The Ware for May 2019 is shown below.
It’s always tough to calibrate how much of a chip to show to make it identifiable, but not too easy to guess at the same time. Let’s see how this one goes…

Seems like a TFT, OLED or E-paper row/column driver to me. Circuitry from the top row looks like a shift register + latches and the bottom row are buffers
Looks like there’s seven ‘address’ lines and two ‘power’ lines. Some kind of 128 line multi-voltage decoder/driver?
I’m going for an LCD row driver. The column drivers are more complicated (at least for a multi color LCD). The row driver is select-only, the column driver will have (non-linear) DACs.
And this chip does not have the complexity of a DAC, S/H, driver etc.
Maybe it is part (row or column driver) of some memory IC (EEPROM?). I don’t thing it’s part of display – most of them are bare-die flip chips, and here on the top are bond wires.
I think the lower edge is an actual edge, which would make this something like a 1 dimension CCD or other sensor? Perhaps like you might find in a scanner? I remember someone using a sensor like that to make a rain detector (circa 1983).
thermal printer head driver – for a label printer, maybe?
I’m thinking drop on demand driver or something similar.
A caliper perhaps?
That was my first thought, too. Those often have an ordered array of capacitive pads, but I would expect some kind of grey-code layout. I don’t see that.
I’m going to guess this is part of a die from a contact image sensor (see https://compo.canon/en/product/cis/) used in document scanners. Older scanners generally used 1-dimensional CCDs, but the bond wires on those are usually positioned on either end of a long CCD. This photo looks like a section of a very long and thin die with bond wires along one edge, which seems to match up with the contact image sensors I’ve personally seen (https://i.imgur.com/V7fHe7m.jpg).
This. Just look at the structure of ELIS1024 here http://dynamax-imaging.com/products/line-scan-product/ . It’s not that part, but they’re at least cousins!
not remotely close at all
That looks like the back of a Variable Frequency Display “VFD” Driver.

About a decade ago I helped out debugging a fingerprint sensor ASIC using an Infared thermal imaging microscope. The layout of this IC is remeninescent of that particular finger print sensor. This was before the fingerprint sensors used a matrix layout and you had to swipe the finger across the sensor array. Hence my guess is a fingerprint sensor array from Fingerprint.
