Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and method for shielding aerosol particles around a display screen.

Display screen reading 1μ, more and more for skin diseases as well as eye and throat irritation! It is designed to receive wisdom. That is, the display screen is +15
An electric field is generated with a potential at 000V*. Reading the display can also become charged, for example by placing your foot on the floor. The potential for lI excitation is 4t+3000V to -6000V. The electric field strength between the display conit and the reader is 40,000V.
/- reaches. The air particles at ms become electrically charged and this causes a flow of particles in the electric field between the screen and the reading 1.

These particles become deposited on the reader's face, where they stick and cause the ailments mentioned above.

The present invention aims to provide a method and apparatus for suppressing such particle invasion towards a reader.

According to the invention, this object is combined by a method and an apparatus, the distinctive features of which will become apparent from the following description of the apparatus of the invention, illustrated by way of example in the accompanying drawings.

FIG. 1 shows a device according to the invention.

FIG. 2 is a sectional view taken perpendicularly through the section of FIG. 1.

FIG. 3 is a cross-sectional view of FIG. 1, showing a modified ring according to the present invention.

The apparatus shown in Figures 1 and 2 includes a screen 1, which is shown as rectangular but may also be square or irregularly shaped, and which is intended to be placed in front of a display screen. and has enough area to reflect the display screen. The screen of the invention comprises a rectangular electrically conductive frame 2, the frame 2 comprising the 1116th and 21st
As shown in Figure Il, there is a nylon tank 3 stretched over it and a net 3 in the opposing part of the frame 2.
and an electrically conductive wire 4 stretched in contact with. Reference number 5 indicates the connection of the frame to earth potential, the number of wires is matched to the size of the frame 2, and in turn the worker adjusts the size of the display screen in front of the tube of the visual display unit. It is adjusted accordingly.

Instead of being applied according to FIG. 11I and FIG.
The wires 4 may be wrapped within the nylon mesh or interwoven with it in greater or lesser amounts, i.e. they are adjacent to the threads of the mesh and-
It is meant to be cut and run.

The described screen 1 is mounted in front of a dedicated display screen such as that used in visual display units.

The flow of particles generated by the electric field between the reader and the display screen thus passes through a nylon cord 3 which is provided with an electrically conductive wire 4 and which is connected to the earthed frame 2. The reader's face is therefore unaffected by the screen 1, which has a screen 1, so that diseases of the skin 1 and stings in the eyes or throat are prevented. Does not occur.

The electrical properties of the -3 and electrically conductive 9 ears 4 are thus sufficient to shield said electric field.

The screen 6 shown in FIG. 3, like the screen 1, comprises an electrically conductive frame 2 and a nylon mesh 3 stretched across it, but the wires 4 of the screen 1 The stomach is replaced by an electrically conductive hole 7 which is transparent and electrically connected to the frame 2.

The screen 6 is suitably mounted so that the conductive cabinet 7 is closest to, ie facing, the display screen. The screen of this embodiment effectively suppresses the flow of particles towards the reader and particularly towards the reader's face.

The screen of the embodiment is modified in accordance with the present invention. For example, the frame may consist of two opposing frame sections, which are mounted in a holder or on a demisplay unit to be read.

The means arranged for shielding the electric field, ie nylon mesh and wire or sheathing, also have other suitable embodiments. Any other electrically insulating plastic material may be used in place of nylon.

[Brief explanation of the drawing]

1 is a diagram of a device according to the invention; FIG. Figure 2 shows @*** passing perpendicularly through the stomach in Figure 1. FIG. 3 is a view from the IFi plane of FIG. 1, showing a device modified in accordance with the present invention. In the figure, 1 is the screen, 2 is the frame, 3 is the rope, and 4
is the wire, 5 is the connection to ground potential, 6 is the screen,
7 indicates -.
