1. Three Levels of Post-drop Screen Damage
Grade 1: Only outer glass cracked with intact display → replace copper foil digitizer alone. Grade 2: Crack plus screen dark lines or spots → replace full LCD and digitizer assembly. Grade 3: Bent middle frame → calibrate the frame before installing new screens to avoid secondary damage.
2. Copper Foil Digitizer Identification & Advantages
Premium digitizers are equipped with conductive copper foil at the flex root for electromagnetic interference shielding, which greatly reduces spontaneous ghost touch. Ordinary digitizers without copper foil are more likely to have touch errors, especially in complex power environments.
3. Model Difference for Wholesale Matching
iPad Air 5 (A2588) has different pin definitions on the touch connector compared with Air 4 (A2316). Parts for two models cannot be mixed randomly, even if they look the same. Classify goods clearly during bulk packaging and delivery for global wholesale.
