Display Substrate Pixel Layout for Under-Screen Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in achieving a high screen-to-body ratio, as front cameras occupy display regions, hindering the realization of a full-screen display.
Innovation Solution
A display substrate design with distinct pixel circuits and light-emitting devices in main and light-transmissive regions, allowing for under-screen camera integration by using different types of pixel circuits and light-emitting devices, including first and second pixel circuits and first and second light-emitting devices, with specific coupling and conductive line arrangements.

Engineering Contradiction Analysis
1Ease of operation
If a front camera is placed on the display screen, then the camera can capture images, but the screen-to-body ratio decreases and the full-screen display is compromised
Solution Approach 1:
The front camera is nested within the display screen structure, specifically integrated into the light-transmissive display region. The camera components are positioned behind the display layers, allowing the camera to function while the display area remains visually intact and uninterrupted, achieving both camera capability and full-screen display effect
Solution Approach 2:
The camera is moved from a traditional front-position arrangement to an under-screen position in the vertical dimension. By placing the camera behind the display screen and utilizing the light-transmissive properties of the display structure, the camera operates in a different spatial dimension, eliminating the need for the camera to occupy display area
2Area of stationary object
If the screen-to-body ratio is increased to achieve full-screen display, then the visual effect is improved, but the camera integration becomes more difficult
Solution Approach 1:
The display screen is divided into different regions with different optical properties: a main display region and a light-transmissive display region. The light-transmissive region has specific optical characteristics that allow light to pass through to the camera components, while the main display region provides normal display function. This local differentiation enables camera integration without compromising the overall full-screen display effect
Solution Approach 2:
A light-transmissive display region acts as an intermediary between the display function and the camera function. This intermediate structure allows light to pass through from the front to the camera while maintaining display capabilities, facilitating the integration of both functions without direct conflict

AI summary
A display substrate has a main display region and a light-transmissive display region. The display substrate includes a plurality of pixel circuits located in the main display region and including first pixel circuits and second pixel circuits, and a plurality of light-emitting devices including first light-emitting devices located in the main display region and second light-emitting devices located in the light-transmissive display region.
