  • Publication number: 20060274008
    Abstract: A transflective liquid crystal display having a plurality of pixels, each pixel having a plurality of color sub-pixels, each sub-pixel having a transmission area associated with a first charge storage capacitance and a reflection area associated with a second storage capacitance. In the sub-pixel, a data line, a first gate line, a second gate line and a common line are used to control the operational voltage on the liquid crystal layer associated with the sub-pixel. The first and second gate lines are separately set at a first state and a second state. The ratio of the first charge storage capacitance to the second charge storage capacitance can be controlled according to the states of the gate lines. The second charge storage capacitance is provided by two capacitors connected in parallel through a switching element which can be open or closed according to the states of the gate lines.

  • Publication number: 20060018633
    Abstract: A digital video (DV) storage system comprises an interface module receiving an incoming signal and converting the incoming signal into an incoming bit-stream; a DV demuxer directly connected to the interface module for receiving the incoming bit-stream, wherein the DV demuxer de-multiplexes received blocks in the incoming bit-stream into at least video blocks being in video sections and audio blocks being in audio sections; and memory coupled to the DV demuxer for storing the video blocks and audio blocks. By directly connecting the interface module to the DV demuxer, and by not buffering the incoming bit-stream outside the interface module and the DV demuxer, the memory bandwidth requirement of the memory is greatly reduced, and the interface module and the DV demuxer can be easily implemented together in a single IC.

  • Publication number: 20050264717
    Abstract: A three-dimensional (3D) display system includes a liquid crystal display and a directional backlight module. The backlight module disposed behind the liquid crystal display includes a light-guide plate, a focusing layer, a left backlight source, a right backlight source, and a first V-shaped micro-grooved and a second V-shaped micro-grooved structures of the light-guide plate. The focusing layer is disposed between the light-guide plate and the liquid crystal display. The 3D display method is to instantly switch on and off the left and the right backlight sources to alternately emit the light from the left side and right side of light-guide plate. By means of the first and the second V-shaped micro-grooved structure, the light transmitted from the light-guide plate is focused by the focusing layer within a particular range of angles and passing through the liquid crystal layer for being alternately projected to form a 3D image.
