2.8-inch round screen is widely used in smart home, home appliances, industrial instruments and equipment, beauty instruments and other products, true round screen display, upscale design, welcome customers to email consultation, we provide technical support, also support customized services.

The 2.8-inch LCD screen has a resolution of 240*400, a vertical 16:9 aspect ratio, and uses the ILI9327 or ST7793 driver IC. It supports SPI/MCU/RGB interfaces and is a relatively mature LCD screen on the market, suitable for customers using microcontrollers. It can significantly reduce the overall cost for customers

In short, for small-sized LCD screens, QSPI is a better choice: through pin multiplexing and queue mechanism, while maintaining sufficient transmission rate, PCB design and master control resource usage are greatly simplified, which is especially suitable for scenarios that require dynamic display and limited space. SPI is only applicable to extreme cases where the driver IC does not support QSPI or has extremely simple functions. When actually selecting, it is necessary to first confirm the interface specifications of the screen driver IC (some screens support both SPI and QSPI, which can be switched by configuring pins).

The material design of underwater touch screens must focus on the three core goals of "waterproof and water-proof, corrosion-resistant and non-failure, and touch without misjudgment". The super-hydrophobic cover layer is used to reduce water interference, corrosion-resistant conductive materials replace traditional ITO, and precision sealing structures block water penetration. In addition, the appropriate material combination is selected in combination with scene requirements (such as consumer grade/industrial grade/deep sea grade).

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

At present, our company has 3 fully automatic FOG production lines and 3 fully automatic backlight assembly lines, with a monthly production capacity of 800K. Shenzhen Hongjia Technology has 12 years of industry experience, specializing in R&D, production and sales of 1.14-inch to 15-inch display screens and matching touch screens.
