Abstract
The invention discloses a light emitting diode (LED) liquid crystal display component. The LED liquid crystal display component comprises a backlight panel, a liquid crystal screen with liquid crystal pins, an LED lamp, a printed circuit board (PCB) and an infrared receiving tube, wherein the backlight panel is arranged on the PCB; the liquid crystal screen is arranged on the backlight panel; the upper surface of the backlight panel is provided with a plurality of positioning ribs for fixing horizontal position of the liquid crystal screen; the positioning ribs are positioned at the outer edge of the liquid crystal screen; a plastic extension end is arranged on one side of the backlight panel and provided with a plurality of positioning holes with positive/negative indication marks; and both the bottoms of the LED lamp and the infrared receiving tube penetrate through the positioning holes and are fixed on the PCB. The LED liquid crystal display component has the advantages of saving an independent LED positioning column, along with high reliability and production efficiency and more uniform mounting and assembly of a product.
Description
Technical field
The present invention relates to the display module in a kind of instrument and meter, relate in particular to a kind of LED LCD assembly.
Background technology
At present, backlight and LED reference column on many electronic products (as electric energy meter) all separate, and each the LED lamp on the pcb board all has independently LED reference column, and infrared receiving tube also supports by the LED reference column.And backlight has just supported the height of liquid crystal display, and all around direction is not located, and the liquid crystal stitch on the liquid crystal display is directly to insert in the pad hole of pcb board, without any auxiliary assembling wording.
Along with continuing to increase of cost pressure and improving constantly of quality, though this traditional mounting structure has been popularized a lot of years, but still there are a lot of shortcomings: at first, independent LED reference column assembling on the pcb board is very loaded down with trivial details, before its assembling, need to increase the preprocessing link, want earlier the LED lamp to be assembled in above the LED reference column, the unified again stitch of shearing LED lamp bottom, control its height, the easy wrong plug direction of the both positive and negative polarity of LED lamp in addition, rework rate is very high, has caused the production efficiency step-down, and cost of labor uprises; Secondly, the independent LED reference column Material Cost on the pcb board is very high, and LED lamp of every increase will increase a reference column; Moreover liquid crystal display has lacked location all around, occurs the phenomenon of left-right and front-back skew after assembling is finished easily, and the liquid crystal stitch of liquid crystal display is too many, difficulty is quite big during pad hole on the disposable insertion pcb board, wants plug-in mounting repeatedly just can enter usually, and the inexperienced operator is then more difficult.
Summary of the invention
The object of the present invention is to provide a kind of production cost lower, install faster, can be to the liquid crystal display direction LED LCD assembly that can both position all around.
This LED LCD assembly provided by the invention, comprise backlight, the liquid crystal display of band liquid crystal stitch, the LED lamp, pcb board and infrared receiving tube, described backlight is installed on the pcb board, described liquid crystal display is installed on the backlight, on the upper surface of described backlight, be provided with some positioning bars that are used for fixing the liquid crystal display horizontal level, described positioning bar is positioned at the outer edge of liquid crystal display, side in described backlight is provided with a plastic cement external part, have the pilot hole of some band both positive and negative polarity cue marks on this plastic cement external part, the bottom of described LED lamp and infrared receiving tube is all passed pilot hole and is fixed on the pcb board.
Described positioning bar becomes the L type and is wrapped in outside each turning of liquid crystal display.
Also be provided with some liquid crystal pilot holes on described backlight, the bottom of described liquid crystal stitch is passed this liquid crystal pilot hole and is fixed on the pcb board.
Compared with prior art, the present invention has the following advantages:
One, directly the LED lamp is positioned installation by the pilot hole on the backlight, the preprocessing link of LED reference column and LED lamp and the utilization of a plurality of independently LED reference columns have promptly been saved, removed each required operation of preprocessing, Material Cost and operation cost have been reduced, because of having located the height and the cathode and anode directions of LED lamp, the phenomenon of doing over again that is caused by anti-inserted direction can not appear again again.
Two, by the positioning bar that stretches out on the backlight with liquid crystal display all around direction fix, the phenomenon of liquid crystal left-right and front-back skew has not just existed yet, and the design of liquid crystal pilot hole makes that efficient is high when the liquid crystal display plug-in mounting, almost can once just insert.
Three, located the height and the position of infrared receiving tube by the pilot hole on the backlight, the phenomenon that makes infrared receiving tube no longer include skew takes place.
In a word, good reliability of the present invention, the production efficiency height has not only saved the independently utilization of LED reference column, also makes the installation assembling of product more unified.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that Fig. 1 A is to structural representation.
Embodiment
Can find out from Fig. 1 and Fig. 2, this LED LCD assembly of the present invention, comprise backlight 1, the liquid crystal display 2 of band liquid crystal stitch 21, LED lamp 3, pcb board 4 and infrared receiving tube 5, backlight 1 is installed on the pcb board 4, on the upper surface of backlight 1, be provided with the positioning bar 11 of 4 L types, the outside at four turnings of liquid crystal display 2 directly contacts and is horizontally fixed on the backlight 1 with the inboard of positioning bar 11, side in backlight 1 is provided with a plastic cement external part 12, have the pilot hole 13 of some band both positive and negative polarity cue marks on this plastic cement external part 12, the bottom of LED lamp 3 and infrared receiving tube 5 is welded on the pcb board 4 corresponding pad holes after passing pilot hole 13.With liquid crystal stitch 21 corresponding backlight 1 on also be provided with some liquid crystal pilot holes 14, the bottom of liquid crystal stitch 21 is passed this liquid crystal pilot hole 14 and is fixed on the pcb board 4 corresponding pad holes.
Assembling use of the present invention is as follows:
One, backlight 1 is installed on the pcb board 4, and guarantees that each pilot hole 13 on the backlight 1, liquid crystal pilot hole 14 align with corresponding pad hole on the pcb board 4.
Two, liquid crystal stitch 21 is aimed at liquid crystal pilot hole special-purpose on the backlight 1 14 and vertical the insertion, make four turnings of liquid crystal display 2 can both block with backlight 1 on positioning bar 11 in, liquid crystal stitch 21 then can insert in the pad hole of pcb board 4, welding is fixing.
Three, determine the position of each both positive and negative polarity on the pilot hole 13, one of LED lamp 3 and infrared receiving tube 5 band stitch rectified true each pilot hole 13 that passes insert in the pad hole of pcb board 4 that welding is fixing.
