Solution Overview
Problem
Current display technologies face challenges in achieving a true full-screen display due to the separation of camera and display areas, leading to visual discontinuation and high costs associated with MicroLED pixel transfer in mass production.
Innovation Solution
A display device with a backlight module featuring a transmissive area equipped with MicroLED light-emitting units on a transparent substrate, allowing for maximum transmittance and enabling a full-screen display when the camera module is not in use, while minimizing the number of MicroLEDs required and avoiding high costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera module is integrated into the display area, then the camera functionality is improved, but the display area is reduced causing visual discontinuation
Solution Approach 1:
The camera module is positioned in the backlight area rather than the display area, utilizing the space dimension behind the display panel. This allows the camera to function without occupying the visible display area, eliminating visual discontinuation while maintaining full-screen display capability.
Solution Approach 2:
The camera module is nested within the backlight module structure, specifically utilizing the backlight area space. This nested arrangement allows both the camera and display to coexist without interfering with each other's functionality or visual appearance.
2Illumination intensity
If MicroLED pixels are transferred for full-screen coverage, then the display quality is improved, but the manufacturing cost and complexity increase significantly
Solution Approach 1:
The display area is segmented into two functional zones: the display area using traditional LCD technology and the backlight area using MicroLED technology. This segmentation allows MicroLED to be used only where needed (backlight support) rather than across the entire screen, significantly reducing manufacturing complexity and cost.
Solution Approach 2:
Different technologies are applied to different areas based on local requirements: LCD for the display area where cost-effectiveness is prioritized, and MicroLED for the backlight area where high brightness and stability are needed. This local quality approach optimizes both performance and manufacturing feasibility.
3Reliability
If the entire display area uses MicroLED technology, then the stability and brightness are improved, but the manufacturing yield decreases and cost increases
Solution Approach 1:
The display system is divided into two technological segments: LCD for the display area and MicroLED for the backlight area. This segmentation limits MicroLED application to a smaller, manageable area, improving manufacturing yield while still achieving the desired stability and brightness benefits in the backlight region.
