DRIVING CONTROL DEVICE OF ELECTRO-OPTICAL PANEL, ELECTRO-OPTICAL DEVICE, IMAGING APPARATUS, AND DRIVING CONTROL METHOD OF ELECTRO-OPTICAL PANEL

摘要

A control circuit (600) performs a first process in which it is controlled so that power is supplied to a liquid crystal panel (AA) from a power generation circuit (700), and a second process in which it is controlled so that the liquid crystal panel (AA) is driven based on an internal vertical synchronizing signal (Vs2) of which a frequency is higher than that of an external vertical synchronizing signal (Vs1), and a video center voltage (Dref) is applied to each pixel electrode (6) of the liquid crystal panel (AA), and performs a control so that the liquid crystal panel (AA) is driven based on the external vertical synchronizing signal (Vs1), after repeatedly performing the second process with respect to a plurality of the internal vertical synchronizing signals (Vs2), when a display control signal which instructs displaying of an image on the liquid crystal panel (AA) is supplied.

主权项

1. A driving control device of an electro-optical panel which controls driving of the electro-optical panel based on an external vertical synchronizing signal which is supplied from outside, the device comprising:
a power supply unit which supplies power to the electro-optical panel; an internal vertical synchronizing signal supply unit which generates an internal vertical synchronizing signal of which a frequency is higher than that of the external vertical synchronizing signal, and outputs the signal; and a control unit, wherein, when a display control signal which instructs displaying of an image on the electro-optical panel is supplied, the control unit performs a first process in which it is controlled so that power is supplied to the electro-optical panel from the power supply unit, and a second process in which it is controlled so that the electro-optical panel is driven based on the internal vertical synchronizing signal, and a predetermined voltage is applied to each pixel electrode of the electro-optical panel, and the electro-optical panel is driven based on the external vertical synchronizing signal after repeatedly performing the second process with respect to a plurality of the internal vertical synchronizing signals.
