Background technology
At present, existing touch-screen is mainly projected capacitive, and it is divided into mutual capacitance type according to scan mode
And self-capacitance (Self-Capacitance) (Multi-Capacitance).Wherein, the touch-screen of self-capacitance
Laterally and longitudinally electrod-array is typically fabricated to using transparent conductive material (such as ITO), these are laterally and vertical
To electrode respectively with ground constitute electric capacity, when finger touches touch-screen, the electric capacity of finger will be added to
In screen body capacitance, increase screen body capacitance amount.
In touch detection, the touch-screen of self-capacitance detects laterally and longitudinally electrod-array, root respectively successively
According to the change of electric capacity before and after touching, lateral coordinates and longitudinal coordinate are determined respectively, be then combined into touching for plane
Touch coordinate.The scan mode of self-capacitance touch screen, X is projected to equivalent to the touch point on touch-screen respectively
Axle and Y direction, then calculate coordinate in X-axis and Y direction respectively, are finally combined into touch point
Coordinate.Therefore, if there are two touches and on the touchscreen at this 2 points not in same X-direction or
During same Y direction, then there are two projections respectively in X-axis and Y direction, be combined into four coordinates, show
So, only two coordinates are real, and two other coordinate is exactly " the terrible point " being commonly called as, it is impossible to realized true
Multi-point touch effect.
