Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing and not all.
It should be noted that, the touch-control scan method that the embodiment of the present invention provides, be applicable to touch-control scanning and there is with reading scan the touch-control display panel interfered with each other, be particularly useful for touch controllable function layer and Presentation Function layer has multiplexing touch-control display panel, as shown in Figure 1, wherein multiplexing public electrode is touch-control drive electrode, and therefore when reading scan, drive IC needs to provide common electrode signal Vcom needed for display to public electrode; When touch-control scans, drive IC needs to provide drive singal needed for touch-control to public electrode, drive IC detects the signal of touch-control sensing electrode RX simultaneously, to have judged whether that touch-control action occurs, also namely touch-control scanning refers to touch-control drive electrode input sweep signal, detects the signal intensity of touch-control sensing electrode.Preferably, reading scan and touch-control scan timesharing and perform.In addition, under normal circumstances, before the scanning of execution touch-control or after all touch-control drive electrodes complete touch-control scanning, drive IC can perform noise (Noise) scanning, also, namely when touch-control drive electrode does not input sweep signal, the signal of touch-control sensing electrode is detected.In the normal situation of touch controllable function, now detection signal does not change, otherwise needs to regulate touching signals threshold value, initialization touch-control system.The time of a noise scanning is longer than the time of a scanning touch-control drive electrode.Usually, a noise scanning scans a touch-control scan period of formation with the touch-control of all touch-control drive electrodes, and conventional display frequency is 60HZ, and touch-control frequency is 120HZ, during also namely a frame shows, has needed two touch-control scan periods.Preferably, noise scanning performs with reading scan also timesharing.
The driver' s timing of above-mentioned panel construction, generally that gate line is divided into some groups, one group comprises m root gate, after scanning one group of gate line, carry out the scanning of touch-control drive electrode TX, the direction of usual gate line scanning is contrary carrying out with the direction of scanning of touch-control drive electrode TX, and such as gate line from top to bottom scans, then touch-control drive electrode TX scans from the bottom to top.After completing all touch control electrode TX and scanning, (Nosie scanning refers to when not applying sweep signal to touch-control drive electrode TX to carry out a Noise scanning, detect the signal of touch-control sensing electrode RX), or before touch-control drive electrode TX starts scanning, carry out a Noise scanning.When carrying out order and scanning, when the position that position and the touch-control drive electrode TX of gate line scanning scan overlaps, also certain a line gate line generation On/Off action of i.e. touch-control drive electrode TX covering, now, the scanning motion of gate line can produce noise signal interference to the touch-control drive electrode of overlap, makes touch control detection result not accurate, causes the touch-control sensitivity decrease of touch-control display panel, the requirement application of high touch-control can not be realized, as gloves, waterproof etc.
Fig. 3 B is depicted as the driver' s timing figure of touch-control display panel routine, touch-control display panel corresponding to Fig. 3 B as shown in Figure 3A, Fig. 3 A is only in order to the simple case that conventional driver' s timing is enumerated is described, this panel has 16 row gate lines, article one, touch-control drive electrode covers four gate lines, the frequency of touch-control scanning is identical with reading scan frequency, is 60HZ.Under normal circumstances, noise is the several times of the sweep time of single touch-control drive electrode sweep time, supposes that noise is equivalent to the sweep time of four times of wall scroll touch-control drive electrodes sweep time.As shown in Figure 3A, within the reading scan cycle that a frame is complete, before touch-control drive electrode starts scanning, advanced Row noise scanning.Due to 4 times that noise is wall scroll touch-control drive electrode sweep time sweep time, then every two row gate lines scannings, carry out a noise scanning or TX scanning.Therefore, after G1 ~ G2, G3 ~ G4, G5 ~ G6, G7 ~ G8 reading scan complete, noise scanning is carried out.Suppose that reading scan is contrary with the direction that touch-control scans, then, after G9 ~ G10 reading scan, touch-control scanning carried out to the first touch-control drive electrode TX1, after G11 ~ G12 reading scan, touch-control scanning is carried out to the second touch-control drive electrode TX2.Now, due to the second touch-control drive electrode TX2, to cover G11 and G12 capable, therefore G11 and G12 is when reading scan, signal in its gate line can change, namely there is the process of opening and closing, can produce interference to the touch-control scanning of the second touch-control drive electrode TX2, the On/Off process that especially the capable gate line of G12 occurs can produce interference to the touch-control scanning of TX2, causes touch-control result inaccurate.Owing to there is overlap physically in G11, G12 and TX2, and the touch-control of the reading scan of G11, G12 and TX2 scans and occurs in herein, defining this kind of situation is that touch-control scanning occurs in overlapping touch-control drive electrode and gate line with scan simultaneously, and " simultaneously " also namely in the present invention refers to the touch-control drive electrode at physical overlap place and gate line execution touch-control scans and reading scan.Normal conditions, in a frame display cycle, reading scan and touch-control scan the number of times of gate line and the touch-control drive electrode occurring in overlapping place, are determined by display frequency and touch-control frequency.Suppose that display frequency is 60HZ, touch-control frequency is 60HZ, then can occur once in a frame; If touch-control frequency is 120HZ, then can occur twice.
