Abstract: A display module and a display device are provided. The display module includes a display panel, a flexible circuit board, and a printed circuit board. The display panel includes a bonding area. The flexible circuit board and the printed circuit board are electrically bonded and connected to the display panel in the bonding area, and are connected by a connector. The connector includes a first connection board and a second connection board. A side of the first connection board includes a groove including first pins. A side of the second connection board facing the first connection board includes second pins. The first pins and the second pins have a one-to-one correspondence. The second pins are plugged into the grooves, and are in contact with and electrically connected to the first pins; and a portion of at least one of the first pins is coated with a first insulating layer.

Abstract: An integrated teaching system for interaction and examination of ear acupoints includes a placement table, and a mounting plate rotatably mounted on the placement table by a first connecting shaft. Two ear acupoint models are symmetrically mounted on two sides of the mounting plate, respectively. The system further includes a support frame and a second connecting shaft fixed on the support frame, the second connecting shaft is connected to the first connecting shaft by a gear set, the second connecting shaft is rotatably connected to a mounting frame fixed on the placement table, an end of the support frame away from the placement table is inserted into a fixing sleeve and is slidable along the fixing sleeve, a lifting drive part is disposed in the support frame and connected to the fixing sleeve, and the lifting drive part is connected to the mounting frame by a transmission part.
