Display module

Abstract

A display module includes a first frame, a second frame, a first display panel, a second display panel, a pressure plate, a first adjusting screw, and a first compression spring. The first frame and the second frame are stacked along an adjustment axis. The first display panel and the second display panel are respectively disposed on the first frame and the second frame. The pressure plate is disposed on the same side of the first frame and the second frame. The first adjusting screw passes through the pressure plate and is screwed into the first frame. The first compression spring is sleeved on the first adjusting screw and abuts against the end of the pressure plate and the first adjusting screw away from the pressure plate. The first adjusting screw is adapted to be rotated to generate a preload in the first compression spring to push the pressure plate toward the first frame. The second frame and the pressure plate are provided with limiting structures to restrict the range of movement of the first frame along the adjustment axis and relative to the second frame.

Claims

1. A display module, comprising: A first frame and a second frame are stacked along an adjustment axis and each has a first side and a second side located on the same side and along the adjustment axis; a first display panel is disposed on the first frame; a second display panel is disposed on the second frame; a pressure plate is disposed on the same side of the first frame and the second frame and has a first plate surface facing the first side and the second side; a first adjusting screw passes through the pressure plate and is screwed into the first frame via the first side; and a first compression spring is sleeved on the first adjusting screw, wherein the first adjusting screw is adapted to be rotated to generate a preload in the first compression spring to push the pressure plate toward the first frame, and a limiting structure is provided on the second side of the second frame and the first plate surface of the pressure plate to limit the range of movement of the first frame along the adjustment axis and relative to the second frame.

2. The display module as described in claim 1 further includes: A second adjusting screw passes through the first frame and is screwed into the second frame; A second compression spring is fitted onto the second adjusting screw, wherein the second adjusting screw is adapted to be rotated to cause the second compression spring to generate an elastic force to maintain a distance between the first frame and the second frame along the adjusting axis.

3. The display module as claimed in claim 2, wherein the first adjusting screw has an abutting end away from the first frame, the first compression spring abuts the pressure plate and the abutting end, and the second compression spring abuts the first frame and the second frame.

4. The display module as claimed in claim 2, wherein the extension direction of the second compression spring is parallel to the adjustment axis, and the extension direction of the first compression spring intersects the extension direction of the second compression spring.

5. The display module as claimed in claim 1, wherein the limiting structure includes a stop portion and a limiting portion, the stop portion being disposed on the second side of the second frame, and the limiting portion being disposed on the pressure plate.

6. The display module as claimed in claim 5, wherein the limiting structure further includes a plurality of grooves disposed on the second side of the second frame, the grooves being spaced apart along the adjustment axis on the side of the stop opposite to the first frame, and the limiting portion on the pressure plate being adapted to move along the adjustment axis within the grooves.

7. The display module as claimed in claim 6, wherein the second frame has a plurality of protrusions defining the slots, each of the protrusions having an inclined surface opposite to the stop portion.

8. The display module as claimed in claim 1, wherein the limiting structure includes a stop, a limiting part, and a plurality of grooves, the stop and the grooves being disposed on the first plate surface of the pressure plate, the limiting part being disposed on the second side surface of the second frame, the grooves being spaced apart along the adjustment axis between the stop and the first frame, and the limiting part on the second frame being adapted to move along the adjustment axis within the grooves.

9. The display module as claimed in claim 1, wherein the pressure plate further has a second plate facing away from the first plate, the second plate having a plurality of scales arranged along the adjustment axis.

10. The display module as described in claim 1, further comprising: Multiple second adjusting screws pass through the first frame and are screwed into the second frame; The device includes a plurality of second compression springs respectively fitted onto the second adjusting screws; and a first linkage mounted on the second adjusting screws, wherein the second adjusting screws are linked to the first linkage and are adapted to be rotated synchronously to cause each of the second compression springs to generate a first elastic force to maintain a first gap between at least a portion of the first frame and at least a portion of the second frame along the adjusting axis.

11. The display module as described in claim 10, further comprising: Multiple third adjusting screws pass through the first frame and are screwed into the second frame; And multiple third compression springs, each sleeved on these third adjusting screws; A second linkage is mounted on the third adjusting screws, wherein the first frame has a first portion and a second portion, the first portion and the second portion being located on opposite sides of the first display panel, the second adjusting screws passing through the first portion, the third adjusting screws passing through the second portion, the third adjusting screws being linked to the second linkage and adapted to be rotated synchronously to cause each of the third compression springs to generate a second elastic force to maintain a second distance between the second portion of the first frame and the second frame along the adjusting axis, the second distance being different from the first distance.

12. A display module, comprising: A first frame and a second frame are stacked along an adjustment axis and each has a first side and a second side located on the same side and along the adjustment axis; a first display panel is disposed on the first frame; a second display panel is disposed on the second frame; a pressure plate is disposed on the same side of the first frame and the second frame and has a first plate surface facing the first side and the second side; a first adjustment screw passes through the pressure plate and is screwed into the first frame via the first side and has an abutting end away from the first frame; a first compression spring is sleeved on the first adjustment screw and abuts against the pressure plate and the abutting end respectively; a second adjustment screw passes through the first frame and is screwed into the second frame; and a second compression spring is sleeved on the second adjustment screw and abuts against the first frame and the second frame respectively.

13. The display module as claimed in claim 12, wherein a limiting structure is provided on the second side of the second frame and on the first plate surface of the pressure plate to limit the range of movement of the first frame along the adjustment axis and relative to the second frame.
