iphone 4 lcd screen in stock
Depending on your location, you can get your iPhone display replaced—in or out of warranty—by visiting an Apple Store or Apple Authorized Service Provider, or by shipping your iPhone to an Apple Repair Center. Genuine Apple parts are also available for out-of-warranty repairs from Independent Repair Providers or through Self Service Repair.*
The iPhone display is engineered together with iOS software for optimal performance and quality. A nongenuine display might cause compatibility or performance issues. For example, an issue might arise after an iOS software update that contains display updates.
* Independent Repair Providers have access to genuine Apple parts, tools, training, service guides, diagnostics, and resources. Repairs by Independent Repair Providers are not covered by Apple"s warranty or AppleCare plans, but might be covered by the provider"s own repair warranty. Self Service Repair provides access to genuine Apple parts, tools, and repair manuals so that customers experienced with the complexities of repairing electronic devices can perform their own out-of-warranty repair. Self Service Repair is currently available in certain countries or regions for specific iPhone models introduced in 2021 or later. To view repair manuals and order parts for eligible models, go to the Self Service Repair page.

The second B2B connector is to the touch screen controller. Also 1v8 SPI. During initialization, the touchscreen and host exchange packets of about 80K bytes which tends to rule out using a smaller microcontroller.
During a touch, the touchscreen will generate an interrupt every 16ms.The host reads 8 bytes which include the length of the payload packet. The payload is 55 bytes for one finger, 83 for two, etc, and has a simple checksum. On the iPhone, the host runs it at a bit clock of 12 Mhz, but I imagine slower would be fine.
