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 is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the field of display technology, flat panel display technology has gradually taken the place of cathode ray tube displays. In the flat panel display manufacturing process, the brightness of the backlight source of the display panel or the panel surface affects the detection result of the detection personnel, so the gray value needs to be controlled. Taking the LCD display panel as an example, the detection personnel need to perform spot detection on the luminance value of the panel, and the detection personnel hold the luminance meter by hand, and if the display panel is divided into nine areas arranged in an array, the detection personnel need to measure the luminance values of the nine areas in sequence, which consumes manpower and is complex to operate. The manual mode of detection personnel detects that it needs to shut down 20 minutes to carry out the point to every display panel and examines, if detection personnel misoperation appears unusually in the testing process, then the time that the production line stops the line in the point process of examining will reach more than 1 hour, seriously influences production line production efficiency.
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, 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 electronic devices that require area detection, and the like, 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 present disclosure.

Referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of a fault detection system according to an embodiment of the present disclosure, and fig. 3 is a schematic structural diagram of a fault detection system according to an embodiment of the present disclosure. The fault detection system 200 may include a detection device 210, a driving device 220, and a processor 230, wherein the processor 230 is electrically connected to the detection device 210 and the driving device 220, respectively.
The detecting device 210 may be a sensor module, and may include a plurality of point detecting modules 211, each of the point detecting modules 211 may have a function of detecting luminance, where the luminance is an intensity of light emitted from a surface of the display panel, and may also be a luminance, that is, each of the point detecting modules 211 may detect a luminance value in the display panel 100, and the point detecting module 211 may be a luminance meter, etc. Because each point inspection module 211 has a detection range limitation for detecting the luminance value of the display panel, in order to improve the detection precision, each point inspection module 211 can correspond to one region 110 to be detected, and the detection range of each point inspection module 211 needs to be larger than or equal to the coverage area of one region 110 to be detected, so that luminance value detection can be performed on a plurality of regions 110 to be detected through a plurality of point inspection modules 211 to detect a plurality of luminance data corresponding to the plurality of regions 110 to be detected.
The driving device 220 may drive the detecting device 210 to move, and specifically, drive the plurality of spot inspection modules 211 in the detecting device 210 to move to positions corresponding to the plurality of regions 110 to be detected. The driving device 220 may be a motor or other devices, and may also include a driving motor and a gear set, where the driving motor may be engaged 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 regions to be detected 110, so as to obtain a plurality of luminance data corresponding to the plurality of regions to be detected 110 detected by the plurality of spot detection modules 211 in the detection device 210, after obtaining the plurality of luminance data, compare the plurality of luminance data with the stored normal luminance data, so as to determine whether there is abnormal luminance data in the plurality of luminance data, if so, the region to be detected 110 corresponding to the abnormal luminance data is taken as a target fault region, so as to detect a position where the display panel 100 has a fault, and if not, it indicates that the display panel has no abnormality in the spot detection process, and then the next step of the production line may be entered. Through this fault detection system 200 can realize the automatic point inspection to display panel, and the down time of each display panel in the point inspection in-process can reduce to within 1 minute to reduce the influence to producing the line production through promoting detection efficiency, promote the productivity.

That is, a cross-sectional view of the body 240 in a radial direction thereof forms a circle or a polygon. The main body 240 may have an irregular shape.
The display panel 100 may have a rectangular shape having four sides, i.e., an upper side, a lower side, a left side, and a right side, which are connected to each other. The main body 240 may be disposed on the upper side of the display panel 100, but may be disposed on other sides. The body 240 includes at least one end and at least one side. For example, the body 240 may have a first end 241, a second end 242, and a first side 243. The first end portion 241 and the second end portion 242 may be disposed opposite to each other, the first end portion 241 and the second end portion 242 may be disposed at opposite ends of the main body 240, and the first end portion 241 and the second end portion 242 may be connected by a first side portion 243, or the first side portion 243 may be connected between the first end portion 241 and the second end portion 242.
It should be noted that the radial direction of the main body 240 is a direction surrounding the first side portion 243, the axial direction of the main body 240 is a direction in which the first end portion 241 faces the second end portion 242, or the axial direction of the main body 240 is a direction in which the second end portion 242 faces the first end portion 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 main body 240, which can receive the components of the fault detection system 200, such as the detection device 210, the driving device 220, and the like of the fault detection system 200.
The first end portion 241 and the second end portion 242 may be disposed in parallel, or may not be disposed in parallel. The size of the first end 241 and the size of the second end 242 may be the same or different.
The first side portion 243 may have a cylindrical structure and a conical structure, and the first side portion 243 may also have at least two surfaces connected to each other. When the first side portion 243 has two surfaces connected to each other, the first side portion 243 may include at least one arc surface, for example, the first side portion 243 includes one arc surface and one flat surface, and for example, the first side portion 243 includes two arc surfaces. When the first side portion 243 has at least three surfaces connected to each other, all the surfaces of the first side portion 243 may be arc-shaped surfaces, all the surfaces of the first side portion 243 may also be flat surfaces, and the surfaces of the first side portion 243 may also be formed by connecting at least one arc-shaped surface and at least one flat surface.
The first side 243 of the body 240 is provided with a first through hole 244. The first through hole 244 may penetrate the first side portion 243. The first through hole 244 may have a bar shape, the first through hole 244 may be formed between the first end portion 241 and the second end portion 242, the extending direction of the first through hole 244 may be the same as the upper side 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 may be the same as the row direction of the display panel 100. The first through hole 244 may be used for devices of the fault detection system 200, such as the detection device 210 and the connection structure 260, to extend from within the main body 240 to outside the main body or to be received within the main 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, a 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 devices inside the fault detection system 200.
Rotation of the shaft 250 may cause the connection structure 260 to rotate. 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 is gradually received in the main body 240 during the process of winding the connection structure 260 around the rotation shaft 250. Such as: the rotating shaft 250 rotates in the second direction, and the connecting structure 260 may be wound on the rotating shaft 250 to receive the connecting structure 260 in the main body 240. That is, the connection structure 260 performs winding or extension according to the rotation of the rotation shaft 250.
Specifically, the connection structure 260 may be received within the main body 240 or protrude from within the main body 240 to the outside of the main body 240 through the first through hole 244. The connecting structure 260 can be positioned at one end of the main body 240 or the first through hole 244 to rotate the rotating shaft 250 so as to extend the connecting structure 260 received in the main body 240 to be spread outward. It should be noted that the processor 230 may control the driving device 220 to automatically control the rotation of the rotating shaft 250 so that the connecting structure 260 is received in the main body 240 or extends out of the main body 240 from the main body 240 along with the rotation of the rotating shaft 250.
Referring to fig. 3, the connection structure 260 may include a plurality of first connection members 261 and a plurality of second connection members 262, one first connection member 261 may be connected to one spot inspection module 211, and the plurality of first connection members 261 in the same row may be sequentially connected, so that the plurality of spot inspection modules 211 arranged at intervals in the same row are provided. Both sides of one first connecting piece 261 are respectively detachably and fixedly connected with one second connecting piece 262, and since a plurality of first connecting pieces 261 in the same row are sequentially connected, if the same row comprises three first connecting pieces 261, four second connecting pieces 262 exist in the row, so that both sides of one first connecting piece 261 are respectively connected with one second connecting piece 262.
The plurality of first connectors 261 and the plurality of second connectors 262 may be flexible structures, so that the connecting structures 260 can be wound on the rotating shaft 250 when being retracted in the main body 240. One end of the second connectors 262 is detachably and fixedly connected with the rotating shaft 250, so that the detection area of the display panel can be matched by increasing or decreasing the second connectors 262 when the display area of the display panel is larger or smaller, the other end of the second connectors 262 is detachably and fixedly connected with the first connectors 261 on the same line, when the line connection problem occurs in the first connector 261, the point detection module 211 or the second connector 262, the disassembly and fixing connection between the second connector 262 and the rotating shaft 250 or between the second connector 262 and the first connector 261 can be realized, and the maintenance or the replacement can be completed.
In the process that the driving device 220 drives the plurality of spot-inspecting modules 211 in the detecting device 210 to move to the positions corresponding to the plurality of regions 110 to be detected, the driving device 220 may drive the rotating shaft 250 to rotate clockwise along the first direction, the plurality of second connecting members 262 in the connecting structure 260 rotate relative to the rotating shaft 250 at the same time, so as to drive the plurality of first connecting members 261 connected with the plurality of second connecting members 262 to move, and further drive the plurality of spot-inspecting modules 211 connected with the plurality of first connecting members 261 to extend out of the main body 240 from the inside of the main body 240, so that the plurality of spot-inspecting modules 211 move to the positions corresponding to the plurality of regions 110 to be detected, and thus the detection of the luminance values of the plurality of regions 110 to be detected is realized through the plurality of spot-inspecting modules 211.
Correspondingly, after the plurality of spot inspection modules 211 complete the fault detection of the plurality of regions 110 to be detected, the processor 230 may further control the driving device 220 to drive the rotating shaft to rotate along a second direction, for example, counterclockwise, and drive the plurality of first connecting members 261 and the plurality of spot inspection modules 211 to be wound from the outside of the main body 240 into the main body 240 through the plurality of second connecting members 262.
It should be noted that, in the process that the detection device 210 extends out of the main body 240 from the inside of the main body 240, if the display panel 100 is in a vertically placed 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 connection structure 260 to rotate, the connection structure 260 may drive the plurality of spot inspection modules 211 to move to the positions corresponding to the plurality of regions 110 to be detected by means of gravity. If can't realize the transmission with the help of gravity, that is to say that display panel is in the horizontality or main part 240 sets up the left side at display panel, right side or downside, then can set up support piece in main part 240, drive pivot 250 rotation in-process at drive arrangement 220, connection structure 260 can follow support piece and stretch out outside main part 240 in the main part 240 jointly, and support piece can play the supporting role to connection structure 260, thereby guarantee that connection structure 260 can move to preset position, connection structure 260 drives a plurality of some and examines the module 211 and move to the position that corresponds with a plurality of regions 110 of waiting to detect, concrete support piece's support mode does not do not specifically limit here.
It should be further noted that the connection structure 260, such as the first connection element 261 and the second connection element 262, may be made of a conductive material, so that the luminance data of the region to be detected 110 acquired by the spot inspection module 211 can be transmitted to the memory, so as to implement processing on the luminance data through the processor 230.
In addition, since the plurality of regions to be inspected 110 in the display panel 100 are arranged in an array, the plurality of regions to be inspected are distributed in a plurality of rows, and the main body of the failure detection system 200 is disposed at the upper side of the display panel, if the number of the plurality of spot inspection modules 211 in the detection device 210 is the same as the number of the plurality of regions to be detected, the processor 230 may control the driving device 220 to drive the rotating shaft 250 to rotate in a first direction, the plurality of first connecting pieces 261 and the plurality of spot inspection modules 211 are driven by the plurality of second connecting pieces 262 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 correspond to the plurality of regions to be inspected 110 one by one, obtain a plurality of luminance data of the plurality of regions to be inspected 110 detected by the plurality of spot inspection modules 211, determine whether abnormal luminance data exists in the plurality of luminance data, and if so, take the region to be inspected 110 corresponding to the abnormal luminance data as a target failure region.
The detection method of the fault detection system 200 is to set a plurality of spot detection modules 211 corresponding to a plurality of areas 110 to be detected in an equal number, so as to detect faults of the display panel 100 at one time. Of course, in order to save the detection cost, the number of the spot inspection modules 211 may also be reduced on the basis of ensuring the automatic detection of the fault detection system 200, that is, the number of the spot inspection modules 211 is the same as that of the plurality of regions 110 to be detected in the same row.
