Reflective Display Light Distribution via Inclined Cover Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reflective display apparatuses often suffer from non-uniform lighting and insufficient brightness due to limitations in the installation of illuminating apparatuses, leading to poor display effects.
Innovation Solution
A reflective display apparatus comprising a reflective display panel, a transparent cover plate with an air gap, and a light source where the light source is positioned between the panel and the cover plate, with the cover plate inclined at an angle and light emitting elements having optical axes parallel to the panel, ensuring uniform light reflection and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an illuminating apparatus is directly used as a display light source for a reflective display apparatus, then the installation is simple and flexible, but non-uniform lighting areas and insufficient brightness occur easily
Solution Approach 1:
A transparent cover plate is introduced as an intermediary component between the light source and the display panel. The cover plate reflects light from the light source onto the display panel, creating a more uniform lighting distribution. This mediator structure allows the system to maintain installation flexibility while achieving uniform illumination across the display surface.
2Volume of moving object
If the transparent cover plate is positioned close to the reflective display panel, then the structure is compact, but the light reflection path is insufficient
Solution Approach 1:
The light path is extended by utilizing the vertical dimension between the cover plate and display panel. By positioning the light source and cover plate at a specific distance from the panel, the light can travel a longer path and undergo multiple reflections, improving light distribution uniformity without significantly increasing the overall device volume.
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
This configuration enhances display brightness and achieves a uniform display effect by reflecting light from the cover plate to the panel, improving illumination uniformity and overall display quality.
Implementation Method 1
the light emitted by the light source may be uniformly reflected to the reflective display panel through the transparent cover plate
Data Source
AI summary
A reflective display apparatus including a reflective display panel, a transparent cover plate, and a light source is provided. The transparent cover plate is disposed on one side of the reflective display panel. An air gap exists between the reflective display panel and the transparent cover plate. The light source is disposed between the reflective display panel and the transparent cover plate, and a light emitted by the light source travels towards the air gap before irradiating the transparent cover plate or the reflective display panel.
