Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display devices lack an efficient method for users to input text and image data, leading to inconvenience when using diverse functions and applications, especially in digital broadcasting environments where two-way communication and EPG services are prevalent.
Innovation Solution
A method and device for easy text and image data input on image display devices, enabling users to input text through a text input window and select/display image data on a message input window, using a combination of user interface elements like touch screens and remote controllers, with support for EPG information and network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional input methods are used in image display devices, then device complexity is reduced, but ease of operation deteriorates when inputting text or images
Solution Approach 1:
The patent introduces an image display device as an intermediary between broadcast signals and user interaction. The device includes a display unit showing broadcast content and an input interface that receives user inputs (text or image data), processes them, and transmits to external devices, mediating the communication without requiring complex user-side equipment
Solution Approach 2:
The image display device performs multiple functions: displaying broadcast programs, receiving user inputs through various interfaces (remote controller, touchscreen), processing text and image data, and transmitting to external devices. This multi-functionality consolidates what would otherwise require separate devices into one universal platform
2Ease of operation
If adequate user input means are provided, then ease of operation improves, but device complexity increases
Solution Approach 1:
The input system is segmented into distinct components: a display unit for showing content, an input interface (separate remote controller or integrated touchscreen) for receiving data, a processing unit for handling text/image inputs, and a transmission unit for sending to external devices. This segmentation allows each component to be optimized independently while maintaining overall simplicity
Solution Approach 2:
The image display device autonomously processes user inputs without requiring external processing equipment. The device itself handles text input through on-screen keyboards, image capture through integrated cameras or sensors, data processing, and transmission, making the system self-sufficient and reducing overall complexity

AI summary
The present invention relates to a method for inputting characters on an image display device and an image display device employing the method, and more specifically, to a method for inputting characters on an image display device that displays a character input window for data input when a data input request is received while outputting preset contents, and sets a character input mode and inputs a preset character that corresponds to a character input signal on the character input window, and an image display device employing the method.
