Problems solved by technology

[0003] However, the disadvantage of electronic paper is that in a dark environment, the electronic paper cannot be clearly displayed due to insufficient brightness outside, making it difficult for users to read. Therefore, an electronic device that combines electronic paper and a liquid crystal display has been launched on the market, allowing users to You can choose to use electronic paper or liquid crystal display as the display screen, but using liquid crystal display as the display screen is still a relatively power-hungry choice after all.

Abstract

A screen switching method is applied to an electronic device. The electronic device has an electronic paper for displaying a picture signal and a display with a backlight module. The method includes determining whether a brightness value set by the backlight module exceeds A critical value, if yes, the display will display the image signal; if not, the electronic paper will display the image signal.

Description

technical field [0001] The present invention relates to a screen switching method and an electronic device, in particular to a screen switching method for screen switching based on the light source intensity of a backlight module and an electronic device for screen switching based on the light source intensity of the backlight module. Background technique [0002] As publishers promote the digitization of books, more electronic publications will come out in the future, making the application of electronic paper (e-Paper) more and more important, because e-paper does not need to have a self-illuminating light source. The reflection of external ambient light is used as the display light source, which meets the requirements of environmental protection and energy saving, and users do not need to watch a display with a self-illuminating light source for a long time, which can provide users with a more comfortable reading environment. [0003] However, the disadvantage of electron...
