Display Driver Brightness Adjustment for Eye Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices do not effectively address eye comfort by adjusting display settings to reduce strain, particularly in terms of brightness levels and color temperature, which can lead to discomfort during prolonged use.
Innovation Solution
The electronic device includes a processor that identifies events indicating a need for eye comfort and adjusts the brightness level of characters and the entire screen, using display driver circuitry to enhance eye comfort by increasing brightness levels and reducing contrast ratios, while also adjusting color temperature and gamut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the brightness level of characters is increased to improve visibility and eye comfort, then the contrast ratio increases which may cause visual strain and reduce readability
Solution Approach 1:
The patent dynamically adjusts display parameters including brightness level, contrast ratio, color temperature, and gamut based on detected eye comfort events. When an eye comfort event is detected, the system increases brightness level while simultaneously adjusting contrast ratio and color temperature to optimize visual comfort and reduce eye strain during prolonged viewing.
2Measurement precision
If the contrast ratio is increased to improve character visibility, then readability improves but eye strain increases during prolonged use
Solution Approach 1:
The patent implements dynamic adjustment of display characteristics including contrast ratio, brightness, color temperature, and gamut based on real-time detection of eye comfort events. The system transitions from static display settings to adaptive settings that respond to user viewing conditions and duration, optimizing both readability and visual comfort over time.
3Object-affected harmful factors
If color temperature is reduced to improve eye comfort during nighttime use, then blue light exposure decreases but overall image quality and vibrancy may deteriorate
Solution Approach 1:
The patent adjusts multiple display parameters simultaneously including color temperature, brightness level, contrast ratio, and gamut based on detected eye comfort events and timing. During nighttime or prolonged viewing conditions, the system reduces blue light exposure by adjusting color temperature while compensating for potential image quality loss through coordinated adjustments of other parameters to maintain overall visual fidelity.

AI summary
An electronic device may comprise: a processor. The electronic device may comprise a display driving circuit operatively coupled to the processor. The electronic device may comprise a display panel operatively coupled to the display driving circuit. The processor may be configured to cause the electronic device to: provide the display driving circuit with first data for a screen including a character having a first brightness level, thereby displaying the screen on the display panel; and based on an event indicating activation of a function for eye comfort, detected while the screen is being displayed based on the first data, provide the display driving circuit with second data for the screen including the character having a second brightness level higher than the first brightness level, thereby displaying the screen on the display panel.
