The present invention provides an image display method and a display system, belongs to the field of display technology, and can solve the problem of large power consumption in an existing image display method when displaying images. The image display method of the present invention comprises: determining a utilization ratio of a CPU according to a pre-acquired working parameter of the CPU to a determined result; adjusting a processing frequency of a GPU according to the determined result; and adjusting a resolution of displayed images according to the adjusted processing frequency of the GPU so as to display images.

Image display method and display system

The present invention discloses a backlight, a regulation method thereof, a regulation device and a display device. The backlight comprises a driving unit, a register, a PWM unit and a light-emitting unit, the PWM unit is connected between the driving unit and the light-emitting unit, and the register is connected to the PWM unit. The driving unit is used for converting a voltage signal to a primary driving signal; the register is used for defining a preset threshold value, which is the maximum value of duty ratio of a signal that the PWM unit outputs when performing a PWM process; the PWM unit is used for regulating duty ratio of the primary driving signal according to the preset threshold value and generating a regulated driving signal; and the light-emitting unit is used for emitting light when being driven by the regulated driving signal.
