Description of the invention: [Technical field to which the invention pertains] The present invention relates to a button structure, and more particularly to a method of fabricating a light guide plate. [Prior Art] The button structure is one of the main input devices of the electronic device. Each button on the button structure usually has corresponding numbers, characters, phonetic symbols, input method roots and various function graphics, etc., so that the user can Enter data or perform various functions of the electronic device. Therefore, the button structure is an extremely important input device for electronic devices. Since the electronic device is in a well-lit environment, the user can clearly see the position of each button, and the problem of pressing the wrong button does not occur when the operation is pressed. In the absence of light or insufficient light, it is difficult for the user to operate the keys on the electronic device. Therefore, a backlight is disposed on the inner layer of the button structure, and the light generated by the backlight allows the user to clearly see the position of each button in a light-free environment, and the wrong button does not occur when the operation is pressed. The backlight used in the conventional button structure is composed of a light guide plate and a light-emitting diode. When the electronic device is activated, the light-emitting diode is turned into a party and the light is introduced from the front end of the light guide plate. The light guide plate projects light at the bottom of each button, so that the number or figure of the button surface can be displayed, and the user does not press the wrong button when performing the button operation in the no light environment. However, when the light of the light-emitting diode is introduced from the front end of the light guide plate to the rear end, the brightness of the light is gradually attenuated, resulting in the light guide plate. 200831965
