Problems solved by technology

However, high-brightness light-emitting diodes generate more heat during work, and the covers of portable electronic devices such as notebook computers are usually thinner. Cannot effectively discharge the cover, which will cause the portable electronic device to be unable to maintain the optimum operating temperature for a long time to exert its maximum performance

Abstract

A portable electronic device is provided, which comprises a main body, a cover body, a pin-jointed unit, an LCD panel and a backlight module. The main body is connected with the pin-jointed unit by the cover body and the LCD panel is fixed on the cover body, wherein, the backlight module comprises a light source, an optical fiber accessories and a light guide plate. The light source is in the main body, the light guide plate is in the cover body and the optical fiber accessories is used for transmitting the light generated by the light source to the light guide plate to illumine the LCD panel. The portable electronic device is mounted in the main body via the backlight module. The relatively larger thermal dissipation space of the main body is propitious to effectively spill out the thermal generated by the light source, and is further good for permanently maintaining a best operating temperature of the portable electronic device so as to bring the greatest efficiency into full play.

Description

technical field [0001] The invention relates to a portable electronic device, in particular to a portable electronic device with a backlight module. Background technique [0002] At present, portable electronic devices such as notebook computers and personal digital assistants (Personal Digital Assistant, PDA) are widely used because of their portability. Such portable electronic devices generally include a main body, a cover, a hinge, a liquid crystal panel and a backlight module. The main body and the cover are pivoted together via the pivot. The main body is provided with a motherboard and a radiator; the motherboard is provided with electronic components such as a CPU, and the radiator is used to dissipate heat from the motherboard. The liquid crystal panel is arranged on the cover. The backlight module is arranged in the cover body to provide backlight for the liquid crystal panel; the backlight module usually includes a cold cathode fluorescent lamp (Cold Cathode Fl...
