China 3.5 inch Capacitive touch display module 320*480 Manufacturers, Suppliers, Factory

Backlighting is used in small, light, flat-panel liquid crystal displays (LCDs) and other electronic devices that require backlighting, including handheld devices as small as the palm of your hand, and large-screen TVs. The goals of backlight design include low power consumption, ultra-thin, high brightness, uniform brightness, large area, and control of different width and narrow viewing angles. To achieve these challenging design goals with controlled cost and rapid implementation, computer-aided optical design tools must be used for design. This article introduces the characteristics of LightTools optical design and analysis software from ORA Company in the United States, which can be used to develop the most advanced backlight design applications today.

The HJ2101-02 is a 2.1-inch round LCD with a MIPI interface, supporting a variety of resolutions, including 540*540, 480*480, and 360*360. Compared to the 480*480 2.1-inch round screens on the market, it offers higher-definition, finer-grained displays with more vivid and lifelike colors.

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).

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.
