The utility model embodiment just is being based on the ADS technology and the H-ADS technology has proposed the embedded touch screen structure of a kind of new condenser type.Below in conjunction with accompanying drawing, the embodiment of the embedded touch-screen of condenser type, its driving method and the display device that the utility model embodiment is provided is described in detail.
Each layer film thickness and shape do not reflect the true ratio of tft array substrate or color membrane substrates in the accompanying drawing, and purpose is signal explanation the utility model content just.
The vertical view of tft array substrate in Fig. 2 and the horizontal section schematic diagram that is respectively the embedded touch-screen of condenser type that the utility model embodiment provides shown in Figure 3 and the touch-screen.As shown in Figures 2 and 3, the embedded touch-screen of the condenser type that the utility model embodiment provides specifically comprises: color membrane substrates 1, tft array substrate 2, and the liquid crystal layer 3 between color membrane substrates 1 and tft array substrate 2, be formed with a plurality of pixel cells 4 that are the matrix arrangement in the embedded touch-screen of this condenser type; Between the pixel cell 4 of tft array substrate adjacent lines, have two signal lines 5, and whenever two adjacent row pixel cells 4 are one group of pixel cell row 6, share the data signal line 7 between this two row pixel cell 4; Also comprise:
The above-mentioned touch-screen that provides at the utility model embodiment adopts double-gate structure, by the signal line of the quantity that doubles, saves the position of a part of data signal line.And, because the precision of touch-screen is usually at grade, and the precision of LCDs is usually at micron order, can find out and show that required precision is far longer than the required precision of touch-control, therefore, the touch-control drive electrode of realizing touch controllable function can be arranged on the position of the data signal line that saves, namely be arranged on the gap location between the adjacent pixel unit row, both can guarantee the precision that touch-control is required, can too much not take again the open area of pixel cell, can guarantee that touch-screen has larger aperture opening ratio.
In addition, the utility model above-mentioned touch-screen of implementing to provide equally also is applicable to twisted-nematic (TN, Twisted Nematic) type.Particularly, on the TN type tft array substrate based on double-gate structure, can be with the part public electrode wire as the touch-control drive electrode, on color membrane substrates with strip ITO public electrode as the touch-control sensing electrode because the TN type belongs to prior art, do not do at this and give unnecessary details.
Further, for phase mutual interference between the display that reduces touch-screen and the touching signals, can adopt in the specific implementation touch-control and show the mode that timesharing drives, to avoid showing and touch-control influences each other in the course of the work each other as far as possible.
Particularly, the driving method of the embedded touch-screen of above-mentioned condenser type that the utility model embodiment provides, sequential chart as shown in Figure 4 specifically comprises:
At first, touch-screen is shown that the time of each frame (Vsync) is divided into displaying time section (Display) and touch-control time period (Touch), for example the time of demonstration one frame of touch-screen is 16.67ms in the driving sequential chart shown in Figure 4, choose wherein 4ms as the touch-control time period, other 12.67ms is as the displaying time section, can certainly be according to the processing power of IC chip suitable both durations of adjustment are not specifically limited at this.
At displaying time section (Display), touch-control drive electrode Tx and touch-control sensing electrode Rx are applied low level signal, simultaneously, to every in touch-screen signal line G1, G2 ... Gn applies scanning gate signal successively, and data signal line Data is applied the GTG signal, the upset of control liquid crystal molecule; Be as good as with normal liquid crystal panel principle of work during this period of time.
At touch-control time period (Touch), Tx applies touch scanning signals to the touch-control drive electrode, voltage signal and the output of touch-control sensing electrode Rx coupling touch scanning signals.By the touch of finger, change the inductance capacitance between two electrodes of position, touch point, thereby change the size of the terminal receiver voltage signal of touch-control sensing electrode Rx, realize touch controllable function.In the touch-control time period, every signal line in the touch-screen and the input of data signal line no signal.
The below is described in detail the concrete structure of the touch-control drive electrode that arranges in the tft array substrate in the above-mentioned touch-screen.
In the specific implementation, data signal line in touch-control drive electrode and the tft array substrate can be arranged with layer, like this, when the preparation tft array substrate, do not need to increase extra preparation section, only need to can form by a composition technique figure of data signal line and touch-control drive electrode, can save preparation cost, the improving product added value.
Particularly, because the touch-control drive electrode is arranged between the adjacent pixel cell row, and the gap between the pixel cell generally only has about 5 microns usually, therefore, the width of each bar touch-control drive electrode is also very thin, this will cause less over against area between touch-control drive electrode and the touch-control sensing electrode, and the coupling capacitance of generation is less also.In order to guarantee that Nodes between touch-control drive electrode and the touch-control sensing electrode is that the coupling capacitance at overlapping place reaches required numerical value, generally about 3pF, can consider to reach the required coupling capacitance of assurance by increasing the mode over against area at touch-control drive electrode and the overlapping place of touch-control sensing electrode.
In the specific implementation, can take dual mode, the first: can with each touch-control drive electrode and the adjacent lines pixel cell between the overlapping place of two signal lines outer male structure A is set, as shown in Figure 5, the concrete shape that is somebody's turn to do outer male structure A can be rectangle as shown in Figure 5, can also be other common shape, not do restriction at this.The outer male structure A of touch-control drive electrode is arranged on and the overlapping place of signal line, can not take the open area of pixel cell, therefore can not affect the aperture opening ratio of touch-screen; And because touch-control has adopted the timesharing driving, therefore the signal through the transmission of touch-control drive electrode can not exert an influence to the normal demonstration of display yet.Like this, the outer male structure A that has by the touch-control drive electrode just can increase between touch-control drive electrode and the touch-control sensing electrode over against area, thereby guarantee to produce between touch-control drive electrode and the touch-control sensing electrode required coupling capacitance.
The mode over against area that the second increases between touch-control drive electrode and the touch-control sensing electrode is: with layer at least one touch point electrode is set with public electrode (for example ITO public electrode) transparent in the tft array substrate, the overlapping place of the two bar signal lines of each touch point electrode between each touch-control drive electrode and adjacent lines pixel cell, and be electrical connected by via hole and overlapping touch-control drive electrode; Namely newly-increased touch point electrode and public electrode form by a composition technique, and newly-increased touch point electrode and public electrode use the same material preparation like this, are generally the transparent conductive oxide material such as ITO or IZO.Wherein, the touch point electrode is can be with the shape of the outer male structure A shown in Fig. 5 similar and size is suitable.
Can find out, the outer male structure that the touch-control drive electrode has in newly-increased touch point electrode and the first kind of way in the above-mentioned second way is arranged on identical zone in the vertical view of tft array substrate, namely be arranged on and the overlapping place of signal line, but both are arranged on the different retes.Therefore, the second way can not take the open area of pixel cell equally when implementing, and can not affect the aperture opening ratio of touch-screen.And, by and the touch point electrode that is electrical connected of touch-control drive electrode just can increase between touch-control drive electrode and the touch-control sensing electrode over against area, thereby guarantee to produce between touch-control drive electrode and the touch-control sensing electrode required coupling capacitance.
Usually, on the array base palte of ADS type liquid crystal panel, public electrode is positioned at lower floor's (more close underlay substrate) as plate electrode, and pixel electrode is positioned at upper strata (more close liquid crystal layer) as gap electrode, is provided with insulation course between pixel electrode and public electrode.And on the array base palte of HADS type liquid crystal panel, pixel electrode is positioned at lower floor's (more close underlay substrate) as plate electrode, and public electrode is positioned at upper strata (more close liquid crystal layer) as gap electrode, is provided with insulation course between pixel electrode and public electrode.
On the array base palte of HADS type liquid crystal panel, the touch-control drive electrode can be blocked by the public electrode of more close liquid crystal layer owing to arranging with layer with data signal line, is unfavorable for being arranged on the touch-control sensing electrode detector touch scanning signals on the color membrane substrates.Therefore, arrived by the touch-control sensing electrode detector in order to guarantee that the touch scanning signals that applies on the touch-control drive electrode is easier, particularly, pattern according to the concrete display panels of using of above-mentioned touch-screen, when HADS type touch-screen, it is the top that public electrode in the tft array substrate is positioned at pixel electrode, public electrode pattern as shown in Figure 6, the ITO public electrode is set to engraved structure in the position corresponding with the touch-control drive electrode, be that the ITO public electrode arranges the pattern without public electrode in the position corresponding with the touch-control drive electrode, shown in the B zone among Fig. 6.
Further, because the precision of touch-screen is usually at grade, and the precision of LCDs is usually at micron order, show that required precision is far longer than the required precision of touch-control, therefore, the touch-control drive electrode of realization touch controllable function may not can take the gap between whole adjacent pixel unit row, like this, gap location that can be between the adjacent set pixel cell except being provided with touch-control drive electrode row, as shown in Figure 7, the at least one public electrode wire Vcom that public electrode in setting and the tft array substrate is electrical connected is to increase the stability of the entrained common electrode signal of public electrode.
The below is described in detail the concrete structure of the touch-control sensing electrode that color membrane substrates in the above-mentioned touch-screen has.
In the specific implementation, the touch-control sensing electrode can also can be positioned at the color resin of color membrane substrates towards the one side of liquid crystal layer between the substrate and color resin of color membrane substrates, can also be positioned at the dorsad one side of liquid crystal layer of color membrane substrates.
In the specific implementation, can the guarded electrode on the color membrane substrates (shielding ITO) be divided into the touch-control sensing electrode of suitable width according to required touch-control precision, generally speaking, the width of every touch-control sensing electrode is good at 2 ~ 6mm.And the precision of touch-screen is usually at grade, and the precision of LCDs can be found out to show that required precision is far longer than the required precision of touch-control usually at micron order, and therefore, general every touch-control sensing electrode all can corresponding multirow pixel cell.
When the touch-control sensing electrode is positioned at color membrane substrates dorsad during the one side of liquid crystal layer, because the spacing between touch-control sensing electrode and the touch-control drive electrode is larger, therefore, as shown in Figure 8, directly each bar touch-control sensing electrode 9 is prepared into planar structure can guarantee that coupling capacitance is in suitable scope.
When the touch-control sensing electrode is positioned at color membrane substrates towards the one side of liquid crystal layer, because the spacing between touch-control sensing electrode and the touch-control drive electrode is less, in order to guarantee that coupling capacitance improves the feasibility of touch-control in suitable scope, as shown in Figure 9, each bar touch-control sensing electrode 9 can be designed to have the grid electrode structure, and the touch-control sensing electrode of grid electrode structure is relative with the black matrix area of color membrane substrates, so just can utilize black matrix to hide the fenestral fabric of touch-control sensing electrode, can the aperture opening ratio of display not exerted an influence.
Particularly, because the touch-control sensing electrode of the fenestral fabric that arranges at color membrane substrates can the occluded pixels unit, therefore, the material of touch-control sensing electrode can be specially transparent conductive oxide for example ITO or IZO, also metal can be, when adopting metal to make the touch-control sensing electrode, its resistance can be effectively reduced.
In addition, when touch-control drive electrode and touch-control sensing electrode are set, in order to reduce connected IC chip cost, can by adjacent a plurality of touch-control drive electrodes are passed through the mode of wire conducting at arbitrary end, be reduced to and respectively drive the quantity that the touch-control electrode provides the driving passage (channel) of electric signal; By adjacent a plurality of touch-control sensing electrodes are passed through the mode of wire conducting at arbitrary end, reduce the quantity of the induction channels (channel) that is connected with each touch-control sensing electrode.For example, resolution is the touch-screen of 1280*800, the touch-control drive electrode that can consider per 120 pixels are comprised is by the wire conducting, as a touch-control drive electrode, the touch-control sensing electrode of 100 length in pixels as a touch-control sensing electrode, therefore, is only needed the channel interface of 10 touch-control drive electrodes altogether, the channel interface of 8 touch-control sensing electrodes has reduced the requirement to the IC chip.
Based on same utility model design, the utility model embodiment also provides a kind of display device, comprise the embedded touch-screen of above-mentioned condenser type that the utility model embodiment provides, the enforcement of this display device can referring to the embodiment of the embedded touch-screen of above-mentioned condenser type, repeat part and repeat no more.
The embedded touch-screen of a kind of condenser type and display device that the utility model embodiment provides, the touch-control sensing electrode that extends along the line direction of pixel cell is set at color membrane substrates, adopt double-gate structure at tft array substrate, be to have two signal lines between the pixel cell of adjacent lines, every two adjacent row pixel cells are one group of pixel cell row, share the data signal line between this two row pixel cell, by the signal line of the quantity that doubles, save the position of a part of data signal line.And, because the precision of touch-screen is usually at grade, and the precision of LCDs is usually at micron order, can find out and show that required precision is far longer than the required precision of touch-control, therefore, the touch-control drive electrode of realizing touch controllable function can be arranged on the position of the data signal line that saves, namely be arranged on the gap location between the adjacent pixel unit row, both can guarantee the precision that touch-control is required, can too much not take again the open area of pixel cell, can guarantee that touch-screen has larger aperture opening ratio.
