Divided Screen Display Method for Widescreen Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The latest widescreen notebook computers with higher resolutions make it difficult for users to browse web pages and perform operations due to smaller, finer characters, as the screen is wider from left to right and narrower from top to bottom, leading to inconvenient viewing and operation.
Innovation Solution
A method for displaying divided screens, where the screen is parsed to determine the number of divided screens and their resolutions, with continuous video data retrieved and stored in consecutive memory addresses, allowing seamless display and automatic adjustment to enhance usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the screen resolution is increased to provide finer display quality, then the display precision is improved, but the character size becomes smaller making it difficult to browse and operate
Solution Approach 1:
The patent divides the single high-resolution screen into multiple divided screens (e.g., two or more regions), allowing the display to be segmented into separate viewable areas. This segmentation enables users to access different content regions without scrolling, effectively combining high display precision with improved operability by presenting content in manageable sections.
Solution Approach 2:
The patent transitions from a single-screen display paradigm to a multi-region display paradigm by utilizing the horizontal width of the widescreen display. Instead of increasing vertical scrollable content, the solution adds a horizontal dimension for content organization, allowing users to view multiple content regions simultaneously across the wide screen real estate.
2Area of stationary object
If the screen is made wider from left to right to provide more display area, then the display area is increased, but the characters appear smaller and finer
Solution Approach 1:
By segmenting the wide display area into multiple divided screens, the patent allows each segment to display content at an appropriate size. The total display area is maintained through the wide screen, while individual content regions preserve larger character sizes within their respective segments.
Solution Approach 2:
Different regions of the display are allocated for different purposes or content types, with each region optimized for its specific function. This allows the system to maintain large, easily readable characters in each local region while utilizing the full width of the display for overall content presentation.
3Stability of the object's composition
If continuous video data is stored in consecutive memory addresses for divided screens, then the display continuity is improved, but the memory management complexity increases
Solution Approach 1:
The patent merges the memory management of multiple divided screens into a single continuous memory address space. By storing video data for all divided screens in consecutive memory addresses, the system simplifies memory management while maintaining display continuity, as the video processing unit can read data sequentially without complex address mapping.
Data Source
AI summary
An electronic device has a display, a video memory, a video data buffer unit, a central processing unit, and a video processing unit. The central processing unit, according to a number of divided screens and a resolution for each of the divided screens, retrieves different but continuous video data corresponding to the resolution of each of the divided screens from the video data buffer unit, and stores the retrieved continuous video data in consecutive memory addresses in the video memory. The video processing unit reads in sequence the continuous video data stored in the video memory, and sends the continuous video data in sequence to the display according to a direction of arrangement of the divided screens such that video contents displayed on the divided screens by the display are continuous.
