Abstract
Abstract In a liquid crystal display apparatus in which a selection signal is simultaneously applied to two scanning signal lines, the application of the selection signal to one of the two scanning signal lines is terminated earlier than that of the selection signal to the other one of the two scanning signal lines. Alternatively, the level of the selection signal to one of the two scanning signal lines is made higher than that of the selection signal to the other one of the two scanning signal lines.

Claim 2
Dependent Claim
104 words
A display apparatus comprising: a display panel having scanning signal lines arranged in parallel, data signal lines, switching elements which are controlled by a signal supplied through said scanning signal lines, pixel electrodes connected to said data signal lines through said switching elements; and drive means for simultaneously applying said signal to at least two succeeding ones of said scanning signal lines, said drive means comprising timing control means for terminating the application of said signal to one of said at least two scanning signal lines earlier than the application of said signal to another one of said at least two scanning signal lines.
Claim 3
Dependent Claim
42 words
A display apparatus according to claim 1, wherein said one scanning signal line is disposed between a pixel electrode to which said one scanning signal line is connected and another pixel electrode to which said other one scanning signal line is connected.
Claim 4
Dependent Claim
28 words
A display apparatus according to claim 1, wherein said drive means comprises clock signal means for supplying at least two clock signals which are phase-shifted from each other.
Claim 5
Dependent Claim
105 words
A display apparatus comprising: a display panel having scanning signal lines arranged in parallel, data signal lines, switching elements which are controlled by a signal supplied through said scanning signal lines, pixel electrodes connected to said data signal lines through said switching elements; and drive means for simultaneously applying said signal to at least two succeeding ones of said scanning signal lines, said drive means comprising voltage means for making the level of said signal applied to one of said at least two scanning signal lines higher than the level of said signal applied to another one of said at least two scanning signal lines.
Claim 6
Dependent Claim
105 words
A display apparatus comprising: a display panel having scanning signal lines arranged in parallel, data signal lines, switching elements which are controlled by a signal supplied through said scanning signal lines, pixel electrodes connected to said data signal lines through said switching elements; and drive means for simultaneously applying said signal to at least two succeeding ones of said scanning signal lines, said drive means comprising voltage means for making the level of said signal applied to one of said at least two scanning signal lines higher than the level of said signal applied to another one of said at least two scanning signal lines.
Claim 7
Dependent Claim
42 words
A display apparatus according to claim 4, wherein said one scanning signal line is disposed between a pixel electrode to which said one scanning signal line is connected and another pixel electrode to which said other one scanning signal line is connected.
Claim 8
Dependent Claim
64 words
Active matrix display apparatus with scanning lines, data lines and pixel electrodes to be activated by data signals on the data lines through switch elements controlled by scanning signals on the scanning lines, wherein the scanning lines are driven at least two adjacent ones at a time but with signals having different signal parameters to provide the same display characteristics on simultaneously driven pixels.
Claim 9
Dependent Claim
