Detailed description of the invention
Fig. 1 is a kind of coordinate combination detection method of touch screen flow chart that embodiment 1 proposes；
Fig. 2 is a kind of coordinate combination detection method of touch screen flow chart that embodiment 2 proposes.
Specific embodiment
Referring to Fig.1, a kind of coordinate combination detection method of touch screen proposed by the present invention, comprising the following steps:
S1, reference axis is established according to touch screen.
Multiple and different point on S2, pressing touch screen, and record coordinate of each press points in reference axis and sit as a comparison
Mark.
During S3, pressing, the output signal that touch screen is generated according to push action is obtained, and according to the output of touch screen
Signal reversely calculates and the one-to-one reference coordinates of each pressing position in reference axis.
Touch screen generates touch signal by touch panel, and touch screen inside or external processor pass through identification touching
Touch signal and reverse-direction derivation operational order.So touch screen guarantees touch signal and touches dynamic as a kind of human-computer interaction tool
The correct mapping made, is a kind of very important index of quality.
S4, reduced coordinates is compared with reference coordinates, and judges whether touch screen is qualified according to comparison result.Specifically
, this step S4 is specifically, judge whether reduced coordinates corresponds with reference coordinates, and corresponding reduced coordinates and reference
Coordinate is overlapped.It is then to judge touch screen qualification.It is no, then judge that touch screen is unqualified.
In this way, in present embodiment, and by according to touch screen signal the touch action of reverse-direction derivation with directly acquire
Touch action compare the quality to judge touch screen, design is rationally and directly effectively.Meanwhile in present embodiment, lead to
Setting reference axis is crossed, coordinate is carried out to the touch action directly acquired and the touch action reversely shifted onto and is embodied, touching is facilitated
Movement and the comparison for the touch action reversely shifted onto judgement are touched, so that the standard for realizing touch screen detection is embodied, is conducive to
Improve the accuracy of touch screen detection.
S5, when touch screen it is unqualified, then record the reference that does not correspond to and be overlapped in touch screen number and the touch screen
The reduced coordinates of coordinate.Its press points compared not over detection is recorded for underproof touch screen in this way, being equivalent to,
To facilitating subsequent quick acquisition touch screen abnormal area, done over again overhaul efficiency with improving touch screen.
Embodiment 1
In the present embodiment, step S2 specifically: multiple and different point on pressing touch screen, by camera to pressing process
It is monitored and acquires image, then the coordinate as a comparison of the coordinate according to each press points of image zooming-out in reference axis.
In this way, in the present embodiment, reduced coordinates is directly acquired by image analysis, intelligence degree is high, operation require it is low,
Advantageously reduce fault rate.
Embodiment 2
In the present embodiment, step S2 specifically includes the following steps:
S21, setting template, and pressing structure is preset on touch tablet, and establish in a coordinate system according to pressing structure
Multiple reduced coordinates.
S22, touch screen is mounted relative to the static position of template and fixation, passes through the pressing structure on touch tablet
Multiple spot pressing is carried out on the touchscreen, and press points and reduced coordinates correspond.
Specifically, in step S21, pressing structure is made of multiple through-holes, step S22 specifically: will be touched in the present embodiment
It touches screen to be mounted on immediately below mounting plate, and multiple spot pressing is carried out to touch screen by multiple through-holes.In this way, unified not by through-hole
With the press points of touch screen, the detection process of touch screen is unified, has been conducive to improve detection efficiency.
Alternatively, in step S21, pressing structure is made of multiple telescopic rods towards touch screen, step in the present embodiment
S22 specifically: by driving telescopic rod to extend in progress multiple spot pressing on touch screen.In this way, stretching into one by telescopic rod
Step improves the intelligent automaticization degree of the detection method.
