Rollable Display Controller Adjusting Size for Power and Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display apparatuses face challenges in reducing power consumption and aesthetics due to their increasing size, as larger displays consume more power and appear less aesthetically pleasing when not in use.
Innovation Solution
An image display apparatus with a rollable display, a drive unit, and a controller that adjusts the display's size or height based on the attributes of the content to be displayed, using a rollable display mechanism and motor-driven roller to roll up or down the display, allowing for size adjustments according to content requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display size is increased to provide better viewing experience, then the viewing quality is improved, but the power consumption increases
Solution Approach 1:
The display size is made dynamic and adjustable rather than fixed. The rollable display can be expanded or contracted based on usage requirements, allowing the system to optimize between viewing quality and power consumption by adapting the display size to actual needs.
Solution Approach 2:
The physical parameter of display size is changed dynamically through the rolling mechanism. By altering the extended length of the rollable display, the system can adjust power consumption while maintaining adequate viewing quality for different scenarios.
2Illumination intensity
If the display size is increased to provide better viewing experience, then the viewing quality is improved, but the aesthetics deteriorates when not in use
Solution Approach 1:
The display transitions between extended and retracted states dynamically. When not in use, the display can be rolled up to minimize its visual presence and improve aesthetics, while still providing full viewing quality when needed.
Solution Approach 2:
The display is segmented into arollable portion and a fixed portion, allowing the functional display area to be separated from the permanent installation structure. This enables the display to be concealed when not in use while maintaining aesthetic appearance.
3Area of stationary object
If the display size is increased, then the viewing area is improved, but the device complexity increases
Solution Approach 1:
The rollable display is nested within a housing or mounting structure. The flexible display panel is rolled around a cylindrical roller that is housed within the device casing, creating a compact configuration when retracted and an expanded configuration when deployed.
Solution Approach 2:
The display area is extended in one dimension (length) through the rolling mechanism rather than increasing complexity in multiple dimensions. This allows for a large display area to be achieved through linear extension rather than volumetric expansion.

AI summary
An image display apparatus can include a rollable display; a drive part configured to roll up or roll down the rollable display; a user input interface configured to receive a signal from a remote controller; and a controller configured to set the image display apparatus in a standby mode having the rollable display in a non-viewable retracted, in response to receiving a user input signal from the remote controller, transition the rollable display from the non-viewable retracted state to a partial view state having a first height and display at least one object on the rollable display, and in response to receiving a voice input while in the partial view state, transition the rollable display from the partial view state to a main view state having a second and display a content item corresponding to the voice input.
