发明名称 Select line driver for a display matrix with toggling backplane
摘要 When a given row in an array of a liquid crystal display having a toggling backplane voltage is de-selected, the row select line voltage also toggles to prevent capacitive current in the pixel capacitance. The row select line driver includes a pair of transistors coupled in a push-pull configuration. The pair of transistors are responsive to a control signal that is produced in a corresponding stage of cascaded stages of a shift register. The pair of transistors form a buffer stage that prevents the toggling voltage developed in the row select line when the row is de-selected from affecting the operation of the shift register.
