Samsung patents sliding phone frame with welded bars to support rollable screen

Samsung describes a device with a sliding housing that extends to reveal a flexible display. The screen has a flat section and a rolling section, supported by a grid-like plate and metal bars. Some bars are welded to the plate while others are glued, keeping the structure stable without blocking the screen.

Why it mattersThis design offers a specific mechanical solution for supporting flexible screens in sliding devices, which could influence future foldable or rollable phone designs.

In the filing’s own words

An electronic device is provided. The electronic device includes a first housing that includes a first cover, a sliding plate fixed to the first cover, and a body frame configured to slidably support the sliding plate, a second housing surrounding at least a portion of the first cover and connected to the body frame and configured to slidably support the first housing, wherein the first housing and the second housing are configured to switch a state between an extended state and a reduced state, a display that is connected to the sliding plate and transformable, wherein the display comprises a flat portion that maintains a flat shape and a rolling portion of which a shape is transformed, and the rolling portion comprises an exposed area that is visually exposed to an outside and a non-exposed area that is not visually exposed to the outside when the first housing and the second housing are in the extended state, a lattice plate connected to the display, wherein a plurality of holes is formed through the lattice plate, a plurality of first support bars connected to an exposed area of the display, a plurality of second support bars connected to a non-exposed area of the display, a first welded part configured to connect the plurality of first support bars to the lattice plate, and an adhesive layer configured to connect the plurality of second support bars to the lattice plate.

What exactly they claim (claim 1)

1. An electronic device comprising: a first housing comprising a first cover, a sliding plate fixed to the first cover, and a body frame configured to slidably support the sliding plate; a second housing surrounding at least a portion of the first cover and connected to the body frame and configured to slidably support the first housing, wherein the first housing and the second housing are configured to switch a state between an extended state and a reduced state; a display that is connected to the sliding plate and transformable, wherein the display comprises a flat portion that maintains a flat shape and a rolling portion of which a shape is transformed, and the rolling portion comprises an exposed area that is visually exposed to an outside and a non-exposed area that is not visually exposed to the outside when the first housing and the second housing are in the extended state; a lattice plate connected to the display, wherein a plurality of holes is formed through the lattice plate; at least one first support bar connected to the exposed area of the display; at least one second support bar connected to the non-exposed area of the display; a pair of first welded parts configured to connect the at least one first support bar to the lattice plate such that the pair of first welded parts does not overlap the display; and an adhesive layer configured to connect the at least one second support bar to the lattice plate, wherein the adhesive layer is not between the pair of first welded parts.
