2.4-inch TFT liquid crystal touch screen module is a common small
display device. With a brightness of 180Cd/m², it is suitable for
general indoor environments. Here is an introduction to this
display screen:
Basic dimensions: 2.4 inches refers to the diagonal length of the
screen, approximately 6.1 centimeters. Its module structure is thin
and light, with a thickness usually not exceeding 3mm. The
mainstream effective display area size is approximately
36.72mm×48.96mm.
Display technology: TFT stands for Thin Film Transistor technology.
Each pixel point is equipped with an independent switch device,
enabling high-speed refresh and precise color control. Compared to
traditional STN screens, it has advantages such as faster response
speed, higher contrast ratio, and more realistic color
reproduction.
Resolution: The mainstream resolution is 240×320 (QVGA), which can
provide good clarity and display detail on a 2.4-inch screen,
suitable for information display and graphical interface
applications.
Brightness and contrast: The brightness of 180Cd/m² is at a medium
level, suitable for use in environments with weak light such as
indoors, and can clearly display content. In terms of contrast,
different products vary, with the contrast of most TFT liquid
crystal touch screen modules ranging from 250:1 to 500:1, enabling
the image to have a certain level of depth and color vividness.
Viewing angle: Generally, TFT screens without IPS material have
limited viewing angles. The upper and lower viewing angles may be
around 50°, and the left and right viewing angles are around 70°.
However, IPS material has viewing angles of 178° up, down, left,
and right.
Interface type: Common interfaces include SPI, 8080 parallel port,
etc. These interfaces can be conveniently connected to mainstream
microcontrollers such as STM32, ESP32, etc., for data transmission
and display control.
Touch screen type: There are two types: resistive and capacitive.
Resistive touch screens achieve touch operations through pressure
sensing, with lower cost; capacitive touch screens work by sensing
the human electric field, providing more sensitive operation and
supporting multi-touch.
Operating temperature: Most 2.4-inch TFT liquid crystal touch
screen modules operate within a temperature range of -20°C to
+70°C, having certain environmental adaptability, and can work
stably within a wide temperature range.
Application fields: Due to its small size, light weight, and low
power consumption, it is widely used in portable devices,
industrial control, medical instruments, smart home, etc., such as
smart locks, handheld detectors, blood pressure monitors,
electronic photo albums, etc.
