Abstract

The invention relates to the field of display panel manufacturing and provides a display panel power supply device, a manufacturing method, a power supply method and a display device. The display panel power supply device comprises a first line, a first power terminal and a second power terminal. The first line surrounds the display panel and is electrically connected with subpixels of the displaypanel. The first power terminal is arranged at the first end of the display panel and is connected with a first wiring section, located at the first end of the display panel, in the first line. The second power terminal is connected with a second wiring section, located at the second end of the display panel, in the first line to compensate pressure drop of the first power terminal on the first line, and the first end and the second end of the display panel are two opposite ends of the display panel. The brightness attenuation of the display panel from the first end to the second end can be effectively reduced, and the bright uniformity of the display panel is improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display panel power supply device, a manufacturing method, a power supply method and a display device. Background technique [0002] Display panels are used in various technical fields to form specific images. In related technologies, a display panel is provided with a plurality of sub-pixels distributed in an array structure, and combinations of the plurality of sub-pixels can form different images on the display panel. [0003] However, in the related art, multiple sub-pixels need to be connected to power supply terminals through wires. During the process of power supply terminals supplying driving voltages to multiple sub-pixels, the sub-pixels on the side away from the power terminal have a voltage drop due to wire resistance, resulting in On the display panel, the brightness of the sub-pixels close to the power supply terminal is greater than the brightnes...
