China 3.1 inch tft lcd display RGB Manufacturers, Suppliers, Factory

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.).

HJ1800-01, a 1.8-inch round LCD with IPS, full viewing angle, 360*360 resolution, and a contrast ratio of 1200. It supports multiple interfaces (SPI/MCU/QSPI/MIPI) via the IM port, and supports an ultra-wide operating temperature range of -30°C to 80°C. The driver IC is the ST77916, and standard ICs are available for a long time. This 1.8-inch round LCD features a capacitive touchscreen and I2C interface. The touchscreen is laminated to the LCD for easy debugging.

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.

How to choose between amorphous silicon (a-Si) and low temperature polysilicon (LTPS) for project development with display

In addition, when designing the touch screen circuit principle, the grounding of the FPC cable can be increased, or the touch screen cable can be covered with double-sided black electromagnetic film, which can also reduce the electromagnetic interference problem of the touch screen in practical applications. Shenzhen Hongjia Technology has been professionally developing and producing 1.14-inch to 10.1-inch displays and supporting touch screens for 12 years. It has a R&D team of more than 20 people who are familiar with solving common problems in the industry and can reduce troubles for customers.

In today's consumer electronics industry, both technologies are widely used, often appearing in the same device. For example, in an ultra-thin laptop, the main connection between the motherboard and screen might use direct gold-finger connectors for the sake of thinness, while the connections between the motherboard and components like the touchpad and keyboard might use traditional connectors. If reliability and maintainability are more important than saving a fraction of a millimeter in thickness, then connectors are a more reliable and mature choice. If you are building an ultra-thin, cost-sensitive new product with a high-precision automated production line, you should carefully consider the direct gold-finger connector solution.
