[0037] Embodiment 1

[0038] Please refer to Figure 1Embodiment 1 of the present invention provides a display screen lighting test device with an infrared eye tracking function, including an eye tracking device 1 for real-time detection of an operator's eye movement trajectory and a display screen test system device 2, wherein the display screen test system device 2 is used to drive display screens to be tested with different interfaces, different sizes, and different types (LCD or OLED), and simultaneously provide power to the eye tracking device 1, send command signals to the eye tracking device 1, and receive feedback signals from the eye tracking device 1, wherein the eye tracking device 1 is electrically connected to the display screen test system device 2 and signal-connected, and the display screen test system device 2 includes a power supply module 2 for providing stable power supply to the entire device. 1. A signal total integration module 22 for signal acquisition, transmission, processing and feedback, a display screen interface module 23 for connecting to a display screen to be detected, a touch screen control and display module 24 for controlling the signal total integration module 22 and displaying test results, and an alarm prompt module 25 for outputting comparative test results, wherein the power supply module 21 is electrically connected to the signal total integration module 22, the signal total integration module 22 is electrically connected and signal-connected to the display screen interface module 23, the signal total integration module 22 is electrically connected and signal-connected to the touch screen control and display module 24, and the alarm prompt module 25 is electrically connected and signal-connected to the signal total integration module 22.

[0039] The eye tracking device 1 includes an infrared light source module 11, an eye image acquisition module 12 and an infrared image processing module 13; the infrared light source module 11 is used to emit infrared light to the eye; the eye image acquisition module 12 is used to collect infrared light information returned by the eye; the infrared image processing module 13 is electrically connected to the eye image acquisition module 12, and is used to process the returned infrared light information, calculate the movement trajectory and gaze time of the eye, and input the movement trajectory and gaze time of the eye into the signal integration module 22.

[0040] The signal integration module 22 includes a display screen signal processing unit 221, a LOG data storage unit 222, a voltage and current setting unit 223 and a peripheral interface unit 224; one side of the display screen signal processing unit 221 is electrically connected to the eye tracking device 1 (more specifically, one side of the display screen signal processing unit 221 is electrically connected to the infrared image processing module 13 of the eye tracking device 1), and the other side is electrically connected to the alarm prompt module 25, which is used to compare the data of the lighting test screen of the display screen to be detected and the data of the real-time eye movement trajectory of the operator with the inspection trajectory and It takes time to perform comparison processing to determine whether the inspector is checking the display screen. If not, the lighting test screen of the display screen to be tested will be automatically locked, and the comparison result will be transmitted to the alarm prompt module 25 for alarm prompt, prompting or reminding the operator that the test has not been completed, ensuring that the lighting test of the display screen can be effectively checked, and ensuring that the display screen product is checked by the operator according to the specifications. As a fool-proof measure for the lighting test of the display screen, it can eliminate human missed inspections, avoid the outflow of defective products, improve product quality, reduce the company's cost loss and reduce the outflow of defective products to the client, and improve customer satisfaction.

[0041] Specifically, first, the display screen signal processing unit 221 reads which screen the display screen to be tested is checking from the data of the lighting test screen of the display screen to be tested; secondly, the display screen signal processing unit 221 reads the trajectory and time actually checked by the operator from the data of real-time detection and recording of the eye movement trajectory; finally, the display screen signal processing unit 221 reads the preset inspection trajectory and time (i.e., the inspection time must be greater than or equal to a certain number of seconds) from the test program and compares them with the actual inspection trajectory and time. If the actual inspection trajectory and time are within the preset inspection trajectory and time, the inspection is qualified and the next screen is normally switched to continue the inspection; if any of the actual inspection trajectory and time is not within the preset inspection trajectory and time, the inspection is unqualified, the screen of the display screen to be tested is locked, the alarm prompt module 25 issues an alarm prompt, and at the same time, the touch screen control and display module 24 displays unqualified, so that the operator's screen switching button cannot be used, and the device prompts to restart the test until all the lighting test screens of the display screen to be tested are qualified.

[0044] The peripheral interface unit 224 is electrically connected to the display screen signal processing unit 221, and is used to provide a communication interface for instruments outside the device. The communication interfaces provided by the peripheral interface unit 224 include RS232, RS485, USB and LAN, so as to facilitate communication with instruments or equipment outside the device, for example: inputting eye tracking programs and test programs, etc.

[0045] The power supply module 21 includes a main power switch unit 211, which controls the power on and off of the entire device.

[0049] The display screen interface module 23 integrates multiple communication interfaces for lighting up display screens of different interfaces and types. The communication interfaces of the display screen interface module 23 include MIPI, LVDS, EDP and SPI interfaces. The above interface types can meet the needs of existing commonly used display screens of different sizes. After determining the display screen interface, the corresponding program can be debugged to perform detection.

[0050] The eye tracking device 1 and the display screen test system device 2 are in constant communication, and the display screen test system device 2 determines whether the lighting test screen of the display screen to be tested is completely checked and whether the lighting test screen can be switched to the next lighting test screen.

[0051] The present invention can detect display screens of different sizes or different types. The placement angle, inspection content or time of the display screen to be detected are all different, and an eye tracking algorithm program needs to be set for different display screens to be detected.

[0052] In the first embodiment, the infrared image processing module 13 is fixed on a bakelite frame on one side of the display screen to be detected, and is then connected to the display screen signal processing unit 221 in the signal integration module 22 via a peripheral interface unit 224 .
