Abstract
A display driving circuit comprises a display driving chip and a control unit. The display driving chip coupled to a display unit is for driving the display unit. The control unit is coupled to the display driving chip, for controlling the display unit to display the item information. The display driving chip controls the display driving circuit to operate in a normal mode or a power saving mode according to a light sensor. When the light sensor senses the light is not sufficient, turning off the display and turning off the power of related circuit to enter the power saving mode. In this way, the problem of power consumption at night or non-use of time can be solved, so as to effectively save the power.
