Sliding Display Panel Mechanism for Under-Panel Light Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional pop-up camera design in display devices increases manufacturing costs and power consumption, making it difficult to meet the requirement of long battery life for full-screen designs.
Innovation Solution
A display device with a sliding mechanism that includes a middle frame, a display panel, and a light sensor, where a sliding key drives the display panel to slide relative to the middle frame, exposing or hiding the light sensor without the need for a drive motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a pop-up camera design is used to achieve full-screen design, then the display area is increased, but the manufacturing cost and power consumption increase due to the drive motor
Solution Approach 1:
The patent replaces the motor-driven mechanical system with a sliding mechanism that uses elastic potential energy stored in a spring. The sliding key slides along the side portion of the middle frame, utilizing the spring's elastic force to drive the display panel's movement, thereby eliminating the need for a continuous power supply and reducing overall power consumption while maintaining the full-screen display area.
Solution Approach 2:
The sliding mechanism is designed to be self-powered through the elastic potential energy stored in the spring. The spring automatically propels the sliding key to move the display panel between extended and retracted positions without requiring external power input, making the system self-service and energy-efficient.
2Area of stationary object
If a pop-up camera design is used to achieve full-screen design, then the display area is increased, but the manufacturing cost increases due to the drive motor
Solution Approach 1:
The patent replaces the complex motor-driven system with a simpler sliding mechanism comprising a sliding key, spring, and guide grooves. This substitution eliminates expensive motor components, reduces assembly complexity, and lowers manufacturing costs while achieving the same functional outcome of extending the display area.
Solution Approach 2:
The sliding mechanism uses simple, inexpensive components such as a spring, sliding key, and guide grooves that can be easily manufactured and assembled. These components are replaceable and do not require expensive motor assemblies, thereby reducing overall manufacturing costs.
3Use of energy by stationary object
If a sliding mechanism is used instead of a drive motor, then power consumption is reduced, but the device complexity changes
Solution Approach 1:
The sliding mechanism is segmented into distinct functional components: the sliding key for movement, the spring for energy storage and propulsion, and the guide grooves for directional control. This segmentation allows each component to perform its specific function efficiently, reducing overall complexity compared to a motor-driven system while maintaining low power consumption.

AI summary
A display device is provided. The display device includes a middle frame, a display panel, a light sensor, and a sliding mechanism. The light sensor is located under the display panel. The sliding mechanism includes a sliding key slidably assembled at a side portion of the middle frame. The sliding key passes through the side portion of the middle frame and is connected to the display panel. The sliding key drives the display panel to slide relative to the middle frame to control the display panel to block or expose the light sensor.
