Display Panel Control Elements for Full-Screen Front Camera Hiding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with front cameras are unable to implement full-screen display due to the reserved area for the camera.
Innovation Solution
A display panel with a first display portion containing light-emitting elements and control elements that can switch between light-transmissive and light-shielding states under electric field control, allowing the camera to be hidden during normal display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an area is reserved for the front camera on the display panel, then the camera can perform photographing functions, but full-screen display cannot be implemented
Solution Approach 1:
The patent applies the dynamics principle by making the control element switchable between different states. The control element can dynamically change from a light-shielding state (when camera photographing is needed) to a light-transmissive state (when full-screen display is needed), allowing the display area to be fully utilized while maintaining camera functionality.
Solution Approach 2:
The patent applies the local quality principle by making only the specific control element corresponding to the camera area switchable, while other display elements maintain their normal display properties. This allows the camera region to have different optical properties (light-shielding or light-transmissive) as needed, without affecting the rest of the display.
2Area of stationary object
If the control element is in the light-shielding state to hide the camera, then full-screen display is achieved, but ambient light cannot reach the camera for photographing
Solution Approach 1:
The control element is designed to be dynamically switchable between light-shielding and light-transmissive states based on operational requirements. When photographing is needed, it switches to light-transmissive state to allow ambient light to reach the camera; when display is prioritized, it switches to light-shielding state to achieve full-screen display effect.
Solution Approach 2:
The control element operates in periodic cycles, switching between light-shielding state during normal display periods and light-transmissive state during photographing periods. This periodic switching allows the system to alternate between full-screen display mode and camera photographing mode as needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables full-screen display by hiding the camera when not in use, while allowing ambient light to reach the camera for photographing purposes.
Implementation Method 1
the control element is configured to perform switching between a light-transmissive state and a light-shielding state under the control of an electric field
Implementation Method 2
the light-emitting element is configured to emit light under the control of a driving voltage
