Solution Overview
Problem
Current display systems face increased costs and image errors when trying to display multiple video data sets on a single panel, as they require complex circuitry for superimposing images and are prone to errors if one data set malfunctions.
Innovation Solution
A video data display device with multiple driving circuits, each equipped with a status controller, data receiver, and output buffer, which allows for direct processing and synchronization of multiple video data sets, reducing the need for additional superimposition circuits and enabling reactive error handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple video data sets are superimposed in the image processor or timing controller to display on a single panel, then the display system can show multiple video contents, but the cost of the display system increases due to additional processing circuits
Solution Approach 1:
The patent divides the display system into multiple independent driving circuits, each responsible for processing one video data set. Each driving circuit independently drives a corresponding region of the display panel, eliminating the need for complex superimposition circuits in the image processor or timing controller. This segmentation approach maintains the ability to display multiple video contents while significantly reducing system complexity and cost.
2Measurement precision
If multiple video data sets are superimposed to combine images, then the resolution of the display signal is higher, but the data amount of display signals to be processed by the driving circuit increases, further increasing cost
Solution Approach 1:
The display panel is divided into multiple independent display regions, with each driving circuit responsible for a specific region and its corresponding video data set. This segmentation ensures that each driving circuit processes only the data required for its region, maintaining high resolution without increasing the data processing burden on individual circuits or overall system cost.
3Adaptability or versatility
If multiple video data sets are superimposed to combine images, then the display system can show multiple contents, but when any video data set malfunctions, the superimposition process is prone to errors causing incorrect image information to be displayed
Solution Approach 1:
By dividing the display system into independent driving circuits, each handling a separate video data set and display region, the patent isolates potential errors. If one video data set malfunctions, only the corresponding driving circuit and display region are affected, while other regions continue to display correctly. This eliminates the error propagation issue inherent in superimposition-based systems.
Solution Approach 2:
The patent incorporates a status controller that receives status information from each driving circuit and generates control signals based on the operational state of each circuit. This feedback mechanism enables real-time monitoring and error detection, allowing the system to respond to malfunctions in individual video data sets or driving circuits, thereby maintaining display accuracy and reliability.
Data Source
AI summary
The present invention discloses a video data display device including a plurality of driving circuit. Each driving circuit includes a status controller, a data receiver, an output data generation unit, and an output buffer. The status controller couples with the data receiver, the output data generation unit, and the output buffer. The status controller generates a status signal based on the operation information of the data receiver, the output data generation unit, or the output buffer. The status controller transmits the status signal to the status controller of other driving circuits.
