Hereinafter, describe signal pattern structure as the single-layer touch sensor of exemplary embodiment of the invention in detail with reference to accompanying drawing.
The present invention relates to a kind of signal pattern structure of single-layer touch sensor, this single-layer touch sensor has the X-axis sensing element 100 of sensing X-axis touch signal and the Y-axis sensing element 110 of sensing Y-axis touch signal, wherein, conductive pattern 130 a layouts direction in the plane that is used for Y-axis sensing element 110, the conductive pattern that is used for the X-axis sensing element, with the conductive pattern 130 relative (opposite of Y-axis sensing element 110, be patterned on the direction on the contrary), edge along touch sensor is patterned in the direction identical with the conductive pattern that is used for Y-axis sensing element 110 then, those X-axis conductive patterns 120 with different X-axis values are patterned as bridge joint, and those X-axis conductive patterns 120 with different Y-axis values are patterned as and are not connected.
In the signal pattern structure of single-layer touch sensor, purport of the present invention is by the needed space of minimum conduction pattern, makes things convenient for design and implementation space efficient.
At first, provide the description of the necessity of signal pattern structure of the present invention.When touch sensor was applied to the digital device of or intelligent panel computer auxiliary such as smart mobile phone, PDA, navigation, it was formed according to display sizes, and conductive pattern is connected to touch sensor to transmit the electric signal of touch sensor.Here, conductive pattern is connected to the input terminal that touches IC and touches IC and carry out signal and handle being sent to by the electric capacity (being touched the electric capacity that causes by the user) of touch sensor sensing.That is, conductive pattern is concentrated towards input terminal.Therefore, need solve the problem of limited space by the quantity that minimizes the conductive pattern that concentrates on a direction.
Fig. 2 shows the signal pattern structure according to single-layer touch sensor of the present invention.With reference to Fig. 2, in the touch sensor configuration: touch sensor 300 is made by the ITO film, is configured to X-axis and the Y-axis coordinate of sensing user touch location; Be used for being formed on touch sensor 300 at the X-axis sensing element 100 of sensing signal on the X-direction with for the Y-axis sensing element 110 of sensing signal on Y direction; The Y-axis conductive pattern 130 that is used for Y-axis sensing element 110 is disposed in a direction on plane, the X-axis conductive pattern 120 that is used for X-axis sensing element 100 is patterned in the direction relative with the Y-axis conductive pattern 130 that is used for Y-axis sensing element 110, be patterned in the direction identical with the conductive pattern 130 that is used for Y-axis sensing element 110 along the edge of touch sensor then, and those X-axis conductive patterns 120 on X-direction are bridged.
That is, for X-axis sensing element 100 sensing signals from the sensing element that is arranged in X-direction and Y direction, the X-axis conductive pattern 120 on the X-direction is bridged and forms a conductive pattern.For example, among Fig. 2, all the sensing element x0 in the X-axis sensing element connect by identical pattern.Thus, (duplicated) pattern of coincidence is merged into a pattern, has reduced pattern width.
Than the touch sensor arrangement of Fig. 1, significantly reduce in the quantity of the conductive pattern of left side patterning.The invention solves the correlation technique problem among Fig. 1---because the conductive pattern that is connected with the X-axis sensing element all formation on X-direction and Y direction, so conductive pattern has occupied big quantity space.
For the X-axis conductive pattern being engaged to the touch sensor 300 that uses pattern plate, contact point 210 is formed on bridging board 200 and the touch sensor 300.That is, X-axis conductive pattern and touch sensor 300 engage by contact point 210.
Here, the conductive pattern in left side can be done as a wholely with common formation of touch sensor 300, and can engage with the bridging board that wherein forms the X-axis conductive pattern.
Fig. 3 is the partial enlarged view of bridging board 200 in the signal pattern structure.As shown in Figure 3, contact point 210 is formed on bridging board 200 and the touch sensor.Here, bridging board 200 has sandwich construction, to prevent the contact between different conductive patterns.Bridging board 200 is connected with touch sensor by the joint at contact point 210 places.
