Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to an OLED display module testing device. Background Technology

[0002] An OLED display module is a display component based on organic electroluminescent diode (OLED) technology. It consists of an OLED display screen, a PCB, and a metal frame. Its core lies in a very thin organic material coating and a glass substrate. When current passes through it, the organic material emits light, achieving self-emissive display without the need for a backlight. Therefore, it has advantages such as high contrast, wide viewing angle, ultra-thinness, low power consumption, and fast response.

[0003] OLED display modules require testing equipment during production. Existing testing equipment typically uses a spectrometer to test the display module. However, the spectrometer cannot clamp and support the display module during testing. The display module is prone to positional displacement due to slight external forces or equipment vibrations during testing. This causes the position of the light signal collected by the spectrometer to change, resulting in inaccurate spectral information such as wavelength and intensity. Consequently, the evaluation of the display module's display performance is biased and cannot truly reflect the module's quality. Utility Model Content

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1: Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an OLED display module testing device, including a fixing frame 1. A spectrometer 2 and an optical probe body 3 are respectively installed on the top of the inner cavity of the fixing frame 1. A fixing seat 4 is fixed at the bottom of the inner cavity of the fixing frame 1. A support seat 5 is provided on the top of the fixing seat 4. A support frame 6 is fixed on the top of the support seat 5. A clamping component 7 for clamping the display module is provided inside the support frame 6. A first clamping plate 8 for cooperating with the clamping component 7 is fixed on one side of the support frame 6. A support plate 9 is slidably connected to the inner wall of the support frame 6. A protective pad 10 is provided on the top of the support plate 9.

[0022] The spectrometer 2 in this application works on the same principle as the detection body in application number 202421341380.0. It is used to perform spectral analysis on the light emitted by the OLED display module to obtain spectral information such as wavelength and intensity of the light in order to evaluate the display performance of the display module. This is prior art and will not be described in detail here. The optical probe body 3 in this application works on the same principle as an optical probe in application number 202021525628.0. It is responsible for collecting the light signal emitted by the display module and transmitting it to the spectrometer 2 for analysis. The clamping component 7 fixes the display module on the support frame 6 and works in conjunction with the first clamping plate 8 to improve the fixing and clamping effect of the display module. The support plate 9 supports the display module and improves the clamping effect of the display module.

[0023] The clamping assembly 7 includes a bidirectional screw 71 rotatably connected to the inner wall of the support frame 6. The outer side of the bidirectional screw 71 is threaded with two sets of symmetrically arranged threaded blocks 72. The inner wall of the threaded blocks 72 is rotatably connected to a second clamping plate 73 for clamping the display module via a universal ball joint.

[0024] The rotation of the bidirectional screw 71 drives the two sets of threaded blocks 72 to move relative to or towards each other. The movement of the threaded blocks 72 drives the movement of the second clamping plate 73, thereby clamping or releasing the display module. The universal ball joint structure allows the second clamping plate 73 to rotate freely within a certain angle range. When clamping a display module with a curved or irregular shape, the second clamping plate 73 can adjust its angle to fit tightly against the module surface, improving the stability and fit of the clamping.

[0025] The second clamping plate 73 is fixed to the outer side by a mounting bracket 21 by bolts. A clamping head 22 is fixed to one side of the mounting bracket 21. A vacuum adsorption tube 23 is fixed to the inner wall of the support plate 9. One end of the vacuum adsorption tube 23 extends through to the outer side of the support plate 9 and is connected to a connector 24.

[0026] The mounting bracket 21 is fixed with bolts to install the clamping head 22, and the mounting bracket 21 is easy to disassemble, making it convenient to replace clamping heads 22 of different sizes and shapes in the future, further enhancing the adaptability and flexibility of clamping. The outer side of the connector 24 is connected to a valve. By connecting the connector 24 to a vacuum pump, one end of the vacuum adsorption tube 23 generates an adsorption force on the display module placed on the support plate 9, further enhancing the stability of the module, which is especially suitable for some thin or smooth display modules.

[0027] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0028] Specifically, the inner wall of the support frame 6 is rotatably connected to a first rotating wheel 11 that drives the bidirectional screw 71 to rotate, and the axis of the first rotating wheel 11 is fixed to the outer side of the bidirectional screw 71.

[0029] By rotating the first rotating wheel 11, the bidirectional screw 71 can be driven to rotate, thereby realizing the operation of the clamping assembly 7 and making it convenient for the user to control the movement of the second clamping plate 73.

[0030] Specifically, a guide frame 12 is fixed to the top of the support frame 6, a guide plate 13 is fixed to one side of the threaded block 72, and the outer side of the guide plate 13 is slidably connected to the inner wall of the guide frame 12.

[0031] The movement of the second clamping plate 73 will cause the guide plate 13 to slide inside the guide frame 12, which can ensure that the second clamping plate 73 maintains linear motion during the movement, thereby improving the accuracy and stability of clamping.

[0032] Specifically, the inner wall of the support frame 6 is rotatably connected to a threaded rod 14, and the top of the threaded rod 14 is fixedly connected to the bottom of the support plate 9. The inner wall of the support frame 6 is rotatably connected to a second rotating wheel 15, and the axis of the second rotating wheel 15 is threadedly connected to the outer side of the threaded rod 14.

[0033] By rotating the second rotating wheel 15, the threaded rod 14 is driven to move up and down. The threaded rod 14 can drive the support plate 9 to move up and down, thereby supporting the display module and supporting the display module inside the second clamping plate 73, improving the stability of the support and clamping of the display module.

[0034] Specifically, a guide rod 16 is fixed to the bottom of the support plate 9, and the outer side of the guide rod 16 is slidably connected to the inner wall of the support frame 6.

[0035] The up-and-down movement of the support plate 9 will cause the guide rod 16 to slide inside the support frame 6, preventing the support plate 9 from deflecting during the up-and-down movement, ensuring that the support plate 9 always maintains vertical movement, and improving the stability of the movement of the support plate 9.

[0036] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, an electric push rod 17 is installed on the inner wall of the fixed base 4, and the top rod of the electric push rod 17 is fixed to the bottom of the support base 5. A slide rod 18 is fixed to the bottom of the support base 5, and a limit block 19 is fixed to the outer side of the fixed base 4. The outer side of the slide rod 18 is slidably connected to the inner wall of the limit block 19.

[0038] Activating the electric push rod 17 can push the support base 5 to move up and down, which can drive the support base 5 and the components above it to make precise vertical adjustments, thereby facilitating the adjustment of the detection height of the display module. The movement of the support base 5 will cause the slide rod 18 to slide inside the limit block 19, improving the stability of the movement of the support base 5.

[0039] Specifically, a cooling fan 20 is fixed to the inner wall of the mounting bracket 1.

[0040] The cooling fan 20 accelerates airflow, carrying away heat and preventing the display module from overheating and affecting test results or causing damage.

[0041] In use, the light signal collected by the optical probe body 3 is transmitted to the spectrum analyzer 2. The spectrum analyzer 2 can perform spectral analysis on the light to obtain spectral information such as wavelength and intensity, thereby evaluating the display performance of the display module. The display module is placed on the support plate 9, and the protective pad 10 prevents damage to the module. By connecting the connector 24 to the vacuum pump, one end of the vacuum adsorption tube 23 generates an adsorption force on the display module placed on the support plate 9, further enhancing the stability of the module, which is especially suitable for some thin or smooth display modules. Rotating the first rotating wheel 11 drives the bidirectional screw 71 to rotate. The rotation of the bidirectional screw 71 causes the two sets of threaded blocks 72 to move relative to or towards each other, thereby driving the second clamping plate 73 and the clamping head 22 to move. The clamping head 22 cooperates with the first clamping plate 8 to clamp or release the display module. The mounting bracket 21 is fixed by bolts, thereby installing the clamping head 22 and facilitating the mounting bracket 21. Disassembly facilitates the subsequent replacement of clamping heads 22 of different sizes and shapes, further enhancing the adaptability and flexibility of clamping. The movement of the second clamping plate 73 drives the guide plate 13 to slide within the guide frame 12, ensuring the linear movement of the second clamping plate 73, improving clamping accuracy and stability. Furthermore, the universal ball joint structure allows the second clamping plate 73 to rotate freely within a certain angle range. When clamping display modules with curved or irregular shapes, the second clamping plate 73 can adjust its angle to closely fit the module surface, improving clamping stability and fit. Rotating the second rotating wheel 15 drives the threaded rod 14 to move up and down, which in turn drives the support plate 9 to move up and down, supporting the display module and stabilizing it in a suitable position. The movement of the support plate 9 drives the guide rod 16 to slide within the support frame 6, preventing the support plate 9 from deflecting and ensuring vertical movement. In addition, the electric push rod 17 can push the support base 5 up and down, driving the upper components to precisely lift and lower, adjusting the detection height of the display module.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
