Micro light emitting diode display panel with option of choosing to emit light both or respectively of light-emitting regions

A micro light emitting diode display panel comprises:

• a backplane comprising a plurality first electrode lines and a plurality of second electrode lines, wherein the plurality of first electrode lines and the plurality of second electrode lines define a plurality of sub-pixel regions arranged in an array form;
• and
• a plurality of micro light emitting diode chips disposed on the backplane and respectively located in the sub-pixel regions, wherein each of the plurality of micro light emitting diode chips has a first electrode, a plurality of second electrodes and a plurality of light-emitting regions, the first electrode is bonded to one of the plurality of first electrode lines, and the plurality of second electrodes are bonded to one of the plurality of second electrode lines, and each of the plurality of light-emitting regions is defined by the first electrode and one of the plurality of second electrodes to emit light,
• in a defect sub-pixel region, the electrical connection between one of the plurality of second electrodes and the corresponding one of the plurality of second electrode lines is cut to isolate;
• and
• wherein the plurality of second electrodes comprise four second electrodes, and the four second electrodes surround the first electrode, and the plurality of light-emitting regions comprise four light-emitting regions.
