Backlight module introduction
The backlight module is one of the key zero components of the LCD panel. The function is to supply sufficient brightness and distribution of light sources to make it possible to display images.
The main composition is: Light source (Lightguide), a lightguide, reflector, diffractor, a diffusing sheet (BEF, prism), black and white glue (CURTAIN TAPE) Wait. Since the backlight requirement is getting thinner, there is a portion of the metal frame to be added.
The LCD panel is mainly: consisting of a color filter, a backlight module, a drive IC, a compensation film, a polarizing plate, a glass substrate, an ITO film, an alignment film, a control circuit, and other zero components, since the liquid crystal panel itself does not light emitting characteristics, must The displayed function is achieved by means of a backlight module.

What issues should be paid attention to when the backlight mode should be paid:
Traditional backlight die cutting and other die cuts, backlighting is paying attention to specific materials, specific die-cutting processes, such as light-aluminum films should pay attention to the angle of lighting film, this is to adjust the mold cut direction , The direction of the knife mode, the backlight die cutting is the main leading and manufacturing environment of the production and manufacturing environment, the mold cutting process occupies the first key, the process of improving the qualification rate of the product.
How is the precision of the backlight die cut:
At present, the domestic die-cutting machine is inheritively mechanism. The precision between the matching and manufacturing of the link between the main rotation system directly affects the speed and jump distance of the die cutter, and the other is to make the mold in the mold. The development and production of knife molds are based, and it is deeply understood that the customer's product demand information is based on quite understanding of materials. The information to be expressed is presented on that design, so you have to review the first, convert the customer's requirements into your own process, and present the final product.
The key to the backlight mold cutting waste is:
Backlight mold cut, such as the bright box, the inner frame is made into a full-time, then look at the material, no matter what brand of black and white glue, there will be squeezed slope when you die, that is, when the knife is carried with the cotton When the whole force is pressed, the pressure will cause the two black and white glue compression, and at this time, the knife die is cut off, and we can see after the pressure disappears, and the edge incision is sloppy. The key to the discharge is at the angle, the tension of the machine, the backlight mold cutting waste first excludes the lamination of the inner frame, and then removes the bids, once, and the process is perfect.
Based on the above analysis, what kind of knife model do you think is better? In order to minimize the degree of extrusion, of course, the die cutter is selected, and if the amount is used to use aluminum blade.
Summary: Analysis on backlight mode cutting technology is shared with you.
