Abstract
The present application discloses a pressure detection structure and a terminal device. The pressure detection structure includes a cover, a display screen, a pressure sensor and a middle frame, the display screen and the cover being sequentially stacked in the middle frame from bottom to top; wherein: the pressure sensor is fixed to the display screen; the display screen includes a lower glass layer, an LED light emitting layer and an upper glass layer which are sequentially stacked from bottom to top; and the pressure sensor is positioned beneath the lower glass layer. Thus, the tolerance to be controlled mainly lies in the thickness of the gap layer inside the display screen, and the flatness of the pressure sensor. Hence, the assembling tolerance is reduced, and the stability, reliability and consistency of pressure detection by the terminal device are improved.
