Description : 5 V Drive 240 Outputs TFT-LCD Source Driver View

5 V Drive 240 Outputs TFT-LCD Source Driver

Part Name(s) : LH1687 Sharp
Sharp Electronics
Description : 240-output TFT-LCD Source Driver IC View

DESCRIPTION
The LH1687 is a 240-output TFT-LCD Source Driver IC used in such products as TV sets. The LH1687 samples and holds three video signals of R, G and B by sample and hold circuits synchronized with the CK, and simultaneously Outputs the LCD Drive voltage from all output pins.

FEATURES
• Number of LCD Drive Outputs : 240
• Output circuit form : Push pull output

• Sampling timing : Normal sampling operation and 3-point simultaneous sampling operation can be selected
• Video signal setting : Available for stripe pixel array panels and delta pixel array panels using mode setting circuit
• Sampling clock frequency : 25 MHz (MAX.)
• Cascade connection
• Sampling sequence : Output shift direction can be selected OS1/OS240 or OS240/OS1
• Output amplitude voltage : 4.8 Vp-p (at 5.0 V supply voltage)
• Supply voltages
    — VCCL (for logic system) : +3.0 to +5.5 V
    — VCCA (for LCD Drive system) : +3.0 to +5.5 V
• Operating temperature : —30 to + 85 ßC
• Package : 264-pin TCP (Tape Carrier Package)

Part Name(s) : UPD16449 UPD16449P UPD16449N NEC
NEC => Renesas Technology
Description : Source DriveR FOR 240-OUTPUT TFT-LCD (NAVIGATION, AUTOMOBILE LCD-TV) View

DESCRIPTION
µPD16449 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
