Display Apparatus Visibility Balance Control for Stroke Content Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face difficulties in distinguishing between content and handwritten strokes, especially when they are close in color, leading to reduced visibility and limited user control over transparency settings, particularly in interactive whiteboard environments.
Innovation Solution
A display apparatus with a visibility balance setting unit that includes a content transparency setting unit and a stroke background transmittance setting unit, allowing users to adjust the transparency of content and the background of handwritten strokes independently, enabling better differentiation and visibility control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content and stroke are displayed in overlaid mixture, then both content and stroke can be displayed on the same sheet, but visibility and differentiation between content and stroke are reduced
Solution Approach 1:
The patent segments the display into three independent layers: content layer, stroke layer, and background layer. Each layer can be independently controlled for transparency and visibility, allowing users to differentiate between content and strokes even when displayed together on the same sheet.
Solution Approach 2:
The patent applies different transparency settings to different regions and elements. The background can be set to translucent to allow handwriting visibility, while content and strokes maintain their own visibility characteristics. This local differentiation resolves the visibility conflict between overlaid content and strokes.
2Loss of information
If background is set to translucent to improve handwriting visibility, then handwriting becomes more visible, but content and stroke still co-exist in mixture without clear differentiation
Solution Approach 1:
The patent introduces dynamic control mechanisms that allow users to adjust transparency and visibility settings in real-time. Users can switch between different display modes (translucent background mode, content transparency mode, stroke background transmittance mode) and make fine adjustments to differentiate content from strokes as needed.
Solution Approach 2:
The patent changes key display parameters including background translucency, content transparency, and stroke background transmittance. By adjusting these parameters independently, users can optimize visibility for different scenarios such as handwriting input, content review, or stroke emphasis.
3Loss of information
If content transparency and stroke background transmittance are adjusted independently, then visibility balance is improved, but device complexity increases
Solution Approach 1:
The patent implements a unified visibility balance setting unit that handles multiple functions: background translucency control, content transparency adjustment, and stroke background transmittance control. This multi-functional approach manages complexity by providing a single interface for all transparency-related adjustments rather than separate controls for each parameter.

AI summary
A display apparatus includes an object display unit that displays in a display region an object including a content, and a stroke drawn on the content in an overlaid fashion, and a visibility balance setting unit that sets a visibility balance of the displayed content. The visibility balance setting unit includes a content transparency setting unit that sets content transparency serving as transparency of the content, and a stroke background transmittance setting unit that sets stroke background transmittance that is transmittance of a background of the drawn stroke.
