Background technology
The touch screen pattern of touch screen panel display apparatus mainly includes " resistive touch screen " and " capacitive touch screen ".
In " resistive touch screen ", two layers of conductive transparent indium tin oxidation material (ITO) is set respectively as X electrode
Layer and Y electrode layer are provided with the circuit structure of such as " four-wire ohm " between X electrode layer and Y electrode layer.Pass through Y electrode layer
The Y voltages of detected touch point, obtain Y coordinate；Simultaneously by the X voltages of X electrode layer detected touch point, X-coordinate is obtained.
In " capacitive touch screen ", transverse electrode and longitudinal electrode, two arrays of electrodes are made with indium tin oxidation material (ITO)
The place of intersection will form mutual capacitance namely this two arrays of electrodes has respectively constituted the two poles of the earth of mutual capacitance.Detect mutual capacitance size
When, lateral electrode sends out pumping signal successively, and longitudinal all electrodes receive signal, can obtain all transverse directions so simultaneously
With the capacitance size of longitudinal electrode joint.When finger touches capacitance plate, affect touch point nearby two electrodes it
Between coupling, so as to change the capacitance between the two electrodes.According to touch screen two-dimensional capacitance change data, Ke Yiji
Calculate the coordinate of each touch point.
In touch screen panel display apparatus, the X of contact is obtained, Y coordinate is divided into two steps：
Y coordinate is calculated, applies driving voltage V in Y+ electrodesdrive, Y- electrodes ground connection, X+ connect as exit measurement
The voltage of contact, due to ITO layer homogeneous conductive, contact voltage and VdriveThe ratio between voltage is equal to the ratio between contact Y coordinate and screen height.
X-coordinate is calculated, applies driving voltage V in X+ electrodesdrive, X- electrodes ground connection, Y+ connect as exit measurement
The voltage of contact, due to ITO layer homogeneous conductive, contact voltage and VdriveThe ratio between voltage is equal to the ratio between contact X-coordinate and screen width.
It can be seen that in touch screen panel display apparatus, arrangement is needed for receiving the source circuit for showing signal
(source IC) and for obtaining the touch-control circuit of contact coordinate (testpoint integrated circuit, TP IC).
However, in the prior art, the space shared by both circuits is very big, increase panel display apparatus volume and accordingly into
This.
