Abstract
The invention provides a backlight module and a display device with the backlight module. The backlight module comprises a light guide plate and at least two light emitting units, wherein the light guide plate has at least two adjacent projections and gaps; the gaps are positioned among the projections; and the at least two light emitting units are respectively corresponding to the projections. The invention further provides the display device, wherein a display panel is arranged on the backlight module. According to the backlight module and the display device, the light emitting units are respectively corresponding to the projections of the light guide plate, so that the hot spot phenomenon can be reduced. In addition, as electronic devices are accommodated in the gaps among the projections of the light guide plate, a reverse folding area of a flexible substrate can be shortened, and the edge of the module is reduced to achieve the size decreasing effect.
Description
Technical field
The present invention is related to a kind of backlight module and the display device with this backlight module.
Background technology
Backlight module is an important devices of LCDs, is generally placed upon under liquid crystal panel
Side.And in order to reduce the thickness of backlight module, be the most mostly that the light source of backlight module is arranged on leaded light
The side of plate.
With reference to Fig. 1, it is known that LCDs includes light guide plate 110, is arranged on display panels 120
Lower section, wherein display panels 120 has viewing area 122.The side of light guide plate 110 is arranged
There are luminescence unit 130, e.g. light emitting diode (LED).Flexible substrate 140, carries electronics device
Part 150, wherein one end of flexible substrate 140 extends to the lower section of light guide plate 110, and the other end then prolongs
Extend on display panels 120, and the wafer 160 being electrically connected on display panels 120.
But, owing to light emitting diode is point source of light, if not through Homogenization Treatments, emitted by it
Light be concentrated in the side of light guide plate 110, without uniformly dispersing at the light of whole light guide plate 110
Exit facet, therefore causes light to be relatively concentrically formed the light source bright spot that tool graininess is assembled, creates so-called
" headlight " (hot spot) phenomenon.
Additionally, aforesaid flexible substrate 140 is connected to light guide plate 110 from display panels 120 bending,
Place to electronic device 150 with a reserved margo frontalis length, but this will result in the waste used spatially.
In view of this, just there is a need to propose a kind of scheme, to solve the problems referred to above.
Summary of the invention
It is an object of the invention to provide a kind of backlight module.
For reaching above-mentioned purpose, the backlight module of the present invention includes: light guide plate, has at least two adjacent
Projection and gap, wherein said gap is between described projection；And at least two luminescence unit, point
Dui Yingyu described protruding setting.
Another object of the present invention is to provide a kind of display device, wherein display panel configurations is in aforesaid
On backlight module.
Backlight module according to the present invention and display device, wherein the most corresponding light guide plate of luminescence unit is convex
Rise and arrange, therefore can reduce headlight phenomenon.Further, since electronic device is contained in light guide plate projection
Between gap in, therefore can shorten the opisthotonos region of flexible substrate so that the margo frontalis length of module is contracted
Subtract, reach to reduce effect of volume.
In order to above and other purpose, feature and the advantage of the present invention can be become apparent from, cited below particularly
Inventive embodiments, and coordinate appended diagram, it is described in detail below.

Detailed description of the invention
With reference to Fig. 2 and 3, the backlight module of the present invention include light guide plate 210, multiple luminescence unit 230,
Flexible substrate 240 and multiple electronic device 250.Multiple protruding 212 it are formed with on the side of light guide plate 210,
Gap 214 is defined between two the most adjacent projections 212.Luminescence unit 230 can be light-emitting diodes
Pipe (LED), is arranged in the face of protruding 212 respectively.Electronic device 250 can be active (active)
Or the electronic device of passive type (passive), it is respectively contained in gap 214.Flexible substrate 240
One end carrying electronic device 250, and be connected to the lower section of light guide plate 210, and with protruding 212 and luminous
Unit 230 is overlapping.
Refer to Fig. 4, the display device of the present invention includes the backlight module shown in Fig. 2 and display surface
Plate 220, e.g. display panels, be arranged in the top of backlight module, namely be arranged in light guide plate
210 with the top of luminescence unit 230.The flexible substrate 240 of carrying electronic device 250 is except one end even
Receiving outside backlight module, also bending makes the other end be connected to display floater 220, and is electrically connected to display
Wafer 260 on panel 220.Display floater 220 has viewing area 222, wherein luminescence unit 230
Relatively electronic device 250 is further from viewing area 222.
Backlight module according to the present invention and display device, the wherein the most corresponding light guide plate of luminescence unit 230
The projection 212 of 210 is arranged.In the present embodiment, because protruding 212 is elongated structure, and have
The effect of similar waveguide (waveguide), can be delivered to the light that luminescence unit 230 penetrates farther out
Position.Owing to the light of luminescence unit 230 injection can be delivered to remotely, it is not concentrated in leaded light
The light inlet of plate 210 and form bright spot, therefore reduce known " headlight " (hot spot) phenomenon.
Backlight module according to the present invention and display device, owing to electronic device 250 is contained in protruding 212
Between gap 214 in, therefore can shorten the opisthotonos region of flexible substrate 240.So, refer to
Fig. 5, compared to known LCDs, the display device of the present invention can make the margo frontalis length of module be able to
Reduction, reaches to reduce effect of volume.
In addition, owing to electronic device 250 is contained in the gap 214 between protruding 212, please
With reference to another embodiment of Fig. 6, as seen from the figure, luminescence unit 230 in the display device of the present invention
With distance D2 of the viewing area 222 of display floater 220, the luminous list more than in known LCDs
Distance D1 of the viewing area 122 of unit 130 and display panels 120.Therefore, compared to known
LCDs, the setting of the luminescence unit 230 of the present invention can be away from the viewing area of display floater 220
222, thereby make mixed light be more uniformly distributed, " headlight " phenomenon can be reduced further, promote image quality
Performance.
Although the present invention is disclosed by previous embodiment, but it is not limited to the present invention, any
There is the technical staff of usual knowledge in the technical field of the invention, without departing from the present invention spirit and
In the range of, when making various changes and amendment.Therefore protection scope of the present invention is when regarding appended right
Require to be defined in the range of standard.
