Problems solved by technology

[0008] The traditional color OGS production process is complicated, and the requirements for color inks are extremely high, high temperature resistance and non-yellowing are required, and the ink particles are required to be fine.
The normal production process is large screen printing color ink and cover ink, the thickness of which is 30~50um, followed by the production of sensors, such as ITO coating, ITO development, stripping, OC baking and other processes, the temperature exceeds 250 degrees , leading to poor appearance of color inks such as easy carbonization and yellowing at high temperatures, and consumers cannot accept this appearance product
In addition, the ITO electrode layer needs to climb more than 30um ink layer height difference to realize the sensing function. The thickness of ITO itself is 0.02~0.04um, which makes ITO easily break at the climbing point, resulting in functional failure, very low yield and high cost.

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with specific embodiments.

[0048] Such as figure 1 image 3 As shown, the color capacitive touch screen includes a chemically strengthened glass substrate 11 with a thickness between 0.5mm and 2.0mm (resin material substrates can also be used), and ITO electrodes 12 and black resin layers laminated on the transparent substrate in sequence. 13. Carbon paste 14, color ink layer 15, cover ink 16, silver paste 17, black cover ink 18; the ITO electrode is a horizontal or vertical conduction electrode, and has a regular pattern structure; the ITO electrode includes a capacitor Screen drive (ITO electrode 1) and sensing electrode (ITO electrode 2), ITO electrode 1 and ITO electrode 2 are on the same layer, independent of each other, insulated from each other, and interleaved design. The transparent substrate includes a window area 21 and a non-window area 22, and a black resin layer and a colore...

Abstract

The invention discloses a color capacitive touch screen and a manufacturing method thereof. The color capacitive touch screen comprises a transparent substrate, and an ITO electrode, a black resin layer, carbon paste, a color ink layer, bottom covering ink, silver paste and black bottom covering ink which are stacked on the transparent substrate sequentially; the ITO electrode comprises a capacitive screen drive and a sensing electrode and is in a regular-pattern structure; the capacitive screen drive and the sensing electrode are located in the same layer independently in an insulated manner and are designed to be perpendicular. By means of the stacked structure of the capacitive touch screen and reasonable design of an ITO conductive scheme, the color capacitive touch screen is obtained, touch screen production process procedures are reduced, and production cost of the touch screen is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of capacitive touch screens, in particular to a color capacitive touch screen and a manufacturing method thereof. Background technique [0002] With the development of electronic technology, the keyboards or mice of mobile phones, digital cameras, handheld game consoles, car DVDs, MP3s, instruments, etc. are gradually replaced by touch screens. Touch screen products were not very popular a few years ago, but as people have more and more contacts with touch screen products, they have been recognized by more people in the past two years, and the development speed has gradually accelerated. The rapid growth of touch screen has not only aroused more fierce competition in the industry, but also indirectly promoted the development of technology. Its multi-touch operation method has raised the influence of touch screen products to a new level, and has gradually been recognized by people. Pay attention. [0003]...
