Rotating Camera Module Avoiding Display Self-Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to prevent a portion of the display device from being captured by the camera without increasing the protruding height of the camera module, particularly in ultra-high-definition display devices with increased thickness due to more light emitting diodes.
Innovation Solution
A camera module that rises vertically and rotates at a predetermined angle when a predetermined pressure is applied, allowing it to protrude towards the front surface of the display device without increasing its height, using a mechanism involving a case member, a guide member, and elastic members to facilitate this movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the protruding height of the camera module is increased to prevent the display device from being captured, then the camera can avoid taking the display device in its angle of view, but the appearance of the display device is deteriorated and the thickness is excessively increased
Solution Approach 1:
The camera module is designed to dynamically change its protruding height based on operational needs. When a predetermined pressure is applied, the camera module protrudes by a predetermined height to position the camera away from the display device surface, preventing the display device from being captured. When no pressure is applied, the camera module retracts to maintain a sleek appearance. This dynamic adjustment resolves the contradiction between avoiding self-capture and maintaining aesthetic appearance.
Solution Approach 2:
Instead of solely increasing the protruding height in the vertical dimension, the invention introduces a rotational dimension. The camera module can rotate at a predetermined angle when pressure is applied, changing the orientation of the camera relative to the display device surface. This angular adjustment allows the camera to avoid capturing the display device without requiring excessive vertical protrusion, thereby maintaining a thinner profile.
2Object-affected harmful factors
If the protruding height of the camera module is increased to prevent the display device from being captured, then the camera can avoid taking the display device in its angle of view, but the thickness of the display device is excessively increased
Solution Approach 1:
The camera module transitions from a static to a dynamic structure that can extend and retract. During normal operation, the camera module remains retracted to minimize the overall thickness of the display device. When imaging is required, it protrudes only when needed, reducing the average thickness while still preventing self-capture when the camera is active.
Solution Approach 2:
The invention adds rotational movement as another dimension of adjustment. By enabling the camera module to rotate at a predetermined angle in addition to protruding, the system achieves effective avoidance of self-capture with reduced vertical displacement. This angular adjustment allows the camera to point away from the display device surface without requiring the same degree of vertical protrusion that would increase thickness.
3Length of stationary object
If the camera module is made retractable to reduce protruding height, then the appearance is improved and thickness is reduced, but the camera cannot effectively avoid capturing the display device
Solution Approach 1:
The retractable camera module is equipped with pressure-sensitive activation. When a predetermined pressure is applied (indicating imaging need), the camera module automatically protrudes by a predetermined height and rotates at a predetermined angle. This dynamic response ensures that the camera achieves the necessary positioning to avoid capturing the display device only when imaging operations are performed, while maintaining a low-profile appearance during non-operational states.
Solution Approach 2:
The camera module incorporates self-actuating mechanisms that respond automatically to applied pressure. The pressure-sensitive structure triggers the protrusion and rotation movements without requiring external control systems. This self-service capability ensures reliable avoidance of self-capture through automatic positional adjustment when imaging is initiated, while maintaining minimal protrusion during normal states.

AI summary
A display device including a camera module is disclosed. The display device includes a display panel; a case member disposed on a back surface of the display panel; and a camera module disposed on a back surface of the case member. When a predetermined pressure is applied to an upper part of the camera module, the camera module is configured to rise by a predetermined height and then rotate at a predetermined angle.
