SCANNING SIGNAL LINE DRIVE CIRCUIT AND DISPLAY DEVICE EQUIPPED WITH SAID CIRCUIT Russian patent published in 2014 - IPC G09G3/36 G02F1/133 

FIELD: physics, computer engineering.

SUBSTANCE: group of inventions relates to computer engineering and can be used in display devices. The scanning signal line drive circuit of a display device comprises a plurality of shift registers, each including a plurality of circuits with two stable states, wherein a clock signal provided in each shift register as a clock signal for driving the scanning signal line varies between a first level and a second level at specific clocking, which differs from one shift register to the other, each circuit with two stable states having an output unit, a switching element for controlling the output, a unit for turning on the first unit and a unit for turning off the first unit.

EFFECT: preventing inaccurate display owing to fast lowering of the scanning signal level once the charge period in each line ends.
