It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more.

The display device detection system and the display device detection method provided by the embodiment of the application are described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1 to 6, the embodiment of the application discloses a display device detection system, which comprises a bearing device 100 and a data acquisition device, wherein the bearing device 100 comprises a mounting piece 110 and a bearing piece 120, and the bearing piece 120 is used for bearing a display device so that the display device can rotate around a central axis of the bearing piece 120. Specifically, rotation of the display device about the central axis of the carrier 120 may cause the data collector 210 to acquire display parameters of the peripheral region of the display device, thereby simulating the use environment of a user viewing the display device on different sides of the display device.
Rotating the display device about the central axis of the carrier 120 here includes at least two embodiments, one of which is: the carrier 120 is provided with a rotation rail in a ring shape around its central axis, and the display device is provided on the rotation rail to rotate the display device around the central axis of the carrier 120. It should be noted that, the rotation track may be fixedly disposed on the carrier 120, and at this time, the display device may be controlled to slide relative to the rotation track so as to rotate around the central axis of the carrier 120; alternatively, the driving mechanism may be further used to drive the rotation rail to rotate around the central axis of the carrier 120, where the display device is fixed to the rotation rail to rotate around the central axis of the carrier 120; and the second is: the bearing piece 120 is rotationally connected with the mounting piece 110 by adopting the mounting rotating shaft 111, the axis of the mounting rotating shaft 111 coincides with the central axis of the bearing piece 120, and after the display device is positioned and arranged on the bearing piece 120, the bearing piece 120 is driven to rotate around the mounting rotating shaft 111, so that the display device can rotate around the central axis of the bearing piece 120.
The data collection device includes a data collector 210 and a collector support 220, wherein an optical inlet of the data collector 210 may be disposed toward the carrier 120, that is, light passing through the display device may enter the optical inlet of the data collector 210.
The data collector 210 is rotatably disposed on the collector support 220 to adjust the incident angle of the light entering the light inlet through the display device. Specifically, the data collector 210 may be rotatably disposed on the collector support 220 through the second pitch rotation shaft 201, and the data collector 210 may be rotated in pitch relative to the collector support 220 through the second pitch rotation shaft 201, that is, the data collector 210 may be rotated in a head-up direction or a head-down direction around the second pitch rotation shaft 201, so that the light entrance faces different areas of the carrier 120, thereby adjusting the incident angle of the light entering the light entrance through the display device. Alternatively, the axial direction of the second pitch rotation shaft 201 may extend in the horizontal direction.
And/or, the bearing member 120 is rotatably disposed on the mounting member 110 to adjust the incident angle of the light entering the light inlet through the display device. Specifically, the carrier 120 may be rotatably disposed on the mounting member 110 through the first pitch rotation shaft 101, and the carrier 120 may be rotated in a pitching manner relative to the collector frame 220 through the first pitch rotation shaft 101, that is, the carrier 120 may be rotated in a lifting manner or a lowering manner about the first pitch rotation shaft 101, so that the light entrance faces different areas of the carrier 120, and thus, the incident angle of the light entering the light entrance through the display device is adjusted. Alternatively, the axial direction of the first pitch rotation shaft 101 may extend in the horizontal direction. Of course, the carrier 120 may be rotatably disposed on the mounting member 110 through a cardan shaft, which is not limited in the specific manner of rotationally connecting the carrier 120 and the mounting member 110.
It should be noted that, the technical solution that the carrier 120 may be rotatably disposed on the mounting member 110 through the first pitch rotation shaft 101 may be combined with the technical solution that the carrier 120 and the mounting member 110 are rotationally connected by using the mounting rotation shaft 111, where the mounting rotation shaft 111 is connected with the first pitch rotation shaft 101, so as to respectively implement rotation of the display device around the mounting rotation shaft 111, and pitch rotation of the carrier 120 around the first pitch rotation shaft 101, for example: the mounting shaft 111 may be rotatably sleeved directly in the first pitch shaft 101, or the two may be connected using a connector.
In this embodiment of the present application, the carrying device 100 includes a mounting member 110 and a carrying member 120, the carrying member 120 may carry a display device, and in the case that the display device is disposed on the carrying member 120, the display device may rotate around a central axis of the carrying member 120, that is, the display device may rotate around its central axis through the carrying member 120, the data collecting device includes a data collector 210 and a collector support 220, and an optical inlet of the data collector 210 may be disposed towards the carrying member 120, so that the data collector 210 may receive light passing out from the display device, thereby detecting display parameters of the display device.
The carrier 120 is rotatably disposed on the mounting member 110 to adjust an incident angle of the light entering the light inlet through the display device, that is, the relative orientation between the carrier 120 and the light inlet can be adjusted by rotating the carrier 120, so that different areas of the carrier 120 and the display device face the light inlet, and the data collector 210 can detect the display parameters of the display device at different viewing angles. And/or, the data collector 210 is rotatably disposed on the collector support 220 to adjust the incident angle of the light entering the light inlet through the display device, that is, the relative orientation between the carrier 120 and the light inlet can be adjusted by rotating the data collector 210, so that different areas of the carrier 120 and the display device face the light inlet, and the data collector 210 can detect the display parameters of the display device under different viewing angles. Therefore, the present application can make the data collector 210 detect the display parameters of the display device under different viewing angles by rotating the carrier 120 or the data collector 210, so as to obtain an accurate detection result.
In order to detect the brightness parameter or color shift parameter of the display screen 310 in the real use environment, referring to fig. 1, the display screen 310 includes a display screen body 311 and an anti-reflection film 312. Specifically, the antireflection film 312 includes a third polarizing device 330 and a phase difference compensation film 320 stacked one on another, the phase difference compensation film 320 being stacked on the display panel main body 311; wherein, the third polarizing device 330 and the first polarizing device 230 and the second polarizing device 430 described below may be polarizers, and the phase difference compensation film 320 may be a quarter wave plate. The display panel body 311 may be an LCD panel, an OLED panel, or the like.
The carrier 120 and the data collector 210 are arranged in a staggered manner in the horizontal direction and the vertical direction, and the data collector 210 is a brightness meter 211 or an image sensor. In this embodiment, the carrying member 120 and the data collector 210 are disposed in a staggered manner in both the horizontal direction and the vertical direction, that is, the carrying member 120 and the data collector 210 are disposed at intervals in an oblique direction, so that the real use environment of the display screen 310 can be simulated.
The specific operation process is as follows, the display screen 310 is controlled to be in a lighting state, and at this time, the light emitted by the display screen 310 can be obliquely injected into the light inlet of the data collector 210; the display screen 310 is controlled to rotate around the central axis of the carrier 120, so that the data collector 210 obtains display parameters of a circumferential area of the display screen 310, where the circumferential area of the display screen 310 refers to: the area of the display screen 310 facing the light inlet is rotated about the central axis of the carrier 120 to create a circumferential area that simulates the brightness parameter or color shift parameter of a user looking at the display device on different sides of the display device. Here, the luminance parameter is acquired by the luminance meter 211; the color shift parameter is obtained by an image sensor, specifically, the image sensor may collect a color shift map of the display screen 310, and then may obtain the color shift parameter of the display screen 310 by the color shift map.
In the above embodiment, after the display screen 310 is placed on the carrier 120 and the display screen 310 is in the on state, the display screen 310 is controlled to rotate around the central axis of the carrier 120, and when the brightness parameter or the color shift parameter of the different display screens 310 is obtained, since the initial position of the different display screens 310 on the carrier 120 may be different when the display screen 310 is placed each time, the angle of the transmission axis of the third polarization device 330 of the different display screens 310 may be different, which is inconvenient for comparing the brightness parameter and the color shift parameter of the different display screens 310 under different transmission axis angles.
In an alternative embodiment, the data acquisition device further includes a first bracket and a first polarizing device 230, the first polarizing device 230 being located between the data acquisition device 210 and the carrier 120 and opposite the light inlet, the first polarizing device 230 being detachably provided on the first bracket. In this embodiment, the first polarizer 230 is located between the data collector 210 and the carrier 120 and opposite to the light inlet, so that light emitted by the display screen 310 will first pass through the first polarizer 230 and then enter the light inlet, and the first polarizer 230 is disposed on the first bracket and can rotate around its central axis, and by rotating the display screen 310, an angle between the vertical orthographic projection of the light transmission axis of the third polarizer 330 of the display screen 310 and the vertical orthographic projection of the light transmission axis of the first polarizer 230 can be adjusted, and the angle can be 0 degrees, 45 degrees, 90 degrees, etc. And because the display screen 310 is provided with the third polarizing device 330, the brightness of the first light-emitting side of the first polarizing device 230 will change during the rotation of the display screen 310, so that after different display screens 310 are placed on the carrier 120, each display screen 310 can be rotated to the same position of the brightness of the first light-emitting side, so that different display screens 310 are all positioned at the same initial position, at this time, the angles of the light transmission axes of different display screens 310 at the initial position are the same, and when different display screens 310 are rotated by the same angle, the angles of the light transmission axes of different display screens 310 are the same under the same angle, thereby facilitating comparison of brightness parameters and color cast parameters of different display screens 310 under different angles of the light transmission axes.
Taking the initial position as an example, the display screens 310 are rotated to the first position with the highest brightness at the first light emitting side, the specific operation procedure is as follows: after the display screen 310 is placed on the carrier 120 and the display screen 310 is in the on state, the display screen 310 is turned, and the brightness of the first light emitting side of the first polarizer 230 is obtained, the first polarizer 230 is removed, and the display screen 310 is turned to the first position with the highest brightness of the first light emitting side, where the polarization direction of the third polarizer 330 on the display screen 310 is the same as the polarization direction of the first polarizer 230, that is: in the vertical direction, the front projection of the light transmission axis of the third polarizing device 330 of the display screen 310 is parallel to the front projection of the light transmission axis of the first polarizing device 230, then the first polarizing device 230 is detached from the first bracket, and the display screen 310 is controlled to rotate around the central axis of the carrier 120 again, so that the brightness parameter or the color cast parameter is obtained through the brightness meter 211 or the image collector 212.
It should be noted that the first bracket may be an integral structure with the collector bracket 220, or may be a split structure.
Further, the first polarizer 230 is rotatably connected to the first bracket, so that the first polarizer 230 rotates around its central axis, and before the display screen 310 is located at the initial position, the light transmission axis of the first polarizer 230 can be set to 0 degrees, so that when the display screen 310 is located at the first position, the light transmission axis of the third polarizer 330 of the display screen 310 is also set to 0 degrees, and therefore, in the process of rotating the display screen 310, the degree of rotation of the display screen 310 is the degree of rotation of the third polarizer 330 thereon, so that it is more convenient to compare the brightness parameters and the color cast parameters of different display screens 310 under different angles of the light transmission axis.
In an alternative embodiment, referring to fig. 2, the data collector 210 is an image collector 212, the display device is a display screen 310, and the display screen 310 includes a display screen main body 311 and an antireflection film 312. Specifically, the structure of the antireflection film 312 is the same as that of the antireflection film 312 described above, and the detailed structure of the antireflection film 312 will not be described in detail.
The display device detection system further includes a light emitting device 400, where the light emitting device 400 includes a light emitting source 410 and a light source bracket 420, and a light outlet of the light emitting source 410 can be disposed towards the carrier 120, and the light emitting source 410 is rotatably disposed on the light source bracket 420 to adjust an outgoing angle of light emitted by the light emitting source 410. Specifically, the light source 410 may be rotatably disposed on the light source support 420 through the third pitching rotation shaft 401, and the light source 410 may be rotated in a pitching manner relative to the light source support 420 through the third pitching rotation shaft 401, that is, the light source 410 may be rotated in a head raising manner or a head lowering manner about the third pitching rotation shaft 401, so that the light outlets of the light source 410 face different areas of the carrier 120, and the light emitting angle of the light emitted by the light source 410 is adjusted, so as to simulate the light emitted to the display screen 310 at different angles in the external environment. Alternatively, the axial direction of the third pitch rotation shaft 401 may extend in the horizontal direction.
The carrier 120 and the light source 410 are disposed offset in both the horizontal and vertical directions. In this embodiment, the carrier 120 and the light source 410 are both disposed in a staggered manner in the horizontal direction and the vertical direction, that is, the carrier 120 and the light source 410 are distributed at intervals in an oblique direction, and the light emitted by the light source 410 is obliquely emitted to the carrier 120 and the display screen 310, so that the real use environment of the display screen 310 can be simulated, the color cast parameter of the display screen 310 in the real use environment can be obtained through the image sensor, and the integral black effect of the display screen 310 can be further determined.
The specific operation process is as follows, the display screen 310 is placed on the carrier 120 and the display screen 310 is controlled to be in a dark state, the light source 410 is turned on, at this time, the light emitted by the light source 410 is obliquely incident on the display screen 310, and then reflected by the display screen 310 to enter the light inlet; the display screen 310 is controlled to rotate around the central axis of the carrier 120, so that the data collector 210 obtains color cast parameters of the circumferential area of the display screen 310, and when light rays in the simulated external environment are emitted to the display screen 310 on different sides of the display device, the color cast parameters of the display screen 310 are obtained, and further, the integral black effect of the display screen 310 is judged. The dark state here means: the display screen 310 is in an off state or the display screen 310 is in an on state, but the display screen 310 displays a black screen, that is: the liquid crystal layer is turned off.
In the above embodiment, the light emitting source 410 emits natural light, and the stray light in the natural light is more, so as to reduce the interference of the stray light on the image collector 212, in an alternative embodiment, the light emitting apparatus 400 further includes a second bracket and a second polarization device 430, where the second polarization device 430 is located between the light emitting source 410 and the carrier 120 and opposite to the light outlet, and the second polarization device 430 is disposed on the second bracket and can rotate around its central axis. Optionally, the rotation structure between the second polarizer 430 and the second bracket is the same as the rotation structure between the display device and the carrier 120, and will not be described in detail herein.
In this embodiment, the second polarizing device 430 is disposed between the light emitting source 410 and the carrier 120, so that the light emitted by the light emitting source 410 is emitted to the display screen 310 through the second polarizing device 430, and the light passing through the second polarizing device 430 is converted into linear polarized light, so that the interference of stray light on the image collector 212 can be reduced.
The specific operation process is as follows, the display screen 310 is placed on the carrier 120 and the display screen 310 is controlled to be in a dark state, the light source 410 is turned on, the second polarizer 430 is turned and the brightness of the second light emitting side of the display screen 310 is obtained, and because the third polarizer 330 is provided on the display screen 310, the brightness of the second light emitting side of the display screen 310 changes in the process of turning the second polarizer 430, after different display screens 310 are placed on the carrier 120, each display screen 310 can be turned to the same position of the brightness of the second light emitting side, so that different display screens 310 are all located at the same initial position, at this time, the angles of the light transmission axes of different display screens 310 are all the same at the initial position, the angles of the light transmission axes of different display screens 310 are also the same at the same angles, and the second polarizer 430 is controlled to synchronously turn, so that the color cast parameters of different display screens 310 under different light transmission axes are conveniently compared.
When the polarization direction of the second polarizer 430 is identical to the polarization direction of the third polarizer 330 of the display screen 310, the linearly polarized light passing through the second polarizer 430 is obliquely incident into the third polarizer 330 and the phase difference compensation film 320, and then reflected by the display screen main body 311, and the reflected light is obliquely incident into the phase difference compensation film 320 and then is directed to the second polarizer, and since the light is obliquely incident into the phase difference compensation film 320, the polarized light emitted to the second polarizer through the phase difference compensation film 320 is not perpendicular to the polarization direction of the third polarizer 330, and therefore, a part of the light is emitted from the third polarizer 330 to enter the light inlet, and at this time, the brightness of the second light-emitting side of the display screen 310 is the highest; when the polarization direction of the second polarization device 430 is perpendicular to the polarization direction of the third polarization device 330 of the display screen 310, the linearly polarized light passing through the second polarization device 430 cannot pass through the third polarization device 330 and is absorbed by the third polarization device 330, and at this time, the brightness of the second light emitting side of the display screen 310 is the lowest.
