Abstract
A display apparatus (101), a display device, and a display method. The display apparatus (101) comprises a backlight adjustment circuit (110). The backlight adjustment circuit (110) is configured to: receive a parameter setting signal (blpro_parameter_select) used for indicating the number of frames, wherein the parameter setting signal (blpro_parameter_select) is generated in response to a dimming state switching operation, and the dimming state switching operation is used for instructing to switch from a first dimming state to a second dimming state; and in a dimming-on state, on the basis of the parameter setting signal (blpro_parameter_select), adjust a first backlight value corresponding to the first dimming state to a second backlight value corresponding to the second dimming state within a time period corresponding to the number of frames, wherein one of the first dimming state and the second dimming state is the dimming-on state, and the other is a dimming-off state. The display apparatus (101) can reduce flicker when switching between the dimming-on state and the dimming-off state, thereby improving the display effect.
