• Such (scale LCD) displays are multiplexed. In other words, when you look at one 'pin' of the LCD, you see a on-off-on-off-... signal. Multiplexing is a technique to reduce the number of connections. I would be surprised when these cheapo things - chip under the black blob - would provide connectivity to an information/externalize a signal that would tell you something about the weight on the scale. Most of these boards have test pads. I would start of with a simple multi-meter and see if one of the golden, shiny pads provide you with a signal that you can use.
