Touch module, touch display module and manufacturing method of touch module

A touch display module, comprising:

• a touch module, comprising:
• a flexible base, wherein a thickness of the flexible base ranges from 25 micrometers to 100 micrometers;
• a moisture blocking film disposed on the flexible base, wherein the moisture blocking film has a first surface and a second surface opposite to the first surface, the first surface directly contacts the flexible base, and a thickness of the moisture blocking film ranges from 1 micrometer to 5 micrometers;
• and
• a touch structure disposed on the second surface of the moisture blocking film, comprising:
• a first conductive layer directly disposed on the second surface of the moisture blocking film;
• a first insulating layer disposed on the first conductive layer and covering the first conductive layer;
• a second conductive layer directly disposed on the first insulating layer;
• and
• a second insulating layer disposed on the second conductive layer and covering the second conductive layer;
• and
• a display module attached to the touch module, wherein the display module comprises a first substrate, a second substrate and a display medium layer disposed between the first substrate and the second substrate, and the touch structure is located between the display module and the moisture blocking film,
• wherein the touch structure has a touch electrode region and a peripheral circuit region, and an area of the moisture blocking film is greater than or equal to a sum of an area of the touch electrode region and an area of the peripheral circuit region in a top view direction of the touch module;
• wherein a water vapor transmission rate of the moisture blocking film is less than 5.0*10−4 g/(m2*day) at a temperature of 60° C. and a relative humidity of 90%;
• wherein the area of the moisture blocking film is greater than an area of the display module.
