Transparent Display Transparency Control for Content Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display apparatuses face challenges in effectively displaying information due to their transparency, which can hinder visibility of content behind the screen.
Innovation Solution
A display apparatus with variable transparency, equipped with sensors to detect proximity to entities and adjust transparency levels based on distance, allowing for dynamic adjustment of display settings to enhance content visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display maintains high transparency to allow background viewing, then background visibility is improved, but content visibility deteriorates
Solution Approach 1:
The display apparatus dynamically adjusts its transparency level based on the detected proximity of objects or users. When an object approaches within a threshold distance, the display switches from a transparent state to a less transparent state, and vice versa. This dynamic adjustment resolves the contradiction by making transparency adaptive rather than static, allowing the display to optimize for either background visibility or content visibility depending on real-time conditions.
Solution Approach 2:
The invention changes the transparency parameter of the display based on proximity detection. By using sensors to detect the distance of nearby objects and adjusting the transparency parameter accordingly (switching between first and second transparency levels), the system resolves the contradiction between maintaining background visibility and ensuring content visibility. The transparency parameter is modified from a fixed value to a condition-dependent variable.
2Ease of manufacture
If the display uses opaque semiconductor compounds for manufacturing, then manufacturing ease is improved, but transparency deteriorates
Solution Approach 1:
The invention changes the material parameter from opaque semiconductor compounds to transparent semiconductor compounds. This parameter change in material composition allows the display to achieve both manufacturability (using established semiconductor fabrication processes) and transparency (through the optical properties of transparent semiconductor materials), thereby resolving the contradiction between ease of manufacture and transparency.

AI summary
A display apparatus and a method thereof. The display apparatus includes a display with variable transparency, a sensor which senses a location of at least one of a person and an object, and a controller which determines proximity of the at least one of the person and the object to the display based on a result of the sensing by the sensor, and adjusts the transparency of the display differently according to a result of the determining. Accordingly, a user can easily recognize contents displayed on the display screen having high transparency in the display apparatus.
