TFT 16-bit 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 mikroPascal PRO for FT90x provides a library for working with the following display controllers :
- Himax HX8347D, HX8347G and HX8352A,
- Solomon Systech SSD1963,
- Ilitek ILI9340, ILI9341, ILI9342 and ILI9481.
Note :
- All display controllers are initialized with 65,536 colors (RGB 565 format) and require two full ports for operation (due to the 16-bit interface).
