Analysis of defects in overseas manufactured displays.
Numerous achievements in defect analysis! Detailed analysis is possible, from confirming phenomena to hypothesizing the mechanisms of defect occurrence.
Our company conducts "defect analysis of overseas manufactured displays." We can perform detailed analysis from confirming the phenomenon, hypothesizing the defect occurrence mechanism, to narrowing down the production processes that caused the issue. We carry out lighting observations, panel disassembly, and optical microscope observations tailored to the defect symptoms. If it is necessary to narrow down the defective areas and conduct detailed analysis, we will propose appropriate methods. 【Examples of detailed analysis (partial)】 ■ Cross-sectional observation of wiring ■ Foreign object analysis ■ Liquid crystal component analysis ■ Electrical characteristic measurement *Additional costs will be incurred. *For more details, please refer to the PDF document or feel free to contact us.

Observation of Conductive Particle Shape in COG Implementation
We will introduce the observation of the shape of conductive particles in COG implementation. ICs and liquid crystal panels are implemented using the COG method with ACF (anisotropic conductive film). A resin ball is used as the core, and a metal layer (such as nickel or gold) for conductivity is deposited on its surface. During connection, the particles deform appropriately to electrically connect the IC and the panel. To confirm the degree of particle deformation and connection status, cross-sectional observations were conducted, revealing that the particle deformation was at a "medium" level, indicating an appropriate degree of deformation. By examining the deformation of conductive particles from both the planar and cross-sectional directions, we can explore the correlation with display defects. Please feel free to contact us for any inquiries regarding panel-related defects.

Analysis of defects in overseas manufactured displays.
Our company conducts "failure analysis of overseas displays." We can perform detailed analyses, from confirming the phenomenon to hypothesizing the failure mechanism and narrowing down the production processes that caused the issue. We carry out lighting observations, panel disassembly, and optical microscope observations tailored to the failure symptoms. If it is necessary to narrow down the defective areas and conduct a detailed analysis, we will propose appropriate methods.
