21.5 Inch USB G+G 10 Points PCAP Capacitive Touch Scren Panel
21.5 Inch ILI2510 10Points G+G Cap Touch PCAP Capacitive Touchscreen
The 21.5 Inch Touch Panel (Model No. WTY215599A01) is a G+G structure capacitive touch panel, which is composed of a cover glass, sensor glass, driver IC and FPC.It is driven by a ILITEK IC Chip ILI2510, which utilizes USB interface and supports 10 points touch.
Advantages of Capacitive Touch Panel (Capacitive Touch Screen / Capacitive Touchscreen / PCAP Touch Panel): Only needs to be touched lightly, without any pressure to generate a signal. Only needs one time or no calibration at all after production. Supporting small and medium touch screens and supports gesture recognition and multi-touch. Being wear-resistant, has a long service life, and has low maintenance costs when use it.

Capacitive Touchscreen Panel manufacturing process
1. Glass Preparation: The first step in the manufacturing process is to prepare the glass substrate. The glass substrate is cleaned, and a conductive coating is applied to the surface. The conductive coating is usually made of indium tin oxide (ITO) and is deposited using a process called sputtering.
2. Photolithography: After the conductive coating has been applied to the glass substrate, a photoresist layer is applied over it. The photoresist layer is then exposed to UV light through a mask, which creates a pattern on the conductive coating.
3. Etching: The next step is to etch the conductive coating using a chemical solution. The photoresist layer protects the conductive coating in areas where it is not exposed to UV light, allowing the conductive coating to be selectively removed in areas where the photoresist has been exposed to UV light.
4. Cleaning: After the etching process is complete, the remaining photoresist layer is removed, and the glass substrate is cleaned to remove any remaining contaminants.
5. Sensor Assembly: The next step is to assemble the touch sensors. This involves attaching a layer of adhesive material to the glass substrate and then placing the touch sensors on top of the adhesive layer.
6. Cover Glass Lamination: After the touch sensors have been assembled, a cover glass is laminated onto the surface of the touch sensors using a layer of adhesive material. The cover glass is usually made of tempered glass, which is strong and scratch-resistant.
7. Testing: Once the touch panel is assembled, it undergoes rigorous testing to ensure that it meets the required performance specifications. This includes testing for touch sensitivity, response time, and accuracy.
8. Final Assembly: Finally, the touch panel is integrated into the device it was designed for, such as a smartphone or tablet.
