Multi-Region Display Driver Frequency Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with scalable displays, such as foldable or rollable devices, face issues with unnecessary heating and resource waste due to operating at a single high driving frequency across all execution screens, even when some screens can operate at lower frequencies.
Innovation Solution
An electronic device with a multi-driving method that optimizes the driving frequency for each execution screen by using a processor to identify the required frequency and control the display driver integrated circuit to drive different regions of the display at specific frequencies, allowing each screen to operate at its optimal frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display operates at a high driving frequency across all regions, then the execution screen quality is improved, but unnecessary heating and resource waste occur
Solution Approach 1:
The display is divided into multiple independent driving regions, each capable of operating at different driving frequencies. The display driver circuit is segmented to control different regions separately, allowing region 1 to run at 60Hz and region 2 at 120Hz simultaneously, thus avoiding unnecessary heating in regions that don't require high refresh rates
Solution Approach 2:
Different regions of the display are assigned different driving frequencies based on their specific requirements. Game content in region 2 receives 120Hz for smooth gameplay, while messaging or browsing in region 1 uses 60Hz, optimizing performance locally without wasting resources across the entire display
2Reliability
If the display operates at a high driving frequency across all regions, then the execution screen quality is improved, but resource waste occurs
Solution Approach 1:
The driving frequency of each display region is dynamically adjusted based on the content being displayed and the application requirements. The system can switch between 60Hz and 120Hz for different regions at different times, optimizing energy consumption while maintaining execution screen quality when needed
Solution Approach 2:
The driving frequency parameter is changed independently for different display regions based on application requirements. Low-frequency applications like messaging use 60Hz to conserve energy, while high-frequency applications like games use 120Hz, reducing overall power consumption and resource waste
3Adaptability or versatility
If multiple execution screens are output on divided display regions, then the functionality is improved, but the display must operate at the highest driving frequency among all screens
Solution Approach 1:
The display is segmented into multiple independently controllable regions, each capable of running at different frequencies simultaneously. This allows region 1 to display messaging content at 60Hz while region 2 displays game content at 120Hz, enabling multi-screen functionality without forcing the entire display to operate at the highest frequency
Solution Approach 2:
The display system is designed to support multiple functions simultaneously with different driving frequencies. The same physical display can universally support both 60Hz and 120Hz operations in different regions, allowing diverse applications like messaging, browsing, and gaming to run concurrently at their optimal frequencies

AI summary
An electronic device includes a display including a plurality of regions, a display driver integrated circuit configured to drive a first region of the display at a first driving frequency and drive a second region of the display at a second driving frequency according to a configuration of the display, and a processor configured to provide display data to the display driver integrated circuit. The processor identifies a driving frequency of a first screen to be output on the display in response to reception of a first input; and controls the display to output at least a portion of the first screen on a region, of the plurality of regions, driven at a driving frequency corresponding to the driving frequency of the first screen. The display optimizes driving frequency, thus reducing heating problems and resource waste in the electronic device.
