Embodiment
With reference to the accompanying drawings, the specific embodiment of the present invention is described in further detail.
Fig. 1 illustrates according to touch control display of the present invention, has first embodiment of the contact panel of metal nano optical grating construction.With reference to Fig. 1, touch control display comprises contact panel 10, display panel 20 and following polaroid 30, and wherein display panel 20 is positioned at the below of contact panel 10, and following polaroid 30 is arranged at the below of display panel 20.Because contact panel 10 separates with display panel 20, this touch control display is an On-cell type touch-control product.
In this specific embodiment, display panel 20 comprises two substrates 201 and 203, and between substrate 201 and substrate 203 liquid crystal layer 205 is set.In addition, following polaroid 30 is positioned at the below of display panel 20, is used for the light that penetrates is carried out polarization.Contact panel 10 comprises two substrates (can be described as upper substrate and infrabasal plate), and upper substrate has diaphragm 101 and be positioned at the nesa coating of diaphragm 101 belows, and infrabasal plate has diaphragm 103 and is positioned at the nesa coating of diaphragm 103 belows.Preferably, this contact panel adopts the capacitor type touch control manner, and as shown in Figure 1, contact panel 10 has two induction patterned layer 105 and 107, wherein responds to the lower surface that patterned layer 105 is positioned at diaphragm 101, and induction patterned layer 107 is positioned at the upper surface of diaphragm 103.
It needs to be noted,, a metal nano optical grating construction can be set, to be used as the polarization function of responding to patterned layer 107 and having last polaroid at the upper surface of diaphragm 103 according to the correlation properties of metal nano grating.As previously mentioned, in the prior art, induction patterned layer 107 is separate element with the last polaroid that is positioned at display panel 20 tops, thereby it is relative thicker to dispose the touch control display of responding to patterned layer and last polaroid.Yet the present invention uses a metal nano optical grating construction, makes the polarization function that the time spent also has polaroid concurrently of doing of its performance induction patterned layer, thereby has reduced manufacturing cost and reduced display thickness.
Fig. 2 illustrates according to touch control display of the present invention, has second embodiment of the contact panel of metal nano optical grating construction.Be similar to Fig. 1, also comprise contact panel 10, display panel 20 and following polaroid 30 in touch control display, wherein display panel 20 has substrate 201 and 203 and between the two liquid crystal layer 205.But different is with Fig. 1, and variation has taken place in the storing position of metal nano optical grating construction, and as shown in Figure 2, the metal nano optical grating construction is positioned at the lower surface of diaphragm 103, equally as induction patterned layer 107 and have the polarization function of polaroid concurrently.In addition, in Fig. 1 and Fig. 2, also be provided with a bonding coat 109 between upper substrate and the infrabasal plate.
Fig. 3 illustrates according to touch control display of the present invention, has the 3rd embodiment of the contact panel of metal nano optical grating construction.With reference to Fig. 3, the display panel in the touch control display and following polaroid can be corresponding to display panel in the touch control display illustrated in figures 1 and 2 and following polaroids, thereby continue the identical Reference numeral of employing and indicated.In Fig. 3, contact panel 40 only comprises touch control film 401, and will respond to upper surface and lower surface that patterned layer 403 and 405 is placed on touch-control diaphragm 401 respectively.Preferably, will respond to patterned layer 405 and adopt the metal nano optical grating construction to form, that is to say, and form a metal nano optical grating construction in the lower surface of touch-control diaphragm 401, and make it have the polarization function of polaroid concurrently.
More than, understand the touch panel structure provided of capacitor type touch control manner of the present invention specifically by Fig. 1, Fig. 2 and Fig. 3.For the capacitor type contact panel; for example; it is four layers of compound glass screen; the inside surface of glass screen and interlayer respectively scribble an ITO transparent conductive film layer; outermost layer is a glassivation, and the ITO coating of interlayer is drawn four electrodes as workplace on four angles; the ITO coating of inside surface plays shielding action, to guarantee good working environment.When finger touch was on metal level, because people's bulk electric field, operator and touch screen surface had formed a coupling capacitance, and for high-frequency current, electric capacity is direct conductor, so finger siphons away a very little electric current from contact point.This electric current flows out the electrode from four jiaos of touch-screen respectively, and the electric current of these four electrodes of flowing through is directly proportional with the distance of pointing four jiaos, and processor is by the accurate Calculation to these four current ratios, thereby draws touch point position.
Fig. 4 illustrates according to touch control display of the present invention, has the 4th embodiment of the contact panel of metal nano optical grating construction.This touch control display is the resistor-type touch control manner.In simple terms, the resistor-type touch control display utilizes pressure sensitive to control, its major part is a resistance film screen that cooperates very much with display surface, this is a kind of laminated film of multilayer, it with one deck glass or duroplasts flat board as basic unit, the surface scribbles a transparency conducting layer, is stamped one deck outside surface cure process, smooth anti-friction plastic layer above again.The transparent isolating points that its inside surface also has a coating, have many tiny (for example less than 1/1000 inches) is betwixt kept apart two conductive layers up and down, to be electrically insulated.When the finger touch screen, two conductive layers have just had electrical contact in the position, touch point, cause that resistance changes, and produce signal on X and Y both direction, deliver to touch screen processor then.Processor detects this contact and calculates that (mode according to analog mouse accurately draws the position, touch point again for X, position Y).
With reference to Fig. 4, touch control display comprises contact panel 50, display panel 20 and following polaroid 30.Wherein, contact panel 50 has diaphragm 501 and diaphragm 503, and responds to the lower surface that patterned layer 505 is positioned at diaphragm 501, and induction patterned layer 507 is positioned at the upper surface of diaphragm 503.Preferably, will respond to patterned layer 507 and adopt the metal nano optical grating construction to form, and make it also have the polarization function of polaroid concurrently.
In sum, to touch control display shown in Figure 4, in contact panel, be provided with a metal nano optical grating construction, when being used as the induction pattern, also have the polarization function of polaroid concurrently at Fig. 1.Preferably, this metal nano optical grating construction is to adopt the ITO conductive material to form.In addition, the raster width of this metal nano optical grating construction and interval are between 0.01 μ m to 1 μ m.
Adopt touch control display of the present invention, one metal nano optical grating construction is set in contact panel, suitable width and interval based on the metal nano optical grating construction, make it be used as induction pattern and last polaroid, thereby can remove the last polaroid that originally was positioned between contact panel and liquid crystal panel, so that reduce the thickness of touch control display and save manufacturing cost.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also do various changes and replacement to the specific embodiment of the present invention.These changes and replace all drop in claims of the present invention institute restricted portion.
