Display screen, manufacturing method thereof, and electronic device

An electronic device, comprising a display screen, wherein the display screen comprises:

• a flexible substrate;
• a switch array layer disposed on the flexible substrate;
• an anode disposed on the switch array layer;
• a pixel definition layer disposed on the anode and comprising a plurality of opening areas;
• an organic light-emitting layer positioned in the opening areas;
• a cathode disposed on the organic light-emitting layer and the pixel definition layer, wherein the cathode is multiplexed as a first touch control electrode comprising a plurality of first touch control units;
• a second touch control electrode disposed on the cathode and comprising a plurality of second touch control units disposed at intervals;
• and
• a plurality of black matrices disposed on the second touch control electrode, wherein positions of the black matrices correspond to positions of the second touch control units.

A manufacturing method of a display screen, comprising following steps:

• manufacturing a switch array layer on a flexible substrate;
• manufacturing an anode, a pixel definition layer, an organic light-emitting layer, and a cathode on the switch array layer in sequence, and patterning the cathode to form a first touch control electrode;
• manufacturing a first inorganic layer, a color resist layer, an organic layer, and a second inorganic layer on the cathode in sequence;
• and
• manufacturing a conductive layer on the second inorganic layer, manufacturing a black matrix layer on the conductive layer, patterning the black matrix layer to form a plurality of black matrices, and using the black matrices to etch the conductive layer to retain the conductive layer having a position corresponding to the black matrices to obtain a second touch control electrode.
