摘要： This invention describes methods and circuits for the segment driver circuit in a LCD driver system as well as application specific SEG decoder. The methods include the following steps: the array signal undergoes an inversion process (from 1 to 0, or from 0 to 1); the data and the array signal that has been processed through the inversion process then undergo a matrix operation; the signal that has gone through the matrix operation is then sent to a BBM (break before make) circuit. The signal processor of the application specific SEG decoder performs the inverse operation (from 1 to 0, or from 0 to 1) on the array signal; the decoding circuit performs the matrix operation on the signal that has been inversed (from 1 to 0, or from 0 to 1) before sending it to the BBM circuit. The methods described in this invention first process the array signal through field processing and inverse processing (from 1 to 0, or from 0 to 1) before undergoing the matrix operation, rather than first performing the matrix operation and then selecting an output based on the field signal. Therefore, this invention enhances the SEG decoder by simplifying the circuitry, reducing energy consumption, lowering cost, and making it easier to realize.

Said power source circuit includes: a charge pump circuit used to operate the charge pump to produce driving voltages; a first control circuit, used in the closed-loop control of said charge pump circuit to produce a positive high voltage; a bias-ratio circuit, used with the positive high voltage and the zero-potential voltage produced by the first control circuit to produce a positive sub-high voltage and a lowest positive high voltage; and a second control circuit, used in accordance with the positive sub-high voltage and the lowest positive high voltage produced by said bias-ratio circuit in the closed-loop control of said charge pump circuit to produce a negative high voltage. Using this invention, the system contains no voltage higher than the liquid crystal's driving voltages, and also does not contain any lower negative voltage than the liquid crystal's highest negative driving voltage, thereby reducing the circuit's electrical consumption.
