Description

Technical Field

[0001] This invention relates to an electronic display device having a signal indicating device. Background Technology

[0002] For example, electronic display devices are used in sales areas to display information about the products offered. Typically, a large number of electronic display devices are used here. To better perceive information and / or draw attention to specific information in the presence of numerous electronic display devices, these devices are equipped with signal indicating devices. For example, WO2019076447A1 discloses an electronic price and / or product display device having a reflective screen for displaying information and a signal indicating device for indicating the internal state or state change of the display device in a visually perceptible manner, superimposed on the displayed information, in the direction of direct eye contact towards the screen. This electronic price and / or product display device achieves this by means of a light signal to draw attention to itself. However, it has been shown that if the observer has not, in any case, directly looked at the corresponding electronic price and / or product display device, the emitted light signal is usually not perceived. For example, if the electronic price and / or product display device is fixed particularly high or particularly low on a shelf, it is often ignored despite the signal being emitted. To still increase the chances of drawing attention to the location, a significantly stronger light signal is required, which necessitates increased energy demands. Since electronic price and / or product display devices are typically configured to operate on batteries, this increased energy demand is accompanied by increased maintenance requirements, as batteries must be replaced or recharged at more frequent intervals.

[0003] Therefore, the object of the present invention is to provide an electronic display device that overcomes the above-mentioned problems. Summary of the Invention

[0004] The objective is achieved by the electronic display device according to claim 1. Therefore, the subject of the invention is an electronic display device having a screen for displaying information, a housing for housing the screen, and a transparent screen cover covering the screen, wherein, when viewed along the normal direction of the screen, the screen cover extends beyond the screen and beyond the housing housing housing the screen, and wherein the screen cover is configured to emit light in a direction substantially parallel to the extension of the screen.

[0005] Light can be emitted from the screen cover, especially at the edge surface (or edge area) of the screen cover, so that the light emitted by the electronic display device can be well perceived not only from the front (i.e. when viewed from the front), but also from the side, from above and / or from below.

[0006] Therefore, an electronic display device is provided that can emit light in a particularly perceptible manner for purposes such as signal indication or attracting attention.

[0007] Therefore, an advantage arising from the measures of the present invention is that it provides an electronic display device for generating signals that are particularly well visually perceptible.

[0008] Other particularly advantageous designs and modifications of the invention are derived from the dependent claims and the following description.

[0009] The screen is preferably flat. The screen cover is also preferably flat. Therefore, the mentioned direction applies across the entire screen plane, which is the screen plane as seen by the observer (front view). However, curved screens and / or curved screen covers can also be used, in which case the mentioned direction should be interpreted with reference to a point on the screen. In the case of a flat screen, the normal direction runs substantially opposite to the line of sight of an observer viewing the electronic display device from the front.

[0010] Therefore, electronic display devices are configured to emit light substantially parallel to the screen plane, that is, substantially transverse to the normal direction.

[0011] The screen cover has a bottom surface facing the screen and a top surface further away from the screen than the bottom surface. Therefore, along the normal direction, the screen cover first has a bottom surface and then a following top surface. The bottom surface can be directly abutted against the screen or spaced apart from it. Furthermore, the screen cover is defined on its circumferential side by edge surfaces or side surfaces extending between the bottom and top surfaces. Thus, the edge surfaces form the lateral boundaries of the screen cover. Here, the edge surfaces can have different shapes. For example, they can therefore be flat, particularly oriented normal to the bottom surface or angled to the bottom surface. However, the edge surfaces can also be, for example, rounded or even wavy, etc.

[0012] To ensure that light can propagate to the observer undisturbed, the edge surfaces of the screen cover are independent even if the observer is not directly standing in front of the screen. In directions parallel to the screen or the outer screen surface, the screen cover is at least partially, and preferably completely, unenclosed. Therefore, the independent edge surfaces of the screen cover are at least partially, and preferably completely, not enclosed by adjacent structures, and particularly preferably not covered or obscured by any structure.

[0013] Therefore, the electronic display device is configured such that the edge surface of the screen cover is visible from a viewing direction parallel to the screen. Consequently, light emitted from the screen cover is also well visible at said edge surface in a viewing direction parallel to the screen.

[0014] The electronic display device is preferably configured as an electronic product and / or price display, particularly as an electronic price tag, also known as an Electronic Shelf Label (ESL). Therefore, the displayed information is preferably product and / or price information. According to the invention, this information can be supplemented by emitted light. Therefore, the emitted light can also be utilized without displaying product and / or price information.

[0015] The electronic display device is preferably configured to be fixed to the shelf rails.

[0016] The screen overlay is transparent to the extent that the screen behind it or any information that may be displayed on the screen is visible.

[0017] The screen cover can be made of or have glass. Tempered glass, especially tempered aluminosilicate glass, is preferred.

[0018] The screen cover is preferably made of a polymer, particularly a transparent thermoplastic polymer, or has a polymer composition. Preferred materials include, for example, polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), thermoplastic polyurethane or thermoplastic polyurethane (TPU), and / or polyallyl diethylene carbonate (PADC; also known as CR-39). Polymethyl methacrylate (PMMA, also called acrylic glass) is particularly preferred. Therefore, the screen cover preferably has polymethyl methacrylate, and is particularly preferably made of polymethyl methacrylate.

[0019] The screen cover is configured to redirect or conduct incident light to a desired location, particularly towards the edge surface of the screen cover. Therefore, the screen cover can be understood, at least partially or entirely, as a light guide. Thus, the screen cover essentially provides a planar light guide.

[0020] The electronic display device is preferably configured such that a screen cover completely covers the screen. Particularly preferably, the screen cover covers the screen, that is, it extends beyond the edge boundary of the screen and extends beyond that boundary. This measure ensures that the screen is well protected against damage. Simultaneously, the location of the lateral light emission is spatially separated from the screen or its edge boundary, thus making it particularly easy to perceive.

[0021] Furthermore, the electronic display device is preferably configured such that a screen cover covers at least a portion of the housing. This measure achieves the illumination of a lateral area of ​​the housing adjacent to the screen cover, thereby creating an attractive lighting effect there. In visual perception, the illuminated area of ​​the housing widens the light-emitting area of ​​the screen cover. Therefore, the illuminated surface increases. If necessary, the lighting effect can also be achieved in the area of ​​the housing covered by the screen cover.

[0022] According to the first embodiment, the screen cover protrudes to the edge of the housing in at least one direction, preferably in two directions, particularly in two opposing directions, or in three directions, especially preferably in all four directions. This measure allows the emitted light to be perceived even in a very flat line-of-sight direction, i.e., when an observer is directly below the electronic display device and looking at the downward-oriented edge region of the electronic display device. Therefore, according to the embodiment, the screen cover preferably covers the entire screen and the housing adjacent to the screen.

[0023] According to the second embodiment, the screen cover extends beyond the edge of the housing in at least one direction, preferably in two directions, particularly in two opposing directions, or in three directions, especially preferably in all four directions. This measure allows the emitted light to be perceived even when the electronic display device is viewed from its rear. Therefore, according to this embodiment, the screen cover preferably covers the entire screen and housing.

[0024] According to the third, particularly preferred embodiment, the screen cover does not protrude to the edge of the housing in at least one direction, preferably in two directions, particularly in two opposing directions, or in three directions, particularly preferably in all four directions.

[0025] Therefore, the electronic display device is preferably configured such that the housing protrudes below the screen cover.

[0026] With this measure, the housing can be illuminated via the screen cover in areas where the screen cover protrudes or protrudes. Therefore, the electronic display device can be particularly conspicuously illuminated, where light is perceptible especially from lateral directions (e.g., above, below, left, and right). Thus, this measure allows for the provision of electronic display devices with particularly well-perceptible light emission.

[0027] It is also possible to achieve a combination of the three mentioned embodiments, such that the screen cover protrudes to or beyond the edge in one direction, while the housing protrudes at the screen cover in another direction. However, preferably, all edges of the screen cover are implemented according to one of each of the mentioned embodiments.

[0028] According to one aspect of the invention, the screen cover has an edge surface, and the screen cover is configured to emit light at at least one face segment of the edge surface, preferably over the entire edge surface.

[0029] The screen cover is preferably configured to emit light only in a portion of the edge surface of the screen cover.

[0030] The edge surface is preferably divided into multiple partial surfaces, each of which corresponds to a segment of the circumference of the bottom surface. Here, the bottom surface is preferably configured as a square or a rounded square. The screen cover can be configured to emit light via its edge surface at exactly one partial surface, or at exactly two partial surfaces, or at exactly three partial surfaces, or at exactly four partial surfaces, or at all partial surfaces (if more than four partial surfaces exist).

[0031] The screen cover may also have a reduced light transmittance at at least one side compared to another side, or be configured to be opaque at at least one side.

[0032] According to one embodiment, at least a portion of the edge surface, preferably at least one portion, has a reflector area, wherein the reflector area is configured to reflect light guided to the edge surface by the screen cover back into the screen cover. The reflector area can be implemented, for example, by a mirror coating (e.g., a metallic coating) or a color layer (e.g., a white color layer). This measure specifically prevents light from escaping at at least one undesirable location or area. Simultaneously, with the same energy requirement, light emitted at the location designated for light emission appears brighter. Therefore, energy requirements can be optimized. The directional light emission also allows for targeted highlighting of specific areas or environments of the screen cover. For example, identification marks on the screen or particularly on the housing can thus be made visible or targetedly illuminated, which optimizes maintenance. Directional light emission can also be used to visually attract attention only when viewed from one direction.

[0033] According to another aspect, the screen cover has a diffuser area at its edge surface for emitting scattered light, particularly in a direction substantially parallel to the screen.

[0034] Here, "in a direction parallel to the screen" essentially means that the average direction of the diffusely emitted light extends as parallel to the screen as possible.

[0035] The diffuser region preferably has a scattering center, such as an air space, particularly a bubble. This scattering center can be created, for example, by machining (particularly cutting), by thermal processing, thermomechanical processing, or chemical processing. A well-defined diffuser region can also be produced by engraving, particularly by laser engraving.

[0036] Therefore, the diffuser region can be understood as a region with an increased number of scattering centers compared to the rest of the screen covering. Here, considering volume, this number can be increased by 10 times, preferably 100 times, and particularly preferably 1000 times.

[0037] Furthermore, the screen cover can have a diffuser area, specifically positioned to cover the screen, for emitting diffused light substantially in a direction normal to the screen. This measure allows for targeted illumination of the screen, thereby optimizing the use of light so that information displayed on the screen is particularly well perceived.

[0038] Therefore, the screen cover is preferably configured to emit light in a surface manner, particularly toward the screen.

[0039] The screen can be configured as a transflective or reflective screen. The electronic display device can be configured to backlight the screen from the inside or from the rear, i.e., from the side of the screen facing away from the screen cover. With the help of the screen cover, light passing through the screen is primarily guided to the edge surface of the screen cover and emitted there. Therefore, the existing light can be optimally utilized.

[0040] The screen is preferably configured as a reflective screen. A reflective screen allows the displayed information to be well-readable even with minimal incident light. This incident light can be provided by ambient light from a more distant environment of the display device. However, it can also be provided by light generated within the display device itself and propagating within the screen cover. Therefore, even in the absence of ambient lighting, the information displayed on the screen remains easily readable.

[0041] According to one aspect of the invention, an electronic display device has at least one light source for emitting light, the light source being configured to illuminate a screen cover.

[0042] As a light source, different types of light-emitting mechanisms can be used, such as incandescent lamps, gas discharge lamps, or other electronic light-emitting mechanisms or electronic light sources. Preferably, at least one light-emitting diode (LED) is used as the light source. Particularly preferably, the light source, especially the LED, is implemented by positioning it on a circuit board (also known as a "printed circuit board," or PCB for short). If the screen also has active (background) illumination, the light source is additional to this arrangement.

[0043] The light is, at least but not limited to, light that is visible to humans.

[0044] In order to control the light source, electronic display devices preferably have a control level.

[0045] In addition, electronic display devices can have energy storage, particularly batteries or accumulators, and / or be configured to supply power via an external power supply (e.g., based on radio or preferably wired).

[0046] The control level controls the power delivery of the light source.

[0047] Electronic display devices can be configured such that a light source directly illuminates or lights the screen cover.

[0048] However, electronic display devices can also have a light deflection structure, particularly separate from the screen cover, configured to direct light from a light source toward the display device. The light deflection structure can, for example, include a light guide, a mirror, etc.

[0049] An electronic display device can be configured to illuminate a screen cover at one of its sides corresponding to the normal direction, particularly in the edge region of the screen cover, preferably illuminating the edge surface of the screen cover. According to this embodiment, the electronic display device has a light source arranged and positioned to illuminate the screen cover in a direction parallel to the screen, preferably via the edge surface of the screen cover.

[0050] According to a preferred embodiment, the electronic display device is configured to illuminate the screen cover with light from a light source on the side of the screen cover facing the screen, particularly on the side of the screen cover parallel to the screen's extension. This measure has proven particularly advantageous because the light passing through the screen cover is thus uniformly distributed in a planar pattern. Consequently, the electronic display device is particularly well-identifiable from many different viewing directions.

[0051] The light source is preferably coupled to the screen cover in a light-guiding manner. Particularly preferably, the light source is configured as a light-emitting diode on a circuit board (PCB) and coupled to the screen cover from there in a light-guiding manner.

[0052] The screen cover preferably has a light distribution area at the light entry area for light entry, the light distribution area being configured to distribute light radiation within the screen cover, particularly toward the edge region of the screen cover. The light distribution area can be achieved, for example, by means of material grooves (such as notches), wherein the grooves can be filled with materials having different refractive indices, and / or configured as light scattering areas.

[0053] The light distribution area preferably has an inward concavity and / or an outward convexity.

[0054] Particularly preferably, the light distribution area is also configured to mechanically couple the screen cover to the housing. Therefore, the light distribution area can, for example, have pins that are mechanically connected to the housing and through which the light source is coupled to the screen cover in a light-guiding manner.

[0055] The light source is preferably covered by a screen cover. In addition to the advantages mentioned above, this measure also provides protection for the light source from mechanical loads and contamination.

[0056] The light source is preferably located inside the housing.

[0057] Furthermore, it has proven advantageous for electronic display devices to have at least two light sources, particularly positioned at opposite edges of the screen. This achieves uniform illumination, and consequently, uniform recognizability of the electronic display device from different viewing angles. Thus, one light source can be replaced by two weaker light sources, thereby providing improved recognizability with the same or reduced energy consumption. It is also possible to have more than two light sources arranged around the screen at different locations, particularly evenly distributed.

[0058] Different light sources can be controlled jointly or independently. Therefore, the control level is preferably configured to control different light sources jointly and / or independently and / or in groups.

[0059] The control level can also be configured to control the light source based on information and / or screen data to be displayed on the screen, or to control the light source independently of the screen.

[0060] According to another aspect of the invention, the light source and the screen cover form a screen lighting device for illuminating the screen.

[0061] Therefore, the screen cover undertakes both the illumination of the screen and the emission of visually perceptible light signals, making these signals perceptible from various viewing directions, even from those viewing directions from which the screen or its content cannot be perceived. This achieves both functions simultaneously through reduced construction costs, material requirements, and consequently, lower complexity. Thus, this measure provides an optimized electronic display device for displaying information using various visual formats.

[0062] Furthermore, these measures ensure good perceptibility of information displayed on the screen, even in poorly lit or dark rooms.

[0063] According to one embodiment, the electronic display device is configured to illuminate only a portion of the screen and / or housing via a screen cover, particularly illuminating only the portion of the screen and housing that protrudes from it. Therefore, an observer's focus can be directed to the electronic display device, and further to a specific area of ​​the screen, and consequently to specific information on the screen. For example, the text "AKTION" can thus be displayed in a corner of the screen, and the screen area displaying the text and the surrounding edge, and consequently the surrounding housing, are illuminated in red. Thus, an observer searching for the promotional item can see where the promotional item is located from a distance (e.g., when they are looking longitudinally down an aisle and essentially only see the side of the electronic display device), because the item is highlighted by the characteristically illuminated corner. If the observer now approaches the electronic display device, the thus illuminated screen and the displayed information become identifiable, and their gaze can be focused on the illuminated screen area.

[0064] Therefore, the screen cover can be configured as a fan-shaped and / or have a fan-shaped diffuser area.

[0065] Preferably, a separate light source is set for the corresponding fan-shaped or diffuser area.

[0066] The control level is configured to operate individual and / or group individual light sources.

[0067] According to another aspect of the invention, the electronic display device is configured to manipulate a light source based on the detection of an event, preferably electronic communication, and in particular a search request. This is achieved through a control level. The search request can be received radioly and cause, for example, red light to be emitted from the edge of the display device, so as to make it easier to find, for example, in a long shelf aisle.

[0068] In summary, the light-guiding screen cover, together with the light source, forms a signal indication device for the display device, used for indicating light signals in the main lateral directions.

[0069] Electronic display devices can have an input stage, a communication stage, and / or a detection stage. The input stage is configured to detect user interactions, such as buttons that actuate the electronic display device. The communication stage is preferably configured for wireless, particularly radio-based, communication. The detection stage is configured to detect events in the environment of the electronic display device. Therefore, electronic display devices can, for example, have a distance sensor and / or a camera for detecting the presence of people in the environment of the electronic display device, or a temperature sensor or humidity sensor, etc.

[0070] Therefore, the event could be, for example, the detection of user interaction. The event could be communication, particularly a search request regarding the electronic display device and / or objects associated with the electronic display device, especially the offered products. It could also be the detection of events in the environment of the electronic display device. The electronic display device is preferably configured to communicate directly or indirectly with an external detection device, particularly a camera, wherein the camera is configured to detect the environment of the electronic display device and report the detection to the electronic display device. Detected temperature or humidity, or reaching a threshold, could also generate such an event.

[0071] Once an event occurs, the light source can be activated or deactivated, or its light intensity or color can be affected electronically.

[0072] Finally, it should be generally mentioned that the electronic devices discussed naturally possess electronic components. These electronic components can be discrete, constructed through integrated electronic components, or a combination of both. Microcomputers, microcontrollers, application-specific integrated circuits (ASICs), combined with analog or digital electronic peripherals where necessary, can also be used. Many of the mentioned functions of the device—which, where necessary, cooperate with hardware components—are implemented by means of software executing on the processor of the electronic device. Devices configured for radio communication typically have an antenna configuration as part of a transceiver module for transmitting and receiving radio signals. The electronic devices can also have an internal power supply, which can be provided, for example, by means of a replaceable or rechargeable battery. The devices can also be wired, powered either by an external power source or by means of Power over LAN (PoE).

[0073] The description and other aspects of the invention are derived from the accompanying drawings discussed below. Attached Figure Description

[0074] The invention will now be explained in more detail with reference to the accompanying drawings and embodiments; however, the invention is not limited thereto. Here, in different drawings, the same parts are given the same reference numerals. In an illustrative manner: Figure 1 The electronic display device is shown with its screen viewed from the front. Figure 2 A side view of the electronic display device is shown. Figure 3 A cross-section of an electronic display device is shown. Detailed Implementation

[0075] Figure 1 An electronic display device 1 is shown, which has a flat screen 2 for displaying information, a housing 4 for housing the screen 2, and a transparent screen cover 3 covering the screen 2. Viewed along the normal direction N of the screen 2, i.e., in... Figure 1 In the drawing plane, from back to front, the screen cover 3 extends beyond the screen 2 and beyond the housing 4 that houses the screen 2. The screen cover 3 is configured to emit light in a direction substantially parallel to the extension of the screen 2. This is symbolically represented by arrow 12. The screen cover 3 completely covers the screen 2. The screen cover 3 has an edge surface 5, which in... Figure 1 The center plane is oriented in the direction of the line of sight, thus appearing as the circumference of the screen cover 3. The edge surface 5 is divided into four parts: 5A, 5B, 5C, and 5D. Light is emitted through the edge surface 5.

[0076] Figure 2 A side view of the electronic display device is shown. The edge surface 5 of the screen cover 3 is independent and not surrounded. Therefore, the edge surface 5 or its entire portion 5D can be seen unobstructed from this viewpoint.

[0077] In addition, the electronic display device 1 has a mechanical coupling device 8 for coupling the electronic display device 1 to the shelf guide rail (not shown).

[0078] Figure 3 The electronic display device 1 is shown in Figure 1 The diagram shows a view cut along the horizontal direction.

[0079] The electronic display device 1 has two light sources 6 configured as light-emitting diodes (LEDs) and an electronic device 10. The electronic device 10 has an energy storage stage 14 (battery) on a circuit board 17 for storing energy and providing power, a communication stage 15 (transceiver) for radio-based communication with external devices (e.g., access points for radio-based ESL systems) and for receiving control data, and a control stage 16 (microcontroller) for controlling the light sources 6 according to the control data received via the communication stage 15. The circuit board also carries the LEDs 6 and the screen is connected to the circuit board (e.g., by means of a plug-in connection – not shown in detail).

[0080] Each light source 6 is coupled to a light distribution area 7. The light distribution area 7 is configured as a mechanical coupling device, specifically a pin, for mechanically coupling the screen cover 3 to the housing 4. The light distribution area 7 is inserted into the housing 4, thereby fixing the position of the screen cover 3.

[0081] The housing 4 protrudes below the screen cover 3, thereby forming a protrusion 11. This arrangement allows the protrusion 11 to be illuminated, making the emitted light particularly perceptible.

[0082] In addition, the light source 6 and the screen cover 3 form a screen lighting device for illuminating the screen 2.

[0083] If the light source is now manipulated to emit light via the control level, the light is guided into the screen cover 3 via the light distribution area 7. From there, the light is guided to the screen 2, so that the information displayed there can be well perceived by the human eye. Furthermore, the light is emitted in the direction of arrow 12, that is, substantially parallel to the screen 2. The edge surface 5 has a diffuser area, causing the light to scatter around the direction indicated by arrow 12, and thus also emitted in adjacent directions, indicated by arrow cluster 13. This applies to the entire edge surface 5, including its rounded corners.

[0084] Therefore, the electronic display device 1 can be well perceived from different viewing angles and distances. Thus, it can also attract attention when viewed from the side.

[0085] Finally, it should be reiterated that the accompanying drawings described in the foregoing detailed description are merely embodiments, and those skilled in the art can modify the embodiments in various ways without departing from the scope of the invention. For completeness, it should also be noted that the use of the indefinite article "a" or "an" does not preclude the possibility that multiple related features may exist.
