Embodiment
The utility model scheme makes the touch pad of electronic equipment have soft key function mainly by electronic equipment is provided with, and that is to say, the user can realize the input of soft keyboard by touch pad.This just requires when needs use soft keyboard, and touch pad can demonstrate the pairing key information of each enter key, to allow the user carry out the input of soft keyboard according to key information.
At above-mentioned requirements, the utility model scheme provides circuit structure as shown in Figure 1.At first in electronic equipment, increase soft keyboard and select module 101, light emitting module 102, and on the touch pad at the key-press module 103 of set soft keyboard.
Wherein, it specifically can be a functional module that is realized by software that set soft keyboard is selected module 101, also promptly send signals such as opening or close to central processing module, specifically can be set to by the start default mode, or enter the soft keyboard pattern by mouse control by software; Also can be arranged on the button on the electronic equipment, send signals such as opening or close to central processing module by circuit signal.
Set light emitting module 102 can be arranged on the back of touch pad 104, is used for the key information of set soft keyboard is shown from touch pad 104.
In addition, also to the central processing module 105 of electronic equipment be provided with, on the touch pad 104 of electronic equipment, soft keyboard to be set by central processing module 105, and make and when the user selects module 101 to select the soft keyboard patterns by soft keyboard, open soft key function, when withdrawing from the soft keyboard pattern, the user closes soft key function.And by central processing module 105 control light emitting modules 102, central processing module 105 can be controlled to be the duty of light emitting module: open light emitting module 102 when the user selects the soft keyboard pattern; When withdrawing from the soft keyboard pattern, the user closes light emitting module 102.
In addition, same as the prior art, central processing module 105 can pass through data signal line X+, Y+, X-and Y-equally and receive the data-signal that touch pad 104 sends, and chooses touch pad 104 by two I2C bus signals SCL and SDA control.
In the circuit structure shown in Figure 1, the relevant control circuit of set light emitting module, also be touch pad keyboard pilot lamp control circuit as shown in Figure 2.Wherein, central processing module 105 can be controlled light emitting module 102 by an electric current and voltage control module, present embodiment specifically is by an adjustable voltage control module, the power supply signal VDD that is 201 pairs of light emitting modules 102 of adjustable voltage controller (LDO) controls, and LDO 201 specifically to be VDD by VOUT control light emitting module 102 open or close.
Specifically, central processing module 105 can send corresponding level signal by the input control pin SHDN_N of pin GPIO able to programme in LDO 201 of self when determining to open light emitting module 102.When the level signal of central processing module 105 input LDO 201 was high level, LDO 201 closed output voltage VO UT; When level signal was low level, LDO 201 opened VOUT, the output predetermined voltage source.
The used touch pad of the utility model can adopt circuit as shown in Figure 3; Used light emitting module also promptly then can adopt as shown in Figure 4 circuit at the pilot lamp of soft keyboard.Certainly, these two modules also can adopt other circuit form, as long as can realize function separately.
By above-mentioned setting, electronic equipment is under the situation of not opening the soft keyboard pattern, and light emitting module can be in off working state, without any demonstration, can realize mouse beacon track etc. and existing electronic equipment identical functions easily on the touch pad.And if the user selects module to select to enter the soft keyboard pattern by soft keyboard, then central processing module can obtain starting the control signal of soft keyboard pattern, central processing module can send corresponding enabling signal to light emitting module afterwards, start light emitting module to demonstrate the key area, start corresponding software programs simultaneously, with the response soft keyboard input mode.
After light emitting module was opened, the user can be according to shown key area and the needs of self input key information.Touch pad then can send to central processing module with the signal of user's input; Since before started the software program that is used to respond soft keyboard input mode, so the signal that central processing module sends according to touch pad determines the key information that the user imports, and carries out corresponding operation, thereby realizes soft key function.
After the user selects module to withdraw from the soft keyboard pattern by soft keyboard, central processing module then can send shutdown signal to light emitting module according to the signal that withdraws from that soft keyboard selects module to send, closing light emitting module, and withdraw from the software program corresponding with soft keyboard input mode.
In addition, the utility model can have multiple keyboard mode by the soft keyboard of central processing module setting.Such as, numeric keypad pattern or alphabetic keypad pattern can be set, this two kinds of keyboard modes also can be set simultaneously, certainly, the keyboard mode of other types can also be set as required.A kind of soft keyboard structure that is under the alphabetic keypad pattern shown in Figure 5.
Different keyboard modes is set then needs to be provided with corresponding Keysheet module and light-emitting device, and indicates inhomogeneous key assignments by opening different light-emitting devices.No matter the how many kinds of keyboard mode is set, it realizes that principle is identical.Certainly, if a kind of keyboard mode only is set, then light emitting module can be in opening always; If but were provided with multiple keyboard mode simultaneously, then after certain keyboard mode was closed, for not influencing user's use, the light emitting module corresponding with this keyboard mode also should be closed.
The above only is the preferred embodiment of the utility model scheme, not in order to limit protection domain of the present utility model.
