Abstract:
An oscillator circuit wherein the impedance at the output terminal can be selectively decreased for a short period of time to thereby increase the closed loop gain is provided. The oscillator circuit includes a quartz crystal vibrator and a C-MOS inverter having a drain output terminal for producing a high frequency signal thereat, the gate output terminal being fed back through the quartz crystal vibrator to a gate input terminal to define a predetermined closed loop gain. The invention is particularly characterized by a control circuit external to the oscillator circuit that is adapted to produce a control signal for a predetermined period of time. A secondary inverter is provided and is adapted to be selectively coupled, in parallel, with the C-MOS inverter during the period of time that the control signal is applied thereto, to thereby reduce the impedance at the output terminal of the C-MOS inverter and increase the closed loop gain during the predetermined period of time that the control signal is applied thereto.

The invention provides an electro-optical device that stabilizes display quality by performing correction processing corresponding to a plurality of disturbance factors. Specifically, a grayscale characteristic generating unit can generate conversion data having grayscale characteristics obtained by changing the grayscale characteristics of display data that defines the grayscales of pixels with reference to a conversion table whose description contents include correction factors. A data line driving circuit can drive the pixels after correcting the grayscale characteristics of the conversion data by the correction factors using other processing different from the that performed by the grayscale characteristic generating unit.
