Samsung uses AMOLED display not a LCD display. Those are already more expensive than other technologies. The glass/digitizer (touchscreen) by itself is inexpensive because it is difficult to do a glass only repair. You will need special tools to separate the old glass form the display, then you will need special tools to re-adhere the new glass to the display. You can’t do a good job without those tools. If you have never done this type of repair you will most likely destroy the glass as well as the display. It is really not easy unless you have done this a couple of times. Spend the extra money and replace the complete display assembly.
