Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective film is attached on a combination of a glass lower substrate and a thin-film encapsulation member, then the thin-film encapsulation member and organic light-emitting device are protected from external impurities, but it becomes difficult to perform scribing operation
Solution Approach 1:
The protective film is divided into a target area (remaining on display cells) and a dummy area (removed before scribing). By segmenting the protective film's functionality in space, the dummy area can be removed to enable scribing operations, while the target area remains to provide protection during subsequent processes.
Solution Approach 2:
The dummy area of the protective film is removed in advance before the scribing operation. This preliminary action eliminates the obstacle that would prevent proper scribing, allowing cutting lines to be formed accurately without the protective film interfering with the process.
2Manufacturing precision
If the protective film is peeled off after scribing, then the scribing operation can be performed accurately, but the process time and complexity increase
Solution Approach 1:
Instead of peeling the protective film after scribing, the dummy area is removed in advance before scribing. This reverses the sequence of operations, eliminating the need for post-scribing peeling steps and reducing overall process time while maintaining scribing accuracy.
Solution Approach 2:
The protective film is segmented into target and dummy areas with different fates. The dummy area is removed beforehand to enable accurate scribing, while the target area remains for later protection, eliminating redundant peeling steps and streamlining the manufacturing process.
3Productivity
If additional cutting lines are formed near the cutting line, then the peeling process becomes more controlled and efficient, but the manufacturing steps increase
Solution Approach 1:
Additional cutting lines are introduced to further segment the dummy area of the protective film. These auxiliary cutting lines create smaller sections that can be more easily and efficiently removed, improving peeling control and efficiency despite adding one more manufacturing step.

AI summary
A method of peeling a mother protective film from a mother display panel includes: laminating the mother display panel and the mother protective film, the mother display panel including a plurality of display cells each including a display area and a peripheral area around the plurality of display cells; forming a target area and a dummy area in the mother protective film by forming a cutting line in a closed loop shape enclosing the target area corresponding to each of the display cells and a first additional cutting line in a first direction near the cutting line; physically peeling off the dummy area from the mother display panel, including: primarily peeling off a portion of the mother protective film adjacent to the first additional cutting line; and secondarily peeling off rest of the mother protective film from the mother display panel along the cutting line.
