Abstract
The utility model is that a kind of LED shields liquid crystal display die set comprehensively, and the liquid crystal display die set includes light guide plate and light source, it is characterised in that：The light source be two pieces or more LED area light source and close composition, belong to the correlative technology field of liquid crystal display die set.Purpose be from provide it is a can from be addressed on source in existing product to the dependence of light guide plate, to the restricted, brightness of LED quantity not enough, have black surround area and assembling when product yield the problems such as a kind of LED shield liquid crystal display die set comprehensively.
Description
Technical field
The utility model relates to a kind of LED liquid crystal display die set, especially a kind of LED shields liquid crystal display die set comprehensively.
Background technique
The illumination mode of existing LCM mould group directs the light to entire light guide plate area by light guide plate with lateral LED light source leaded light
Domain.This technology has following technology to be restricted：Requirement for light guide plate is extremely high, so that the manufacture craft of light guide plate is very severe
It carves.In addition it while is also limited by performance of light guide plate etc., because in the case of normal volume production, the uniform performance of light guide plate
In 75% to 80%, so that the uniformity of light guide plate is extremely limited to.Furthermore the LED quantity of light guide plate carrying is also by certain
Limitation because current liquid crystal display die set is all that side light source is guide-lighting, and the size of side light guide plate is limited, what side was put
LED quantity is naturally also to be subject to certain restrictions, and because LED quantity is subject to certain restrictions, natural brightness is also by certain
Limitation；Simultaneously also in that being that light source is located in side, so and will lead to and the phenomenon that black surround area occur.There are also be exactly group
When filling light guide plate or LED, the tolerance of assembling directly affects luminous effect, to influence the yield of production product.
Utility model content
The purpose of this utility model is to be to solve the dependence to light guide plate, the limitation to LED quantity in existing product
Property, brightness not enough, when having black surround area and assembling the problems such as the yield of product, and a kind of LED is provided and shields liquid crystal display mode comprehensively
Group.
A kind of LED shields liquid crystal display die set comprehensively, and the liquid crystal display die set includes light guide plate and light source, described
Light source be two pieces or more LED area light source and close composition.
Further, the LED area light source is concatenated MINI LED.
Further, the LED area light source is MINI LED in parallel.
Further, the LED area light source is the MINI LED being collocated with each other in series and parallel together.
Further, the LED area light source is arranged in a matrix.
A kind of LED shields liquid crystal display die set comprehensively, and the liquid crystal display die set includes diffusion sheet and light source, described
Light source be two pieces or more LED area light source and close composition.
Further, the LED area light source is concatenated MINI LED.
Further, the LED area light source is MINI LED in parallel.
Further, the LED area light source is the MINI LED being collocated with each other in series and parallel together.
Further, the LED area light source is arranged in a matrix.
Beneficial effect by adopting the above technical scheme is：By zonal control area source, so as to improve to light guide plate
Dependence, the yield etc. when solving the uneven of backlight illumination, insufficient light and black surround area and improving assembling product.With reality
The regional dynamics control of existing liquid crystal, promotes the brightness of the HDR& display screen of display screen, and promote contrast.Revolutionary thinning
The thickness of screen liquid crystal touch control display module comprehensively.
Detailed description of the invention
Fig. 1 is structural schematic diagram described in the utility model；
Fig. 2 is structural side view one described in the utility model；
Fig. 3 is structural side view two described in the utility model.
In attached drawing, parts list represented by the reference numerals are as follows：
1-LED area source, 2- light guide plate, 3-FPC plate, 4- diffusion sheet.
Specific embodiment
The content of the utility model is made further below in conjunction with attached drawing and the utility model preferred specific embodiment
Explanation.Example is served only for explaining the utility model, is not intended to limit the scope of the utility model.
As shown in Figures 1 and 2, a kind of LED described in this programme shields liquid crystal display die set, the liquid crystal comprehensively
Display module includes light guide plate 2 and light source, and the LED area light source 1 that the light source is two pieces or more simultaneously closes composition；In this programme
The LED area light source 1 is either concatenated MINI LED, is also possible to MINI LED in parallel, can also be series-parallel
It is collocated with each other MINI LED together；In the present solution, the LED area light source 1 is arranged in a matrix, naturally it is also possible to be with
Other forms arrangement.
As shown in Figure 1 and Figure 3, a kind of LED described in this programme shields liquid crystal display die set, the liquid crystal comprehensively
Display module includes diffusion sheet 4 and light source, and the LED area light source 1 that the light source is two pieces or more simultaneously closes composition；In this programme
The LED area light source 1 is either concatenated MINI LED, is also possible to MINI LED in parallel, can also be series-parallel
It is collocated with each other MINI LED together；In the present solution, the LED area light source 1 is arranged in a matrix, naturally it is also possible to be with
Other forms arrangement.
When it is implemented, the LED area light source 1 is set on FPC plate 3, the quantity of LED area light source 1 can be in conjunction with specific
The structure of product is adjusted flexibly, and can be divided corresponding LED area light source according to the structure or design requirement of specific product
For different area arrangements, by controlling the light source in each region, so as to reach the face the LED light freely controlled in each region
Whether the brightness in source 1 and switch.For example only needing the LED area light source 1 in a certain region merely is to light, and other areas
The LED area light source 1 in domain is to be in close state.To from the dependence being addressed on source in existing product to light guide plate 2,
To the restricted, brightness of LED quantity not enough, when having black surround area and assembling the problems such as the yield of product.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
