DISPLAY DRIVING CIRCUIT-BASED TERMINAL DEVICE

Title:

DISPLAY DRIVING CIRCUIT-BASED TERMINAL DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/168949

Kind Code:

A1

Abstract:

A display driving circuit (2022) based terminal device, which is used for solving the problem in which a portion of the current of the display driving circuit (2022) is released by a PMIC. The terminal device comprises: a power circuit (201), a screen module (202), a switch circuit (203) and a control circuit (204), the screen module (202) comprising a display panel (2021) and the display driving circuit (2022). The switch circuit (203) is coupled between the power circuit (201) and the display panel (2021), the control circuit (204) is coupled with the switch circuit (203), and the power circuit (201) is also coupled with the display driving circuit (2022). When controlling the display panel (2021) to be in a screen-off display mode, the control circuit (204) is used to control the switch circuit (203) to be in an open state so as to disconnect the connection between the power circuit (201) and the display panel (2021), which enables the display driving circuit (2022) to provide power to the display panel (2021). When controlling the display panel (2021) to be in a screen-on display mode, the control circuit (204) is further used to control the switch circuit (203) to be in a closed state so as to enable the power circuit (201) to provide power to the display panel (2021).
