Problems solved by technology

[0004] Regardless of whether the user feels that the brightness of the display automatically adjusted by the portable electronic device is too bright or too dark, the user cannot adjust the display brightness of the display of the portable electronic device in the automatic brightness adjustment mode according to his own subjective visual experience. The action of brightening or dimming, on the contrary, makes the automatic adjustment function of display brightness unable to meet the actual needs of users, and even causes discomfort to the eyes of users when watching the screen

Abstract

The invention discloses a method for automatically adjusting brightness of a display and a portable electronic device. The method comprises the following steps: receiving a plurality of brightness sensing signals and calculating an average ambient illumination value based on the brightness sensing signals; receiving a user setting signal, wherein the user setting signal contains increase and decrease in value defined by the user; according to the average ambient illumination value and the increase and decrease in value defined by the user, finding a corresponding specific brightness control signal from a comparison table; and automatically adjusting the displaying brightness of the display according to the specific brightness control signal. According to the invention, the displaying brightness of the display can be automatically adjusted by utilizing ambient illumination sensed by an ambient light sensor.

Description

technical field [0001] The present invention relates to brightness adjustment of a display, in particular to a method for automatically adjusting the brightness of a display and a portable electronic device. Background technique [0002] In recent years, with the progress of light sensing technology, many advanced light sensing elements have been developed one after another and are widely used in various electronic products. For example, currently common portable electronic devices on the market, such as smart phones, notebook computers or tablet computers, can already use an ambient light sensor to sense the ambient illuminance and match the current backlight of the display. Brightness or in battery / charging mode, makes automatic adjustment of the display brightness of the monitor. [0003] Although portable electronic devices on the market can automatically adjust the display brightness of their displays, users still feel that there are some defects when actually using th...
