unit being formed above the spacing layer. The condenser can be a holographic diffraction unit, micro prisms or micro lens unit. It can be on a TFT substrate or a color filter. The color filter can be located at the same or opposite side with the TFT substrate. The spacing layer may be an over coat layer, a color filter, a color filter and an over coat layer on the color filter, or a substrate. The reflective unit also has various structures, reflective angles, and reflective effects. The invention utilizes the condenser to collect light. 60% to 95% of unused backlight is collected. The backlight gain is over 120% to 400%, thereby greatly saving the power consumption for the backlight source.

摘要： A flat display displays images on both sides is disclosed. The flat display includes a liquid crystal molecule layer disposed between two substrates, and a driving array having a plurality of switch devices disposed on one of the substrates. Images are asynchronously displayed on both sides of the flat display by controlling a rotation state of the liquid crystal molecule layer by the driving array in cooperation with a light source provided by a light source module. The light source module includes two light-guiding plates. One of the light-guiding plates is disposed on the substrate having the driving array, and the other light-guiding plate is disposed on the other substrate having a color filter.

摘要： A liquid crystal display has at least one concave structure formed on one of pixel and electrode layers in each pixel area. Between the electrode layer having concave structures and a substrate is a passivation layer that is dented by the concave structures. The concave structures form multiple domains for each pixel. One of the electrode layers may be formed with bump structures or openings combining with fringe field effect to provide pre-tilting of liquid crystals to enhance the effect of multiple domains. Each concave structure in a pixel area can have a different top view, cross-sectional view or three-dimensional structure. The concave structure can be formed by existing manufacturing process. One mask rubbing process or photo-aligned method may be used to align liquid crystals for the display in cooperation with the concave structures.

摘要： A multi-domain liquid crystal display (LCD) has a plurality of wall-bump structures formed on a common electrode layer on a substrate. Each wall-bump structure consists of at least one wall-bump disposed in a pixel area. Wall-bumps of many different shapes can be used in the wall-bump structure. The wall-bump structure is manufactured by a standard photo-lithographic process. It provides pre-tilted angles for liquid crystal molecules and results in orderly alignment of liquid crystal molecules when an external voltage is applied. By means of the fringe field effect to tilt liquid crystal molecules, a multi-domain LCD cell can be established after a voltage is applied. The multi-domain LCD provides fast response speed for its application and higher transmittance than a conventional vertically aligned wide-viewing angle LCD.
