Description
Technical field
The utility model belongs to liquid crystal display detection device technical field, is to be related to a kind of liquid crystal more specifically
Show that device panel detection device, the utility model further relate to a kind of LCD panel detector detection method.
Background technique
Thin Film Transistor-LCD (Thin Film Transistor Liquid Crystal Display, referred to as
TFT-LCD) graduallyd mature from an emerging industry, therefore small in size, low-power consumption, it is light-weight, the advantages such as beauty and obtain
Extensive concern and research.With portable computer, office application, the extensive use of big screen display screen, people are for display
Quality has higher requirement.Therefore display pannel manufacturer is for showing broken bright spot bad (Zara Particle, abbreviation
P/T) there are more strict requirements.Current liquid crystal display panel is mainly wide viewing angle direction, traditional twisted nematic
(Twisted Nematic, TN type) panel is no longer satisfied the requirement of client.In order to meet the requirement of wide viewing angle, side
Edge field-effect (Fringe Field Switching, abbreviation FFS) wide viewing angle type liquid crystal display panel is developed.But
The reason of it is bad that FFS mode panel is easier to occur broken bright spot, generates Zara P/T has very much, such as liquid crystal structure design, system
Make technique etc..It is generally acknowledged that Zara P/T is mainly since friction process causes.In the process that liquid crystal surface is thinned
Polish, and become the link of the high risk of Zara P/T generation.Since the Zara P/T bad problem is in common fluorescent lamp
Inspection under be can not detected, therefore how to improve and control polishing after liquid crystal display panel Zara P/T it is bad, also become
Critically important requirement one of of the factory to panel polishing quality control is thinned；It is usually to pass through when detection Zara P/T is bad at present
The automatic lighting machine of mould group is detected, if to generate Zara P/T bad for the TFT-LCD panel that has polished, then caused by broken bright spot
It is bad will be it is bulk bad, lose it is huge.Therefore TFT-LCD panel how is controlled during the polishing process, it will be able in time
It was found that it is bad, inhibit bad to remain one of current long-standing bottleneck of thinning manufacturer.
Utility model content
The technical problem to be solved by the utility model is in view of the deficiencies of the prior art, it is simple to provide a kind of structure, energy
Enough convenient and efficient broken bright spots of display to panel of LCD (panel, thinning panel) detect, before realizing detection process
