Abstract
A display screen and a method for display control are provided in the disclosure. The display screen includes an emissive display assembly, a reflective liquid crystal display assembly, and a controller. The controller is configured to acquire a brightness value of current ambient light, and according to a variation in the brightness value of the ambient light, control the emissive display assembly to work to emit light for display, and/or control the reflective liquid crystal display assembly to work to use the ambient light for display.
Claims18
A display screen, comprising an emissive display assembly, a reflective liquid crystal display assembly, and a controller electrically connected with the emissive display assembly and the reflective liquid crystal display assembly;
- the controller being configured to acquire a brightness value of current ambient light, and according to a variation in the brightness value of the ambient light, selectively
- control the emissive display assembly to work to emit light for display;
- control the reflective liquid crystal display assembly to work to use the ambient light for display;
- or
- control the emissive display assembly to work to emit light for display, and control the reflective liquid crystal display assembly to work to use the ambient light for display,
- wherein the controller is configured to:
- control the emissive display assembly not to work and control the reflective liquid crystal display assembly to work to use the ambient light for display, when the brightness value is greater than or equal to a first preset brightness value;
- control the emissive display assembly to work to emit light for display and control the reflective liquid crystal display assembly to work to use the ambient light for display, when the brightness value is less than the first preset brightness value and greater than a second preset brightness value, wherein the second preset brightness value is less than the first preset brightness value;
- or
- control the emissive display assembly to work to emit light for display and control the reflective liquid crystal display assembly not to work, when the brightness value is less than or equal to the second preset brightness value.
A display screen, comprising an emissive display assembly, a reflective liquid crystal display assembly, and a controller electrically connected with the emissive display assembly and the reflective liquid crystal display assembly;
- the controller being configured to acquire a brightness value of current ambient light, and control one of the emissive display assembly or the reflective liquid crystal display assembly to work based on a comparison between the brightness value of the current ambient light and at least one preset brightness value.
A method for display control, applied to a display screen comprising an emissive display assembly and a reflective liquid crystal display assembly, the method comprising:
- acquiring a brightness value of current ambient light;
- and
- according to a variation in the brightness value of the ambient light, selectively
- controlling the emissive display assembly to work to emit light for display;
- controlling the reflective liquid crystal display assembly to work to use the ambient light for display;
- or
- controlling the emissive display assembly to work to emit light for display, and controlling the reflective liquid crystal display assembly to work to use the ambient light for display,
- wherein “according to the variation in the brightness value of the ambient light, selectively controlling the emissive display assembly to work to emit light for display, controlling the reflective liquid crystal display assembly to work to use the ambient light for display, or controlling the emissive display assembly to work to emit light for display and controlling the reflective liquid crystal display assembly to work to use the ambient light for display” comprises:
- controlling the emissive display assembly not to work and controlling the reflective liquid crystal display assembly to work to use the ambient light for display, when the brightness value is greater than or equal to a first preset brightness value;
- controlling the emissive display assembly to work to emit light for display and controlling the reflective liquid crystal display assembly to work to use the ambient light for display, when the brightness value is less than the first preset brightness value and greater than a second preset brightness value, wherein the second preset brightness value is less than the first preset brightness value;
- or
- controlling the emissive display assembly to work to emit light for display and controlling the reflective liquid crystal display assembly not to work, when the brightness value is less than or equal to the second preset brightness value.
