Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In the field of display technology, flat panel display technology has been increasingly used for cathode ray tube displays. In the process of manufacturing flat panel display, the backlight source of the display panel or the brightness of the panel surface affects the detection result of the detection personnel, so that the gray value needs to be controlled. Taking an LCD display panel as an example, a inspector needs to spot-inspect the luminance values of the panel, and holds the luminance meter by the inspector, if the display panel is divided into nine areas arranged in an array, the inspector needs to sequentially measure the luminance values of the nine areas, which consumes manpower and is complex to operate. The detection personnel detect that each display panel needs to stop for 20 minutes in a manual mode to carry out spot detection, and if abnormal operation occurs to the detection personnel in the detection process, the stop time of the production line in the spot detection process can reach more than 1 hour, and the production efficiency of the production line is seriously affected.
In order to improve the detection efficiency of the display panel, the embodiment of the application provides a fault detection system. The fault detection system may be applied to a display panel, specifically, may be an LCD display panel or an OLED display panel in a flat panel display technology, and may also be applied to fault detection of other electronic devices, such as an electronic device that needs area detection, which is not limited herein. Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the disclosure. The display panel 100 may include a plurality of to-be-detected areas 110, and if the display panel 100 is in a regular pattern such as a rectangle or a square, the plurality of to-be-detected areas 110 are arranged in an array on the display panel 100; if the display panel 100 is circular or elliptical, the display panel 100 may be divided into a plurality of to-be-detected areas 110 according to an horizontal-vertical arrangement, and the specific arrangement manner of the plurality of to-be-detected areas 110 is not particularly limited herein.
Referring to fig. 2 and 3, fig. 2 is a first structural schematic diagram of a fault detection system according to an embodiment of the present application, and fig. 3 is a second structural schematic diagram of a fault detection system according to an embodiment of the present application. The fault detection system 200 may include a detection device 210, a driving device 220, and a processor 230, where the processor 230 is electrically connected to the detection device 210 and the driving device 220, respectively.
The detection device 210 may be a sensor module, and may include a plurality of spot detection modules 211, where each spot detection module 211 may have a function of detecting luminance, and the luminance indicates an intensity of light emitted from the surface of the display panel, or may be brightness, that is, each spot detection module 211 may correspondingly detect a luminance value in the display panel 100, and the spot detection module 211 may be a luminance meter or the like. Since the detection range of each spot detection module 211 for detecting the luminance value of the display panel is limited, in order to improve the detection accuracy, each spot detection module 211 may correspond to one to-be-detected area 110, and the detection range of each spot detection module 211 needs to be greater than or equal to the coverage area of one to-be-detected area 110, so that the luminance values of the to-be-detected areas 110 may be detected by the plurality of spot detection modules 211 to detect a plurality of luminance data corresponding to the to-be-detected areas 110.
The driving device 220 may drive the detecting device 210 to move, specifically, drive the plurality of spot inspection modules 211 in the detecting device 210 to move to positions corresponding to the plurality of areas to be detected 110. The driving device 220 may be a motor, or may include a driving motor and a gear set, where the driving motor may be meshed with the gear set, and the gear set may be driven by the driving motor to rotate to drive the detecting device 210 to move. The driving device 220 is not limited to this.
In the process of performing fault detection by the fault detection system 200, the processor 230 may control the driving device 220 to drive the plurality of spot detection modules 211 to move to positions corresponding to the plurality of areas to be detected 110, thereby acquiring a plurality of luminance data corresponding to the plurality of areas to be detected 110 detected by the plurality of spot detection modules 211 in the detecting device 210, comparing the plurality of luminance data with the stored normal luminance data after the plurality of luminance data are acquired, thereby determining whether abnormal luminance data exist in the plurality of luminance data, if so, taking the area to be detected 110 corresponding to the abnormal luminance data as a target fault area, thereby detecting the position where the display panel 100 fails, and if not, indicating that the display panel has no abnormality in the spot detection process, and then entering the next step of the production line. Through the fault detection system 200, automatic spot inspection of the display panels can be realized, and the downtime of each display panel in the spot inspection process can be reduced to be less than 1 minute, so that the influence on the production of a production line is reduced by improving the detection efficiency, and the productivity is improved.
With continued reference to fig. 3, the fault detection system 200 may further include a main body 240, a shaft 250, and a connection structure 260.
The main body 240 may serve as a carrier for the rotating shaft 250 and the connection structure 260, or may serve as a carrier for the detecting device 210 and the driving device 220, and may be referred to as a housing or a casing. The body 240 may be formed of plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), other lotus-based materials, or a combination of any two or more of these materials. The metal is aluminum alloy, magnesium aluminum alloy, stainless steel, etc.
The body 240 may be regular in shape, and in some embodiments, the body 240 may be a cylindrical structure, or a tubular structure, such as a cylindrical structure, a frustoconical structure, a conical structure, a polyhedral structure, or the like. I.e., the body 240 forms a circular or polygonal shape in a sectional view in a radial direction thereof. The main body 240 may have an irregular shape.
The display panel 100 may have a rectangular shape with four sides, i.e., upper, lower, left and right sides, connected to each other. The main body 240 may be disposed at an upper side of the display panel 100, but may be disposed at other sides. The body 240 includes at least one end portion and at least one side portion. For example, the body 240 may have a first end 241, a second end 242, and a first side 243. Wherein the first end 241 and the second end 242 may be disposed opposite to each other, the first end 241 and the second end 242 may be disposed at opposite ends of the main body 240, and the first end 241 and the second end 242 may be connected by a first side 243, or the first side 243 may be connected between the first end 241 and the second end 242.
The radial direction of the main body 240 is a direction surrounding the first side 243, the axial direction of the main body 240 is a direction in which the first end 241 faces the second end 242, or the axial direction of the main body 240 is a direction in which the second end 242 faces the first end 241. The axial direction and the radial direction of the body 240 are perpendicular to each other.
The first end 241, the second end 242, and the first side 243 form a receiving cavity on the body 240 that can receive components of the fault detection system 200, such as the receiving cavity that can receive the detection device 210, the drive device 220, etc. of the fault detection system 200.
The first end 241 and the second end 242 may or may not be disposed in parallel. The dimensions of the first end portion 241 and the second end portion 242 may be the same or different.
The first side 243 may be a cylindrical, conical structure, and the first side 243 may also have at least two interconnected faces. When the first side portion 243 has two interconnected faces, the first side portion 243 may include at least one arcuate face, such as where the side first side portion 243 includes one arcuate face and one planar face, and such as where the first side portion 243 includes two arcuate faces. When the first side portion 243 has at least three surfaces connected to each other, all surfaces of the first side portion 243 may be arcuate surfaces, all surfaces of the first side portion 243 may be planar, and the surfaces of the first side portion 243 may be formed by connecting at least one arcuate surface and at least one planar surface.
The first side 243 of the main body 240 is provided with a first through hole 244. The first through hole 244 may penetrate the first side 243. The first through hole 244 may be in a bar shape, and the first through hole 244 may be formed between the first end portion 241 and the second end portion 242, and the extending direction of the first through hole 244 may be the same as the upper direction of the display panel 100, and if the display area of the display panel 100 is divided into rows and columns, the extending direction of the first through hole 244 is the same as the row direction of the display panel 100. The first through hole 244 may be used for the components of the fault detection system 200, such as the detection device 210 and the connection structure 260, to extend from within the body 240 to outside of the body or to be received within the body.
The rotating shaft 250 may be disposed in the main body 240, the rotating shaft 250 may be electrically connected to the driving device 220, and the driving device 220 may drive the rotating shaft 250 to rotate in the main body 240. The rotating shaft 250 may have a hollow structure, and the driving device 220, the battery, etc. may be disposed at a hollow position of the rotating shaft 250. The shaft 250 may rotate not only with respect to the body 240, but also with respect to components within the fault detection system 200.
Rotation of the shaft 250 may rotate the connection structure 260. For example, one end of the connection structure 260 may be fixed to the rotation shaft 250, the connection structure 260 may be wound around the rotation shaft 250, and the connection structure 260 may be gradually received in the body 240 during the winding of the connection structure 260 around the rotation shaft 250. Such as: the rotation shaft 250 rotates in the second direction, and the connection structure 260 may be wound around the rotation shaft 250 to receive the connection structure 260 in the main body 240. I.e., the connection structure 260 is wound or stretched according to the rotation of the rotation shaft 250.
Specifically, the connection structure 260 may be received in the main body 240 through the first through hole 244 or protrude from the inside of the main body 240 to the outside of the main body 240. One end of the connection structure 260 positioned at the position of the body 240 or the first through hole 244 may rotate the rotation shaft 250 to extend the connection structure 260 received in the body 240 to the extended extension of the body 240. It should be noted that, the driving device 220 may be controlled by the processor 230 to automatically control the rotation of the rotation shaft 250, so that the connection structure 260 is housed in the main body 240 or extends out of the main body 240 from the main body 240 following the rotation of the rotation shaft 250.
With continued reference to fig. 3, the connection structure 260 may include a plurality of first connectors 261 and a plurality of second connectors 262, where one first connector 261 may be connected with one spot inspection module 211, and the plurality of first connectors 261 in the same row may be sequentially connected, so that the plurality of spot inspection modules 211 in the same row are arranged at intervals. Since the first connectors 261 in the same row are sequentially connected, if the same row includes three first connectors 261, there are four second connectors 262 in the row to ensure that two sides of one first connector 261 are connected with one second connector 262.
Wherein the plurality of first coupling members 261 and the plurality of second coupling members 262 may be flexible structures so as to be capable of being wound around the rotation shaft 250 when the coupling structure 260 is contracted within the main body 240. One end of the plurality of second connecting pieces 262 is detachably and fixedly connected with the rotating shaft 250, so that when the display area of the display panel is larger or smaller, the second connecting pieces 262 can be increased or reduced to be matched with the detection area of the display panel, the other end of the plurality of second connecting pieces 262 is detachably and fixedly connected with the plurality of first connecting pieces 261 in the same row, and when the first connecting pieces 261, the spot inspection module 211 or the second connecting pieces 262 have a circuit connection problem, the second connecting pieces 262 and the rotating shaft 250 or the second connecting pieces 262 and the first connecting pieces 261 can be detachably and fixedly connected, and maintenance or replacement can be completed.
In the process that the driving device 220 drives the plurality of spot inspection modules 211 in the detecting device 210 to move to the positions corresponding to the plurality of areas to be detected 110, it may be that the driving device 220 drives the rotating shaft 250 to rotate clockwise along the first direction, and the plurality of second connecting pieces 262 in the connecting structure 260 simultaneously rotate relative to the rotating shaft 250, so as to drive the plurality of first connecting pieces 261 interconnected with the plurality of second connecting pieces 262 to move, and further drive the plurality of spot inspection modules 211 interconnected with the plurality of first connecting pieces 261 to extend out of the main body 240 from the inside of the main body 240, so that the plurality of spot inspection modules 211 move to the positions corresponding to the plurality of areas to be detected 110, thereby realizing detection of the luminance values of the plurality of areas to be detected 110 through the plurality of spot inspection modules 211.
Correspondingly, after the plurality of spot inspection modules 211 complete fault detection on the plurality of areas to be detected 110, the processor 230 may further control the driving device 220 to drive the rotating shaft to rotate along the second direction, for example, anticlockwise, and drive the plurality of first connectors 261 and the plurality of spot inspection modules 211 to wind from outside the main body 240 to inside the main body 240 through the plurality of second connectors 262.
It should be noted that, in the process that the detection device 210 extends out of the main body 240 from the main body 240, if the display panel 100 is in a vertical placement state, the main body 240 may be disposed on the upper side of the display panel 100, and in the process that the rotating shaft 250 drives the connecting structure 260 to rotate, the connecting structure 260 may drive the plurality of spot inspection modules 211 to move to positions corresponding to the plurality of areas 110 to be detected by gravity. If the transmission cannot be realized by gravity, that is, the display panel is in a horizontal state or the main body 240 is disposed on the left side, the right side or the lower side of the display panel, a supporting member may be disposed in the main body 240, during the rotation process of the driving device 220 driving the rotating shaft 250, the connecting structure 260 may extend out of the main body 240 from the main body 240 together with the supporting member, and the supporting member may support the connecting structure 260, so as to ensure that the connecting structure 260 may move to a preset position, that is, the connecting structure 260 drives the plurality of spot inspection modules 211 to move to positions corresponding to the plurality of areas 110 to be detected, and the supporting manner of the specific supporting member is not limited herein.
It should be further noted that, the connection structure 260, such as the first connection member 261 and the second connection member 262, may be made of a conductive material, so that the luminance data of the to-be-detected area 110 acquired by the spot detection module 211 may be transmitted to the memory, so as to implement the processing of the luminance data by the processor 230.
In addition, since the plurality of to-be-detected areas 110 in the display panel 100 are arranged in an array, the plurality of to-be-detected areas are distributed in a plurality of rows, and the main body of the fault detection system 200 is disposed on the upper side of the display panel, if the number of the plurality of spot detection modules 211 in the detection device 210 is the same as the number of the plurality of to-be-detected areas, the processor 230 may control the driving device 220 to drive the rotating shaft 250 to rotate along the first direction, and the plurality of first connectors 261 and the plurality of spot detection modules 211 are driven by the plurality of second connectors 262 to extend out of the main body 240 from the inside of the main body 240, so that the plurality of spot detection modules 211 are in one-to-one correspondence with the plurality of to-be-detected areas 110, a plurality of luminance data of the plurality of to-be-detected areas 110 detected by the plurality of spot detection modules 211 are acquired, whether abnormal luminance data exist in the plurality of luminance data is determined, and if the abnormal luminance data exist, the to-be-detected areas 110 corresponding to the abnormal luminance data are regarded as the target fault areas.
The fault detection system 200 is configured to provide a plurality of spot detection modules 211 corresponding to the plurality of areas to be detected 110, so as to detect the fault of the display panel 100 at one time.
