If you already have an LED display that shows battery level and pedal assist level, an LCD display is just an ornament. You won't get much new information. The KT LCD-3 give speed/distance/time, outside temperature, battery indicator, pedal assist level, battery voltage, and current power being used in watts. After a week or two, you only care about PAS level, and speed/distance, but an inexpensive bike computer where you put in the wheel circumference is more accurate.

If you like gadgets that are inexpensive, you might consider a wattmeter. These will also tell you the battery voltage, and current. It calculates amp-hours and watt-hours, except I have found only Amp-hours is accurate. It is wired in-between the battery and controller, and cannot be mounted on the handlebars because the wiring is too long. I use them to measure the amp-hours my bikes use, and then I can evaluate the quality of my various batteries. Probably $15 USD on Aliexpress.

In your other thread you wanted to upgrade the motor. What is the top speed of your ebike now? If a new controller/display cannot help that, and you will have spent $100 USD for no imporvement.
