Problems solved by technology

[0004] However, the existing segmented printing method divides the actual printing area evenly on the basis of the single maximum effective stroke. If the FPC outlet position is not in the middle of the bottom, there will be a problem that the number of actual segments will increase, and the segmented printing There will inevitably be ink overlapping areas at the critical point

Embodiment 1

[0064] The method for oversized splicing printing described in this embodiment includes the following steps:

[0065] (1) Calculate the number of segments according to the formula z=int(x / y)+1, divide the size to be printed equally according to the number of segments, and determine the critical point; among them, x is the actual size to be printed, and y is the maximum effective printing Size, z is the number of divisions; such as figure 1 As shown, if the number of divisions is 2, determine the critical point 11; the outlet position of the external FPC3 is not at the critical point of equal division;

[0066] (2) Ink is printed in each segmented printing area of ​​substrate 1, and the inks of adjacent segmented printing areas are respectively located on both sides of substrate 1, thereby avoiding the overlap of ink at the critical point of segmented printing area; the printing of ink The thickness can be adjusted according to actual needs, which can be 5-6μm;

Embodiment 2

[0071] The method for oversized splicing printing described in this embodiment includes the following steps:

[0072] (1) Calculate the number of segments according to the formula z=int(x / y)+1, divide the size to be printed equally according to the number of segments, and determine the critical point; among them, x is the actual size to be printed, and y is the maximum effective printing Size, z is the number of divisions; such as Figure 4 As shown, if the number of divisions is 4, determine the critical point 11; the outlet position of the external FPC3 is not at the critical point of equal division;

[0073] (2) Ink is printed in each segmented printing area of ​​substrate 1, and the inks of adjacent segmented printing areas are respectively located on both sides of substrate 1, thereby avoiding the overlap of ink at the critical point of segmented printing area; the printing of ink The thickness can be adjusted according to actual needs, which can be 5-6μm;

Abstract

The invention relates to the technical field of touch control display components, in particular to an oversize splicing printing method, a splicing printing structure and an application thereof. The method comprises the following steps: determining critical points of segmented printing areas of a substrate and printing ink in each segmented printing area of the substrate, where printing ink in adjacent segmented printing areas is on two sides of the substrate; building an FPC bridge between adjacent segmented printing areas in which interference tracing areas exist, with both ends of the FPC bridge being respectively bound to the ink of the adjacent segmented printing areas. Ink is printed in each segmented printing area, and the ink of adjacent segmented printing areas is respectively positioned on two sides of the substrate, so that ink overlap at the critical points of the segmented printing areas is avoided. The FPC is arranged between adjacent segmented printing areas with interference tracing areas to electrically connect the ink on both sides of the substrate; in the subsequent processing of products such as touch screens, FPCs externally connected with a control panel can be arranged according to subsequent actual needs.

Description

technical field [0001] The present invention relates to the technical field of touch display components, in particular to a super-large size splicing printing method, splicing printing structure and application. Background technique [0002] With the continuous development of smart display systems, terminal products under the new retail industry mode have emerged as the times require, and large-size touch all-in-one computers have become an indispensable part of human-computer interaction. The core of a large-size touch all-in-one machine is a large-size touch screen, and the large-size touch screen has advanced from a large-size infrared touch screen to a large-size capacitive touch screen. [0003] At present, the large-size capacitive touch screens that are mature in the market are relatively expensive. The effective range of the existing single-segment printing depends on the maximum effective stroke of the printing equipment. If the actual printing area is greater than...
