Product Core Highlights​

Multi-Interface Compatibility, Extremely Low Development Threshold​

The 5 inch display supports four mainstream communication interfaces: MCU 8-Bit, MCU 16-Bit, SPI-3L, and SPI-4L. The data buses correspond to DB[0~15], DB[0~7], and SCLK/SDA/CS pins respectively. It can be directly connected to mainstream development platforms such as STM32, Arduino, and Raspberry Pi without additional adapter boards, greatly reducing hardware development and software transplantation costs.​

Compact Structure and Thin Design, Strong Adaptability​

The overall size of this 5 inch display is only 68.5×133mm, with a thickness of less than 5mm. The back interface layout is neat (CN1, CN2 terminals), facilitating equipment structure design and heat dissipation. The pure black panel has a simple appearance, which can be integrated into various product design styles, and can be perfectly adapted to both embedded installation and external installation.​

Wide Temperature Reliability, Adapt to Harsh Environments​

The operating temperature of this 5 inch display covers -20℃ to +70℃, and the storage temperature reaches -30℃ to +80℃, which can work stably in extreme environments such as extreme cold and high temperature, meeting the reliability requirements of industrial, automotive, outdoor and other scenarios. At the same time, the backlight drive and touch power supply adopt a unified 3.0V voltage, simplifying the power supply design and improving system stability.​

Technical Q&A​ about 5 inch display with Capacitive Touchscreen

Q1: What communication interfaces does this 5 inch display support? What are the pin definitions corresponding to different interfaces?​

A: This 5 inch display supports 4 common interfaces, which are easy to adapt, and the pin correspondence is easy to remember without complicated professional terms:​

MCU-16bit: Uses 16 data lines, corresponding to pins 19~25, 2~9, with fast data transmission speed, suitable for devices that require clear dynamic display;​
MCU-8bit: Uses 8 data lines, corresponding to pins 2~9, simple to operate, suitable for ordinary devices with simple functions;​
SPI-3L: Uses only 3 lines (corresponding to pins 11, 12, 10), energy-saving, with sufficient transmission distance, very suitable for daily use;​
SPI-4L: Adds 1 more line (corresponding to pin 15) on the basis of 3 lines, with more stable data transmission and less error.​

Q2: How is the touch function of the 5 inch display realized? What is the model of the touch chip?​

A: This 5 inch display integrates capacitive touch function, the touch driver chip is GT911, the touch interface is IIC protocol, corresponding to pins TP-SDA (12), TP-SCLK (11), TP-INT (14), TP-RST (9). Through IIC communication, it can realize multi-touch detection, support precise click, slide and other operations, with fast touch response speed, suitable for interactive devices.​

Q3: What are the backlight drive parameters of this 5 inch display? How to design the backlight circuit?​

A: The backlight drive conditions of this 5 inch display are Vf=18.0±1.0V, If=40mA, that is, the forward voltage of the backlight LED is about 18V, and the working current is 40mA. When designing the backlight circuit, a constant current drive scheme should be adopted to ensure that the current is stably around 40mA, avoiding LED burnout or shortened service life due to excessive current. At the same time, the backlight brightness can be adjusted through PWM signal to achieve a balance between energy saving and display effect.​
