Abstract:
The present invention discloses a thin film transistor (TFT) drive backplane and a Micro- light emitting diode (LED) display that by employing a structure of an oxide thin film transistor drive backplane with a high mobility can achieve fulfillment of the need for large size Micro-LED displays. Disposing the rear metal layer under the base substrate with the rear metal layer including a metal wire layer configured to connect with a drive chip and a metal light shielding layer configured to block ambient light reduces a spliced bezel of the display panel in application of large size Micro-LED displays, reduces depositing and patterning steps of the metal light shielding layer during manufacturing the thin film transistors and further reduces process steps of manufacturing a TFT drive backplane.
