DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

With reference to FIGS. 1 to 8B of the drawings, there is shown an electronic display 10 embodying the invention, which may be used for displaying digital content, such as still images, video images and sound. Preferably and as illustrated, the electronic display is an electronic photo frame 10. More preferably, the photo frame 10 is adapted to be used with different types of standard electrical connections to facilitate its positioning in different positions, as hereinafter described.

Referring initially to FIGS. 1A and 1B, the photo frame 10 includes a screen 12 for displaying digital content, an electronic operating circuit (not shown) for operating the screen 12, and a support 14 supporting the screen 12 and the operating circuit. In the case of the photo frame 10, it is its body i.e. frame that acts as the support 14, hence also referred to as body 14. The photo frame 10 includes a speaker unit that is mounted in the body 14 and connected to the operating circuit, enabling the audio capabilities in synchronization with the display of the video images.

In the illustrated embodiment, the screen 12 is encircled by the body 14 in a way that the screen 12 is secured by the body 14.

The screen 12 may be a liquid-crystal display (LCD). Preferably, in-plane switching (IPS) technology is utilized for the screen for providing more consistent and accurate colour reproductions compared to conventional LCDs. The body 14 may be made of any suitable materials that are rigid and robust enough to support the whole screen 12 and the electronic components in the electronic operating circuit. For example, the body 14 may be made of wood, plastics or metallic materials.

The operating circuit preferably includes a wireless receiver, such as in particular a Wi-Fi module, for receiving digital content from a remote source (e.g. cloud), a memory (e.g. non-volatile memory) for storing the received digital content, and an image processor for processing the received digital content to be displayed on the screen 12.

During operation, a user may send or upload photos and videos from a smartphone to a cloud using a mobile application (app) installed on the smartphone, e.g. a dedicated app or any other supported apps such as a social media app. The digital contents may alternatively be uploaded via email. These photos and videos may then be retrieved from the cloud using the wireless receiver. Upon receiving the photos and videos and storing them in the memory of the operating circuit, the stored photos and videos may be displayed directly on the screen 12 after being processed by the image processor. Alternatively, the photos and videos may be processed and stored in the memory in the form of a playlist that may be displayed in the future without repeating the uploading and retrieving processes.

The operating circuit may also include a wireless transmitter (e.g. as part of the Wi-Fi module) for communicating data and signals to a remote device (e.g. a smartphone). For example, the wireless transmitter may transmit an identification signal of the photo frame 10 to a smartphone, allowing a wireless connection between the photo frame 10 and the smartphone, thereby permitting the operating circuit of the photo frame 10 to access the cloud associated with the smartphone. The wireless communication may also allow the smartphone to control the photo frame 10 and to manage the settings of the photo frame 10, e.g. to adjust the brightness of the screen 12. Such wireless technology may include, apart from Wi-Fi, Bluetooth or Near Field Communication (NFC) technologies.

As shown in FIG. 1B, the body 14 includes engaging means 16 for use in positioning of the body 14 in one of a standing position in which the body 14 stands on a surface (e.g. desktop) and a hung position in which the body 14 is hung on a surface (e.g. wall). The engaging means includes at least one hole 16. In the described embodiment, the engaging means includes six said holes 16, each shaped like a keyhole having a larger round end and a smaller opposite round end. A recess 18 is formed in the centre of the back of the body 14, with the holes 16 arranged on opposite sides of the recess 18. Providing the engaging means 16 at the centre of the body 14 helps balancing the whole photo frame 10 in the desired landscape or portrait orientation, when placed in the standing or hung position.

FIG. 2 shows a stand 20 of the photo frame 10, which is used for standing the body 14 on a surface, often a horizontal surface. The stand 20 has an elongated body 22 and includes engagement part 24 engageable with the engaging means 16 for standing the body 14 on a surface in the standing position. The engagement part 24 is provided at a near end of the stand 20 relative to the body 14 alongside with an electrical connector in the form of a 3.5 mm electrical plug 32. The engagement part 24 includes a cover 26 and at least one engaging part 28 on the cover 26 and engageable with the engaging means 16. The engagement part 24 is in the form of a square cover 26 supporting at its corners four hooking parts 28. Preferably, the hooking parts 28 are shaped and sized to fit the holes 16 on the body 14. The stand 20 also includes an electrical connecting means 30 for connecting the operating circuit to an external power source, e.g. DC power source, which will be discussed later.

FIG. 3 shows that the elongated body 22 is bendable and is adapted to stay bent at various curvature or angle it is bent to. This is useful for standing the photo frame 10 in various angular positions in either landscape or portrait orientation, and particularly useful when there is limited space on a uniform surface for both the body 14 and the stand 20 to stand on. For example, the body 14 may be stood on a table, while the stand 20 connected thereto may be adjusted, compacted and placed on a stepped surface, thus saving space. Since the stand 20 is bendable, the photo frame 10 may be used in landscape and portrait orientations, or any angled orientations.

FIGS. 4A and 4B illustrate the stand 20 being engaged or received in part in the recess 18 of the body 14. The electrical plug 32 protrudes laterally from an inner block of the cover 26 (FIG. 2), which is small enough to be accommodated in the recess 18. The cover 26, which is larger in footprint than the recess 18, covers the recess 18 when the stand 20 is fitted on the body 14. Further, the cover 26 is sufficiently large to also cover and conceal the holes 16, with the hooking parts 28 engaged with the holes 16, thereby resulting in a neat appearance.

Each of the holes 16 includes, at its smaller end, a periphery having a part that is inter-engageable with the hooking part 28 of the stand 20. When a user desires to use the photo frame 10 in a standing position, the use should first insert the hooking parts 28 on the cover 26 of the stand 20 into the larger ends of the respective holes 16, and then slide the cover 26 and thus the hooking parts 28 to reach and engage with the smaller ends, latching with the same.

FIG. 5 shows the electrical connection between the body 14 and the stand 20. The recess 18 of the body 14 is provided internally with a third electrical connector 34 connected to the operating circuit. Preferably, the third electrical connector 34 is an electrical socket sized to receive a 3.5 mm electrical plug, i.e. the electrical plug 32.

The first electrical connecting means 36 extends internally along the stand 20, with a first electrical connector 30, preferably a female connector, exposed at a far end of the stand 20 relative to the body 14 for electrical connection to a power source, and a second electrical connector i.e. electrical plug 32 at a near end of the stand 20 relative to the body 14 for electrical connection to the operating circuit via the third electrical socket 34. Power is provided from an external power source, via the electrical connectors 30, 32 to 34 to the operating circuit.

In a different scenario, if the user wants to use the photo frame 10 on a wall, which is a substantially vertical surface, he should replace the stand 20 by a second electrical connecting means 40 (FIGS. 6A and 6B).

The second electrical connecting means 40 is formed by an upper terminal 42 (FIGS. 7A and 7B), a lower terminal 46 (FIGS. 7C and 7D, and a flat cable 48 extending across the upper and lower terminals 42, 46. The upper terminal 42 comprises an electrical connecting unit 44 with an electrical plug 50 protruding at the top thereof, similar to the second electrical connector 32 in FIG. 2, for connection with the electrical docket 34 in the recess 18. The lower terminal 46 includes an electrical socket 52 at the bottom for connecting a power cable from an external power source.

FIGS. 6A and 6B illustrate the photo frame 10 when located in the hung position, with the use of the second electrical connecting means 40. One of the holes 16 in the body 14 may engage an engaging element, e.g. a screw, on the wall from which the body 14 is hung. The periphery of this hole 16 has a part inter-engageable and engaged with the screw (on the wall), whereby the photo frame 10 is located in the hung position.

With the use of the second electrical connecting means 40, its upper terminal 42 is accommodated in the recess 18 of the photo frame body 14. Specifically, the recess 18 is adapted to receive the whole electrical connecting unit 44, such that the upper terminal 42 does not take up any space externally of the body 14. In addition, the flat cable 48 is rather thin and it lies flat between the body 14 and the wall. This design allows the photo frame 10 to be used on the wall, lying closest possible thereto and against it.

In general, the third electrical connector 34 in the recess 18 on the back of the body 14 is useful for connection selectively with the second electrical connecting means 32 of the stand 20 when the body 14 is in the standing position, as described earlier, or with the electrical connecting unit 44 of the second electrical connecting means 40 when the body 14 is in the hung position.

As a further option, referring to FIGS. 8A and 8B, a simple power cable 52 fitted with a 3.5 mm electrical plug 54 may be used in place of the second electrically connecting means 40. In that case, the user may simply insert the electrical plug 54 into the electrical socket 34 in the recess 18. A thin cable should be chosen for use as the power cable 52. Alternatively or additionally, a notch or recess (not shown) may be formed in the periphery of the recess 18 for the power cable 52 to pass through without adding any thickness to the photo frame 10 on the back for lying closest possible to the wall.

The present invention, as discussed above, provides an electronic display with an additional and advantageous engaging feature over the pre-existing electronic displays. The engaging means, i.e. the holes 16 in the described embodiment, of the present electronic display is capable of selectively engaging a stand for use in a standing position or an engaging element for use in a hung position.

In addition, the bendable stand 20 allows the electronic display body 14 with the screen 12 to be placed in different orientations at different angles. For example, the body 14 may be arranged in a portrait orientation. The stand 20 is arranged not only to support the screen 12 and body 14, but also to connect power from an external power source to the operating circuit of the electronic display 10 due to the provision of the integrated power connection design.

The invention has been given by way of example only, and various other modifications of and/or alterations to the described embodiment may be made by persons skilled in the art without departing from the scope of the invention as specified in the appended claims. The described components of the electronic display may be arranged in a different way. Additionally, the electronic display may include additional components for carrying out additional functions.

For example, the screen of the electronic display may not be encircled in the support, but fixed and supported on top of the support. The screen may include a touch screen that allows the user to interact directly with the electronic display without using a smartphone, for example, to select a saved playlist from the electronic display, or to change a setting of the electronic display.

In addition or as an alternative to the wireless communication between the electronic display and the cloud, the electronic display may include an interface for receiving a memory stick or card on which digital contents are stored. The image processor may be operable to process the digital contents on the memory stick or card to be displayed on the screen.

For example, the construction of the stand may vary. The cover may be a grid supporting an engagement part which may not cover the recess or the holes of the support when the stand is attached to the support. The first, second and third electrical connectors may be of other forms of electrical connectors, i.e. any forms other than a 3.5 mm male or female connector.

Additionally, keyholes and hooking parts may be of other forms of engageable couplings. For example, the pair of engageable couplings may be magnetic coupling, threaded hole and fastener, bayonet coupling, etc.

Any reference to prior art contained herein is not to be taken as an admission that the information is common general knowledge, unless otherwise indicated.
