摘要 |
A resistive element is connected in series to a cathode terminal of an LED light source at a last stage (or an anode terminal of an LED light source at a first stage) of an LED chain, and a resistance value of the resistive element is configured to be variable in resistance value in accordance with a variation of voltage drops of the LEDs connected in series so that a resistance value of a resistive element connected to an LED chain having a large voltage drop has a smaller resistance value then a resistance value of a resistive element connected to an LED chain having a small voltage drop. With this configuration, the power, which has been wasted otherwise as heat in the backlight driver IC, may be dispersed to the resistive elements. |
