Description

Technical Field

[0001] The utility model relates to an OGS touch screen, more specifically, to a semi-transmissive ink silk-screen printing component of an OGS touch screen. Background Art

[0002] At present, many car central control screens and instrument screens have many touch buttons. These buttons generally have two effects: semi-transparent effect and opaque effect. In order to achieve consistent button display colors, the colors of these two effects are generally designed to be the same color, such as opaque white and semi-transparent white, opaque gray and semi-transparent gray, semi-transparent red and opaque red, etc. The general OGS touch screen process is: yellow light on white glass to make the first layer BM (hollow button area) → then make the touch function layer → screen print semi-transparent ink → then screen print opaque ink → then screen print reverse cover black ink (avoid the semi-transparent button area) → screen print alignment line and character mark ink. This ink stacking solution has a long process and a relatively low screen printing yield.

[0003] Chinese utility model patent document CN205015864U discloses a touch screen, including a cover plate, a black frame layer arranged on the lower surface of the cover plate, and a touch sensing layer bonded to the cover plate and the black frame layer, wherein a hidden light-transmitting hole is formed on the black frame layer, and a semi-transparent ink layer is arranged on the touch sensing layer at a position corresponding to the hidden light-transmitting hole. The semi-transparent ink layer is a white ink layer. The thickness of the semi-transparent ink layer is 2-20 μm, and the transmittance of visible light passing through the semi-transparent ink layer through the hidden light-transmitting hole is 1%-7%. The area of ​​the semi-transparent ink layer is larger than the area of ​​the hidden light-transmitting hole. The hidden light-transmitting hole is an indicator hole, a strong light hole, a key pattern or a logo pattern. At least one of a transparent hole, a through hole and an infrared sensing hole is also arranged on the cover plate and the black frame layer. The black frame layer includes a first ink layer and a second ink layer, the first ink layer is located between the cover plate and the second ink layer, a vacancy is arranged on the first ink layer at the hidden light-transmitting hole, and the second ink layer covers the vacancy.

[0004] Obviously, the patent sets a semi-transparent ink layer on the touch sensing layer to block the light directed to the hidden light-transmitting hole to prevent the excessive light transmittance from causing discomfort to the human eye. This structure cannot solve the problem of the existing ink stacking solution with a long process and relatively low silk screen yield.

[0005] Chinese utility model patent document CN220252556U discloses a touch screen assembly with semi-transparent holes, wherein the touch screen assembly with semi-transparent holes comprises a glass cover plate, a light-shielding ink layer is provided on the surface of the glass cover plate, a semi-transparent key area is provided on the light-shielding ink layer, and a plurality of penetrating light-transmitting holes are provided on the semi-transparent key area. The thickness of the light-shielding ink layer is 2 to 4 μm. The thickness of the light-shielding ink layer is 3 μm. The surface of the semi-transparent key area is flush with the light-shielding ink layer. A transparent light-transmitting layer is provided on the surface of the semi-transparent key area. The light-transmitting layer is a PET film. The thickness of the PET film is 10 to 20 μm. The thickness of the PET film is 15 μm. The light-transmitting holes are filled with PET. The filling depth of the PET is adapted to the depth of the light-transmitting holes.

[0006] Obviously, the touch screen group containing semi-transparent holes in this patent directly makes the semi-transparent part on the exposure ink, thereby reducing the process steps. This method cannot solve the problems of the existing ink stacking solution with a long process and relatively low silk screen yield. Utility Model Content

[0007] Based on this, it is necessary to provide an OGS touch screen semi-permeable ink screen printing component for the above technical problems. The OGS touch screen semi-permeable ink screen printing component comprises a VA area white glass layer, a touch function layer is arranged on the lower surface of the VA area white glass layer, a hollow key module is arranged on one side of the VA area white glass layer, the hollow key module comprises a hollow key glass layer, a yellow light layer is arranged on the lower surface of the hollow key glass layer, a touch extension layer is arranged on the lower surface of the yellow light layer, a black reverse black ink layer is arranged on the lower surface of the touch extension layer, and a position mark ink layer is arranged on the lower surface of the reverse black ink layer, wherein a semi-permeable key ink area is arranged in the yellow light layer. The OGS touch screen semi-permeable ink screen printing component changes from the conventional scheme of screen printing 4 layers of ink to screen printing 3 layers or 2 layers of ink, which reduces the number of screen printing times, shortens the process flow, improves the screen printing yield, and saves the cost of one or two screen printing meshes.

[0031] As described in the background technology, the existing technology for vehicle-mounted central control screens and instrument screens is that many vehicle-mounted central control screens and instrument screens have many touch buttons. These buttons generally have two types of semi-transparent effects and opaque effects. In order to achieve consistent button display colors, the colors of these two effects are generally designed to be the same color, such as opaque white and semi-transparent white, opaque gray and semi-transparent gray, semi-transparent red and opaque red, etc. The general OGS touch screen process is: yellow light is used on white glass to make the first layer BM (hollow button area) → then the touch function layer is made → screen printing semi-transparent ink → then screen printing opaque ink → then screen printing reverse cover black ink (avoiding the semi-transparent button area) → screen printing alignment lines and character mark ink. This ink stacking solution has a long process and a relatively low screen printing yield.

[0032] In order to solve this technical problem, the utility model provides an OGS touch screen semi-transparent ink silk screen component comprising a VA area white glass layer 1, a touch function layer 2 is provided on the lower surface of the VA area white glass layer 1, a hollow key module 3 is provided on one side of the VA area white glass layer 1, the hollow key module 3 comprises a hollow key glass layer 31, a yellow light layer 32 is provided on the lower surface of the hollow key glass layer 31, a touch extension layer 33 is provided on the lower surface of the yellow light layer 32, a black reverse cover black ink layer 34 is provided on the lower surface of the touch extension layer 33, a registration mark ink layer 35 is provided on the lower surface of the reverse cover black ink layer 34, wherein a semi-transparent key ink area 36 is provided in the yellow light layer 32.

[0033] Through the above structural design, the semi-transparent ink screen printing component of the OGS touch screen changes from the conventional scheme of printing 4 layers of ink to printing 3 or 2 layers of ink, which reduces the number of screen printing, shortens the process flow, improves the screen printing yield, and saves the cost of one or two screen printing meshes. Since the semi-transparent key ink area 36 is added with the black reverse cover black ink layer 34, it will become an opaque key ink, with high clarity and good recognition.
