Abstract:
1. A tunable current driver for a flat-panel display, which comprising: a semiconductor memory device, comprising: a first gate electrode; a first trapping layer disposed under the first gate electrode; a first gate oxide layer disposed under the first trapping layer; a first polysilicon layer disposed under the first gate oxide layer and on a glass substrate; a first source/drain pair formed in the first polysilicon layer at opposing sides of the first gate electrode, wherein one of the first source/drain pair is electrically coupled with a lighting device; a selective transistor comprising a second gate electrode and a second source/drain pair, wherein one of the second source/drain pair is electrically coupled with the first gate electrode, the other of the second source/drain pair is electrically coupled with a data line, and the second gate electrode is electrically coupled with a select line; and at least one buffer layer disposed between the first polysilicon layer and the glass substrate.
