Problems solved by technology

[0003] The disadvantage of the above design method is that: the marks at both ends are symmetrical, and in the production process, the equipment only plays a single role of overlapping alignment
Due to the particularity of the transparency of the material, it is necessary to use a strong light to identify the ITO surface. People repeat this work under strong light for a long time, which can easily cause eye fatigue.
Secondly, once the ITO conductive surface is identified incorrectly, the FPC will be crimped on the non-ITO conductive surface, causing the FPC to be scrapped and reworked

Embodiment Construction

[0023] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The present invention is achieved in this way, a production method for error-proof crimping of a display panel, the method comprising the following steps:

[0025] (1) Set the ITO glass anti-error mark: set the first alignment anti-error mark and the second alignment anti-error mark on the surface of the ITO glass with the PIN bit, the first alignment anti-error mark and the second alignment anti-error mark The error marks are respectively located on both sides of the PIN bit, and are arranged asymmetrically with respect to the PIN bit; the asymmetric arrangement means that the size, position and spacing of the first pair of error prevention marks and the second pair of error prevention marks are different, Instead of the original overlapping alignment, it is easier to judge; this makes the alignment crimping position unique, and also...

Abstract

The invention discloses a mistake proofing crimping production method of a display panel, a structure of the display panel, and the display panel. The production method is characterized in that the alignment mistake proofing marks, asymmetrically distributed along PINs, on ITO glass and a flexible printed circuit board can be quickly recognized and aligned by using existing recognizing equipment; the production method is simple, the operability is strong, each alignment mistake proofing mark on the ITO glass is formed by four square structures uniformly distributed at intervals; the mistake proofing alignment marks on the flexible printed circuit board adopt the corresponding crossed structures; ITO conductive surface marks with the asymmetrical structures adopt G-shaped structures; the ITO conductive surfaces can be easily recognized with naked eyes by the ITO conductive surface marks, so that the judgment time in recognizing the ITO conductive surfaces manually is saved, manual judgment in spot check or analysis is also facilitated, accordingly, the multiple mistake proofing is achieved, and besides, the production efficiency is improved when the crimping production correction rate is improved.

Description

technical field [0001] The invention relates to the manufacturing field of display panels, in particular to a production method and structure of a wrong-proof crimping of a display panel and a display panel with the wrong-proof crimping structure. Background technique [0002] In the production process of pressing FPC (flexible circuit board) for liquid crystal display panels and touch screen panels, since the PITCH value of pressed FPC products is generally small, the alignment requirements are very high. Usually, a section of 0.2 The horizontal bar of mm or 0.3mm is used as the alignment mark when ITO glass and FPC are crimped, and the shape of the mark on the left is The shape of the marker on the right is Its design size and position are completely symmetrical. Use the camera to capture the fixed visible area during alignment and Marking, through the camera system, the alignment marks on the left and right sides of the FPC are enlarged and displayed on the monito...
