| DATA SHEET MOS INTEGRATED CIRCUIT PD16449 SOURCE DRIVER FOR 240-OUTPUT TFT-LCD (NAVIGATION, AUTOMOBILE LCD-TV) DESCRIPTION PD16449 is a source driver for TFT liquid crystal panels. This IC consists of a multiplexer circuit supporting a variety of pixel arrays, a shift register that generates sampling timing, and two sample and hold circuits that sample analog voltages. Because the two sample and hold circuits alternately execute sampling and holding, a high definition can be obtained. In addition, simultaneous sampling and successive sampling are automatically selected according to the pixel array of the LCD panel. It is ideal for a wide range of applications, including navigation systems and automobile LCD-TVs. FEATURES * Can be driven on 5 V (Dynamic range: 4.3 V, VDD2 = 5.0 V) * 240-output * fCLK = 15 MHz MAX. (VDD1 = 3.0 V) * Simultaneous/successive sampling selectable according to pixel array Simultaneous sampling: Vertical stripe Successive sampling: Delta array, mosaic array * Two sample and hold circuits * Low output deviation between pins ( 20 mV MAX.) * Stripe, delta, and mosaic pixel arrays supported by internal multiplexer circuit * Left and right shift selected by R,/L pin * TCP/COG mounting possible 5 Remark /xxx indicates active low signal. 5 ORDERING INFORMATION Part Number Package TCP Chip PD16449N-xxx PD16449P Remark Purchasing the above chip entails the exchange of documents such as a separate memorandum or product quality, so please contact one of our sales representative.

Output sampled and held video signals during horizontal period. Start pulse I/O pins of sample hold timing. STHR serves as an input pin and STHL, as an output pin, in the case of right shift. In the case of left shift, STHL serves as an input pin, and STHR, as an output pin. A start pulse is read at the rising edge of CLI1. Sampling pulse SHPn is generated at the rising edge of CLI1 through CLI3 during successive sampling, and at the rising edge of CLI1 during simultaneous sampling (for details, refer to the Timing charts in 5. FUNCTIONAL DESCRIPTION). INH RESET Inhibit input Reset input 31 to 33 28 to 30 Input Input Selects a multiplexer and one of the two sample and hold circuits at the falling edge. Resets the select counter of the multiplexer and the selector circuit of the two sample and hold circuits when it goes high. After reset, the multiplexer is turned OFF, so sure to input one pulse of the INH signal before inputting the video signal. If the video signal is input without the INH signal, sampling is not executed.

FUNCTIONAL DISCRIPTION 5.1 Multiplexer Circuit This circuit selects RGB video signals input to the C1 to C3 pins according to the pixel array of the liquid crystal panel, and outputs the signals to the H1 through H240 pins. Vertical stripe array, single-/double-side delta array, or mosaic array can be selected by using the MP/TH and MP/1.5 pins. 5.1.1 Vertical stripe array mode (MP/TH = L, MP/1.5 = L) In this mode, the relation between video signals C1 to C3, and output pins is as shown below. This mode is used to drive a panel of vertical stripe array. In this mode, the multiplexer circuit is in the through status. Table 5-1.

Swa1 through Swb2 are reset by the RESET signal and change at the rising and falling edges of the INH signal (refer to 1. BLOCK DIAGRAM.). RESET Data undifined INH Swa1 Swa2 Swb1 Swb2 undifined ON ON 5.3 Write Operation Timing The sampled video signals are written to the LCD panel by output currents IVOL and IVOH via output buffer. The dynamic range is 4.3 V MIN. (VDD2 = 5.0 V). While INH = H, do not stop shift clocks CLI1 through CLI3. The output operation of this IC is controlled by INH signals. INH = Hi-Z INH = Connected with internal circuit (switch sample and hold circuit at the falling edge.) Therefore, performing VCOM inversion while INH = L causes current flow to these IC output pins, which may result in malfunction. Perform VCOM in version during INH = H (Hi-Z) and start output operation of the next line after the VCOM signal is stable enough to operate. Make sure to evaluate this output operation sufficiently. Data Sheet S15677EJ1V0DS 17 PD16449 Cautions 1. Turn on power to VDD1, logic input, VDD2, and video signal input in that order to prevent destruction due to latch-up, and turn off power in the reverse sequence. Observe this power sequence even during the transition period. 2. The PD16449 is designed to input successive signals such as chrome signals. The input band of the video signals is designed to be 9 MHz MAX. If video signals faster than that are input, display is not performed correctly. 3. Insert a bypass capacitor of 0.1 F between VDD1 and VSS1 and between VDD2 and VSS2. If the power supply is not reinforced, the sampling voltage may be abnormal if the supply voltage fluctuates. 4. 5. 6. Display may not be correctly performed if noise is superimposed on the start pulse pin. Therefore, be sure to input a reset signal during the vertical blanking period. Even if the start pulse width is extended by half a clock or more, sampling start timing SHP1 is not affected, and the sampling operation is performed normally. When the multiplexer circuit is used in the vertical stripe mode, C1 to C3 are simultaneously sampled at the rising edge of SHPn. Internally, however, only CLI1 is valid. Therefore, input a shift clock to CLI1 only. At this time, keep the CLI2 and CLI3 pins to "L". When using the multiplexer circuit in the delta array mode or mosaic array mode, C1 to C3 are sequentially sampled. Input a three-phase clock to CLI1 through CLI3 (for the sampling timing, refer to 5. FUNCTIONAL DESCRIPTION.). 7. The recommended timing of tR-1 and PWRES on starting is shown below (The following timing chart shows simultaneous sampling.). An INH pulse width of at least 5 clocks is required to reset the internal logic. Unless the INH pulse is input after reset, sampling is not performed in the correct sequence.

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 VDD or 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. Data Sheet S15677EJ1V0DS 27 |
