6 BIT 480 CHANNEL TFT-LCD SOURCE DRIVER
INTRODUCTION
The S6C0676 is a 480 channel output, TFT LCD source driver for 64 gray scale displays. Data input is based on digital input consisting of 6 bits by 6 dots, which can realize a full-color display of 260,000 colors by output of 64 values gamma-corrected. This device has an internal D/A (Digital-to-Analog) converter for each output and 10 (5-by-2) external power supplies. Because the output dynamic range is as large as 4.8 - 7.8 Vp-p, it is unnecessary to operate level inversion of the LCD's common electrode. Besides, to be able to deal with dot-line inversion when mounted on a single-side, output gray scale voltages with different polarity can be output to the odd number output pins and the even number output pins. S6C0676 can be adopted to larger panel, and SHL (shift direction selection) pin makes use of the LCD panel connection convenient. Maximum operation clock frequency is 65 MHz at a 2.7 V logic operation. it can be applied to the TFT-LCD panel of SXGA/UXGA standards.

Symbol VDD1 VDD2 VSS1 VSS2 Y1 to Y480 D0<0:5> - D5<0:5> Pin Name Logic power supply Driver power supply Logic ground Driver ground Driver outputs Display data input 2.7 - 3.6 V 5.0 - 8.0 V Ground (0 V) Ground (0 V) The D/A converted 64 gray-scale analog voltage is output. The display data is input with a width of 36 bits, gray-scale data (6 bits) by 6 dots (R,G,B) DX0: LSB, DX5: MSB This pin controls the direction of shift register in cascade connection. The shift direction of the shift registers is as follows. SHL = H: DIO1 input, Y1 Y480, DIO2 output SHL = L: DIO2 input, Y480 Y1, DIO1 output SHL = H: Used as the start pulse input pin. SHL = L: Used as the start pulse output pin. SHL = H: Used as the start pulse output pin. SHL = L: Used as the start pulse input pin. DATPOL1, 2 = L: Display data is not inverted DATPOL1 = H: Display data of D0<0:5> - D2<0:5> is inverted DATPOL2 = H: Display data of D3<0:5> - D5<0:5> is inverted POL = H: The reference voltage for odd number outputs are VGMA1 - VGMA5 and those for even number outputs are VGMA6 - VGMA10. POL = L: The reference voltage for odd number outputs are VGMA6 - VGMA10 and those for even number outputs are VGMA1 - VGMA5. Refer to the shift register's shift clock input. The display data is loaded to the data register at the rising edge of CLK2. Latches the contents of the data register at rising edge and transfers them to the D/A converter. Also, after CLK1 input, clears the internal shift register contents. After 1 pulse input on start, operates normally. CLK1 input timing refers to the "Relationships between CLK1 start pulse (DIO1, DIO2) and blanking period" of the switching characteristic waveform. Outputs the G/S data at falling edge. Description

OPERATION DESCRIPTION
DISPLAY DATA TRANSFER
When DIO1 (or DIO2) pulse is loaded into internal latch on the rising edge of CLK2, DIO1 (or DIO2) pulse enables the operation of data transfer, so data-display is valid on the next rising edge of CLK2. Once all the data of 480 channels are loaded into internal latch, it goes into stand-by state automatically, and any new data is not accepted even though CLK2 is provided until next DIO1 (or DIO2) input. When next DIO1 (or DIO2) is provided, new data-display is valid on the 2nd rising edge of CLK2 after the rising edge of DIO1 (or DIO2).
EXTENSION OF OUTPUT
Output pin can be adjusted for an extended screen by cascade connection. (1) SHL = "L" Connect DIO1 pin of previous stage to the DIO2 pin of next stage and all the input pins except DIO1 and DIO2 are connected together in each device. (2) SHL = "H" Connect DIO2 pin of previous stage to the DIO1 pin of next stage and all the input pins except DIO2 and DIO1 are connected together in each device.
RELATIONSHIP BETWEEN INPUT DATA VALUE AND OUTPUT VOLTAGE
The LCD drive output voltages are determined by the input data and 10 (5 by 2) gamma corrected power supplies (VGMA1 - VGMA10). Besides, to be able to deal with dot line inversion when mounted on a singleside, gradation voltages with different polarity can be output to the odd number output pins and the even number output pins. Among 5-by-2 gamma corrected voltages, 5 input gray-scale voltages have the same polarity with respect to the common voltage, VGMA1 - VGMA5 and VGMA6 - VGMA10 respectively.
