1. A display device, comprising a display panel and a source driver connected to the display panel, wherein the display panel comprises a plurality of horizontal display areas from being close to the source driver to far away from the source driver;
wherein the source driver is configured to respectively output different driving current intervals through a plurality of input channels to correspondingly drive the plurality of horizontal display areas from being close to the source driver to far away from the source driver,
wherein the driving current intervals corresponding to the plurality of horizontal display areas from being close to the source driver to far away from the source driver gradually increase,
wherein the source driver comprises at least one multi-output adjustable current source, the plurality of input channels are respectively connected with the multi-output adjustable current source, and the multi-output adjustable current source is configured to output a corresponding driving current interval to drive one of the plurality of horizontal display areas, and
each of the plurality of horizontal display areas is divided into a left sub-area, a middle sub-area, and a right sub-area, and the adjustable current source is further configured to output currents that increase in magnitude bidirectionally starting from the middle sub-area and expanding out to both the left sub-area and the right sub-area and are from respective driving current interval corresponding to the each horizontal display area.
