Camera-Overlapped Display Pixel Layout With Shared Transistors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with embedded cameras experience image discontinuity and reduced light transmittance in areas where the camera hole is formed, leading to incomplete image display and reduced visibility.
Innovation Solution
A display device design with a substrate featuring separate display areas, one area for the camera and another for image display, where the camera area includes transmissive regions and shared transistors for subpixels, reducing the need for circuit elements and enhancing light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera hole is provided to arrange the camera, then the camera can be embedded in the display device, but the image display becomes disconnected and light transmittance is reduced in the camera hole area
Solution Approach 1:
The patent converts the harmful effect of the camera hole (which blocks light and disrupts image display) into a beneficial feature by making the hole transmissive. The camera hole area is designed to allow light passage and image display while still accommodating the camera, thus transforming the obstruction into a transparent window that serves dual purposes: camera access and light transmission for both display and camera functions.
2Extent of automation
If circuit elements are provided in the camera hole area, then the camera can be controlled, but light transmittance is further reduced
Solution Approach 1:
The patent separates circuit elements from the camera hole area by placing them in different spatial dimensions or regions. The control circuits are positioned in surrounding areas or integrated in a way that does not occupy the central light transmission path of the camera hole, allowing optical clarity while maintaining electrical control functionality through strategic spatial arrangement.
3Illumination intensity
If the camera hole area is made transmissive for light, then light transmittance is improved, but image display quality may be compromised
Solution Approach 1:
The patent applies different properties to different regions: the camera hole area is made transmissive with optimized optical characteristics for light passage, while surrounding areas maintain standard display properties. This localized differentiation allows the camera hole region to function as a high-transmittance window without compromising the overall image display quality in other regions, achieving spatially optimized performance.
Data Source
AI summary
A display device is disclosed, which may display an image even in an area overlapped with a camera and have high light transmittance. The display device comprises a substrate provided with a display area including a first display area and a second display area, a first transistor provided in the first display area over the substrate, a second transistor provided in the second display area over the substrate, a first subpixel supplied with a power source from the first transistor, and a second subpixel supplied with a power source from the second transistor. At least two or more second subpixels share one second transistor.
