The invention provides an In-cell touch display screen and a portable electronic product, aiming to solve problems in the prior art. In the existing In-cell touch display screen, a pressure sensing function is integrated on a backlight module. The backlight module has the defect of tensile deformation due to the performance of being not high temperature resistant, and the backlight module is easy to scratch due to low surface hardness, so that the processing difficulty is high, the yield rate is less than 70%, and the manufacturing cost is high. The In-cell touch display screen comprises a protective panel and a touch display module, and also comprises a pressure sensing functional chip. The pressure sensing functional chip is attached between the touch display module and the protective panel through an on-cell adhesive (OCA) layer. According to the In-cell touch display screen and the portable electronic product using the In-cell touch display screen, the manufacturing process is simpler, yield rate is higher, reaching up to over 90%, and the cost is lower.
