Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
The present invention detects the method for capacitance type touch control screen and has utilized a circuit board 1, and its concrete structure please refer to shown in Figure 1, is rectangular a series of electrodes 10 that are distributed with on the described circuit board 1, and each electrode 10 independently exists, and independently controls by control module.Owing to can set each small electrode 10 in advance and independently control, so in theory by of the variation of a series of program with regard to level on this circuit board of may command by each control module.
Because described circuit board 1 is made up of several small electrodes 10, and each small electrode 10 is independently controlled by each control module, so by setting the size of specific program, to reach the purpose that improves constantly the product test precision with regard to one group of electrode on the may command circuit board.During test, touch-screen (not indicating) is placed on the top of this circuit board 1, perhaps also circuit board can be positioned over touch-screen top, control electrode group's level changes then, reach and adjust the purpose that inductance capacitance changes on the touch screen, so just realized the mode of operation of emulation user finger touches touch screen.Following mask body is discussed its method of testing:
Please refer to shown in Figure 2ly, at first select one group of electrode such as electrode group 100 on the circuit board 1, the number of each electrode in its electrode group can be made up of any natural number.For the variation of level on the accurate control circuit board 1, we should not select excessive number; Simultaneously, in order to guarantee the variation of level on the quick control circuit board 1, we also should not select too small number.So variation of level on the accurate control circuit board 1 in order to satisfy simultaneously fast, the electrode group 100 that our selection is made up of nine small electrodes, by above-mentioned argumentation as can be known, utilize control module the level of electrode group 100 can be arranged to the level identical with the earth, promptly be connected with the earth; Perhaps make the zone of electrode group 100 connect some particular level, and the zone except that electrode group 100 on this circuit board 1, the level of promptly removing electrode group 100 outer All Rangeses can be set to other default level.The zone at electrode group 100 places just is equivalent to and has a finger like this, when this circuit board with electrode group 100 and touch-screen near the time, and with required electrode winding, just produced inductance capacitance between this electrode group and the touch screen electrode.Thus, we just can arrive the purpose that changes the inductance capacitance on the touch screen by the level of controlling this electrode group 100.At this moment, the coordinate that touch-screen is read and the equivalent coordinate in electrode group 100 zones contrast, and promptly whether the described touch screen of decidable exists unusually.
Above-mentioned method for detecting just singly refers to touch the situation of touch screen at emulation, singly refer to the detecting of slide mode on touch screen for emulation, please refer to shown in Figure 3, singly refer to the mode on touch screen, handled if will detect emulation, need to realize earlier the effect that electrode group 100 is slided on touch screen.Need utilize each control module to come moving of control electrode group 100 equally, on circuit board, slide to be used for controlling described electrode group.Because the level in electrode group 100 zones is connected with the level of the earth,, thereby realize that emulation points the mode of operation of sliding on touch screen so control module can be controlled and wait moving of ground electrode group 100 continuously.At this moment, Grid Track and the back Grid Track that is detected of electrode group 100 zone slips that touch-screen is read contrast, and whether the described touch screen of final decision exists unusually.
Above-mentioned detecting mode is utilized the mobile operation that has realized that the emulation finger moves on touch screen of the electrode group 100 on the circuit board 1, but only realized the motion that imitation singly refers to, method for detecting for many finger touches of emulation touch screen does not also relate to, and continues to discuss many fingers of emulation as two implementation methods that refer on circuit board 1 below again.
Situation for emulation two finger touches Trackpads, identical with the principle that singly refers to touch Trackpad, we need set the electrode group equally, but different is, need set two arrays of electrodes 100 and 101 in advance, please refer to shown in Figure 4, still utilize the level identical of being arranged to of control module with the earth with this two arrays of electrodes 100 and 101 region level, promptly be connected with the earth, perhaps make the zone of electrode group 100 and 101 connect some particular level, and the zone outside on this circuit board 1, the level of promptly removing the All Ranges outside two electrode groups 100 and 101 all is set to other default level.The zone at such two electrode groups 100 and 101 places just is equivalent to and has two fingers, when this circuit board 1 with two electrode groups 100 and 101 during near touch screen, will produce corresponding inductance capacitance, has reached the operation of emulation two finger touches touch screens.Thus, we just can arrive the purpose that changes the inductance capacitance on the touch screen by the level of controlling this two electrodes group 100 and 101.At this moment, the coordinate that touch-screen is read and the coordinate of two electrode groups 100 and 101 corresponding regions contrast, and promptly whether the described touch screen of decidable exists unusually.
For the variation of each level on the more accurate control circuit board 1, above-mentioned each related electrode 10 also can be designed to other different shape, as circle, and ellipse etc.Equally, the electrode group of being made up of electrode 10 100 or 101 also can change different shapes as required.For emulation greater than two operations of finger on touch screen, it also is same reason, promptly by controlling different electrode groups and it being connected with the earth, guaranteeing that its level is identical with the earth has realized that emulation refers to touch the operation of touch screen more, finally the coordinate of reading by touch-screen is compared with the equivalent coordinate of counter electrode group region, to judge whether touch screen exists unusually.
The method of detecting touch screen of the present invention utilizes static mode to realize that dynamic simulation refers to touch screen effect more, and not only method is easy, and saves time and expense.It is more convenient to use.
