A transmission device for a photo conductor drum includes a shell, a limiting apparatus mounted in the shell and having a through hole, and a transmission shaft which is coaxial with the through hole at a beginning position. When the transmission shaft is moved axially by an external force to a pressed position, the transmission shaft is inclinable relative to the through hole, and when the external force is released, an elastic member will force the transmission shaft to move back to the beginning position. As a result, while the photo conductor drum is put into a housing of a printer, the transmission shaft can connect a driving shaft without a help of a guider for enabling the photo conductor drum to rotate steady and smoothly.

An autostereoscopic display device having touch sensing mechanism includes a display panel for illustrating images, a touch sensing panel for detecting touch events, a 2D/3D switching panel disposed between the display panel and the touch sensing panel, and a control unit. The 2D/3D switching panel has a substrate, a first electrode disposed on the substrate, a counter substrate, and a second electrode disposed on the counter substrate. The control unit is employed to provide a first control signal and a second control signal furnished to the first electrode and the second electrode respectively. The first control signal is switched between a first high voltage and a first low voltage in a gradual-shift manner. The second control signal is switched between a second high voltage and a second low voltage in a gradual-shift or rapid-shift manner.

A driving unit for a photo conductor drum cartridge is assembled with a shaft of the photo conductor drum cartridge, including a gear and a conducting plate mounted on the gear. The conducting plate is provided with an elastic arm and defines an imaginary axis parallel to the shaft. When the elastic arm of the conducting plate is perpendicular to the imaginary axis, a distance L is defined between a distal end of the elastic arm and the imaginary axis. The distance L is longer than or equal to a radius d of an annular groove portion of the shaft and shorter than a radius D of the shaft. By means of this design, the driving unit can be reusable and provide a convenient detachment of a photo conductor drum.

A noise suppressing method for switching on/off a flat panel display. A signal detect circuit and a video signal processor are embedded in a time controller IC. At the switch-on transient, the signal detect circuit functions to detect whether the signal is stable. When an unstable signal is detected, the video signal processor controls the driver IC to output a black burst signal. At the switch-off transient, the signal detect circuit is used to detect the switch-off signal. When the switch-off signal is detected, the video signal processor controls the driver IC to output a charge reset signal. The flat panel display is switched off after the charge reset operation is performed for all the pixels.

A liquid crystal display. The liquid crystal display having a power device, a display unit array, a scan driver, a selection device, and a current limiting device. In normal operation of the liquid crystal display, according to the operation of the selection device, a voltage signal applied from the power device is directly applied to the scan driver according to the selection device, and the scan driver sequentially outputs scan signals to scan electrodes. During shutdown and power on processes of the liquid crystal display, according to the operation of the selection device, the voltage signal applied from the power device is applied to the scan driver through the current limiting device, limiting the instantaneous current from the power device. Moreover, the scan driver simultaneously outputs all the scan signals to erase charges within all the display units.

A structure capable of reducing the amount of transferred digital image data of a digital display has a digital image and timing control unit for controlling the receiving and transfer of image data and providing timing control. The digital image and timing control unit includes at least one first and second registers, a data address flag unit, and a control logic. The first and second registers serves to buffer the image data of the n-th image data line and (n+1)-th image data line. The control logic compares the image data and enables the flags in the data address flag unit corresponding to the image position to be updated, so as to determine the image data to be transferred.
