Display Panel Driving Method for Mode Switching Stability

Solution Overview

Problem

Existing display panel driving methods face challenges in efficiently switching between different display modes, leading to issues such as lagging of the counting unit and abnormal displaying due to incomplete mode switching.

Innovation Solution

A driving method that enters a non-counting state when receiving a display mode switching startup instruction, allowing the display panel to display a first set picture while switching to a target display mode, and then enters a counting state upon receiving a data mode switching completing instruction, enabling accurate counting and preventing lagging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the counting unit continues to count during display mode switching, then the counting function remains continuous, but the counting unit lags and abnormal displaying occurs due to incomplete mode switching

Engineering Contradiction:

Improvedisplay stabilityVSAvoidcounting unit lag

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pausing the counting function before mode switching occurs. The counting unit is instructed to pause counting in advance during the mode switching period, ensuring that counting operations do not interfere with the switching process. After switching completes, the counting unit resumes counting, thus preventing lag and abnormal displaying while maintaining continuous counting functionality.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the display panel switches between different display modes, then display versatility is improved, but the switching process causes counting unit lag and display abnormalities

Engineering Contradiction:

Improvedisplay mode switchingVSAvoiddisplay stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an intermediary mechanism (the pause instruction for the counting unit) that mediates between the mode switching operation and the counting function. During mode switching, the counting unit receives a pause instruction from the processor, acting as an intermediary control signal that temporarily suspends counting operations. This prevents conflicts between switching and counting, ensuring display stability while allowing versatile mode switching.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If the counting unit operates continuously during mode switching, then counting precision is maintained, but mode switching completeness is compromised leading to abnormal displaying

Engineering Contradiction:

Improvecounting accuracyVSAvoidmode switching completeness

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent applies preliminary action by pausing the counting function before mode switching occurs. The counting unit is instructed to pause counting in advance during the mode switching period, ensuring that counting operations do not interfere with the switching process. After switching completes, the counting unit resumes counting, thus preventing lag and abnormal displaying while maintaining continuous counting functionality.
