LCD TV Handling Precautions

1. Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when inserting or disconnecting from input connector.
(3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth

when handling.
(7) Do not open nor modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module to any directions.
(9) In case if a Module has to be put back into the packing container slot after on ce it was taken

out from the container, do not press the center of the CCFL Reflector edge. Instead, press at

the far ends of the CFL Reflector edge softly. Otherwise the TFT Module may be damaged.
(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the

Interface Connector of the TFT Module.
(11) After installation of the TFT Module into an enclosure (LCD TV housing, for example), do

not twist nor bend the TFT Module even momentary. At designing the enclosure, it should be

taken into consideration that no bending/twisting forces are applied to the TFT Module from

outside. Otherwise the TFT Module may be damaged.
(12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow

local ordinances or regulations for disposal.
(13) Small amount of materials having no flammability grade is used in the LCD module. The

LCD module should be supplied by power complied with requirements of Limited Power

Source (IEC60950 or UL1950), or be applied exemption.
(14) The LCD module is designed so that the CFL in it is supplied by Limited Current Circuit

(IEC60950 or UL1950). Do not connect the CFL in Hazardous Voltage Circuit.

2. Handling and Placing Methods

Correct Methods: Incorrect Methods:

Only touch the metal frame of the LCD panel
or the front cover of the LCD TV. Do not touch
the surface of the polarizer.

11. Working

A. A/D converter (PC & YPbPr) and DVI(HDCP) input

The MST5151LA offers designers the flexibility of an analog interface and High-Definition
Multimedia Interface (DVI) receiver integrated on a single chip. Also included is support for High
bandwidth Digital Content Protection (HDCP).

Analog Interface

The MST5151LA is a complete 8-bit 165 MSPS monolithic analog interface optimized for
capturing Component Video (YPbPr) and RGB graphics signals. Its 165 MSPS encode rate
capability and full power analog bandwidth of 300 MHz supports all HDTV formats (up to 1080p)
and FPD resolutions up to UXGA (1600 x 1200 @ 60 Hz). The analog interface includes a 165
MHz triple ADC with internal 3.3V reference, a Phase Locked Loop (PLL), and programmable
gain, offset, and clamp control. The user provides only 1.8V and 3.3V power supply, analog input,
and Hsync. Three-state CMOS outputs may be powered from 1.8V to 3.3V. The MST5151LA
on-chip PLL generates a pixel clock from Hsync. Pixel clock output frequencies range from
12MHz to 165 MHz. PLL clock jitter is typically less than 500 ps p-p at 165 MHz. The
MST5151LA also offers full sync processing for composite sync and Sync-on-Green (SOG)
applications.

Digital Interface

The MST5151LA contains a DVI(HDCP) 1.0 compatible receiver and supports all HDTV
formats (up to 1080p) and display resolutions up to UXGA (1600 x 1200 @ 60 Hz). The receiver
features an intra-pair skew tolerance of up to one full clock cycle. With the inclusion of HDCP,
displays may now receive encrypted video content. The MST5151LA allows for authentication of
a video receiver, decryption of encoded data at the receiver, and renew ability of that
authentication during transmission as specified by the HDCP v1.1 protocol.

Fabricated in an advanced CMOS process, the MST5151LA is provided in a space-saving
100-lead LQFP surface-mount Pb free plastic package and is specified over the 0
temperature range.

B. Video Decoder (video)

The SAA7117 is a highly integrated NTSC, PAL, and SECAM video decoder support for high
quality LCD-TV video applications, SAA7117 supports NTSC/PAL chroma and luma separation
using a 2-dimensional adaptive comb filter for reducing the cross-luma and cross-chroma artifacts.
The frame buffer is also use for 2D noise reduction circuit that resumes good visual quality when
the input signal is a noisy video source

The SAA7117 10-bits CMOS Analog-to-Digital Converters(ADC) at four-fold ”ITU656”
oversampling(54MHZ);Sixteen analog input pins.allowing fo multiple combinations of
composite.S-Video component video;Eight 3-level capable sensor pins for D-connector or SCART
AV- and RGB- switch signals(three of those can be active simultaneously),one Fast blanking
input;Level sensitive fast blanking(RGB switch control);I²C read back of digital AGC gain factor;
The component, composite, or S-Video signals are sampled at a free-run external clock frequency
(10~58.6 MHz). After the video decoder processing, the video data was sent out with a line-locked
alignment rate (24.576 MHz).

The SAA7117 comes with 160-pin QFP package.
