LH168K

LH168K LH168K DESCRIPTION The LH168K is a 324-output TFT-LCD source driver IC which can simultaneously display 262 144 colors in 64 gray scales. 324-output TFT-LCD Source Driver IC PIN CONNECTIONS 395-PIN TCP XO1 1 YO1 2 ZO1 3 TOP VIEW FEATURES Selectable number of LCD drive outputs : 324/321/312/309 Built-in 6-bit digital input DAC Dot-inversion drive : Outputs the inverted gray scale voltages between LCD drive pins next to each other 2-port input for each circuit of data inputs R, G and B, and it is possible to sample and hold display data of two pixels at the same time at 324-output and 312-output modes. 1-port input for each circuit of data inputs R, G and B at 321output and 309-output modes. Possible to display 262 144 colors in 64 gray scales with reference voltage input of 18 gray scales : This reference voltage input corresponds to ‹ correction and intermediate reference voltage input can be abbreviated Cascade connection Sampling sequence : Output shift direction can be selected XO1, YO1, ZO1/XO108, YO108, ZO108 or ZO108, YO108, XO108/ZO1, YO1, XO1 Shift clock frequency : 55 MHz (MAX.) Supply voltages – VCC (for logic system) : +2.7 to +3.6 V – VLS (for LCD drive system) : +12 V (MAX.) Package : 395-pin TCP (Tape Carrier Package) 395 394 393 392 391 390 GND VLS GND MODE PBS XB5 385 XB0 384 XA5 379 XA0 378 YA5 373 372 371 370 369 368 367 366 365 364 363 362 361 360 359 358 357 356 355 354 353 352 351 350 349 348 347 346 YA0 SPOI VH0 VH8 VH16 V...
