Description
Technical Field
The utility model relates to a LCD TV field especially relates to a straight following formula backlight unit bearing structure.
Background
The LCD TV comprises an LCD panel and a backlight module. Since the lcd panel does not emit light, the backlight module is one of the key components of the lcd device because the backlight module needs to provide a light source to normally display images. The Mini-LED backlight module takes a lamp panel consisting of a large number of small LED lamp beads as a backlight source, has the characteristics of high dynamic contrast, high brightness and ultrathin thickness, and is the development trend of the backlight technology of the liquid crystal display television in the future.
There is mixed light clearance in the straight following formula backlight unit of traditional LCD TV, need increase diffuser plate bearing structure in the bottom of being shaded in order to support the diffuser plate on upper portion, what generally adopt at present sets up some very little pillars at the interval on the LED lamp plate and supports the diffuser plate, has certain not enough at structural stability and installation convenience. In addition, the number of the lamp beads on the mini-LED lamp panel is large and dense, the lamp beads are not protected, and the mini-LED lamp panel is easy to be damaged by collision in the taking and assembling processes.
SUMMERY OF THE UTILITY MODEL
For overcoming the above-mentioned not enough that current backlight unit exists, the utility model discloses the technical problem that will solve is: the utility model provides a firm, the installation of being convenient for of structure can play the straight following formula backlight unit bearing structure of guard action to the lamp plate simultaneously.
The utility model provides a technical scheme that its technical problem adopted is:
straight following formula backlight unit bearing structure, including setting up the support column at four angles of LED lamp plate and middle part, the support column includes base and the stand that is located the base middle part, the base is the grid structure, LED lamp pearl on the LED lamp plate is located the net of base.
Further, the base is of a rectangular structure integrally, and the length and the width of the base respectively comprise at least two LED lamp beads.
Further, the grids of the base grid structure are circular or rectangular, and the upright posts are triangular or conical.
Further, the thickness of the base is 0.7-2mm, when the grid is circular, the diameter of the circular grid is 2-15mm, and when the grid is rectangular, the length and the width of the rectangular grid are 2-15 mm.
Furthermore, the support columns are made of transparent materials.
Furthermore, the support column is made of PC or PMMA.
The utility model has the advantages that: the base that adopts the grid structure can increase the area of contact of support column and LED lamp plate to improve the stability of base and the convenience of installation, have advantages such as subsides dress technology efficiency height and low cost, install the support column on four angles of LED lamp plate and middle part simultaneously, can play even supporting role to the diffuser plate of top, can play the guard action to the edge of LED lamp plate again.
Drawings
Fig. 1 is a front view of the structure of the present invention.
Fig. 2 is a top view of the present invention.
Fig. 3 is a schematic diagram of the overall arrangement of the present invention.
Marked in the figure as 1-LED lamp panel, 2-support column, 11-LED lamp bead, 21-base and 22-support column.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-3, the utility model discloses a straight following formula backlight unit bearing structure, including setting up support column 2 at four angles of LED lamp plate 1 and middle part, support column 2 includes base 21 and the stand 22 that is located base 21 middle part, base 21 is the grid structure, LED lamp pearl 11 on the LED lamp plate 1 is located base 21's net. Compare the pillar of current single-point formula, the base 21 of the grid structure that this application adopted can increase the area of contact of support column 2 and LED lamp plate 1 to improve the stability of base 21 and the convenience of installation, and LED lamp pearl 11 on the LED lamp plate 1 is located the light source effect that provides that backlight unit also does not influence in the net of base 21. Simultaneously, install base 21 on four angles of LED lamp plate 1 and middle part, can play certain guard action to the edge of LED lamp plate 1.
In order to facilitate installation and improve the protection effect on the periphery of the LED lamp panel 1, the base 21 is of a rectangular structure and is aligned with the corner of the LED lamp panel 1, at least two LED lamp beads 11 are required to be contained in the length direction and the width direction of the base, and the base can contain 4-64 LED lamps 11 according to a small liquid crystal screen generally adopting a Mini-LED backlight module.
The specific structure of the supporting column 2 can take various forms, the grid of the lattice structure can take a circular or rectangular shape, and the pillar 22 can take a triangular or conical shape.
Further, in order to reduce the influence of the substrate 21 on the LED lamp light source, the thickness of the base 21 is preferably 0.7-2mm, when the grid is circular, the diameter of the circular grid is preferably in the range of 2-15mm, and when the grid is rectangular, the length and width of the rectangular grid are preferably in the range of 2-15 mm.
As for the material, the support post 2 is preferably made of a transparent material, such as transparent PC or PMMA, which can further reduce the influence of the substrate 21 on the light source such as LED.
The utility model discloses an adopt the support column that has the base of jumbo size grid structure at four angles and the middle part of LED lamp plate to support the diffuser plate, increased the area of contact of support column with the LED lamp plate to improved the stability of support and the convenience of installation, had advantages such as dress process efficiency height and low cost, can play the guard action to the edge of LED lamp plate simultaneously, had fine practicality and application prospect.
