2.4-inch IPS TFT LCD display with a resolution of 240×320 pixels, featuring a SPI interface and equipped with CTP (capacitive touch screen), is a common display module found in portable electronic devices. Here is a detailed introduction to it:
Dimensions and Resolution: The diagonal size of this display is 2.4 inches, with a resolution of 240×320 pixels. This means that within its display area, there are 240 pixels in the horizontal direction and 320 pixels in the vertical direction, providing relatively clear image display, suitable for showing simple graphics, text information, etc.
Display Technology: It adopts IPS (In-Plane Switching) technology, featuring full-view characteristics, meaning that the color and image distortion is minimal when viewed from any angle, ensuring good visual effects in different viewing angles, suitable for multiple people watching simultaneously or scenarios requiring frequent changes in viewing angles.
Interface Type: It is equipped with a SPI (Serial Peripheral Interface) interface, a serial communication interface with fewer pins, simple connection, and fast data transmission speed, which can be conveniently connected to microcontrollers and other master control chips to drive and control the display, commonly used in embedded systems.
Capacitive Touch Screen (CTP): It integrates a capacitive touch panel, supporting touch operations. Users can achieve various interaction functions by touching the screen with their fingers, such as clicking, sliding, zooming, etc. The capacitive touch screen has fast response speed, high touch accuracy, and supports multi-touch, providing a more smooth touch experience.
Driver Chip: Common driver chips include ST7789T3, ST7789VI, etc. These chips are responsible for controlling the pixel points of the display to light up, display colors, and refresh images, ensuring the display can work normally and present high-quality images.
Brightness and Contrast: The brightness of different models of this type of display varies, generally ranging from 298nits to 600nits. The high brightness can ensure that the screen content remains clearly visible in bright environments; the contrast is usually at a good level, such as 500:1, which can make the image colors more vivid and the layers more distinct.
Operating Temperature: The general operating temperature range is -20℃ to 70℃, capable of adapting to certain temperature changes, and can work normally in a wide range of temperature conditions, suitable for various different application scenarios.
Form Size: The form size of the display produced by different manufacturers may vary, such as 53.87mm×82.2mm×3.85mm, 42.8mm×59.91mm×4.13mm, etc. Its compact size makes it suitable for integration into various small devices.
