Abstract
A maintenance circuit for a display panel, the display panel being divided by a plurality of source driver integrated circuits into a plurality of partitions(X-X) corresponding thereto, wherein each of source driver integrated circuits controls one partition, each four of adjacent partitions form a group of partitions, each of the maintenance circuit units comprises: a first maintenance line(RP, RP) and a second maintenance line(RP, RP) each provided with a half-turn shape surrounding around a group of partitions corresponding thereto; a first operational amplifier(OP, OP) and a second operational amplifier(OP, OP), the inverting input terminal of each of which is connected to an output terminal thereof and is connected to a corresponding maintenance line; and a plurality of resistors(R-R, L-L) selectively connected in accordance with two partitions of the group of the partitions to be maintained, so as to respectively import the two partitions to non-inverting input terminals of the two operational amplifiers via signals outputted from a corresponding source driver integrated circuits, and to feed the signals outputted from the two operational amplifiers back to the corresponding partitions.
