Solution Overview

Problem

Existing display devices in vehicles, such as head-up displays and dashboards, utilize different backlight sources, leading to excessive space consumption and inefficiency.

Innovation Solution

A display device comprising a first and second display panel forming an inclining angle with light-receiving surfaces, and a light-emitting module that emits light into a light-emitting space to create two images, one displayed on the first panel and another projected onto a windshield surface, optimizing space usage and information delivery to the driver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate backlight sources are used for head-up display and dashboard, then display functions are achieved, but space consumption increases

Engineering Contradiction:

Improvedisplay functionVSAvoidspace consumption

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines the head-up display and dashboard into a single integrated display device that uses one backlight source to illuminate both display panels simultaneously, thereby reducing space consumption while maintaining both display functions

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single backlight source is designed to serve multiple functions by illuminating both the first display panel (for head-up display) and the second display panel (for dashboard), making one component universal for multiple display purposes

Inventive Principle:

Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution allows for the simultaneous display and projection of high-quality images, enhancing driver information while reducing space occupancy in vehicles, by using liquid crystal panels and light-emitting diodes to control light transmission and projection effectively.

Implementation Method 1

The light-emitting module emits an illuminating light into the light-emitting space such that a part of the illuminating light forms a first image through the first display panel, and another part of the illuminating light passes through the second display panel and is projected onto a display surface to form a second image

AI summary

A display device and a vehicle are provided. The display device includes a first display panel, a second display panel and a light-emitting module. The first display panel includes a first side and a first light-receiving surface. The second display panel includes a second side and a second light-receiving surface. The first side is connected to the second side such that the first display panel and the second display panel form an including angle, and the first light-receiving surface and the second light-receiving surface form a light-emitting space. The light-emitting module is disposed corresponding to the light-emitting space. The light-emitting module emits an illuminating light into the light-emitting space such that a part of the illuminating light forms a first image through the first display panel, and another part of the illuminating light passes through the second display panel and is projected onto a display surface where it forms a second image.
