Abstract

The invention provides a low-power display method for a portable device and a portable device. The portable device includes an ambient light sensor to detect ambient light around the portable device to generate a first sensing signal; a control module for generating a display content to be displayed on the display panel and collecting the first sensing signal from the ambient light sensor, wherein the control module controls the display panel to enter a low power mode in response to the first sensing signal. The present invention provides a low-power display method for a portable device and a portable device which can reduce the display power consumption of the portable device and prolong the battery life.

Description

[0001] 【Technical field】 [0002] The present invention relates to low-power display technology, in particular to a low-power display method for a portable device and the portable device. [0003] 【Background technique】 [0004] As technology advances, transflective or reflective displays have been used in portable devices to save power. These types of displays reflect ambient light (eg, sunlight) as their backlight. It does not need to use any power on the backlight when the ambient light is sufficient. [0005] Generally speaking, due to the excellent display performance of the transflective display screen or the reflective display screen, it is usually implemented by a liquid-crystal display (LCD) or an organic light-emitting diode (OLED) display. However, an LCD or OLED display requires power to refresh the display, and it consumes more power and reduces battery life. Therefore, a portable device is needed to solve the above-mentioned problems. [0006] 【Content of inve...
