No part of this document may be reproduced or transmitted in any form or by any means, electronic or mechanical, for any purpose, without the express written permission of LCD Driver IC Team. Precautions for Light Light has characteristics to move electrons in the integrated circuitry of semiconductors, therefore may change the characteristics of semiconductor devices when irradiated with light. Consequently, the users of the packages which may expose chips to external light such as COB, COG, TCP and COF must consider effective methods to block out light from reaching the IC on all parts of the surface area, the top, bottom and the sides of the chip. Follow the precautions below when using the products. 1. Consider and verify the protection of penetrating light to the IC at substrate (board or glass) or product design stage. 2. Always test and inspect products under the environment with no penetration of light.

Name Clock control Function Generates latch clock (LCK), shift clock (SCK) and control clock timing according to the input of CL1, CL2 and control inputs (CS, AMS). In common driver application mode, this block generates the shift clock (LCK) for the common data Bi-directional shift register. Determines the direction of segment data shift, and input data of each Bi-directional shift register. In 4-bit segment data parallel transfer mode, data is shifted by a 4-bit unit. In common driver application mode, data is transferred to the common data shift register directly, which disables this block. Controls the clock enable state of the current driver according to the input value of enable pin (ELB or ERB). If enable input value is "Low", every clock of the current driver is enabled and the clock control block works. But if enable input is "High", current driver is disabled and the input data value has no effect on the output level. So power consumption can be lowered. Controls the output voltage level according to the input control pin (M and DISPOFFB) (refer to PIN DESCRIPTION). Stores output data value by shifting the input values. In 1-bit serial interface mode application, all 80 shift clocks (SCK) are needed to store all the display data. But in 4-bit parallel transfer mode application, only 20 clocks are needed. In common driver application mode, this block does not work. In segment driver application mode, the data from the 20x4-bit segment data shift register are latched for segment driver output. In single-type common driver application,1-bit input data (from DL or DR pin) is shifted and latched by the direction according to the SHL signal input. In dual-type common application mode, 80-bit registers are divided by two blocks and controlled independently (refer to NOTE 3). Voltage level shifter block for high voltage part. The inputs of this block are of logical voltage level and the outputs of this block are at high voltage level value. These values are input in to the driver. Selects the output voltage level according to M and latched data value. If the data value is "High" the driver output is at selected voltage level (V0 or V5), and in the reverse case the driver output value is at the non-selected level (V12 or V43). In segment driver application mode, non-selected output value is V2 or V3. and when in common driver application, this value becomes V1 or V4. COM/SEG COM/SEG

PIN DESCRIPTION
Pin V0, V12, V43, V5 SC1 - SC80 I/O I Name LCD driver output voltage level LCD driver output Function Bias supply voltage input to drive the LCD. Bias voltage divided by the resistance is usually used as a supply voltage source (refer to NOTE 2). Display data output pin which corresponds to the respective latch contents. One of V0, V12, V34 and V5 is selected as a display driving voltage source according to the combination of the latched data level and M signal (refer to NOTE 1). Clock pulse input for the bi-directional shift register. In segment driver application mode, the data is shifted to 20 x 4-bit segment data shift. The clock pulse, which was input when the enable bit (ELB/ERB) is in not active condition, is invalid. In common driver application mode, the data is shifted to 80-bit common data bi-directional shift register by the CL1 clock. Hence, this clock pin is not used (Open or connect this pin to VDD).

Control input pin to fix the driver output (SC1~SC80) to V0 level, during "Low" value input. LCD becomes non-selected by V0 level output from every output of segment drivers and every output of common drivers. When CS = "Low", S6B0086 is used as an 80-bit segment driver. When CS = "High", S6B0086 is set to an 80-bit common driver According to the input value of the AMS and the CS pin, application mode of S6B0086 is differs as shown below.

PIN DESCRIPTION (CONTINUED)
Pin D1_SID, D2_DL, D3_DM, D4_DR I/O I/O Name Display data input/serial input data/left, right data input output Function In segment driver application mode, these pins are used as 4-bit data input pin (when 4-bit parallel interface mode : AMS = "Low"), or D1_SID is used as serial data input pin and other pins are not used (connect these to VDD) (when 1-bit serial interface mode : AMS = "High"). In common driver application mode, the data is shifted from D2_DL(D4_DR) to D4_DR(D2_DL), when in single type interface mode (AMS = "Low"). In dual-type application case, the data are shifted from D2_DL and D3_DM (D4_DR and D3_DM) to D4_DR(D2_DL). In each case the direction of the data shift and the connection of data pins are determined by SHL input (refer to NOTE 3, NOTE 4). SHL Input Shift direction control Enable data input/output When SHL = "Low", data is shifted from left to right. When SHL = "High", the direction is reversed. (refer to NOTE3) In segment driver application mode, the internal operation is enabled only when enable input (ELB or ERB) is "Low" (power down function). When several drivers are serially connected, the enable state of each driver is shifted according to the SHL input. Connect these pins as below.

*Precautions for Light
Light has characteristics to move electrons in the integrated circuitry of semiconductors, therefore may change the characteristics of sem iconductor devices when irradiated with light. Consequently, the users of the packages which may expose chips to external light such as COB, COG, TCP and COF must consider effective methods to block out light from reaching the IC on all parts as the surfac e area, the top, bottom and the sides of the chip. Follow the precautions below when using the products. 1. Consider and verify the protection of penetrating light to the IC at substrate (board or glass) or product design stage. 2. Always test and inspect products under the environment with no penetration of light.
