Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display detection circuit and circuit protection board. Background Technology

[0002] In the production and quality inspection of displays, the detection of optical performance such as screen brightness uniformity and color temperature consistency is crucial. Traditional detection methods mostly rely on manual visual inspection or a single photoelectric sensor combined with manual dimming equipment, which has the following significant drawbacks: manual visual inspection is easily affected by subjective factors and cannot quantify brightness deviation; existing single-point light sensors require scanning area by area, which takes several minutes per unit, making it difficult to meet the high-speed inspection requirements of production lines.

[0003] In conventional solutions, functional modules such as brightness acquisition, LED driver control, and signal transmission are scattered and independent, requiring multiple devices to work together, resulting in complex wiring, poor compatibility (such as conflicts between different interface protocols), and high maintenance costs.

[0004] Most testing equipment can only record static brightness data and lacks the ability to interact with the testing machine in real time.

[0005] Therefore, there is an urgent need for a low-cost, highly integrated display detection circuit with real-time interactive capabilities to meet the stringent requirements of modern production lines for efficiency, accuracy, and reliability. Utility Model Content

[0006] To address the above technical problems, this application proposes a display detection circuit and a circuit protection board.

[0009] By integrating the testing of multiple components onto a single board, the time required to disassemble and replace testing equipment during the testing process can be reduced, thereby accelerating the overall production process and improving production line efficiency.

[0010] A single board can complete the testing of multiple components, avoiding complex disassembly and assembly and multiple inspections, thus improving the convenience and efficiency of testing.

[0011] Multiple testing functions are integrated on one board, saving space, reducing the need for testing equipment, making the production line layout more compact, and reducing hardware investment.

[0012] Integrated testing systems help ensure consistency in testing standards and avoid errors between different testing devices, thereby improving the controllability of product quality.

[0013] Furthermore, the test board includes a display screen interface for connecting a display screen; the display screen displays performance parameters during the test process.

[0014] Furthermore, the performance parameters include the ambient brightness of the light sensor.

[0015] By using the display interface in the test panel, the performance parameters of the light sensor, such as the ambient brightness, can be displayed in real time. This helps operators to understand key data during the testing process and ensures the accuracy of the test.

[0016] The display screen can clearly show the ambient brightness data during the test, allowing operators to monitor changes in ambient light in real time and adjust test conditions or equipment status as needed.

[0017] By displaying performance parameters such as ambient brightness, operators can gain a comprehensive understanding of the light sensor's operating status and make adjustments based on the displayed test data, enhancing the transparency and operability of the testing process.

[0018] By accurately displaying the ambient brightness parameters of the light sensor, it is possible to promptly identify external lighting factors that may affect the display's performance, thereby enabling optimization and adjustments, and ensuring the accuracy and reliability of test results.

[0019] Furthermore, the detection converter includes a testing machine interface for connecting to the testing machine.

[0020] Furthermore, the optical sensor communicates with the testing machine through the detection turntable; the testing machine transmits display signals to the display screen.

[0021] The test board includes a tester interface, which facilitates the connection of the tester to the testing circuit, improving the system's interconnectivity. The tester can directly connect and communicate with external testing devices, greatly simplifying equipment integration and expansion.

[0022] Through the detection converter, the optical sensor can communicate with the testing machine in real time. The testing machine acquires signals from the optical sensor through the converter and can quickly process these signals, thereby ensuring efficient and accurate data transmission during the testing process and reducing delays and errors in signal transmission.

[0023] The testing machine can transmit processed signals to a display screen to show test results in real time. This design allows operators to quickly obtain test information and make necessary adjustments. Real-time display enhances the system's operability, enabling users to respond quickly and optimize the testing process.

[0024] Through communication between the testing machine and the inspection turntable, the entire testing process can be more automated. The working status of the optical sensor and the operation of the testing machine can be automatically controlled, reducing manual intervention and improving testing efficiency and intelligence.

[0025] A reliable connection and data transmission are established between the testing machine and the optical sensor via a detection converter, ensuring high stability during testing. Accurate signal transmission and display feedback enhance the overall performance and reliability of the system.

[0026] Secondly, this application proposes a circuit protection board, which includes the display detection circuit and the circuit board described in the first aspect, wherein the display detection circuit is integrated on the circuit board.

[0036] Switch and LED: The switch and LED are connected in series via a converter circuit. The LED indicates the display's operating status. When the display is in normal working condition, the LED lights up, controlled by a signal from a light sensor; in case of a fault or abnormality, the LED turns off or provides feedback in other ways. In this embodiment, the LED is an AP2012SG LED, using SMD packaging technology, suitable for automated production, small in size, and easy to assemble in various electronic products. The AP2012SG provides high brightness, meeting the needs of applications requiring strong illumination. Compared with traditional lighting technologies, LEDs are energy-efficient and have a long lifespan, making them suitable for energy-saving lighting solutions. Furthermore, this LED has high operational stability, suitable for long-term use.

[0037] It is widely applicable to automotive lighting, instrument displays, electronic displays, backlights, indoor and outdoor lighting, etc.

[0038] Connector module: It connects the above components through electrical connection to realize signal transmission. The connector module can ensure stable signal transmission and connect to external devices through the detection adapter.

[0039] Detection adapter board: As a key component of this circuit, the detection adapter board connects the detection circuit to other external components. Its wiring design makes signal transmission from switches, LEDs, and connectors more efficient and stable.

[0040] This embodiment, through its structure, enables real-time monitoring of the display's status. When the display's status changes, the signal detected by the light sensor is transmitted to the detection circuit, which then uses LEDs and switches to provide feedback on the display's operating status, thus improving the reliability and intelligence of the detection process.

During testing, the display screen connects to the testing turntable via this interface, enabling real-time display of various performance parameters during the testing process, such as changes in LED light intensity and on / off status.

[0045] In this embodiment, a key performance indicator is the ambient brightness detected by the light sensor.

During the test, the light sensor collects ambient brightness data in real time and transmits it to the display interface via the detection circuit, where it is displayed on the screen.

[0046] When the monitor is running, the light sensor detects changes in the brightness of the surrounding environment and feeds the data back to the display screen via the detection circuit. The display screen receives the data through the display interface and dynamically displays performance parameters such as ambient brightness, providing technicians with real-time display status feedback.

[0047] This design allows for a more intuitive observation of the display's operating status and changes in ambient brightness, ensuring that the performance of the light sensor is effectively tested and verified.

The light sensor's signal is transmitted to the testing machine via the turntable. The testing machine processes and analyzes the received signal, calculating the light sensor's performance according to a preset algorithm. The testing machine then generates a display signal from the analyzed test results and transmits it to the display screen.

In this embodiment of the invention, the optical sensor transmits signals to the testing machine via the detection converter board through the SDA and SCL connection lines.

[0056] The optical sensor transmits the collected optical signal data to the detection turntable via the built-in I2C communication protocol, through the SDA connection line (data line) and the SCL connection line (clock line).
