The control terminal of secondary signal pin TP, n the 4th switch units 141 be respectively connecting to corresponding to the second controlling switch CKHR,
CKHG、CKHB.Alternatively, n the 4th switch units 141 are identical with the type of the 3rd switch unit 133, here, being cut with the 4th
Unit 141 is changed as exemplified by N-type transistor.
Alternatively, the second controlling switch includes n different data controlling switch CKHR, CKHG and CKHB etc., n the individual 4th
The control terminal of switch unit 141 connects n different data controlling switch respectively, and phase is connected in multiple display control units 140
Control terminal with the 4th switch unit 141 of color data line is connected to same data controlling switch.
As described above, secondary signal pin TP quantity is more than or equal to the quantity of touch-control handover module 130, that is,
Say, when array base palte includes at least one touch-control handover module 130, multiple touch-control handover modules 130 connect multiple the
Binary signal pin TP is part or all of secondary signal pin TP in whole secondary signal pin TP.
In the display stage, second controlling switch CKHR, CKHG, CKHB provides high level, and the first controlling switch successively
CKHM persistently provides low level, then multiple secondary signal pin TP pass through the 3rd switch unit 133 in touch-control handover module 130
Draw successively to red data line R, green data line G, blue data line B transmitting display data signals, and multiple secondary signals
Pin TP is by the 4th switch unit 141 in display control unit 140 successively to red data line R, red data line G, blueness
Data wire B transmitting display data signals, meanwhile, the first switch unit 131 turns on, the second switch unit 132 ends, and same first
Signal pins VCOM transmits common electrode signal to all touch control electrodes 110, wherein, the touch control electrode is used for self-capacitance
Touch-control.
In pre-detection stage, second controlling switch CKHR, CKHG, CKHB all provides low level, and the first control is drawn
Pin CKHM provides low level, then all 3rd switch units 133 and all 4th switch units 141 end simultaneously, the first switching
Unit 131 turns on, the second switch unit 132 ends, and same first signal pins VCOM transmits pre- to all touch control electrodes 110
Detection signal.
Pre-detection stage has been detected after touch occurs, then switchs to the touch control detection stage, the second controlling switch CKHR,
CKHG, CKHB all provide low level, and the first controlling switch CKHM provides high level, then all 3rd switch units 133
End simultaneously with all 4th switch units 141, meanwhile, the first switch unit 131 ends, the second switch unit 132 turns on, often
Secondary signal pin TP corresponding to one the second switch unit 132 transmits touching signals to corresponding touch control electrode 110 and received,
To position position of touch.Or if pre-detection stage is not detected by the generation of touch, switch to the display stage, show next frame
Picture.
Alternatively, touch-control handover module 130 is integrated on array base palte, and display control unit 140 is integrated in array base palte
Upper (as shown in Figure 5).Or control chip has been attached on array base palte, touch-control handover module 130 is integrated in control chip.
Secondary signal pin TP is used to pass by array base palte provided in an embodiment of the present invention, touch-control handover module in display
Defeated display data signal, it is used to transmit touching signals, therefore the part or all of secondary signal pin of control chip in touch-control
TP is multiplexed in display stage and touch control detection stage, saves the input/output pin of control chip.The present invention shows transmission
The pin multiplexing of data-signal is the pin of transmission touching signals, reduces the pin number of control chip, effectively reduces control
The size of chip, reduce array base palte cost.Meanwhile the present invention also carries out pre-detection, passed through before touch control detection
Same first signal pins VCOM sends pulse signal detection touch, is touched if existing, then defeated with secondary signal pin TP
Go out touching signals, confirm the position of touch point, if in the absence of touching, without touch control detection, effectively reduce array base palte
Power consumption.
The present invention has one embodiment also to provide a kind of self-capacitance touch control display apparatus, self-capacitance touch-control display dress
Put and be less than array base palte of the prior art including array base palte as described above, the cost and power consumption of array base palte as described above
Cost and power consumption, therefore the cost and work(of the self-capacitance touch control display apparatus provided by the invention comprising above-mentioned array base palte
Consumption is also corresponding to be reduced.
Pay attention to, above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious changes,
Readjust and substitute without departing from protection scope of the present invention.Therefore, although being carried out by above example to the present invention
It is described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept, also
Other more equivalent embodiments can be included, and the scope of the present invention is determined by scope of the appended claims.
