Abstract

A display assembly includes a liquid crystal display (LCD) frame, a printed circuit board (PCB), and a front housing. The LCD frame includes at least one LCD frame obround boss. The PCB includes at least one PCB obround slot, where the PCB obround slot is sized to be larger in length and diameter than the at least one LCD frame obround boss. The LCD frame is secured to a printed circuit assembly. The front housing includes a display opening and an elastomeric bezel positioned on the front housing, where the elastomeric bezel is configured to position a liquid crystal display within the display opening.

Claims

1. A display assembly, comprising:

a liquid crystal display frame including a liquid crystal display and at least one liquid crystal display frame obround boss;

a printed circuit board including at least one PCB obround slot, wherein the at least one PCB obround slot is sized to be larger in length and diameter than the at least one liquid crystal display frame obround boss,

the liquid crystal display frame being secured to the printed circuit board such that the liquid crystal display frame can float horizontally relative to the printed circuit board; and

a front housing including a display opening and an elastomeric bezel positioned on the front housing,

the elastomeric bezel being configured to position the liquid crystal display within the display opening; and

the sole connection between the liquid crystal display and the front housing being via the elastomeric bezel.

2. The display assembly of claim 1, wherein the liquid crystal display frame is fixed relative to the printed circuit board in a z-axis direction.

3. The display assembly of claim 2, wherein the liquid crystal display frame is fixed relative to the printed circuit board by a fastener.

4. The display assembly of claim 3, wherein the fastener is a screw that is screwed into the at least one liquid crystal display frame obround boss.

5. The display assembly of claim 4, wherein a head diameter of the screw is larger than a width of the at least one PCB obround slot.

6. The display assembly of claim 1, wherein the at least one liquid crystal display frame obround boss is positioned within the at least one PCB obround slot to secure the liquid crystal display frame to the printed circuit assembly.

7. The display assembly of claim 6, wherein a height of the at least one liquid crystal display frame obround boss is greater than a thickness of the printed circuit board.

8. The display assembly of claim 7, where a fastener head is prevented from seating on the printed circuit board because of the height of the at least one liquid crystal display frame obround boss.

9. A display assembly of a medical device, the display assembly comprising:

a liquid crystal display frame including a liquid crystal display and at least one liquid crystal display frame obround boss;

a printed circuit board including at least one PCB obround slot;

wherein the at least one PCB obround slot is sized to be larger in length and diameter than the at least one liquid crystal display frame obround boss,

the liquid crystal display frame being secured to the printed circuit board such that the liquid crystal display frame can float horizontally relative to the printed circuit board; and

wherein the at least one liquid crystal display frame obround boss is positioned within the at least one PCB obround slot to secure the liquid crystal display frame to the printed circuit board; and

wherein a height of the at least one liquid crystal display frame obround boss is greater than a thickness of the printed circuit board; and

a front housing including a display opening and an elastomeric bezel positioned on the front housing,

the elastomeric bezel being configured to position the liquid crystal display within the display opening; and

the only connection between the liquid crystal display and the front housing being via the elastomeric bezel.

10. The display assembly of claim 9, wherein a fastener head is prevented from seating on the printed circuit board because of the height of the at least one liquid crystal display frame obround boss.

11. The display assembly of claim 9, wherein the Liquid crystal display frame is fixed relative to the printed circuit board in a z-axis direction.

12. The display assembly of claim 11, wherein the Liquid crystal display frame is fixed relative to the printed circuit board by a fastener.

13. The display assembly of claim 12, wherein the fastener is a screw that is screwed into the at least one liquid crystal display frame obround boss.

14. The display assembly of claim 13, wherein a head diameter of the screw is larger than a width of the at least one PCB obround slot.
