Overview
ST Sitronix 1.
Introduction 2.
Features ST7787 262K Color Single-Chip TFT Controller/Driver 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.
Single chip TFT-LCD controller/driver with display data RAM Display resolution: 240(H) x RGB x 320(V) Display data RAM (frame memory): 240 x 320 x 18-bits = 1,382,400 bits Operation Frequency: DC~30MHz (30MHz for 6 bits, 10MHz for 18 bits) Output: - 240ch source outputs (240RGB) - 320ch gate outputs - Common electrode output Display mode (color mode) - Full color mode (idle mode off): 262K-colors - Reduce color mode (idle mode on): 8-colors (1-bit for individual R, G, B color depth) Display resolution option - 240 x 320 Display with 240 x 18-bits x 320 display RAM Supported LC type option - MVA LC type (When LCM[1]=0,LCM[0]=0 ) - Transflective LC type (When LCM[1]=0,LCM[0]=1 ) - Transmissive LC type (When LCM[1]=1,LCM[0]=0 ) Supported data format on display host interface - 12-bits/pixel: RGB= (444) using the 1382k bits frame memory and LUT - 16-bits/pixel: RGB= (565) using the 1382k bits frame memory and LUT - 18-bits/pixel: RGB= (666) using the 1382k bits frame memory Supported MCU Interface - 3-line serial interface - 8-bits, 9-bits, 16-bits, 18-bits interface with 8080-series MCU - 8-bits, 9-bits, 16-bits, 18-bits interface with 6800-series MCU - 6-bits, 16-bits, 18-bits RGB interface with graphic ...
