[0002] With the continuous development of science and technology, people's requirements for eye protection technology of displays have also increased.

[0020] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] like Figure 1 As shown, the embodiment of the present application provides a control method for an eye protection display, including: S1 collects data on changes in the user's pupil diameter in real time; S2 obtains the user's blink frequency and blood oxygen saturation; S3 obtains the user's head micro-movement signal; S4 determines a visual fatigue index based on the change data of the user's pupil diameter, the user's blinking frequency, the user's blood oxygen saturation, and the user's head micro-movement signal; S5 adjusts display parameters of the eye protection display according to the visual fatigue index.

[0023] The visual fatigue index is determined by the change data of the user's pupil diameter, the user's blinking frequency, the user's blood oxygen saturation and the user's head micro-movement signal; the display parameters of the eye protection display are adjusted according to the visual fatigue index, which greatly improves the intelligence of the display, no longer relies on the ambient light sensor, establishes a closed-loop control of physiological signals and display parameters, and improves the eye protection effect.

[0024] like Figure 2 As shown, for example, as an optional implementation, it also includes: judging whether the user is currently in a high-risk fatigue state based on the change data of the user's pupil diameter and the user's blinking frequency; if the user is currently in the high-risk fatigue state, controlling the display parameters of the eye protection display to be high-risk fatigue parameters.

[0025] As an optional implementation, the high-risk fatigue parameters are: 100% blue light reduction rate and 5000 Hz PWM dimming.

[0026] As an optional implementation, determining whether the user is currently in a high-risk fatigue state based on the change data of the user's pupil diameter and the user's blinking frequency includes: if the user's current blinking frequency is greater than 20 times / minute and the fluctuation amplitude of the pupil diameter is greater than 30%, it is determined that the user is currently in a high-risk fatigue state.

[0027] As an optional implementation, the real-time collection of the change data of the user's pupil diameter includes: collecting the change data of the user's pupil diameter in real time through a millimeter wave radar, with a sampling frequency ≥100 Hz.

[0028] The millimeter-wave radar sensor has a detection range of 0.2-1m, a thickness of ≤3mm, and the ability to penetrate non-metallic obstructions. It operates at a frequency of 60GHz±5GHz and can be embedded in the upper frame of a display to penetrate the user's glasses to monitor pupil diameter changes in real time. The sampling rate is ≥100Hz and the detection accuracy is ±0.1mm.

[0029] As an optional implementation manner, obtaining the user's blinking frequency and the user's blood oxygen saturation includes: obtaining the blinking frequency and the blood oxygen saturation through an infrared sensor.

[0030] Specifically, an infrared sensor with a wavelength of 850nm can be used and set at the lower frame of the display to synchronously detect blinking frequency and blood oxygen saturation, with an SpO2 measurement error of ≤±2%.

[0031] As an optional implementation, determining the visual fatigue index based on the change data of the user's pupil diameter, the user's blinking frequency, the user's blood oxygen saturation and the user's head micro-movement signal includes: inputting the change data of the user's pupil diameter, the user's blinking frequency, the user's blood oxygen saturation and the user's head micro-movement signal into an LSTM model, and outputting the visual fatigue index.

[0032] Specifically, the input dimension of the LSTM model can be 4 (corresponding to pupil diameter, blinking frequency, blood oxygen saturation, and head movement), the hidden layer dimension can be 32, and the fatigue index prediction accuracy can reach 92.7%.

[0033] It integrates a 60GHz millimeter-wave radar and an 850nm infrared sensor, capable of penetrating glasses to monitor pupil diameter changes in real time with an accuracy of ±0.1mm and a sampling rate ≥100Hz. It can also detect blinking frequency and blood oxygen saturation with an SpO2 error of ≤±2%. Based on the LSTM model, it fuses pupil data, blinking frequency, blood oxygen saturation, and head micro-movement signals to output a 0-100% visual fatigue index (with a prediction accuracy of 92.7%), providing a 15-minute advance warning of fatigue risks. It dynamically reduces harmful blue light from 415-455nm based on the fatigue index (reduction rate of 10-100%), synchronously enhances 580-600nm amber light to compensate for chromatic aberration (ΔE < 1.5), and increases the PWM dimming frequency to ≥5000Hz (brightness fluctuation depth <5%).

[0034] The integration of millimeter-wave radar and infrared sensing for monitoring overcomes the limitations of traditional solutions that rely on ambient light or cameras, enabling precise collection of physiological signals without privacy leaks. A "physiological signal → AI prediction → spectral closed-loop adjustment" mechanism dynamically adapts to individual eye conditions, resolving the industry challenge of balancing eye protection with display quality (Comparative example: Philips SoftBlue technology improves eye protection by 40%). Through 5000Hz ultra-high frequency dimming and dynamic spectral compensation, the system eliminates the risk of flicker (SVM < 0.4) while ensuring color reproduction (ΔE < 1.5). As an optional implementation, adjusting the display parameters of the eye protection display according to the visual fatigue index includes: proportionally reducing the blue light spectrum and increasing the amber light intensity; wherein the blue light spectrum reduction rate = fatigue index × 1.25.

[0035] Specifically, blue light reduction can use quantum dot backlight technology to dynamically compress the energy in the 415-455nm band, and amber light compensation can maintain color gamut integrity by increasing the excitation intensity of 580-600nm phosphors.

[0036] In addition, an ambient light sensor may be included to collect ambient light intensity and color temperature data, and synchronously fuse the ambient light data to generate a visual fatigue index.

[0037] For example, when the visual fatigue index is ≥80%, the blue light reduction rate can be controlled to ≥60%; the screen brightness is reduced to ≤80cd / m 2 Activate local area dimming and increase the brightness of the gaze area by 10-20% based on pupil positioning data.

[0038] According to another aspect of this application, Figure 3As shown, an eye protection display is provided, and a control method applied to the eye protection display includes: a millimeter wave radar sensor for collecting real-time data on changes in the user's pupil diameter; an infrared sensor for obtaining the user's blinking frequency and the user's blood oxygen saturation, as well as obtaining the user's head micro-movement signal; an AI analysis engine for determining a visual fatigue index based on the user's pupil diameter change data, the user's blinking frequency, the user's blood oxygen saturation, and the user's head micro-movement signal; and a dynamic spectrum adjustment module for adjusting display parameters of the eye protection display according to the visual fatigue index.
