JCR70HD is a true color (TFT) liquid crystal display controller with built-in DRAM. It can be used with 8-bit single-chip microcomputers or more than one microcomputer to form a liquid crystal display driving control system. JCR70HD has the following features. 1. It has parallel and serial interfaces. The parallel mode displays fast, the single pixel write cycle can reach 160ns. The serial mode only needs 3 control lines, saving single-chip microcomputer resources 2. Automatically identify the color type. When editing a single pixel, receiving one byte of color data can display 256 colors. If 2 bytes of color data are received, 65535 colors can be displayed. Flexible and convenient application. JCR70HD is suitable for use in military, industrial control, medical equipment, communication, etc. industries, as a human-computer interaction interface.
