Abstract

Настоящее изобретение предоставляет схему драйвера затвора и способ управления. Схема содержит многокаскадные схемы GOA, схема GOA N-ого каскада которых содержит блок зарядки, электрически подсоединенный между (N-1)-ой затворной шиной и блоком накопления энергии и использующийся для предварительной зарядки блока накопления энергии в соответствии с сигналом (N-1)-ой затворной шины для получения напряжения; управляющий блок для повышения сигнала N-ой затворной шины до повышенного напряжения в соответствии с напряжением и тактовым импульсным сигналом; первый блок сброса, использующийся для сброса сигнала N-ой затворной шины до первого напряжения сброса или третьего напряжения сброса в соответствии с сигналом затворной шины (N+1) и первым напряжением сброса или третьим напряжением сброса; и второй блок сброса, использующийся для сброса сигнала N-ой затворной шины до второго напряжения сброса в соответствии с сигналом затворной шины (N+3) и вторым напряжением сброса. В схеме настоящего изобретения два блока сброса используются для достижения управления четвертого порядка для блоков пикселей, таким образом, эффективно решая проблему влияния проходного напряжения на электрод пикселя и улучшая эффект качества изображений.
