Character LCD Modules dot defect analysis and research

LCD panel in the manufacturing process, which can be roughly divided into three stages: array (array), into the box (cel1), the module (module). Although most of LCD panel manufacturing process 

Is done in the high cleanliness of the clean room, but still inevitably on the custom LCD display will appear some defects. There are many reasons that cause these defects, in all of its manufacturing 

A link has defects. In a box of phase formation of the pinhole defect and black dot defect is two more common point defects. 

When perfusion liquid crystal box if vacuum bubble, namely the pinhole defects; If some particles in perfusion liquid crystal before the supers group (particle cluster), either 

When pouring the serial LCDs crystal box were mixed with some particles, which cause the black point defects. 

Point defects at the core of the will of the surrounding have anchoring effect of the liquid crystal molecules, so will inevitably shadow Ⅱ to the liquid crystal molecules are arranged in certain ranges. Based on two typical point defects 

Core research, found that the different defects affect the ability of the liquid crystal molecules are arranged around there are significantly different, and through the extrapolation length theory and elastic long-range correlation theory into the phenomenon of the experiment 

Line of argument.
