Description
Technical field
The utility model system has about a kind of portable electronic devices, and especially a kind of its comprises the portable electronic devices with two exiting surface backlight modules.
Background technology
Along with the progress of science and technology, various portable electronic devices, Wearable device etc., constantly weed out the old and bring forth the new, these electronic installations all must possess basic lighting function, using as indicating, illuminate, the purposes such as luminous, because backlight module (Back Light Module, BLM) has slimming, can produce the advantages such as area source, therefore BLM start by a large number be used in widely on various electronic installation as light emitting source.
As single with regard to backlight module the object that illuminates distinguish, existing BLM generally can be divided into two classes: for illuminating the white type back light module of display, or display backlight module (display-use BLM), and for the monochromatic type that illuminates non-display device or polychrome type backlight module, or non-display backlight module (non-display-use BLM); For display backlight module, because LCD display inherently possesses colored filter, so it is photochromic based on white light that class backlight module sends, after the colored filter Collaboration configured with LCD display again, each pixel of display is made independently to produce different photochromic formation picture or image.
But not display backlight module; such as: the keyboard back light module illuminating the Keysheet module of protective cover of keyboard; it is photochromic that this type of backlight module sends, and is not defined as white light; but also can be white light; it is photochromic is various possible photochromic, such as: it is photochromic that cold light is blue, cold light is red etc., and its photochromic fashion and popular also can taken into account adopted usually; in this type of backlight module, configuration is multiple usually can send different photochromic light source, makes backlight module can become monochromatic type or polychrome type backlight module.
