In the present embodiment, multiple pressure sensitive units 20 are arranged in array so that multiple pressure sensitive units
20 the first output end a, second output terminal b, first input end d and the second input terminal c is believed by the data line 31 or pressure
Number line 40 and the trace arrangements when pressure-driven circuit connection are more neat, reduce the difficulty of trace arrangements.
In addition, in the case that multiple pressure sensitive units 20 are arranged in array, when the flexible base board 10 is due to outer
Boundary's pressure and when bending, multiple pressure sensitive units for being set on one or more straight line of the part that bends
Consistency variation occurs for the pressure sensitive signal of 20 outputs, when the flexible base board 10 is recessed due to ambient pressure,
It is set to and the pressure sensitive signal generation specificity that the one or more pressure sensitive unit 20 of depressed section exports occurs
Variation, in this way can be by being arranged relevant algorithm for the flexible base board 10 since ambient pressure bends and is recessed
The case where distinguish, and then realize richer pressure touch function.
First input end d and the same data along the column pressure sensitive unit 20 in 31 direction of data line
Line 31 connects, along the second input terminal c and the same number of the column pressure sensitive unit 20 in 31 direction of data line
It is connected according to line 31, the first input end d and the second input terminal c are connected respectively at different data line 31；
Along the first output end a and the different numbers of the column pressure sensitive unit 20 in 31 direction of data line
It is connected according to line 31, along second output terminal b and the different institutes of the column pressure sensitive unit 20 in 31 direction of data line
State the connection of data line 31.
It should be noted that in other embodiments of the invention, as shown in Figure 10, Figure 10 is another reality of the invention
The connection type in a kind of pressure sensing cell array of example offer along a column pressure sensitive unit 20 in data line direction is applied to show
It is intended to, along the first input end d and same first letter of the column pressure sensitive unit 20 in 31 direction of data line
Number line 41 connects, along 31 direction of data line a column pressure sensitive unit 20 the second input terminal c with it is same described
Second signal line 42 connects；
Along the first output end a and the different numbers of the column pressure sensitive unit 20 in 31 direction of data line
It is connected according to line 31, along second output terminal b and the different institutes of the column pressure sensitive unit 20 in 31 direction of data line
State the connection of data line 31.
In this way, even if the first input end d of the pressure sensitive unit 20 and the second input terminal c do not pass through multiplexing described the
Three data lines 313 and the 4th data line 314 are connect with the pressure-driven circuit 50, and one along 31 direction of data line arranges institute
