Description

Technical Field

[0001] This utility model relates to the field of luminance and colorimeter technology, and in particular to an alignment device based on a colorimeter. Background Technology

[0002] In the prior art, when performing optical measurements on a display panel using a colorimeter, the center of the colorimeter probe needs to be aligned with a designated area on the display panel where the measurement is to be performed. Currently, visual alignment is usually used. However, since the outer diameter of the colorimeter probe is small, generally around 8mm-10mm, and the probe itself cannot emit light, the alignment accuracy is low. Utility Model Content

[0003] This invention provides an alignment device based on a colorimeter. The alignment device helps to align the main optical axis of the colorimeter probe with a designated area of ​​the detection position, thereby improving the alignment accuracy and thus improving the measurement accuracy.

[0004] In a first aspect, embodiments of the present invention provide a display panel, comprising:

[0005] Including alignment fixtures and laser detectors;

[0006] The alignment fixture includes a first interface and a second interface, the first interface being used to connect to the probe of the colorimeter, and the second interface being used to connect to the laser detector;

[0007] The alignment fixture is used to adjust the laser beam emitted by the laser detector to coincide with the main optical axis of the probe.

[0008] The alignment device provided in this embodiment includes a first interface and a second interface. The first interface is used to connect to the probe of a colorimeter, and the second interface is used to connect to a laser detector. The alignment fixture ensures that the laser beam emitted by the laser detector coincides with the principal optical axis of the probe. When aligning the colorimeter with the detection position, the laser detector is first aligned with the detection position. When the laser beam emitted by the laser detector illuminates a designated area of ​​the detection position, it indicates that the laser detector and the detection position are aligned. Since the laser beam emitted by the laser detector coincides with the principal optical axis of the probe, the principal optical axis of the probe is also aligned with the designated area of ​​the detection position. The alignment device can then be removed, and the colorimeter can be used to measure the color and / or brightness of the detection position, improving alignment accuracy and thus improving measurement accuracy.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be fully described below with reference to the accompanying drawings of the embodiments of this utility model and through specific implementation methods. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort fall within the protection scope of this utility model.

[0016] Figure 1 This is a simplified structural diagram of an alignment device provided in an embodiment of this utility model. See also... Figure 1 The alignment device includes an alignment fixture 10 and a laser detector 20. The alignment fixture 10 includes a first interface 110 and a second interface 120. The first interface 110 is used to connect the probe 100 of the colorimeter 01, and the second interface 120 is used to connect the laser detector 20. The alignment fixture 10 is used to adjust the laser beam b emitted by the laser detector 20 to coincide with the principal optical axis a of the probe 100.

[0017] Specifically, the alignment device includes an alignment fixture 10 and a laser detector 20. The alignment fixture 10 is primarily used to connect the colorimeter 01 and the laser detector 20, aligning the center of the laser detector 20 with the center of the probe 100 of the colorimeter 01. For example, as shown... Figure 1As shown, the alignment fixture 10 includes a first interface 110 and a second interface 120. The first interface 110 and the second interface 120 are located on opposite sides of the alignment fixture 10 along the vertical direction, and both the first interface 110 and the second interface 120 have openings in their respective orientations. A portion of the probe 100 of the colorimeter 01 is installed in the opening of the first interface 110 to connect the first interface 110 to the probe 100. Similarly, a portion of the laser detector 20 is installed in the opening of the second interface 120 to connect the second interface 120 to the laser detector 20. It is understood that the opening of the first interface 110 has a first geometric center line (not shown in the figure), and the probe 100 of the colorimeter 01 has a principal optical axis a. It is understood that the first geometric center line is the geometric center of the first interface 110. For example, when the first interface 110 is circular, the first geometric center line is the axis of the circle; when the first interface is rectangular, the first geometric center line is the vertical line where the intersection of the diagonals of the rectangle is located. The principal optical axis is the axis of symmetry of the internal optical elements (such as lenses, gratings, filters, sensors, etc.) of the probe 100, and it is also the reference path for light transmission and focusing. In other words, when the principal optical axis of the probe 100 is aligned with the designated area of ​​the detection position, the probe 100 is aligned with the detection position.

[0018] In one embodiment, the probe 100 is fixed at the center of the first interface 110 by aligning its first geometric center line with the principal optical axis a of the probe 100. Similarly, the second interface 120 has a second geometric center line, and the laser detector 20 can emit a laser beam. During installation, the laser detector 20 is fixed at the center of the second interface 120 by aligning its second geometric center line with the laser beam b of the laser detector 20. Furthermore, based on the above-mentioned alignment of the first geometric center line of the first interface 110 with the principal optical axis a of the probe 100 and the second geometric center line of the second interface 120 with the laser beam b of the laser detector 20, the first geometric center line of the first interface 110 is aligned with the second geometric center line of the second interface 120, meaning the first interface 110 and the second interface 120 are coaxially arranged, thereby ensuring that the laser beam b emitted by the laser detector 20 coincides with the principal optical axis a of the probe 100. Thus, when aligning the probe 100 with the detection position, the laser detector 20 can be aligned with the detection position first. This involves moving the spot of the laser beam b emitted by the laser detector 20 at the detection position to the designated area of ​​the detection position, thereby aligning the laser detector 20 with the detection position. Since the laser beam b emitted by the laser detector 20 coincides with the principal optical axis a of the probe 100, the principal optical axis a of the probe 100 is also aligned with the designated area of ​​the detection position. Afterward, the alignment device is removed, and the chromaticity and / or luminance of the detection position are measured using the colorimeter 01. Furthermore, with the assistance of the laser detector 20 and the alignment fixture 10, the alignment accuracy between the colorimeter and the detection position is improved, thereby enhancing the accuracy of the measurement.

[0019] It is understood that the above embodiments are merely illustrative examples of aligning the first geometric center line of the first interface 110 with the principal optical axis a of the probe 100, the second geometric center line of the second interface 120 with the laser beam b of the laser detector 20, and the first geometric center line of the first interface 110 aligning with the second geometric center line of the second interface 120 to make the laser beam b emitted by the laser detector 20 coincide with the principal optical axis a of the probe 100. However, this is not a limitation. In other embodiments, the laser beam b emitted by the laser detector 20 can also be aligned with the principal optical axis a of the probe 100 in other ways. This utility model does not limit this.

[0020] It should be noted that, Figure 2 This is a schematic diagram of an alignment process provided by an embodiment of this utility model. See also: Figure 1 and Figure 2Ideally, the laser beam b emitted by the laser detector 20 coincides with the main optical axis a of the probe 100. However, in the actual manufacturing process of the alignment fixture 10, due to processing errors, there will be an error of 0.02 mm between the main optical axis a of the probe 100 and the laser beam emitted by the laser detector 20 after installation. That is, the distance between the center of the probe 100 and the center of the laser detector 20 is 0.02 mm. Furthermore, there are certain errors in the actual alignment process. For example, suppose the designated area AA of the detection position is a white circular pattern with a diameter of 0.5 mm, and the other areas are black. After connecting the first interface 110 to the probe 100 and the second interface 120 to the laser detector 20, the laser detector 20 is turned on, and the light spot (0.2 mm) formed by the laser detector 20 at the detection position is moved to the designated area AA to complete the alignment of the laser detector with the detection position. In this process, the diameter of the white circular pattern is 0.5 mm, and the diameter of the light spot is 0.2 mm. The positioning accuracy is (0.5-0.2) / 2 = 0.15 mm. Combining the previous positioning error of 0.02 mm, the final positioning accuracy error of the alignment device in this application is 0.17 mm. In contrast, the error of visual positioning in the prior art is generally greater than 2 mm. Therefore, the solution of this application can greatly improve the alignment accuracy, thereby improving the accuracy of the colorimeter 01 measurement.

[0021] It should also be noted that the connection between the second interface 120 and the laser detector 20 can be a fixed connection or a detachable connection. This embodiment of the present invention does not limit this, and those skilled in the art can set it as needed.

[0022] In summary, this embodiment of the invention uses an alignment fixture 10 to make the laser beam b emitted by the laser detector 20 coincide with the principal optical axis a of the probe 100. When aligning the colorimeter 01 with the detection position, the laser detector 20 is first aligned with the detection position. When the laser beam b emitted by the laser detector 20 illuminates the designated area of ​​the detection position, it indicates that the laser detector 20 is aligned with the detection position. Since the laser beam b emitted by the laser detector 20 coincides with the principal optical axis a of the probe 100, the principal optical axis a of the probe 100 is also aligned with the designated area of ​​the detection position. This eliminates the need for an alignment device, and the colorimeter 01 measures the chromaticity and / or brightness of the detection position, improving alignment accuracy and thus measurement accuracy.

[0023] Optionally, based on the above embodiments, Figure 3 This is a structural schematic diagram of an alignment device provided in an embodiment of this utility model. For example... Figure 3 As shown, the alignment fixture 10 also includes an inner diameter adjustment device 30, which is used to adjust the inner diameter of the first interface 110 and / or the second interface 120.

[0024] Specifically, the alignment fixture 10 also includes an inner diameter adjustment device 30 disposed outside the first interface 110 and / or the second interface 120. The inner diameter adjustment device 30 is used to adjust the inner diameter of the first interface 110 so that the inner diameter of the first interface 110 is the same size as the outermost part of the probe 100, thereby fixing part of the probe 100 inside the first interface 110. And / or the inner diameter adjustment device 30 is used to adjust the inner diameter of the second interface 120 so that the inner diameter of the second interface 120 is the same size as the non-light-emitting side of the laser detector 20, thereby facilitating the fixing of part of the laser detector 20 inside the second interface 120. In this way, by fixing the probe 100 inside the first interface 110 and fixing part of the laser detector 20 inside the second interface 120, and with the second interface 120 located at the center of the first interface 110, the main optical axis of the probe 100 is ensured to coincide with the laser beam emitted by the laser detector 20, thereby improving the alignment accuracy of the subsequent colorimeter 01 with the detection position.

[0025] Optionally, based on the above embodiments, Figure 4 This is a simplified structural diagram of another alignment device provided in this embodiment of the utility model, as shown below. Figure 4 As shown, the inner diameter adjustment device 30 includes at least one first spiral clamping device 310, which penetrates the outer wall of the first interface 110 and can be screwed in or out along the radial direction of the first interface 110 to adjust the distance between the first spiral clamping device 310 and the probe 100; and / or, the inner diameter adjustment device 30 includes at least one second spiral clamping device 320, which penetrates the outer wall of the second interface 120 and can be screwed in or out along the radial direction of the second interface 120 to adjust the distance between the second spiral clamping device 320 and the laser detector 20.

[0026] For example, such as Figure 4 In the illustrated embodiments, the example provided is merely illustrative of a first spiral clamping device 310 on the first interface 110 and a second spiral clamping device 320 on the second interface 120. This is not a limitation; in other embodiments, the first spiral clamping device 310 may be provided only on the first interface 110, or the second spiral clamping device 320 may be provided only on the second interface 120. Those skilled in the art can configure these as needed. For details, please refer to [link to previous text]. Figure 4A first spiral clamping device 310 can be provided on the first interface 110. The first spiral clamping device 310 penetrates the outer wall of the first interface 110 and has threads inside the outer wall of the first interface 110. The first spiral clamping device 310 can be screwed in or out in the radial direction of the first interface 110, and the distance between the first spiral clamping device 310 and the probe 100 can be adjusted, thereby adjusting the accommodating inner diameter of the first interface 110 (the actual inner diameter of the first interface 110 will not change). When the first spiral clamping device 310 and the probe 100 have a set distance, the probe 100 is not fixed in the first interface 110. When the first spiral clamping device contacts the probe 100, the probe 100 is fixed in the first interface 110. In this way, the first interface 110 and the probe 100 are fixed by the first spiral clamping device 310, thereby ensuring that the fixing and disassembly methods of the first interface 110 are simple. Similarly, at least one second spiral clamping device 320 is provided on the second interface 120. The second spiral clamping device 320 penetrates the outer wall of the second interface 120 and has threads inside the outer wall of the second interface 120. The second spiral clamping device 320 can be screwed in or out in the radial direction of the second interface 120, thereby adjusting the distance between the second spiral clamping device 320 and the laser detector 20, and thus adjusting the accommodating inner diameter of the second interface 120 (the actual inner diameter of the second interface 120 will not change). When the second spiral clamping device 320 and the laser detector 20 have a set distance, the laser detector 20 is not fixed in the second interface 120. When the second spiral clamping device 320 contacts the laser detector 20, the laser detector 20 is fixed in the second interface 120. In this way, the second spiral clamping device 320 is used to keep the second interface 120 and the laser detector 20 in a simple fixing and disassembly manner.

[0027] It is understandable that, such as Figure 4 In the embodiment shown, the first spiral clamping device 310 and the second spiral clamping device 320 are located on the same side. At this time, the position of the probe 100 inside the first interface 110 is the same as the position of the laser detector 20 inside the second interface 120, so that the laser beam emitted by the laser detector 20 can be approximately coincident with the main optical axis of the probe 100.

[0028] In yet another embodiment, Figure 5 This is a simplified structural diagram of another alignment device provided in an embodiment of this utility model. See also... Figure 5 The inner diameter adjustment device 30 includes two first spiral clamping devices 310, which are symmetrically arranged along the center of the first interface 110; and / or, the inner diameter adjustment device 30 includes two second spiral clamping devices 320, which are symmetrically arranged along the center of the second interface 120.

[0029] For example, such as Figure 5 In the illustrated embodiment, the inner diameter adjustment device 30 includes two first spiral clamping devices 310 and two second spiral clamping devices 320. The two first spiral clamping devices 310 are symmetrically arranged around the center of the first interface 110. During adjustment, both symmetrical first spiral clamping devices 310 can be adjusted simultaneously to ensure they are adjusted by the same distance. Thus, when both first spiral clamping devices 310 are in contact with the probe 100, it indicates that the probe 100 is fixed at the exact center of the first interface 110. Similarly, the two second spiral clamping devices 320 are symmetrically arranged around the center of the second interface 120. During adjustment, both symmetrical second spiral clamping devices 320 can be adjusted simultaneously to ensure they are adjusted by the same distance. Thus, when both second spiral clamping devices 320 are in contact with the laser detector 20, it indicates that the laser detector 20 is fixed at the exact center of the second interface 120. Furthermore, since the first geometric center line of the first interface 110 coincides with the second geometric center line of the second interface 120, it can be ensured that the laser beam emitted by the laser detector 20 coincides with the main optical axis of the probe 100, thereby improving the alignment accuracy between the colorimeter 01 and the detection position during subsequent alignment.

[0030] It should be noted that, Figure 5 The description is exemplified only by the inner diameter adjustment device 30 including two first spiral clamping devices 310 and two second spiral clamping devices 320, but it is not a limitation. In other embodiments, the inner diameter adjustment device 30 may be configured to include only two first spiral clamping devices 310 or only two second spiral clamping devices 320. Those skilled in the art can configure it as needed.

[0031] Optionally, based on the above embodiments, Figure 6 This is a simplified structural diagram of another alignment device provided in an embodiment of this utility model. See also... Figure 6 The first interface 110 includes a first surface S1 and a second surface S2 disposed opposite to each other. The gap between the first surface S1 and the second surface S2 extends through the side wall of the first interface 110. The inner diameter adjustment device 30 includes a first adjusting screw 301 disposed on the first surface S1 and the second surface S2 and rotatable in the radial direction of the first interface 110 to adjust the inner diameter of the first interface 110. And / or, the second interface 120 includes a third surface S3 and a fourth surface S4 disposed opposite to each other. The gap between the third surface S3 and the fourth surface S4 extends through the side wall of the second interface 120. The inner diameter adjustment device 30 includes a second adjusting screw 302 disposed on the third surface S3 and the fourth surface S4 and rotatable in the radial direction of the second interface 120 to adjust the inner diameter of the second interface 120.

[0032] For example, such as Figure 6 In the illustrated embodiment, the inner diameter adjustment device 30 includes a first adjusting screw 301 and a second adjusting screw 302 as an example for explanation, but this is not a limitation. In other embodiments, the inner diameter adjustment device 30 may include only the first adjusting screw 301 or only the second adjusting screw 302. Those skilled in the art can configure it as needed. Specifically, the outer wall of the first interface 110 has a gap that penetrates the first interface 110, thereby forming a first surface S1 and a second surface S2 on the outer wall of the first interface 110. The first surface S1 and the second surface S2 are arranged opposite to each other. The first adjusting screw 301 penetrates the first surface S1 and the second surface S2, and a nut is provided on one of them. When the first adjusting screw 301 rotates in the radial direction of the first interface 110, the distance between the first surface S1 and the second surface S2 can be adjusted, thereby adjusting the inner diameter of the first interface 110 so that the inner diameter of the first interface 110 is the same as the size of the probe 100. Thus, when the probe 100 is fixed inside the first interface 110, the probe 100 is located at the exact center of the first interface 110. Similarly, the outer wall of the second interface 120 has a gap that penetrates the second interface 120, thus forming a third surface S3 and a fourth surface S4 on the outer wall of the second interface 120. The third surface S3 and the fourth surface S4 are arranged opposite each other. The second adjusting screw 302 penetrates the third surface S3 and the fourth surface S4, and a nut is provided on one of them. Thus, when the second adjusting screw 302 rotates in the radial direction of the second interface 120, the distance between the third surface S3 and the fourth surface S4 can be adjusted, thereby adjusting the inner diameter of the second interface 120 so that the inner diameter of the second interface 120 is the same as the size of the laser detector 20. In this way, when the laser detector 20 is fixed in the second interface 120, the laser detector 20 is located at the exact center of the second interface 120. Based on the above, since the second interface 120 is located at the exact center of the first interface 110, it can be ensured that the main optical axis of the probe 100 coincides with the laser beam emitted by the laser detector 20, thereby improving the alignment accuracy of the subsequent colorimeter 01 with the detection position.

[0033] Optionally, based on the above embodiments, see also... Figure 3The alignment fixture 10 also includes a connecting portion 130, which connects the first interface 110 and the second interface 120. Specifically, the shapes of the two ends of the connecting portion 130 are the same as those of the first interface 110 and the second interface 120, respectively, and the geometric center line of the connecting portion 130 coincides with the geometric center line of the first interface 110 and the geometric center line of the second interface 120. This ensures that the geometric center line of the first interface 110 coincides with the geometric center line of the second interface 120, thereby ensuring that the laser beam emitted by the laser detector 20 can be adjusted to coincide with the principal optical axis of the probe 100 through the first interface 110 and the second interface 120.

[0034] In yet another embodiment, see also... Figure 3 The connecting part 130 includes a retractable connecting part, which is used to adjust the distance between the first interface 110 and the second interface 120. Specifically, the retractable connecting part can extend and retract along the axial direction of the first interface 110 or the second interface 120, thereby adjusting the distance between the first interface 110 and the second interface 120. In other words, during the alignment process, the vertical distance between the laser detector 20 in the second interface 120 and the detection position can be adjusted, so that the laser detector 20 forms a stable light spot at the detection position, which facilitates subsequent alignment of the light spot with the designated area of ​​the detection position.

[0035] Optionally, in yet another embodiment, see also [link to previous document]. Figure 1 The inner diameter of the first interface 110 is fixed and is the same as the outer diameter of the probe 100. The inner diameter of the second interface 120 is fixed and is the same as the outer diameter of the laser detector 20. Specifically, when preparing the alignment fixture 10, the shape and size of the first interface 110 are prepared according to the outer diameter of the probe 100, and the shape and size of the second interface 120 are prepared according to the outer diameter of the laser detector 20, so that the probe 100 can fit perfectly onto the first interface 110 and the laser detector 20 can fit perfectly onto the second interface 120. In this way, there is no need for an inner diameter adjustment device to adjust the inner diameter of the first interface 110 and / or the second interface 120, thus simplifying the fixing methods of the probe 100 and the first interface 110, and the laser detector 20 and the second interface 120.

[0036] It should be noted that, based on the above embodiments, the first interface 110 can be fixedly connected to the probe 100 through the first buckle, and the second interface 120 can be fixedly connected to the laser detector 20 through the second buckle. In this way, the buckle method can further ensure the stability of the fixation, and can more easily realize the disassembly of the laser detector 20 and / or the alignment fixture 10.

[0037] In one embodiment, the laser detector 20 can be a laser pointer. The laser pointer has the characteristics of precise pointing and ultra-high brightness ratio, so it can form a stable light spot at the detection position and improve the alignment accuracy between the laser detector 20 and the detection position. In other embodiments, the laser detector 20 can also be other devices. This utility model does not limit this, and those skilled in the art can set it as needed.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention.
