Mobile Phone Interface for External High-Resolution Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile information communication devices, such as mobile telephone units, face limitations in displaying web pages and TV programs due to their small screen size and resolution, leading to inefficient resource use and overlapping investments when trying to access full-screen content intended for larger devices like PCs or TVs.
Innovation Solution
A mobile information communication apparatus with an interface means that allows for the connection to a larger-screen external display device, enabling the display of higher-resolution images by sending external display signals, thus avoiding the need for special display data generating means and reducing overlapping investments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a mobile information communication apparatus uses its own attached display means, then portability is maintained, but screen size and resolution are constrained
Solution Approach 1:
The patent introduces an external display device as an intermediary between the mobile information communication apparatus and the user's visual perception system. The mobile apparatus connects to the external display via interface means, allowing high-resolution content to be displayed externally while the mobile device itself remains compact and portable. This mediator approach resolves the contradiction by separating the display function from the mobile device body.
2Adaptability or versatility
If a mobile information communication apparatus displays web pages with full-spec HTML, then browsing capability is improved, but screen resolution limitations prevent proper display
Solution Approach 1:
The patent extends the display dimension from the mobile device's limited built-in screen to an external display device with higher resolution capabilities. By moving the display function to another dimension (external space), the system can render full-spec HTML web pages with proper resolution while the mobile device itself remains small. This dimensional extension resolves the contradiction between browsing capability and display resolution.
3Adaptability or versatility
If a mobile information communication apparatus is equipped with special display data generating means for external displays, then external display capability is improved, but device complexity increases
Solution Approach 1:
The patent makes the mobile information communication apparatus's data processing means perform multiple functions: it processes data for both the built-in display and the external display device. The same data processing unit generates display data that can be output to either display target, eliminating the need for separate special-purpose processing hardware. This universal approach reduces system complexity while maintaining external display capability.
4Manufacturing precision
If a mobile information communication apparatus connects to external display devices, then display resolution is improved, but resource wastage occurs due to overlapping investments
Solution Approach 1:
The patent merges the data processing functions for the built-in display and external display into a single unified data processing means. Instead of maintaining separate processing chains, the system combines these functions, allowing the mobile apparatus to efficiently generate display data that can be routed to either display target without duplicating processing resources. This merging eliminates overlapping investments and improves resource efficiency.

AI summary
To display, on an external display device, an image with a higher resolution than a screen's resolution of a display belonging to a mobile information communication apparatus. This is achieved only by additionally providing an interface means between the external display device and the mobile information communication apparatus and further additionally providing some functions to a display data generating means originally belonging to the mobile information communication apparatus.A mobile information communication apparatus comprising a data processing means for sending plotting command/data to a display control means that controls the pixels of a display panel belonging to the mobile information communication apparatus; wherein an interface means is provided which receives the plotting command/data generated by the data processing means and sends, based on plotting command/data, an external display signal to the external display device; and wherein the data processing means and the interface means are configured to send, from the interface means, a higher-resolution external display signal.
