Abstract: A display device includes a display panel, a middle frame, an annular retaining edge and a cover module. One side of the middle frame is provided with the annular retaining edge around a through hole, a receiving space communicating with the through hole is enclosed by the annular retaining edge and the middle frame, and the display panel is limited in the receiving space; and the cover module includes a protective cover covering a side, with the annular retaining edge, of the middle frame, a first buffer is placed between the protective cover and the display panel, and the protective cover fixes the display panel in the receiving space in a pressing manner through the first buffer. The protective cover fixes the display panel in a first groove in a pressing manner through the first buffer.

Abstract: The present application provides an infrared touch display screen, including a frame, a display panel assembly, a light-filter strip and a circuit board assembly. The display panel assembly includes a protective layer, the circuit board assembly includes a circuit board and infrared lamp tubes arranged on the circuit board, the frame includes a first portion for mounting the light-filter strip and a second portion for mounting the circuit board assembly, the first portion is located at a front side of the protective layer, the second portion is located outside the protective layer and the first portion; the circuit board corresponds to a position of the protective layer in a front-back direction, the infrared lamp tubes correspond to a position of the light-filter strip in the front-back direction, and an extending direction of the infrared lamp tubes is parallel to the protective layer.
