July 2020AN4861 Rev 31/961AN4861 Application noteLCD-TFT display controller (LTDC) on STM32 MCUs IntroductionThe evolution of the mobile, industrial and consumer applications leads to a stronger need of graphical user interfaces (GUIs) and to an increase in the required hardware resources. These applications require higher quality graphics, more hardware and software resources (like memory for graphical primitives or framebuffer) and higher processing performances. To respond to this increasing demand, microprocessor units are often used, which leads to a higher costs and to more complex designs with longer time to market. To face these requirements, the STM32 microcontrollers (MCUs) offer a large graphical portfolio. Thanks to their embedded LCD-TFT display controller (LTDC), the STM32 MCUs allow high-resolution display panels to be directly driven, without any CPU intervention. In addition, the LTDC can access autonomously to internal memories or external memories to fetch pixel application note describes the LCD-TFT display controller of the STM32 MCUs listed in the table below, and demonstrates how to use and configure the LTDC peripheral.
controller can be embedded either in the display module or in the MCU. • The display glass is driven by the display controller and is responsible to display the image that is composed of a matrix of pixels. A display is characterized by: – Display size (resolution): is defined by the number of pixels of the display that is ...
