CN102182957A - Production method of LED (Light Emitting Diode) backlight sources - Google Patents

Abstract

The invention discloses a production method of LED (Light Emitting Diode) backlight sources, which comprises the following steps of: a, designing the shape, the specification and the light emitting point of single backlight source by using a computer; b, computer arrangement: determining arrangement position and number of single backlight source on the whole light guide plate according to the specification and the size of the whole light guide plate used for producing the backlight sources, and copying and arranging the single backlight source with designed shape, specification and light emitting point; c, film production of the whole plate: performing the film production of the whole plate after the arrangement; d, producing the whole plate into a screen printing plate; e, printing the whole plate; and f, laser cutting: cutting the whole printed light guide plate into respective backlight source products through laser. Therefore, a plurality of backlight source products with uniform quality can be produced simultaneously at one working cycle, the production efficiency is increased by more than 8 times, and the yield of the backlight sources produced by a person per day can reach more than 30000 LED; and moreover, the consumption of materials and energy sources is reduced, the labor force is saved, and the production cost is reduced.

Description

LED-backlit source production method

Technical field

The present invention relates to a kind of LED-backlit source production method.

Background technology

At present, some adopts the production method of die sinking injection moulding to produce the LED-backlit source, and working cycles of the method is produced 2-4 product, production cost height usually; Some adopts the production method of earlier single cutting back silk-screen scattering points, its sequence of steps is: laser cutting, design scattering points, the making of the single film, single system half tone, single printing, the method is single manual silk-screen, produce one by one, production efficiency is low, the loss of the material and the energy is big, production cost height, and quality inequality.

The utility model content

The technical problem to be solved in the present invention provides a kind of production method of LED-backlit source of energy high efficiency production quality homogeneous.

In order to solve the problems of the technologies described above, the method applied in the present invention may further comprise the steps order:

A. use shape, specification and the scattering points of the single backlight of computer design;

B. use desk-top publishing: the specification size that is used to make the LGP of backlight according to monoblock is determined the arrangement position and the quantity of single backlight on every monoblock LGP, and the single backlight that shape, specification and scattering points are designed duplicates and arranges;

C. the justifying film is made: the back justifying film of setting type is made;

D. justifying system half tone

E. justifying printing

F. laser cutting: the monoblock LGP that prints through justifying is carried out laser cutting, cut out each single backlight product.

Adopt method of the present invention, owing to adjusted the order of production stage, cutting step by the changing into after the justifying printing of prior art, is carried out laser cutting again after justifying is completed for printing before printing, cut out each single backlight product; Simultaneously, increased the step of desk-top publishing, and the making of the justifying film, justifying system half tone, justifying printing, like this, a working cycles can be produced the backlight product of a plurality of quality homogeneous simultaneously, enhances productivity more than 8 times, and output can reach more than 30000 for each person every day; Simultaneously, reduce the loss of the material and the energy, saved the labour, reduced production cost.

The specific embodiment

The method applied in the present invention may further comprise the steps order:

A. use shape, specification and the scattering points of the single backlight of computer design;

B. use desk-top publishing: the specification size that is used to make the LGP of backlight according to monoblock is determined the arrangement position and the quantity of single backlight on every monoblock LGP, and the single backlight that shape, specification and scattering points are designed duplicates and arranges;

C. the justifying film is made: the back justifying film of setting type is made;

D. justifying system half tone

E. justifying printing

F. laser cutting: the monoblock LGP that prints through justifying is carried out laser cutting, cut out each single backlight product.
