An exemplary low power consumption circuit includes a microprocessor, a power supply switch module and a main circuit module. The microprocessor is capable of outputting a power control signal and changing a pulse characteristic of the power control signal when the microprocessor switches from a first working mode to a second working mode. The power supply switch module is capable of outputting a power supply signal. The power supply switch module is electrically coupled to the microprocessor to receive the power control signal and thereby modulates a duty cycle of the power supply signal according to a change of the pulse characteristic of the power control signal. The main circuit module is electrically coupled to the power supply switch module to receive the power supply signal and operative with energy provided by the power supply signal. Moreover, a method for reducing power consumption is also provided.

Low power consumption circuit and method for reducing power consumption

An array substrate includes scan lines and data lines defining pixel structures. Each pixel structure includes a first TFT, a second TFT and a pixel electrode. The first TFT includes a first gate connected to the scan line, a first source disposed above and partially overlapping the first gate, and a first drain disposed above the first gate. An end of the first source is connected to the data line. The first drain has at least one first concavity in which the first source is disposed partially. The second TFT includes a second gate connected to the scan line, a second source disposed above the second gate and connected to the first drain, and a second drain disposed above and partially overlapping the second gate. The second source has at least one second concavity in which the second drain is disposed partially. The pixel electrode connects to the second drain.
