Description
Technical field
The present invention relates to the method for screen printing technology field more particularly to a kind of screen painting label, display panel, show
Showing device.
Background technique
The electronic products such as mobile phone, laptop currently on the market have using touch screen (Touch Panel), are touching
It touches in the manufacturing process of screen, it will usually the mark for printing off lightproof area by way of screen painting on the touchscreen, representing company
Know the label such as (Logo).
The prior art selects the reason of screen painting mode are as follows: half-tone screen printing method is flexible, cheap, print speed printing speed
Fastly；In the case where required precision is not high, it can replace by way of a variety of different labels of screen painting and pass through mask plate
(mask) mode for forming a variety of different labels, since the cost of halftone is far below the cost of mask plate, so that product is opened
Hair cost substantially reduces.
The prior art generally selects larger-size big screen painting standard shows panel (Q- in touch screen industry
Panel), the length of big halftone is generally 1.5 meters (m), and width is also generally 1.5m, and in printing process, one-step print can be with
Multiple single display panels (Panel) are printed out, the pitch time (tact time) of production is shorter, high-efficient；However it prints
The printing precision of the big halftone used when brush is poor, and the client high for required precision is unable to satisfy requirement.
Another mode of printing that the prior art generallys use is that the selection lesser small halftone of size carries out single Panel
Printing, the length of small halftone are generally 500 millimeters (mm), and width is generally also 500mm, although what the prior art used when printing
The printing precision of small halftone is higher, but the speed printed when the small screen painting of use is slower, tact time longer, low efficiency.
When the prior art makes alignment mark (mark) that precision is higher, color is silver color on the touchscreen, it can adopt
Contraposition mark is made with mask plate, although the contraposition mark for making formation is able to satisfy the requirement of precision, but when contraposition mark's
When position changes, need to modify mask plate accordingly, and the higher cost of mask plate, when leading to production contraposition mark at
This is higher.
In addition, though the contraposition mark for making formation can also expire when making contraposition mark by the way of small screen painting
The requirement of sufficient precision, but the prior art producing line design due to, using when small screen painting can only process black oil
Ink is unable to satisfy the requirement of contraposition mark color.
Summary of the invention

All other embodiment, shall fall within the protection scope of the present invention.
The method of the screen painting label of specific embodiment of the invention offer is provided with reference to the accompanying drawing.
As shown in Figure 1, the specific embodiment of the invention provides a kind of method of screen painting label, this method comprises:
S101, it needs to print on substrate using the first halftone at the position of the label, prints out with the first ink
One label；
S102, using the second halftone at position corresponding with first label, print out the second mark with the second ink
Note, so that the pattern after second label and first label are overlapped is identical as the pattern of the label；Wherein:
The printing precision of first halftone is less than the printing precision of second halftone；
The color of first ink is identical as the color of the label, the color of second ink and first mark
Remember that the back end color of the corresponding substrate at position is identical.
Preferably, in the specific embodiment of the invention the first halftone printing precision be 300 microns (μm) to 500 μm, second
The printing precision of halftone is 30 μm to 80 μm；Using the method most end form for the screen painting label that the specific embodiment of the invention provides
At the precision of label be 30 μm to 80 μm, the production precision of label is high.
When it is implemented, the specific embodiment of the invention makes the alignment mark that the label to be formed can be substrate, the present invention
Specific embodiment by substrate make the higher silver color alignment mark of precision for, in conjunction with attached drawing be discussed in detail production precision compared with
The detailed process of high silver color alignment mark.
As shown in Fig. 2 (a), in the specific embodiment of the invention size of substrate with the prior art make display panel when
For the size of glass substrate substrate is identical, firstly, substrate 20 is cut the position of dotted line along figure, substrate 20 is cut
Multiple first submount 201 are formed, the size of the first submount and the size of Q-Panel are identical.
As shown in Fig. 2 (b), then, printing contraposition is needed on every one first submount 201 respectively using the first halftone 21
At the position of label, is marked with the first ink 22 printing first, illustrated only in Fig. 2 (b) to one of them the first submount 201
The case where being printed.When it is implemented, the length of the first halftone 21 in the specific embodiment of the invention is 1.5m, width is
