Description

Technical Field

[0001] The present invention relates to the technical field of touch screen production, and specifically to a method for solving the short circuit between the ITO channel and the floating block of the touch screen. Background Art

[0002] Based on the single-layer circuit and double-layer circuit of the touch screen design, since the touch screen with double-layer mutual capacitance design has more stable anti-interference and usability, the double-layer mutual capacitance design is mostly selected. Due to the anti-interference floating blocks in the ITO design of the mutual capacitance double layer, the manufacturing processes include laser ablation, exposure and development, and etching paste processes. During the production process, there will be a certain proportion of short circuits between the floating blocks and the ITO channels, resulting in functional defects with high single-point data.

[0003] Therefore, in order to correct the above defects, we propose a method for solving the short circuit between the ITO channel and the floating block of the touch screen. Summary of the Invention

[0004] The technical problem solved by the present invention is to propose a method for solving the short circuit between the ITO channel and the floating block of the touch screen.

[0005] To achieve the above object, the present invention provides the following technical solution: A method for solving the short circuit between the ITO channel and the floating block of the touch screen, adding a laser line between the ITO main channel and the floating block.

[0006] Further, the width of the laser line is 0.1 - 0.4 mm.

[0007] Further, the width of the laser line is 0.1 mm.

[0008] Compared with the prior art, the beneficial effect of the present invention is that: The present invention adds a laser line with a width of 0.1 mm between the ITO main channel and the floating block. The function of adding the laser line is that when the laser line at the edge of the channel is not ablated, the added laser line plays a secondary protection effect, avoiding the problem of high values caused by the short circuit between the floating block and the main channel.

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0014] The present invention provides a technical solution:

[0015] Please refer to Figures 1-4 , a method for solving the short circuit between the ITO channel and the floating block of the touch screen, adding a laser line with a width of 0.1-0.4 mm between the ITO main channel and the floating block.

[0016] In the industry, floating blocks with a spacing of about 0.5 are designed next to the ITO main channel. If the floating block and the channel are short-circuited, the value of a single point will exceed the 20% tolerance controlled by the program, resulting in functional failure losses. This design solution adds a 0.1 mm laser line, and the original floating block with a 0.5 spacing becomes two floating blocks (0.1 spacing and 0.4 spacing). Even if the first floating block with a 0.1 spacing is short-circuited with the channel, the measured value can still be covered within the 20% range without causing failure losses. At the same time, there are two laser lines for protection, thus improving the process yield.

[0017] Among them, the laser line is generated by the laser in the laser engraving machine.

[0018] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
