Electro-optical device, its driving circuit, driving method and electronic apparatus

Abstract

To improve the display quality of a moving picture by performing a hold-type display of a liquid crystal, etc. using an impulse-type response. A selection voltage is applied to a selected scanning line during an effective horizontal scan period, and a voltage corresponding to the brightness of a pixel corresponding to an intersection with the selected scanning line is applied to one data line. During a horizontal flyback period when another scanning line is selected, a selection voltage is applied to the selected scanning line and a voltage allowing the pixel to display black as the least brightness is applied to the data line. As a result, the display of the pixel is erased and the data lines are precharged with the voltage erasing the display, for preparation of the subsequent writing operation.

Description

technical field [0001] The present invention relates to an electro-optic device suitable, for example, for the display of images with motion. A driving circuit for an electro-optical device, a driving method for an electro-optical device, and an electronic device. Background technique [0002] In recent years, electro-optic devices such as liquid crystals that display by electro-optic changes have been widely used in various electronic equipment or televisions as display devices that replace cathode ray tubes (CRTs) due to their advantages such as thinness, small size, and low power consumption. Apply it. [0003] Although this electro-optic device can be roughly classified into an active matrix type in which pixels are driven by switches and a cell-source matrix type in which pixels are driven without switching elements, if the electro-optic device is classified according to the driving method, etc., among them, the active matrix type based on the former In the type, sinc...

Problems solved by technology

[0007] However, in the above-mentioned technologies, although the display quality of moving images is improved by impulsive display, there is a disadvantage that high-speed writing is required.

The reason is that in the technology of setting a non-display field between a certain frame and the next frame, the period for scanning is shortened due to the period of the non-display field, and the black is written in the same period after the signal for display is written. In the level signal technology, since it is necessary to select the scanning line twice, the period for writing the display signal is halved.
