COF (Chip on Film) |
COB (Chip on Board) |
| structruer |
The IC is bonded onto the flexible FPC cable, with no additional PCB required. |
The IC is directly bonded onto a rigid PCB board, which is connected to the sensor. |
| Bezel |
Ultra-narrow bezel, available in narrow-bezel or borderless designs. |
Relatively wide bezel; limited by PCB space occupation, narrow bezel design is restricted.
|
| Thickness |
Slimmer design with reduced overall thickness, ideal for thin-profile structures. |
Larger thickness; the PCB increases overall thickness. |
| Wiring Flexibility |
FPC is bendable with flexible routing directions, making it suitable for complex structures. |
Fixed cable outlet, poor wiring flexibility, and limited installation. |
Vibration / Impact Resistance
|
Flexible connection for better vibration resistance. |
Rigid PCB, average vibration resistance, susceptible to vibration interference. |
| Signal |
Shorter circuit, less interference, and high touch accuracy. |
Longer circuit path, relatively weaker anti-interference capability. |
| Cost |
more higher |
cost-effective |
| Applications |
Industrial control, automotive, medical, narrow-bezel all-in-one machines, outdoor equipment |
Ordinary home appliances, consumer tablets, conventional commercial displays, low-cost devices |
| Life time |
Suitable for wide temperature ranges and long-term continuous operation. |
Suitable for general environments; performance in harsh conditions is average.

1.In
medical applications, screens are frequently wiped with alcohol for disinfection. Ordinary screens are prone to corrosion and poor durability. To address these issues, we have adopted OCA optical adhesive resistant to 75% ethanol, IPA, and quaternary ammonium salts in material selection.
2.The cover glass is coated with a medical-grade anti-fingerprint (AF) coating.
3.The surface is treated with AG+AR composite processing to reduce glare, improve light transmittance, lower reflectivity, and make the screen clearer and more transparent.
4.The screen border ink is matte-finished to prevent harsh reflection from shiny edges and smudge visibility. The border ink is also protected with alcohol-resistant AF coating.
5.Equipped with a medical-grade, high signal-to-noise ratio touch controller, supporting water rejection, disinfectant film resistance, and operation with gloves (including thick gloves).
6.Adopts large water droplet filtering and edge false-touch shielding anti-interference mechanisms, preventing accidental triggers from water stains and reducing erratic jumps caused by border oil contamination.
7.The touch signal threshold and sampling rate are increased to reduce signal drift caused by oil contamination and conductive disinfectants.
FAQ1.Can this touch screen withstand frequent disinfection with 75% alcohol, IPA, and quaternary ammonium salts?Yes. It uses special medical-grade OCA optical adhesive and alcohol-resistant AF coating, providing excellent resistance to common medical disinfectants.
2.Does the screen still respond accurately when wearing gloves or with water droplets on the surface?Yes. The high-SNR medical-grade touch controller supports operation with gloves (including thick gloves), water droplets, and disinfectant film without misoperation.
3.Will the screen reflect strongly under bright lighting or medical lighting?No. The surface features AG+AR composite treatment, and the border uses matte ink, effectively reducing reflection, glare, and eye fatigue.
4.How does this touch screen avoid false touches caused by water stains or oil contamination?It supports large water droplet filtering, edge false-touch prevention, higher signal threshold, and higher sampling rate to stabilize signals and avoid drift or random jumping.
5.In what medical scenarios is this 10.1-inch touch screen suitable?It is widely used in medical devices, bedside terminals, diagnostic equipment, operating room controls, and other healthcare equipment requiring frequent disinfection and high reliability.
