A display device is disclosed. The display device includes a housing, at least one roller positioned inside the housing, a display unit including a display panel and a module cover having at least one apron, of which at least a portion is connected to each other, and a driver including a motor assembly, an upper bar coupled to an upper part of the display unit, and at least one support portion having one side coupled to both ends of the upper bar and the other side coupled to the motor assembly and moving up and down the upper bar. Both ends of the at least one apron bend in a forward direction.

A display device is disclosed. The display device includes a housing, a plurality of rollers positioned inside the housing, a display unit including a display panel and a module cover having at least one apron, of which at least a portion is connected to each other, and a driver including a motor assembly, an upper bar coupled to an upper part of the display unit, and at least one support portion having one side coupled to both ends of the upper bar and the other side coupled to the motor assembly and moving up and down the upper bar. The display panel and the module cover are in a first state in which they are wound around the roller or a second state in which they are unwound from the roller, contact each other, and are exposed to the outside of the housing.

A shrink sleeve apparatus is disclosed herein that includes a shrink sleeve applicator, a downstream heat shrink station, and a horizontal conveyor having side-by-side rollers that have a circumscribing outer portion with at least one high traction segment and at least one low traction segment. A method of applying a shrink sleeve to an article is disclosed that includes providing a conveyor having rollers as disclosed herein, positioning the rollers such that low traction segments of the rollers support the article as it passes a shrink sleeve applicator, which applies a shrink sleeve. The high traction segments of the rollers do not interfere with sleeve application. As the conveyor moves the article and sleeve through a downstream heat shrink zone, the rollers are rotated so that the high traction segments contact the article and sleeve to assure rotation of the article and sleeve during heat shrink.
