I'm designing a circuit driving 4K pixels with chrt35 process. So the size of the array is about 7mm * 7mm . And I use a common voltage to bias every amplifiers in pixels.
But I have no idea about the variation in threshold voltage(Vth) across the die. Is the mismatch of these devices serious?

You should find this information in the PDK documentation of your process. If not, ask Chrt.
