Detailed description of the invention
Fig. 1 is the schematic top plan view for illustrating the preferred embodiment of backlight module of the utility model；
Fig. 2 is the schematic side view for aiding in illustrating Fig. 1；And
Fig. 3 is the enlarged diagram that the frame of explanatory diagram 1 shows the amplification situation of part.
Specific embodiment
Relevant scope and technology contents in relation to the utility model, will be in the preferred embodiment below with reference to attached drawing
It is clearly presented in detailed description.Before being described in detail, it is noted that similar component be be identically numbered come
It indicates.
Figures 1 and 2 show that the preferred embodiment of the backlight module of the utility model.As depicted in figs. 1 and 2, backlight mould
Group includes optical sheet 2 and multiple light emitting diodes 3.Light emitting diode 3 is set to 2 lower section of optical sheet.Backlight module goes out light at it
Panel is arranged in position, thus constitutes display device.
Refering to fig. 1, optical sheet 2 have upper side edge 21, and with the spaced lower side 22 of upper side edge 21, wherein upside
Side 21 is the arc being bent upwards, and lower side 22 has left horizontal segment 221, right horizontal segment 222 and is connected to left horizontal segment 221
Between right horizontal segment 222 and the curved arc section 223 that is bent upwards.Therefore, there are two curved edges for the formation of optical sheet 2, wherein one
A curved edge is upper side edge 21, and another curved edge is located at lower side 22, as curved arc section 223.From the shape of optical sheet 2
Shape can be seen that this preferred embodiment and apply on non-rectangle optical sheet 2 (such as Vehicular instrument board etc.).
Light emitting diode 3 is in plurality of rows in 2 lower section of optical sheet, and near 3 edge of the light emitting diode of curved edge
Curved edge arranged in a manner of camber line.From depression angle shown in FIG. 1 it can be clearly seen that the upper limb of close optical sheet 2
Light emitting diode 3 along upper side edge 21 in arcuation arrange, and close to optical sheet 2 lower edge light emitting diode 3 along downside
The curved arc section 223 on side 22 is arranged in arcuation.
It illustrates, projection of every a line light emitting diode 3 on optical sheet 2 divides with upper side edge 21 and lower side 22
It is not formed with spacing, and every a line light emitting diode 3 axially arranges, adjacent another row light emitting diode 3 is then parallel to
Axially spaced-apart arrangement, and at least a line light emitting diode 3 and adjacent another row light emitting diode 3 is using axial direction as benchmark direction mistake
Position arrangement.
Refering to Fig. 3, since optical sheet 2 is that irregular shape should be first when arranging light emitting diode 3
Find out optical sheet 2 to arrange every a line light emitting diode 3 apart from overall length (L), that is, upper side edge 21 and lower side 22
Vertical range.The shape of optical sheet 2 according to the present embodiment, arrange every a line light emitting diode 3 apart from overall length (L) not
It is identical.It is then determined being sent out with the pitch (p) of two adjacent LEDs 3 in a line light emitting diode 3 and every a line
The reserved distance (D1, D2) of about 3 optical diode.Then, (L-D is calculated1-D2)/p=Y, since Y may be not integer, because
This is after carrying out unconditional carry rounding to Y so that it becomes N.Then, L/N=P is calculated.Wherein, P is with a line light emitting diode
The spacing of two adjacent LEDs 3 in vertical direction in 3, and 3 quantity of light emitting diode of the row is (N+1).
From above calculation it is found that in same a line light emitting diode 3, the adjacent light emitting diode 3 of any two
Arrangement spacing it is identical.Since upper side edge 21 is the design for being completely in arcuation, between the arrangement of every a line light emitting diode 3
Away from the arrangement spacing for being different from adjacent rows light emitting diode 3.
Via the above preferred embodiment it is found that the backlight module of the utility model can make each row by previous designs
The number of the arrangement of light emitting diode 3 changes depending on it apart from overall length, and can make two line positions in multirow light emitting diode 3 in
The light emitting diode 3 of end is arranged along upper side edge 21 and lower side 22, and can make at least a line light emitting diode 3 with
Adjacent another row light emitting diode 3 is dislocation arrangement, so that the edge for efficiently reducing the optical sheet 2 of irregular shape generates
The chance of shadow, therefore the purpose of this utility model can be reached really.
The above is only the preferred embodiment of the present invention, and the implementation model of the utility model should cannot be limited with this
It encloses, i.e., generally according to simple equivalent changes and modifications made by the patent claim and description of the utility model, all
Still belong to the patent covering scope of the utility model.
