Description

Display module Technical Field The present invention relates to a display technology, and more particularly, to a display module capable of displaying a depth of field effect. Background The display module with two display panels stacked at a specific interval can generate a display effect with depth of field. In the prior art, the distance between two display panels is achieved by disposing a spacer (spacer) between them and locking them. However, the aforementioned gaskets can only produce one depth of field effect. If the depth of field is to be changed, the whole module must be disassembled and the gaskets with different thicknesses must be replaced, so that the reworking time is long, and the damage risk of the display panel in the disassembly and assembly process is increased.
