concerning

"Television receiver with reflective, semi-transparent

Umbrella".

The innovation relates to a television receiver with a Jaalbtransparenteia screen to cover the receiver .

Han knows television receivers with semi-transparent ones Shades made of glass or other transparent material are provided, which the receiving tube against both mechanical Protect damage as well as against dust that adheres to them through electrostatic attraction »

Sin such a transparent screen covers the television receiver after it has been switched off and acts as a Mirror, but with the receiver switched on it gives a normal view of the picture tube without having to change or remove the screen *

The innovation creates a composition of a television receiver with a semi-transparent screen that is fastened in front of the picture tube »with a multi-pane mirror, in which the semi-transparent screen represents one pane of the multi-pane mirror and turned off the television receiver through this mirror with the receiver switched on, the television picture is visible on the semi-transparent screen.

The hiring should now be done in the following with reference to the drawings are explained in more detail. This show in?

Fig «1 shows a television receiver and mirror in part Cut;

Fig. 2 is a section along the line H-II of Fig. Tj 3 shows an enlarged partial section. Fig. 2j 4 shows a modification of the embodiment according to FIG.

In FIGS. 1 and 2, 1 denotes the housing of a television receiver, which surrounds a tube 2 and is closed with a screen 3 which is attached to the housing 1. The screen 3 consists of a plate h made of glass or another suitable transparent one Material such as methacrylate-polystyrene or another

■ - 3 -

transparent plastic »The screen 3 is the same We level the pane 7 of a multi-pane decorative mirror attached, which covers a television receiver.

As can be seen from Fig. 3, the inwardly facing surface is the pia. coated with a reflective tte h, haLbliehtdurehlässigen metal layer 5 which permits passage of light in atisreichendem mass. After the k shown in Fig. Embodiment, the metal layer 5 ^m * i is a layer 6 of a dielectric transparent material covered *

The plate k and the layer 5 are mainly used to generate a semi-transparent mirror which closes the tube of the television receiver when it is switched off, but allows viewing of the image when the receiver is switched on. In addition, with this plate and layer, the color can be changed or adjusted depending on the own spectral transparency curve, in order to make the image more effective «

This subordinate function of the mirrored plate

can be obtained with the help of a colored base glass material favor for plate 4.

The rail 6 has three functions, of which the main function is the protection of the metal layer. The two remaining functions derive from the interface effect in the layer 6 between the light rays reflected from the air-dielectric boundary layer surface and those from the dielectric-M © tail layer boundary surface reflected light rays from «

By correcting the thickness of the layer 6 made of dielectric material, this is backwards in the direction of the Picture tube of the television receiver reflected on

a preferably dark blue colored sore light limited * This achieves the second effect, the in a reduction of Liehthö'fen as a result of the reflection exists between the protective screen and the screen of the television set.

The light reflected by the layer 6 corresponds to FIG its color the complementary color of the reflected Light, which also works through the metal layer »so that there is a warm and effective light for the transmitted light Color results.

Claims (1)

Described above, the receiver and screen work like follows! If the television receiver is switched off, then the space behind the semi-permeable screen 3 is dark and the The observer only sees the reflected image of the surroundings, whereby the screen behaves like a mirror, so that the picture tube of the receiver and the other parts behind the mirror 7 disappear completely. · If the television receiver is switched on, then the light coming from the picture tube is brighter than the neighboring panes 7 » void the observer can observe the television picture through the screen 3. It goes without saying that the decision is not limited to what has been described in detail above and in the figures shown embodiment limited, *. "· PROTECTION CLAIM 1, compilation of a television receiver that works with is equipped with a semi-transparent screen fixed in front of the picture tube, with a multi-pane mirror, characterized in that the semi-transparent screen which forms a disc of the multi-disc dish, whereby The television receiver is covered by turning the mirror and the TV picture with the receiver switched on is visible on the semi-transparent screen.
