Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses lack user autonomy in dynamically adjusting backlight brightness according to personal preferences and environment, leading to suboptimal user experience due to pre-configured settings.
Innovation Solution
A display apparatus that allows users to set adjustable correspondence between environment brightness and backlight brightness, automatically detecting environment brightness and adjusting backlight based on user-defined settings, with options for manual adjustment and automatic backlight adjustment functions that do not interfere with each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic backlight adjustment function is enabled, then the display apparatus can automatically adjust backlight brightness according to environment brightness, but the user cannot manually adjust backlight brightness according to personal preferences
Solution Approach 1:
The patent divides the backlight adjustment functionality into two separate modes: automatic adjustment mode and manual adjustment mode. These modes are segmented as distinct operational states that can be independently selected, allowing the system to provide either automatic environment-based adjustment or manual user-controlled adjustment without interference between the two functions.
Solution Approach 2:
The patent implements dynamic switching between automatic and manual adjustment modes based on user selection. The system can transition from a static pre-configured state to a dynamic state where the user can choose the desired adjustment mode, and the system adapts its behavior accordingly to provide either automated or manual control.
2Adaptability or versatility
If pre-configured backlight settings are used, then the display apparatus provides standardized display effect, but the user experience is suboptimal due to lack of personalization
Solution Approach 1:
The patent provides pre-configured backlight adjustment correspondence between environment brightness and backlight brightness as a default setting. This preliminary configuration allows the system to immediately provide functional backlight adjustment capabilities without requiring complex user setup, while still enabling personalized adjustments when users access the adjustment interface.
Solution Approach 2:
The patent introduces an adjustment interface as an intermediary between the user and the backlight adjustment system. This interface mediates the complexity by providing a simplified method for users to input their preferences, which then translates into appropriate backlight settings without requiring users to understand the underlying complex adjustment mechanisms.
3Ease of operation
If manual backlight adjustment is allowed, then user autonomy is improved, but the automatic backlight adjustment function may be interfered with
Solution Approach 1:
The patent implements dynamic mode switching that allows the system to transition between automatic and manual adjustment states. When in automatic mode, the system reliably adjusts backlight based on environment brightness sensing. When users need manual adjustment, they can switch to manual mode where they have full autonomy. The system dynamically adapts to the current mode to ensure neither function interferes with the other.
Solution Approach 2:
The patent extracts the manual adjustment capability as a separate, independent function that can be activated or deactivated independently from the automatic adjustment function. This extraction allows users to have manual autonomy when needed while preserving the automatic function's reliability when manual intervention is not required, eliminating interference between the two modes.
