Description
Technical field
The utility model relates to field of liquid crystal display, relates in particular to a kind of ultra-thin liquid crystal display die group.
Background technology
Along with the fast development of the electronic products such as mobile phone, computer, TV, people enjoy that these electronic products bring simultaneously easily, also the experience on the sense organs such as vision is more and more focused on, so more and more stricter to the requirement of the electronic product of this kind of liquid crystal, because extra-thin liquid crystal electron product weight is light, easy to carry, volume is little and space-saving, also more attractive in appearance in appearance, so this series products obtains the favor of people more.But due to the structural limitations of liquid crystal display module itself, itself can not be luminous, need could realize luminescence by other light source, and increase the thickness that light source just inherently increases liquid crystal display module, the circuit simultaneously connecting light source is intricate, and circuit arranges the unreasonable liquid crystal display module thickness that also will certainly make to be increased.Existing liquid crystal display module adopts the mode of dot matrix, on average be placed in backlight by light source, be connected in turn by circuit again, although the mode of dot matrix is comparatively even in luminescence, but owing to increasing light source in backlight, the thickness being equivalent to superpose one block of plate gets on, simultaneously because light source is more, cause circuit more loaded down with trivial details, complex structure.
Utility model content
The purpose of this utility model is, for the problems referred to above, provide a kind of frivolous, structure simple, and the ultra-thin liquid crystal display die group that light utilization efficiency is high.
For achieving the above object, the utility model adopts following technical scheme:
A kind of ultra-thin liquid crystal display die group, comprise backlight module and the liquid crystal module of superposition setting, described backlight module and described liquid crystal module are fixed together by metal frame, wherein, described backlight module comprises light guide plate and LED lamp bar, described LED lamp bar is placed on the both sides up and down of described light guide plate respectively, the outlet port of described LED lamp bar is arranged on four angles place of backboard, the data line connecting described LED lamp bar is fixed on described backboard by sticking double faced adhesive tape, and the front of described light guide plate also superposes successively from top to bottom and is provided with bright enhancement film and diffusion barrier.
Further, described backlight module also comprises backboard, and described backboard is positioned at the bottom surface of described light guide plate, and the bottom surface of described backboard has also been screwed flexible printed circuit board.
Further, described flexible printed circuit board is electrically connected with LED lamp bar and IC main control module respectively.
Further, described liquid crystal module comprises the liquid crystal layer and glass substrate that superpose setting up and down, and the front of described liquid crystal layer superposes successively from top to bottom and is provided with one deck colored filter and two-layer polaroid.
Further, described glass substrate is TFT glass plate.
Further, described LED lamp bar comprises LED and carries the aluminium base of described LED.
Further, described metal frame is fixed together by the form of buckle and described backboard, and the described metal frame surrounding corresponding with described backboard is provided with the through hole passed for connecting line.
Implement the utility model and there is following beneficial effect: by LED lamp bar being arranged on the upper and lower both sides of light guide plate instead of bottom surface, therefore the increase of integral thickness is not caused, the adjustment of this layout greatly reduces the use of LED, thus reduce production cost and power consumption, be fixed on aluminium base after the single connection of LED, again by data line connecting overall, therefore structurally more simple, decrease the quantity of data line, data line passes rear use sticking double faced adhesive tape in the bottom surface of backboard from the angle of backboard, data line length can be reduced, also more fit simultaneously and between backboard, make on thickness thinner, in addition aluminium substrate is as the loading plate of LED, radiating effect is better, the rate of decay of the LED that can slow down luminescence, increase the service life.
