DISPLAY PANEL FOR COMPENSATING NEGATIVE POWER SUPPLY VOLTAGE, DISPLAY MODULE AND MOBILE DEVICE INCLUDING THE SAME

摘要

A display panel including: a cathode electrode formed in a cathode region of the display panel, the cathode electrode entirely covering an active region of the display panel a plurality of pixel units in columns and rows in the active region of the display panel; a ring-shaped edge negative voltage line formed in a ring-shaped edge portion of the cathode electrode configured to supply a negative power supply voltage to the cathode electrode; and a plurality of compensation negative voltage lines connected to the ring-shaped edge negative voltage line, the compensation negative voltage lines extending along a column direction of the display panel and arranged along a row direction of the display panel.
