Detailed description of the invention
The display that there is foreign body for liquid crystal indicator module present in prior art and produce is bad
Problem, embodiments provides a kind of method for maintaining showing module and device.First, the present invention is real
Execute example provide display module method for maintaining flow process as it is shown in figure 1, the embodiment of the present invention provide above-mentioned
The method for maintaining of display module, performs step as follows successively:
