Solution Overview
Problem
Traditional display systems with integrated hosts and display screens occupy excessive space and incur high costs due to thick transmission cables, which also lead to signal energy weakening over long distances.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transmission channels are designed in a transmission cable to support high picture quality and high resolution, then the efficiency of signal transmission is improved, but the volume of the transmission cable increases
Solution Approach 1:
The patent divides the transmission system into multiple independent transmission channels within the cable, each carrying specific signal components (video signals, timing control signals, power signals). This segmentation allows efficient signal transmission while organizing channels systematically to manage cable volume.
Solution Approach 2:
The patent transitions from single-channel transmission to multi-channel transmission by adding spatial dimension (multiple channels) to the transmission system. This enables parallel transmission of multiple signal types simultaneously, improving overall transmission efficiency without requiring excessively thick single-channel cables.
2Ease of operation
If the transmission cable is made excessively long to allow flexible placement, then the ease of operation is improved, but signal energy weakening occurs during signal transmission
Solution Approach 1:
The patent introduces a power signal transmission channel as an intermediary to provide power to the display device remotely. This allows the display device to be placed far from the host without signal energy weakening, as the power channel compensates for energy loss over long distances.
Solution Approach 2:
The transmission cable is designed as a composite structure containing multiple types of conductors (signal conductors, power conductors) with different functions. This composite design enables the cable to simultaneously transmit weak signal data and strong power signals over long distances, maintaining signal energy and enabling flexible placement.
3Device complexity
If the host and display screen are arranged in the same enclosure, then the device complexity is reduced, but the volume of the display system increases
Solution Approach 1:
The patent segments the display system into separate functional modules: the host (processing device) and the display device (screen), connected via a multi-channel transmission cable. This segmentation reduces the overall system volume by allowing compact placement of each module while maintaining functional integration through the transmission channels.
Solution Approach 2:
The transmission cable acts as an intermediary that connects the separated host and display device, enabling them to function as an integrated system despite physical separation. This intermediary connection allows the system to maintain low complexity while achieving reduced volume through spatial separation of components.

AI summary
A split-type display system includes a processing device, a display device, and a transmission cable connecting the processing device and the displaying device. The processing device includes a processing unit, a first and a second conversion unit. The display device includes a third and a fourth conversion unit, and a display unit. The processing unit generates a first image signal and a first timing control signal. The first and the second conversion units, respectively, converts the first image signal and the first timing control signal into a second image signal and a second timing control signal. The third and the fourth conversion units, respectively, receive and convert the second image signal and the second timing control signal into a third image signal and a third timing control signal. The display unit displays the third image signal according to the third timing control signal.
