Technical Field

[0001] The present application relates to the field of display correction technology, and in particular to a display correction device. Background Art

[0002] With the rapid development of display technology, various display devices have become increasingly ubiquitous in people's lives. For example, a display device can be formed by multiple interconnected display modules. Due to manufacturing process differences, there may be a certain degree of image deviation between multiple display modules, which can lead to inconsistent color and brightness in the overall display image of the display device.

[0003] In order to make the brightness and color of the displayed image more uniform, a calibration device is required to perform image calibration on the display device. However, the existing calibration device has a low degree of automation during the calibration process of the display device image, and requires many steps to be completed by manual assistance, making the entire calibration process inefficient. Utility Model Content

[0007] In the display correction device of the embodiment of the present application, the display to be corrected can be arranged on the carrier assembly, so that it can be rotated under the drive of the carrier drive mechanism. Since the detection box chamber is located on one side of the carrier assembly along the direction of the rotation axis of the carrier assembly, the display to be corrected is moved to the detection chamber of the detection box chamber through the placement port of the detection box chamber close to one end of the carrier assembly.

[0015] In some embodiments, the detection mechanism further includes a light gun and a second detection adjustment mechanism.

DETAILED DESCRIPTION

[0027] In the embodiments of this application, the terms "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0028] In the description of the embodiments of this application, the term "and / or" refers to and encompasses any and all possible combinations of one or more of the associated listed items. The term "and / or" describes an association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects are in an "or" relationship.

[0029] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0030] In the description of the embodiments of the present application, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element limited by the statement "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In the absence of further restrictions, an element limited by the statement "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0031] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within ±10°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within ±10°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one.

[0032] A display device is a device used to display images. Depending on the principles of the display device, the display device can have different components. For example, the display device may include multiple light-emitting devices. The light-emitting devices can emit light to form a display image.

[0033] The light-emitting device may include a light-emitting diode. Depending on the size of the light-emitting diode, the light-emitting diode can be divided into a mini light-emitting diode (Mini-LED) and a micro light-emitting diode (Micro-LED). The size of a Mini-LED can range from 50 microns to 200 microns, while the size of a Micro-LED can be less than 50 microns. Furthermore, the driver chip of the display device can have different packaging methods. For example, the driver chip can be directly packaged on a glass substrate, i.e., a chip on glass (COG).

[0034] As can be seen from the above, the display screen of a display device can be formed by emitting light from multiple light-emitting devices. Under the same light source and the same background color, the different degrees of color difference on the display screen perceived by the visual sense is called Mura.

[0035] It is known that various factors of the display device may cause the mura phenomenon to appear on the display screen. For example, in the related art, the display device can be formed by splicing a plurality of COG modules that are spliced ​​together. In some cases, due to factors such as the manufacturing process of the light-emitting device of the COG module, the packaging process factors (such as the amount of tin, position deviation, welding temperature and the influence of glue during the packaging process), and the inconsistency of the current and voltage when the light-emitting device emits light, the display screen will have uneven colors. In addition, the differences in chromaticity and brightness between multiple COG modules will also cause uneven and unsmooth display screens.

[0036] Demura is a technology that eliminates mura from the display screen and makes the display screen brightness more uniform. Demura adjusts the grayscale value or voltage of the pixel points in the mura area of ​​the display screen to brighten the relatively dark area or darken the relatively bright area, thereby achieving a uniform display effect. However, the correction equipment used in the related art to correct the display screen has a low degree of automation during the correction process, and requires many steps to be completed by manual assistance, such as manually moving the display, resulting in low efficiency of the entire correction process.

[0037] Based on this, the embodiment of the present application provides a display correction device, such as Figure 1 As shown, Figure 1 The present invention provides a schematic structural diagram of a display calibration device 100 according to an embodiment of the present invention. The display calibration device 100 may include a carrier assembly 10. The carrier assembly 10 may be used to place a display to be calibrated. For example, the display may be placed above the carrier assembly 10.

[0038] like Figure 2 As shown, Figure 2 This is one of the partial structural diagrams of a display calibration device 100 provided in an embodiment of the present application. The display calibration device 100 may further include a bearing drive mechanism 20. The bearing drive mechanism 20 is connected to the bearing assembly 10 and is used to drive the bearing assembly 10 to rotate. For example, Figure 2 As shown, the rotation axis of the bearing assembly 10 can be Figure 2 The up and down directions shown are parallel.

[0039] Therefore, when the display to be calibrated is placed on the supporting assembly 10, the supporting drive mechanism 20 can drive the supporting assembly 10 to rotate, and then drive the display to be calibrated to rotate, so that the display to be calibrated can be rotated to the required position without manual transportation of the display, with a higher degree of automation and higher movement efficiency.

[0040] The composition of the bearing drive mechanism 20 can be selected according to actual conditions. In some embodiments, the bearing drive mechanism 20 can include a bearing drive motor. The output end of the bearing drive motor can be connected to the bearing assembly 10 to drive the bearing assembly 10 to rotate.

[0041] It is understandable that the type of the load-bearing drive motor can be selected according to actual conditions. For example, the load-bearing drive motor can be a direct drive rotary motor (DDR motor). The DDR motor has a high rotation accuracy and can more accurately control the rotation angle of the load-bearing component 10 to ensure high-precision rotation. The rotation accuracy of the DDR motor can be ±4 arcsec. Of course, the load-bearing drive motor can also be other types of motors, which drive the load-bearing component 10 to rotate by indirect drive.

[0042] Reference Figure 1 ,In order to provide a darkroom environment for the display during the inspection process, such as Figure 1 As shown, the display calibration device 100 may further include a detection chamber 30. Along the direction of the rotation axis of the supporting assembly 10, the detection chamber 30 is located on one side of the supporting assembly 10. For example, Figure 1 As shown, the inspection chamber 30 is located above the carrier assembly 10. The interior of the inspection chamber 30 forms a test chamber, which provides a darkroom environment for the display. One end of the inspection chamber 30, near the carrier assembly 10, has a placement opening that communicates with the test chamber. This allows the display to be placed on the carrier assembly 10 and positioned within the test chamber through the placement opening, facilitating subsequent testing.

[0043] In addition, in order to test the display to be calibrated, Figure 3 As shown, Figure 3 This is a second partial structural diagram of a display calibration device 100 provided in an embodiment of the present application. The display calibration device 100 may further include a detection mechanism 40. The detection mechanism 40 is disposed in the detection chamber 30 and is used to detect the display screen of the display so as to calibrate the display.

[0044] Based on this, the display correction device 100 provided in the embodiment of the present application, the display to be corrected can be set on the carrier assembly 10, so that it can be rotated under the drive of the carrier drive mechanism 20. Since the detection chamber 30 is located on one side of the carrier assembly 10 along the direction of the rotation axis of the carrier assembly 10, the display to be corrected is moved to the detection chamber of the detection chamber 30 through the placement port of the detection chamber 30 near one end of the carrier assembly 10. Since the detection mechanism 40 is set in the detection chamber 30, the detection mechanism 40 can detect the display screen of the display to correct the display. After the display is detected, the display can be moved out of the detection chamber using the carrier drive mechanism 20, making it convenient for the staff to take it away. Thus, the display correction device 100 provided in the embodiment of the present application can drive the carrier assembly 10 to rotate through the carrier drive mechanism 20, so that the display placed on the carrier assembly 10 can be moved to a specified position along with the carrier assembly 10, without the need for manual transport of the display back and forth, thereby improving the degree of automation and also improving the detection efficiency.

[0045] In order to facilitate the smooth movement of the display into the detection chamber of the detection box chamber 30, as shown in FIG. Figure 1 As shown, in some embodiments, the detection chamber 30 may include a main body 31, a seal drive assembly 32, and a seal 33. The interior of the main body 31 forms the aforementioned detection chamber and defines the aforementioned placement opening. The main body 31 is spaced apart from the carrier assembly 10. This allows a display placed on the carrier assembly 10 to avoid the main body 31 and move to a position opposite the placement opening of the main body 31 during rotation.

[0046] The sealing drive assembly 32 is arranged on the box body 31. The sealing member 33 is located at one end of the box body 31 close to the bearing assembly 10, is arranged around the placement opening, and is connected to the sealing drive assembly 32. The specific position of the sealing member 33 can be set according to actual conditions. For example, Figure 1 As shown, the sealing member 33 is annular and can be sleeved on the periphery of the box body 31. Alternatively, the sealing member 33 can also be located on the inner side of the box body 31.

[0047] The seal drive assembly 32 is used to drive the seal 33 toward or away from the carrier assembly 10, so that the seal 33 abuts against or separates from the carrier assembly 10. Therefore, when the display needs to be moved into or removed from the detection chamber, the seal drive assembly 32 can drive the seal 33 away from the carrier assembly 10. At this time, a certain distance can be left between various parts of the detection chamber 30 and the carrier assembly 10, allowing the display to avoid the detection chamber 30 and enter the detection chamber.

[0048] Conversely, when inspecting a display, the seal drive assembly 32 can drive the seal 33 away from the carrier assembly 10. At this point, the seal 33 can abut against the carrier assembly 10. In this way, the seal 33, the box body 31, and the carrier assembly 10 form a relatively sealed inspection chamber, creating a highly effective darkroom environment and ensuring effective display inspection.

[0049] It is understood that the specific structure of the seal drive assembly 32 can be selected based on actual circumstances. For example, the support drive mechanism 20 can include a cylinder. Thus, the movement of the cylinder drives the seal 33 to reciprocate. Of course, the support drive mechanism 20 can also drive the seal 33 to move using other methods, which will not be further described here.

[0050] Generally, to ensure the accuracy of the test results, the test chamber is a darkroom environment with a lighting condition of less than 5 lumens. Therefore, to ensure that the seal 33, the box body 31, and the carrier assembly 10 can form a relatively closed test chamber, the box body 31 can be formed by connecting multiple sheet metal parts, wherein a sealing baffle is provided at the connection between the sheet metal parts to prevent external light from entering the interior of the test chamber. At the same time, the threading holes on the box body 31 can be threaded with a hose to ensure sealing. In addition, the seal 33 can be made of a sponge material to prevent the entry of light.

[0051] In order to ensure the stability of the bearing assembly 10, in some embodiments, as Figure 2 As shown, the display calibration device 100 may further include a support member 50 and a plurality of legs 60. The support drive mechanism 20 may be disposed on the support member 50. The plurality of legs 60 are disposed on a side of the support member 50 away from the support assembly 10 and are connected to the support member 50. Thus, the plurality of legs 60 provide good support for the support member 50, thereby maintaining a stable state of the support drive mechanism 20 and the support assembly 10 disposed on the support member 50.

[0052] To ensure better support for the support member 50, in some embodiments, the support member 50 may be made of marble. Marble has excellent shock resistance and rigidity, providing enhanced shock absorption. Furthermore, marble's stable structure, high surface finish accuracy, and resistance to rust also well meet the requirements of the display calibration device 100. Of course, the support member 50 may also be made of other materials, which will not be further described here.

[0053] It is understandable that the number of legs 60 can be set according to actual conditions. Figure 2As shown, the support member 50 may be rectangular. There may be four legs 60 disposed around the support member 50 and located at the four corners of the support member 50 .

[0054] In some embodiments, the support leg 60 may include an air-floating shock absorber. Thus, the air-floating shock absorber can provide a better shock-absorbing effect on the support leg 60, thereby better ensuring the stability of the support member 50 and reducing the probability of its shaking. At the same time, the air-floating shock absorber can prevent external vibrations from causing shaking on the detection mechanism 40, etc., which may affect the detection of the detection mechanism 40. Of course, the support leg 60 may also include other structures with a shock-absorbing effect. For example, the support leg 60 may also include a shock-absorbing spring. In this case, the support leg 60 can also provide a better shock-absorbing effect.

[0055] In some embodiments, as Figure 2 As shown, the display calibration device 100 may further include a support mechanism 70. The support mechanism 70 may be disposed on the support member 50, between the support member 50 and the carrier assembly 10. The support mechanism 70 abuts against the carrier assembly 10 to support the carrier assembly 10. Thus, by providing the support mechanism 70, when the carrier assembly 10 is large, the support mechanism 70 can further support the carrier assembly 10, ensuring the stability of the carrier assembly 10 and preventing the carrier assembly 10 from shaking. This allows the height of each position to remain consistent when multiple displays are placed on the carrier assembly 10.

[0056] For example, Figure 2 As shown, there can be multiple supporting mechanisms 70. The multiple supporting mechanisms 70 are arranged at intervals in the circumferential direction of the bearing assembly 10. Thus, through the support of the multiple supporting mechanisms 70 at different positions, a better supporting effect can be achieved.

[0057] Furthermore, the support mechanism 70 can have different compositions. In some embodiments, the support mechanism 70 can include a cylinder. The cylinder can provide a good support effect for the load-bearing assembly 10. Alternatively, the support mechanism 70 can include a spring. The elasticity of the spring can also provide a good support effect for the load-bearing assembly 10.

[0058] Reference Figure 1 and Figure 3 In some embodiments, there may be multiple detection chambers 30 and multiple detection mechanisms 40. One detection mechanism 40 is disposed in one detection chamber 30. Multiple detection chambers 30 are spaced apart along the rotation direction of the carrier assembly 10.

[0059] Thus, when using the display calibration device 100 for testing, multiple displays to be tested can be placed on the carrier assembly 10. In this case, the carrier assembly 10 can drive the multiple displays to rotate and enter different test chambers 30 for simultaneous testing, thereby further improving the testing efficiency.

[0060] It is understandable that the number of detection chambers 30 can be set according to actual needs. Figure 1 and Figure 3 As shown, there can be three inspection chambers 30. The three inspection chambers 30 are spaced apart along the rotational direction of the carrier assembly 10. The three inspection chambers 30 can be spaced 90° apart, meaning that starting from the first inspection chamber 30, a new inspection chamber 30 is added every 90° along the rotational direction of the carrier assembly 10. For example, the three inspection chambers 30 are located on the left, right, and rear sides, respectively. In this case, the front side can be used as a placement location, allowing users to place the display to be inspected.

[0061] In some embodiments, as Figure 2 As shown, the carrier assembly 10 may include a carrier 11 and a fixing assembly 12. The carrier 11 may be connected to a carrier drive mechanism 20. Thus, the carrier 11 may rotate under the drive of the carrier drive mechanism 20. The fixing assembly 12 may be disposed on a side of the carrier 11 near the detection chamber 30 and connected to the carrier 11. The fixing assembly 12 may be used to secure the display. Thus, the fixing assembly 12 may better secure the display to the carrier 11, ensuring stable rotation of the display.

[0062] In addition, if Figure 2 As shown, there can be multiple fixing components 12. In this way, when multiple displays are calibrated at the same time, they can be fixed by multiple fixing components 12 to ensure that the multiple display screens can rotate stably.

[0063] In some embodiments, as Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of a fixing assembly 12 provided in an embodiment of the present application. The fixing assembly 12 may include a first fixing member 121 and a second fixing member 122. The first fixing member 121 may be connected to the carrier 11. The second fixing member 122 is disposed on a side of the first fixing member 121 away from the carrier 11 and is slidably connected to the first fixing member 121. The second fixing member 122 may be used to position a display.

[0064] For example, based on Figure 1 and Figure 4 As shown, the second fixing member 122 can be along Figure 1The front and rear directions of the second fixing member 122 are connected to the first fixing member 121 for sliding. Therefore, when placing the monitor to be calibrated, the staff can pull the second fixing member 122 so that the second fixing member 122 slides relative to the first fixing member 121, so that the staff can place the monitor more conveniently. After placing the monitor, the staff can push the second fixing member 122 to retract the second fixing member 122 to its original position. Figure 2 As shown, a handle 124 may be provided on one side of the second fixing member 122. In this way, the user can hold the handle 124 to drive the second fixing member 122 to slide, making the operation more convenient.

[0065] In order to enable the second fixing member 122 to fix the display. In some embodiments, Figure 4 As shown, the fixing assembly 12 may further include a plurality of limiting blocks 123. The plurality of limiting blocks 123 are disposed on a side of the second fixing member 122 away from the first fixing member 121 and are spaced apart circumferentially around the second fixing member 122.

[0066] In this way, when the display is placed on the second fixing member 122, multiple limit blocks 123 can be located around the periphery of the display, which can limit the display and prevent the display from shaking or displacing during the rotation of the second fixing member 122, thereby ensuring the stable position of the display.

[0067] For example, Figure 4 As shown, the second fixing member 122 may be a rectangular structure, and the limiting block 123 may be an L-shaped structure, located at a corner of the second fixing member 122. As an example, the limiting block 123 can accommodate a display with a maximum size of 800 mm×650 mm.

[0068] like Figure 4 As shown, in some embodiments, an air intake channel can be formed inside the second fixing member 122. An air intake port 1221 is provided on the surface of the second fixing member 122 on the side away from the first fixing member 121, connected to the air intake channel. Thus, through the air intake port 1221 and the air intake channel inside the second fixing member 122, air can be pumped out to reduce the pressure inside the air intake channel to less than the external atmospheric pressure, thereby allowing the display to be adsorbed on the surface of the second fixing member 122, allowing the display to be stably placed on the second fixing member 122.

[0069] Based on the above solution, since the display is mounted on the second fixing member 122 by adsorption, the display will not come into contact with other components. When the display includes a glass substrate, damage to the glass substrate from contact with other components can be avoided. If the display includes a housing, it can be fixed by means of a stopper 123.

[0070] It is understandable that the above-mentioned limit block 123 and the air intake channel can exist at the same time. In this way, the fixing component 12 can use different methods to fix different types of displays. Of course, the limit block 123 and the air intake channel can also exist in only one of them, and the specific choice can be made according to the actual situation. For example, Figure 2 As shown, there can be more than one fixing assembly 12 . Thus, the second fixing members 122 in a portion of the fixing assemblies 12 can be provided with the aforementioned air intake passage, while another portion of the fixing assemblies 12 can include a limiting block 123 .

[0071] In order to achieve the sliding connection between the second fixing member 122 and the first fixing member 121, in some embodiments, as shown in FIG. Figure 4 As shown, the first fixing member 121 may be formed with a sliding groove 1211. The groove wall of the sliding groove 1211 forms a limiting groove 1212. The second fixing member 122 may be located in the sliding groove 1211, with a portion located in the limiting groove 1212, and slidably connected to the limiting groove 1212.

[0072] Thus, through the cooperation between the sliding groove 1211 and the limiting groove 1212, the second fixing member 122 can be well slidably connected to the first fixing member 121, facilitating the sliding of the second fixing member 122. At the same time, the limiting groove 1212 can also play a limiting role, allowing the second fixing member 122 to slide better along the extending direction of the limiting groove 1212, thereby preventing the second fixing member 122 from sliding in other directions.

[0073] In some embodiments, as Figure 3 As shown, the detection mechanism 40 may include a charge coupled device (CCD) camera 41 and a first detection and adjustment mechanism 42. The CCD can compare the brightness of the display screen by taking pictures, thereby comparing whether there is a problem with the uniformity of the brightness at various locations, which can achieve a good correction effect.

[0074] The first detection and adjustment mechanism 42 is connected to the CCD camera 41 and is used to adjust the position of the CCD camera 41 in a first direction, a second direction, and a third direction. The first direction is parallel to the rotation axis of the support assembly 10. The first direction, the second direction, and the third direction are perpendicular to each other. Thus, the position of the CCD camera 41 can be adjusted by the first detection and adjustment mechanism 42 so that the CCD camera 41 can be positioned appropriately to capture the display, obtaining better data for calibration.

[0075] In some embodiments, as Figure 3As shown, the display calibration device 100 may further include a CCD frame 80, which may be connected to the first detection adjustment mechanism 42 and disposed on the support member 50 ( Figure 2 ). As can be seen from the above, support member 50 can be made of marble, which has good shock resistance and structural rigidity, ensuring the stability of CCD camera 41 and preventing it from shaking. Furthermore, as can be seen from the above, support leg 60 includes an air-floating shock absorber, which can minimize the impact of external shaking on the CCD camera, preventing the CCD camera 41 from shaking.

[0076] It is understood that the first detection and adjustment mechanism 42 can have different compositions. In some embodiments, Figure 3 As shown, the first detection adjustment mechanism 42 may include a first sub-adjustment mechanism 421 and a second sub-adjustment mechanism 422. The first sub-adjustment mechanism 421 may be connected to the CCD camera 41 to adjust the position of the CCD camera 41 in the first direction. The second sub-adjustment mechanism 422 may be connected to the first sub-adjustment mechanism 421 to adjust the position of the CCD camera 41 in the second and third directions.

[0077] Thus, the position adjustment of the charge coupled device camera 41 in the first direction, the second direction, and the third direction can be achieved through the first sub-adjustment mechanism 421 and the second sub-adjustment mechanism 422. Exemplarily, the first sub-adjustment mechanism 421 may include a servo motor. The servo motor can be used to more accurately control the adjustment position and ensure the accuracy of the position. The model of the servo motor can be selected according to actual conditions. For example, the servo motor can be a 17-bit absolute servo motor, the accuracy of its encoder can reach 0.00274°, and the accuracy of repeated positioning can be ±5 microns. Of course, the first sub-adjustment mechanism 421 can also include other components, as long as the adjustment function can be achieved, and no examples will be given here.

[0078] The second sub-adjustment mechanism 422 may include an XY manual fine-motion stage. This allows the XY manual fine-motion stage to independently adjust the position of the CCD camera 41 in the second and third directions. Of course, the second sub-adjustment mechanism 422 may also include other components, as long as they can achieve the adjustment function. Examples are not provided here.

[0079] In some embodiments, as Figure 5 As shown, Figure 5This is the third partial structural diagram of the display calibration device 100 provided in an embodiment of the present application. The detection mechanism 40 may also include a light gun 43 and a second detection and adjustment mechanism 44. The light gun 43 can accurately detect the brightness of each position on the display, thereby facilitating subsequent adjustment and correction of the brightness at each position of the display.

[0080] The second detection and adjustment mechanism 44 is connected to the light gun 43 and is used to adjust the position of the light gun 43 in the first, second, and third directions. The second detection and adjustment mechanism 44 can be used to adjust the position of the light gun 43 so that the light gun 43 can be positioned appropriately to capture the display and obtain better data for calibration.

[0081] In some embodiments, as Figure 5 As shown, the display calibration device may further include a light gun fixing frame 90. The light gun fixing frame 90 may be connected to the second detection adjustment mechanism 44, and the second detection adjustment mechanism 44 and the light gun 43 may be fixed by the light gun fixing frame 90. The light gun fixing frame 90 may be connected to the box body 31 ( Figure 3 ) connection, the box body 31 may be provided with an avoidance hole 311 ( Figure 3 ), the light gun fixing bracket 90 can be set at the avoidance hole 311, so that the second detection adjustment mechanism 44 and the light gun 43 can be located inside the box body 31 through the avoidance hole 311.

[0082] Similarly, the second detection and adjustment mechanism 44 may also have different compositions. Figure 5 As shown, the second detection and adjustment mechanism 44 may include a third sub-adjustment mechanism 441 and a fourth sub-adjustment mechanism 442. The third sub-adjustment mechanism 441 may be connected to the light gun 43 to adjust the position of the light gun 43 in the first direction. The fourth sub-adjustment mechanism 442 may be connected to the third sub-adjustment mechanism 441 to adjust the position of the light gun 43 in the second and third directions.

[0083] Thus, the third sub-adjustment mechanism 441 and the fourth sub-adjustment mechanism 442 can achieve position adjustment of the light gun 43 in the first, second, and third directions. For example, the third sub-adjustment mechanism 441 can include a servo motor. The servo motor can more precisely control the adjustment position, ensuring position accuracy. The servo motor model can be selected based on actual conditions. For example, the servo motor can be a 17-bit absolute servo motor, whose encoder accuracy can reach 0.00274° and repeatable positioning accuracy can reach ±5 microns. Of course, the first sub-adjustment mechanism 421 can also include other components as long as they can achieve the adjustment function, and no examples will be given here.

[0084] The fourth sub-adjustment mechanism 442 may include a high-precision linear motor and a grating ruler. The number of high-precision linear motors and grating rulers may be two. One high-precision linear motor and one grating ruler can work together to precisely adjust the position in the second direction, while another high-precision linear motor and another grating ruler can work together to precisely adjust the position in the third direction. Of course, the fourth sub-adjustment mechanism 442 may also include other components, as long as they can achieve the adjustment function, and these components will not be further illustrated here.

[0085] The following is an illustrative description of the operation and use of the display calibration device 100 provided in an embodiment of the present application with reference to the accompanying drawings.

[0086] Reference Figure 1 First, the staff can place the display to be calibrated on the fixing assembly 12 from the front. Before calibrating the display, the display can be subjected to a static elimination process.

[0087] then, Figure 1 The seal 33 shown on the left side of the middle rises under the drive of the seal drive assembly 32, and the display moves with the fixed assembly 12 into a detection chamber 30. Then, the seal 33 descends under the drive of the seal drive assembly 32 to form a closed detection chamber. Figure 3 ) may include a charge coupled device camera 41 ( Figure 3 ) and Light Gun 43 ( Figure 5 During the test, the optical parameters of the center of each light panel in the display can be collected using the light gun 43. The data collected by the light gun 43 is used as a standard. Then, the optical parameters captured by the charge coupled device camera 41 are combined to perform a calibration test on the display to calibrate the brightness and chromaticity.

[0088] The display then moves to Figure 1 The detection and calibration are performed in sequence in the detection chamber 30 at the rear and right to obtain the corresponding detection and calibration data. Figure 3 ) may include a charge coupled device camera 41 ( Figure 3 Of course, the detection mechanism 40 in the rear and right detection chamber 30 may also include a light gun 43 ( Figure 5 ).

[0089] Finally, the display is moved back to the front of the display calibration device 100, where data can be burned and static electricity can be removed. The display can then be removed from the display calibration device 100. It is understood that the display can be calibrated and adjusted based on the obtained calibration data using corresponding calibration software, and further explanation is omitted here.

[0090] Depend on Figure 1 It can be seen that Figure 1 The display calibration device 100 shown has multiple detection chambers 30. In this way, when the first display is moved to the detection chamber 30 on the left, the staff can set up another display to be calibrated in front. Figure 1 The solution shown can calibrate three displays simultaneously to ensure detection efficiency.
