Problems solved by technology

[0006] However, when the user uses the liquid crystal display device 1 under sunlight, the problem of insufficient brightness of the panel is likely to occur, which causes troubles for the user.
In addition, if this problem is overcome by enhancing the brightness of the light-emitting component 13, another problem of too much power consumption will occur.

Abstract

The invention relates to an electronic device, comprising a shell, a display panel and a backlight module. The shell is provided with at least an opening; the display panel is arranged on the shell and used for displaying; the backlight module is arranged inside the shell and used as the light source of the display panel; the backlight module is provided with at least a lumination component, a light guide plate and at least a light pipe, wherein, the light guide plate leads the light beam emitted by the lumination component to be guided into the display panel; the light pipe is provided with an optical input terminal and an optical output terminal; the optical input terminal is arranged at the opening of the shell so as to be exposed in the air; and the optical output terminal is arranged at the side edge of the light guide plate so as to lead the light pipe to guide the external environmental light to the light guide plate.

Description

technical field [0001] The present invention relates to an electronic device, in particular to an electronic device that can use external ambient light as a light source. Background technique [0002] The liquid crystal display device is composed of a liquid crystal display panel and a backlight module. Since the liquid crystal itself does not emit light, the backlight module provides the light source required by the liquid crystal display panel, so that images can be displayed. [0003] Such as figure 1 As shown, a known liquid crystal display device 1 includes a casing 11, a light guide plate 12, a light-emitting component 13, a plurality of optical films 14, and a liquid crystal display panel 15, wherein the light guide plate 12 and the light-emitting component 13 are used as For backlight module. [0004] Here, the casing 11 is composed of an upper cover 111 and a lower cover 112 , and the light guide plate 12 , the light emitting component 13 , the optical film 14 and...
