Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch screen or hole-punch screen is used to accommodate the front-facing camera, then the camera can be integrated into the display, but the display area is reduced and display quality is affected
Solution Approach 1:
The display screen is designed with a deformable region that can dynamically change its state between flat and bent. When bent, the display screen creates a step structure that allows the front-facing camera to be positioned below the display surface, thereby maintaining the full display area without notches or hole-punches while still accommodating the camera module.
2Area of stationary object
If an under-display camera is used, then the display area is maintained, but the light transmittance requirement reduces the number of display components and affects display quality
Solution Approach 1:
Instead of using an under-display camera that requires high light transmittance, the patent employs a deformable display screen that bends to create physical separation between the display surface and the camera module. This allows the use of standard display components with full functionality while the camera operates in a separate optical path below the display.
3Area of stationary object
If a pop-up front-facing camera is used, then the display area is guaranteed, but the time duration from camera pop-up to image acquiring is long
Solution Approach 1:
The deformable display screen with integrated camera positioning eliminates the need for mechanical pop-up mechanisms. The camera module remains in a ready position below the display, and the deformable region can quickly transition between states, enabling instant camera activation without the time delay associated with physical camera deployment.
4Area of stationary object
If the deformable region is kept in a bent state to maintain display area, then the display quality is improved, but the camera module cannot capture light effectively
Solution Approach 1:
The system dynamically adjusts the deformable region's state based on operational mode. During camera operation, the deformable region transitions to a flat state to align the light path from the environment through the display to the camera module. During normal display operation, it returns to a bent state to maintain full display area, thus achieving both objectives at different times.
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
The solution effectively increases the display area and improves display quality by allowing the camera module to operate without obstructing the display surface, while maintaining a compact and lightweight design.
Implementation Method 1

Implementation Method 3
the first reflective member is connected to the deformation driving part, the deformation driving part drives the first reflective member to move to a working position, and the ambient light passing through the light transmitting region is reflected by the first reflective member at the working position to the camera module
