On person's angular position, specifically as seen in figs. 8-10.
In practical applications, if at least two capacitance touching control end is four, four capacitance touching control ends are set
In seated position, a side being preferably provided in two long sides of mobile terminal and the short side to connect with the long side,
It and is specific such as Figure 11 in the both ends and short side for be arranged in same long side on the end position of long side one end
Shown, what wherein the black block in figure represented is capacitance touching control end.
In practical Ying Yingzhong, the main composition at capacitance touching control end is one piece of thin copper sheet, and mobile phone is needed from the appearance
Consider the problem, then need the plastics for covering needs on copper sheet to achieving the effect that beauty, allow finger or metal all
It is good conductor, when it is close to capacitance touching control physical button, by plane-parallel capacitor principle it is found that finger or metal
Will be in capacitor touch button internus in plane-parallel capacitor class capacitor, to there can be certain capacitance, the capacitor
Value is transferred to capacitance touching control chip by resistance R1 and R2, and wherein the effect of resistance R1 and R2 mainly has: 1. raise or lower
Driving capability；2.ESD (Electro-static Driven Comb) protection；The effect of capacitance touching control chip mainly obtains the change of capacitance touching control physical button
Change so that triggering interrupt signal gives central processing unit processing, when capacitance touching control chip gets the capacitor of capacitance touching control physical button
The variation of value will export interrupt signal to central processing unit, central processing will be by I2C signal after getting the interrupt signal
(i.e. SDA (data line)/SCL (control line) signal wire) obtains capacitance parameter value, and the meaning for reading capacitance parameter value is to obtain
The size of capacitance, so that whether the size of the interpretation capacitance can be used as trigger signal, when CPU gets interrupt signal
When, it will inform that there is capacitor key trigger action on software upper layer, which will be configured to fire by upper layer software (applications),
It is fire effect that the function of triggering at this time will be embodied on interface, to realize design experience from hardware, and non-through
Touch screen software control in normal situation, Fig. 8-11 are shown the mobile phone interface effect diagram of design, TOUCH 1 with
TOUCH 2 is capacitance touching control end, and the virtual key 3 of additional mobile phone screen increases game to realize really " four refer to " operation
Experience sense.
In conclusion the embodiment of the invention provides a kind of touch-control circuit, touch panel and mobile terminals, for existing
The touch-control circuit of Mobile phone touch control screen is difficult to realize operation, response while multioperation, and causes user's operation control experience bad
Defect, realize that the operation to user detects by the way that a touch-control circuit is arranged on mobile phone, user passes through to touch-control
The touch-control at the capacitance touching control end on circuit makes the capacitance parameter on capacitance touching control end generate variation, after detection unit reads variation
Capacitance parameter and touching signals, central processing unit reads the electricity on at least two capacitance touching control ends that detect of detection unit
Hold parameter, and judge whether capacitance parameter meets touch condition, interrupt signal is generated according to the result of judgement, and it is total on mobile phone
Touch control operation of the control module according to interrupt signal and user on touching display screen, generates corresponding game operation, thus
Realize to the touch control operation except screen operator, be realize three fingers it is above while operation, to be brought more preferably to user
Experience.
