摘要： The present invention relates to a driving circuit for a display panel, and comprises a switching module, a buffer circuit, and a plurality of resistive devices. The switching module is coupled to a first power supply and a second power supply. The voltage of the first power supply is smaller than that of the second power supply. The buffer circuit is coupled to the switching module, and is used for buffering a data signal and producing a buffer signal. The plurality of resistive devices is connected in series and coupled to the buffer circuit, and produces a plurality of driving signals between the plurality of resistive devices according to the buffer signal. The driving circuit switches between the first power supply and second power supply sequentially to supply power to the buffer circuit. Thereby, one of the plurality of driving signals charges a capacitor of the display panel for saving power of the driving circuit. Accordingly, the power of the display can be saved.

摘要： The present invention relates to a driving circuit for a display panel, which comprises a pre-charge power supply, a pre-charge switch, a buffer circuit, and a plurality of resistive devices. The pre-charge switch is coupled between the pre-charge power supply and a capacitor of the display panel. The buffer circuit is used for buffering a data signal and producing a buffer signal. The plurality of resistive devices is connected in series and coupled to the buffer circuit, and produces a plurality of driving signals therebetween according to the buffer signal. The driving circuit first closes the pre-charge switch to make the pre-charge power supply charge the capacitor. Then, one of the plurality of driving signals charges the capacitor. Thereby, the driving time can be shortened, and power of the display can be saved by avoiding power consumption on resistors.

摘要： In a closed-loop monitoring system, a host device is operable to output encoded signals at a coupling side to a single transmission line. Each of monitoring devices includes: a current inducting generating unit generating induced encoded signals when the encoded signals pass through a signal current generating element coupled across an input side coupled to the transmission line; a control unit identifying a monitoring signal from the induced encoded signals generated by the current inducting generating unit; and a detecting unit detecting, in response to the monitoring signal, whether each of electronic devices coupled thereto is activated ox deactivated and transmitting a reply signal associated with states of the electronic devices to the transmission line based on a detection result made thereby. The host device receives the reply signal from each monitoring device through the transmission line and the coupling side to obtain state information associated with the electronic devices.

摘要： A low power source driving device adopted for use on liquid crystal drivers includes a time series controlled digital circuit to generate different digital signal combinations and a dynamically regulated source driver bias circuit to regulate by stages bias currents of source drivers according to the digital signal combinations so that output can reach a Gamma potential while power consumption is reduced at the same time. Increasing the stage number of the bias currents can further reduce power consumption.
