stm32 tft lcd interface price

TFT stands for thin-film-transistor and is a variant of LCD displays with an active matrix. LCD-TFTs are widely used in embedded products as they are available in many different resolutions, sizes, interfaces, price ranges, etc.

Some variants of TFT-LCDs are TN and IPS panels. Examples of IPS TFT-LCDs, is the STM32F769 DISCO and STM32H747 DISCO, both running a 800*480 MIPI-DSI TFT IPS LCD display.

eInk displays are low color displays, ideal for applications with low power consumption needs, wide viewing angles, and easy readability. TouchGFX Implementer SDATAWAY demonstrates an eInk display running an TouchGFX application on a STM32F412 here: https://www.touchgfx.com/cases/e-ink/

The display is connected to the MCU via different types of interfaces. The display interfaces vary on different parameters, and the section below addresses the graphics related parameters like number of pins needed, max bandwidth supporting different resolutions.

TouchGFX can use any display interface, and STM32 microcontrollers offer a wide range of display interfaces connecting to Motorola 6800, Intel 8080, SPI, RGB-TFT, and MIPI-DSI.Interface# of pinsTarget resolutionsMax bandwidthBenefitsDisadvantagesSPI4*Up to 480*27216 MHzSimple hardware interface, faster than I2C,

Pixel density defines how many pixels are shown per inch or square inch. Choosing the right pixel density can depend on the expectations from the end user, environment, design needs etc. Putting this into perspective, a high-end mobile phone runs a 6.1” 2340x1080 with a pixel density per square inch of 178,500, while a commonly used 5” TFT display running 800x480 has 34.816 Pixels per square inch.

For some applications it can be difficult seeing any difference, unless the display is being looked at very closely. Examples of pixels densities are: STM32F476DISCO with 16,462 PPI2 and STM32F769DISCO with 54,400 PPI2.

Displays with either Motorla 6800, Intel 8080, SPI, or MIPI-DSI interfaces usually embed RAM (GRAM), which has the size of 1 full framebuffer. These types of displays can connect to the MCU via SPI, FMC or DSI-host(LTDC). A second RAM (framebuffer) is required externally to the display RAM and this can be in the MCU or in external RAM.

As the display is the face of your embedded graphical user interface product, adding a cover lens could improve the look and feel. The cover lense can improve the design, scratch resistance, impact strength, colors, etc.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 2.8"TFT Touch Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

It is a 2.0 inch TFT display module.TFT liquid crystal has a semiconductor switch for each pixel,and each pixel can be directly controlled by dot pulses,so each node is relatively independent and can be continuous...
