Abstract

The invention relates to portable electronic equipment, comprising a mainboard, a button shell covered on the mainboard and a display screen which is flush with the button shell. At least one light source is arranged on the mainboard, and a light guide element is arranged between the mainboard and the display screen. The light guide element comprises a light ingoing part, a light emitting part and a light guide part connecting the light ingoing part and the light emitting part. The light ingoing part is provided with an end surface aligned with the light source, and the end surface is used for receiving emergent light of the light source. The light emitting part is provided with a light emitting surface adhered with the display screen, and the light of the light source is emitted out to the display screen through the light emitting surface, and the light guide part is fixed on the button shell. In the portable electronic equipment, the light source is directly arranged on the mainboard, and another circuit board used for arranging the light source beside the display screen is omitted, so as to miniaturize the portable electronic equipment. In addition, the quantity of the circuit boards is reduced and the signal interference among a plurality of circuit boards can be effectively avoided.

Description

technical field [0001] The invention relates to an electronic device, in particular to a portable electronic device. Background technique [0002] A traditional mobile phone generally includes a display screen, a main board and a plurality of buttons connected to the main board of the mobile phone. The display screen is arranged on the surface of a backlight module. The backlight module includes an LED light source and a light guide plate with an exit surface. The LED light source is generally arranged on one side of the light guide plate through an independent circuit board. The independent circuit board It is electrically connected to the main board but separated from the main board. The light emitted by the LED light source is transmitted to the display screen through the light guide plate, and when the user presses a button, the motherboard obtains a signal and triggers the LED light source to emit light, thereby making the display screen bright. However, due to the ne...
