摘要
A new drive method designed for the adaptive local dimming lighting of a multistructured 32-in diagonal-sized mercury-free flat fluorescent lamp (MFFL) which consists of a matrix array of 10 x 16 60-mm diagonal-sized unit cells is proposed. The adoption of the dual auxiliary electrode and the bipolar-pulse drive scheme resulted in a wide stable operating voltage margin at low driving voltages. The cell turn-on or turn-off selectivity can be obtained through the change of the connection state of the dual electrode. Using the proposed MFFL with the dual auxiliary electrode as a data electrode and the subfield method, a new drive scheme for a 2-b adaptive local dimming control of 10 x 16 lamp array with one inverter system is proposed and demonstrated.
