HD66113T (120-Channel Common Driver Packaged in a Slim Tape Carrier Package) Description The HD66113T is a common driver for large dot matrix liquid crystal graphics displays. It features 120 channels which can be divided into two groups of 60 channels by selecting data input/output pins. The driver is powered by about 3V, making it suitable for the design of portable equipment which fully utilizes the low power dissipation of liquid crystal elements. The HD66113T, packaged in a slim tape carrier package (slim-TCP), makes it possible to reduce the size of the user area (wiring area).

VLCD, GND: Supply power to the LCD drive circuits (Figure 1). V1L, V1R, V2L, V2R, V5L, V5R, V6L, V6R: Supply different power levels to drive the LCD. V1 and V2 are selected levels, and V5 and V6 are non-selected levels. Control Signals CL: Inputs data shift clock pulses for the shift register. At the falling edge of each CL pulse, the shift register shifts data input via the DIO pins. M: Changes the LCD drive outputs to AC. CH: Selects the data shift mode. (CH = high: 2 x 60-output mode, CH = low: 120-output mode) SHL: Selects the data shift direction for the shift register and the common signal scan direction (Figure 2). DIO1, DIO2: Input or output data. DIO1 is input and DIO2 is output when SHL is high. DIO1 is output and DIO2 is input when SHL is low. DI: Input data. DI is input to X61-X120 when CH and SHL are high, and to X60-X1 when SHL is low. DISPOFF: Controls LCD output level. A low DISPOFF sets the LCD drive outputs X1-X120 to the V2 level. A high DISPOFF is normally used. LCD Drive Outputs X1-X120: Each X outputs one of four voltage levels V1, V2, V5, or V6, depending on the combination of the M signal and the data level (Figure 3). 4 HD66113T VLCD1, 2 VCC GND Figure 1 Power Supply for LCD Driver SHL Data shift direction High Shift to right DIO1 SR1 SR2 SR3 * * * SR120 DIO2 Low Shift to left DIO2 SR120 SR119 * * * SR1 DIO1 Note: SR1 to SR120 correspond to the outputs of X1 to X120, respectively.

One of these four levels is output to the corresponding X pin, depending on the combination of the M signal and the data in the shift register. Level Shifter The level shifter changes logic control signals (2.5 V-5.5 V) into high-voltage signals for the LCD drive circuit. Shift Register The 120-bit shift register shifts the data input via the DIO pin by one bit at a time. The one bit of shiftedout data is output from the DIO pin to the next driver IC. Both actions occur simultaneously at the falling edge of each shift clock (CL) pulse. The SHL pin selects the data shift direction. 7 HD66113T Absolute Maximum Ratings Item Power supply voltage for logic circuits Power supply voltage for LCD drive circuits Input voltage 1 Input voltage 2 Input voltage 3 Operating temperature Storage temperature Notes: 1. 2. 3. 4. 5.

Indicates the resistance between one of the pins X1-X120 and one of the voltage supply pins V1, V2, V5, or V6, when load current is applied to the X pin; defined under the following conditions: VLCD-GND = 40V V1, V6 = VCC - {1/20 (VLCD-GND)} V5, V2 = GND + {1/20 (VLCD-GND)} All voltages must be within V, VLCD V1 V6 VLCD - 7.0V, and 7.0V V5 V2 GND. Note that V depends on the power supply voltage VLCD-GND (Figure 5). 2. Input and output currents are excluded. When a CMOS input is left floating, excess current flows from the power supply through the input circuit. To avoid this, VIH and VIL must be held at VCC and GND, respectively.

Figures 10 and 11 show examples of how HD66113Ts can be configured to drive a 240-line LCD panel with a 1/240 duty cycle. The HD66113T's 120 channels can be divided into two groups of 60 channels, and its data shift direction can be changed by selecting the data output mode pin (CH) and data shift pin (SHL), respectively.

At this time, input 0 to the DISP pin. (2) Display-off function forces the LCD driver to output a V2 level (lowest level). (3) Display-off function takes priority even if the input signal status becomes irregular immediately after VCC power-on. (4) Input the specified signals to initialize registers of the LCD driver. Its period must be 1 frame or longer. (5) Set the DISP level to 1 to cancel display-off function after steps (1) to (4). At this time, VLCD and each V pin input must be at the specified levels. 18 HD66113T At Power Off Basically, the power-off procedure is the reverse of the power-on procedure. (1) Set the DISP level to 0. (2) Lower LCD driver power supply to 0V (3) Lower VCC and each input signals to 0V At this time, each V pin input must be at 0V. Display-off function stops when V CC falls to 0V, and therefore, the LCD driver may output a level other than V2 (lowest level). As a result, a display error may be caused at power-off or power-on. 19 HD66113T LCD Driver LSI Power Supply Pin Connection A feature of the LCD driver is the LCD drive power supply. As the number of pixel drives per LSI increases, so does the voltage and number of outputs. Consequently, if multi-output CMOS circuits are switched simultaneously, a wiring voltage drop may occurs due to transient currents, and the potential between the LCD drive circuit power supply (VLCD) and LCD drive level power supplies (V1, V6, and V3) or GND and the LCD level power supplies (V2, V5, and V4) may be inverted, resulting in latchup breakdown. To prevent this, it is recommended that, when designing the LCD drive power supply and board power supply wiring, the power supply wiring be designed as low-impedance and capacitors be inserted in the wiring between VLCD and V1, V3, V6, and between V2, V4, V5 and GND. In set evaluation, it is recommended that a check be carried out to confirm that there is no inversion of the LCD drive power supply and level power supplies in the period between when the LCD drive power supply is turned on and turned off.
