Interface Board Panel Driving Data Retrieval for Display Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The varying specifications of display panels, such as resolution and backlight module driving voltage, require different hardware and firmware designs for interface boards, leading to increased manufacturing costs due to the need for customized components.
Innovation Solution
A display device with an interface board featuring a system control module and system storage module that retrieves panel driving data through a connecting interface, allowing for the generation and transmission of an intimating signal to determine connection and drive the display panel using specific panel driving parameters, including voltage and current settings for the backlight module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different hardware and firmware designs are implemented for interface boards to meet varying display panel specifications, then the display panel can be properly driven, but manufacturing costs increase
Solution Approach 1:
The interface board is designed with a universal architecture that can support multiple display panel specifications. The system control module can retrieve and process different types of panel data (EDID, gamma data, lookup tables) for various panel types, and the system storage module stores multiple groups of panel driving data corresponding to different specifications. This allows a single interface board design to adapt to different display panels without requiring customized hardware or firmware for each specification.
2Ease of manufacture
If a standardized interface board design is used for different display panels, then manufacturing costs are reduced, but the ability to accommodate different specifications may be compromised
Solution Approach 1:
The system storage module pre-stores multiple groups of panel driving data corresponding to different display panel specifications during the manufacturing process. When the interface board is connected to a display panel, the system control module retrieves the appropriate panel data from storage and configures the driving parameters accordingly. This preliminary preparation of multiple data sets enables the standardized interface board to adapt to different specifications without requiring hardware changes or complex real-time adjustments.
