Abstract
The present disclosure provides a method for manufacturing a flexible touch control display screen. A TFT layer, an OLED display layer, and a film encapsulation layer are sequentially formed on the substrate. A first insulation layer, a first metal bridge, a second insulation layer, a second metal layer, and a protective layer are sequentially formed on the film encapsulation layer. By patterning the first photoresist layer with the use of a multi-transmittance mask, a first contact hole and a second contact hole having different depths are formed in the insulation layer.

A method for manufacturing a flexible touch control display screen, comprising:
- a step S20 of sequentially depositing a first insulation layer and a first metal layer on a film encapsulation layer, and using a first mask to carry out a first masking process for the first metal layer to form a first metal bridge on a surface of the film encapsulation layer;
- a step S30 of depositing a second insulation layer on a surface of the first metal bridge, wherein the second insulation layer covers the first metal bridge and the first insulation layer;
- a step S40 of using a first mask to carry out a first masking process for the second insulation layer to form a first contact hole and a second contact hole in the first insulation layer and the second insulation layer;
- wherein the first contact hole is disposed on the first metal bridge, the second contact hole is disposed on the film encapsulation layer and is positioned to correspond to a metal binding area on the film encapsulation layer, and a depth of the first contact hole is less than a depth of the second contact hole;
- a step S50 of depositing a second metal layer on a surface of the second insulation layer, and using a second mask to carry out a second masking process for the second metal layer to form at least two first electrodes, at least one second electrode, and a plurality of third electrodes on the second insulation layer, wherein the first electrodes intersect with the second electrode;
- and
- a step S60 of depositing a protective layer on a surface of the second metal layer, wherein the protective layer covers the second metal layer and the first insulation layer.
