Abstract
An electromagnetic touch screen display, which belongs to the field of electronic display technology, comprises a backlight reflective plate, an electromagnetic positioning inductor plate, and a light-resistant membrane arranged between the electromagnetic positioning inductor plate and the backlight reflective plate. The light resistant membrane is a white or gray insulator, which can be a completely independent membrane or an insulating layer uniformly applied on the electromagnetic positioning inductor plate or can be composed of two polarizers clung to each other and having vertical polarized light beams. The light-resistant membrane between the electromagnetic positioning inductor plate and the backlight reflective plate of the display can effectively suppress the influence of the electromagnetic positioning inductor plate on the color of the display.
Description
Technical field
The utility model belongs to electronic information technical field, relates to a kind of electromagnetical type touch screen display, especially relates to a kind of electromagnetical type touch screen display 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.The electromagnetical type touch screen display 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.The electromagnetical type touch screen display 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.
The utility model content
Technical problem to be solved in the utility model is to reduce the interference of the electromagnetic location assembly of electromagnetical type touch screen to display color.
The utility model 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 utility model embodiment, the light blocking film sheet is an insulator.
According to the utility model embodiment, the light blocking film sheet is white or grey.
According to the utility model embodiment, the light blocking film sheet is the insulation course that evenly is coated with on the electromagnetic location tablet.
According to the utility model embodiment, the light blocking film sheet is to be close to by two orthogonal polaroids of polarized light to constitute.
The beneficial effects of the utility model are, between the reflecting plate backlight of the tablet of electromagnetical type touch screen and display, increase by a light blocking film sheet, can effectively reduce of the interference of electromagnetic location tablet, guarantee the display effect of the display of application electromagnetic location technology display color.

Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises reflecting plate 1 backlight, electromagnetic location tablet 3, and 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 utility model comprises 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 utility model 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.
