Description

Technical Field

[0001] This utility model relates to the field of optical testing, and in particular to a screen aging test device. Background Technology

[0002] During product aging tests or troubleshooting in R&D, it is often necessary to observe the screen display status for extended periods to record any abnormal display conditions and durations, which typically requires a significant investment of time and effort.

[0003] Traditional solutions typically involve direct manual observation, requiring staff to visually inspect the screen for extended periods. This not only consumes manpower and resources but also increases the risk of misjudgments and omissions during long hours, significantly impacting employee health.

[0004] Therefore, the most common screen aging test device currently available uses a visual recognition scheme to replace manual observation. Specifically, the screen aging test device includes a camera and a processor. The processor is connected to the camera. The camera continuously captures images of the screen under test to obtain initial images. These initial images are then sent to the processor for image analysis and processing to obtain the screen test results.

[0005] However, existing screen aging test equipment requires the use of cameras for image acquisition, which is expensive and difficult to afford for large-scale testing environments in actual production. At the same time, due to the focal length limitation of the camera, the camera needs to maintain a certain distance from the screen under test in order to acquire a normal initial image, which occupies a large space. The large space occupied is also susceptible to environmental interference, leading to recognition errors. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a screen aging test device that can reduce space occupation and greatly reduce production costs.

[0010] The processor is connected to the color sensor through the detection box, receives color information and analyzes it to obtain the aging test results of the screen under test.

[0011] Compared with the prior art, the screen aging test device of this invention simplifies the internal structure and reduces the need for test space, thereby reducing production costs.

[0012] Furthermore, it also includes a microcontroller, which is disposed in the detection box. The microcontroller is connected to the color sensor and the processor, receives the color information from the color sensor and converts it into stored color data, and the processor receives the color data and analyzes it to obtain the aging test results of the screen under test.

[0013] Furthermore, the test box is equipped with a bus connector for CAN bus connection. The bus connector has a bus interface with the opening facing one side of the test box. A bus window is provided on this side, and the bus interface corresponds to the bus window. Multiple screen aging test devices are connected to their respective bus connectors via CAN bus, so that the processor can realize cascaded control of multiple screen aging test devices.

[0014] Furthermore, the detection box is also equipped with a data connector, which is connected to the processor and the microcontroller respectively, so as to realize data communication between the processor and the microcontroller.

[0015] Furthermore, the detection box has an opaque sealing strip around its hollowed-out surface, and the sealing strip is made of a soft material.

[0016] Furthermore, a fixing member is provided on the top surface of the test box, and the fixing member has a small hole. A rope or hook is passed through the small hole to attach the test box to the surface of the screen to be tested.

[0017] Furthermore, the sealing strip is made of an adhesive material to adhere the test box to the surface of the screen to be tested.

[0018] Furthermore, the detection box is also equipped with a power connector, which is electrically connected to the color sensor, the microcontroller and the data connector respectively, and supplies power to the color sensor, the microcontroller and the data connector.

[0024] Combination Figures 1 to 4 This utility model provides a screen aging test device, including a test box 10, a color sensor 20, a microcontroller 30 and a processor (not shown).

[0025] The test box 10 is set on the surface of the screen A to be tested. A fixing member 11 is provided on the top surface of the test box 10. The fixing member 11 has a small hole, through which a rope or hook can be passed to attach the test box 10 to the surface of the screen A to be tested. The bottom surface is a hollow plane, and the hollow bottom surface of the test box 10 is close to the screen A to be tested.

[0026] In one embodiment, the detection box 10 has an opaque sealing strip around its perforated surface to allow it to better adhere to the surface of the screen A under test, reducing the influence of ambient light. The sealing strip is also made of a soft material to prevent damage to the screen A. Specifically, the sealing strip can be made of an adhesive material to attach the detection box 10 to the surface of the screen A, thus saving the need for additional support using rope.

[0027] The color sensor 20 is disposed inside the detection box 10. It detects the screen A under test through the hollow surface of the detection box 10 to obtain the color information of the screen A under test. Preferably, there can be multiple color sensors 20, thereby increasing the distribution density of the color sensors 20 to improve the color recognition accuracy and precision of the screen A under test.

[0028] The microcontroller 30 is installed inside the detection box 10 and connected to the color sensor 20. It receives the color information detected by the color sensor 20 and converts it into stored color data.

[0029] The processor is connected to the microcontroller 30 through the detection box 10, receives the color data from the microcontroller 30 and analyzes it to obtain the aging test results of the screen A under test.

[0030] Specifically, a power connector 12 and a data connector 13 are provided on the bottom surface of the detection box 10. The power connector 12 has a power interface with its opening facing one side of the detection box 10. A power window is located on this side, and the power interface corresponds to the power window, through which power is supplied to the external environment. The power connector 12 is electrically connected to the color sensor 20, the microcontroller 30, and the data connector 13, respectively, supplying power to these components.

[0031] The data connector 13 has a data connection port, the opening of which faces one side of the detection box 10. A data connection window is located on this side, and the data connector corresponds to the data connection window, through which the data connector connects to the processor. The data connector 13 is electrically connected to the microcontroller 30, and the processor is connected to the microcontroller 30 via the data connector 13 of the detection box 10. Preferably, a USB connector is used as the data connector for the detection box 10.

[0032] In one embodiment, a bus connector 14 is further provided on the bottom surface of the detection box 10. The bus connector 14 has a bus interface, and the opening of the bus interface faces one side of the detection box 10. A bus window is provided on this side, and the bus interface corresponds to the bus window. It is understood that the power window, data connection window, and bus window are not limited to being located on any particular side of the detection box 10. They can be located on different sides or on the same side, and the specific arrangement can be adjusted according to actual needs.

[0033] Multiple screen aging test devices are connected to their respective bus connectors 14 via a CAN bus, thereby enabling cascaded control of multiple screen aging test devices through a processor, and simultaneously detecting multiple screens A under test.

[0034] The following describes in detail the cascaded control process of several screen aging test devices of this utility model:

[0035] The processor obtains USB access to enable communication with the microcontroller 30 and the color sensor 20.

[0036] The microcontroller 30 initializes and configures the color sensor 20 to prevent residual effects from the previous detection.

[0037] The processor has an open control interface for users to adjust the configuration status; specifically, the configuration status includes selecting test images, setting video frame rate, setting acquisition frequency, setting test duration, and timed testing, etc. The configuration status can be adjusted according to the user's actual needs.

[0038] The processor synchronizes the corresponding configuration status to all nodes of the screen aging test device via the CAN bus. After the nodes are synchronized, the color sensor 20 begins to detect the screen A under test to obtain color information. It can be understood that after synchronization is completed, the detection can be started manually or automatically.

[0039] The microcontroller 30 continuously acquires color information and converts it into stored color data;

[0040] The processor receives data from the microcontroller 30 at a set period and analyzes the data to obtain a single test result containing the sampling data of the screen under test A, the screen color information, and the abnormal information.

[0041] Once the test duration is reached, the processor ends the detection and summarizes all single test results to output a test report containing the number and probability of anomalies of the screen under test A and the corresponding anomaly time, thereby determining the aging status of multiple screens under test A.

[0042] This invention uses a color sensor installed in the testing box to detect the screen under test, which greatly reduces the pixel requirements, thereby reducing equipment costs and testing difficulty. At the same time, it sets up a corresponding control process to realize the cascaded control of multiple screen aging test devices, improving the testing efficiency of the screen under test.

[0043] The embodiments described above only illustrate the preferred implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
