Wherein, owing to pressure sensitive does not require very high position precision as tactile control, as long as therefore in display panel, as long as arranging a pressure sensitive electrode 31 (and level pressure electrode 32) every one section of bigger distance (in full millimeter or several centimetres). Further, each pressure sensitive electrode 31 also can be relatively big like this, such as, directly can run through first substrate and extend to substrate edges, thus directly be connected with corresponding chip. That is, pressure sensitive electrode 31 inherently can play the effect of signal transmission line. Certainly, if arranging other special lead-in wires to transmit the signal of pressure sensitive electrode 31, also it is feasible.
Preferably, level pressure electrode 32 ground connection.
Obviously, as long as the electric capacity that level pressure electrode 32 connection fixing voltage just can shield finger also and between pressure sensitive electrode 31 forms electric capacity, but from simple and avoid the angle of the impact on other structures to consider, the best ground connection (connecing 0 level) of level pressure electrode 32.
Preferably, display panel comprises multiple for carrying out the pixel shown, the interval that level pressure electrode 32 and pressure sensitive electrode 31 are positioned between pixel.
As shown in Figure 1 and Figure 2, obviously, display can be impacted by level pressure electrode 32 and pressure sensitive electrode 31, it is preferred to they be located at for carrying out between the pixel shown.
Preferably, as a kind of mode of the present utility model, display panel is display panels, and its first substrate is provided with public electrode 13 and pixel electrode 15 towards second substrate side, and pressure sensitive electrode 31 is located at the position not having public electrode 13 and pixel electrode 15.
That is, as shown in Figure 1, display panel can be the form of display panels, and its first substrate is array substrate 1, and second substrate can be color membrane substrates 2. Simultaneously, this display panel is ADS pattern (AdvancedsuperDimensionSwitch, senior super dimension field translative mode) or IPS pattern (InPlaneSwitching, along face switching mode), therefore its public electrode 13 and pixel electrode 15 are all located on array substrate 1; Meanwhile, pressure sensitive electrode 31 should be positioned at the position not having public electrode 13 and pixel electrode 15, to ensure that it can play detection effect and not affect again display. Certainly, owing to each pixel having pixel electrode 15 and public electrode 13, therefore above pressure sensitive electrode 31 and the actual interval being preferably placed between pixel of level pressure motor 32.
Preferred further, pressure sensitive electrode 31 arranges with layer with pixel electrode 15 or public electrode 13 and mutually disconnects with pixel electrode 15 or described public electrode 31.
From the angle of Simplified flowsheet, pressure sensitive electrode 31 is preferably being formed with in a composition technique (being also exactly the setting of same layer) by same material layer with other structures, and pixel electrode 15 and public electrode 13 is comprised due to display panels, and they are between the pixels not necessarily, therefore as shown in Figure 1, pressure sensitive electrode 31 can be arranged (for itself and pixel electrode 15 with layer in figure) with layer with pixel electrode 15 or public electrode 13, certainly, now must ensure that pressure sensitive electrode 31 can not and be connected with the electrode of layer with it.
Preferably, public electrode 13 for plate electrode and is divided into multiple, and pixel electrode 15 is gap electrode and than public electrode 13 further from first substrate, public electrode 13 and pixel electrode 15 are separated by insulation layer 14; At least part of public electrode 13 is simultaneously as touch detection electrodes.
That is, as shown in Figure 1 and Figure 2, display panel can be ADS pattern, and wherein public electrode 13 is plate electrode, and pixel electrode 15 is gap electrode, and pixel electrode 15 is positioned at above public electrode 13. And, public electrode 13 is divided into multiple independent part, each corresponding multiple pixel of public electrode 13 (block such as 5mm �� 5mm), thus every public electrode 13 of block can also the mode of timesharing multiplexing (sharing) as self filling type touch control electrode. That is, display stage each public electrode 13 lead to into common electric voltage, then lead to into high-frequency signal in each public electrode 13 in the induction stage and detect its feedback signal, point when coming near public electrode 13 when there being user, the self-capacitance change of public electrode 13, feedback signal also changes, and can sense position of touch. The mode carrying out sharing due to above public electrode 13 and touch control electrode is known, therefore is not described in detail at this.
Preferred further, level pressure electrode 32 is made up of metallic substance.
When can be ADS pattern or IPS pattern when display panel, public electrode 13 and pixel electrode 15 are all positioned on array substrate 1, therefore color membrane substrates 2 does not have other conductive structures, so time can manufacture level pressure electrode 32 with the metallic substance (comprising alloy) that resistance is lower, to reduce its resistance. As previously mentioned, certainly, the interval that now level pressure electrode 32 is preferably placed between pixel.
Further preferred, public electrode 13 is located at the interval in whole pixel and between partial pixel, and the interval between rest of pixels does not have public electrode 13; The gap location that pressure sensitive electrode 31 and level pressure electrode 32 are located between the pixel not having public electrode 13; The additional pole 321 having the interval between the pixel of public electrode 13 to be also provided with suspension joint, additional pole 321 is positioned at second substrate towards first substrate side, and is made up of the metallic substance identical with level pressure electrode 32.
Such as Fig. 2, shown in Fig. 3, when public electrode 13 should all have distribution in each pixel for display, simultaneously owing to public electrode 13 is big sheet, therefore it also can also have distribution (namely each public electrode 13 covers multiple pixel) in the interval between partial pixel, and the interval being located at interval between pixel between adjacent common electrode 13, interval between these pixels does not just have public electrode 13, thus, the interval (being also exactly the interval between adjacent common electrode 13) that pressure sensitive electrode 31 and level pressure electrode 32 also should be located between those pixels not having public electrode 13, such level pressure electrode 32 only interval between partial pixel has distribution. and be made up of metallic substance due to level pressure electrode 32, though therefore it (is such as positioned at black matrix place) between pixel, but more or less still the display of adjacent pixels can be impacted, as front, interval (namely those do not have the interval of the public electrode 13) place that level pressure electrode 32 is only positioned between one part of pixel, this have between just causing level pressure electrode 32 pixel and between do not have the pixel display effect of level pressure electrode 32 different, namely cause display panel display uneven. above uneven for eliminating, therefore as shown in Figure 3, can arrange the additional pole identical with level pressure electrode 32 material 321 (obviously can layer same with level pressure electrode 32) at the pixel separation place (namely not having the pixel separation place of level pressure electrode 32) with public electrode 13, additional pole 321 and level pressure electrode 32 form the structure of similar " wire netting ". like this, touch control electrode (public electrode 13) will be covered by additional pole 321, is the touching signals preventing additional pole 321 from intercepting finger, therefore it should suspension joint and disconnecting with level pressure electrode 32.

Although it is to be understood, of course, that the display panels shared with ADS pattern and public electrode 13 and touch control electrode in the present embodiment is as an example, but the utility model is not limited to this. Such as, public electrode 13 can exchange with position and the form of pixel electrode 15; For another example, display panel also can be other patterns such as TN pattern (TwistedNematic, twisted nematic mode), IPS pattern; For another example, display panel also can be other forms such as Organic Light Emitting Diode (OLED) display panel; For another example, the structure that touch control electrode also can not be public but independent with public electrode 13; For another example, touch control electrode also can be mutual tolerance formula (being namely divided into scan electrode and induction electrode) etc.; No longer describe in detail one by one at this.
Embodiment 2:
As shown in Figure 4, the present embodiment provides a kind of method of display panel pressure sensitive, wherein display panel is above-mentioned display panel, and the method for display panel pressure sensitive comprises: the induction signal produced by analyzing pressure sensitive electrode judges display panel pressure.
That is, for above display panel, when there being tactile control to occur, owing to pressure second substrate can deform, thus pressure sensitive electrode and the interelectrode distance change of level pressure, the electric capacity between the two also changes, and the induction signal that pressure sensitive electrode provides also changes, by analyzing this induction signal, the pressure suffered by display panel can be known.
Preferably, for the display panel at the interval that above pressure sensitive electrode and level pressure electrode are positioned between pixel, above the lead-in wire of pressure sensitive electrode between pixel; The induction signal produced by analyzing pressure sensitive electrode above judges that the process of display panel pressure specifically comprises: lead to into high-frequency signal to pressure sensitive electrode, lead to into identical high-frequency signal to the lead-in wire below it simultaneously, and feed back, by analysis pressure sensitive electrode, the induction signal and judge display panel pressure.
Known, if leading in pressure sensitive electrode into high-frequency signal and using its feedback as induction signal, then can obtain good accuracy of detection; Simultaneously, when the interval that pressure sensitive electrode and level pressure electrode are positioned between each pixel, pressure sensitive electrode may be positioned at other lead-in wire (grid line, data line etc.) tops, therefore signal (especially high-frequency signal) wherein may be gone between in the impact of signal, for this reason, can leading to into the high-frequency signal same with pressure sensitive electrode in each lead-in wire when carrying out pressure detection, or say, available lead-in wire is as auxiliary electrode. Concrete, for the mode that above public electrode and touch control electrode share, it can be divided into tactile control stage and induction stage, and above pressure detection also can carry out reducing the test time used in the induction stage, namely, as shown in Figure 4, in the induction stage, all lead to into high-frequency signal to public electrode, pressure sensitive electrode, lead-in wire, and the signal fed back by public electrode judges position of touch, and the signal fed back by pressure sensitive electrode judges display panel pressure.
It should be appreciated that the illustrative embodiments that above enforcement mode is only used to principle of the present utility model is described and adopts, but the utility model is not limited thereto. For those skilled in the art, when not departing from spirit of the present utility model and essence, it is possible to make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
