Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in achieving rapid driving operations for multiple units in a unit array, leading to inefficiencies in frame period duration and signal attenuation issues.
Innovation Solution
The communication device employs a substrate with divided scan lines and data lines, utilizing a driving method that synchronously provides scan and data signals to units in sub-areas of the unit array, allowing for simultaneous row-by-row driving and alternating column driving to reduce frame period duration and improve signal integrity.

Engineering Contradiction Analysis
1Speed
If multiple units in the unit array are driven sequentially using conventional scanning methods, then the device complexity is reduced, but the frame period duration increases and response speed decreases
Solution Approach 1:
The scan lines are divided into multiple groups (first scan line group and second scan line group), allowing different groups to be driven by different scanning circuits simultaneously. This segmentation enables parallel driving of multiple units without requiring a single complex sequential driver, thus improving response speed while keeping individual driving circuits relatively simple.
Solution Approach 2:
Multiple scanning circuits are combined to work together on different scan line groups simultaneously. The first scanning circuit drives the first scan line group while the second scanning circuit drives the second scan line group, merging their capabilities to achieve faster overall response without requiring any single circuit to be overly complex.
2Area of stationary object
If the number of scan lines increases to cover more units, then the coverage area increases, but the signal attenuation becomes more severe
Solution Approach 1:
Scan lines are segmented into multiple groups that can be driven by separate scanning circuits. This segmentation allows each circuit to drive a smaller subset of scan lines, reducing the total length and resistance of individual scan line paths, thereby mitigating signal attenuation while still covering a large overall area through coordinated operation of multiple circuits.
Solution Approach 2:
Multiple scanning circuits act as intermediaries to drive different portions of the scan lines. Instead of using a single long scan line that suffers from attenuation, the signal is distributed through multiple intermediate circuits that each drive shorter scan line segments, reducing the attenuation effect in each segment.
3Duration of action of moving object
If conventional sequential driving methods are used, then the device structure remains simple, but the frame period duration becomes excessively long
Solution Approach 1:
The scanning function is segmented across multiple scanning circuits, each responsible for driving specific scan line groups. This allows simultaneous operation of multiple circuits to reduce the overall frame period duration, while each individual circuit maintains a relatively simple structure by handling only a subset of scan lines.
Solution Approach 2:
The driving approach transitions from a single-dimensional sequential scan to a multi-dimensional parallel scanning architecture. Multiple scanning circuits operate in parallel on different scan line groups, adding a temporal dimension of simultaneity to the driving process, thereby reducing frame period duration without requiring any single circuit to become overly complex.
