Abstract
The utility model discloses a touch screen with a filling hole structure. The touch screen comprises a screen body and a flexible circuit board. An electricity conducting circuit layer is distributed on the screen body. A filling hole is formed in the flexible circuit board. Crossed walking wires on the same face in the electricity conducting circuit layer penetrate through the filling hole and are connected. The screen body is a touch screen body on a cell phone or a laptop computer or a personal digital assistant (PDA) or a digital camera. The filling hole is formed in the flexible circuit board, the filling hole in one glass solution (OGS) technology is changed to be formed in the flexible circuit board, and accordingly die-open time is shortened, and cost is greatly lowered.
Description
Technical field
The utility model relates to a kind of touch-screen, relates in particular to a kind of touch-screen with grout structure.
Background technology
The projected capacitive touch panel major technique that is applied as demand with the multipoint mode touch-control is divided into two kinds of diaphragm type (film type) and glass types (glass type), the apple camp adopts glass projecting type capacitor (glass type), but not the apple camp is then take film projecting type capacitor (film type PET) as main; At present the diaphragm type structure of main flow is by photoetching or be printed on the PET film with ITO; skin is called GFF (Glass-Film-Film) structure for cover glass; and the glass type structure of main flow system is made in touch sensing on the ito glass, and skin adds that a slice cover glass is to be GG (Glass-Glass) structure.The former is subject to high-order ito thin film material and rests in the minority Japanese trader hand, and latter GG binding yield is generally on the low side, all causes the high main cause of projected capacitive touch-control module cost.
In order effectively to reduce the touch-control module cost, satisfy simultaneously the lightening market trend of terminal consumption electronic product, nearly 2 years touch-control dealers actively set about research and development and reduce ito thin film or ito glass consumption, layout development OGS, embedded touch or GF thin film technique.OGS (One glass solution) structure: the technology that on cover glass, directly forms ITO conducting film and sensor.The OGS technology is with ito glass and the integrated sheet glass of cover glass; a glass plays the double action of cover glass and touch sensor simultaneously; not only can reduce by a sheet glass; also save the processing procedure of fitting together; than 0.4 millimeter thickness of two-piece type G/G product attenuate, estimation can be saved about 5 one-tenth costs approximately.
General single sided board processing procedure comprises following flow process: open material → printing MK etching → demoulding → LENS1 printing curing → SG printing curing → PS printing curing → LENS2 printing curing → LENS3 printing curing → crimping FPC → electrical measurement → inspection at end.Wherein, at contact panel, particularly the perforate die sinking time on the GLASS panel long, yield is low, is a technique difficult problem always.
The utility model content
Technical problem to be solved in the utility model provides a kind of touch-screen with grout structure, can reduce the die sinking time, greatly reduces cost.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of touch-screen with grout structure, comprise screen body and flexible PCB, be distributed with the conducting wire layer on the described screen body, wherein, offer grout on the described flexible PCB, the cross wiring that is positioned at the same face in the layer of described conducting wire passes grout and links to each other.
The above-mentioned touch-screen with grout structure, wherein, described screen body is the touch-screen on mobile phone, notebook computer, PDA or the digital camera.
The above-mentioned touch-screen with grout structure, wherein, described screen body material is PET plastics or glass baseplate.
The utility model contrast prior art has following beneficial effect: the touch-screen with grout structure that the utility model provides, by offering grout at flexible PCB, grout in the OGS technique is changed to walk on flexible PCB, thereby reduce the die sinking time, greatly reduce cost.
Description of drawings
Fig. 1 is the touch screen structure synoptic diagram that the utlity model has the grout structure.
Among the figure:
1 screen body, 2 flexible PCBs, 3 grouts
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the touch screen structure synoptic diagram that the utlity model has the grout structure.
See also Fig. 1, the touch-screen with grout structure that the utility model provides comprises screen body 1 and flexible PCB 2, be distributed with the conducting wire layer on the described screen body 1, wherein, offer grout 3 on the described flexible PCB 2, the cross wiring that is positioned at the same face in the layer of described conducting wire passes grout 3 and links to each other.
The touch-screen with grout structure that the utility model provides, be originally that the via hole that will pass through at the cross wiring of the same face on the screen body 1 is at different plane upward wirings, on being used in this grout mode on the flexible PCB 2 now, thereby reach saving cost, operation.Flexible PCB is that make take polyimide or mylar as base material a kind of has height reliability, and excellent flexible printed circuit is called for short soft board or FPC, has that distribution density is high, lightweight, the characteristics of thin thickness.
The touch-screen with grout structure that the utility model provides, wherein, described screen body 1 is the touch-screen on the products such as mobile phone, notebook computer, PDA, digital camera or LCM.Described screen body 1 material is PET plastics or glass baseplate.
In sum, the touch-screen with grout structure that the utility model provides is by offering grout 3 at flexible PCB 2, grout in the OGS technique is changed to walk on flexible PCB, avoid at contact panel, particularly perforate on the face glass, thereby reduce the die sinking time, greatly reduce cost.
Although the utility model discloses as above with preferred embodiment; so it is not to limit the utility model; any those skilled in the art; within not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
Claims (3)
1. touch-screen with grout structure, comprise screen body (1) and flexible PCB (2), be distributed with the conducting wire layer on the described screen body (1), it is characterized in that, offer grout (3) on the described flexible PCB (2), the cross wiring that is positioned at the same face in the layer of described conducting wire passes grout (3) and links to each other.
2. the touch-screen with grout structure as claimed in claim 1 is characterized in that, described screen body (1) is the touch-screen on mobile phone, notebook computer, PDA or the digital camera.
