 ## Overview
 
-### Function Introduction
+### Functions
 
 The touchscreen driver powers on its integrated circuit (IC), initializes hardware pins, registers interrupts, configures the communication (I2C or SPI) interface, sets input configurations, and downloads and updates firmware.
 
-The touchscreen driver is developed based on the OpenHarmony input driver model, which applies basic APIs of the operating system abstraction layer (OSAL) and platform interface layer on the OpenHarmony Hardware Driver Foundation [(HDF)](../driver/driver-hdf-development.md). Common APIs include the bus communication APIs and OS native APIs (such as memory, lock, thread, and timer APIs). The OSAL and platform APIs shield the differences of underlying hardware. This allows the use of the touchscreen driver across platforms and OSs. In this regard, you can develop the touchscreen driver only once and deploy it on multiple devices.
