Abstract

The present invention is directed to a liquid crystal display apparatus including: a timing circuit for operating a shift register within a timing circuit during a vertical blanking period such that a common signal that has been alternated at a cycle of a Single Horizontal period is applied on counter electrodes during the vertical blanking period and such that a storage electrode signal is applied on storage electrodes having a frequency, phase and amplitude identical to those of the common signal.

Claims (4)

1. A liquid crystal display apparatus comprising:

a timing circuit in which a DC level of a variable source signal is set to a Gray level for a line following a last line, the Gray level having an amplitude smaller than that of a black level, and wherein the Gray level variable source signal is applied on source lines during the vertical blanking period.

2. A method for driving a liquid crystal display apparatus comprising:

applying a variable source signal having a DC level set at a Gray level electric potential on source lines during a vertical blanking period for decreasing effective voltage differences between odd-numbered lines and even-numbered lines and for decreasing luminance differences per gate line, the Gray level having an amplitude smaller than that of a black level.
