Camera Under Display Light Elements Masking Pixel Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile electronic devices, the integration of a front-facing camera behind a display surface is hindered by bezels or notches, reducing the display area and causing display artifacts due to the reduced density of camera display pixels, which affects the aesthetic appearance and longevity of the display.
Innovation Solution
A system and method where light elements, such as LEDs, are positioned proximate to the camera display pixels to emit an auxiliary light output, matching the display information like color and brightness, thereby filling in the gaps created by reduced camera display pixels, enhancing the aesthetic appearance and maintaining it throughout the display's lifetime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If camera display pixels are reduced to minimize display artifacts, then display artifact appearance is improved, but display lifetime is decreased
Solution Approach 1:
Light elements are introduced as intermediary components positioned between the camera sensor and the display pixels. These light elements emit auxiliary light through the openings defined by camera display pixels, compensating for the reduced pixel density and masking the appearance of display artifacts while the camera display pixels maintain their reduced density configuration.
Solution Approach 2:
The solution applies local quality by positioning light elements specifically in the camera-under-display (CUD) region where camera display pixels are reduced, rather than uniformly across the entire display. The light elements are strategically placed to emit light through openings where camera display pixels are less dense, providing localized compensation only where needed to mask artifacts without affecting other display regions.
2Object-generated harmful factors
If camera display pixels are reduced to minimize display artifacts, then display artifact appearance is improved, but wear pattern uniformity is decreased
Solution Approach 1:
Light elements serve as intermediary components that emit auxiliary light through the CUD region openings, creating a uniform visual appearance across the display. This compensates for the non-uniform wear patterns caused by reduced camera display pixel density, as the auxiliary light masks the visual differences in pixel wear between the CUD region and other display areas.
Solution Approach 2:
The light elements can modify the color and brightness characteristics of light passing through the CUD region. By adjusting the color temperature and intensity of auxiliary light, the system can match the appearance of surrounding display pixels, creating visual uniformity that compensates for underlying pixel density differences and wear pattern variations.
3Area of stationary object
If bezels or notches are eliminated to increase display area, then display area is increased, but camera integration complexity is increased
Solution Approach 1:
The patent implements nesting by placing the camera sensor underneath the display stack, with the display pixels and light elements positioned above the camera sensor. The camera display pixels define openings that allow light from the scene to reach the camera sensor while still maintaining a display structure above. This nested arrangement eliminates the need for separate bezels or notches, as the camera is integrated within the display layers themselves.
Solution Approach 2:
The solution moves the camera from a traditional side-by-side arrangement (sharing the same surface plane as the display) to a vertical stacking arrangement in another dimension. By placing the camera sensor underneath the display stack along the vertical axis, the system eliminates horizontal space requirements for bezels or notches, thereby maximizing display area while integrating camera functionality through the display layers.
