China 2.8 inch touch screen ST7789 Manufacturers, Suppliers, Factory

What are the mainstream resolutions in the 3.5-inch TFT LCD screen market?

In today's consumer electronics industry, both technologies are widely used, often appearing in the same device. For example, in an ultra-thin laptop, the main connection between the motherboard and screen might use direct gold-finger connectors for the sake of thinness, while the connections between the motherboard and components like the touchpad and keyboard might use traditional connectors. If reliability and maintainability are more important than saving a fraction of a millimeter in thickness, then connectors are a more reliable and mature choice. If you are building an ultra-thin, cost-sensitive new product with a high-precision automated production line, you should carefully consider the direct gold-finger connector solution.

Many clients designing compact, slim-profile devices frequently inquire about small, elongated displays. Today, Mr. Huang—an engineer at Shenzhen Hongjia Technology—introduces a 1.47-inch bar-type display featuring a 172×320 resolution. This model supports both SPI and MCU interfaces, utilizes a 24-pin connection, includes a capacitive touch panel with an I2C interface, and is driven by the stable and reliable ST7789 IC. Below, Mr. Huang provides an analysis of why this 1.47-inch bar display is an excellent hardware choice for small-scale devices.
