Abstract
There are provided an apparatus for supplying gate driving voltages, a method for supplying gate driving voltages and a display apparatus to which the apparatus for supplying gate driving voltages is applied to. In the apparatus for supplying gate driving voltages, there is disposed a starting voltage boost module connected with a starting voltage output module. The starting voltage boost module is configured to boost a second preset voltage to a third preset voltage higher than a first preset voltage in advance within a predetermined period of time when the second preset voltage is restored to the first preset voltage. By means of the third preset voltage with a higher voltage, the time taken by a gate ON voltage to be restored to the first preset voltage from the second preset voltage is shortened, a response speed is quicken and a problem of too slow restoration due to a large load is settled, so that a charging time of a liquid crystal display panel is increased and the display quality of the picture is enhanced.
