A driving system and a method for a dot-matrix light-emitting diode display device. The driving system comprises a controller, a scan line driver, and a signal line driver. The controller provides a scan line control signal and a signal line control signal. The scan line driver generates a scan line driving signal in response to the scan line control signal. The scan line driving signal is divided into an ON period and a OFF period. The signal line driver generates a signal line driving signal in response to the signal line control signal. The signal line driver generates a discharging control signal or a charging control signal during the OFF period so that the signal line driver and the plurality of signal lines form the discharging or charging paths. Therefore, the parasitic capacitors on the scan lines are discharged or the parasitic capacitors on the signal lines are charged.

A method for manufacturing a thin film solar cell involves applying an inductively-coupled-plasma during the deposition of selenium. A precursor thin film is formed. The precursor thin film can include copper, indium, and gallium. The inductively-coupled-plasma is applied to the selenium as the selenium is deposited into the precursor thin film to produce the thin film. The selenium is deposited into precursor thin film by evaporation, sputtering, or using a reactive gas. An inert gas is used as a carry and discharge gas. The precursor thin film and the selenium are deposited using a deposition system. The deposition system includes an inductively-coupled-plasma device. The inductively-coupled-plasma device includes a quartz plate, a plasma discharge coil, and an inlet system. The deposition can be an in-line system, a roll-to-roll system, or a hybrid system.

A scan-type display device control circuit is suitable for receiving successive frame data and driving a light-emitting diode (LED) display device accordingly. The scan-type display device control circuit includes a ping-pong buffer, a data storage controller, a line scan controller, a display buffer, and a scrambled pulse width modulation (PMW) signal generating device. The scan-type display device control circuit can utilize frame data circularly and repeatedly, so as to prevent a great mass of data from being transmitted repeatedly. Therefore, a band width for inputting data can be reduced significantly. Furthermore, the scrambled PMW signal generating device can scramble a PMW signal with a long period into a plurality of scrambled PMW signals with a short period. Therefore, the refresh rate can be efficiently enhanced without changing the band width for inputting data.

A serial controller is adapted to receive an external clock and an input data, and output an inverted clock and an output data. The serial controller includes an inverter, a serial position detector, a synchronous clock generator, a serial register, and a half-cycle delay unit. Thereby, through the serial controller, the problem that the data signal and the driving clock are not synchronous when the clock series are inverted is avoided. Besides, a bi-directional serial controller further includes an identification unit and a data directing unit, and the serial controller is enabled to return the current status to a central control unit to serve as the reference for error detection.

A system and method for network simulation and enhancement includes an experiment configuration engine that provides various proposed traffic and/or network models, and a simulator responsive to the proposed traffic and/or network models to execute a plurality of simulations for the network using parallel discrete event simulation, to determine an optimal network configuration based upon an objective function for enhancing an aspect of network performance. The traffic and/or network models may be based on monitored data from the network indicating a current network state and current network traffic. Reconfiguration instructions for the new network configuration may be conveyed from the simulator to the network, so as to effectuate ongoing, real-time enhancement of the network. The network model(s) may cover internal operational details of individual network devices (e.g., routers and/or switches) as well as operation of the network as a whole.
