Example Embodiment

[0020] Example 1

[0021] A method for routing touch wires includes a process of forming touch wires on the surface of the back cover glass by MASK exposure and development. The glass surface is divided into a sintered area and a non-sintered area. The touch wires are divided into The touch line trunk line in the non-sintering area and the touch line branch line in the sintering zone; the distance between the touch line branch lines is set to transmit light required for sintering; the width of the touch line trunk line is The sum of the width of the control line branch line; the touch line trunk line is connected with the touch line branch line. The touch wire trunk and the touch wire branch wires are both metal wires. The main line of the touch line and the branch line of the touch line are connected through a connecting hole that can reduce resistance, and the width of the branch line is 7-12 μm. The surface of the back cover glass refers to the outer surface of the back cove...

[0025] A wiring method for touch wires includes a process of forming touch wires on the surface of the back cover glass through MASK exposure and development. The glass surface is divided into a sintered area and a non-sintered area, and the touch wires are divided into sintered areas. Touch wires in the non-sintered area; the touch wires in the non-sintered area are metal wires, the touch wires in the sintered area are transparent conductive wires, and the metal wires and the transparent conductive wires pass Connection hole connection. The width of the transparent conductive line is greater than the width of the metal line. The transparent conductive thread is any one of ITO conductive thread, Metal Mesh, Ag NW, Graphene conductive thread. The width of the transparent conductive line in the sintering zone is 100-200 μm. The surface of the rear cover glass refers to the front surface of the rear cover glass or the rear surface of the rear cover glass.

Abstract

The invention relates to the technical field of touch screen OLED packaging, in particular to a touch line routing method for a touch SENSOR. The method comprises a process of forming a touch line onthe glass surface of a back cover through MASK exposure development; the glass surface is divided into a sintering region and a non-sintering region; the touch line is divided into a main touch line in the non-sintering region and branch touch lines in the sintering region; a light-transmitting distance required for sintering is arranged between the branch touch lines; the width of the main touchline is the sum of the widths of the branch touch lines; and the main touch line is connected with the branch touch lines. The touch routing comprises line arrangement of the sintering region and thenon-sintering region; the bezel of a screen is reduced as far as possible; the usage range of the screen is expanded; and normal routing and high sintering quality can be ensured.

Description

technical field [0001] The invention relates to the technical field of touch screen OLED packaging, in particular to a touch sensor wiring method. Background technique [0002] With the development of digital products, mobile phone products are becoming thinner and thinner, and more and more touch functions are integrated on the display screen, so there are more and more ON-CELL / IN-CELL products; ON-CELL / IN -The sensor design of CELL products is different from the sensor design of previous touch products, and the overall cooperation with LTPS needs to be considered. At present, most mobile phones require a narrow frame design, so it is impossible for the SENSOR staff to completely avoid the sintering area. Some wiring must be in the sintering area. However, the wiring of SENSOR's touch wires in the sintering area often results in poor packaging quality of the upper and lower glass of the entire screen. [0003] The ON-CELL routing design in the sintering area is very impor...
