Film Edge Profiling for Overlapping Shape Thickness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods struggle to control film thickness at the boundaries between overlapping shapes in images, particularly when printing images with multiple shapes, which is necessary for producing products with minimized bezels and internal sensors like cameras.
Innovation Solution
An apparatus and method that independently control the film formation on the edges of each shape by setting edge processing profiles and using a control unit to manage the nozzle's discharge amount and movement based on these profiles, allowing precise film thickness control in overlapping image regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional film formation methods are used, then simple rectangular images can be printed, but film thickness cannot be controlled at boundaries between overlapping shapes
Solution Approach 1:
The patent segments the image into multiple independent shape regions, each with its own edge detection and film thickness control parameters. The control unit processes each shape separately, identifying edge portions of individual shapes even when they overlap, allowing independent film formation control for each shape's boundary
Solution Approach 2:
The patent applies local quality by setting different film thickness targets and edge processing profiles for different regions of the substrate. Each shape's edge portion receives customized film formation parameters based on its specific geometric characteristics and overlap relationships with adjacent shapes
2Area of stationary object
If full screen displays with minimized bezels are produced, then display area is increased, but control of film thickness at shape boundaries becomes more difficult
Solution Approach 1:
The patent performs preliminary actions by pre-defining edge processing profiles and film thickness targets for each shape before the actual film formation process. The control unit prepares the complete processing scheme for all shapes including their edge portions, ensuring that even in complex overlapping configurations, the film thickness can be precisely controlled at all boundaries

AI summary
The present disclosure provides a method and apparatus for forming a film, capable of for forming a film on an image in which a plurality of shapes overlap, wherein the method for forming a film includes setting a first shape within a target region; setting a second shape, at least partially overlapping the first shape; setting an edge processing profile applied to an edge portion of the first shape and an edge portion of the second shape; and forming a film on the edge portion of the first shape and the edge portion of the second shape, based on the edge processing profile.
