Description
Technical field
The utility model relates to a kind of liquid crystal indicator and module backlight thereof, particularly relates to a kind of liquid crystal indicator and side-light type module backlight thereof that fluorescent tube is joined in twos.
Background technology
General liquid crystal indicator mainly is to comprise a liquid crystal display and a module backlight, and module wherein backlight roughly can be divided into two types of straight-down negative (direct type) module backlight and side-light type (side-edgetype) modules backlight again.
Yet no matter be the module backlight of which kind of kenel, all need be driven luminescence unit in the module backlight by at least one drive circuit board, at present Chang Zuowei luminescence unit be to be cathode fluorescent tube, and be that a high-voltage driven signal that provides via drive circuit board is driven in order to the driven for emitting lights unit.
As shown in Figure 1, be generally luminescence unit 11,12 (cathode fluorescent tube) and drive circuit board 14 can be connected and assemble smoothly, it is one high pressure resistant and have the connecting line 13 of a splicing ear 131 that the dealer can be electrically connected in the electrode tip 111,112,121,122 of luminescence unit 11,12, is linked to a splicing ear 141 of drive circuit board 14 again via the splicing ear 131 of connecting line 13.At this moment, drive circuit board 14 drives the high-voltage driven signal of exporting in loop 142 by one and can be sent to luminescence unit 11,12 and driven for emitting lights unit 11,12 in addition via splicing ear 141, splicing ear 131 and connecting line 13 respectively.
