Display Driver Integrated Circuit Rendering Transition Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display mode transition technologies face challenges with power consumption and smoothness, particularly in ultra-high definition displays, due to overload of the application processor delaying screen display transition effects.
Innovation Solution
An electronic device with a display driver integrated circuit that determines its operation state upon receiving a display mode transition command signal, allowing it to control the display panel to render a screen display transition effect and switch to a second image upon completion of the transition, thereby managing rendering on behalf of the application processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the application processor renders the screen display transition effect during display mode transition, then the transition effect can be displayed, but the application processor becomes overloaded and delays rendering, causing non-smooth transitions
Solution Approach 1:
The patent extracts the screen display transition effect rendering function from the application processor and transfers it to the display driver integrated circuit. This separation allows the application processor to focus on other tasks while the DDI handles the transition rendering, preventing overload and ensuring smooth transitions without delays.
Solution Approach 2:
The display driver integrated circuit acts as an intermediary between the application processor and the display panel. It receives the display mode transition command from the application processor and independently generates and renders the screen display transition effect, mediating the transition process to ensure smooth visual changes without burdening the application processor.
2Reliability
If the application processor handles display mode transition rendering, then the transition can be rendered, but power consumption increases due to processor overload
Solution Approach 1:
The patent extracts the transition rendering workload from the application processor and assigns it to the display driver integrated circuit. This extraction reduces the computational burden on the application processor, thereby lowering overall power consumption while maintaining reliable transition rendering capability through the DDI's dedicated rendering resources.
Solution Approach 2:
The display driver integrated circuit performs self-service by independently generating and rendering the screen display transition effect without requiring continuous intervention from the application processor. This self-sufficient approach reduces the active time and power consumption of the application processor while ensuring reliable transition rendering.
3Productivity
If the display driver integrated circuit renders the screen display transition effect, then power consumption is reduced and smoothness is improved, but the device complexity increases
Solution Approach 1:
The display driver integrated circuit serves as an intermediary that absorbs the additional rendering functionality. Rather than adding a completely new component, the patent leverages the existing DDI as a mediator between the application processor and display panel, integrating transition rendering capabilities into the existing architecture to minimize overall system complexity.
Solution Approach 2:
The display driver integrated circuit is designed with multi-functionality, handling both traditional display driving tasks and the additional screen display transition effect rendering. This universal approach allows one component to perform multiple functions, reducing the need for additional dedicated hardware and thereby limiting the increase in device complexity.
