Using an original display in a MacBook after it has been broken is important for several reasons:

• Compatibility: Using an original display ensures that the replacement part is compatible with your MacBook model and will work correctly with the rest of the hardware.
• Quality: Original displays are manufactured to meet Apple's standards for quality and performance, so you can expect reliable and accurate color reproduction, brightness, and other features.
• Warranty: If you use an original display and encounter any issues, your MacBook's warranty may still be valid. Using a third-party or counterfeit display may void your warranty and make it more difficult to get repairs or support from Apple.
• Integration: Original displays are designed to integrate seamlessly with your MacBook's logic board and other components. Using a third-party display may result in compatibility problems that could affect the performance of your MacBook.

In summary, using an original display in a MacBook after it has been broken is important for ensuring compatibility, quality, warranty protection, and seamless integration with the rest of the hardware.
