Detailed description of the invention
Embodiment one
As shown in Figures 1 to 3, the key-press module of the soft icon of the mobile phone of the present embodiment is arranged under mobile phone
The glass cover-plate back side in portion's (direction of arrow as depicted is bottom), a FPC of key-press module
(flexible PCB) circuit 11 passes through first with the 2nd FPC circuit 4 of the LCM module of mobile phone
Data signal transmission wire connects, and a FPC circuit 11 and the 2nd FPC circuit 4 share the second number
According to signal transmssion line, the second data signal transmission wire 12 is between LCM module and cell phone mainboard
The transmission of signal data.
LCM module mentioned here, contains the display screen 1 and LCM mould of LCM module
The parts such as the 2nd FPC circuit of block.As it is shown in figure 1, a FPC circuit 11 of key-press module
Data signal transmission wire 6 be folded upward at from the right side of Fig. 1, guide to the second of LCM module
The line interface 10 of FPC circuit 4, this line interface FPC circuit 4 and LCM by LCM
Second data signal transmission wire 12 of module connects.The second data between LCM and cell phone mainboard
Signal transmssion line 12 is normal structure, in specification example have 50PIN, 70PIN etc. (include 50,
70 lead-in wires), these circuits typically have redundancy that can be certain, and amount of redundancy is substantially at 10 lead-in wires
Above.Oneth FPC circuit of key-press module, the number of leads related to generally comprises: 3 LED
Supply lines, 2-3 root push button signalling line, more superfluous owing to existing in the second data signal transmission wire
Remaining lead-in wire, therefore, is fully able to accommodate signal and the transmission of data of a FPC circuit.Need
Illustrating, the first above-mentioned data signal transmission wire and the second data signal transmission wire all can be adopted
By the structure of flexible PCB.
Therefore, the key-press module of the soft icon of mobile phone of the present embodiment, by by a FPC circuit 11
It is connected by the first data signal transmission wire with the 2nd FPC circuit, and allows a FPC circuit 11
Share the second data signal transmission wire with the 2nd FPC circuit 4, thus decrease on cell phone mainboard
Line interface, i.e. decreases original and key-press module a FPC circuit and carries out data and signal biography
Defeated interface circuit, thus decrease the complexity of motherboard circuit, too increase sky, bottom simultaneously
The headroom in line region.Preferably, the line interface of a FPC circuit is arranged at the one of key-press module
Side, so convenient the 2nd FPC circuit lead with LCM, and do not affect in the middle part of mobile phone
Circuit layout.
Further, key-press module specifically may include that soft icon silk-screen symbol 9, is printed on glass
Cover plate 3 back side；LED 2, arranges the both sides in the region that key-press module covers；Oneth FPC electricity
Road 11, electrically connects with LED 2；Periphery at soft icon silk-screen symbol 9 is electroplate with silver serous coat electricity
Road 8, this silver serous coat circuit 8 electrically connects with a FPC circuit 11, is used for triggering push button signalling.
Further, between LED, post light guiding film, outside light guiding film, post photomask, guide-lighting
Film covers soft icon silk-screen symbol.
Based on said structure, the operation principle of the soft icon button of the present embodiment is as follows: mobile phone power-on
After, the LED at three soft ICON (three soft icon silk-screen symbols as shown in Figure 2) two ends
Luminescence, leads through light guiding film and lights to three soft ICON, during finger trigger ICON, cause glass
On panel, the silver-colored serous coat capacitance variations of plating produces signal feedback, and signal is passed to soft through silver serous coat circuit
The oneth FPC circuit of ICON, then the second of LCM is passed to by the second data signal transmission wire
FPC circuit, is finally passed through hand by signal via the second data signal transmission wire by the 2nd FPC circuit
Mainboard passes to mobile phone CPU process.
As structurally another of the present embodiment change important enter a little, can be by a FPC circuit
11 are arranged between LCM module and glass cover-plate (such as the view of Fig. 1 and Fig. 2, LCM module
Oneth FPC circuit 11 is covered), and light guiding film and photomask are positioned at the bottom of LCM module.
The most as shown in Figure 4, it show separately the shape and structure of a FPC circuit, a FPC
Circuit mid portion is embedded between LCM module and glass cover-plate, and two ends are stretched out and LED
Connecting circuit part, mid portion is connected with the silver serous coat circuit that connects through of soft ICON button.
Such structure, has been placed in a FPC circuit between LCM module and glass cover-plate,
The circuit exposed of mobile phone bottom further reduces, thus adds antenna for mobile phone region, bottom
Headroom, improves the utilization ratio of antenna.
