Large Touch Screen Display EETI Controller | Manufacturer

Outdoor extreme environments test touch stability, structural firmness and long-term durability of touch screens.

Specifications:

How to solve touch failure in low temperature and coordinate drift in high temperature outdoors?
1.Adopt wide-temperature dedicated touch chip, supporting full operating range of -40℃~85℃. Built-in temperature drift compensation algorithm prevents low-temperature touch failure and high-temperature coordinate drift.

2.Adopt high and low temperature resistant OCA glue to offset thermal expansion and contraction stress, avoiding delamination and cracking of full bonding layers.

3.Adopt temperature-resistant tempered glass and flexible heat-resistant FPC, no deformation under sudden temperature changes, avoiding black screen and touch interruption faults.

4.Reserve expansion gaps to buffer thermal deformation tension, preventing touch layer damage caused by shell pulling.

5.Undergo extreme temperature cycling test before delivery to eliminate defective products with temperature variation issues.

How to prevent aging caused by outdoor ultraviolet rays?
1.Electrodes are coated with anti-corrosion layer, and FPC undergoes three-proof coating to block salt spray erosion and oxidation.

2.Adopt UV-resistant substrate to slow cover yellowing and light transmittance reduction.

3.Special anti-UV ink resists fading, cracking and peeling under prolonged sunlight.

4.Seal gaps with rubber rings to block moisture and salt spray infiltration.

5.All components adopt weather-resistant raw materials to reduce touch performance attenuation under long sun exposure.

6.Accelerated salt spray and UV aging tests ensure long-term stability for outdoor coastal use.

How to enhance visibility under strong outdoor sunlight?
1.High brightness screen over 1000cd/m² delivers clear visuals under strong sunlight.

2.Surface atomization disperses direct light and eliminates harsh mirror reflection.

3.Reduce light reflectivity and raise light transmittance to maintain image contrast.

4.Optimize screen background and UI color scheme for distinct interface layers under strong light.

5.Light sensor enables automatic brightness adjustment adapting to ambient light intensity.

FAQ
1.Will black screen or touch failure occur in high and low temperature environments?
Adopted temperature-resistant glass and flexible FPC structure, hardly deformed under sudden temperature changes to avoid touch malfunctions.

2.Will the panel turn yellow or fade after long-term outdoor exposure?
Equipped with UV-resistant substrate and special ink to slow aging, keeping patterns intact without fading or cracking.

3.Can it work steadily in humid and salty coastal areas?
Anti-corrosion electrode coating, three-proof FPC coating and rubber ring sealing effectively resist moisture and salt spray corrosion.

4.Is the screen visible clearly under intense sunlight?
1000cd/m² high brightness screen with anti-reflection treatment ensures clear display, supporting automatic light adjustment.

5.Is the service life guaranteed for outdoor application?
Strict temperature cycling, salt spray and UV aging tests are conducted before delivery for reliable outdoor durability.
