The Dell Inspiron 15R N5010 laptop is a bit older, so finding specific parts might be a bit challenging. The display ribbon, also known as the LVDS cable, connects the laptop's motherboard to the display panel, allowing data to be transmitted and displayed on the screen. If you need a replacement display ribbon for your Dell 15R N5010, your best bet would be to search for it on online marketplaces like eBay or Amazon. You can also try contacting Dell support or authorized Dell service centers to inquire about availability. Additionally, you might find third-party electronics repair shops that specialize in laptop repairs and might have the necessary parts or be able to order them for you.
