China 3.0 inch touch screen 320*480 RGB/SPI Manufacturers, Suppliers, Factory

2.2-inch LCD screens for a long time, maintaining a safe inventory to ensure continuous supply. This 2.2-inch LCD display has a resolution of 240*320, uses the mature ST7789 IC, offers high reliability, and supports SPI/MCU/RGB interfaces, including 3/4-wire SPI interfaces, 8-bit/16-bit MCU interfaces, and 16/18/24-bit RGB interfaces. The 2.2-inch TFT screen is positioned between 2.4-inch and 2.8-inch LCD screens, suitable for customers requiring a small size, and also supports microcontrollers. It has been favored by many customers. We also provide customized services, including flexible cable interfaces, backlight brightness, and touch screens.

After VGA, QVGA, WVGA, and HVGA resolution products were gradually born. These resolutions can be seen everywhere in the mobile phone parameters. The following is the explanation and difference of VGA, QVGA, WVGA, and HVGA.

In the design of small and medium-sized LCD panels, hardware engineers often encounter difficulties in understanding the differences between VCC, VDD, and IOVCC

Shenzhen Hongjia Technology has launched a 3.0-inch IPS display for the handheld small game console market. It has a resolution of 320*480 high-definition and delicate, 4:3 structure, horizontal display, and ultra-narrow frame; it uses high-brightness and low-power LED lights, which are clearly readable in outdoor sunlight, and the brightness can reach 1000 lumens; it supports 16/18/24BIT RGB interface and 39PIN standard interface.

Our company has developed a 4.3-inch vertical screen and has been mass-produced. The display supports MCU interface 8BIT and 16BIT. The screen driver IC has video memory, which can realize the flip display of the screen.

Many customers have reported that touchscreens easily separate from the casing in extremely cold or hot environments. This is usually due to the use of ordinary double-sided tape to fix the touchscreen. Shenzhen Hongjia Technology engineers, through extensive research, have found that using VHB double-sided tape around the edges of the touchscreen cover glass solves this problem of screen separation from the casing. In the assembly of high-end touchscreens (especially for demanding industrial, automotive, outdoor, and high-end consumer electronics products), using 3M VHB double-sided tape to fix the cover glass has become a "gold standard" process. Its advantages far outweigh traditional liquid adhesives or ordinary double-sided tapes.
