Abstract

The description relates to display devices. One example can include a display having an active area surrounded by an inactive deadband. The example can also include a chassis, the display received in the chassis and secured to the chassis beneath the inactive deadband with adhesive. The example can further include a fastening assembly positioned below the inactive deadband and farther beneath the plane than the adhesive, where the fastening assembly creates a retention force between the display and the chassis.

First claim

The invention claimed is:

1. A device, comprising:
a display comprising a display protective layer and a plurality of display components, the display having an active area surrounded by an inactive deadband, where the active area and the inactive deadband lie in a plane;
a chassis, the display received in the chassis and secured to the chassis beneath the inactive deadband with adhesive; and
a fastening assembly extending into a cavity inside the chassis, the fastening assembly being positioned below the inactive deadband and farther beneath the plane than the adhesive, and further being secured to and laterally adjacent to the plurality of display components, the fastening assembly comprising a bracket that creates a retention force between the display and the chassis.

2. The device of claim 1 , wherein the chassis comprises a housing or wherein the chassis is positioned in a housing of the device.

3. The device of claim 1 , wherein the fastening assembly is stacked vertically below the adhesive.

4. The device of claim 1 , wherein the display protective layer extends along the plane and the adhesive extends between the display protective layer and the chassis.

5. The device of claim 1 , wherein the bracket comprises a biasing element that imparts a retention force that can be overcome to assemble or disassemble the display from the chassis.

6. The device of claim 5 , wherein the biasing element comprises a spring.

7. The device of claim 1 , wherein the fastening assembly comprises multiple fastening assemblies that are spaced apart from one another.

8. The device of claim 1 , wherein the bracket defines a dimple that is received in a recess defined by the chassis.

9. The device of claim 1 , wherein the device comprises a foldable computing device, a tablet, a smart phone, or a smart watch.

10. A device, comprising:
a display comprising a display protective layer, a plurality of display components, and a back plate, the display protective layer including an active area surrounded by a deadband;
a chassis defining a cavity located below the back plate and below the deadband; and
a fastening assembly extending into the cavity and laterally adjacent to the plurality of display components, the fastening assembly comprising a biasing element, where the biasing element creates a retention force between the chassis and the display to retain the display in the chassis.

11. The device of claim 10 , wherein the biasing element is secured to the chassis, and wherein the fastening assembly further comprises a bracket secured to the display and the biasing element comprises a spring that biases a plunger against the bracket to retain the fastening assembly in the cavity.

12. The device of claim 10 , wherein the biasing element is secured to the chassis, and wherein the fastening assembly further comprises a pin secured to the display and the biasing element interacts with the pin to retain the fastening assembly in the cavity.

13. The device of claim 12 , wherein the pin defines a narrow waist, and the biasing element comprises a spring wire which retains the pin in the cavity via the narrow waist of the pin.

14. The device of claim 10 , further comprising adhesive at a display-chassis interface below the deadband.

15. The device of claim 10 , wherein the biasing element is secured to the display.

16. A device, comprising:
a display comprising a display protective layer and a plurality of display components, the display having an active area surrounded by an inactive deadband;
a chassis, the display received in the chassis; and
first and second stacked securing mechanisms positioned beneath the inactive dead band that secure the display to the chassis, the second stacked securing mechanism being positioned laterally adjacent to the plurality of display components and comprising a biasing element that creates a retention force between the display and the chassis.

17. The device of claim 16 , wherein the first stacked securing mechanism is an adhesive and the second stacked securing mechanism comprises a bracket that includes the biasing element that imparts the retention force between the display and the chassis.

18. The device of claim 17 , wherein the biasing element is biased from the display and against the chassis.

19. The device of claim 16 , wherein the second stacked securing mechanism comprises a bracket that is separate from the biasing element and interacts with the biasing element to create the retention force.

20. The device of claim 16 , wherein the second stacked securing mechanism comprises a pin that is secured to the display and is engaged by the biasing element that is located on the chassis.
