Back plate and manufacturing method thereof, method for bonding chip, and display device

A method for manufacturing a back plate, comprising:

• providing a base plate;
• and
• forming a plurality of conductive connecting tubes on the base substrate, wherein one end of each of the conductive connecting tubes is connected to the base substrate, and a side wall of each of the conductive connecting tubes is provided with an opening penetrating the side wall;
• wherein prior to forming the plurality of conductive connecting tubes on the base substrate, the method further comprises:
• forming a thin film transistor and a common electrode on the base substrate;
• and forming the plurality of conductive connecting tubes on the base substrate comprises:
• forming the plurality of conductive connecting tubes, wherein the plurality of conductive connecting tubes comprises a first conductive connecting tube disposed on a side of the thin film transistor away from the base substrate, and the first conductive connecting tube is electrically connected to the thin film transistor, wherein the plurality of conductive connecting tubes further comprises a second conductive connecting tube disposed on a side of the common electrode away from the base substrate, and the second conductive connecting tube is electrically connected to the common electrode.

A method for bonding a chip, comprising:

• providing a back plate, wherein the back plate comprises a base substrate and a plurality of conductive connecting tubes disposed on the base substrate, one end of each of the conductive connecting tube being connected to the base substrate, and a side wall of each of the conductive connecting tube being provided with an opening penetrating the side wall;
• inserting an electrode of the chip into a corresponding conductive connecting tube from an end of the conductive connecting tube away from the base substrate;
• and
• heating the conductive connecting tube and the chip, so that the electrode of the chip is electrically connected to the conductive connecting tube.
