## Abstract

An electronic display device, particularly product information and/or price information display device, which comprises a screen, and a housing or a housing casing, in which the screen is mounted, and a display device reinforcing structure, which is designed for reinforcing the display device with respect to external action of force.

## Claims

### Claim 1

An electronic display device, the display device being a product information and/or price information display device, the display device comprising:
a screen, and
a housing or a housing casing, in which the screen is mounted, and
a display device reinforcing structure, which is designed for reinforcing the display device with respect to external action of force,
wherein the display device reinforcing structure comprises a space-filling reinforcing element, which fills an inner space of the housing or the housing casing, which lies behind the screen in a reinforcing manner at least in certain areas.

### Claim 2 (depends on 1)

The display device according to claim 1, wherein the display device reinforcing structure comprises a front-side reinforcing element, which grips the screen from its intended viewing side at least in certain areas.

### Claim 3 (depends on 2)

The display device according to claim 2, wherein the front-side reinforcing element is designed as a frame and grips the screen in a frame-shaped manner.

### Claim 4 (depends on 3)

The display device according to claim 3, wherein the frame comprises a viewing window.

### Claim 5 (depends on 1)

The display device according to claim 1, wherein the display device reinforcing structure comprises a rear-side reinforcing element, which grips the screen directly at its rear side, which faces away from the intended viewing side.

### Claim 6 (depends on 5)

The display device according to claim 5, wherein the rear-side reinforcing element is constructed as a plate and connected to the rear side of the screen in a materially bonded manner.

### Claim 7 (depends on 6)

The display device according to claim 6, wherein the plate is realized as a multilayer structure.

### Claim 8 (depends on 1)

The display device according to claim 1, wherein the space-filling reinforcing element is realized by at least one spatial structure from the group listed below, namely:
a honeycombed spatial structure,
a rib-like spatial structure,
a wave-like spatial structure,
a column-shaped spatial structure,
a spiral spatial structure.

### Claim 9 (depends on 1)

The display device according to claim 1, wherein the space-filling reinforcing element is arranged at least in certain areas behind the screen and supports the screen at the rear side thereof towards the housing or towards the housing casing.

### Claim 10 (depends on 1)

The display device according to claim 1, wherein the space-filling reinforcing element is designed as a constituent of the housing or the housing casing.

### Claim 11 (depends on 1)

The display device according to claim 1, wherein the housing or the housing casing comprises a fastening structure at its housing rear side, which surrounds the screen at the rear side, which fastening structure is constructed in such a manner that the display device can be fastened to a shelf edge stripes.

### Claim 12 (depends on 11)

The display device according to claim 11, wherein at least a part of the fastening structure is designed as a battery compartment cover.

### Claim 13 (depends on 6)

The display device according to claim 6, wherein the rear-side reinforcing element is laminated to the rear side of the screen.

### Claim 14 (depends on 7)

The display device according to claim 7, wherein the plate is realized as a sandwich structure.

### Claim 15 (depends on 9)

The display device according to claim 9, wherein the space-filling reinforcing element is arranged adjacently to electronics provided behind the screen.
