Most TFT LCDs come with FPC cables that are meant to be soldered directly to the PCB. They do this since it’s cheaper than using an external connector, but it might seem a bit tough to solder them by hand. All you really need is some thin enough solder wire (0.4mm is used here), and a bit of magnification (this video was shot using a microscope at 5x magnification … nothing terribly exotic and inexpensive magnifying glasses can provide similar magnification). Be sure to use a no clean solder paste, though, or no clean flux if you want to remove any bridges since you won’t be able to wash the PCBs in water since you’ll ruin the LCD. (For reference sake, the LCD was aligned to the pads on the PCB and secured using Kapton tape … you can see the yellow tape just above the pads on the FPC cable.)
