Description
Technical field
The present invention relates to contact panel, is a kind of wire structures of contact panel concretely, utilizes the lead of flexible circuit board replacement glass substrate, or lead is passed to this glass substrate back side, to reach the purpose of the contact panel wiring that narrows.
Background technology
In recent years, the man-machine interface of thoughts and feelings formula, as: contact panel (Touch Panel), be widely used in GPS (GPS), PDA(Personal Digital Assistant), portable phone (cellular phone) and the palmtop computer electronic products miscellaneous such as (Hand-held PC), replaced traditional input media (as: keyboard and mouse etc.).Significantly change in this design has not only promoted the man-machine interface compatibility of above electronic installation, has more omitted traditional input media, vacates the large-scale display panel of more space mounting, makes things convenient for user's browsing data.
In general, traditional electric resistance touch-control panel is according to the different wiring mode of its automatically controlled circuit, can be divided into four lines (4Wire) again, different distribution forms such as five lines or six lines, with the five-line contact panel is example, as shown in Figure 1, the transparent conducting glass substrate 1 of contact panel (as: ITO Glass) is at four automatically controlled circuits and transparent conductive film (as: the ITO Film of X and Y direction, not shown in the figures) be used for detecting an automatically controlled circuit of the magnitude of voltage of (sampling) X and Y-axis, amount to 5 automatically controlled circuits, the edge that all is laid in contact panel is to the bezel locations of 11 of transparent active regions.When the user bumps this contact panel with finger or style of writing (supposing the position of touching P), the set control circuit of the circuit board of this contact panel is supplied 5 volts power supply to the two ends of the automatically controlled circuit on this transparent conducting glass substrate 10, and make another automatically controlled circuit 16 be in ground state (ground, the voltage that is two ends equals zero), at this moment, touch position P is because of the impedance generation pressure drop that changes, make the automatically controlled circuit on this transparent conductive film can be sampled to the magnitude of voltage of Y-axis to Vpy, otherwise, when the power supply of control circuit to 5 volts of the two ends of the automatically controlled circuit 14 of this transparent conducting glass substrate supplies, and make another automatically controlled circuit 12 be in ground state (ground, the voltage that is two ends equals zero) time, automatically controlled circuit on this transparent conductive film will be sampled to the magnitude of voltage of X axis Vpx, after the calculating contrast of the magnitude of voltage of Vpx and Vpy by control circuit, the position that can learn touched coordinate P rapidly.
Automatically controlled circuit 10 in addition, 12, an end of 14 and 16 connects lead 20 respectively, 22,24 and 26 other ends are then along the edge of this transparent conducting glass substrate 1 with transparent conductive film, extend to the same side of this transparent conducting glass substrate 1 and transparent conductive film, extend to till the central position of this side more sinuously, this lead 20 respectively, 22,24 and 26 the other end then is connected with an end of a flexible circuit board (not shown) respectively, the other end of this flexible circuit board then extends to outside the edge of this transparent conducting glass substrate 1 and transparent conductive film, and on the set control circuit of the circuit board that is connected to this contact panel, in other words, the lead 20 of this contact panel, 22,24 and 26 and automatically controlled circuit 10,12,14 and 16 wiring zone is on the bezel locations between this contact panel edge and transparent active region.
Because, the demand of progress constantly of the manufacturing technology of liquid crystal panel and big window, the frame design of liquid crystal panel comes narrower more, make the width of frame of contact panel to change along with the frame of liquid crystal panel, the related wiring zone of lead and automatically controlled circuit that makes sharply dwindles, and not only directly tests the ability of contact panel circuit design, even becomes the design obstacle, therefore, existing following several modes are used to solve the wiring problem that narrow frame brings:
1, the live width refinement reduces the wiring area.But this method has resistance to raise, and falls increase, makes signal attenuation, the shortcoming that is subject to disturb.In addition, the live width refinement increases difficulty of processing, and yields reduces.
2, overlapping circuit (make lead and automatically controlled circuit overlapping) reduces wiring area (as: No. the 544824th, Taiwan patent).This method raises lead and automatically controlled circuit short-circuit risks by overlapping circuit on the transparent conducting glass substrate, and difficulty of processing increases, and yields reduces, and increases working routine and time, and production cost raises.
The transfer portion intraphase conductor to transparent conductive film to reduce the wiring area.Because the transparent conductive film non-refractory, and the tack of the circuit that forms at transparent conductive film and permanance be not as being machined in transparent conducting glass substrate, and page or leaf has increases working routine and time, and production cost is raise.
Therefore, how to develop better structure, become a design and manufacturer important topic anxious to be solved of each contact panel now between narrow frame, to lay automatically controlled circuit and lead.
