Description
Technical field
The present invention relates to back light model setting technology fields, and in particular to a kind of side entrance back module for realizing HDR subregion and
Liquid crystal display device.
Background technique
Backlight module is one of the primary clustering of panel of LCD, for providing sufficient brightness and being evenly distributed
Light source can normally show image.Backlight module can be divided into preceding light formula and two kinds of backlight type, and backlight type can be according to its scale
Classify it is required that being done with the position of fluorescent tube, and is divided into side entering type (i.e. side type enters light) and straight-down negative.
In order to realize the HDR display effect of high dynamic contrast, side type enters the backlight module and its liquid crystal of light at present
Show equipment by the way of the control of HDR multi partition, there are mainly two types of for HDR multi partition control mode：The first HDR square partition
For formula as shown in Figure 1, mostly using 1 lamp bar 3 greatly, 1 row's LED lamp bead is arranged in lamp bar 3 above, and LED lamp bead is taken more strings more and designed,
Wherein each serializer circuit, by individually controlling light on and off, as a subregion, how many parallel circuit in total of lamp bar 3 is just point how many
A subregion.Realize that a local dimming laterally or longitudinally is closed by the opening and closing of independent control subregion, this Local
The implementation of Dimming subregion is limited to the string and design of lamp bar 3 more, and the quantity for capableing of subregion is also seldom, the display of HDR
Effect is less desirable；Second of HDR partitioned mode is as shown in Fig. 2, 1 lamp bar 3 is provided with two rows of LED lamp beads, upper row above
LED lamp bead and lower row's LED lamp bead in vertical direction arranged in parallel, meanwhile, use two layers of light guide plate 2 instead and respectively correspond upper and lower row LED
Lamp bead enters light, wherein light-emitting surface height is consistent, corresponding leaded light because two rows of LED lamp beads are fixed on the same pcb board face
Plate 2 is also identical size design, is flushed in incidence surface port.Single LED lamp bead, if there is N number of parallel connection, so that it may
To realize N number of subregion, two rows LED lamp bead can realize N+N subregion in total, and two rows of LED lamp beads can realize string
And control, it is total can the region quantity of subregion have a larger increase than first way.However, there is also some bright for the second way
Aobvious defect：1) LED lamp bead arrangement is intensive, and the heat that every LED lamp bead distributes all concentrates on the top half of lamp bar 3, largely
Heat be accumulated at one piece, heat can not quickly be conducted by the aluminium extruded 1 that radiates, and seriously affect the LED lamp bead service life；2) because of string
And subregion is more, elongatedness is very big under pcb board, so that the height dimension of whole pcb board is excessive, will cause entire liquid crystal back in this way
Optical mode group or TV thickness can be very thick, can not embody side type and enter requirement of the light in terms of ultra thin dimensions, integrally seem heavy.
Summary of the invention
It is an object of the invention to aiming at the shortcomings in the prior art, and provide a kind of side entering type back for realizing HDR subregion
Optical mode group and the liquid crystal display device for using the backlight module, the side entrance back module is with enough HDR subregions
On the basis of, it not only solves the heat dissipation problem of multiple lamp bars and meets the thickness of entire liquid crystal display device on ultra thin dimensions
Demand.
The purpose of the present invention is achieved through the following technical solutions：
A kind of side entrance back module for realizing HDR subregion is provided, including heat dissipation aluminium extruded, be fixed on heat dissipation aluminium extruded leaded light

Several LED lamp beads being arranged in row being fixed on pcb board, the lamp bar are fixed on the side wall of heat dissipation aluminium extruded, and feature exists
In：The lamp bar and the light guide plate to match with the lamp bar are arranged on the pcb board of each lamp bar at least provided with two
There is row's LED lamp bead；
It is in upper and lower Heterogeneous Permutation between adjacent lamp bar, there are overlapping region, corresponding adjacent light guide plates between adjacent lamp bar
Between be also in upper and lower Heterogeneous Permutation, and the light-emitting surface of each lamp bar is between the incidence surface of the light guide plate of corresponding horizontal direction
Light mixing distance it is equal.
In above-mentioned technical proposal, the side wall of the heat dissipation aluminium extruded is disposed with the step of two-stage or more, the lamp bar point
It is not fixed on corresponding first order step surface.
In above-mentioned technical proposal, the cross section of the step is L-shaped.
In above-mentioned technical proposal, groove is formed between adjacent two-stage step, one end of each lamp bar is fixed on corresponding recessed
In slot.
The present invention also provides a kind of liquid crystal display devices, including backlight module and the liquid crystal being set on the backlight module
Panel, the backlight module are a kind of above-mentioned side entrance back module for realizing HDR subregion.
Beneficial effects of the present invention：
A kind of side entrance back module for realizing HDR subregion of the invention including heat dissipation aluminium extruded, is fixed on heat dissipation aluminium extruded
Light guide plate, the lamp bar for being set to light guide plate incident side and the optical diaphragm being set to above light guide plate, lamp bar include pcb board and
Several LED lamp beads being arranged in row being fixed on pcb board, lamp bar are fixed on the side wall of heat dissipation aluminium extruded, lamp bar and and lamp
The light guide plate that item matches is provided with row's LED lamp bead on the pcb board of each lamp bar at least provided with two；Adjacent lamp bar
Between be in upper and lower Heterogeneous Permutation, there are overlapping region between adjacent lamp bar, also in dislocation up and down between corresponding adjacent light guide plate
Arrangement, the light-emitting surface of each lamp bar is equal to the light mixing distance between the incidence surface of the light guide plate of corresponding horizontal direction, thus
Guarantee higher light light efficiency out.Using the above structure, more HDR zonal controls may be implemented in more than two lamp bars, reach
The HDR display effect of high dynamic contrast is deposited between adjacent lamp bar simultaneously as being in upper and lower Heterogeneous Permutation between adjacent lamp bar
In overlapping region, the height of pcb board single in this way can either meet the space of single lamp bar subregion cabling, and can make all lamps
The total height formed after item arrangement has biggish reduction compared to the sum of the lamp bar height of all quantity, so as to realize entire liquid
The thickness of brilliant backlight module is thinned；On the other hand, the heat of all lamp bars will not be concentrated excessively, can pass through the aluminium extruded that radiates
Side wall promptly guided.Therefore, side entrance back module of the invention is high dynamic to realize with enough HDR subregions
On the basis of the HDR display effect of state contrast, not only solves the heat dissipation problem of multiple lamp bars and meet entire liquid crystal
Demand of the thickness of showing device on ultra thin dimensions.
