DATA SHEET MOS INTEGRATED CIRCUIT µ PD16772 480-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 64-GRAY SCALES) DESCRIPTION The µ PD16772 is a source driver for TFT-LCDs capable of dealing with displays with 64-gray scales. Data input is based on digital input configured as 6 bits by 6 dots (2 pixels), which can realize a full-color display of 260,000 colors by output of 64 values γ -corrected by an internal D/A converter and 5-by-2 external power modules. Because the output dynamic range is as large as VSS2 + 0.1 V to VDD2 – 0.1 V, level inversion operation of the LCD’s common electrode is rendered unnecessary. Also, to be able to deal with dot-line inversion, n-line inversion and column line inversion when mounted on a single side, this source driver is equipped with a built-in 6-bit D/A converter circuit whose odd output pins and even output pins respectively output gray scale voltages of differing polarity. Assuring a clock frequency of 45 MHz when driving at 2.3 V, this driver is applicable to UXGA-standard TFT-LCD panels.

PIN FUNCTIONS Pin Symbol S1 to S480 D00 to D05 D10 to D15 D20 to D25 D30 to D35 D40 to D45 D50 to D55 R,/L Shift direction control These refer to the start pulse I/O pins when driver ICs are connected in cascade. The shift input directions of the shift registers are as follows. R,/L = H: STHR input, S1 → S480, STHL output R,/L = L: STHL input, S480 → S1, STHR output Right shift start pulse These refer to the start pulse I/O pins when driver ICs are connected in cascade. Fetching of display data starts when H is read at the rising edge of CLK. input/output Left shift start pulse R,/L = H (right shift): STHR input, STHL output R,/L = L (left shift): STHL input, STHR output input/output The start pulse width (H level) for next-level drivers is 1CLK. Shift clock input Refers to the shift register’s shift clock input. The display data is incorporated into the data register at the rising edge. At the rising edge of the 80th clock after the start pulse input, the start pulse output reaches the high level, thus becoming the start pulse of the next-level driver. If 82 clock pulses are input after input of the start pulse, input of display data is halted automatically. The contents of the shift register are cleared at the STB’s rising edge. The contents of the data register are transferred to the latch circuit at the rising edge. And, at the falling edge, the gray scale voltage is supplied to the driver. It is necessary to ensure input of one pulse per horizontal period. POL = L: The S2n–1 output uses V0 to V4 as the reference supply. The S2n output uses V5 to V9 as the reference supply. POL = H: The S2n–1 output uses V5 to V9 as the reference supply. The S2n output uses V0 to V4 as the reference supply. S2n-1 indicates the odd output: and S2n indicates the even output. Input of the POL signal is allowed the setup time(tPOL-STB) with respect to STB’s rising edge. Data inversion can invert when display data is loaded. POL21/22 = H : Data inversion loads display data after inverting it. POL21/22 = L : Data inversion does not invert input data. POL21: D00 to D05, D10 to D15, D20 to D25 POL22: D30 to D35, D40 to D45, D50 to D55 The current consumption of VDD2 is lowered by controlling the constant current source of the output amplifier. This pin is pulled up to the VDD1 power supply inside the IC. For details, see 9. CURRENT CONSUMPTION REDUCTION FUNCTION. This pin can be used to finely control the bias current inside the output amplifier. When this fine-control function is not required, leave this pin open. For details, see 9. CURRENT CONSUMPTION REDUCTION FUNCTION. Input the γ -corrected power supplies from outside by using operational amplifier. Make sure to maintain the following relationships. During the gray scale voltage output, be sure to keep the gray scale level power supply at a constant level.

The power start sequence must be VDD1, logic input, and VDD2 & V0 to V9 in that order. Reverse this sequence to shut down (Simultaneous power application to VDD2 and V0 to V9 is possible.). 2. To stabilize the supply voltage, please be sure to insert a 0.1 µF bypass capacitor between VDD1-VSS1 and VDD2-VSS2. Furthermore, for increased precision of the D/A converter, insertion of a bypass capacitor of about 0.01 µF is also advised between the γ -corrected power supply terminals (V0, V1, V2,....., V9) and VSS2.

RELATIONSHIP BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE The µ PD16772 incorporates a 6-bit D/A converter whose odd output pins and even output pins output respectively gray scale voltages of differing polarity with respect to the LCD’s counter electrode (common electrode) voltage. The D/A converter consists of ladder resistors and switches. The ladder resistors (r0 to r62) are designed so that the ratio of LCD panel γ-compensated voltages to V0’ to V63’ and V0” to V63” is almost equivalent. For the 2 sets of five γ-compensated power supplies, V0 to V4 and V5 to V9, respectively, input gray scale voltages of the same polarity with respect to the common voltage. When fine gray scale voltage precision is not necessary, there is no need to connect a voltage follower circuit to the γ-compensated power supplies V1 to V3 and V6 to V8. Figure 5–1 shows the relationship between the driving voltages such as liquid-crystal driving voltages VDD2 and VSS2, common electrode potential VCOM, and γ -corrected voltages V0 to V9 and the input data. Be sure to maintain the voltage relationships of VDD2 – 0.1 V > V0 > V1 > V2 > V3 > V4 > 0.5 VDD2 > V5 > V6 > V7 > V8 > V9 > VSS2 + 0.1 V Figures 5–2 and 5–3 show the relationship between the input data and the output voltage and the resistance values of the resistor strings.

CURRENT CONSUMPTION REDUCTION FUNCTION The µ PD16772 has a low power control function (LPC) which can switch the bias current of the output amplifier between two levels and a bias control function (Bcont) which can be used to finely control the bias current. • Low Power Control Function (LPC) The bias current of the output amplifier can be switched between two levels using this pin (Bcont: Open). LPC = H or Open: Low power mode LPC = L: Normal power mode The VDD2 of static current consumption can be reduced to two thirds of that in normal mode. Input a stable DC current (VDD1/VSS1) to this pin. • Bias Current Control Function (Bcont) It is possible to fine-control the current consumption by using the bias current control function (Bcont pin). When using this function, connect this pin to the stabilized ground potential (VSS2) via an external resistor (REXT). When not using this function, leave this pin open. Figure 9–1. Bias Current Control Function (Bcont) µ PD16772 Bcont LPC REXT H/L VSS2 Refer to the table below for the percentage of current regulation when using the bias current control function. Table 9–1. Current Consumption Regulation Percentage Compared to Normal Mode REXT Current Consumption Reguration Percentage LPC = L ∞ (Open) 50 kΩ 20 kΩ 0Ω 100% 120% 140% 240% LPC = H/Open 65% 80% 100% 210% VDD1 = 3.3 V VDD2 = 8.7 V Remark The above current consumption regulation percentages are not product-characteristic guaranteed as they are based on the results of simulation. Caution Because the low-power and bias-current control functions control the bias current in the output amplifier and regulate the over-all current consumption of the driver IC, when this occurs, the characteristics of the output amplifier will simultaneously change. Therefore, when using these functions, be sure to sufficiently evaluate the picture quality. 11 Data Sheet S14416EJ1V0DS00 µPD16772 10.

Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to V DD o r GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
