Abstract
A screen switching method for an electronic apparatus includes an e-Paper and a display having a backlight module. The e-Paper and the display are used to show an image signal. The screen switching method includes determining whether a brightness value at which the backlight module is set exceeds a threshold value, controlling the display to show the image signal if the brightness value of the backlight module exceeds the threshold value, and controlling the e-Paper to show the image signal if the brightness value of the backlight module does not exceed the threshold value. An electronic apparatus implementing the screen switching method is also disclosed.
Claims18
A screen switching method for an electronic apparatus including an e-Paper and a display having a backlight module, the e-Paper and the display being used to show an image signal, said screen switching method comprising:
- a) determining whether a brightness value at which the backlight module is set exceeds a threshold value;
- b) controlling the display to show the image signal if the brightness value of the backlight module exceeds the threshold value;
- and
- c) controlling the e-Paper to show the image signal if the brightness value of the backlight module does not exceed the threshold value.
An electronic apparatus for showing an image signal, said electronic apparatus comprising:
- an e-Paper;
- a display including a display panel and a backlight module for providing a light source;
- a brightness adjustment module for setting a brightness value of said backlight module;
- a control module for selecting to send the image signal to either said display or said e-Paper;
- and
- a determining module for determining whether the brightness value exceeds a threshold value, said determining module controlling said control module to send the image signal to said display for showing thereon if the brightness value exceeds the threshold value, said determining module controlling said control module to send the image signal to said e-Paper for showing thereon if the brightness value does not exceed the threshold value.
