❓ Frequently Asked Questions
What is Incell LCD technology and how does it differ from regular LCD?
Incell LCD is an advanced display technology where the touch sensor layer is integrated directly into the LCD panel itself rather than being a separate layer laminated on top. In traditional LCD construction, the touch digitizer is a distinct component bonded to the LCD, creating a thicker overall assembly. With Incell technology, the touch sensing circuitry is built into the LCD during manufacturing, eliminating the separate touch layer and resulting in a thinner, lighter display. This integration provides several benefits for screen replacement. The thinner profile means easier installation with better fitment in the device chassis. The unified construction reduces the risk of panel cracking during installation that can occur when handling multi-layer assemblies. Touch response is often more direct because there are fewer layers between your finger and the LCD pixels. For iPhone 15 Pro Max repairs, the Incell LCD offers a cost-effective alternative to OLED while still delivering excellent visual quality with 120Hz refresh rate support. The technology produces displays with good viewing angles, color accuracy, and brightness suitable for everyday use.
Why might the screen need the 120Hz throttling fix?
The 120Hz throttling issue occurs because high refresh rate displays generate more heat than traditional 60Hz screens, and the iPhone's thermal management system may intervene to protect components. During maximum brightness use, prolonged continuous operation like extended gaming or video streaming, or use in extremely hot weather conditions, the LCD panel temperature can rise significantly. When the system detects elevated temperatures, it may automatically reduce the refresh rate to lower heat generation. This thermal throttling can cause temporary symptoms like screen freezing, display flickering, or unresponsive touch input until the temperature normalizes. The quick fix of enabling Limit Frame Rate in Settings forces the display to run at a consistent 60Hz, which generates less heat and avoids triggering the thermal protection system. This setting is found at Settings then Accessibility then Motion then Limit Frame Rate toggle to ON position. Running at 60Hz still provides smooth operation for most uses and eliminates the intermittent issues caused by thermal throttling. Many users find 60Hz perfectly acceptable for daily tasks and only notice the difference during fast gaming.
What is IC chip transfer and do I need it?
IC chip transfer refers to the process of removing the display integrated circuit chip from your original iPhone screen and soldering it onto the replacement LCD. This chip contains Apple's display authentication data, True Tone calibration information, and other identifiers that iOS uses to verify the screen. When the original IC chip is transferred to the new display, the iPhone recognizes it as a matched display, which can eliminate the "non-genuine display" warning in Settings and preserve True Tone functionality. However, IC chip transfer requires micro-soldering skills, specialized equipment including hot air rework stations and microscopes, and significant technical expertise. The chip is extremely small and delicate, and improper transfer can damage it permanently. Not all repair shops offer this service due to the skill and equipment required. The good news is that IC chip transfer is optional. This Incell LCD works perfectly without the transfer for all display functions including 120Hz refresh, touch response, brightness control, and color display. The only differences without IC transfer are the informational message in Settings and disabled True Tone. Most users find these acceptable trade-offs.
How does Incell LCD compare to OLED for iPhone 15 Pro Max?
OLED and Incell LCD each have advantages depending on your priorities and budget. OLED displays, like Apple's original Super Retina XDR, produce perfect blacks because each pixel emits its own light and can turn completely off. OLED also offers wider color gamut, better HDR performance, and thinner construction. However, OLED replacements cost significantly more than LCD options. Incell LCD uses a backlight behind the liquid crystal layer, which means blacks appear dark gray rather than true black, and the display is slightly thicker. But Incell LCD technology has improved dramatically, offering excellent color accuracy, high brightness, sharp 460 ppi resolution, and full 120Hz refresh rate support at a fraction of OLED cost. For most daily tasks including messaging, web browsing, social media, photography, and casual gaming, many users cannot distinguish Incell LCD from OLED in normal lighting conditions. The main differences become noticeable in dark environments viewing HDR content. If budget is a consideration and you primarily use your phone in typical lighting, Incell LCD offers excellent value. If color accuracy and deep blacks are critical to you, consider the OLED option.
Will Face ID continue to work after installing this LCD?
Yes, Face ID should continue to function after installing this Incell LCD, provided the installation is performed correctly by a qualified technician. The Face ID system, including the TrueDepth camera array with dot projector, infrared camera, and flood illuminator, is a separate module from the display and is not replaced during screen replacement. However, certain components related to Face ID function may need to be transferred from your original screen to the new LCD assembly, including the proximity sensor that detects when you raise the phone to your face. The earpiece speaker area where some Face ID components are mounted requires careful handling during the transfer process. If Face ID stops working after screen replacement, it typically indicates a loose connection, damage to the earpiece flex cable during installation, or accidental damage to the TrueDepth camera components rather than a problem with the LCD itself. Professional installation is strongly recommended because the delicate connectors and tight component spacing in iPhone 15 Pro Max require precision handling to avoid damaging Face ID functionality.
Will iOS show a warning message with this aftermarket screen?
Yes, when this Incell LCD is installed, iOS will display an informational message in Settings stating "Unable to verify this iPhone has a genuine Apple display" or similar wording. This message appears with any non-Apple-installed display regardless of quality. The message has no functional impact whatsoever on the display performance. Your LCD will work perfectly with full 120Hz refresh rate, accurate touch response, proper brightness control, and all other display functions. True Tone, which automatically adjusts color temperature based on ambient lighting, will be disabled because the calibration data is stored on the original display's IC chip. If IC chip transfer is performed during installation, the warning message can be eliminated and True Tone restored. However, many users find the display performs excellently without IC transfer and simply accept the informational message in Settings. This is purely cosmetic information Apple provides, similar to messages shown for non-genuine batteries or cameras. The aftermarket display will serve you well for all normal usage including apps, photos, videos, gaming, and everyday tasks.
What screen problems can this Incell LCD replacement fix?
This BQ7 Incell LCD assembly can resolve most touch screen and display issues caused by physical damage or component failure. Common problems it fixes include cracked or shattered front glass affecting display visibility and touch operation, completely black screen while the phone otherwise functions, unresponsive touch in certain areas or across the entire screen, ghost touching where phantom inputs register without physical contact, display flickering or unstable image output, vertical or horizontal colored lines across the display, dead pixels or areas not displaying correctly, reduced brightness or uneven backlight distribution, touch lag or delayed response to inputs, and discoloration or tinting of the display image. Because this is a complete assembly including the LCD panel and integrated touch digitizer, it replaces all display components that commonly fail from impact damage. However, if your issues are caused by logic board damage, damaged display connectors on the logic board, water damage to internal components, or software glitches, replacing the screen alone may not resolve the underlying cause. Professional diagnosis can help determine whether screen replacement will fix your specific issue.
Why is professional installation recommended for this screen?
iPhone 15 Pro Max screen replacement is one of the more complex smartphone repairs requiring specialized equipment and skills. The titanium frame design uses strong waterproof adhesive that needs controlled heat application to soften without damaging internal components or warping the frame. Multiple delicate flex cables with tiny ZIF connectors must be properly disconnected and reconnected without damage. The battery must be safely disconnected to prevent short circuits during the repair. Component transfer from the old screen requires handling small components with precision screwdrivers and careful attention. The LCD panel itself can be damaged by excessive pressure, static electricity, or improper handling during installation. Display flex cables can be torn if bent too sharply or pulled at wrong angles. If IC chip transfer is desired, micro-soldering skills and specialized equipment are required. Given the high value of the iPhone 15 Pro Max and the precision required for successful installation, we strongly recommend having the repair performed by qualified technicians with experience on this specific model and proper tools including heat stations and ESD-safe workstations.
