Example Embodiment

[0024] The screen brightness adjustment device and the method for adjusting the screen brightness of the electronic device of the present invention will now be described in detail with reference numerals, and preferred embodiments are listed as follows:

[0025] Please refer to FIG. 1, which shows a brightness adjusting device 200 according to a preferred embodiment of the present invention, which is externally connected to an electronic device 100 and has a screen 105. The brightness adjustment device 200 includes a flash memory 201, a screen brightness detection module 206, a light-sensing module 202, and a brightness comparison module 204. The flash memory 201 is used to store a predetermined brightness ratio, which is a ratio of a predetermined screen brightness value to an external light brightness value. The screen brightness detection module 206 is used to detect the brightness of the screen 105. The photosensitive module 202 is used to detect the brightness of different am...

Abstract

The present invention discloses a screen brightness adjusting device applied to an electronic device. The screen brightness adjusting device comprises a flash memory, in which a prescribed brightness ratio, i.e. a prescribed brightness value ratio of the screen to the outside light, is stored; a screen brightness detection module used for detecting the present screen brightness of the electronic device; a light sensing module used for detecting the present brightness of the outside light; and a brightness comparing module, which is connected to the flash memory, the screen brightness detection module and the light sensing module and is used for calculating the present brightness value ratio of the screen to the outside light to obtain the present brightness ratio and compare with the present brightness ratio with the prescribed brightness ratio. If the present brightness ratio is larger than the prescribed brightness ratio, the comparison result is submitted to the electronic device. In addition, the present invention discloses a method for adjusting the screen brightness of the electronic device.

Description

technical field [0001] The present invention relates to a screen brightness adjusting device and a method for adjusting the screen brightness of an electronic device, in particular to a device which can automatically detect the brightness of light and transmit it to an electronic device to adjust the screen brightness of the electronic device and its adjusting electronic device. How to set screen brightness. Background technique [0002] With the widespread use of electronic devices such as notebook computers, such portable electronic devices have become indispensable and important tools in life and work. However, for example, when using a notebook computer, frequent movement is obviously necessary, but for different places of use, the brightness of the light provided by the external environment will also be different, such as offices, laboratories, conference rooms, production lines, etc. , because the ambient light varies greatly, so when using a notebook computer, the br...
