  • Patent number: 7414824
    Abstract: A storage capacitor having a scattering effect is positioned in a substrate for use in a thin film transistor array loop. The storage capacitor is characterized by having a rough layer overlapped by a medium layer and a passivation layer. The storage capacitor further has a reflective layer with high reflectivity so as to provide the storage capacitor with the scattering effect toward an external light source. A method of manufacturing the storage capacitor by two photolithography processes is also shown.

  • Patent number: 7077557
    Abstract: A surface light source device. A light guide plate has an incident end face, an emitting face, at least one full-reflective face, and a plurality of light adjusters. The full-reflective face reflects light onto the incident end face for direction to the emitting face for transmission. The light adjusters are disposed in the light guide plate with a density discontinuously varied in at least one area of the light guide plate to adjust light collection for emission from the different areas of the emitting face, hereby providing discontinuous light intensity. The light source is disposed in the vicinity of the incident end face.

  • Patent number: 7038749
    Abstract: 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.

  • Patent number: 7033058
    Abstract: 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.
