Hi @anuradha45076
The touch screen is integrated with the LCD panel. If the touch screen is cracked then the entire display panel needs to be replaced
Here's the [http://h10032.www1.hp.com/ctg/Manual/c06040336.pdf|maintenance and service guide] taken from this support [https://support.hp.com/au-en/product/setup-user-guides/hp-pavilion-11-ad100-x360-convertible-pc/model/22780934|webpage] for the laptop.
Go to p.53 to view the procedure to remove/replace the display assembly.
Search online for ''925388-001'' (see p.55 to view the display's spare part number) to find suppliers of the display assembly, that suit you best.
