Description
Technical Field
The present disclosure relates to touch display screens, and particularly to a method for manufacturing a touch display module.
Background
The main stream touch screen has the advantages that the parts playing the role of touch are hidden under the first layer of cover plate, namely, the glass cover plate protective layer and the functional layer are two independent parts, and then the parts are bonded through optical glue to form TP, so that the most common product structure enables each touch screen manufacturer to produce different processing technologies, namely, one layer of glass cover plate plays the roles of protecting touch and attractive appearance, and a functional sheet processed by ITO glass or an ITO film is added, so that the structure of the product on the market at present is shown in figures 1, 2 and 3, and mainly has GF/GFF/GG (wherein cover lens is the cover plate, ITOglass or ITO flim is the functional sheet). The disadvantages of this are: the cover plate and the functional sheet need to be independently opened, the mold opening time is long, and the cost is high; the cover plate and the functional sheet processing plant are two independent processing units, so that the production time is longer, and the material turnover time is longer; the application field is limited, and the touch point is only used for consumer products below 10.1 inches, and only supports 5-point touch at the highest point, so that the touch experience is poor; with the requirements of consumers on touch experience, GF products based on single-point + gesture or single-layer two-point self-contained touch have failed to meet the requirements of wide consumers, phased out.
Compared with the plug-In Touch module gf\gff\gg technology, the main TFT or AMOLED panel factory is prone to develop an In Cell Touch technology, as shown In fig. 4 and 5, the sensor is directly manufactured In the display, and the two technologies of In-Cell and On-Cell can be roughly classified, so that the advantages of the In Cell Touch technology can be divided into two technologies, namely, one glass and one bonding process, but since the introduction of the In Cell technology panel factory must have LTPS technology, the entering threshold is relatively high, and the yield of the current process is low. In terms of cost, the purpose of making the in-cell is not to reduce cost and thickness, and if touch-on-lens can realize partial effect, the marginal effect brought by the in-cell is less obvious, and particularly obvious cost saving is not brought about in terms of cost.
In-cells have difficulty In ensuring yield and display performance because a touch sensor function needs to be embedded inside a pixel on a TFT array substrate. For this reason, a complicated semiconductor manufacturing process must be used, which becomes a tripolite for improving the yield. Further, the area available for display is reduced by embedding a touch sensor in a pixel, which is a factor of deterioration in image quality.
The touch scheme is limited, compared with a plug-In touch screen, the In-Cell/On-Cell touch IC has a smaller selection range, and the In-Cell/On-Cell screen needs to be embedded with a matched touch IC, otherwise, an error touch sensing signal or excessive noise is easily caused.
The ultrathin design causes the panel to be fragile, so that cover plate protection glass is indispensable, the cover plate layer is difficult to be omitted by the in-cell, and the in-cell is meaningless.
On-Cell is applied to three-star Amoled panel products, and the problem of uneven color generated during thinning and touch control cannot be overcome in the technology.
Disclosure of Invention
In view of the above existing technical problems, the present invention provides a method for manufacturing a touch display module, which combines a protective layer and a functional layer into a whole, has functions of protecting and receiving signals, and omits the links of independently opening a die and independently processing a cover plate and a functional sheet.
In order to solve the technical problems, the invention adopts the following technical scheme: a manufacturing method of a touch display module comprises the following steps:
A. coating film on the silk-screen surface of the cover plate, namely sputtering indium tin oxide onto the cover plate through a magnetron sputtering process to form a conductive surface;
B. manufacturing an RX conductive circuit layer on the conductive surface of the cover plate for sensing and receiving touch signals, forming the cover plate with the RX conductive circuit layer, and integrating the functional layer with the signal receiving function and the cover plate protection layer;
C. binding the flexible circuit board with the RX conductive circuit layer;
D. using ITO glass or an ITO film as a base material, and making a conductive surface of the TX conductive layer;
E. manufacturing a TX conductive circuit layer on the conductive surface of the TX conductive layer;
F. bonding the optical adhesive and the TX conductive layer, cutting the outline of the optical adhesive by using a cutting machine, and binding the flexible circuit board and the TX conductive layer;
G. and attaching the cover plate with the RX conductive circuit layer to the lower TX conductive circuit layer through an attaching machine to form the touch display module.
The manufacturing steps of the RX conductive circuit layer and the TX conductive circuit layer are printing, baking and photoetching in sequence; the printing flow is as follows: placing conductive ink on the screen printing plate with the patterns, and printing the ink on the conductive surface of the cover plate or the conductive surface of the TX conductive layer through a scraper; the baking process comprises the following steps: placing the cover plate or the TX conductive layer printed with the pattern into an oven or an IR tunnel oven for baking; the photoetching process comprises the following steps: and placing the baked cover plate or the TX conductive layer on a photoetching machine platform to etch the circuit, so as to form the circuit required by the touch screen.
In the invention, the RX conductive circuit layer and the TX conductive circuit layer are printed with conductive silver paste circuit layers.
The invention further provides the cover plate ink baking parameters: an IR tunnel furnace, wherein the baking temperature is 150 ℃ and the duration is 15-20min; the baking parameters of the conductive silver paste are as follows: oven, baking temperature 150 deg.C, and time period 60min.
In the invention, an insulating ink layer is arranged between the RX conductive layer or the TX conductive layer and the silver paste circuit layer, a via hole is reserved on the insulating ink side in advance, and conductive carbon paste is poured into the reserved hole, so that the conductive layer and the silver paste conductive layer are conducted, and a complete conductive circuit is formed.
In the invention, the bottoms of the RX conductive circuit layer and the TX conductive circuit layer are subjected to screen printing of the cover bottom of the ink.
The invention further provides a laminating machine in the step G, wherein the laminating machine adopts full-laminating AB glue for lamination.
In the invention, after the TX conductive layer is combined with the cover plate, the lower part of the TX conductive layer is combined with the liquid crystal module through the bonding layer to form the touch display module, and the bonding layer adopts full-bonding AB glue.
In the invention, the cover plate is made of glass, and before the step A, the glass raw material is sequentially subjected to the working procedures of cutting, CNC, engraving, tempering, screen printing and baking to form the cover plate frame.
The beneficial effects of adopting above-mentioned technical scheme are: the cover plate is taken as a part of the touch carrier and is combined with the conductive layer with the touch function to form the novel OGFtouch display module, namely ONE GLASS FILM, and the cover plate combines the protective layer and the functional layer into a whole and has the functions of protecting and receiving signals.
The OGFtouch display module has a large difference in structure from an incell/oncell module. In the case of the product directly exposed on the outermost surface, the surface layer is not protected, and the product is easily scratched, even the display effect is affected. The OGFs fully-attached products combine the glass protection layer and the functional layer into a whole, and then fully attach the glass protection layer and the liquid crystal, so that the scratch resistance of the touch module can be enhanced, the glass protection layer is used as a part of the functional component, and the glass protection layer can also play an explosion-proof role after being attached to the ITO flim layer.
The OGFtouch display module is integrated, the transmittance is enhanced, the air layer is removed by combining the OGFtouch display module with the full-lamination AB glue lamination technology, the influence of air refraction on unclear blurring and the like caused by display effect is reduced, the light reflectivity is low, the influence of a strong light environment on the display effect is small, the display effect is enhanced, the display is clearer, the picture is more vivid, the power consumption of the touch display module is reduced, the effects of light weight, thinness and electricity saving are achieved, and the duration of the whole machine is enhanced for handheld equipment.
The cover plate is an important part with the main protection and attractive functions in the touch screen, the cover plate is processed, the mutual capacitance type touch screen principle is used, the distributed RX conductive circuit layer responsible for receiving the induction touch signals is arranged on the screen printing surface of the cover plate in a film coating mode and the like, the links of independent die opening and independent processing of the cover plate and the functional sheet are omitted, the cost is reduced, the labor is reduced, the time is prolonged, the turnover is shortened, and the like, and meanwhile, the light and thin market trend of terminal electronic products is met.
And a TX conductive circuit layer used as a mutual capacitance type touch screen for transmitting a driving signal is attached to the upper layer surface of the self-contained RX conductive circuit, so that the OGFE type touch screen can realize multi-point touch, such as 5-point touch, 10-point touch, 20-point touch and 40-point touch.
The invention is not limited by the size of the product, and the product can be processed by using the process.
Because OGFtouch display module assembly adopts full laminating AB glue, the prototype is the glue that wide application used in cell-phone processing, through the mode to AB glue increase viscosity, adjusts the formula. After adjusting AB glue viscosity, when OGFs touch layer and liquid crystal laminating, there is not the risk of bounce after liquid organic silica gel bonding laminating, does not have the phenomenon of glue overflow, can reach the effect of easier laminating, saves processing procedure. In addition, because glue viscosity matches the back with the screen laminating, if when the bad condition of touch layer appears in the reproduction, reworking disassembles also very much, can directly tear, just like the cell-phone pastes the tempering membrane, after the tempering membrane is damaged, can directly tear the same effect of tempering membrane. Thus, if after-sales problems occur in the product when the product is used at the terminal, non-professionals can also directly replace parts and repair the parts.
