    摘要: A cam gear is provided with a camming groove including an inside camming face and an outside camming face. The inside camming face is divided into a stop mode inner-section of a first constant radius, a play mode inner-section of a second constant radius, the second constant radius being larger than the first radius, and a first transition section formed in a manner that an end of the stop mode inner-section is smoothly joined to a beginning of the play mode inner-section. The outside camming face is divided into a stop mode outer-section of a third constant radius, the third constant radius being larger than the first constant radius by a predetermined camming groove width, a play mode outer-section of a fourth constant radius, the fourth constant radius being larger than the second radius by the camming groove width, an intermediate mode outer-section of a fifth constant radius, the fifth constant radius being larger than the third constant radius and being smaller than the fourth constant radius, a second transition section formed in a manner that an end of the stop mode outer-section is smoothly joined to a beginning of the intermediate mode outer-section, and a third transition section formed in a manner that an end of the intermediate mode outer-section is smoothly joined to a beginning of the play mode outer-section.

    摘要: A method of driving a display panel includes applying a common voltage to the display panel, sensing a frequency of the display panel to generate a frequency signal, adjusting a gain of an operational amplifier based on the frequency signal, receiving a feedback common voltage from the display panel, and compensating the common voltage using an input resistor, the operational amplifier and a feedback resistor based on the feedback common voltage to apply the compensated common voltage to the display panel. The operational amplifier includes an inverting input terminal connected to the input resistor, a non-inverting input terminal to which a reference common voltage is applied and an output terminal. The feedback resistor is between the inverting input terminal and the output terminal.
