发明名称 Liquid crystal display apparatus and method for checking the joining accuracy thereof
摘要 The present invention provides an LCD apparatus and a method for checking the joining accuracy thereof. The LCD apparatus comprises an LCD panel, a printed circuit board and a package unit coupled to the LCD panel. On the printed circuit board, there is a plurality of first pins, a first check pad and a second pad, wherein at least one first pin is electrically connected to the first check pad and at least another first pin is electrically connected to the second check pad. There is a plurality of second pins on the package unit, wherein the second pins join the first pins on the printed circuit board correspondingly to connect the first pins electrically. To check the joining accuracy of the LCD apparatus, electric resistance is obtained by measuring the resistance between the first and second check pad with an ohmmeter. When the measured resistance is below a reference value, the assembly quality of the LCD is not qualified.
