Abstract
A display control method, a display control module and a display device. The display control method is applied for a display device with a display panel and a data processing circuit, and includes: according to a to-be-displayed picture, detecting, by a black-screen area detection circuit, a black-screen display area of the display panel in an always-on mode; controlling, by a logic control circuit, to stop providing display data corresponding to the black-screen display area, for the data processing circuit. The display data corresponding to the black-screen display area included in the to-be-displayed picture is black-screen display data.
Claims20
A display control method for a display device with a display panel and a data processing circuit, comprising:
- according to a to-be-displayed picture, detecting, by a black-screen area detection circuit, a black-screen display area of the display panel in an always-on mode;
- controlling, by a logic control circuit, to stop providing display data corresponding to the black-screen display area, for the data processing circuit;
- wherein the display data corresponding to the black-screen display area included in the to-be-displayed picture is black-screen display data.
A display control module for a display device with a display panel, a data processing circuit and a memory storing display data corresponding to a to-be-displayed picture, comprising:
- a black-screen area detection circuit configured to, when the display panel is in an always-on mode, detect a black-screen display area of the display panel, according to the to-be-displayed picture;
- and
- a logic control circuit configured to, when the display panel is in the always-on mode, control the memory to stop providing display data corresponding to the black-screen display area, for the data processing circuit;
- wherein the display data corresponding to the black-screen display area included in the to-be-displayed picture is black-screen display data.
A display device, comprising:
- a display panel, a memory, a data processing circuit and a display control module;
- wherein the memory stores display data corresponding to a to-be-displayed picture;
- the display control module includes:
- a black-screen area detection circuit configured to, when the display panel is in an always-on mode, detect a black-screen display area of the display panel, according to the to-be-displayed picture;
- and
- a logic control circuit configured to, when the display panel is in the always-on mode, control the memory to stop providing display data corresponding to the black-screen display area, for the data processing circuit;
- wherein the display data corresponding to the black-screen display area included in the to-be-displayed picture is black-screen display data.
