Shared-Backlight Dual-Resolution Display for Compact Game Machines

Solution Overview

Problem

Multiple backlight modules in dual displays increase the size and weight of electronic game machines, hindering the achievement of lightweight, thin, and compact designs.

Innovation Solution

A dual resolution display with a shared backlight module that provides a common backlight source to two displays with different resolutions, reducing the need for separate modules and optimizing space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate displays with individual backlight modules are installed on the electronic game machine, then different picture contents can be displayed simultaneously to boost entertaining effects, but the volume and weight of the machine increase

Engineering Contradiction:

Improvedisplay functionalityVSAvoidmachine volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent merges multiple display units (first display and second display) with different resolutions into a single integrated display structure that shares a common backlight module. This combining approach allows the system to provide multiple display functions simultaneously while avoiding the volume penalty of separate backlight modules for each display unit.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shared backlight module serves multiple functions by providing illumination to both the first display and the second display simultaneously. This universal lighting component enables the system to support multiple display resolutions and picture content types without requiring dedicated backlight modules for each display function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate displays with individual backlight modules are installed on the electronic game machine, then different picture contents can be displayed simultaneously to boost entertaining effects, but the weight of the machine increases

Engineering Contradiction:

Improvedisplay functionalityVSAvoidmachine weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The patent merges multiple display units (first display and second display) with different resolutions into a single integrated display structure that shares a common backlight module. This combining approach allows the system to provide multiple display functions simultaneously while avoiding the volume penalty of separate backlight modules for each display unit.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shared backlight module serves multiple functions by providing illumination to both the first display and the second display simultaneously. This universal lighting component enables the system to support multiple display resolutions and picture content types without requiring dedicated backlight modules for each display function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Volume of moving object

If a single shared backlight module is used to illuminate both first display and second display, then the installation space and weight are reduced, but the complexity of signal allocation and display resolution management increases

Engineering Contradiction:

Improveinstallation spaceVSAvoidsignal processing complexity

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent segments the signal processing path by introducing separate signal conversion modules for each display unit. The first display signal conversion module converts signals for the first display, while the second display signal conversion module handles the second display. This segmentation allows independent resolution management (first display resolution and second display resolution) while sharing the common backlight module.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The signal conversion modules act as intermediaries between the input display signals and the respective display units. These intermediaries manage the complexity of resolution conversion and signal allocation, enabling the shared backlight module to serve multiple displays with different resolutions without overwhelming complexity in the main signal path.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A dual resolution display with a shared backlight, including: a decorative panel having a first surface and second surface opposite to the first surface; a backlight module fixed on the second surface of the decorative panel; a first display, disposed between the decorative panel and the backlight module, is configured to display picture content with a first display resolution according to a first display resolution signal; and a second display, adjacent to the first display, the second is configured to display picture content with a second display resolution according to a second display resolution signal. The backlight module provides a blacklight source to the first display and the second display, and the first display and the second display respectively expose a first display area and a second display area on the first surface of the decorative panel. The display area is used to display picture content with different resolutions.
