Partial Screen Display Control for OLED Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices lack the ability to selectively display only interesting information without showing non-interesting information, failing to meet user convenience needs by always turning the full screen on or off.
Innovation Solution
A method and apparatus for an electronic device with a touch screen that allows users to selectively turn on or off specific areas of the screen by identifying user touches and controlling the display status through a processor, using either software or hardware mechanisms to manage display on/off based on preset environment information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the full screen is turned on to display information, then the user can view all information including interesting and non-interesting content, but power consumption increases and user convenience decreases due to displaying unnecessary information
Solution Approach 1:
The display screen is divided into multiple independently controllable regions. Each region can be selectively turned on or off based on whether it contains interesting information for the user. This segmentation allows the system to display only necessary portions of information while turning off irrelevant areas, thereby reducing power consumption without losing important information.
Solution Approach 2:
Different regions of the display screen are assigned different display states (on/off) based on their content relevance. Interesting information regions maintain display functionality while non-interesting regions are turned off. This local quality differentiation optimizes power consumption by activating only the portions of the display that provide value to the user.
2Loss of information
If the full screen is turned on to display all information, then complete information is available, but user convenience decreases due to having to filter through non-interesting information
Solution Approach 1:
The display is segmented into multiple regions that can be independently controlled. Users can selectively turn on only those regions containing interesting information while leaving other regions off. This eliminates the need for users to manually filter through non-interesting information across the entire screen, significantly improving ease of operation while preserving access to complete information when needed.
Solution Approach 2:
Instead of requiring the full screen to be active for information access, the system enables partial display action by activating only the specific regions containing interesting information. This partial action approach maintains information accessibility while reducing the operational burden on users by eliminating unnecessary display areas.
3Use of energy by moving object
If the full screen is turned off to save power, then power consumption decreases, but the user cannot view any information including interesting content
Solution Approach 1:
The display screen is divided into independently controllable regions. When power saving is needed, the system turns off non-essential regions while maintaining display functionality in regions containing interesting information. This segmentation enables the system to achieve partial power savings without completely losing information accessibility, as users can still view important content in the active regions.
Solution Approach 2:
Different regions of the display are assigned different power states based on content importance. Regions containing interesting information maintain display functionality while less important regions are turned off for power saving. This local quality approach ensures that power consumption is reduced while critical information remains accessible to users.
4Use of energy by moving object
If the full screen is turned off to save power, then power consumption decreases, but the display cannot be selectively controlled to show only interesting information
Solution Approach 1:
The display is divided into multiple independently controllable regions, enabling selective turning on/off of specific areas. This segmentation provides adaptability by allowing the system to adjust display behavior based on user needs and environmental conditions, while simultaneously achieving power savings by activating only necessary regions rather than the entire screen.
Solution Approach 2:
The display system transitions from a static full-screen on/off state to a dynamic region-by-region control mechanism. Each region can independently change its display state based on real-time requirements, providing versatility in display control while optimizing power consumption. This dynamic approach allows the system to adapt to varying user needs and information priorities.

AI summary
A method and apparatus for controlling display of an electronic device are provided. The method includes selecting a specific area of a screen by a user, and switching a display on/off status of the selected specific area of a screen. Wherein, the switching of the display on/off status comprises determining whether display of the specific area is on or off, and, if it is determined that the display of the specific area is on, supplying current to a pixel corresponding to the specific area, and, if it is determined that the display of the specific area is off, discontinuing the supply of the current to the pixel in the specific area.
