LIGHT SOURCE DRIVING CIRCUIT, LIGHT SOURCE COMPONENT PROVIDED WITH THE LIGHT SOURCE DRIVING CIRCUIT, AND DISPLAY APPARATUS
Provided are a light-source drive circuit substrate and a light source component which can drive a light source with sufficiently high light source characteristics even when environmental temperature greatly changes, and a display apparatus which includes the light source component. A light-source drive circuit (X) according to the present embodiment includes a controller (C) configured to drive a first light source (L1) and a second light source (L2) having at least one light source characteristics higher than those of the first light source (L1) when the environmental temperature is equal to or below a reference temperature. The controller (C) includes a selector (10) which selects a first driver (D1) for driving the first light source (L1) when the environmental temperature goes above the reference temperature, and selects a second driver (D2) for driving the second light source (L2) when the environmental temperature becomes equal to or below the reference temperature.
