Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Fig. 1 represents the structural representation of the array base palte described in the embodiment of the present invention.
Shown in Figure 1, array base palte comprises grid line 16 and data line 14, and the pixel electrode 10 be formed in pixel region that grid line and data line limit and thin film transistor (TFT) 12, array base palte also comprises: correspondence is parallel to grid line 16 and perpendicular to the line of induction 18 of data line 14, for when there being touch action, by carrying out the position that discharge examination determines touched point within the first period.
By the technique scheme of the present embodiment, on array base palte, corresponding grid line 16 arranges one group of line of induction 18, and the live width, shape etc. of the line of induction 18 can require to design according to IC.Touch method of work is: discharge after charging to the line of induction 18, and detect the discharge scenario of the line of induction 18, as shown in Figure 2, Fig. 2 represents the line of induction discharge examination oscillogram described in the embodiment of the present invention, if when having touch action, due to adding of C_finger, the electric capacity on the line of induction 18 is caused to increase, so discharge time increases.And the present invention utilizes LCD signal not have the vicissitudinous time to sense, and avoids LCD noise.
Alternatively, the line of induction 18 is arranged on above or below grid line 16.
Alternatively, the line of induction 18 has the first width and second width located vertical with data line 14, and the second width is greater than the first width.
In the technique scheme of the present embodiment, the line of induction 18 can width uneven, in the point of intersection with data line 14, it is slightly wide that the line of induction 18 can suitably be arranged, like this arrange benefit be increase inductance capacitance.
Preferably, the first period was the overlapping time of shared time between two adjacent data line signals and the not overlapping time between adjacent two gate line signals.
In the technique scheme of the present embodiment, in LCD drives, between two often adjacent data line 14 signals, all can there is the time (TP) that an electric charge is shared, for reducing power consumption; Between two often adjacent gate line 16 signals, have a nonoverlapping time (OE), for preventing the crosstalk of adjacent lines, (if lastrow gate is not before arriving shutoff, the input of one's own profession data signal will make lastrow gate charging by mistake.For preventing above-mentioned situation from occurring, the OE time is used to be turned off in advance by lastrow gate).The present invention utilizes the overlapping time (T) of these two timing of this TP and OE to carry out the discharge examination of the line of induction 18.Owing to being the touch mode of projected capacitive, the noise impact of LCD is large especially, so needs do not have to carry out touch scanning during change in voltage in each signal line of LCD (data, gate, Vcom etc.), to avoid the interference of noise to induced signal of LCD.
