Amendment, it is also possible to realize the application each claim technical scheme required for protection.
First embodiment of the present invention relates to a kind of screen module, with reference to as shown in Figure 1 to Figure 2.This reality
Mode of executing is implemented on the basis of electronic equipment, and electronic equipment can be mobile phone, panel computer, electricity
The terminal unit such as brain, intelligent television.
Screen module in present embodiment comprises: glass substrate 1, touch sensing layer 2, screen driving chip 3,
N bar detection line 4, N number of connection pin 5 and N number of detector unit 6, wherein, N is natural number.
In present embodiment, the concrete structure of screen module is: touch sensing layer 2 is laid on glass substrate 1,
N number of detector unit 6 is arranged in screen driving chip 3, N bar detection line 4 and N number of connection pin 5
The display functional areas that may be contained within touch sensing layer 2 are peripheral.Wherein, display periphery, functional areas is provided with N number of
Detection region, the position peripheral in display functional areas corresponding to each detection region, can be stored in advance in
In electronic equipment, each detection region is provided with a detection line, and in Fig. 2, dotted line indication region is detection region.
Wherein, each detection line 4 one end is all connected with earth terminal GND, and other end correspondence connects one
Connecting pin 5, there is a detector unit 6 each connection pin 5 corresponding connection, thus defines N bar and use
The detection circuit of micro-crack whether is there is in each detection region of detection.
In present embodiment, whether detector unit 6 is turned on by the detection line 4 that detection is corresponding, thus examines
Whether the detection circuit corresponding to survey turns on.Detector unit 6 comprises the first resistance and for drawing with being connected
The detection pin that foot 5 connects, first resistance one end is connected with detection pin, other end ground connection.Therefore,
Whether each detection region existing micro-crack when detecting, each detection circuit has two circuit branch,
As it is shown on figure 3, circuit branch is respectively as follows:
First branch road: detection pin--detection line 4--earth terminal；
Second branch road: detection pin--the first resistance R1--earth terminal GND.
Specifically, owing to when arranging detection line 4, the thinner thickness of detection line 4, therefore when certain
When there is micro-crack in detection region, then the detection line 4 in this region will disconnect, and detection line 4 will not be by
Conducting, now the first branch road is off, and the second branch road is in the conduction state.Otherwise, when certain
When detection region does not exists micro-crack, then detection line 4 is normal, and now the first branch road is in the conduction state,
Second branch road is off.Therefore, different according to the circuit branch turned on, the detection list caused
The detection parameter that unit obtains is different such that it is able to by the conducting of detection line 4 whether detection, in order to
In detecting whether the detection region burying this detection line underground exists micro-crack.
When practical operation, each connection pin 5 is applied by control panel driving chip 3 by each detection pin

Pacify * 600 kilo-ohms of-0=0.6 volts；
2, when detecting line 4 and turning on, voltage U0The resistance-0 of=detection electric current I* the first resistance R1；
Because the resistance of the first resistance R1 is far smaller than the resistance of detection line 4, when detection line 4 is corresponding
Detection region when there is not micro-crack, detection line 4 is not turned on, and the voltage U on detection pin is 0.6V；
Otherwise, when the detection region detecting line 4 correspondence exists micro-crack, detection line 4 turns on, and detects pin
On voltage be far smaller than 0.6V.So, detect the virtual voltage on detection pin by voltmeter
U1, by virtual voltage U1With theoretical value U0Compare, just may determine that whether detection line 4 turns on,
It is thus possible to according to the conducting of detection line 4 whether, detect whether the detection region of detection line 4 correspondence deposits
