The result is outputted in an electronic split 1〇〇. In a preferred embodiment, when the detected ratio is greater than a predetermined brightness ratio. After the brightness calculation module 204 notifies the electronic device 100, the user is notified through the screen 105 to adjust the brightness of the screen. For example, a dialog box will pop up, such as "The LCD is very light, please adjust it." (Fig. 2) ' Ask the user if they want to turn down the brightness to achieve the warning. Finally, the user decides whether the brightness of the money screen needs to be turned up or down. In another preferred embodiment, the electronic device 10 further includes a screen brightness illuminating module (not shown). The brightness adjustment module adjusts the brightness value of the current screen 105 according to a predetermined brightness ratio, so that the current brightness ratio obtained by adjusting the current screen brightness value and the current external light brightness value is equal to the predetermined brightness ratio. In still another preferred embodiment, the brightness adjustment device 200 further includes a device (not shown). When the party s is connected to the electronic device, the predetermined brightness ratio can be adjusted by the setting module through the electronic device 100. In addition, in another preferred embodiment, the setting module can be disposed in the electronic device 100 instead. When the brightness adjusting device 200 is connected to the electronic device 100, the electronic device 100' can be transmitted to adjust the predetermined brightness ratio. In the above embodiment, the brightness adjusting device 200 is preferably a flash drive. In the above embodiment, the electronic device 100 is preferably a notebook computer. Referring to FIG. 3, a method for adjusting the brightness of a screen according to a preferred embodiment of the present invention includes at least the following steps: First, storing a predetermined ratio of brightness in a flash memory, which is a predetermined screen. The ratio of the brightness value to the brightness value of the external light (coffee); the screen brightness detection module is fine on the screen brightness of the current electronic device (coffee); the current screen brightness value f is the brightness of the module (3); Measure the current external light brightness (S2G4); transmit the current external light brightness value to the brightness comparison module (5205) W brightness ratio module calculates the ratio of the target screen brightness value to the current external first line acceptance value, and judges Whether it is greater than the predetermined brightness ratio (5206), and, right, the electronic device (8) is notified of the determination result; if no, the process returns to step S202 to continue the detection. In a preferred embodiment of the present invention, after the step of notifying the determination result to the device (S207), the electronic device is further included to display the determination result on the screen. Finally, the user can decide whether to adjust the brightness of the screen of the electronic device according to the warning message. In another preferred embodiment of the present invention, after the step of notifying the electronic device of the determination result (S207), the method further comprises: adjusting the current screen brightness value to adjust the ratio of the adjusted current screen brightness value to the current external light brightness value. 'The ratio of the predetermined screen brightness value to the external light brightness value is equal. In still another preferred embodiment of the present invention, before the step (3201) of storing a predetermined luminance ratio in a flash memory, the setting of the predetermined luminance ratio is further included. ° In the above embodiment, the photosensitive module is preferably a photosensitive module.
