Anti aging process environment test of touch screen

Desert heat challenge
Customized process: Adding rare earth oxides to the conductive film to reduce the temperature coefficient of resistance from 0.3%/℃ to 0.08%/℃
Surface coating upgrade: using microcrystalline ceramic composite layer, reducing solar radiation absorption rate to 0.15
Actual test data: Operating continuously for 18 months at a surface temperature of 55 ℃ without any touch drift phenomenon
 

Breakthrough in extremely cold environment
Developing low-temperature OCA adhesive: maintains elasticity at -50 ℃ and has a peel strength of ≥ 15N/cm
Circuit antifreeze design: embed self heating copper wire in FPC flexible circuit board, automatically start insulation when temperature difference exceeds 30 ℃
Feedback from polar research team: In an environment of -45 ℃, the touch response speed is only 8% slower than at room temperature
 

Chemical corrosion test
We have innovatively launched:
Fully sealed border process: Fill the screen edge with liquid silicone to achieve IP69K protection level
Corrosion resistant conductive film: By doping indium zinc oxide (IZO), the acid resistance is increased by 10 times
 

After the transformation of the DCS control system in a certain chemical plant, the touch screen operated stably for 5 years in corrosive gases with a pH of 2-12, and the maintenance rate decreased by 90%. These positive reports from real scenes are the best endorsement of anti-aging technology.
