This article serves as a detailed reference guide for the HX8872C, consolidating the most critical information found in the official datasheet into an easy-to-read format. Always refer to the official Himax Technologies datasheet for absolute electrical characteristics and timing diagrams. This guide is for informational and preparatory purposes. What is the HX8872C? The HX8872C is a single-chip TFT-LCD (Thin-Film Transistor Liquid Crystal Display) controller and driver. Manufactured by Himax Technologies , this IC is designed to drive displays with a resolution of up to 240 RGB x 320 pixels (a common quarter VGA or QVGA format).
| Driver IC | Resolution | Interface | On-chip GRAM | Key Difference | | :--- | :--- | :--- | :--- | :--- | | | 240x320 | 8/16/18-bit + SPI | Yes | Mature, stable, good for QVGA | | ILI9341 | 240x320 | 4-line SPI + 8080 | Yes | More common in hobbyist community | | ST7789 | 240x320 | SPI only | Yes | Lower pin count, smaller package | | SSD1963 | Up to 800x480 | RGB parallel | No | Requires external frame buffer | hx8872c datasheet
