Intermediate Luminance Level Generation via Pulse Width Differences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices lack the ability to continuously and discretely adjust screen luminance levels, limiting user experience by not allowing for finer gradations between existing luminance settings.
Innovation Solution
An electronic device method and system that generates a new luminance level by calculating differences in current amounts or pulse widths between adjacent existing luminance levels, allowing for intermediate luminance settings between the first and second luminance levels, thereby providing more precise control over screen brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional luminance adjustment methods are used, then device complexity is reduced, but luminance adjustment precision is insufficient
Solution Approach 1:
The patent segments the luminance adjustment range into multiple discrete levels by inserting intermediate luminance levels between adjacent existing levels. This is achieved by dividing the current amount or pulse width range into multiple segments, with each segment corresponding to a distinct luminance level. The segmentation allows for finer granularity in luminance control without requiring a complete redesign of the display hardware.
Solution Approach 2:
The patent introduces a new dimension to luminance control by creating intermediate luminance levels that exist between the original discrete levels. This dimensional expansion transforms the luminance adjustment from a coarse two-state (on/off) or limited discrete selection to a multi-level continuous-like adjustment, enabling smoother transitions and more precise brightness control.
2Measurement precision
If more luminance levels are provided, then luminance adjustment precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements dynamic luminance adjustment by allowing the display to automatically select appropriate luminance levels based on real-time conditions such as ambient light detection or content analysis. The system can dynamically transition between intermediate luminance levels to optimize display quality while maintaining user-friendly operation through automated adaptation rather than manual adjustment of multiple discrete levels.
3Manufacturing precision
If intermediate luminance levels are generated, then display quality is improved, but manufacturing complexity increases
Solution Approach 1:
The patent achieves improved display quality by dynamically adjusting control parameters (current amount or pulse width) to generate intermediate luminance levels. Rather than manufacturing hardware variations, the system achieves different luminance levels through software-controlled parameter changes, allowing the same display hardware to produce multiple luminance levels by modifying electrical parameters during operation.
