Display Screen Separation (Mobile/Tablet LCD Maintenance)
Suitable for the maintenance process of mobile phones, tablets and industrial control large screens. Precise constant temperature heating softens OCA optical adhesive to separate touch layers and liquid crystal layers stably. The platform heats evenly without backlight burn or driver IC damage, greatly improving the yield rate of screen repair and adapting to the rework of various sizes of screens.
Case 1: Broken Screen Separation for Smartphones
Application Scenario:
The OCA optical adhesive of Apple and Android smartphones hardens at room temperature, which cannot be separated manually. Forcible separation easily causes liquid crystal cracking and backlight damage during outer screen replacement.
Practical Solution:
Set the constant temperature heating platform to 80–100℃, place the mobile phone flat and heat for 3–5 minutes to fully soften the OCA adhesive. Separate the inner and outer screens easily with special steel wire. Uniform heating effectively avoids liquid crystal breakage, backlight burn and screen deformation, and significantly improves the repair yield.
Case 2: Large Screen Assembly Rework for Industrial Tablets
Application Scenario:
10-inch industrial control tablets suffer from touch failure and drift, requiring separation of touch and liquid crystal layers. Uneven heating of large screens easily burns driver ICs and damages liquid crystal modules.
Practical Solution:
Adopt an extended large-size constant temperature heating platform with a stable temperature of 95℃. Lay the tablet screen flat for overall uniform heating to avoid local high temperature damage to the driver IC. Gently soften the adhesive for layered disassembly, increasing the repair yield by more than 90% without any screen damage.
