LCD Driver datasheet The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power consumption.

ST7787 芯片的SPEC，比亚迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and 320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
