In the production of the flat panel, the size of the discontinuous dimension and the pair of lower glass usually have a tolerance of about 1 mm. Because the upper and lower slopes of the flat panel have no alignment marks, the precision alignment cannot be performed. To make a pair on the glass bowl and downhill, and use the precision alignment equipment to carry out the pairing, then the multi-production pair is only marked. Traditionally, the flat panel is installed in the back frame of the backlight module. , two pivots: the cost. The upper and lower glass are the same size. However, because the upper and lower glass pairs are substantially larger in terms of design considerations, the size of the back frame still needs to match the tolerance of the pair 2 and the size of the lower glass, resulting in the close installation of the flat lamp panel. The back frame 2 is slightly larger than the middle shake. At present, the tolerance accuracy required for the combination of the backlight modules is less than that of Q e. The tolerance between the glass and the lower glass pair on the back frame is too large, so that the precision alignment _. Because S = due to the ineffective circulation of the flat panel, there will be dark bands or poor uniformity around the group in the open area of the back group. And a large tolerance is also available for production ^ = After the light board and the back pool are installed (4), and the correcting plane light board hits the displacement of the back, which will not only produce abnormal sound, but also easily damage the flat light board.
