Solution Overview
Problem
Existing display apparatuses face challenges in maintaining image display in areas where electronic components are integrated, due to limitations in design and functionality that hinder efficient use of space and light transmission.
Innovation Solution
A display apparatus with a main display area and a component area, featuring pixel groups and a transmission area, is designed. The apparatus includes a substrate with specific layers such as a buffer layer, compensation layer, and barrier layers, and utilizes a bottom metal layer to manage light and electrostatic discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components are integrated into the display area, then device functionality is improved, but image display capability deteriorates
Solution Approach 1:
The display area is segmented into a main display area for image display and a component area for electronic components. The component area is further divided into pixel groups with transparent substrates and transmission areas, allowing selective light transmission while accommodating components below the display surface.
Solution Approach 2:
The patent moves electronic components from the two-dimensional display plane to a third dimension by integrating them below the transparent substrate. This allows components to be positioned in the component area without obstructing light transmission to the main display area, resolving the conflict between component integration and image display capability.
2Illumination intensity
If transparent substrate is used in component area, then light transmittance is improved, but mechanical strength deteriorates
Solution Approach 1:
The substrate structure uses composite materials with different transparency and strength characteristics. The transparent substrate in the component area is combined with opaque barrier layers (first and second barrier layers) and bottom metal layers to create a composite structure that provides both light transmission where needed and mechanical strength through the opaque layers.
Solution Approach 2:
Different regions of the substrate have different properties: the component area has transparent substrates for light transmission, while the main display area has opaque substrates for image display. The barrier layers provide mechanical reinforcement specifically where needed, creating a non-uniform structure optimized for local functions.
3Reliability
If barrier layers are added to substrate, then reliability is improved, but device complexity increases
Solution Approach 1:
The barrier layers serve multiple functions simultaneously: they provide electrostatic discharge protection, act as adhesive layers for bonding the transparent substrate to the bottom metal layer, and function as protective barriers against environmental factors. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent combines multiple protective and functional layers into integrated barrier layers that perform multiple functions. The first and second barrier layers are integrated with the transparent substrate and bottom metal layer to form a unified protective structure, reducing the number of separate components needed for protection and assembly.

AI summary
A display apparatus includes a main display area, and a component area including pixel groups spaced apart from each other and a transmission area between the pixel groups. The display apparatus further includes a substrate including a first base layer, a compensation layer, a first barrier layer, and a second barrier layer sequentially stacked on one another, a bottom metal layer between the first barrier layer and the second barrier layer, a buffer layer on the second barrier layer, main display elements on the substrate of the main display area, and auxiliary display elements on the substrate of the component area.
