Description
Technical field
The present invention relates to the touch-screen detection field, particularly relate to a kind of method of testing and device of touch-screen precision.
Background technology
Touch screen technology is more and more should be in computing machine, portable terminal and various handheld device.It is simple, convenient, the most natural present a kind of man-machine interaction mode.The user only need touch icon or literal gently, just can realize the operation to equipment.
In the property indices of touch-screen, precision is most important one, directly has influence on result of use and the customer experience of touch-screen.Precision reflection contact and touch-screen response light target deviation, the designing requirement of touch-screen and offering in user's the technical documentation all has this index.Precision more and more extensively is used for assessing the performance quality of touch-screen by the user.
Existing method of testing adopts the subjective evaluation method more and clicks detection method.Whether the subjective evaluation method is randomly drawed the part point by the tester at contact panel, identical with contact position by observing the contrast response point.The subjective evaluation method exists the test point that extracts can not be evenly distributed to whole contact panel, and the naked eyes contrast is difficult for finding out nuance.Click detection method by tester's button click or icon, determine whether to realize corresponding function, click the difference of the more difficult discovery response point of detection method and contact position.
Above two kinds of methods all can't accurately be tested the precision of touch-screen.
Summary of the invention

Embodiment
The present invention will be described below in conjunction with accompanying drawing.
The present invention proposes a kind of method of testing of touch-screen precision, please refer to Fig. 1, comprises step:
S101, set up virtual grid at touch-screen, take the intersection point of virtual grid as test point;
Set up the step of virtual grid, can be: according to diameter, the number of checkpoints of the touch object of inputting, set up virtual grid at touch-screen, test point be positioned at grid intersection.The test point size is identical with the diameter that touches object, and the number of test point is identical with input value, and is evenly distributed on effective Petting Area of whole contact panel.Each test point has a theoretical coordinate value.A schematic diagram of the virtual grid of setting up can be referring to Fig. 2, and dot is the intersection point of virtual grid among the figure, namely is test point.Grid configuration, the mesh-density set up can change as required.
The real-time coordinate of S102, touch-screen response when obtaining each test point of click;
When clicking each test point, corresponding each click action has individual real response position on the touch-screen, and the coordinate of this real response position is real-time coordinate, the corresponding real-time coordinate of test point of every click.
The difference of S103, each real-time coordinate of comparison and the theoretical coordinate of corresponding test point;
For example, the real-time coordinate of one of them test point is (X1, Y1), the theoretical coordinate of this test point is (X0, Y0), when then carrying out the comparison of S103 step, one of them manner of comparison is: in real time coordinate deducts theoretical coordinate and obtains its difference and be (X1-X0, Y1-Y0).
S104, judge according to each difference whether the precision of touch-screen meets the demands;
Concrete, this step comprises: the size of each difference and default permissible value relatively; Obtain difference less than the ghreshold numbers of default permissible value; Should default permissible value can be a definite numerical value, also can be a numerical range.
When the maximal value of difference less than default permissible value, and ghreshold numbers then meets the demands when accounting for all number of test points purpose ratios and being greater than or equal to predetermined ratio; Otherwise ghreshold numbers accounts for all number of test points purpose ratios less than predetermined ratio, does not then meet the demands.
For example: default permissible value is (0.3,0.3); Default ratio is 1/2; The test point number is 100; Calculating through the S103 step obtains test result, 3 groups of data: mode relatively can be referring to step S103, when X1-X0 and Y1-Y0 satisfy default permissible value respectively, just thinks to meet the demands; Concrete, the number that the 1st group of difference with theoretical value is (0.2,0.1) is 60; The number that the 2nd group of difference with theoretical value is (0.4,0.4) is 30; The number that the 3rd group of difference with theoretical value is (0.5,0.4) is 10; In the 1st group, 0.2 less than 0.3 and 0.1 less than 0.3, and then difference (0.2,0.1) meets the demands less than default permissible value (0.3,0.3); Then ghreshold numbers is 60, and it is 60/100 that ghreshold numbers accounts for total number of test points purpose ratio, and greater than 1/2, therefore, the touch precision of this touch-screen satisfies estimates requirement.
S105, send different alarms according to different judged results.
Concrete, this step comprises: when judged result when meeting the demands, send green alarm; When judged result when not meeting the demands, send the red alarm prompting, hummer yowls; Alarm is that the color of sending also can change other color into, as long as can distinguish different judged results.
Show that each difference, corresponding test point number and the ghreshold numbers of each difference account for all number of test points purpose ratios, and show other related datas.So that the testing staff in real time, get information about the test case that touch-screen touches precision.
The present invention also proposes a kind of proving installation of touch-screen precision, please refer to Fig. 3, comprising:
Virtual grid is set up unit 301, is used for setting up virtual grid at touch-screen, take the intersection point of virtual grid as test point; Virtual grid is set up unit 301 and is set up virtual grid according to the test point number of input and the size of test point; The intersection point in the same size of test point size and virtual grid, virtual grid is evenly distributed on touch-screen;
The real-time coordinate acquiring unit 302 of test point is used for obtaining the real-time coordinate of touch-screen response when clicking each test point;
Comparing unit 303 is used for the difference of each real-time coordinate relatively and the theoretical coordinate of corresponding test point;
Concrete, judging unit 304 is the size of each difference and default permissible value relatively, obtains difference less than the ghreshold numbers of default permissible value; When ghreshold numbers accounts for all number of test points purpose ratios and is greater than or equal to predetermined ratio, then meet the demands; Otherwise, do not meet the demands.
So that the testing staff in real time, get information about the test case that touch-screen touches precision, the proving installation of touch-screen precision also comprises display unit 306;
Please refer to Fig. 4, when the judged result of judging unit 304 when meeting the demands, alarm unit 305 sends green alarm; When judging unit 304 when judged result when not meeting the demands, alarm unit 305 sends the red alarm prompting, hummer yowls;
The present invention is by clicking at the intersection point of the virtual grid that produces, and when obtaining the click test point with this, the real-time coordinate of touch-screen response position contrasts this real-time coordinate with the theoretical coordinate of corresponding test point, thus the precision in the time of can quantizing the touch-screen touch; Compare precision when having improved the touch-screen detection with traditional detection method of touch screen.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
