Embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
Please refer to Fig. 1, this Figure 1 shows that the process flow diagram of inventive touch screen method of testing first embodiment.
The principle schematic of composition graphs 3, the process that Fig. 1 embodiment is tested touch-screen is specific as follows:
Step 101: flow process starts.
Step 102: show multiple touch area on the touchscreen.
This embodiment, before testing, shows multiple touch area first on the touchscreen.Touch area can be tester pre-set and store, direct region of calling display from storage unit in use, also can be that tester carried out setting and the region shown before each test.The number of touch area and position can adjust according to test requests such as measuring accuracies, but preferred multiple setting touch areas scattering device is in the whole touch area of touch-screen, to expand test specification, to improve measuring accuracy.Such as, as shown in Figure 3, can mark five border circular areas 31 to 35 on the touch screen 3 as touch area, the radius of border circular areas can rationally be arranged as required, and each border circular areas correspond to a touch point on touch-screen.Such as, set an area threshold, require that the area of each border circular areas is greater than this area threshold, then can calculate a radius threshold according to area threshold, the radius then arranging each border circular areas is greater than this radius threshold.
In this embodiment, touch area is not limited to rounded face region shown in Fig. 3, that have certain area, can also be the region, face of other shapes, as elliptical region etc.Or, also can also be a region.But preferably there is certain area, the border circular areas of regular shape and elliptical region, like this, be convenient in error allowed band, judge whether touch point there occurs movement easily, judge that convenience, process are simple, be beneficial to the raising of testing efficiency, specifically can with reference to below to the description of Fig. 2 embodiment.
Step 103: when test starts, pin the touch area on touch-screen.
Here, according to test needs, part or all of touch area can be selected as the region of test.Such as, for five touch areas illustrated in fig. 3, wherein four are only selected to use.When test starts, pin these four touch areas on touch-screen successively or simultaneously with four fingers or electrostatic pen, each touch area will correspond to a touch point.
Step 104: judge whether correctly to pin required touch area.If so, 106 are gone to step; If not, step 105 is performed.
Because this embodiment is when judging test result, need to obtain actual touch area, for ensureing the accuracy of test, reducing the misoperation because accurately not pinning touch area and the test error that causes, needing first to judge whether correctly to have pinned required touch area.The color of touch area can be utilized determine whether and correctly pin touch area, such as, adopt following determination methods: if the color of the touch area pinned becomes the second color from the first color, simultaneously with the 3rd color display touch point, as, the color of touch area becomes green from blueness, simultaneously with red display touch point, then judges correctly to have pinned touch area; Otherwise, think and correctly do not pin touch area.
Step 105: if correctly do not pin required touch area, if continue test, test result will produce error because of this misoperation.Therefore, this test operation mistake is judged.Then, 113 are gone to step.
Step 106: after correctly pinning required touch area, obtains touch area setting number.
Whether there is " ghost refers to " fault for detecting touch-screen, mainly having judged according to the number of the touch area pinned.Therefore, the number obtaining the original touch region pinned when test starts first is needed.In this embodiment, that correctly pin when original touch areal is test beginning, needed for test touch area number is also four of setting in step 103.Specifically, after correctly pinning required touch area, just can be detected the number of the touch area pinned by the touch point detecting unit in touch-screen, and using this number as setting number.
If selected all touch areas are required touch area, as needed all five touch areas in Fig. 3, in this case, the touch area setting number pinned is identical with the number of touch area.Therefore, if adopt the mode of this whole selection, then direct using shown go out touch area number as touch area setting number use, detect without the need to recycling touch point detecting unit, thus simplify testing procedure, be beneficial to the raising of testing efficiency.
Step 107: after correctly pinning required touch area and obtain touch area setting number, the timing time according to presetting starts timing.
Timing time can regulate according to the testing requirement of measuring accuracy and production line, such as, is chosen as 5 seconds.
Step 108: judge whether timing time arrives.If arrive, perform step 109; If do not arrive, then go to step 107 continuation timing and wait for.
It should be noted that in this timing course, need to pin corresponding touch point always.
Step 109: when timing time arrives, detects the number of the actual touch area pinned on touch-screen as actual number, then actual number and setting number is compared.
Step 110: judge whether actual number is greater than setting number.If so, step 111 is performed; If not, step 112 is performed.
Step 111: if the number in actual touch region is greater than setting number, judge that touch-screen breaks down, and this fault is " ghost refers to " fault, and exports result of determination.Then, step 113 is performed., also namely when pressing the n on touch-screen (setting number) touch area, the touch area more than n (actual number) can be there is on screen in so-called " ghost refers to " fault.
Step 112: if the number in actual touch region is not more than setting number, then judge that touch-screen is normal, and export the normal result of determination of touch-screen.Then, step 113 is performed.
Step 113: this step is transferred by above-mentioned steps 105, step 111 and step 112, namely when judging test operation mistake or being completed, exits this test process.
Step 114: flow process terminates.
The method of testing that this embodiment provides demonstrates multiple touch area on the touchscreen, the touch area demonstrated is utilized to carry out accurately, easily and quickly touching, and touch-screen can be had whether occurred " ghost refers to " fault by automatic decision, error in judgement rate is low, detection efficiency is high, and the large scale touch screen be particularly useful on production line detects.
Please refer to Fig. 2, this Fig. 2 shows the process flow diagram of inventive touch screen method of testing second embodiment.
As shown in Figure 2, the method flow of this embodiment test touch screen is as follows:
Step 201: flow process starts.
Step 202: show multiple touch area on the touchscreen.
The setting principle of touch area and requirement can with reference to described in figure 1 embodiments.Such as, still as shown in Figure 3, can mark five border circular areas 31 to 35 on the touch screen 3, the area of these five border circular areas is all greater than setting area threshold, and each border circular areas correspond to a touch point on touch-screen.
Step 203: when test starts, pin the whole touch areas on touch-screen.
For the touch area of five shown in Fig. 3, when test starts, pin this five touch areas successively or simultaneously with five fingers or electrostatic pen.
Step 204: judge whether correctly to pin required touch area.If so, step 205 is performed; If not, 215 are gone to step.
Because this embodiment is when judging test result, need to obtain actual touch area, for ensureing the accuracy of test, reducing the misoperation because accurately not pinning touch area and the test error that causes, needing first to judge whether correctly to have pinned required touch area.The color of touch area can be utilized determine whether and correctly pin touch area, such as, adopt following determination methods: if the color of the touch area pinned becomes the second color from the first color, simultaneously with the 3rd color display touch point, as, the color of touch area becomes green from blueness, simultaneously with red display touch point, then judges correctly to have pinned touch area; Otherwise, think and correctly do not pin touch area.
Step 205: after correctly pinning required touch area, using the touch area number demonstrated as setting number.
In this embodiment, owing to being pinned as required touch area all touch areas, in this case, setting number in touch area is identical with the number of the touch area demonstrated.Therefore, then the direct number that the number of the touch area demonstrated set as touch area uses.
Step 206: after correctly pinning required touch area, obtaining touch area setting number, the timing time according to presetting starts timing.
Timing time can regulate according to the testing requirement of measuring accuracy and production line, such as, is chosen as 5 seconds.
Step 207: the coordinate detecting the touch point at the touch area place pinned in real time.
For ensure test accuracy, reduce artificial mobile touch point and the test error that causes, this embodiment needs the coordinate of the touch point detecting the touch area place pinned in real time in test process.
Step 208: judge whether to exist the touch point be positioned at outside touch area.If exist, go to step 215; If do not exist, perform step 209.
Following method can being adopted to judge whether to exist the touch point be positioned at outside touch area: for the region, face with certain area, just can obtain the coordinate of each point in touch area when showing touch area.In the coordinate system identical with the point in touch area, detect the coordinate of touch point on touch-screen, the touch point coordinate of detection and the coordinate of touch area mid point are compared, can judge whether the coordinate of touch point drops on outside touch area.And for point coordinate, then can directly the touch point coordinate of detection and point coordinate be compared, if both are different, then think that touch point is positioned at outside touch area.Due to touch-screen arrange time, its touch location is generally be effective touch in certain area, and therefore, this embodiment preferably adopts region, face as touch area, so that judge within the scope of permissible error whether touch point there occurs movement easily.
The object arranging this step is on the one hand avoid touch point in test process to affect the judgement of test result because manual operation is moved, and is can the drifting fault that exists of Timeliness coverage touch-screen on the other hand.
Step 209: when there is not the touch point be positioned at outside touch area, judges whether the color of the touch area pinned changes.If change, go to step 215; If do not change, perform step 210.
In test process, if the touch area pinned by people for unclamping, will affect the judgement of test result, this belongs to manual operation mistake, and might not be that touch-screen there occurs fault.The test error caused in order to avoid this kind of manual operation mistake, this embodiment detects the color of the touch area pinned in real time in test process.If color there occurs change, such as, when normally pinning, touch area is for green, if color has become blueness or red, has then thought touch area by people for unclamping, and performs different processing procedures according to judged result.
Step 210: judge whether timing time arrives.If arrive, perform step 211; If do not arrive, go to step 206, continue in timing waiting process, judge the position of the touch point in touch area and the color of touch area.
Step 211: when timing time arrives, detects the actual touch area number pinned on touch-screen and, as actual number, then actual number and setting number is compared.
Step 212: judge whether actual number is greater than setting number.If so, step 213 is performed; If not, step 214 is performed.
If step 213: the number of the touch area pinned actual is greater than setting number, judges that " ghost refers to " fault appears in touch-screen, also namely after pressing on touch-screen five touch areas, certain time, screen has occurred the touch area more than five.After output result of determination, perform step 216.
Step 214: if the number in actual touch region is not more than setting number, then judge that touch-screen is normal, and export the normal result of determination of touch-screen.Then, step 216 is performed.
Step 215: this step transfers according to the judged result of above-mentioned steps 204, step 208 and step 209, if namely correctly do not pin required touch area or the touch point be positioned at outside touch area or the color of touch area pinned there occurs change, then discriminating test operating mistake yet.Then, step 216 is performed.
Step 216: this step is transferred by above-mentioned steps 213, step 214 and step 215, namely when judging test operation mistake or being completed, exits this test process.
Step 217: judge whether exit number of times reaches 3 times.If so, step 218 is performed; If not, go to step 203, again perform test process.
Because the human operational error in operating process is inevitable, this embodiment allows multiple exercise test process to reduce the impact of human error.In order to improve testing efficiency, reduce fault loss, the number of times repeating test will limit, because if same mistake repeatedly occurs, such as repeatedly occur that in test process, touch point is positioned at the phenomenon outside touch area, then because human operational error causes, very likely may not really occur that drifting fault causes just because of touch-screen.Therefore, this embodiment provides for the number of times repeating test is 3 times, and such number of times arranges and can either give tester the chance of fully correcting a mistake operation, turn avoid the low of the testing efficiency frequently repeating to cause.
Step 218: if exit number of times to reach 3 times, then judge that touch-screen breaks down, and export result of determination.
Step 219: flow process terminates.
In this embodiment, if cause having repeated three tests because touch point is positioned at the reason outside touch area, and still there are the words of this problem, then can get rid of the operating mistake of artificial mobile touch point, and judge that " drift " fault has appearred in touch-screen, the touch location on the touch-screen also namely identified and actual touch position inconsistent and cause touch-screen respond mistake fault.So, utilize the method for testing of this embodiment, can not only detect that touch-screen breaks down, and can detect whether there occurs " ghost refers to " fault or " drift " fault, improve automaticity and the testing precision of testing touch screen.
