Abstract
The invention relates to a touch pad layout method and a layout structure thereof. The layout method comprises the following steps: determining a frame size along the X axis and the Y axis; calculating the number of scanning lines on a touch pad; calculating the side length and included angle of a hexagon according to the conditions; and determining the layout of the whole touch pad according to the size of the hexagon. The touch pad layout method and the layout structure thereof facilitate the overall layout. Since no clearance can be caused between patterns, the layout method has high anti-interference capability. Moreover, due to the compact layout of the touch pad, the sensed signal is more intense.
Description
Technical field
The present invention relates to a kind of layout method and layouts thereof, refer in particular to a kind of layout method and layouts on Trackpad.
Background technology
Along with the continuous progress of science and technology, the touch panel that in the past was used on the large scale electronic equipment has been widely used on many small-sized portable electronic devices.After having had touch panel on the electronic installation, can simplify procedures, the program of electronic operation is more prone to and easy.Simultaneously, under the application of touch panel, can allow number of keys reduces on the operation interface of electronic installation, thereby increase the display area of display screen, can certainly dwindle the volume of electronic installation, so that carry.
Because above-mentioned advantage, Trackpad has been widely used on the electronic product such as portable notebook.But up to the present, the structure of Trackpad is mostly more single, as shown in Figure 1, as can be seen from the figure, the Butut mode of its rhombus can well reduce stray capacitance (so-called stray capacitance is the edge capacitance that forms) between driving and sensing unit, increase advantages such as inductance capacitance, but its antijamming capability is limited, and under the condition that changes in environment temperature, humidity, the environment of electric field ratio is easier to change, very easily cause drift, cause unnecessary maloperation.
Therefore need solve above problem for users provide a kind of easier method.
Summary of the invention
The actual technical matters to be solved of the present invention is how a kind of new Trackpad layout method and layouts thereof are provided, and it is not only simple in structure, and can guarantee that induced signal is strong and have stronger antijamming capability.
In order to realize above-mentioned purpose of the present invention, the invention provides a kind of touch pad layout method, it may further comprise the steps: the frame size of determining X-axis and Y-axis; Calculate the bar number of Trackpad upper tracer; Calculate hexagonal length of side and angle according to above-mentioned condition; Thereby determine the Butut of whole touch pad according to hexagonal size.
The invention still further relates to a kind of Butut of Trackpad, described Trackpad contains several hexagons and sweep trace, and the sweep trace on the Trackpad is used to scan X-axis and Y-axis, and the cross arrangement of described hexagon difference is on two axles.
Touch pad layout method of the present invention and layouts thereof, not only whole Butut is convenient, and this Butut mode, owing to do not have the gap between the figure, so antijamming capability is very strong; Moreover, because the compact in design of its Trackpad, so induced signal is stronger.
Description of drawings
Fig. 1 is the layouts of existing Trackpad;
Fig. 2 is the process flow diagram of Trackpad step of the present invention;
Fig. 3 is the Butut embodiment of Trackpad of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Please refer to shown in Figure 2ly, be flow chart of steps of the present invention, in order to guarantee the antijamming capability of Trackpad, we wish that the figure on the Trackpad is compact as much as possible, so we need at first to determine the frame size of Trackpad; Determine the bar number of Trackpad upper tracer then, obtain just can determine under the prerequisite of optimum resolution the numerical value of described Trackpad upper tracer in the display device that guarantees to make described electronic equipment; According to the bar number of the frame size of described Trackpad and sweep trace just can calculate hexagonal length of side and between angle, can determine the Butut of whole touch pad thus.
Below we are concrete again discusses down how to determine hexagonal length of side and angle according to the size of Trackpad upper side frame and the bar number of sweep trace.Please refer to shown in Figure 3ly, suppose that the frame size of this Trackpad on X-direction is Wx, the frame size on Y direction is Wy; Described Trackpad is Nx at the bar number of X-axis upper tracer, and is Ny at the bar number of Y-axis upper tracer, and a hexagonal angle is
If θ is its half angle, i.e. angle
So according to leg-of-mutton Computer Corp. as can be known: X-axis upper side frame size is: Wx=2x*n
xThe size of Y-axis upper side frame is:
Angle
We finally just can determine this hexagonal length of side and angle by above-mentioned formula.After having determined above-mentioned numerical value, thereby we just can determine the Butut of whole touch pad according to its hexagonal size.In the above-mentioned argumentation, the big I of the frame of X-axis and Y-axis is set in advance on the Trackpad, and the bar number of described Trackpad upper tracer is relevant with the exploration on display resolution ratio of the electronic equipment that is equiped with Trackpad.
Below we continue to discuss down and have determined the Butut that how to carry out Trackpad after hexagonal size again.Because hexagonal size and angle are all determined, so now adjacent hexagons can be staggered, even a certain hexagonal edge on any one hexagonal edge on the X-axis and the Y-axis is adjacent.Described six distortion on X-axis and Y-axis connect by bridge joint respectively, all are insulation courses in the middle of its any adjacent hexagons, as being the silicon dioxide etc. with insulating effect.Butut is not only convenient like this, and since its compact conformation so induced signal is stronger, and because the layout between adjacent hexagons edge and the edge is very close to each other, so also increased the antijamming capability of this Trackpad.
Touch pad layout method of the present invention and layouts thereof, not only whole Butut is simpler, and has adopted hexagonal special construction, and having guaranteed does not have the gap between the figure, so antijamming capability is very strong; Moreover, because the compact in design of its Trackpad, so induced signal is also stronger.
