OG exemplary drawing
 
1. A display screen, comprising:
a mother board;
at least one daughter board disposed opposite to the mother board;
a first conductive adhesive disposed between the mother board and the at least one daughter board, wherein a first adhesive force is formed between the first conductive adhesive and the at least one daughter board, wherein a material of the first conductive adhesive comprises a first matrix resin and a first conductor, and the first matrix resin comprises a polar group; and
a second conductive adhesive disposed between the first conductive adhesive and the mother board, wherein the second conductive adhesive is in direct contact with the first conductive adhesive, a second adhesive force is formed between the first conductive adhesive and the second conductive adhesive, and a third adhesive force is formed between the second conductive adhesive and the mother board, a material of the second conductive adhesive comprises a second matrix resin and a second conductor, and the second matrix resin comprises another polar group;
wherein both the first adhesive force and the second adhesive force are greater than the third adhesive force.
