In touch-control display panel, relative to electric resistance type touch control display panel, capacitance type touch control display panel has service life length, light transmittance
Height can support the advantages that multi-point touch, become the hot spot of touch display technology.
Capacitance type touch control display panel can be divided into self-tolerant touch-control display panel and mutual capacitance type touch-control display panel.From appearance
Formula touch-control display panel is made of transverse electrode and longitudinal electrode.When detecting the touch of user, self-tolerant touch-control display panel
Transverse electrode and longitudinal electrode are scanned respectively, determine the lateral coordinates and longitudinal coordinate of touch location, respectively to obtain touch point
Position on a display panel.If self-tolerant touch-control display panel is by M transversal scanning electrode and N number of longitudinal scanning electrode structure
At using self-tolerant scanning mode to need the number that scans for M+N times, it is seen that self-tolerant touch-control display panel scanning times are few,
It is low in energy consumption.For self-tolerant touch-control display panel, if touch point is single-point, seat of the touch point in X-direction and Y direction
Mark be it is unique, still, if touch point there are two (or more) point, coordinate of each touch point in X-direction and Y direction be equal
It is not identical, it is easy to appear " terrible point ".By taking two touch points as an example, then each touch point has two in X-direction and Y direction respectively

(X2, Y2).However, there was only two groups of coordinates in this 4 groups of coordinates is the true coordinate of two touch points, in addition two groups of coordinates are constituted
So-called " terrible point ".
Mutual capacitance type touch-control display panel is made of transverse electrode and longitudinal electrode.With the area of self-tolerant touch-control display panel
It is not, will form capacitor at the crossover location of transverse electrode and longitudinal electrode.When the finger of user touches mutual capacitance type touching
When controlling display panel, it will affect between two electrodes (transverse electrode and longitudinal electrode) for constituting capacitor near touch point
Coupling, so that the capacitance between the two electrodes is changed, to detect the position of touch point.For example, mutual capacitance type is touched
Control display panel is made of M transverse electrode and N number of longitudinal electrode, and mutual capacitance type scanning mode is used to need the number scanned for M*
N times.As it can be seen that the multiple spot of touch-control display panel can be accurately determined using mutual capacitance type scanning compared with self-tolerant scanning mode
The touch point of touch-control, but power consumption can greatly increase.Therefore, how to make touch-control display panel and including the touch-control display panel
Touch control display apparatus have both from hold detection and mutual tolerance detection feature become research heat topic.
