The display comprises the backlight module.
Description
Technical field
The present invention relates to a kind of display and backlight module thereof, particularly relate to the arrangement mode of fluorescent tube in the backlight module.
Background technology
See also Fig. 1, Fig. 2, Fig. 2 A, the backlight module 10 of its existing display comprises backboard 11, bottom surface 12, U type fluorescent tube 13 and tube support seat placement 14, shown in Fig. 2 A, tube support seat (not illustrating) is arranged at tube support seat placement 14 in order to support U type fluorescent tube 13, can obviously find out in the drawings, the arrangement mode of U type fluorescent tube 13 is set up on the backboard 11 in the mode that lies low for being parallel to bottom surface 12 in the existing backlight module 10.
Development with present display; the demand of display trends towards big molded dimension now; to satisfy consumer demand; if only will have the arrangement mode of U type fluorescent tube in the backlight module 10 now is applied in large-sized backlight module; usually can't make display have enough briliancy and the necessary brightening piece (indicating) that increases in addition; brightening piece not only can increase cost of manufacture; and be applied in the backlight module 10 of high heat; regular meeting is because the factor of high heat causes brightening piece to produce gauffer; and cause display frame not good; how in the limited space of backlight module, it is the problem that desire of the present invention solves that enough brightness of large-sized monitor and preferable display effect are provided.
Summary of the invention
In order to improve above-mentioned shortcoming, the invention provides a kind of display and backlight module thereof.Backlight module comprises a tube support seat, a backboard and at least one U type fluorescent tube, this backboard comprises a bottom surface, and U type fluorescent tube is fixed on this backboard, and these both ends and this bend limit a fluorescent tube plane, and each this fluorescent tube plane all presss from both sides a pitch angle with this bottom surface.
It should be noted that in the first embodiment of the present invention, when the number of U type fluorescent tube when being a plurality of, this each U type fluorescent tube is for being staggered.
It should be noted that in the second embodiment of the present invention, when the number of U type fluorescent tube when being a plurality of, this each U type fluorescent tube is for waiting to arrangement.
It should be noted that in the third embodiment of the present invention, backlight module more includes at least one linear pattern fluorescent tube, this linear pattern fluorescent tube places this U type fluorescent tube below and overlaps with this U type fluorescent tube.
For above and other objects of the present invention, feature and advantage can be become apparent, hereinafter enumerate preferred embodiment especially, and cooperate appended icon, be described in detail below.
