The manufacturing method provided by the invention has the advantages that part of procedures for the backlight are carried out in the LCD procedures, so as to save man-hours; meanwhile, due to an excellent LCD manufacturing environment, the product quality and the yield are improved.
Description
Technical field
The present invention relates to liquid crystal module manufacturing technology, particularly the method for making that combines of liquid crystal module and backlight source module.
Background technology
In prior art, liquid crystal module and backlight source module are all separately produce,------dress LED---the operations such as visual examination that pad pasting---adds electrical testing---that film is cut that backlight needs through forming light guide plate in process of production, when wherein light guide plate and diffusion barrier, brightness enhancement film combine, production environment and operation gimmick are required extremely tight, control with great difficulty not occur that backlight stain and other foreign substance pollution etc. are bad; And backlight and liquid crystal display combine, also to carry out the welding of LED electrical pole, often occur the problem of rosin joint or solder skip, have influence on the quality of product.In addition, the technics comparing produced due to backlight is simple, cost drops into little, a lot of medium and small sized enterprises all at this product of production, due to the restriction of the conditions such as scope of the enterprise, not fine for environmental Kuznets Curves in backlight assembling process, had influence on the quality of backlight.
Summary of the invention
The invention provides the method for making that a kind of backlight and liquid crystal display combine module, critical process is adopted to complete by LCD operation, improve yields, simplify backlight production process simultaneously, solve backlight quality in prior art and the not good technical matters of assembling quality.
The present invention solves the problems of the technologies described above this backlight that proposes and liquid crystal display to combine module method for making and comprise: the diffusion barrier that backlight uses by liquid crystal display in manufacturing process and the lower polaroid that liquid crystal display uses first are complex as a whole, when there being brightness enhancement film, the lower polaroid that the diffusion barrier that backlight uses uses with liquid crystal display together with brightness enhancement film is complex as a whole, then be attached on liquid crystal display, the backlight semi-manufacture and liquid crystal display contraposition that do not post diffusion barrier and brightness enhancement film fitted into one.The backlight semi-manufacture (i.e. light guide plate) not posting diffusion barrier and brightness enhancement film are fitted into one with liquid crystal display contraposition.
The method of described diffusion barrier, brightness enhancement film and lower polaroid compound comprises: diffusion barrier, brightness enhancement film and whole of lower polaroid are complex as a whole; then by product size requirement cutting; and the method that described backlight semi-manufacture (i.e. light guide plate) and liquid crystal display contraposition are fitted comprises: the diaphragm of composite membrane on first tear respectively diaphragm on backlight binding face and liquid crystal display; the dirt of clean liquid crystal display and light guide plate coating surface, fits backlight semi-manufacture (i.e. light guide plate) and liquid crystal display contraposition.
In method for making of the present invention further in the COG binding procedure of liquid crystal display, the LED that backlight uses directly is produced on the FPC of liquid crystal display, when liquid crystal display and backlight semi-manufacture are assembled, LED part on FPC is arranged on the assigned address of backlight source light conducting plate.
The present invention arranges protruding chimb at the periphery of described light guide plate further, and the diffusion barrier of backlight is attached to the upper surface of this chimb, carries out powering up test completing after backlight semi-manufacture (i.e. light guide plate) and liquid crystal display contraposition are fitted in method for making of the present invention.
Backlight unit operation break-down is put in liquid crystal display operation and makes by the present invention's employing, saves man-hour, meanwhile, because liquid crystal display production environment is very excellent, also improves the quality of product, improves yields.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that diffusion barrier in the present invention, brightness enhancement film and polaroid synthesize.Fig. 2 is the structural representation of light guide plate of the present invention with chimb.
Embodiment
In conjunction with above-mentioned accompanying drawing, specific embodiments of the invention are described.
From in Fig. 1, the method for making that backlight of the present invention and liquid crystal display combine module comprises: the lower polaroid 4 that the diffusion barrier 1 that backlight uses by liquid crystal display in manufacturing process, brightness enhancement film 2 use with liquid crystal display 3 is complex as a whole, and be attached on liquid crystal display, and will backlight semi-manufacture 5(and the light guide plate of diffusion barrier do not posted) fit into one with liquid crystal display contraposition.The subsides diffusion barrier of backlight, brightness enhancement film operation are put in the production process of liquid crystal display by the present invention, utilize the excellent condition of liquid crystal display production environment, ensure the quality of pad pasting, simultaneously, the operation of this part is saved in backlight production process, time saving and energy saving, also ensure that quality.
From in Fig. 1, for enhancing productivity further, the method of diffusion barrier of the present invention, brightness enhancement film and lower polaroid compound comprises: diffusion barrier, brightness enhancement film and whole of lower polaroid are complex as a whole, then by product size requirement cutting, overall compound is adopted in the present invention, then the mode of cutting, also can save the man-hour of twice cutting, raise the efficiency.The method that backlight semi-manufacture (i.e. light guide plate) of the present invention and liquid crystal display contraposition are fitted comprises: the diaphragm of first tear respectively diaphragm on backlight binding face and liquid crystal display; the dirt of clean liquid crystal display and light guide plate coating surface, fits backlight semi-manufacture (i.e. light guide plate) and liquid crystal display contraposition.Clean and the cleaning process in assembling procedure in production run puts together by this operation, saves time, and, assemble after clean at once, also ensure that cleanliness, reduce waste product.
From in Fig. 1, this method for making is in the COG binding procedure of liquid crystal display, the LED 6 that backlight uses directly is produced on the FPC7 of liquid crystal display, when liquid crystal display and backlight semi-manufacture (i.e. light guide plate) are assembled, LED part on FPC is arranged on the assigned address of backlight source light conducting plate.Also need, by the electrode welding of LED on FPC, easily to occur solder skip and rosin joint in traditional backlight source and liquid crystal display assembling process, the LED needed for backlight is directly directly produced on FPC by the present invention, save the operation of welding, save man-hour, meanwhile, also avoid welding to go wrong.
From in Fig. 2, the present invention arranges protruding chimb 51 at the periphery of described light guide plate, and the diffusion barrier of backlight is attached to the upper surface of this chimb, makes diffusion barrier and light guide plate leave certain gap, and preferred gap width is 0.2mm.The effect leaving gap is: if light guide plate surface has minute protrusions or particle, this gap ensures after being assembled into liquid crystal module, even if liquid crystal display is squeezed, lighting backlight also there will not be backlight speck, stain etc. bad, reduce in liquid crystal module application process, the bad order phenomenon of the stressed rear easy appearance of screen.Carry out powering up test completing after backlight semi-manufacture (i.e. light guide plate) and liquid crystal display contraposition are fitted in this method for making.
