Description
Technical field
This utility model relates to electric resistance touch screen, refers in particular to electric resistance touch screen.
Background technology
Touch screen is as a kind of sensor, and in all trades and professions such as life, manufacturing industry, application is more and more extensive.Exist at present
The touch screen used on market is roughly divided into two big classes, resistive touch screen and capacitive touch screen.
Resistive touch screen is substantially all to scribble in the one side that the thin film structure plus glass, thin film and glass are adjacent
ITO(nano indium tin metal-oxide) coating, ITO has good electric conductivity and the transparency.When touch operation, thin film lower floor
ITO can touch the ITO of glass superstrate, spread out of the corresponding signal of telecommunication via induction apparatus, deliver to processor through change-over circuit,
The X that is converted on screen by computing, Y value, and complete the action clicked, and be presented on screen.The work of electric resistance touch screen
Principle mainly realizes the operation to screen content and control by pressure sensitive principle, and this screen body of touch screen part is
One piece of multi-layer compound film coordinated with display surface very resistive touch screen, wherein ground floor is glass or organic glass
Glass bottom, the second layer is interlayer, and third layer is polynary resin surface layer, and surface is also coated with the conductive layer of layer of transparent, covers
There is one layer of outer surface scratch resistant plastic layer hardened, smooth.Conducting shell and glassy layer sensing at polynary fat skin surface
Device is separated electric current by top layer by many small interlayers, when touching top layer pressure, touches bottom, controller simultaneously from
Four angles read the electric current matched and calculate the distance of finger position.This touch screen utilizes the conductive layer of two-layer high transparency to form
Touch screen, the spacing of two-layer is only 2.5 microns.When a finger is touching the screen, the two conductive layers of usual mutually insulated just exists
There has been a contact position, touch point, because wherein conductive layer connects the 5V even voltage field of Y direction so that detecting layer
Voltage is become non-zero from zero, and controller detects after this connects, and carries out A/D conversion, and by the magnitude of voltage that obtains compared with 5V,
The Y-axis coordinate of touch point, in like manner draw the coordinate of X-axis, here it is common most basic of all resistive technologies touch screens
Principle.
Capacitance-type touch screen technology is that the electric current sensing utilizing human body is operated.Capacitive touch screen is one piece four layers
Compound glass screen, the inner surface of glass screen and interlayer respectively scribble one layer of ITO, and outermost layer is a thin layer silicon soil glassivation, folder
Layer ITO coating, as work surface, four angles is drawn four electrodes, and internal layer ITO is that screen layer is to ensure good working environment.
When finger touches on the metal layer, owing to human body electric field, user and touch screen surface are formed with a coupling electric capacity, for height
Frequently for electric current, electric capacity is direct conductor, and then finger siphons away a electric current the least from contact point.This electric current is respectively from touching
Touch in the electrode on the corner of screen and flow out, and the distance of the electric current and finger to corner flowing through these four electrodes is directly proportional, control
Device processed, by the accurate calculating to these four current ratios, draws the position of touch point.Capacitance plate multi-point touch to be realized, leans on
Just it is to increase the electrode of mutual capacitance, briefly, it is simply that by screen block, one group of mutual capacitance module is set in each region
All work alone, so capacitance plate just, can realize after processing with the touch-control situation of independent detection to each region simply
Multi-point touch.
The popularization used along with electric resistance touch screen, touch screen has had been applied to the dribs and drabs of daily life.But
The boundary of a piece of land having a large amount of steam or cold uses, such as between sauna house bathroom and the Far East Area, rises when using electric resistance touch screen
Mist causes user cannot see operation interface clearly, affects human-computer interaction, and even maloperation causes serious consequence.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of resistive touch screen, can remove the mist of touch screen
Change, improve processing safety.
For solving above-mentioned technical problem, the technical scheme that this utility model provides is that one adds evanescence of heat mist electric resistance touch screen,
Including conductive film, it is characterised in that be printed with the conductive silver paste of a circle in described conductive film dorsal edge position, described
Conductive silver paste has two and connects end, is fitted with FPC flexible PCB on described connection end.
Described conductive silver paste is laciniation.
By increasing by a circle heating conductive silver paste at the conductive film back side, then heat conductive silver paste by DC source, add
Fog on touch screen is removed by the conductive silver paste of heat, makes touch-screen display interface clear, improves operability, improves when using
Security performance.
Accompanying drawing explanation
Fig. 1, this utility model structural representation.
Detailed description of the invention
For technique scheme, now lift a preferred embodiment and combine diagram and be specifically described.Referring to Fig. 1, this reality
With novel electric resistance touch screen, mainly include panel, ITO conductive film, double faced adhesive tape and FPC layer, electro-conductive glass, wherein.
Panel, typically uses PET, PMMA material as panel.Panel is pasted with one layer of ITO by OCA optical cement
Conductive film 1 (ITO refers to indium tin oxide).ITO conductive film is semi-conducting material, and it has electric conductivity, high printing opacity
Property and good mechanical performance.At the ITO conductive film close marginal position with the one side of plate contact, i.e. ITO conductive thin
The back side of film, is printed with a circle conductive silver paste 2.This circle conductive silver paste disconnects in junction, forms disjunct two and connects end 3.
Conductive silver paste shape can be printed for zigzag, it is also possible to is the concavo-convex connected type structure of great-wall shaped.It is fitted with at end 3 connecting
Except mist FPC flexible PCB (not shown).To FPC flexible PCB ibid unidirectional current, conductive silver paste then generates heat, by printing
Shape is different, increases heating power, reaches the effect except fog.
Electro-conductive glass is as backboard.Panel and backboard are combined by double faced adhesive tape, the conductive thin on panel and backboard
Film layer is adjacent, and when without External Force Acting, this two ITO conductive membrane layer is not in contact with each other.At panel and the conductive film of electro-conductive glass
Being additionally provided with the FPC flexible PCB that touch screen connects between Ceng, this FPC flexible PCB connects with external component.
Electric resistance touch screen of the present utility model, by the back of the body of the one side at conductive film Yu panel attachment, i.e. conductive film
Face printing one circle conductive silver paste, then attaches FPC circuit board, heats it and reach the effect except fog.This simple in construction,
Can effectively remove because the fog on the touch panel that causes such as steam, cold so that it is keep in use the most visually, carry
High simple operation and safety.
