Can the digital oscilloscope display G321EV be replaced with a different model?

Hallo every one

This is one of my oscilloscopes. I have been using it for many years.
Recently I noticed a circular shadow in the center of the screen,It looks like the glue that bonds the LCD has aged.
I was wondering if there is a replacement for this model of LCD screen?Because the same model is very expensive

The LCD module model is G321EV. Is there any other model of LCD module that can be a perfect replacement?
Because if I buy the G321EV, after a period of use, the aging will appear again. I hope to completely solve the screen aging.

You need to separate the screen from the PCB and see if there's any numbers printed on it.

Electrically, it should work with the same screen size, resolution, and controller.
But mechanically, I don't think it can be installed. It is better to purchase the same LCD panel or replace the polarizer.

As I thought, I initially mistakenly thought it was caused by the aging of the polarizer, but please see the following picture

The entire screen is made of a horizontal liquid crystal and a vertical liquid crystal bonded together.The horizontal direction is welded by zebra strips, and the vertical direction is conductive rubber.

I guess it's because the glue that bonds them together has aged.
If I buy the same model, I estimate that the same problem will occur again after a period of time, so I hope to completely solve this problem.

It looks like the LCD module model is G321EV。
There is no point in buying the same model because the fault will reoccur over time, so I am looking for a perfect replacement model.
