Abstract

The invention discloses a display device and display method for teaching. The display device comprises a fixed base, a supporting plate, four external gear plates, two internal gear plates, and an annular writing board. The supporting plate is fixedly connected with the fixed base, and the four external gear plates are rotationally connected with the supporting plate. The four outer gear plates are located on the two sides of the upper end of the supporting plate and the two sides of the lower end of the supporting plate respectively, and the two inner gear plates are fixedly connected with the annular writing board. When the front face of the annular writing board has no writing space, the inner gear plates can be rotated downwards or upwards, so that the fully-covered front face of the annular writing board is rotated to the other side, and unwritten contents can be written on the rear face of the annular writing board. More contents can be written on the annular writing board, new contents can be added without wiping written contents, students can use the written contents for comparison conveniently, and convenience is brought to users.
