China 3.2 inch lcd display 240*320 14PIN SPI Manufacturers, Suppliers, Factory

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.

In the specifications of small and medium-sized color LCD screens, you often see "always white" and "always black" display modes. What do these specifically mean? Engineers from Shenzhen Hongjia Technology explain here. Always white and always black are two basic operating modes of an LCD monitor

In order to meet the stringent environmental temperature requirements of different customers and different product applications, our company has launched a variety of ultra-low temperature LCD screens. The operating temperature can reach -30 to 85 degrees, and the storage temperature is also -30 to 85 degrees. The wide-temperature LCD screen has picture It has the characteristics of stable quality and adaptability to harsh environmental temperatures, and can be widely used in military, telecommunications, electric power, metallurgy, machinery, CNC, petroleum, chemical industry, medical, aerospace and other fields.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

See why a 4.3-inch 480×800 IPS RGB display suits portrait embedded interfaces, plus integration checks that prevent costly redesigns early in production.
