Product Highlights of the 37-Pin Soldered 2.4 inch tft lcd display

• 37PIN Soldering Design, Lower Cost and Easier Assembly: Adopting 37PIN through-hole soldering pins, it can be directly soldered to connect with the main board without matching FPC connectors, DuPont wires and other accessories, which greatly reduces the accessory cost and assembly processes. At the same time, the pins are regularly arranged with high soldering fault tolerance, suitable for small and medium batch production and DIY development. Compared with plug-in models, the comprehensive assembly cost is reduced by more than 30%, which is the core advantage of the low-cost display module;
• Dual-Interface Mode, Full-Platform Hardware Compatibility: It supports MCU 8bit/16bit dual data bus mode. The 8bit mode can use DB[8-15], and the 16bit mode can use DB[0-15], which can be flexibly compatible with mainstream development platforms such as 51 MCU, STM32, ESP32, and Arduino. It is also equipped with the mature ST7789 driver chip on the market, and a wealth of driver codes and development cases can be obtained online, which lowers the development threshold and greatly shortens the product R&D cycle;
• Precise Structural Design, Suitable for Miniaturized Devices: The overall dimensional tolerance of the product is controlled within ±0.2mm, the core bonding accuracy reaches ±0.03mm, and the back thickness is only 2.50±0.2mm. The ultra-thin and high-precision structural design can effectively save internal equipment space, perfectly adapting to various miniaturized and integrated electronic devices. At the same time, the normally white display mode combined with 55% NTSC color gamut balances color reproduction and display clarity while ensuring cost;
• Low-Power Design, Suitable for Portable Devices: With a low operating voltage of 2.8~3.3V and a backlight driving current of 80mA, it effectively reduces the overall power consumption of the device and extends the battery life of portable devices. At the same time, the backlight driving conditions are standardized, and the backlight brightness can be adjusted through simple circuit design to meet the display brightness needs of different scenarios;

Technical Q&A of 2.4 inch tft lcd display 37PIN Soldering Type

Q1: What are the advantages of the ST7789 driver chip equipped in this 2.4 inch tft lcd display?

Finally, the chip has high driving stability, can support a standard resolution of 240×320, and is combined with 55% NTSC color gamut, which can ensure clear and delicate display effect, making it a classic driving solution for small-size TFT LCD.

Q2: What are the specific cost and assembly advantages of the 37PIN soldering type compared with the plug-in type 2.4 inch tft lcd display?

A2: Compared with the traditional plug-in type, the 37PIN soldering type of this product has three cost and assembly advantages:

First, lower accessory cost. The 2.4 inch tft lcd display soldering type does not need to be matched with FPC connectors, DuPont wires, connectors and other accessories, and is directly connected to the main board through pin soldering, saving the purchase cost of connectors.

Second, simpler assembly process. The 37PIN pins are regularly arranged, the soldering operation is convenient, no professional plug-in equipment is required, and both manual soldering and assembly line soldering are available, which greatly shortens the assembly time and improves production efficiency.

Third, more convenient later maintenance. The 2.4 inch tft lcd display soldering connection has higher stability, avoiding the poor contact, loosening and other problems of the plug-in type after long-term use, and reducing the later maintenance cost and failure rate of the equipment. At the same time, the structural design of the soldering type is simpler, which can effectively save internal equipment space and adapt to the design of miniaturized products.
