0.87" oled

This product hasn't been fully tested yet.
When I tested it, the display did turn on, but the brightness was low and there were glitches in some areas of the screen.
It’s likely due to a soldering error on my part, but I can't rule out a possible design flaw.

Here is the datasheet for my display: https://www.icbanq.com/P008340439?srsltid=AfmBOoq5eM-wmIhzyNuzChaidlS66cmxkPn04IoP3YQqENMwCRiZblcn
