When the cover is opened, the lighting lamp is matched with the light entrance. The emitted light can be incident into the light guide plate from the light entrance to provide a backlight source for the LCD panel display. Compared with the conventional technology, the portable electronic device with lighting function of this creation utilizes the lighting lamp on the body to match the light inlet on the cover, so that the lighting lamp that is known to provide good results for the LCD display of the device is provided. The backlight light source can reduce the manufacturing cost of the portable electronic device with lighting function. [Embodiment] The portable electronic device with lighting function of the present invention may be a mobile phone, a PDA, etc. This embodiment uses a mobile phone as an example for description. Please refer to page-. The mobile phone of the present invention includes a main body], a cover body 2 and a hinge 3, and the main body 1 and the cover body 2 are rotationally connected through the hinge 3, so that the cover body 2 can be opened and closed relative to the main body 1. Please refer to the second figure and the third figure in combination. The body 丨 includes a key 7, a housing 11, a battery 12, a lighting lamp 8 and a lighting switch 10, and a lighting circuit (not shown) is provided in the housing n. In order to provide electrical connection for the lighting lamp 8, the switch 丨 〇 and the battery 丨 2 and realize related functions. The illuminating lamp 8 is long or narrow, or is arranged by a plurality of point light sources, and is arranged at the connection between the body 1 and the hinge 3

Page 6 M260952 V. Creative Instructions (3) End 'is located below the hinge 3, and the lighting lamp 8 is embedded in a slot (not labeled) on the housing 11. The lighting lamp 8 may be a light emitting diode (LED, Light

Emitting Diode) or Cold Cathode Fluorescent Lamp (CCFL). The battery 12 provides power for the mobile phone and also serves as the power source for the lighting lamp 8. The lighting lamp switch 10 is provided on one side of the main body 1 and is used to control the lighting lamp 8 on and off. Carcass 2 includes an LCD (Liquid Crystal Display) display 4 and a casing 13 ′ The LCD display 4 is disposed on the casing 13. The LCD display 4 includes an LCD panel 5 and a light guide plate 6, wherein the light guide plate 6 is located below the LCD panel 5. The LCD panel 5 is exposed on the surface of the cover 2. The connecting end of the cover 2 and the hinge 3 is provided with a narrow light entrance 9 corresponding to the lighting lamp 8. A transparent protective device such as a lens, glass, etc. is provided at the narrow light entrance 9 to carry out the light guide plate 6. protection. When the mobile phone is in a closed state, the illuminating lamp 8 is exposed at one end of the mobile phone and can be used as a flashlight, which is convenient for the user to temporarily illuminate in the dark. When the mobile phone is in an open state, the cover 2 and the main body 1 are on the same plane, the lighting lamp 8 is aligned with the light entrance 9, and the lighting switch 1 is turned on. The light emitted by the lighting lamp 8 is incident on the light guide plate 6 Therefore, the illuminating lamp 8 can be used as a light source of the light guide plate 6, and the light guide plate 6 can be used as a light source for the LC1) panel 5 to display information and provide a backlight light source. It can be understood that the lighting switch 10 can be set as a button on the body! The user can control the lighting on and off by pressing the keys. In addition, the settings of the illumination lamp 8 and the light entrance 9 can also be changed accordingly, as long as the mobile phone is on, one of them can be combined to achieve an L c D display.
