Apple is internally developing touch and display driver integration (TDDI) single-chip solutions for its iPhones, according to sources in Taiwan's IC design industry. The TDDI single-chip solutions will also come with integrated fingerprint sensors, said the sources. The integrated design would fit into future iPhone designs – models with ultra-thin and ultra-narrow displays, and with a whole plane design eliminating the Home button.
DigiTimes notes that the expansion of Apple's in-house design business could have a significant impact on the global semiconductor industry. Apple already develops CPUs for its mobile products including the Ax and Sx line of SoCs.
