BOE has developed an LCD solution that integrates an NFC antenna with in-cell touch. The design combines display, touch and NFC functions within the display assembly, supporting contactless interaction at the screen.
The solution uses a grid pattern to integrate the NFC coil on the TFT substrate.
The design adds a Tx signal line within the pixels to support touch and display driver integration (TDDI). To manage interference between NFC and touch signals, the driver uses time-division operation or noise filtering, depending on the NFC signal conditions.
For POS and mobile payment projects, antenna integration should be considered alongside the touch stack, reader electronics and enclosure. Contact our team to discuss application requirements and confirm available configurations.
