Mobile terminal
Disclosed is a mobile terminal including a first frame, a second frame sliding from the first frame in a first direction or in a second direction, a slide frame movable in the first direction or in the second direction with respect to the second frame, a flexible display unit including a third region bent while surrounding the second frame, and a rolling plate having one surface, wherein the flexible display unit is attached to said one surface of the rolling plate, wherein the rolling plate includes a plurality of support bars extending in a third direction perpendicular to the first direction and arranged side by side in the first direction, and each connector positioned between adjacent two of the plurality of support bars and having a thickness less than a thickness of the support bar, wherein the support bar and the connector are manufactured integrally of the same material.
1. A mobile terminal comprising:
a first frame;
a second frame slidably-movable with respect to the first frame in a first direction or in a second direction opposite to the first direction;
a slide frame slidably-movable with respect to the second frame in the first direction or in the second direction;
a flexible display including a first region coupled to the first frame, a second region coupled to the slide frame, and a third region positioned between the first region and the second region, wherein the third region is curved around the second frame; and
a rolling plate comprising a first surface attached to the flexible display, a plurality of support bars extending in a third direction perpendicular to the first direction and arranged side by side in the first direction, and connectors such that each connector is positioned between two adjacent support bars among the plurality of support bars, wherein a thickness of each connector is less than a thickness of a support bar among the plurality of support bars, wherein the support bar and each connector comprise a same material.
2. The mobile terminal of claim 1 , wherein each connector further comprises a rolling hole extending in the third direction.
3. The mobile terminal of claim 2 , wherein rolling holes are each arranged to be staggered with a rolling hole defined in a neighboring connector in the third direction.
4. The mobile terminal of claim 1 , wherein the thickness of a connector varies in the first direction such that a portion of the connector adjacent to the support bar has a greater thickness than a central point of the connector between the two adjacent support bars.
5. The mobile terminal of claim 4 , wherein the thickness of the connector varies such that the connector forms a curved face protruding in a direction of a second surface of the rolling plate, wherein the curved face comprises a predetermined curvature wherein the second surface of the rolling plate faces an opposite surface of the first surface of the rolling plate.
6. The mobile terminal of claim 5 , wherein the support bar further comprises:
a first protrusion protruding in a direction of the second surface of the rolling plate; and
a second protrusion protruding in a direction of the first surface of the rolling plate, wherein the second protrusion is smaller than the first protrusion.
7. The mobile terminal of claim 1 , wherein the second frame further comprises a side portion located at an end of the second frame in the third direction and a slide rail located inward with respect to the side portion,
wherein the rolling plate further comprises:
a first expanded side portion extending from an end of the support bar in a direction of a second surface of the rolling plate; and
a slide hook protruding from a position of the first expanded side portion, wherein the slide hook is spaced apart from the flexible display.
8. The mobile terminal of claim 7 , wherein an end of the connector is disposed to be spaced apart from the first expanded side portion.
9. The mobile terminal of claim 7 , further comprising a second expanded side portion forming a step with respect to the first expanded side portion, wherein the second expanded side portion extends in the first direction or in the second direction.
10. The mobile terminal of claim 7 , wherein the rolling plate is integrally formed based at least in part on injection molding.
11. The mobile terminal of claim 7 , wherein the first expanded side portion has a width in the first direction that is reduced as the first expanded side portion extends in a direction away from the flexible display.
12. The mobile terminal of claim 1 , wherein the rolling plate further comprises a rolling sheet located between the support bar and the flexible display,
wherein the rolling sheet further comprises a plurality of rolling holes extending in the third direction between the plurality of support bars.
