Solution Overview

Problem

Conventional screen display methods burden the host by processing image signals, which can lead to increased processing demands and inefficiencies, particularly in network game environments where precise operations are required.

Innovation Solution

A display system comprising a host and a display device connected via a wireless or wired method, where the display device processes and enlarges local portions of the frame, reducing the host's burden and allowing for finer operations without affecting remote displays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the host processes the image signal to enable local portion enlargement, then the display functionality is improved, but the processing burden on the host increases

Engineering Contradiction:

Improvedisplay functionalityVSAvoidprocessing burden

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the image signal processing function from the host and relocates it to the display device. The host only transmits the original image signal without processing, while the display device performs the local portion enlargement processing independently, thereby reducing the host's processing burden while maintaining enhanced display functionality

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary approach where the display device acts as a processing intermediary between the host and the final display output. The display device receives the original image signal from the host and performs intermediate processing (local enlargement) before displaying, thus distributing the processing workload

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the host transmits processed image signals, then the display precision is improved, but the transmission data volume increases

Engineering Contradiction:

Improvedisplay precisionVSAvoidtransmission data volume

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary control information (enlargement region coordinates, enlargement ratio) from the processed image signal and transmits it separately, while the original image signal is transmitted in its unprocessed form. This reduces the transmission data volume while maintaining the capability to achieve precise local enlargement display

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the image signal transmission into two parts: the original image signal transmitted at full resolution, and separate control parameters (enlargement region, magnification ratio) transmitted independently. This segmentation allows the display device to perform selective processing without transmitting unnecessarily large amounts of processed data

Inventive Principle:

Principle #1Segmentation

AI summary

A display system includes a display device and a host. The host is separately disposed on the display device and connected to the display device through a wireless or wired manner. The host transmits an image signal to the display device. The display device is configured to display a frame according to the image signal and enlarge a local portion of the frame.
