Inkjet Printer Test Film Segmentation for Jetting Error Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display inkjet printer apparatuses, jetting errors can occur due to the direction of nozzles, and correcting these errors using a single test pattern on a test film increases the replacement cycle and production cost of the test film.
Innovation Solution
A method of substrate processing that forms multiple test patterns on a single test film, allowing for the calibration of jet values from different areas of the test film to optimize substrate jetting, thereby reducing the replacement cycle and production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single test pattern is formed on a single test film to correct jetting errors, then the jetting error correction can be performed, but the replacement cycle of the test film increases and the production cost increases
Solution Approach 1:
The test film is divided into multiple test areas (first test area, second test area, third test area, etc.) arranged in sequence along the substrate processing direction. Each test area contains a test pattern used for correcting jetting errors at different positions, allowing multiple correction cycles per single test film without replacement.
2Device complexity
If a single test pattern is formed on a single test film, then the test film structure is simple, but the production cost of the test film increases
Solution Approach 1:
The test film is segmented into multiple functional test areas along the processing direction, with each area containing test patterns for specific jetting error corrections. This segmentation allows one test film to serve multiple correction cycles, reducing the frequency of film replacement and production costs while maintaining relatively simple individual test pattern structures.
Solution Approach 2:
The test film is designed with multi-functionality by incorporating multiple test areas that can be sequentially used for different jetting error corrections. A single test film performs multiple correction functions across different test areas, reducing the need for frequent film replacement and lowering production costs.
3Productivity
If multiple test patterns are formed on a single test film, then the efficiency of the test film is maximized, but the complexity of processing increases
Solution Approach 1:
The test film is divided into multiple test areas arranged in sequence along the substrate processing direction. Each test area contains test patterns for specific jetting error corrections, allowing the system to process multiple corrections sequentially without increasing overall processing complexity, as each area is handled independently in the sequence.
Solution Approach 2:
The test patterns are pre-formed on the test film in advance during film preparation. The jet values are obtained from these pre-formed patterns before actual substrate processing begins, allowing the complexity of multiple pattern formations to be performed beforehand when the test film is created, rather than during each substrate processing cycle.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method maximizes the efficiency of the test film by reducing the replacement cycle and minimizing errors in jet values, thereby lowering production costs and improving substrate processing accuracy.

AI summary
In a method of processing a substrate, a test film having a first area and a second area adjacent to the first area is provided. A first jet value is obtained from a first test pattern formed by jetting a chemical solution through a plurality of nozzles onto the first area of the test film. The chemical solution is jetted onto a first substrate based on the first jet value. A second jet value is obtained from a second test pattern formed by jetting the chemical solution through the plurality of nozzles onto the second area of the test film. The chemical solution is jetted onto a second substrate based on the second jet value.
