Solution Overview
Problem
Flash visual effects in shooting games, such as those caused by flashbangs, lead to discomfort and impaired player response due to high brightness, affecting gaming experience and win rates.
Innovation Solution
A display device equipped with a processor and display controller that uses machine learning models, particularly regional convolutional neural networks, to detect trigger events like flashbangs, adjusting brightness levels to mitigate the impact of these effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flash visual effects are displayed with high brightness to simulate flashbang impact, then the visual effect realism is improved, but player comfort and response time deteriorate
Solution Approach 1:
The patent dynamically changes the brightness parameter of the display based on detected flashbang events. When a flashbang is detected in the game, the display controller adjusts the brightness parameter from normal levels to suppressed levels, and then restores it after the effect ends. This parameter change resolves the contradiction by maintaining visual realism when needed while protecting player comfort during harmful flash effects.
Solution Approach 2:
The patent introduces a brightness suppression mechanism as an intermediary between the game output and the display. This intermediary layer detects flashbang events and selectively adjusts brightness without affecting the game's visual effect generation. The mediator allows the game to maintain realism while the display protection layer filters out harmful brightness levels.
2Object-affected harmful factors
If brightness suppression is applied during flashbang effects, then player comfort is improved, but visual effect impact is reduced
Solution Approach 1:
The patent applies brightness suppression periodically rather than continuously - only during the specific time window when flashbang effects are detected. The system activates brightness suppression when the flashbang event occurs, maintains it during the effect duration, and deactivates it afterward. This periodic application preserves visual effect impact when needed while providing comfort protection only during harmful moments.
Solution Approach 2:
The brightness parameter is dynamically adjusted based on the temporal characteristics of flashbang effects. The system changes brightness from normal to suppressed state during the flashbang event duration, then restores it afterward. This time-dependent parameter change maintains visual fidelity for regular game content while protecting players during intense flash effects.
3Measurement precision
If machine learning models are used to detect trigger events, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts and utilizes only the essential detection capability needed for flashbang identification from machine learning models. Rather than implementing full ML infrastructure, the system extracts the specific function of detecting high-brightness flash events in game content. This extraction approach achieves sufficient detection accuracy while minimizing the complexity overhead of machine learning systems.

AI summary
A method, an electronic device (600), and a display device (100) for suppressing a brightness (B1) of the display device (100) are provided. The method includes the following. An image signal is received. The image signal is detected to determine whether a trigger event occurs. Also, in response to the trigger event occurring, the brightness (B1) of an output image of the display device (100) is suppressed, in which the display device (100) generates the output image according to the image signal.
