Serial Parameter Propagation for Splicing Screen Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional splicing screens require manual setting operations for each light box, which is time-consuming and prone to errors due to electrostatic discharge (ESD), especially in large-scale high-resolution displays.
Innovation Solution
A screen control method and system where a first serial unit receives a parameter, performs setting, calculates a second parameter, and transmits it to a second serial unit, allowing automatic parameter propagation throughout the system, reducing the need for manual input and minimizing maintenance time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual setting operations are used for each light box, then the splicing screen can be controlled, but the setup time is excessively long and error-prone
Solution Approach 1:
The patent segments the parameter setting process by dividing the splicing screen into multiple light boxes, each with its own controller. The first light box receives parameters from the video source and automatically generates parameters for subsequent light boxes, eliminating the need for manual setting of each unit and dramatically reducing setup time.
Solution Approach 2:
The first light box performs preliminary action by receiving the original parameters from the video source and pre-calculating the parameters needed for all subsequent light boxes. This preliminary parameter generation and propagation eliminates the need for manual configuration of each light box during setup.
2Reliability
If manual commands are input for each light box, then the display can be configured, but electrostatic discharge may erroneously modify setting values
Solution Approach 1:
The system implements self-service by enabling the first light box to automatically generate and transmit parameters to subsequent light boxes without manual intervention. This automated parameter propagation eliminates human interaction with the setting process, preventing ESD from affecting manual command input and ensuring accurate setting values.
Solution Approach 2:
The patent replaces the mechanical/manual command input system with an automated electronic parameter generation and transmission system. The first light box's controller automatically calculates and transmits parameters through the serial communication interface, substituting manual operations that are vulnerable to ESD interference.
3Ease of repair
If a new light box replaces a damaged one, then the display can be restored, but manual setup is required again
Solution Approach 1:
The first light box performs preliminary parameter generation for all light boxes in the system. When a new light box replaces a damaged one, it automatically receives the pre-calculated parameters from the first light box through serial communication, eliminating the need for manual re-setup and enabling rapid replacement.
Solution Approach 2:
The parameter propagation system provides self-service by automatically delivering the correct parameters to any light box in the sequence. When a new light box is installed, it automatically receives its configuration parameters from the first light box without requiring manual intervention, significantly reducing repair time.
4Manufacturing precision
If high resolution splicing screen is constructed with many light boxes, then display quality improves, but setup complexity increases
Solution Approach 1:
The patent segments the high-resolution display into multiple light boxes while simplifying the configuration process. Each light box is an independent unit with its own controller, but the parameter segmentation and automatic propagation eliminate the complexity of configuring each unit manually, allowing high resolution without proportional increase in setup complexity.

AI summary
The present invention provides a method of transmitting parameters for controlling a display screen of a screen control system. The method is used in a first serial unit of the screen control system, and includes steps of: receiving a first parameter; performing parameter setting on the first serial unit according to the first parameter; calculating a second parameter according to the first parameter, wherein the second parameter is different from the first parameter; and transmitting the second parameter to a second serial unit of the screen control system.
