China 2.3 inch lcd display module IPS ILI9342C SPI/MCU Manufacturers, Suppliers, Factory

​Our company has successfully mass-produced 2.3-inch TFT horizontal screens with a resolution of 480*360 and IPS full viewing angles, filling the long-term vacancy in the 2.3-inch horizontal screen market with only low resolution and no full viewing angles.

a 7-inch screen compatible with Hitachi TX18D35VM0AAA 7-inch industrial control LCDs. It features an 800*480 resolution, RGB or LVDS interfaces, and an automotive-grade operating temperature range of -30°C to 85°C. Its dimensions are perfectly compatible with Hitachi 7-inch screens, making it a perfect replacement. This cost-effective screen offers cost savings. We welcome inquiries by email.

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.

Polarizer is one of the important materials of liquid crystal display. It is a composite material made of polyvinyl alcohol (PVA) stretched film and cellulose acetate film (TAC) through multiple lamination, stretching, coating and other processes. , can realize liquid crystal display high brightness, high contrast characteristics. Polarizers account for about 10% of the cost of TFT-LCD (Thin Film Transistor Liquid Crystal Display) panels.

If customers encounter screen display problems and want to check whether they are caused by flexible cables, they can check from the following aspects, including appearance, material, process, and functional testing to distinguish: It should be noted that the display screen may not display normally sometimes not because of the flexible cable itself, but because of interface oxidation or motherboard problems, but the flexible cable is the easiest to check as a connecting component. Therefore, when distinguishing problems, multiple factors should be considered comprehensively, and you cannot just look at one point.

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.
