(action in detail)
Then, the detailed action to the display device 1 with touch detection function illustrates.Figure 12 is to represent embodiment party The timing waveform of one action example of the display device with touch detection function that formula 1 is related to.As shown in figure 12, liquid crystal Show portion 20 according to the scanning signal Vscan supplied from gate drivers 12, scan successively one by one adjacent the in scan line GCL (n-1) row, line n, (n+1) row scan line GCL a horizontal line and shown.Equally, driving electrodes driver 14 Based on the control signal supplied from control unit 11, drive signal Vcom is supplied to the display part 10 with touch detection function , (m-1) in driving electrodes COML, adjacent row, m row, (m+1) row.
So, in the display device 1 with touch detection function, the 1H during each display is horizontal, timesharing is entered Row touch detection acts (A during touch detection) and display action (B during display).In touch detection action, at each 1H during one display is horizontal, touch detection is carried out by selecting different driving electrodes COML and applying drive signal Vcom Scanning.Hereinafter, it is acted and be described in detail.
First, gate drivers 12 apply scanning signal Vscan, scanning signal Vscan to (n-1) horizontal scanning line GCL (n-1) become from low level (level) and turn to high level.Thus, 1H starts during a display level.
Then, the A during touch detection, driving electrodes driver 14 applies to (m-1) row driving electrodes COML to be driven Signal Vcom, drive signal Vcom (m-1) become from low level turns to high level.Drive signal Vcom (m-1) is via electrostatic electricity Appearance is transferred to touch detection electrode TDL, and touch detection signal Vdet produces change.Then, if drive signal Vcom (m-1) from High level, which becomes, turns to low level, then touch detection signal Vdet similarly produces change.Touch inspection during the touch detection in A The waveform for the touch detection signal Vdet that survey signal Vdet waveform is corresponded in above-mentioned touch detection general principle.A/D Converter section 43 carries out touch detection by the way that the touch detection signal Vdet in A during the touch detection is carried out into A/D conversions.By This, carries out the touch detection of a detection line in the display device 1 with touch detection function.
Then, the B during display, source electrode driver 13 apply picture element signal Vpix to signal wire SGL, carried out for a water The display of horizontal line.In addition, as shown in figure 12, picture element signal Vpix change is transferred to touch detection electrode via parasitic capacitance TDL, touch detection signal Vdet can change, but the B during display, by making A/D converter sections 43 be changed without A/D, Influence of the picture element signal Vpix change to touch detection can be suppressed.Picture element signal is being carried out using source electrode driver 13 After Vpix supply terminates, gate drivers 12 make (n-1) horizontal scanning line GCL scanning signal Vscan (n-1) electric from height Flat change turns to low level, terminates during a display level.
Then, 12 pairs of gate drivers apply scanning signal Vscan, scanning letter from line n scan line GCL different before Number Vscan (n) becomes from low level turns to high level.Thus, start during next display level.
The A during next touch detection, 14 pairs of driving electrodes driver and m row driving electrodes COML different before Apply drive signal Vcom.Then, A/D conversions are carried out by change of the A/D converter sections 43 to touch detection signal Vdet, and entered The touch detection of row one detection line.
Then, the B during display, source electrode driver 13 applies picture element signal Vpix to pixel signal line SGL, for a water Horizontal line is shown.Also, display drive signals Vcmod is put on driving electrodes COML as public affairs by driving electrodes driver 14 Common-battery position.Here, display drive signals Vcmod current potential is for example as the touch drive signal Vcomt in A during touch detection Low level current potential.Further, since the display device 1 with touch detection function of present embodiment carries out dot inversion drive It is dynamic, therefore the picture element signal Vpix that is applied of source electrode driver 13 and the picture element signal Vpix phases during a display level before Than its polarity inversion.After B terminates during the display, 1H terminates during the display level.
After this, by the way that above-mentioned action is repeated, the display device 1 with touch detection function is by entirely showing The scanning in face and carry out display action, while touch detection action is carried out by the scanning in whole touch detection face.
In the display device 1 with touch detection function, during a display is horizontal (1H), touch detection action is set to exist A is carried out during touch detection, carries out display action B during display.So, due to making touch detection action and display action Carried out during difference, thus can carry out display action during identical one shows level and touch detection act this two Person, and influence of the display action to touch detection can be suppressed.
(configuration of touch detection electrode)
Figure 13 is the schematic diagram for the configuration for representing the touch detection electrode TDL that embodiment 1 is related to.Figure 14 is to illustrate to implement The schematic diagram of the first end of fine rule piece involved by mode 1 and the relative position relationship of the second end.Figure 15 is to show battle array The figure of the Moire fringe evaluation for the display device 1 with touch detection function being related to embodiment 1.
As shown in figure 13, the touch detection electrode TDL that embodiment 1 is related to is included in the plane parallel with opposing substrate 3 On along pixel arrangement direction Dy extend a plurality of elecroconductive thin line ML.Elecroconductive thin line ML is each other in elecroconductive thin line ML end MLe belongs to detection zone TDA via the first conducting portion TDB1 connections.Led in detection zone TDA, a plurality of elecroconductive thin line ML It is logical, and mutually there is certain interval and extend.Multiple detection zone TDA reciprocally have certain interval and extended.It is more Individual detection zone TDA is turned on via the second conducting portion TDB2 connections each other by the first conducting portion TDB1.Second conducting portion TDB2 is connected to the touch detection portion 40 shown in Fig. 1 via detection wiring TDG.Also, the conductings of the first conducting portion TDB1 and second Portion TDB2 with elecroconductive thin line ML identical materials by forming.By above-mentioned composition, reduce elecroconductive thin line ML bar number, And touch detection is carried out to certain scope by a plurality of elecroconductive thin line ML, therefore electricity when carrying out touch detection can be reduced Resistance.
Elecroconductive thin line ML includes fine rule piece Ua and fine rule piece Ub.Fine rule piece Ua is that have relative to pixel arrangement direction Dy The pattern of the conductive material extended to angle, including first end Ua1 and the second end Ua2.Equally, fine rule piece Ub be along with The pattern of the conductive material of the different direction extension in the directions of fine rule piece Ua extensions, including first end Ub1 and the second end Ub2.Fine rule piece Ua and fine rule piece Ub by fine rule piece Ua the second end Ua2 and fine rule piece Ub first end Ub1 connect and Conducting.
Also, it is thin that fine rule piece Ua the second end Ua2 and fine rule piece Ub first end Ub1 connecting portion turns into electric conductivity Line ML bending section TDC, fine rule piece Ua and fine rule piece Ub are turned back in each bending section TDC with defined angle.For example, implementing In the elecroconductive thin line ML that mode 1 is related to, fine rule piece Ua length and fine rule piece Ub equal length.Also, fine rule piece Ua prolongs Arranged relative to the size of pixel arrangement direction Dy angulations with the fine rule piece Ub directions extended relative to pixel in the direction stretched Column direction Dy angulations it is equal in magnitude.The elecroconductive thin line ML that embodiment 1 is related to is in each bending section TDC to pixel The direction of orthogonal direction Dx bendings changes.Fine rule piece Ua and fine rule piece Ub width are preferably more than 2 μm and less than 10 μm In the range of.Because fine rule piece Ua and fine rule piece Ub width if exist than 10 μm if big by people estimate identification can Energy property, resistance increases if width is less than 2 μm.
Touch detection electrode TDL elecroconductive thin line ML is the metal material of electric conductivity, by aluminium (Al), copper (Cu), silver (Ag), molybdenum (Mo), chromium (Cr), tungsten (W), the metal material of these alloy are formed.Or touch detection electrode TDL conduction Property fine rule ML by aluminium (Al), copper (Cu), silver-colored (Ag), molybdenum (Mo), chromium (Cr), tungsten (W), these oxide (metal oxide) shape Into conductive.Elecroconductive thin line ML can also be by the above-mentioned metal material for being laminated with more than one and above-mentioned metal The layered product patterning of oxide.Elecroconductive thin line ML can also be by being laminated with more than one above-mentioned metal material or metal The layered product pattern of the transparent conductive oxide such as oxide and the ITO (Indium Tin Oxide) of material as transparency electrode Change.Elecroconductive thin line ML is used for the transparent conductive oxides such as the ITO (Indium Tin Oxide) of the material of transparency electrode Resistance is low.The light transmittance of the identical thickness of elecroconductive thin line ML material is lower than the light transmittance of ITO (Indium Tin Oxide). For example, it is less than 10% that elecroconductive thin line ML material, which can also be light transmittance,.
As shown in figure 13, multiple detection zone TDA mutually have certain interval and configured.It is being configured with touch detection electricity Pole TDL elecroconductive thin line ML region and the region of elecroconductive thin line ML without touch detection electrode TDL, due to light-proofness Difference be present, thus there is a possibility that touch detection electrode TDL is easy to be estimated identification.Therefore, on opposing substrate 3, not It is configured at the detection wiring TDG dummy electrodes TDD being connected between adjacent detection zone TDA.Dummy electrodes TDD by with touch Detecting electrode TDL elecroconductive thin line ML identical materials are formed.Dummy electrodes TDD as long as there is with touch detection electrode TDL The light-proofness of equal extent, then can also be different materials.
Also, the dummy electrodes TDD shown in Figure 13 includes fine rule piece Uc and fine rule piece Ud.Fine rule piece Uc has and fine rule piece The size of Ua equal extents, abreast configured with the direction of fine rule piece Ua extensions.Fine rule piece Ud has and the equal journeys of fine rule piece Ub The size of degree, abreast configured with the direction of fine rule piece Ub extensions.Thus, it is configured with touch detection electrode TDL region and not It is that the difference of the light-proofness in such region diminishes, it is thus possible to reduce touch detection electrode TDL by the possibility of range estimation identification.
Dummy electrodes TDD has between fine rule piece Uc and fine rule piece Ud and is used as material not identical with elecroconductive thin line ML The cutting part TDDS of the otch of material.Therefore, cutting part TDDS hinders conducting for fine rule piece Uc and fine rule piece Ud, with touch detection Electrode produces capacitance difference.Therefore, in touch detection, even in finger close to touch detection electrode TDL and dummy electrodes TDD two In the case of person, it can also reduce dummy electrodes TDD to the absolute value shown in Fig. 6 | Δ V | the influence brought.So, pass through Cutting part TDDS splits dummy electrodes must be smaller than touch detection electrode TDL elecroconductive thin line ML area, can reduce pair The influence of touch detection precision.Say in the direction of relevant fine rule piece Ua extensions in embodiments described below and variation It is bright, it can be also applicable for the direction of fine rule piece Uc extensions.Also, the explanation in the direction about fine rule piece Ub extensions is for fine rule The direction of piece Ud extensions can be also applicable.

Evaluation example 6~10 and evaluation example 12~16 meet first condition.First condition is condition as follows：Fine rule Piece Ua the second end Ua2 is positioned at the direction from first end Ua1 towards target location, and target location is in pixel orthogonal direction Dx On apart from the first unit lengths of first end Ua1 Lx1 integral multiple more than 2 multiple, and on the Dy of pixel arrangement direction Apart from more than 2 multiple of the second unit lengths of first end Ua1 Ly1 integral multiple, the first unit length Lx1 integral multiple The value of multiple is different from the value of the multiple of the second unit length Ly1 integral multiple.In other words, first condition is bar as follows Part：Fine rule piece Ua the second end Ua2 positioned at direction from first end Ua1 towards target location, target location in pixel just Hand on the Dx of direction only apart from N times of the first unit lengths of first end Ua1 Lx1, and the only distance on the Dy of pixel arrangement direction M times of the second unit lengths of first end Ua1 Ly1, N and M are respectively more than 2 integer, and N and M are different.It therefore meets The elecroconductive thin line ML that the embodiment 1 of first condition is related to, as shown in figure 15, be evaluation example 6~10 and evaluation example 12~ 16, Moire fringe be evaluated as any one in A, B and C, the range estimation identification of Moire fringe is suppressed.
In addition, evaluation example 6, evaluation example 8~10, evaluation example 12~14 and evaluation example 16 meet second condition.Article 2 Part be the multiple of the first unit length Lx1 integral multiple value and the second unit length Ly1 integral multiple multiple value for 3 with Upper such condition.In other words, second condition be N and M be respectively more than 3 integer as condition.It therefore meets Article 2 The evaluation example 6 of part, the Moire fringe for evaluating example 8~10, evaluating example 12~14 and evaluating example 16 are evaluated as A or B, Moire fringe Range estimation identification be suppressed more.
Evaluate example 8~10 and evaluation example 12~14 meets the 3rd condition.3rd condition is the first unit length Lx1 integer The difference of the value of the multiple of the value of multiple again and the second unit length Ly1 integral multiple is condition as 1.In other words, the 3rd article Part is that N and M difference is condition as 1.Therefore, in the case of evaluation example 8~10 and evaluation example 12~14, Moire fringe A is evaluated as, the range estimation identification of Moire fringe is suppressed more.
As described above, pixel Pix the edges direction parallel to scan line GCL and the direction matrix parallel to signal wire SGL Configure shape.When scan line GCL and signal wire SGL are hacked Matrix cover, black matrix suppresses the transmission of light.Scan line GCL and letter When number line SGL is not hacked Matrix cover, scan line GCL and signal wire SGL suppress the transmission of light.Along flat in embodiment 1 Row in scan line GCL direction, parallel with pixel orthogonal direction Dx multiple linearity patterns and there is periodic pattern It is easy to be apparent on the Ad of viewing area.Also, due to along parallel to signal wire SGL it is direction, with pixel arrangement direction Dy Parallel a plurality of straight line, there is periodic pattern to be easy to be apparent on the Ad of viewing area.Therefore, along perpendicular to viewing area During the direction overlapping touch detecting electrode TDL on Ad surface, due to the pattern and the touch detection electricity that are apparent on the Ad of viewing area Pole TDL interferes and forms bright and dark pattern, therefore there is a possibility that Moire fringe is identified by range estimation.
In the display device 1 with touch detection function that embodiment 1 is related to, elecroconductive thin line ML, which is included, to be met The fine rule piece Ua for the first condition stated, the degree of identification can not be estimated so as to which the cycle of bright and dark pattern is easy to foreshorten to people.For example, The fine rule piece Ua that embodiment 1 is related to angularly extends relative to pixel orthogonal direction Dx and pixel arrangement direction Dy tools.Such as Fruit meets above-mentioned first condition, then the angle be certain size more than, thus the cycle of bright and dark pattern be easy to shorten.It is tied Fruit, in the display device 1 with touch detection function that embodiment 1 is related to, included and met by elecroconductive thin line ML The fine rule piece Ua for the first condition stated, Moire fringe can be reduced by the possibility of range estimation identification.
Also, if fine rule piece Ua meets second condition again on the basis of first condition is met, then can further it drop Low Moire fringe is by the possibility of range estimation identification.Because the cycle of above-mentioned bright and dark pattern further shortens.
Also, if fine rule piece Ua meets the 3rd condition again on the basis of first condition and second condition is met, then can Enough Moire fringes that further reduces are by the possibility of range estimation identification.Because the cycle of above-mentioned bright and dark pattern further contracts It is short.
Also, in the display device 1 with touch detection function that embodiment 1 is related to, in fine rule piece Ua and fine rule When piece Ub meets first condition, Moire fringe can be reduced by the possibility of range estimation identification.Also, it is related in embodiment 1 The display device 1 with touch detection function in, when fine rule piece Ua and fine rule piece Ub meet second condition, one can be entered Step reduces Moire fringe by the possibility of range estimation identification.Moreover, the display with touch detection function being related in embodiment 1 In device 1, when fine rule piece Ua and fine rule piece Ub meet 3 condition, it can further reduce Moire fringe and be identified by range estimation Possibility.
