Motorized Display Exposure Control for Space-Efficient Content Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices expose all areas of the display regardless of usage, wasting space when not in use and consuming unnecessary power due to constant exposure.
Innovation Solution
A display device equipped with a motor that selectively exposes all or part of the display area based on received content, controlled by a controller to adjust the display size according to image size, content type, and user interaction, using a communication module for external terminal interaction.

Engineering Contradiction Analysis
1Ease of operation
If the display area is always exposed, then the user can view content at any time, but space is wasted when the display is not in use
Solution Approach 1:
The display area is made dynamically adjustable through a motor-driven mechanism that can change the exposed area size between full exposure and partial exposure states, allowing the system to adapt to different usage scenarios and optimize both space utilization and content viewing availability
Solution Approach 2:
The physical parameter of the exposed display area is changed based on operational needs - the motor adjusts the display area exposure level according to whether content is being viewed or the device is in idle state, optimizing the balance between accessibility and space efficiency
2Ease of operation
If the display area is always exposed, then content is always accessible, but power is consumed unnecessarily when not in use
Solution Approach 1:
The display area exposure operates periodically based on usage patterns - the motor adjusts the display between fully exposed during active content viewing and partially exposed during idle periods, creating a rhythmic on-demand operation that reduces unnecessary power consumption while maintaining content accessibility when needed
3Area of stationary object
If a motor is added to adjust display area, then space utilization is improved, but power consumption increases
Solution Approach 1:
The motor-driven display area adjustment system operates autonomously based on detected usage states - the controller automatically activates the motor to adjust the display exposure level according to whether content is being viewed or the device is idle, eliminating the need for manual intervention and optimizing the balance between space utilization and energy consumption
4Area of stationary object
If the display area is reduced to partial exposure, then space efficiency is improved, but the user cannot view content in full resolution
Solution Approach 1:
The display area exposure is dynamically adjusted based on content type and usage scenario - the motor transitions the display between full exposure for high-quality content viewing and partial exposure for space optimization, with the controller intelligently determining the appropriate exposure level to maintain content quality when needed

AI summary
Provided in one embodiment of the present invention is a display device comprising: a communication unit for communicating with an external terminal; a display including a display area for outputting content; a motor for controlling the display so that an area of the display area is exposed to the outside; and a control unit for controlling the communication unit, the display, and the motor, wherein the control unit performs mirroring with the external terminal, receives at least one image from the external terminal, determines the size of the area exposed to the outside on the basis of the size of the received image, and outputs the received image in the area, the state in which the display area is maximally exposed to the outside is defined as a full view, and the state in which a first area of the display area is exposed to the outside is defined as a partial view.
