  • 1.47-inch Bar-Type Display: 172×320 Resolution, SPI/MCU Interface Support—An Ideal Choice for Small and Portable Devices

    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.

  • How to avoid poor welding of LCD screen cables and backlight cables

    LCD and backlight cables require soldering for proper display. Traditionally, factory workers solder these cables manually. Manual soldering is slow and highly dependent on the worker's soldering proficiency. Unskilled workers can sometimes cause cold soldering, leading to sporadic soldering defects when shipped to customers, causing the display to malfunction.

  • 2.8-inch LCD Screen Resolution Upgrade: 480*640 is a major advancement in hardware design

    The typical resolution of a 2.8-inch LCD screen is 240*320 or 240*400. Because its size is larger than a 2.4-inch LCD screen, but the resolution is the same, the larger area results in less detailed display, which is why many hardware engineers don't like using it. Shenzhen Hongjia Technology engineers recommend a 2.8-inch TFT screen with IPS full viewing angle and a resolution of 480*640, offering high-definition and fine detail, compensating for the low resolution of typical 2.8-inch screens. This article will also introduce the advantages of this display and the significant changes it brings.

  • Why does the RGB interface of a small LCD screen require initialization code via SPI?

    Generally speaking, the main reasons may include: reducing the number of pins to accommodate a small package size; reducing the need for host control resources (GPIO, parallel interface); simplifying hardware design (PCB layout, level conversion); the small amount of initial configuration data, which is sufficient and easy to implement with SPI; and the driver IC design supporting serial interface configuration.

  • How to prevent the LCD screen backlight from turning yellow

    To avoid the problem of yellowing of the backlight material of the TFT LCD screen, it is necessary to start from many aspects such as material characteristics, usage environment, and driving method. In particular, it is necessary to pay attention to the selection and maintenance of the core components of the backlight module (such as LED lamp beads, light guide plates, diffusion films, etc.).

  • Causes and Solutions for Liquid Leakage in Small and Medium-Sized LCD Screens

    LCD screen leakage typically refers to the leakage of liquid/gel-like substances such as liquid crystal material or sealant from within the screen due to external forces or inherent material defects. Common symptoms include abnormal patches (such as black spots, white spots, or lines) or localized malfunctions in the display area. Lightly pressing the edge of the screen can cause a sensation of liquid flowing, which is common in LCD (liquid crystal display) screens
