Abstract
The invention relates to an electromagnetic positioning track display device, and belongs to the electronic display technical field. The display device comprises a backlight reflecting plate, an electromagnetic positioning induction plate and a light resisting membrane; and the light resisting membrane is placed between the backlight reflecting plate and the electromagnetic positioning induction plate. The light resisting membrane is an insulating body, can be both a fully-independent membrane and an insulating layer uniformly coated on the electromagnetic positioning induction plate, and also can be formed by tightly clinging two mutually vertical polarized sheets for polarized light to penetrate. The color of the light resisting membrane is white or grey. The invention can effectively reduce the interference of the electromagnetic positioning induction plate to the color of a display through adding the light resisting membrane between the electromagnetic positioning induction plate and a display backlight reflecting plate.
Description
Technical field
The invention belongs to electronic information technical field, relate to a kind of electromagnetic positioning track display equipment, especially relate to a kind of electromagnetic positioning track display equipment that effective reduction electromagnetic location tablet disturbs Show Color.
Background technology
At present, electromagnetic location is because the bearing accuracy height can obtain advantages such as time writer angle of inclination and pressure information, and extremely market favor is widely used in equipment such as TabletPC handwritten computer, plotting sheet, handwriting pad, mobile phone, e-book.Electromagnetic positioning track display equipment generally is made up of demonstration module and electromagnetic location module.Show that module is used for carrying out demonstrations such as image, literal, generally comprise liquid crystal display and be LCD glass, colored filter, polaroid, backlight, drive controlling plate etc.The electromagnetic location module generally also claims inductive component, and inductive component is made up of time writer, tablet and control panel three parts.Tablet is installed in and shows in the module, i.e. the back side of reflecting plate backlight.Tablet switches the emission of electromagnetic field at a high speed and receives induced electricity magnetic pen information by the control and treatment of control panel.In order to be the time writer information that receives on the display in indication range, tablet is generally all bigger, can cover effective viewing area of whole display device.Electromagnetic positioning track display equipment requires reflecting plate backlight can allow electromagnetic wave to penetrate, therefore some restriction aspect thickness and material, use under the situation of versatility reflecting plate backlight in assurance as far as possible, reflecting plate backlight approaches and can not be fully every light, have certain light transmission, can cause the tablet color to enter in the backlight module, and the backlight of itself is white in the backlight module, in case white light is subjected to the influence of other colors, will the display effect generation of display be had a strong impact on.
Summary of the invention
Technical matters to be solved by this invention is to reduce the interference of the electromagnetic location assembly of electromagnetical type touch screen to display color.
The present invention solves the problems of the technologies described above the technical solution that is adopted and provides a kind of electromagnetical type touch screen display, comprise reflecting plate backlight, electromagnetic location tablet, between electromagnetic location tablet and reflecting plate backlight, increase by a light blocking film sheet, the size of light blocking film sheet covers reflecting plate backlight fully, and light tight.
According to the embodiment of the invention, the light blocking film sheet is an insulator.
According to the embodiment of the invention, the light blocking film sheet is white or grey.
According to the embodiment of the invention, the light blocking film sheet is the insulation course that evenly is coated with on the electromagnetic location tablet.
According to the embodiment of the invention, the light blocking film sheet is to be close to by two orthogonal polaroids of polarized light to constitute.

Embodiment
Further specify the present invention below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention includes reflecting plate 1 backlight, electromagnetic location tablet 3, light blocking film sheet 2 places between reflecting plate 1 backlight and the electromagnetic location tablet 3, and light blocking film sheet 2 sizes can cover reflecting plate 1 backlight fully, and light blocking film sheet 2 is light tight.Electromagnetic location tablet 3 itself is not luminous, if there is not the existence of light blocking film sheet 2, part white light backlight can be passed reflecting plate 1 backlight and be shone on the electromagnetic location tablet 3, electromagnetic location tablet 3 is with reflection ray, reflection ray passes reflecting plate 1 backlight again and enters in the module backlight, this moment, reflection ray merged electromagnetic location tablet color, and nature can destroy the display effect of display.After increasing light blocking film sheet 2 between electromagnetic location tablet 3 and the reflecting plate backlight 1, white light in backlight is passed reflecting plate 1 backlight and can only be shone on the light blocking film sheet 2, after 2 reflections of light blocking film sheet, reflection ray passes reflecting plate 1 backlight again and enters in the module backlight, because light blocking film sheet color is white or grey, so reflection ray still be white, can not destroy the backlight color, this moment, the electromagnetic location tablet regardless of what color material of employing was made, and its color can not influence backlight.
As Fig. 2 first embodiment light blocking film sheet by shown in the synoptic diagram that evenly insulation course of coating constitutes on the electromagnetic location tablet, the present invention includes reflecting plate 1 backlight, electromagnetic location tablet 3, the light blocking film sheet is to be made of the insulation course 6 that evenly is coated with on the electromagnetic location tablet 3, and insulation course 6 colors are white or grey.White light in backlight is passed reflecting plate 1 backlight and is shone on the insulation course 6, after insulation course 6 reflections, reflection ray passes reflecting plate 1 backlight again and enters in the module backlight, because the insulation course color is white or grey, therefore reflection ray still is a white, can not destroy the backlight color, electromagnetic location tablet 3 is no matter adopt any color material to make at this moment, and its color can not influence backlight.
As Fig. 3 second embodiment light blocking film sheet for to be close to shown in the synoptic diagram that constitutes by two orthogonal polaroids of polarized light, comprise reflecting plate 1 backlight, electromagnetic location tablet 3, the light blocking film sheet is formed for being close to by the two orthogonal x direction of polarized light polaroids 4 and y direction polaroid 5.White light in backlight is passed reflecting plate backlight and is shone earlier on the x direction polaroid 4, x direction polaroid 4 meeting reflecting part light, reflection ray passes reflecting plate 1 backlight again and enters in the module backlight, because polaroid can not change light color, this moment, reflection ray still was a white, can not destroy the backlight color. simultaneously x direction polaroid 4 also can the transmissive portions light splitter to y direction polaroid 5, this moment, light was linear light, can't see through y direction polaroid shines on the electromagnetic location tablet 3, owing to there is not light source, the electromagnetic location tablet is no matter adopt any color material to make, and its color can not have influence on backlight.
The present invention increases by a light blocking film sheet between the reflecting plate backlight of the tablet of electromagnetical type touch screen and display, can effectively reduce the interference of electromagnetic location tablet to display color, guarantees to use the display effect of the display of electromagnetic location technology.
