The touch control display apparatus of plate.
Background technology
With developing rapidly for Display Technique, touch-control Display Technique is gradually in the life of people.Existing
In touch-control display panel, relative to electric resistance type touch control display panel, capacitance type touch control display panel has long lifespan, light transmittance
It is high, the advantages of multi-point touch can be supported, the focus as touch-control Display Technique.
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 up of transverse electrode with longitudinal electrode.When the touch of user is detected, self-tolerant touch-control display panel
Transverse electrode and longitudinal electrode are scanned respectively, the lateral coordinates and longitudinal coordinate of touch location are determined 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
Into using self-tolerant scan mode to need the number of times of scanning 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 is unique, but, if touch point have two (or more) point, coordinate of each touch point in X-direction and Y direction be equal
Differ, easily " terrible point " occur.By taking two touch points as an example, then each touch point has two respectively in X-direction and Y direction
Individual projection (for example, X1, X2 and Y1, Y2), such that it is able to be combined into 4 groups of coordinates, i.e. (X1, Y1), (X1, Y2), (X2, Y1) and
(X2, Y2).However, it is two true coordinates of touch point there was only two groups of coordinates in this 4 groups of coordinates, two groups of coordinates are constituted in addition
So-called " terrible point ".
Mutual capacitance type touch-control display panel is made up of transverse electrode with longitudinal electrode.With the area of self-tolerant touch-control display panel
It is not that can form electric capacity at the crossover location of transverse electrode and longitudinal electrode.Touched when the finger of user touches mutual capacitance type
During control display panel, can influence between two electrodes (transverse electrode and longitudinal electrode) for constituting capacitor near touch point
Coupling, so as to change the capacitance between the two electrodes, so as to detect the position of touch point.For example, mutual capacitance type is touched
Control display panel is made up of M transverse electrode and N number of longitudinal electrode, and it is M* to use mutual capacitance type scan mode to need the number of times of scanning
N times.It can be seen that, compared with self-tolerant scan mode, the multiple spot of touch-control display panel can be accurately determined using mutual capacitance type scanning
The touch point of touch-control, but power consumption can be greatly increased.Therefore, touch-control display panel how is caused and including the touch-control display panel
Touch control display apparatus have concurrently from hold detection and mutual tolerance detection feature turn into research heat topic.
