Description

Technical Field

[0001] This invention relates to the field of color temperature detection technology for display devices, and more specifically to a test system and method for intelligently switching color temperatures and detecting the function of color sensors. Background Technology

[0002] Existing flat panel display products (such as monitors, televisions, tablets, etc.) have a color sensor function. This function uses the color sensor to sense the color temperature of the ambient light and then drives the display device to automatically adjust the screen's color temperature to provide users with a more comfortable and color-consistent viewing experience under different color temperature lighting environments.

[0003] Currently, the industry commonly uses manual operation for testing color sensor functionality. A typical testing process is as follows: First, the tester manually activates the color sensor function of the display device under test. Then, during the test, the tester manually operates a switch to sequentially change different types or color temperatures of test light sources. After each switch, the tester uses a separate color analyzer to manually read and record the current color temperature data displayed on the screen. Finally, the recorded data is manually compared to ensure it falls within acceptable standards, and the test results are manually determined. This manual testing method has the following drawbacks: low efficiency and poor consistency; and a lack of automated data management and judgment functions. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a test system and method for intelligently switching color temperature and detecting the function of color sensors, which automatically switches color temperature, collects data, compares and judges and generates reports, thereby improving test efficiency, accuracy and standardization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A testing system for intelligently switching color temperatures and detecting the color sensor function, characterized in that it includes: Control module; The relay is electrically connected to the control module; Multiple light sources with different color temperatures are grouped together, and each light source is electrically connected to a relay. The relay controls the independent on / off state of each light source to provide different color temperature illuminations required for testing. The color analyzer is connected to the control module and is used to collect color temperature data of the display device under test under different color temperature light sources, and transmit the collected color temperature data to the control module. The control module acquires color temperature data transmitted by the color analyzer, automatically compares the acquired color temperature data with preset standard values, and generates a test report based on the comparison results.

[0006] Furthermore, the probe of the color analyzer is mounted in the center of the display screen.

[0007] Furthermore, multiple light sources with different color temperatures are fixedly placed 1 meter in front of the color sensor.

[0008] The present invention provides a test method for intelligently switching color temperature and detecting the color sensor function, employing the aforementioned test system, characterized by comprising the following steps: Enable the color sensor function of the display device under test; The control module controls the relays to switch and light up light sources of different color temperatures in sequence. For each light source that is lit, the color analyzer collects the current color temperature data of the display device under test and transmits it to the control module, which then records it automatically. The control module automatically compares all recorded color temperature data with the preset standard value range and generates a test report based on the comparison results.

[0009] Furthermore, the test report includes the following: if all recorded color temperature data falls within the preset standard value range, the report result is "pass"; if there is color temperature data that does not fall within the preset standard value range, the report result is "fail".

[0010] By adopting the above technical solution, the beneficial effects of the present invention are as follows: This invention achieves automatic detection of display sensor functions by automatically switching light sources with different color temperatures and automatically reading and comparing data. It replaces traditional manual operation with automation, significantly improving testing efficiency and consistency. At the same time, the system automatically generates test reports, enhancing the traceability of the testing process and providing a data foundation for production quality control. Attached Figure Description

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Figure 1 This is a hardware block diagram of the test system of the present invention; Figure 2 This is a flowchart illustrating the testing method of the present invention. Detailed Implementation

[0012] like Figure 1 As shown, the present invention discloses a test system for intelligently switching color temperature and detecting the function of a color sensor, including a control module, a relay, multiple light sources with different color temperatures (such as LEDs with color temperatures of 2700K, 4000K, 5000K, 6500K, etc.) and a color analyzer.

[0013] The control module is an industrial computer or embedded controller with dedicated control software installed, which has data processing, logic judgment and instruction issuance functions.

[0014] The relay is a multi-channel relay module. The control input terminal of the relay is electrically connected to the control module, while the multi-channel switch output terminal of the relay is electrically connected to multiple light sources of different color temperatures. Through this connection method, the control module can send precise switching commands, which are executed by the relays to independently control the on and off of each color temperature light source.

[0015] The color analyzer establishes a communication connection with the control module via a data cable. The color analyzer's probe is securely mounted on a bracket and precisely aligned with the geometric center of the display screen under test to ensure the representativeness and accuracy of the collected data. The color analyzer is used to measure the color temperature and other chromaticity data of the display device under the current light source in real time and uploads this data to the control module in real time.

[0016] In a preferred embodiment, multiple light sources with different color temperatures are mounted in a clustered manner on a shared lamp holder to ensure that the light emitted by them illuminates the color sensor integrated on the display device from the same direction as much as possible, and the multiple light sources with different color temperatures are placed 1 meter directly in front of the color sensor to simulate a standardized test lighting environment.

[0017] like Figure 2 As shown, the test method of the present invention is as follows: Enable the color sensor function of the display device under test; The control module sends a command to the relay to close the first switch, illuminating the first light source of color temperature (e.g., 2700K) while simultaneously turning off other light sources of color temperature. After the display screen completes its adaptive adjustment and stabilizes, the control module triggers the color analyzer to perform its first measurement. The color analyzer transmits the measured screen color temperature data (e.g., 2750K) back to the control module, which records this data along with the corresponding light source number in its memory or database.

[0018] After the first recording is completed, the control module sends the next command to the relay to turn off the current color temperature light source and simultaneously turn on the second color temperature light source (e.g., 4000K). This measurement and recording process is repeated until all preset color temperature light sources have been sequentially turned on and data acquisition is complete.

[0019] After all color temperature light sources have been tested, the control module calls up the internally preset standard value range. For example, for a 2700K light source, the standard screen color temperature range can be preset to 2650K-2750K. The control module automatically compares the recorded actual data (2750K) with this range. The system checks the measurement data of all color temperature lamps one by one.

[0020] Based on the comparison results, the control module automatically generates a test report. The test report states: if all recorded color temperature data falls within the preset standard value range, the report result is "pass"; if any color temperature data does not fall within the preset standard value range, the report result is "fail". Furthermore, the test report can be presented in text, table, or chart format and can be automatically saved or printed.

[0021] The specific embodiments of the present invention have been described above. However, those skilled in the art should understand that this is merely an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principles and essence of the present invention, but all such changes and modifications fall within the protection scope of the present invention.
