Claim 14:
15. The method according to claim 14, wherein the pad assembly integrated in the silicon-based substrate in the binding area is configured to be bound to a flexible printed circuit; and forming the array structure layer on the silicon-based substrate in the display area and forming the trace protection structure on the silicon-based substrate in the trace area comprises:
forming a first insulating layer on the silicon-based substrate, wherein the first insulating layer in the display area is formed with a first via exposing the driving transistor of the silicon-based substrate;
forming a first conductive pillar in the first via;
forming a reflective electrode and a trace protection structure on the first insulating layer by a patterning process, wherein the reflective electrode is arranged in the display area and connected with the driving transistor through the first conductive pillar, and the trace protection structure is arranged in the trace area;
forming a second insulating layer, wherein the second insulating layer in the display area is formed with a second via exposing the reflective electrode; and
forming a second conductive pillar in the second via, wherein the second conductive pillar is connected with the reflective electrode.
