Description

Technical Field

[0001] This disclosure relates to the field of color calibration and testing equipment technology, and more particularly to a stand-alone screen color testing device. Background Technology

[0002] The color reproduction accuracy of a display screen is represented by the ΔE value. The smaller the ΔE value, the higher the color reproduction and the better the user experience. Taking laptops as an example, in current technology, the ΔE value of laptop screens calibrated by suppliers is offset after the entire machine is assembled. When calibrating the entire machine, the ΔE value can only meet the requirement of approximately ΔE 2.0, which cannot achieve the industry-leading calibration effect of ΔE ≤ 1.0.

[0003] Therefore, there is an urgent need in the market for a screen color testing device that can perform whole-machine color calibration and meet the requirement of a calibration effect ΔE value ≤ 1.0, in order to solve the problem of poor whole-machine screen color calibration effect and difficulty in guaranteeing screen color reproduction in existing technologies. Summary of the Invention

[0004] This disclosure provides a standalone screen color testing device to address the problem in the prior art where the overall color calibration effect of laptop screens is poor and it is difficult to guarantee screen color reproduction.

[0006] The device body has a platform for placing the machine to be tested, and a darkroom that covers the platform.

[0007] The testing mechanism includes a test probe disposed in the dark chamber and a drive assembly that is drively connected to the test probe.

[0008] The angle correction mechanism is disposed in the platform and is used to correct and adjust the opening and closing angle of the screen of the whole machine;

[0009] The driving component can drive the test probe to reciprocate in the up-down and left-right directions in the dark chamber;

[0010] The platform can drive the entire device under test to move back and forth along the front and back direction of the darkroom.

[0011] In one possible implementation, the angle correction mechanism includes an abutment joint and a translational drive mechanism;

[0012] The abutment is configured as a cylindrical rolling body capable of rolling against the back side of the screen of the whole machine;

[0013] The translational drive mechanism can drive the abutment to move back and forth in the front-back direction toward or away from the back side of the screen.

[0014] In one possible implementation, the angle correction mechanism further includes an angle detector;

[0015] The angle detector is installed on the mounting plate facing the back of the screen and is used to detect the angle formed between the mounting plate and the back of the screen.

[0016] In one embodiment, the testing mechanism further includes a ranging element that is flush with the testing probe along the front-to-back direction;

[0017] The ranging device can move synchronously with the test probe and measure the real-time distance between the test probe and the screen of the whole machine.

[0018] In one embodiment, the probe end of the test probe is provided with an elastic light-shielding sleeve;

[0019] The front end of the ranging device is provided with an elastic buffer pad.

[0020] In one possible implementation, the drive assembly includes a lifting frame and a sliding frame;

[0021] The lifting frame is arranged in the dark chamber along the vertical direction and has a first linear motor for driving the test probe to move along the vertical direction;

[0022] The sliding frame is arranged in the dark chamber along the left-right direction and has a second linear motor for driving the test probe to move in the left-right direction.

[0023] In one embodiment, the platform surface of the platform is further provided with a platform rail extending in the front-rear direction.

[0024] Furthermore, the platform rail is equipped with a tray holder for placing the entire machine to be tested.

[0025] In one embodiment, the carrier plate is provided with a clamping mechanism for clamping the machine under test and a drive motor for driving the machine under test to reciprocate along the carrier plate rail.

[0026] In one embodiment, the clamping mechanism includes a clamping opening and closing cylinder for clamping the machine under test in the front-back direction, and a centering clamping device for clamping the machine under test in the left-right direction.

[0027] In one possible implementation, the darkroom is provided with an opening and closing door corresponding to the platform;

[0028] The device under test enters the darkroom, and the door closes accordingly to block the light from the platform.

[0029] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0030] In practical use, the screen color stand-alone testing device provided in this embodiment first opens the laptop to a preset angle. Then, the laptop body is clamped and placed on the platform in the device body. At this time, the angle correction mechanism in the platform can detect whether the screen opening angle meets the error value of the preset angle. If it does not meet the error value, it corrects and adjusts the opening angle of the screen to meet the optimal requirements of the testing mechanism for color calibration.

[0042] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0043] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0044] Combination Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the present disclosure provides a screen color single-device testing device, which includes a device body 1, a testing mechanism 2, and an angle correction mechanism 3. The device body 1 has a platform 11 for placing the device under test and a dark chamber 12 covering the platform 11. The testing mechanism 2 includes a test probe 21 disposed in the dark chamber 12 and a drive assembly 22 that is pulsatorically connected to the test probe 21. The angle correction mechanism 3 is disposed in the platform 11 and is used to correct and adjust the opening and closing angle of the device screen. The drive assembly 22 can drive the test probe 21 to reciprocate in the up-down and left-right directions of the dark chamber 12. The platform 11 can drive the device under test to reciprocate in the front-back direction of the dark chamber 12.

[0045] This standalone screen color testing device can be applied to specific scenarios, including but not limited to color calibration of laptop screens and foldable phone screens. The following explanation will use laptop screen color calibration as an example.

[0046] In practical use, the screen color stand-alone testing device first opens the laptop to be tested to a preset angle (for example, the screen can be opened to a 90° angle with the body). Then, the body is clamped and placed on the stage 11 in the device body 1. At this time, the angle correction mechanism 3 in the stage 11 can detect whether the screen opening angle meets the error value of the preset angle. If it does not meet the error value, it will correct and adjust the opening angle of the screen to ensure that the opening angle of the screen under test meets the optimal requirements of the testing mechanism 2 for color calibration.

[0047] After the screen angle is corrected and adjusted, the darkroom 12 covers the stage 11 with a light shield. The test probe 21 in the test mechanism 2 can then move up and down and left and right under the drive of the drive component 22, and the stage 11 moves back and forth in the front and back direction until the test probe 21 is completely perpendicular to the screen under test in the three-dimensional coordinate system. Then the color calibration module in the test probe 21 can collect the screen color and perform color ΔE value verification.

[0048] In summary, the screen color stand-alone testing device provided in this embodiment can ensure that the opening and closing angle of the screen under test meets the error value of the preset angle through the angle correction mechanism 3; and can ensure that the test probe 21 can be completely and safely attached to the screen under test in the three-dimensional spatial coordinate system by moving the drive component 22 and the stage 11 in the testing mechanism 2, thereby ensuring the accuracy of the screen color acquisition and achieving excellent verification results with a color ΔE value ≤ 1.0.

[0049] In one embodiment, the angle correction mechanism 3 includes an abutment 31 and a translational drive mechanism 32; the abutment 31 is configured as a cylindrical rolling body capable of rolling against the back side of the screen; the translational drive mechanism 32 is capable of driving the abutment 31 to move back and forth in the front-back direction toward or away from the back side of the screen.

[0050] Specifically, in combination Figure 3 and Figure 4 In further detail, the angle correction mechanism 3 is specifically configured to include an abutment 31 and a translational drive mechanism 32. The translational drive mechanism 32 can drive the abutment 31 to move back and forth in the front-back direction toward or away from the back side of the screen. In this way, the abutment 31 can correspondingly abut against the screen and realize the function of correcting and adjusting the opening angle of the screen.

[0051] Furthermore, the abutment 31 is configured as a cylindrical rolling body that can roll against the back of the screen. When the screen opening angle is greater than 90°, the abutment 31 can be driven by the translational drive mechanism 32 to move towards the back of the screen and press against it, and drive the abutment 31 to roll along the back of the screen to prevent bumps and scratches to the back of the screen when pressing against it. When the screen opening angle is less than 90°, the test probe 21 can be completely pressed against the screen under the drive component 22. At this time, the opening angle of the screen will gradually increase, and when it reaches 90°, the back of the screen will abut against the abutment 31, thereby limiting the opening angle of the screen to 90°. The abutment 31 and the test probe 21 jointly limit the screen on the front and back sides to prevent the screen from being opened excessively.

[0052] In one embodiment, the angle correction mechanism 3 further includes an angle detector 33; the angle detector 33 is mounted on the mounting plate facing the back of the screen and is used to detect the angle formed between the mounting plate and the back of the screen.

[0053] Specifically, in combination Figure 4 and Figure 6 In further detail, the aforementioned angle detector 33 can be specifically, but not limited to, an angle sensor. Furthermore, two mounting plates are set at specific flush intervals. Each mounting plate has one angle detector 33 set on the back side of the screen. When the device under test is placed and fixed in the stage 11, if the screen is not fully opened to 90°, a wedge-shaped gap can be formed between the back side of the screen and the mounting plate. This allows the angle detector 33 to determine the actual angle between the two by detecting the size of the gap.

[0054] Furthermore, if the angle detector 33 detects that the screen angle is opened to more than 90° and exceeds the error, the angle detector 33 can adjust the angle correction mechanism 3 according to its own detection results to ensure that the opening angle of the screen under test always meets the optimal requirements of the test mechanism 2 for color calibration.

[0055] In one embodiment, the testing mechanism 2 further includes a distance measuring element that is flush with the test probe 21 along the front-back direction; the distance measuring element can move synchronously with the test probe 21 and measure the real-time distance between the test probe and the screen of the whole machine.

[0056] A distance measuring device is set in the testing mechanism 2, which is flush with the test probe 21 along the front-to-back direction. The distance measuring device can move synchronously with the test probe 21 and measure the real-time distance between the test probe 21 and the screen at all times. This can avoid the problem of the test probe 21 hitting, bumping and scratching the screen during the movement.

[0057] Furthermore, in order to obtain the actual height of the test probe 21 in real time, an infrared ranging sensor can be set downwards in the test probe 21 to understand the actual lifting height of the test probe 21 in real time.

[0058] In one embodiment, the detection end of the test probe 21 is provided with an elastic light-shielding sleeve 211; the front end of the ranging device is provided with an elastic buffer pad.

[0059] Specifically, in combination Figure 4 In further detail, the probe 21 is equipped with an elastic light-shielding sleeve 211 at its detection end. The elastic light-shielding sleeve 211 can be specifically, but is not limited to, a rubber sleeve with a central opening. When the probe 21 is completely perpendicular and in close contact with the screen under test, the elastic light-shielding sleeve 211 can completely cover and isolate the outer peripheral wall of the probe 21, so that only the color light emitted by the screen can be collected by the probe 21, avoiding the influence of ambient light on the screen color calibration. Moreover, the elastic light-shielding sleeve 211 can also buffer the force when the probe 21 contacts the screen under test, further preventing accidental collisions when the two come into contact.

[0060] In addition, an elastic buffer pad is provided at the front end of the ranging device to prevent the screen from being bumped and worn when the ranging device moves synchronously with the test probe 21. The elastic buffer pad can also be made of rubber or EVA plastic.

[0061] In one embodiment, the drive assembly 22 includes a lifting frame 221 and a sliding frame 222; the lifting frame 221 is disposed in the dark chamber 12 in the vertical direction and has a first linear motor for driving the test probe 21 to move in the vertical direction; the sliding frame 222 is disposed in the dark chamber 12 in the horizontal direction and has a second linear motor for driving the test probe 21 to move in the horizontal direction.

[0062] Specifically, in combination Figure 3 In further detail, the drive assembly 22 is specifically configured as a lifting frame 221 extending vertically along the dark chamber 12, and the lifting frame 221 has a first linear motor to drive the test probe 21 to reciprocate vertically; the sliding frame 222 is set horizontally along the dark chamber 12, and the test probe 21 is driven to reciprocate horizontally by a second linear motor. In this way, the drive assembly 22 can stably drive the test probe 21 to move precisely and controllably vertically and horizontally within the dark chamber 12.

[0063] The specific configuration of the aforementioned drive component 22 has the advantages of simple structure and precise control over the up-down and front-back positions of the test probe 21.

[0064] In one embodiment, the platform 11 is further provided with a platform rail 111 extending in the front-to-back direction; and the platform rail 111 is provided with a tray seat 4 for placing the whole machine to be tested.

[0065] Specifically, in combination Figure 3 and Figure 4 In further detail, a stage rail 111 extending along the front-back direction of the darkroom 12 is provided on the platform of the stage 11, and a tray holder 4 for placing the device under test is provided in the stage rail 111. Thus, the tray holder 4 can move back and forth along the extension direction of the stage rail 111, thereby correspondingly moving the screen of the device under test in the tray holder 4 toward or away from the test probe 21 in the front-back direction. The tray holder 4 and the drive assembly 22 cooperate to realize the movement of the test probe 21 in the three-dimensional coordinate system corresponding to the movement of the screen of the device under test.

[0066] In one embodiment, the tray base 4 is provided with a clamping mechanism for clamping the machine under test and a drive motor for driving the machine under test to reciprocate along the carrier rail 111.

[0067] Specifically, in combination Figure 4 and Figure 5 In further detail, the clamping mechanism in the tray holder 4 can be used to clamp and fix the device under test in the tray holder 4, and the drive motor in the tray holder 4 can achieve reciprocating linear movement along the platform rail 111 through transmission mechanisms such as "screw and nut" and "gear and rack".

[0068] In one embodiment, the clamping mechanism includes a clamping opening and closing cylinder 41 for clamping the machine under test in the front-back direction, and a centering clamping device 42 for clamping the machine under test in the left-right direction.

[0069] Specifically, in combination Figure 5 In further detail, the clamping cylinder 41 can clamp the device under test in the front-to-back direction by moving closer together, while the centering clamping device 42 can clamp the device under test in the left-to-right direction. When placing the device under test in the tray 4, the centering clamping device 42 first centers and limits the device under test in the left-to-right direction, and then the clamping cylinder 41 is controlled to finally fix the device under test in the left-to-right direction, thereby ensuring the firmness and accurate positioning of the device under test in the tray 4.

[0070] Moreover, the aforementioned centering clamping device 42 can be specifically configured as two L-shaped clamps facing each other, and the two are connected to each other by elastic members of equal length and equal elastic coefficient. In this way, the two L-shaped clamps can center and clamp the whole machine under test under the action of equal elastic force of the elastic members.

[0071] In one embodiment, an opening and closing door 121 corresponding to the platform 11 is provided in the dark chamber 12; the device to be tested enters the dark chamber 12 and the opening and closing door 121 closes accordingly, so as to block the light and seal the platform 11 through the dark chamber 12.

[0072] Specifically, in combination Figure 1 and Figure 2 In further detail, the aforementioned opening and closing door 121 can be specifically, but not limited to, being installed in the platform 11 by means of vertical lifting. In this way, when the device under test moves back and forth along the platform rail 111 with the tray 4 and enters the dark chamber 12, the opening and closing door 121 can be lowered and closed accordingly, so that the dark chamber 12 can block the light and seal the platform 11, fully isolating the influence of external ambient light on the light transmission of the test probe 21.

[0073] Furthermore, a QR code scanner can be set up in the darkroom 12 to scan and read the model type of the device under test, and to match the color calibration values ​​and color brightness calibration by burning the corresponding color calibration values ​​to the computer through the burning device according to the model type.

[0074] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0075] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
