You might remember the story of Chinese glass manufacturer BOE. The company wanted to be an iPhone supplier so badly and it started working its way up the ladder. First, it supplied replacement OLED panels for units in need of new glass. That gave Apple the confidence to allow BOE to supply some iPhone 12 units and supposedly the company was given the opportunity to supply Apple with up to 40 million displays for a variety of iPhone models.

Seeking to improve its production yields, BOE unilaterally changed the specs on the 6.1-inch panels it was building

BOE was hoping to supply Apple with 30 million OLED panels for the 6.1-inch iPhone 14.. But the company decided to make unilateral changes to the panel's specs without informing Apple. BOE reportedly changed the width of the thin-film transistors used on the panels without getting Tim Cook-or anyone from Apple-to sign off on it. We will discuss the probable reason why this was done in a few paragraphs.
