Dell 88YTC LCD back cover assembly is a replacement rear cover for the display of compatible Dell laptops. It provides the display’s rear housing and includes integrated WLAN antenna cables.
The 14-inch assembly is listed for Latitude 5420 and Latitude 5430. Dell also lists it for Latitude 5431 and Precision 3470. The included two WLAN antenna cables are intended for systems configured with WLAN only.
The cover supports infrared or HD cameras, allowing it to be used with those camera configurations. It is a display cover assembly rather than a complete screen, so the confirmed purpose is to provide the rear cover and WLAN antenna arrangement for the compatible laptop display.
