Abstract
The invention discloses a kind of display screen foreign matter detecting method, comprise the following steps：(1) display screen is fixed；(2) electric current of the electrode outflow of detection touch-screen, and the coordinate value converted electrical current on touch-screen；(3) full frame extruding is carried out to display screen, obtains the coordinate value on touch-screen, detect the pressure at effective coordinate value of the display screen；(4) judge whether the above-mentioned pressure measured is less than a default threshold value, and regard effective coordinate value that pressure is less than the threshold value as foreign matter coordinate value；(5) judged to whether there is foreign matter in display screen according to display screen pressing image and foreign matter coordinate value.
Description
Technical field
The present invention relates to display screen technology field, and in particular to a kind of display screen foreign matter detecting method.
Background technology
With the development of electronic imaging technology, it is each that display screen is widely applied to each row as a kind of picture and text showing instrument
Industry.In display screen production process, it is difficult to avoid occurring foreign matter inside it.And gently then influenceed inside display screen once there is foreign matter
Graphic display screen definition and accurate, severe one influence display screen service life.So, it is internal different in display screen production process
Analyte detection is essential quality inspection procedure.
The content of the invention
The present invention is intended to provide a kind of display screen foreign matter detecting method.
The present invention provides following technical scheme：
A kind of display screen foreign matter detecting method, comprises the following steps：
(1) display screen is fixed；
(2) electric current of the electrode outflow of detection touch-screen, and the coordinate value converted electrical current on touch-screen；
(3) full frame extruding is carried out to display screen, obtains the coordinate value on touch-screen, detect effective coordinate value of the display screen
The pressure at place；
(4) judge whether the above-mentioned pressure measured is less than a default threshold value, and effective seat by pressure less than the threshold value
Scale value is used as foreign matter coordinate value；
(5) judged to whether there is foreign matter in display screen according to display screen pressing image and foreign matter coordinate value.
The display screen pressing image includes display screen pressing front side image and display screen pressing rear image belongs to show
Display screen pressing image.
The coordinate value is obtained by the detection of coordinate value acquisition module, and coordinate value acquisition module is used for the electricity for detecting touch-screen
The electric current of pole outflow and the coordinate value converted electrical current on touch-screen.
The effective coordinate carried out to display screen after full frame extruding by pressure detecting module for detecting the touch-screen
Pressure at value.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention judges display screen according to display screen pressing image
Inside whether there is foreign matter, i.e., judged according to general image, the real-time judge being pressurized relative to display screen single-point, improve
The efficiency of display screen foreign bodies detection, the present invention can to display screen carry out automatically extrude in a balanced way, and to display screen inside whether
There is foreign matter and carry out intellectual determination, can detecting and whether there is foreign matter on display screen, being capable of detecting when when there is foreign matter different
Position where thing, and inform that user is timely cleared up, so as to avoid display screen part caused by the presence of foreign matter
Area failures and influence Consumer's Experience, the automation and intelligentification detection demand of display screen can be achieved to manually relying on low in the present invention.
