Description of the Invention: [Technical Field] The present invention relates to a portable electronic device, and more particularly to a portable electronic device in which a backlight and a light source are shared by a screen. [Prior Art] In recent years, with the development of semiconductor technology and network communication technology, various portable electronic devices, such as Pers〇nal Digital Assistance (PDA) and mobile phones, have not only The market trend of light and short is striding forward. 'The concept of energy saving and energy saving is also gradually reflected in the design of portable electronic devices, in order to meet the needs of the consumer. Generally speaking, the liquid crystal module (LCD module 'LDM) and the button between the portable electronic device are configured to be configured to block and shield the light blocking function of the light function, so that the backlight source and the keyboard of the liquid crystal module are The light emitted by the backlight source does not affect each other. Since the brightness of the light source of the liquid crystal module is relatively high, the design of the light blocking element is originally intended to prevent the light source of the liquid crystal module from penetrating to the area of the keyboard and interfere with the illumination of the keyboard. However, because the light emitted by the backlight source of the liquid crystal module is not easily blocked by the light blocking element, the light source of the keyboard does not need to be too strong, and only the text symbol on the keyboard can be displayed in the dark to satisfy the user. demand. Therefore, if a portable electronic device using a backlight source of a liquid crystal module and a keyboard is designed, the cost and space of the portable electronic device can be saved, and the backlight source used in the portable electronic device can be reduced.
