Spacer-Printed Display Assembly for Uniform Image Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-luminous electronic devices face issues with display quality due to uneven image brightness caused by non-uniform layer elements, which affect the uniformity of light-emitting elements and optical filter elements.
Innovation Solution
A manufacturing method for a display device that involves providing two substrates with light-emitting elements and optical filter elements, respectively, and using spacers to maintain a uniform distance between them, ensuring that the light-emitting elements overlap the optical filter elements to improve display quality.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional manufacturing methods are used without spacers, then the manufacturing process is simpler, but the distance between substrates is non-uniform causing uneven image brightness
Solution Approach 1:
The patent introduces spacers as intermediary elements between the first substrate and second substrate. These spacers act as mediators that maintain a uniform distance between the substrates, ensuring consistent spacing without requiring complex manufacturing processes. The spacers are formed through a printing process and serve as physical barriers that prevent direct contact between substrates, thereby achieving uniform distance and eliminating uneven image brightness.
2Illumination intensity
If layer elements are made more uniform to improve display quality, then image brightness uniformity improves, but the manufacturing process becomes more complex
Solution Approach 1:
The spacers serve as intermediary elements that ensure uniform distance between the light-emitting elements on the first substrate and the optical filter elements on the second substrate. By maintaining consistent spacing, the spacers ensure uniform light transmission and filtration, which directly improves image brightness uniformity without requiring the layer elements themselves to be manufactured with higher precision.
3Manufacturing precision
If spacers are added to uniform substrate distance, then display quality improves, but the device structure becomes more complex
Solution Approach 1:
The spacers are introduced as simple intermediary elements that maintain uniform distance between substrates. Rather than complicating the overall device structure, the spacers provide a straightforward solution by being formed through a printing process and serving as physical spacers. This adds minimal structural complexity while achieving the goal of uniform substrate distance and improved display quality.
