Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display (LCD) devices, the simple structure makes it difficult to efficiently supply and compensate the pixel voltage, leading to distortion of the common voltage and deterioration of image quality.
Innovation Solution
A flexible member is designed with a flexible film, data leads, application leads, and feedback leads to efficiently supply and compensate the common voltage to the liquid crystal display panel, including a driving chip and gate leads connected to the gate line and data line, allowing for multiple voltage supply paths and feedback mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the structure of LCD device is simplified, then manufacturing cost is reduced, but it becomes difficult to provide the flexible member with an arrangement for supply and compensation of the pixel voltage
Solution Approach 1:
The patent combines multiple functions into a single flexible member structure. The flexible member integrates both the application leads for supplying common voltage and the feedback leads for compensating pixel voltage, eliminating the need for separate compensation circuits. This merging approach simplifies the overall device structure while maintaining both voltage supply and compensation capabilities, directly resolving the contradiction between simplified structure and functional completeness.
Solution Approach 2:
The flexible member is designed with multi-functionality, serving both as a voltage supply pathway and a feedback pathway. The application leads and feedback leads are both formed on the same flexible member, allowing it to perform multiple functions simultaneously. This universal design enables the flexible member to handle both common voltage supply and pixel voltage compensation without requiring additional separate structures.
2Productivity
If the flexible member provides multiple voltage supply paths, then common voltage supply efficiency is improved, but the structure of the flexible member becomes more complex
Solution Approach 1:
The flexible member is segmented into distinct functional regions: application leads for voltage supply and feedback leads for compensation. Each segment performs a specific function, with the application leads providing multiple parallel pathways for common voltage supply to improve efficiency, while the feedback leads handle compensation signals. This segmentation allows multiple voltage paths without creating overall structural complexity.
