Classification: CPC G | IPC G

Claim 4:
5. The display system according to claim 3, wherein
the light source includes a plurality of light source elements,
positions that respectively overlap the temperature detection resistor elements are each provided with one or more of the light source elements,
during the period when all the scattering portions scatter light, the controller causes all the light source elements to be in an OFF state,
during the period when the scattering portion overlapping the temperature detection resistor element having the temperature equal to or higher than the first temperature scatters light, the controller causes, among the light source elements, a light source element overlapping the temperature detection resistor element having the temperature equal to or higher than the first temperature to be in an OFF state and a light source element not overlapping the temperature detection resistor element having the temperature equal to or higher than the first temperature to be in an ON state, and
during the other periods, the controller causes all the light source elements to be in an ON state.
