Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with V-By-One (VBO) signal transmission interfaces, errors occur when a single VBO input loses transmission frequency or when lockup frequencies of multiple VBO inputs are unsynchronized, leading to inaccurate data transmission.
Innovation Solution
The implementation of a circuitry with multiple VBO inputs that includes a circuit board with a VBO output sending clock and data signals, and a controlling board with VBO inputs, utilizing n-type metal oxide semiconductor (NMOS) transistors and switches to manage signal frequencies, ensuring accurate data transmission by distinguishing between high and low frequency signals to lock and unlock transmission frequencies.

Engineering Contradiction Analysis
1Device complexity
If multiple VBO inputs are directly connected to the VBO output through resistors, then the circuit structure is simple, but transmission frequency synchronization errors occur when one input loses lock or inputs have unsynchronized frequencies
Solution Approach 1:
The patent introduces an intermediary circuit between the VBO inputs and output that includes frequency detection components and control logic. This intermediary structure monitors the frequency state of each VBO input and controls the transmission accordingly, preventing synchronization errors while maintaining reasonable circuit complexity.
Solution Approach 2:
The patent implements a feedback mechanism where the state of each VBO input (locked or unlocked) is detected and fed back to control the transmission. When any input is in an unlocked state, the system receives high-frequency signals and prevents data transmission, ensuring synchronization reliability.
2Productivity
If the VBO output sends clock signals to all VBO inputs simultaneously, then data transmission speed is high, but errors occur when inputs have unsynchronized lockup frequencies
Solution Approach 1:
The patent performs preliminary frequency detection and validation before enabling data transmission. The system checks whether all VBO inputs have synchronized lockup frequencies and are in a locked state before allowing the VBO output to transmit data signals, preventing transmission errors.
Solution Approach 2:
The patent applies preliminary anti-action by detecting unsynchronized states and preventing transmission before errors can occur. When frequency synchronization is detected as inadequate, the system actively prevents data transmission by maintaining high-frequency signal reception state, avoiding the propagation of erroneous data.
3Measurement precision
If the system uses high-frequency lockup signals to indicate unlocked state, then frequency differentiation is clear, but transmission errors occur when one input loses frequency while others remain synchronized
Solution Approach 1:
The patent merges the frequency detection and transmission control functions into a unified system. All VBO inputs are monitored collectively, and the transmission decision is made based on the combined state of all inputs, ensuring that transmission frequency consistency is maintained across the entire system.
