Can I use a 1k potentiometer on my LCD?

I bought an LCD yesterday and I was trying to use it. But, I don't have a 10k potentiometer for contrast. I just have a 1k. Can I use it without risks?

Just connect two terminals to VO and GND. i.e. slider to VO and one end terminal to GND. It is not necessary to connect the other end to 5V.

The best contrast will be about half-way i.e. about 500R.

The difference between using a 1k vs a 10k is that 1k pot will consume (waste) a bit more power
since the pots are typically connected across power and ground to create a simple voltage divider.
Because of this, it will always consume (waste) some amount of power as there is a current path between VCC and ground through the pot.
That amount of power can be calculated using ohms law V=IR.
At 5v,
10k pot: 5 = 10000I so I = 5/10000 or 0.0005 AMPS or 0.5ma
1k pot: 5 = 1000I so I = 5/1000 or 0.005 AMPS or 5ma

So a 1k pot will consume (waste) an extra 4.5ma vs a 10k pot.
If the extra power is not an issue, then it is of no real concern.

And as David mentioned, you can omit the vcc connection to the pot since the LCD module has some on board resistors that can be used as the other side of the voltage divider.
This can totally eliminate the waste current mentioned above.
