Abstract

The utility model discloses an ultrathin display module based on rib position support, which belongs to the technical field of household appliance display screens, wherein a hard sheet is fixedly connected on the upper surface of a circuit board of the display module, and a through hole is formed in the hard sheet at a position corresponding to the touch display key, and the through hole is separated from the through hole by a rib. The light guide plate is arranged in the through hole of the hard thin plate, the rib positions limit the light guide plate and block light rays between the adjacent light guide plates, and the membrane is arranged above the hard thin plate. The hard sheet is divided into a sheet body and a rib position connected with the sheet body, and the rib position and the sheet body are integrally formed. The utility model adopts the hard sheet to replace the foam layer, is not easy to deform, and better supports and limits the light guide plate. The size of the rib position can be extremely narrow, so that gaps among touch display keys are reduced, and the panel display is more attractive. The hard thin plate is integrally formed, and can be manufactured into different thicknesses in different areas, so that the thickness requirements of different areas are met.
