Electronic – What type of display is this


I found this display in this cheap chinese handheld tetris. It doesn't have any connectors on itself and is just sitting on small PCB with some kind of gum between them. What kind of display is it and how can I power it with eg. arduino?

That's a simple custom LCD. The "gum" you are talking about is called a Zebra Strip and it transfers the signals from the PCB to the display. Some pressure is required for a good connection, so some sort of bracket is normally used to hold the LCD in place.

The LCD does not have an integrated display driver, it will be located on the PCB. If you really wanted to make use of this LCD, your best bet would be to hack the game itself and somehow tap into the LCD driver. To be honest, it's more trouble than it's worth.
