Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eye protection technologies fail to adequately address eye strain and fatigue caused by using mobile devices in low-light environments, particularly at night, due to insufficient integration of ambient lighting with display screen images.
Innovation Solution
A display device with a divided screen into multiple regions, each with specific light emitters that emit light matching the brightness and color of the corresponding display region, expanding and coordinating with the image to reduce eye strain.

Engineering Contradiction Analysis
1Reliability
If existing eye protection technologies are used, then some basic protection is provided, but the eye protection effect is unsatisfactory due to insufficient integration of ambient lighting with display screen images
Solution Approach 1:
The display screen is divided into multiple display regions, and light emitters are correspondingly divided into multiple groups. Each group of light emitters is associated with a specific display region, enabling independent control and matching of ambient light to different screen areas. This segmentation allows for region-specific eye protection adjustments, improving the overall eye protection effect by addressing different viewing conditions in different areas of the screen.
Solution Approach 2:
Different display regions may display different content with different brightness and color characteristics. The patent applies local quality by allowing each group of light emitters to emit light with specific brightness and color temperature that matches its corresponding display region. This enables localized adjustment of ambient lighting to complement the specific content being displayed in each region, enhancing visual comfort and reducing eye strain more effectively than uniform ambient lighting.
2Object-affected harmful factors
If the light emitter emits light to illuminate the environment, then the ambient light matches the display region reducing eye strain, but the device complexity increases due to multiple light emitters and control mechanisms
Solution Approach 1:
The light emitters serve multiple functions: they emit light to illuminate the environment around the display screen, match the brightness and color of specific display regions, and collectively contribute to overall eye protection. By making the lighting system multi-functional, the patent reduces the need for separate components for each function, thereby managing device complexity while achieving comprehensive eye protection effects.
Solution Approach 2:
The patent combines the display function and ambient lighting function into an integrated system. The light emitters are controlled based on display information from the screen, merging the control of display content and ambient lighting into a unified system. This integration allows the device to simultaneously perform display and eye protection functions, reducing the need for separate complex control mechanisms.
3Object-affected harmful factors
If the display screen is in a dark environment, then the contrast between screen and environment is high causing eye fatigue, but increasing the ambient light requires additional energy consumption
Solution Approach 1:
The light emitters are controlled to emit light periodically or dynamically based on the display content and environmental conditions. Rather than continuous operation at fixed intensity, the lighting system adjusts its emission in response to changes in display information and ambient conditions, enabling energy-efficient operation while maintaining eye protection benefits during periods when high illumination is not immediately required.
Solution Approach 2:
The patent dynamically changes parameters of the light emitters including brightness and color temperature, based on the display information and environmental conditions. By adjusting these parameters to match the display content and ambient conditions, the system achieves effective eye protection while optimizing energy consumption - emitting sufficient light only when and where needed rather than operating at constant high intensity.

AI summary
An eye protection method, a display device, an eye protection apparatus, and a storage medium. The eye protection method comprises: if a display screen is in a screen-on state and the brightness of an environment where the display screen is located is lower than a first brightness threshold, acquiring display information of a plurality of display areas of the display screen; determining corresponding driving information according to the display information; determining a corresponding light -emitting device according to the position of each display area on the display screen; and driving, according to the driving information, the corresponding light -emitting device to emit light, so that the emitted light matches each display area. The eye protection method can provide better visual experience for a user.
