Embodiment 1

[0021] A method for routing touch wires, including the process of forming touch wires on the surface of the rear 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 The main line of the touch line in the non-sintering area and the branch line of the touch line in the sintering area; the light transmission distance required for sintering is provided between the branch lines of the touch line; the width of the main line of the touch line is the touch The sum of the widths of the branch lines of the control line; the main line of the touch line is connected with the branch lines of the touch line. Both the trunk line of the touch line and the branch lines of the touch line are metal lines. The main line of the touch line is connected to the branch line of the touch line through a connection hole that can reduce resistance, and the width of the branch line is 7-12 μm. Th...

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...
