TFT Display Trim Lighting Structure for Vehicle Dashboard Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat, two-dimensional thin film transistor (TFT) displays in vehicle instrument panels lack aesthetic appeal compared to traditional three-dimensional gauges, necessitating an enhancement to create a perception of depth.
Innovation Solution
A light guide system comprising a base and a light distribution element, secured to the TFT display panel, which directs and transmits light from the periphery of the display to a spaced-apart location, creating a three-dimensional visual effect by emitting light between the operator and the display, thereby enhancing the perceived depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat TFT display is used, then the display can be programmed to show different features and has a compact structure, but the aesthetic appeal and perceived depth are reduced compared to traditional three-dimensional gauges
Solution Approach 1:
A light guide assembly is introduced as an intermediary component between the TFT display and the operator. This assembly includes a light guide member with a light guide face spaced from the display face, creating a visual intermediary space that produces trim lighting effects and enhances perceived depth while maintaining the programmable nature of the TFT display
Solution Approach 2:
The invention adds a spatial dimension by positioning the light guide face at a distance from the display face, creating depth in the z-direction. This dimensional addition transforms the flat two-dimensional display into a three-dimensional visual experience with trim lighting effects, without compromising the programmable functionality
2Shape
If a light guide system is added to create three-dimensional visual effect, then aesthetic appeal is improved, but device complexity increases
Solution Approach 1:
The light guide assembly serves multiple functions simultaneously: it creates the three-dimensional visual effect, provides trim lighting along the periphery, and enhances aesthetic appeal. By combining these functions into a single integrated assembly, the invention adds visual complexity without proportionally increasing overall device complexity
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 light guide system effectively adds a three-dimensional visual effect to the TFT display, improving its aesthetic appeal by emitting light at a position spaced apart from the display panel, enhancing the visual experience for vehicle operators.
Implementation Method 1
The guide structure can be configured to transmit light from the first display panel through the light guide to a surface of the guide structure spaced apart from the first display panel
Implementation Method 2
The base can be configured to direct light emitted by the display panel away from the display panel to the light distribution element

AI summary
The present teachings provide for a light guide for a vehicle dashboard display having a first display panel. The light guide can include a guide structure secured to the vehicle dashboard display proximate to the first display panel. The guide structure can be configured to transmit light from the first display panel at a first position, through the guide structure, to a second position spaced apart from the first display panel.
