供应LGDP4522/4524/4531/4532驱动IC

Features
● A one-chip controller driver incorporating a gate circuit and a power supply circuit for 240RGB
x320 dots graphics display on an amorphous TFT panel in 262k colors
● System interface
– High-speed interfaces via 8-, 9-, 16-, 18-bit parallel ports
– Serial interface
● Interface for moving picture display
– 6-, 16-, 18-bit bus RGB interfaces (VSYNC, HSYNC, DOTCLK, ENABLE, DB17-0)
– VSYNC interface (System interface + VSYNC)
– FMARK interface (System interface + FMARK)
● Window address function to specify a rectangular area on the internal RAM to write data
● Writes data within a rectangular area on the internal RAM via moving picture interface
– Reduces data transfer by specifying the area on the RAM to rewrite data
– Enables displaying the data in the still picture RAM area with a moving picture
simultaneously
– Resizing function (x 1/2, x 1/4)
● Abundant color display and drawing functi***
– Programmable γ -correction function for 262k-color display
– RGB independent control
– Partial display function
● Low -power c***umption architecture (allowing direct input of interface I/O power supply)
– Standby, Deep standby, sleep function
– 8-color display function
– Input power supply voltages: Vcc = 2.5V ~ 3.3 V (logic regulator power supply)
IOVcc = 1.65V ~ 3.3 V (interface I/O power supply)
Vci = 2.5V ~ 3.3 V (liquid crystal analog circuit power
supply)
● Incorporates a liquid crystal drive power supply circuit
– Source driver liquid crystal drive/Vcom power supply: DDVDH-GND = 4.5V ~ 6.0 V
– Gate drive power supply: VGH-GND = 10.0V ~ 15.0 V
VGL-GND = -4.5V ~ -12.5V
VGH-VGL ≤ 25V
● Liquid crystal power supply startup sequence
● TFT storage capacitance: Cst only (common Vcom formula)
● 172,800-byte internal RAM
● Internal 720-channel source driver and 320-channel gate driver
● Configures a COG module with one chip by arranging gate lines on both sides
