Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in implementing a full-screen display on mobile terminals is the limited screen size due to the presence of cameras and sensors, which requires innovative solutions to integrate imaging regions without compromising visibility or performance.
Innovation Solution
A display device with a first display region and a second imaging region, where the imaging region is not visible from the outside, utilizing a light-transmitting module that controls light passage through specific regions to accommodate optical sensors and improve camera performance by ensuring sufficient light is incident when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera and sensors are disposed in or under the imaging region, then the imaging function is enabled, but the imaging region becomes visible from the outside and full-screen display is compromised
Solution Approach 1:
The patent applies the dynamics principle by making the light-transmitting regions switchable between transparent and opaque states. When the optical sensor is active, the light-transmitting regions become transparent to allow light passage for imaging. When the optical sensor is inactive, the light-transmitting regions become opaque to hide the imaging region and maintain full-screen display appearance. This dynamic state change resolves the contradiction between enabling imaging function and maintaining full-screen display.
Solution Approach 2:
The patent applies the color changes principle by controlling the optical properties of the light-transmitting regions. The regions change their light transmission characteristics (from transparent to opaque) based on the operational state of the optical sensor. This optical property change allows the imaging region to be hidden when not in use, maintaining the full-screen display appearance while enabling imaging functionality when needed.
2Reliability
If light-transmitting regions are provided in the imaging region, then camera performance is improved by allowing light passage, but the imaging region is visible from the outside
Solution Approach 1:
The patent makes the light-transmitting regions dynamically controllable, switching between transparent and opaque states based on sensor operation. When the optical sensor is active, the regions become transparent to maximize light passage and improve camera performance. When inactive, they become opaque to conceal the imaging region. This dynamic control resolves the contradiction between improving camera performance and hiding the imaging region.
Solution Approach 2:
The patent introduces an intermediary control mechanism (the opening/closing module) that mediates between the light-transmitting regions and the external environment. This intermediary controls the optical state of the light-transmitting regions, allowing them to be transparent when needed for camera operation and opaque when hiding is required, thus resolving the contradiction between camera performance and imaging region visibility.
3Shape
If the imaging region is hidden, then full-screen display is achieved, but light passage for camera operation is blocked
Solution Approach 1:
The patent applies dynamics by making the light-transmitting regions switchable between opaque and transparent states. When the optical sensor is inactive, the regions remain opaque to maintain full-screen display appearance. When the optical sensor becomes active, the regions switch to transparent state to allow sufficient light passage for camera operation. This dynamic switching resolves the contradiction between maintaining full-screen display and enabling light passage.
Solution Approach 2:
The patent implements periodic action by alternating the optical state of the light-transmitting regions based on the operational cycles of the optical sensor. The regions switch between opaque (display mode) and transparent (imaging mode) states in sync with sensor operation cycles. This periodic state change allows the system to maintain full-screen display appearance during non-imaging periods while enabling light passage during imaging periods.
