Note 5
Note 1: DP-1 are AUO recommended Design Points.
*1 All of characteristics listed are measured under the condition using the AUO Test inverter.
*2 In case of using an inverter other than listed, it is recommended to check the inverter carefully. Sometimes,
interfering noise stripes appear on the screen, and substandard luminance or flicker at low power may happen.
*3 In designing an inverter, it is suggested to check safety circuit ver carefully. Impedance of CCFL, for instance,
becomes more than 1 [M ohm] when CCFL is damaged.
