FIELD: physics.
SUBSTANCE: disclosed display device 10 includes a display panel 10, a fluorescent lamp 17, a brightness controller 40 and a thermosensitive element TS. The display panel 10 displays the gray scale. The fluorescent lamp 17 emits light towards the display panel 10. The brightness controller 40 controls display brightness by adjusting the gray scale of the display panel 10 and light emission of the fluorescent lamp 17. The thermosensitive element TS measures temperature of the display device 10. The brightness controller 40 selects the method of controlling brightness from adjusting the gray scale of the display panel, adjusting emission of the fluorescent lamp 17 and a combination of both based on the temperature of the display device 10, measured by the thermosensitive element TS.
EFFECT: improved device.
