What are the main resolutions and interfaces of a 4.3-inch LCD screen?
Date:2025-05-22
Previously, we introduced the widely used industries of 4.3-inch LCD screens. Today, we will introduce the main resolutions and interface types of 4.3-inch LCD screens:
I. Main resolution
1. 480×272（WQVGA）
-This is the most common resolution, suitable for industrial control, instrument display and other scenarios, with
a typical brightness range of 280-350 cd/m ², and some models can reach up to 700 cd/m ².
-Some products support IPS full view technology, with a viewing angle of over 80 °.
2. 800×480（WVGA）
-High definition resolution, suitable for scenarios that require high display accuracy, such as industrial control
equipment and vehicle instruments. Brightness can reach 500-1000 cd/m ², with better visibility under sunlight.
II.Main interface types
1. RGB interface
-24 bit parallel RGB: widely supported, suitable for scenarios where MCU or MPU comes with an LCD controller,
such as Tianma P0430WQF1ME00 (40 pin FPC), Waveshare 24PIN parallel interface module.
-8/16 bit MCU interface: Some modules have built-in controllers (such as SSD1963), simplifying driver design
and supporting single power supply.
2. LVDS interface
-Suitable for scenarios with high requirements for long-distance transmission and anti-interference, such as
industrial control instruments. For example, INNOLUX AT043TN25 V.2/AT043TN24 V.7 module.
3. UART serial port
-The serial port screen supports interface development through UART communication, reducing the occupation
of main control resources and suitable for rapid development of human-computer interaction interfaces.
4. Touch screen interface
-Resistive touch: A 4-wire resistive screen is usually used, which requires an external ADC or touch controller
(such as XPT2046).
-Capacitive touch: Supports multi touch (such as Weixue Electronics' GT911 chip solution), controlled through
I2C interface.
III. Other features and applicable scenarios
-Working temperature: Most products support -20 ℃~70 ℃, with some industrial grade models extending to
-30 ℃~85 ℃.
-Backlight and power consumption: WLED side in backlight is the main type, with a typical power consumption
of 640mW (RGB interface) to lower (MCU interface).
-Application areas: industrial instruments, automotive devices, smart homes, medical equipment, etc.
If you need a specific 4.3-inch selection, you can consult Hangzhou Xuhong, inform them of the parameter
requirements of the LCD screen, and then recommend a cost-effective 4.3-inch LCD screen for you.
