TFT Library
Thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin-film
transistor (TFT) technology to improve image quality (e.g., addressability, contrast).
TFT LCD is one type of active matrix LCD, though all LCD-screens are based on TFT active matrix addressing.
TFT LCDs are used in television sets, computer monitors, mobile phones, handheld video game systems, personal
digital assistants, navigation systems, projectors, etc.
The mikroBasic PRO for dsPIC30/33 and PIC24 provides a library for working with HX8347-D 320x240 TFT Lcd
controller.The HX8347-D is designed to provide a single-chip solution that combines a gate driver, a source driver,
power supply circuit for 262,144 colors to drive a TFT panel with 320x240 dots at maximum.
The HX8347-D is suitable for any small portable battery-driven and long-term driving products, such as small PDAs,
digital cellular phones and bi-directional pagers.
The following variables must be defined
in all projects using TFT library:
