Projection arrangement and formation of image module thereof

The utility model provides a formation of image module, includes display element, prism and image gearshift. Display element includes the active display face. The prism includes the optical surface. The image gearshift sets up between display element and prism. The image gearshift includes optical element, holds carrier seat, base and at least unanimous hydraulic buffer stop. Optical element setsup on holding carrier seat. The relative base of at least actuator drive optical element swing, the active display face is first distance to optical element's distance, and the normal line at active display face center is the reference line, and in the line segment of the front projection shadow of an at least actuator on the reference line, neighbouring display element's extreme point is the reference point, and reference point to optical element's distance is A second distance, and to hold edge and the distance between the optical element that carrier seat is close to the prism be the interval, first distance is lig
