Description

[0001] The invention relates to a display apparatus comprising a display and, connected to the display, a base part which forms a support surface for supporting the display apparatus on a substantially planar surface.

[0002] Flat displays are lighter than traditional displays provided with cathode ray tubes, so they are more easily mounted on a wall. Thus flat displays can be mounted with the aid of lighter wall fasteners than the traditional displays, and even on light partition walls. The wall installation saves table space, and- the viewing distance can be increased so that it is longer than previously.

[0003] Prior art flat displays generally have a fixed base part, supported on which the display can be arranged on a table top. Such displays can not be mounted on vertical surfaces. If the base part can be detached, it may be removed and the display could be mounted on a wall etc. This requires then for instance separate wall fasteners. There may also be already fasteners on the backside of the display, but then a wall installation of the display requires that the display apparatus is taken apart (the base part and the display).

[0004] Further, if the base part can be detached from the display, the cables between the base part and the display must be sufficiently long, so that the connection between the parts can be maintained disregarding the detachment of the base part. Alternatively both the display and the base part can be provided with connectors, whereby a longer cable is refitted between them for the wall installation. It is also possible to use solutions where the cables do not pass through the base part.

[0005] In such applications the height or inclination of the display can not be adjusted after the fastening.

[0006] These problems can be solved with a display apparatus according to the invention which is characterised in that

• the display and the base part can be moved in relation to each other, at least to a first operating position and to a second operating position, of which in the first operating position the direction of the support surface differs substantially 90 degrees from the direction of the support surface in the second operating position, and
• further the base part of the display apparatus comprises fastening means for fastening the display apparatus to a substantially planar surface.

[0007] The display apparatus according to the invention can be fastened to a planar surface which is horizontal, vertical, or otherwise directed, without dissembling the apparatus. Thus the wall installation is rapid and easy. The display is further sufficiently light-weight, so that it can be easily fastened even on a light wall and without any robust fastening means. According to a preferred embodiment of the invention the base part can be arranged below the display apparatus when the apparatus is fastened to a vertical surface.

[0008] According to a further preferred embodiment of the invention the base part of the apparatus comprises a support part and an arm part. On a horizontal surface the apparatus can be placed so that it is supported by the support part. The inclination of the display in relation to a vertical surface as well as its location in the height direction can be adjusted with the aid of the arm part, without detaching the apparatus from the surface.

[0009] Further the display can be arranged in a vertical or in a horizontal position, without detaching the apparatus from the surface, by twisting it around a certain rotational axis when the display apparatus is fastened to a planar surface.

[0010] Thus a display apparatus according to the invention can be fastened to a vertical surface so that the mechanical adjustments of the display remain substantially the same as in a table top installation.

[0011] Further, an audio or a multimedia equipment can be located in the base part, which the equipment comprises for instance speakers, a microphone and/or a camera, and other control arrangements. According to a preferred embodiment of the invention the base part is located below the display in the wall installation, whereby any audio equipment and adjustment arrangements are easy to use. Further, space for the apparatus cables can be arranged in the arm part.
