  • Patent number: 7075505
    Abstract: It is one object of the present invention to reduce the number of inputs to an LCD driver and to reduce manufacturing costs by employing the COG&WOA technique. For a liquid crystal display device, source driver ICs 20, among which video signals are transmitted and distributed via a video I/F 3, are cascade-connected, and the connection lines to the source driver ICs 20 are reduced as much as possible to employ the COG&WOA technique. That is, a liquid crystal display device comprises: a liquid crystal cell 2, which forms an image display area on a substrate, and a source driver 7, which applies a voltage to the liquid crystal cell 2 based on a video signal input via a video I/F 3. The source driver 7 includes a plurality of source driver ICs 20 that are mounted on the same substrate as the liquid crystal cell 2 and that are cascade-connected by signal lines.

  • Patent number: 6753704
    Abstract: The invention proposes a sampling phase detector in which a first sampling transistor with a very high sensitivity determines the phase of a signal to be sampled. A signal representative of the phase is supplied to a second sampling stage. The second sampling stage retains the phase value determined in this way. The invention provides a phase signal that is more stable and more sensitive. The invention also provides a method and an oscillator employing the method.
