Abstract
The invention relates to the field of detection device for flat display screen, and especially relates to a lighting device for the automatic optical detection on flat display screen. The lighting device comprises a back light source, which is arranged on the bottom of a display screen to be detected; side light sources, which are arranged on two sides of the display screen to be detected; and a bearing mechanism, which is used to support the back light source and the side light sources. The lighting device can satisfy the requirements on image brightness variation and uniformity of display screen after the display screen is lighted up, and at the same time can lighten the dusts. The dusts can be effectively removed through a detection algorithm so as to recognize the electrical test performance defects of a display screen.
Description
Technical field
The present invention is applied to flat panel display screen detection device field, particularly a kind of polisher that is applied to the detection of panel display screen automated optical.
Background technology
Panel display screen automated optical detection equipment, the TFT-LCD(Thin Film Transistor Liquid Crystal Display for flat pannel display industry, Thin Film Transistor (TFT)-liquid crystal display), AM-OLED(Active Matrix/Organic Light Emitting Diode, active-matrix organic light emitting diode (AMOLED) panel) equipment that detects of screen quality.This equipment can detection display electrical measurement performance and intrinsic defect itself of screen, such as stain, white point, concealed wire, bright line, Mu La (mura) etc.
In prior art, conventionally adopt a backlight to carry out polishing to the screen of lighting, human eye is identified product defects.In actual testing process, because testing environment exists light-source brightness poor, the problem such as evenly effect is bad, adjustable extent is little, has a strong impact on vision system for the processing of properties of product.On the surface of display screen, mostly easily pile up some dusts simultaneously.For effective differentiation of dust and foreign matter, it is also a great problem.
Summary of the invention
(1) technical matters that will solve
The technical problem to be solved in the present invention is to provide a kind of polisher that panel display screen automated optical detects that is applied to, and to overcome, polisher light-source brightness of the prior art is poor, the little detection level causing of adjustable extent is limited and the problem of difficult difference electrical measurement defect and dust.
(2) technical scheme
In order to solve the problems of the technologies described above, the polisher that is applied to the detection of panel display screen automated optical provided by the invention, comprising:
Backlight, described backlight is positioned at the bottom of display screen to be measured;
Side light source, described side light source is positioned at the both sides of display screen to be measured;
Load carrier, described load carrier is used for carrying backlight and side light source.
Further, described side light source is installed on the both sides of display screen to be measured by runing rest.
Further, described side light source is LED strip light.
Further, described backlight is that intensity is adjustable, the uniform light source of light.
Further, also comprise algorithm process system, described algorithm process system is irradiated determinand image by processing side light source, analyzes the character that is present in the particle on display screen to be measured.
(3) beneficial effect
The polisher that is applied to the detection of panel display screen automated optical that the embodiment of the present invention provides, can meet display screen to be measured and light rear display image brightness variation and inhomogeneity requirement, can meet again the object of beating bright dust.By the effective filtering dust of detection algorithm, identification display screen electrical measurement performance deficiency.
Accompanying drawing explanation
Fig. 1 is that the embodiment of the present invention is applied to the polisher structural representation that panel display screen automated optical detects.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, the polisher that is applied to the detection of panel display screen automated optical that the embodiment of the present invention provides, comprising: backlight 1, side light source 2, side light source 3 and load carrier 4.
The polisher that is applied to the detection of panel display screen automated optical that the embodiment of the present invention provides, can meet display screen to be measured and light rear display image brightness variation and inhomogeneity requirement, can meet again the object of beating bright dust.By the effective filtering dust of detection algorithm, identification display screen electrical measurement performance deficiency.
Wherein, this backlight 1 is positioned at the bottom of display screen to be measured, and its light sending is radiated at the bottom of display screen equably, when display screen to be measured has signal, for detecting operation, provides lighting condition.Wherein, this backlight is that intensity is adjustable, the uniform light source of light.
Side light source 2, side light source 3 are positioned at the both sides of display screen to be measured, it is installed on the both sides of display screen to be measured by runing rest, this runing rest can be rotated this side light source, its light sending is radiated at the surface of display screen to be measured uniformly, for the detection to display screen surface foreign matter to be measured.This bilateral side light source can be to display screen to be measured Superficial Foreign Body polishing, thereby foreign matter highlight surface.By to display screen surface foreign matter to be measured imaging, algorithm process system is abnormal in display screen to the particle on this display screen to be measured of graphical analysis gathering, or display screen surface foreign matter.
Concrete, this side light source can be LED strip light.
Load carrier 4 is for carrying backlight 1 and side light source, and this backlight 1 and side light source are installed on load carrier 4, and load carrier, can also be for carrying camera, camera lens 5, display screen to be measured etc. except installing above-mentioned parts.
Panel display screen to be measured in the present embodiment is the panel display screens such as TFT-LCD, AM-OLED.
The polisher that is applied to the detection of panel display screen automated optical that the embodiment of the present invention provides, can meet display screen to be measured and light rear display image brightness variation and inhomogeneity requirement, can meet again the object of beating bright dust.By the effective filtering dust of detection algorithm, identification display screen electrical measurement performance deficiency.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
