Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in incorporating optical electronic devices, such as cameras and sensors, which require increased bezel size or notches, leading to reduced image quality and impaired performance due to the placement of these devices on the front surface, affecting the design and functionality.
Innovation Solution
A display panel structure with a light transmission area that allows optical electronic devices to receive light without being exposed on the front surface, featuring a substrate with optical areas for image display and normal areas for light transmission, including light emitting elements, color filters, and light shields to enhance transmittance and prevent malfunctioning due to external light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an optical electronic device is located in a front portion of the display device to allow it to receive incident light, then the light receiving capability is improved, but the bezel area increases or a notch/hole must be formed in the display area
Solution Approach 1:
The patent moves the optical electronic device from the front surface (2D plane) to the rear side of the display device, utilizing the third dimension (depth) to resolve the contradiction. This allows the device to receive light transmitted through the display panel without occupying front surface area, thereby maintaining full display area while ensuring adequate light reception capability.
2Illumination intensity
If an optical electronic device is located in a front portion of the display device, then the light receiving capability is improved, but the image quality decreases and performance is impaired
Solution Approach 1:
The patent extracts the optical electronic device from the front portion of the display device and relocates it to the rear side. This separation removes the device from the image display area, eliminating interference with image quality while maintaining its light receiving function through the transmitted light path.
3Ease of manufacture
If the bezel area is increased to install an optical electronic device, then the device can be properly installed, but the display area is reduced
Solution Approach 1:
The patent utilizes the rear side of the display device (third dimension) to install the optical electronic device, thereby eliminating the need to increase bezel area or reduce display area. This dimensional relocation allows full utilization of the front surface for display purposes while providing adequate space for device installation on the rear side.
