Display Grayscale Control for Flashbang Brightness Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flashbangs in shooting games cause sudden screen brightness changes, leading to user discomfort and delayed response due to the screen turning completely void and taking time to recover.
Innovation Solution
A display device with adjustable grayscale values that includes a controller to detect and adjust pixel brightness levels, reducing grayscale values when thresholds are met to mitigate sudden brightness changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the screen displays a flashbang effect with high grayscale values, then the visual impact of the flashbang is enhanced, but user comfort deteriorates and response time increases
Solution Approach 1:
The patent applies dynamics by making the grayscale value adjustable rather than fixed. The controller dynamically changes the grayscale value based on detected screen content: using a first grayscale value (higher) when no flashbang is detected, and switching to a second grayscale value (lower) when a flashbang is detected, thereby adapting the display to different game situations to balance visual impact with user comfort and response time
Solution Approach 2:
The patent directly applies parameter changes by modifying the grayscale value parameter of the display. The controller detects flashbang effects through image processing and automatically adjusts the grayscale parameter from a first value to a second value, changing the display characteristics to reduce the harmful effect of complete screen void while maintaining game playability
2Illumination intensity
If the screen turns completely void during a flashbang, then the flashbang visual effect is achieved, but user eye comfort deteriorates
Solution Approach 1:
The patent converts the harmful effect of complete screen void during flashbang into a beneficial effect by detecting the flashbang situation and automatically adjusting the grayscale value. Instead of allowing the screen to go completely void (harmful to eyes), the system uses image processing to detect the flashbang and applies a compensatory grayscale adjustment that maintains enough visibility to protect user eye comfort while still conveying the flashbang effect
Solution Approach 2:
The patent implements feedback through a closed-loop system where the controller continuously monitors the display content, detects flashbang effects using image processing algorithms, and automatically adjusts the grayscale value in response. This feedback mechanism enables the system to recognize harmful situations (complete screen void) and automatically correct them by adjusting display parameters, thereby eliminating eye discomfort caused by flashbang effects
3Stability of the object's composition
If the screen gradually returns to normal after a flashbang, then the visual transition is smooth, but user response speed deteriorates
Solution Approach 1:
The patent applies preliminary action by detecting the flashbang effect in advance through image processing and proactively adjusting the grayscale value before the screen completely voids. By anticipating the harmful effect and taking preemptive action to adjust the display parameter, the system prevents the complete screen void from occurring, thereby maintaining user response speed while still achieving the flashbang visual effect
Data Source
AI summary
A display device with adjustable grayscale values and a display method thereof are provided. The display device includes a display panel, a communication interface, and a controller. The communication interface is used to receive display data of a display screen. The controller is electrically connected to the display panel and the communication interface, and is used to drive the display panel to display a display screen according to the display data. In response to the controller performing the flashbang assist function, the controller analyzes the display data to detect multiple grayscale values of multiple pixels in the display screen. In response to the controller detecting that the grayscale values of the pixels in the display screen are all higher than or equal to the first threshold, the controller adjusts the display data to reduce at least part of the grayscale values.
