CN203455816U - Vertical crossed wiring structure for TX and RX in Sennsor region of capacitive screen - Google Patents

Abstract

The utility model relates to a vertical crossed wiring structure for TX and RX in a Sennsor region of a capacitive screen, and belongs to the technical field of electronic equipment screens. A TX circuit is integrally distributed at one end of the capacitive screen; the TX circuit and an RX circuit are wired orthogonally on TPsensor. The vertical crossed wiring structure has the advantages that 1, the number of ACF prepressed segments are reduced, and the yield is increased; 2, the manufacturing segments of a binding tool bit are reduced from three segments to two segments and even one segment, machine debugging is easier, and the capacity and yield are increased; 3, the RX and the TX are wired in a centralized way, the FPC (Flexible Printed Circuit) wiring space can be reduced to a certain degree, and the FPC area is reduced.

Description

A kind of capacitance plate Sennsor region TX and RX square crossing Wiring structure

Technical field

The utility model relates to a kind of capacitance plate Sennsor region TX and RX square crossing Wiring structure, belongs to electronic equipment screen technical field.

Background technology

The thickness of capacitance plate pursuit is at present more and more thinner, introduced two-sided ITO material thereupon, the two-sided ITO of gold-tinted process using, can reduce one deck ITO film and one deck OCA, in manufacturing process, two-sided ITO layout is on traditional smaller screen, FPC divides three sections to carry out pressing, three sections are pressed in the two-sided tune machine difficulty of simultaneously existing, and ACF precompressed is the factor such as several times, affects efficiency and yield.

A: single-layer PET ITO pros and cons technique, ITO is distributed in PET pros and cons, due to frame restriction, Sensor TX circuit need be distributed in the right and left, thereby causes FPC binding contact point to divide right and left, and Sensor RX circuit occupy TX central distribution, as Fig. 1, this design causes binding in process of production and is divided into three sections of two sides, and the pre-subsides of ACF can not once complete, and during binding, FPC will clamp the unfavorable production operation factors such as Sensor contraposition.

B: the two-layer PET technique of double-deck ITO: due to frame restriction, Sensor TX circuit need be distributed in the right and left, thereby cause FPC binding contact point to divide right and left, Sensor RX circuit occupy TX central distribution, as Fig. 1, this design binding is positioned at the same face, but also needs to be divided into three sections, some design can once complete ACF and paste in advance, and some needs will separate in advance pastes.

C:RX and TX divide out three sections of cablings, increase design difficulty, need to open a binding step more, cause thus the techniques such as many sealings, increase manufacture difficulty.

Summary of the invention

In order to overcome above-mentioned defect, the utility model object is to provide a kind of capacitance plate Sennsor region TX and RX square crossing Wiring structure.

Thereby in the situation that guaranteeing that not affecting TP thinks performance, by integration, adjust binding hop count, the hot pressing that makes to fit in advance once completes, and improves yield and efficiency.

In order to achieve the above object, the utility model adopts following technical scheme:

Capacitance plate Sennsor region TX and a RX square crossing Wiring structure, one end that TX circuit is incorporated into capacitance plate distributes, TX circuit and RX circuit quadrature cabling on TP sensor.

TX circuit two ends distribute and are incorporated into one end distribution, and RX and TX be quadrature cabling on TP sensor, meets like this RX and TX cross-over design Rule, does not affect TP performance.

The beneficial effects of the utility model:

1. the utility model has reduced ACF precompressed hop count, promotes production capacity;

2. the utility model has reduced binding cutter head making hop count, from three sections to two sections, and even one section, make tune machine simpler, promote production capacity and yield;

3. the utility model RX and TX concentrate cabling, can reduce FPC cabling space to a certain extent, reduce FPC area.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with 1 pair of structural representation of the present utility model of accompanying drawing:

Capacitance plate Sennsor region TX and a RX square crossing Wiring structure, one end that TX circuit 1 is incorporated into capacitance plate distributes, TX circuit 1 and RX circuit 2 quadrature cabling on TP sensor.

TX circuit two ends distribute and are incorporated into one end distribution, and RX and TX be quadrature cabling on TP sensor, meets like this RX and TX cross-over design Rule, does not affect TP performance.

Claims (1)

1. capacitance plate Sennsor region TX and a RX square crossing Wiring structure, is characterized in that: one end that TX circuit (1) is incorporated into capacitance plate distributes, TX circuit (1) and RX circuit (2) quadrature cabling on TP sensor.
