That is, the number of the transporting member 31, the positioning module 32, and the probe module 33 is one, and can still be implemented.
綜上所述，透過探針模組33使該未黏貼偏光片的液晶面板半成品1通電以驅動該等液晶，透過巨觀檢測模組4A、微觀檢測模組4B、輝度檢查模組4C及光學拍照模組4D，且利用該等第一偏光片42、該等光源44及該等第二偏光片45的配合，使得在該未黏貼偏光片的液晶面板半成品1未進行下一步驟的加工，檢驗瑕疵，從而提升良率及減少不良品耗材支出，故確實能達成本發明之目的。In summary, the liquid crystal panel blank 1 of the unbonded polarizer is energized by the probe module 33 to drive the liquid crystals, and passes through the giant inspection module 4A, the micro detection module 4B, the brightness inspection module 4C, and the optical The photo module 4D is used, and the first polarizer 42, the light source 44, and the second polarizer 45 are used to make the liquid crystal panel blank 1 without the polarizer not processed in the next step. It is true that the purpose of the present invention can be achieved by inspecting defects, thereby increasing yield and reducing expenditure on consumables.
惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
